I guess we will have to wait and see. Producing the chip and how well it works are vastly different. I know Intel was talking about lower nodes having issues such as the CPUs wearing out and the possibility of a CPU having backup cores.

Guess we will see how that happens to play out.
 


Basically taking more enterprise grade compute solutions into the consumer space. IBM has what they call hot swap cores. Available cores that can be switched on when needed to replace a core that has been generating too many errors. Once the systems are installed they don't really want to rely on physical maintenance to keep the performance up on a monthly basis.

 
Just to keep things in perspective first if Microsoft bought amd they couldn't produce x86 parts anymore second zen isn't completely new Jim Keller said he took the best parts of several designs. Last bulldozers benchmarks became more reliable the last 3 months before the release with 3-6 months before it motherboard companies thought something was up due to low performance and a low clock speed.

 


Zen is AMD's child. Zen will have the same basic elements than any other high-performance server-like core from Intel, IBM, Broadcomm... Zen core will be a superscalar, OOOE, SMT,... because that is the optimal point in the design space of server-like cores.

The cache subsystem is entirely new. AMD has been filling cache patents since Keller return. If patents filled are representative (not all patented work finally goes into commercial designs), Zen will have a stacked cache susbsystem. This is a cache structured to favor certain prefetching techniques that exploit temporal locality of data. Prefetching techniques are used to increase IPC and, thus, performance.

The reason for cancellation of several project, the delay of K12, the rebrands of 300-series,... is because AMD is concentrating all the efforts and money on Zen design.
 


Omg i hope Zen will be good, or at least good enough... i may even give AMD a chance and wait till they release Zen, if it´s good i may even build my next Desktop with it, if not ill just go with Skylake as planned, i got a ton of cash been saving for like 2 years and it´s itching for Skylake, but if AMD is ramping up on Zen it may actually be good.
 


Not really because someone will buy out AMD and then Intel will be forced to allow the transfer of the x86 license to keep the markets competitive.
 


In theory.... although I personally wouldn't count AMD out just yet. They are putting everything they got into Zen and we know they can produce some superb kit (as they have done many times in the past). Everything appears to be lining up for them as well- they will for example be on an equal process footing with Intel for the first time in ages.
 


Not quite equal. Cannonlake, the 10nm shrink of Skylake, is set to be out in 2016, same year as Zen. The delay for Broadwell didn't stop the other parts from continuing.
 


Given that there is no silicon out yet for any of those I don't really see how it proves anything beyond the level of confidence said HPC companies have in performance predictions. AMD have ground to make up on that score after the dozer' cores failed to meet targets.

Edit: Also I really don't understand why you make such an effort to comment here if your so *sure* AMD can't produce anything worthwhile any more. I like participating in this thread as I'm interested in the tech (all tech, advances by Intel and nVidia are also good), and I personally still think there are some nice things to come from AMD in the future. Perhaps I'm wrong, but please can we try and avoid getting into an argument to prove how hopeless everything is all the time? I'd understand if I was making statements like 'AMD will dominate Intel' but lets be honest, most people here are fairly well clued up and no one is saying this.

All we're saying is we think AMD can release another decent processor (and decent isn't the same thing as saying 'Better than Intel'). If that happens then hopefully there will be a worthwhile argument for purchasing AMD cpu's again, as currently I can't really advise people to go that way given the advantages a similarly prices Intel rig provides. At least where the graphics cards are concerned we have real choice up and down the product stack. As for what happens with the next gen, that's quite a ways off and we have no real details of either architecture so lets discuss that when there is actually something to discus.
 


1. 386 and 386 were just clones of Intels designs and while AMD was putting them out, Intel was on the next step. For example, while AMD was releasing their first 486 in 1993 Intel was releasing the first Pentium.

2. If K8 and Conroe have taught us anything it is that clock speed is irrelevant if the IPC is low.

3. Athlon XPs were ok against first gen P4s yes but after that they were a PITA to use. Your board might have booted with it but it might not have supported the proper clock speed. Had plenty of people have that issue where they bought a Athlon XP 2600+ and it would only urn at best as an 1800+.

4. Athlon 64 ws not the first 64bit chip. There were plenty before it including Itanium, which was started in development in the mid 90s.

5. And Intel proved that a MCM design can beat a monolithic design. Core 2 Quad was superior to Phenom and was still competitive, first gen, to Phenom II. Second gen Core 2 Quad beat Phenom easily. And tell me how Nehalem could have copied Phenom when its development was started many years before even the K10 uArch was announced:

http://www.geek.com/chips/pentium-8-codenamed-nehalem-under-way-at-intel-550648/

2002 was the first sighting of it.

And AMD was not the first with L3. The Pentium 4 EE had a L3 cache. L3 was just pointless until more recently.
 


There is information and correct information. I never said AMD was bad nor that they were not good value for the money. Just certain things, such as Nehalem copying K10 (Phenom) when it was in development longer.

Zen itself wont be modular. It was a bad design choice and AMD knows it. It will be a standard CPU just like an i7 with SMT which is the smarter choice to get a boost in performance for little to no real estate or increase in power consumption.

The current hope is that Zen will be competitive. I wish they were as Intel is at a stand still when they probably could have done much more. But the numbers we have been hearing are not something that is showing a CPU that will blow our socks off.

We could be wrong but we wont know until we get closer to launch.

AMD has offered value for the money because that was the only way they could sell their chips. When K8 came out and Intel flubbed with Netburst they gained a massive upper hand, although with a few issues such as the ability to meet demand and supply shortages. And when that happened they priced accordingly as they could demand a higher price. They were equal to or higher than what Intel had.

Back when Core 2 Quad came out you could get a quad core AMD setup. It was the Quadfather or Quad FX, two names it was known by. But the performance was not there, the power use was insane and it was $1400 dollars for two CPUs alone that couldn't even beat, at 3GHz, the 2.4GHz Core 2 Quad Q6600. Of course after that pricing went back to the way it was but AMD has shown a few more examples of them pricing where they think it could be. The FX 8150 came out at the same price as a 2600K and the FX 9590, well that was just insanely over priced much like most "extreme" CPUs.

AMD is a company and their survival comes first.
 


Zen will appear in an enthusiast line of CPU (no integrated graphics). Those will not be cheap. Mainstream users will be directed towards the Excavator-based APUs.
 


Oh I agree, if Zen is a monