AMD, in the past, actually bundled some (not all) decent heatsinks with their higher-end CPUs. They even had heatpipes and copper contact plates and not just blocks of aluminum.

That being the case, this advancement in design is certainly a step toward progress and should serve AMD users well.

In what bizzaro alternate reality did I wake up where Don works for DAAMIT, and the stock 125w copper heat-pipe cooler (with the solid copper base) has a laser-cut LED logo and silent fan.

It's chaos -:ouch:-
Dogs and cats living together
Republicans embracing Obama
Intel guys enjoying AMD, too

It's possible. The Internet has a tingle running down its backbone. Could it be true? Only Don can tell . . . .

AMD for Life! Intel for the Wife!
(Thunderman Lives!)

Congrats, Don, and great start. To Polaris and beyond!

It looks like the cooler from their older socket 939 opteron CPUs

The Latch. We can only dream that Don will lead the charge for AM4 compatibility.

Those old Opty coolers are the best. The copper slab for the base was 3/16ths-inch thick.

 


The power consumption of small LEDs is minuscule. The shroud is just a fan shroud; it's not for the whole cooler (almost all fans have one) not a whole shroud. You'd know that if you read the article or even looked at the pictures. The cooler is fairly quiet (much more so than its predecessor and Intel's stock coolers) and should have decent performance for a cheap cooler, maybe a bit below a Cooler Master Hyper 212.

If it isn't going to be bundled in with lower tier CPU/APU's then I'm already with a sad smiley :( Hoping AMD change their mind...

...why would they bundle it with lowest-end stuff? The low end parts don't need it, and anyone that wants/needs upgraded cooling knows where to get it. This is a nice upgrade for the higher-watt parts and should be more than sufficient for anyone that isn't overclocking.

Don, Great you're there now.
Yes, AMD needs more marketing and out-of-the-box thinking!
And Marketing marketing marketing!
I've been working with AMD stuff since I was a kid, and only between 1980's till 1990's that people in our country (Philippines) knows AMD.
Nowadays, if you talk computer, people only knew 'Intel' but not AMD. Computer jocks and the like knew Radeon, but not AMD..
SO we also need marketing down here..

Still, it is cool... but OEMs are going to have their own coolers, and most of their customer base will replace it with an aftermarket cooler... wouldn't it make more sense to just have the simple quiet redesigned cooler built as cheap as possible, and then have a few larger fancy aftermarket options (with higher markup) to let the AMD enthusiasts (of which there are many) help support the company with a few extra purchases.
Actually, it's this line of thinking that has given you this skewed viewpoint in the first place! The old coolers were crap (noise-wise), thus everyone felt compelled to replace them with aftermarket coolers. However, with a quiet stock cooler, your AMD vs alternative Intel build comparison will look $30 cheaper toward AMD now since you won't need to factor in an aftermarket cooler for any non-OC build (which is WAY more builds than the enthusiast OC rigs).

41 upvotes...LOL. I love AMD, but 42 people seem to be missing the point (including yourself).

You're idea of "IN THE GAME"=
Losing 7B over the last ~15yrs, and I can't even remember the last PROFITABLE FY. Over that time amount of shares have nearly doubled (diluted that is, as they kept devaluing them to get more credit, like the fed keeps printing money we don't have).
NV now has over 81% of discrete (gaining yearly from 63% a few years back).
Intel owns the whole show now on cpu, basically same for apu/server.
AMD margins in toilet (while NV/Intel hitting highs Q after Q, with both having profitable year after year).
Had to sell fabs, land, lease land etc. Only things left is IP really, and that won't be worth much soon if the next gpu/cpu are not a huge hit. At current burn rate, they might make it 2yrs before selling out, or bankruptcy or going further into debt. But that latter deal is difficult considering their now "junk bond" credit rating so to speak.

They are no longer a LEADER in anything, which is precisely why they have ZERO pricing power and margins so low. This isn't AMD employees fault, it is a MANAGEMENT problem. If ZEN is smaller than Intels FULL CPU/IGP die size, they will lose yet again. They needed to take all of Intel's gpu side and pour it into CPU. That would have made for a WINNER, but I fear they went with about Intel's cpu size and will just end up priced to death until Intel can either blow them away again, or maybe just drop higher clocked models to edge out AMD (if even that is needed). They are not going to run away with the gpu race, but they have the first chance since 2000-2003 to run away with cpu since Intel dedicates 1/2 the silicon (more in upcoming chips) of their die to GPU now. They would be left with the same choice as AMD has been recently (going 8 cores, usually not utilized, and running hot/high watts), until they could properly design a HUGE quad again. AMD might have 3yrs to rule and PRICE higher than Intel and possibly get out of debt during that time. From all the data/leaks I've seen though, I fear AMD just tried to match Intel's CPU side (die size I mean) instead of going HUGE to dominate.

If they didn't go at least 1.5x Intel's cpu side, management should all be fired. This is their last chance to produce a winner in a time where Intel has been concentrating totally on ARM for years. Intel isn't prepared to see a quad die the size of their entire cpu/gpu. Even 1/2 of the gpu side would be ok and probably win most stuff, but Intel would simply sell 8c models for the same price until they get something real out the door. But if they went really close to full Intel die size, even the slapping of 2 Intel quads together wouldn't win much (see how well AMD's 8 cores do now vs. Intel quad, due to so little software REALLY using 8 cores efficiently), so AMD would have a few years for Intel to fix things giving a few years of great profits. Before when AMD had a winner they had no ability to really product more than 20% of the market. This time would be COMPLETELY different as they could fab at TSMC/GF and possibly samsung (as they share everything with GF and it wouldn't take too long to tool up at samsung if desired). AMD could really make a HUGE dent in Intel profits, market share, and R&D over a 3yr period or so (maybe longer, as Intel would need a radically different design to catch a really high IPC quad that big). Even going to 10nm would not help Intel win, it would merely lessen the blow due to smaller silicon than 14nm and edge them closer in perf.

DX12 was being worked on about the same time as Mantle (with NV BTW) and NV was chosen to run and XBOX1 game (forza, made for AMD on consoles) to DEMO DX12. DX12 is not based on Mantle (For that matter even Vulkan is FAR different, which isn't to say bits weren't reused, just the whole product is very different).
http://www.pcper.com/reviews/General-Tech/GDC-15-What-Vulkan-glNext-SPIR-V-and-OpenCL-21
Note the main selling point of Mantle was that it was HLSL.
"Khronos is doing something else entirely." IE Shader compilation is completely removed from the driver etc..etc.

Not trying to be anti-AMD here, just laying out facts you seem to be completely ignoring. Financial reports don't lie. Market shares don't lie etc. You can say it's amazing they're still here (testament to great engineers in the face of moronic management decisions), but not that they are IN THE GAME so to speak. They are losing their butts in everything cpu, gpu, drivers, gsync (while expensive) better than freesync, mantle killed (well duh, poor guy can't start his own API with 20% share to push it), pushing console mistake (far too low of margins. should have passed like NV), 3rd party for Geforce Experience competitor (again not as good), etc. Money spent on consoles totally stalled R&D on PURE CPU/GPU which is why they lost the cpu race and lost all that share of gpu to NV while drivers suffered too. This is exactly what Jen said as the reason why they passed. It would take too much away from R&D on core products. Fools took that as "butt hurt NV over losing consoles". No, VERY SMART management realized bean-counters were right, margins were not worth stopping R&D in CORE products and support for those core products.

I really hope AMD capitalizes on the first time in a decade they could produce an actual winner (have 2x the size of Intel's cpu core to work with on same process essentially) and easily capable of producing massive amounts of chips between multiple fabs unlike any other time in their lifespan. I'm astounded AMD pushed the PURE CPU for moving up GPU. Their GPU will be running against a highly competent NV chip, while their CPU (IF HUGE) could have wasted Intel in perf for at least a few years. If they cpu is HUGE, they can still win for a while, but it should have came BEFORE gpu, as NV/AMD are both working from the same place and neither has a way to dominate everything like you could with a 2x cpu die size that takes YEARS to design (4-5 usually, like russian roulette, only you don't find out your dead for 5yrs). Intel can maybe speed that kind of thing up to 3-3.5 but not more than that no matter how much money they throw down. Intel's only option for years would be to plop two down (running hotter, more watts until gpus stripped), or shrink to more mhz with 1 or 2 quads sans gpus. Neither way works to win, just lessen the pain. You can't really price to death a king in perf either. Intel can't afford to do much of that for 3yrs while trying to keep samsung, TSMC, GF and all of ARM off their backs. AMD could price a huge die at or ABOVE Intel current pricing at all levels. Intel shareholders would not stay in the stock if they saw cpu margins tank (along with profits) to price AMD to death. A loss in billions of Market value gives Intel far less competitive room to move against all others mentioned. They would likely have to keep pricing pretty high in the hopes most wouldn't go for AMD massively at higher prices. It would be interesting times for Intel for sure no matter how you slice that...LOL. APU's have no shot either, as they are priced to death by ARM coming up, Intel moving down. The HUGE cpu is the only thing that can make AMD real profits for a few years straight.

Again, I really hope I'm wrong about what MANAGEMENT chose to do with cpu die size (already wrong pushing it out for pulling in gpu). The Zen CPU needs to be 1.5-2x Intel's cpu side or they blew it. I'll buy AMD for a WINNER even at $100 over Intel, but I won't buy AMD for a tie or anything close with no sign of another product that will make serious cash to keep them afloat for years to come. I feel sorry of AMD employees who keep having to follow incompetent leaders who sabotage their ability to produce winning products. I hope management went for the CLEAR WIN (and pricing power for years), not merely matching Intel cpu die for silicon savings which amount to nothing in a tie and instantly bring price pressure to stop AMD from gaining share or making profit. Being competitive isn't enough, they have to have a WINNER this time (see being semi-competitive for the last decade, it got them NOTHING but loss after loss yearly). Dirk Meyer was right when he said AMD needs a KING first before trying other crap (consoles, etc), as he left the company in ~2011. I hope they stripped the GPU side to make a KING cpu, rather than some silicon savings for a tie or worse. Stripping gpu and making cpu marginally bigger probably just gets close to Intel, but that won't give a billion in profits for the year (can't save that much from smaller silicon as Intel moves to 10 and prices down again) for years like a HUGE die that actually WINS would. A silicon savings (on such small share anyway) would only raise margins a few points and only until Intel hit 10nm shortly after, but a winner could raise them 25 pts and produce huge profits for ages.

I hope people get the point. I hate management at AMD, not AMD workers or the company. I'd really like to buy their stock again one day too! But not until I see a ZEN die size that amazes me. You're not IN THE GAME if you're losing money, market share, buildings, R&D dropping for 3yrs etc etc, while the exact opposite is happening for NV/Intel.

don, congrats on making the amd stock HSF seem relevant again. oh, on your new job too. :)

btw, niels... "greener pastures"..? surely you jest... :pt1cable:

now where's angelini gone....

Hah, I have to cop to it: The "greener pastures" was my edit. A little tongue in cheek. :) We're happy for Don, but we also miss him!

Angelini is still very much a part of TH. Just a different role.
 


I agree with you about AMD's management, but what are they going to do with all of those transistors? Brute forcing the CPUs with more X more Y more Z has huge diminishing returns, especially with most consumer workloads that aren't very parallel. That's why AMD and Intel don't do that. More transistors need to do proportionally more work and they just don't. You can throw more resources per core, but if the workload can't be forced into being parallel enough to use them, then those resources aren't helping. You can throw more transistors to things like the branch predictor and such to try to improve utilization, but the increased complexity tends to increase power consumption more than performance nowadays when those components are already limited more by the code fed to them than by them having hardware deficiencies.

Larger dies have other consequences regardless of that. Increasing the distance that a signal may need to travel can greatly increase the power it takes to send that signal and the amount of time it takes for the signal to get from point A to point B. You might increase the size of the die by 50% and at best increase performance by say 20%. The increase in power consumption would vary widely depending on many factors regarding what was changed and what the changes were. However, we know for a fact that costs of manufacturing and binning would go up by more than 50%.

You start off at 50% more expensive because you need 50% more die space per CPU. Binning would increase the costs past 50% because you'd get far more faulty dies since the chance of an error scales exponentially with linear increases in die area. How many people are going to buy a CPU that costs say 75% more for a 20% gain in performance? That isn't going to sell well, except for people who's income is dependent on the computer's CPU performance and the initial cost of the hardware is largely irrelevant. Most related applications for such work are either parallel or you can run multiple single/lightly threaded instances simultaneously, so a higher core count that would run much more efficiently is almost always more attractive, so we're back to the CPU not selling well.

Basically, increasing die size by 50% for the same core count would not help AMD "get back in the game". They need to make things work efficiently like Intel did with Sandy and then work from there. Increasing die area for the cores so much is counter-productive if the performance improvements are by far less than directly related, especially when costs increase by even more and power consumption is most likely going up too, dragging efficiency below what AMD currently has.

Improving efficiency may demand a somewhat larger percentage of die area for the CPU cores, but 50% more than Intel? That's not feasible.
 
Hey, Blaze?
GloFo transistor density at 28nm SHP is damn near the rough equivalent of Intel transistor density at 14nm with Broadwell. Intel has decided that Skylake information relating to die size and transistor counts "are no longer relevant to the end-user experience" and are not likely to be released. Fancy that.

I do not disagree that Intel may harvest more dies per wafer, but without knowing specific yields it's almost a specious argument. 28nm SHP is a mature process with presumably higher yields than a newer 14nm process, even if they are Chipzilla.

It's not as black and white as you make it out to be. There is a lot of gray in there.

Regardless of how it compares to Intel, a better stock cooler is worth it. Even if you buy an aftermarket cooler (like I did), you still need the stock cooler as a backup, should the aftermarket cooler die (which mine did). Long story short, a better stock cooler=backup cooler that can still cool the processor in extreme conditions. I wish I could trade my stock cooler for the one in this article (EXACT same processor as shown in article).
 


I didn't go into the misleading transistor densities between the "current" process nodes on purpose :) It wasn't necessary for what somebodyspecial and I said, which was mostly about transistors per square mm and how many square mm there are per die rather than a specific process node. I avoided discussing the diminishing gains from die shrinks because of the gray area you're bringing up; that's why I first compared Vishera to Sandy instead of to Skylake and the others.

Though to be fair, the process node measurement in nm is distance between transistors, not the size of the transistors, so it is certainly not the only factor in transistor density as measured in transistors per square mm. As the process node gets smaller, though the transistors usually can be made smaller too, they are not necessarily smaller in a direct relationship to the decrease in distance between them. This means that the transistors can take up a larger area relative to the space between transistors as compared to a "larger" process node. How much this comes into effect is anyone's guess thanks to Intel's zipped mouth on the subject.
 
AMD is not going to drop off the face of the planet. Even if Zen isn't a success and AMD files bankruptcy, they will continue to operate. They will flush some of their debt and reorganize what they can't flush. Their stock will take a hit, but they won't be going anywhere.

Intel has a vested interest in keeping AMD afloat, but not too big (this is part of the reason we've never seen a multiplier-unlocked I3). They are the only company with an x86 license. If AMD disappeared, Intel would have to find another company capable of producing x86 chips and get them a license quickly to avoid antitrust issues. The non-transferable license keeps AMD from getting too big; forcing AMD to develop on the resources it has rather than find a buyer with Intel-level cash to spare.

Nvidia is in a somewhat similar situation, though they can be less obvious about it since AMD's cards have more market share than their CPU's.

AMD will still be around even if Zen isn't huge. The sky isn't falling.
 
Off topic: AMD was a part of the DX12 consortium from the start and was intimately familiar with the API details and requirements. According to Ritchie Corpus, AMD's director of software alliances, AMD shared it's work on mantle with Microsoft from day one. This may be a large part of the reason porting from Mantle to DX12 is a breeze.

I love AMD. That being said..... You guys need to get back into the game and give Intel some real competition.
Is it that Intel has more money to throw at projects? I really like your Wraith Cooler. Go Get em! Make us proud!

Hallelujah ! Well it's about time!. As a system builder this is great news having had to use aftermarket coolers for standard FX processors for some time now. The reference coolers don't cut it at all in the Australian heat , let alone for overclocking..

Given the climate shift this last decade. It shouldn't be as hot in Australia. The shroud itself could offer additional cooling properties. It increases pressure in the fins and allows air to flow past the bottom of the fins. Would require comparison testing.
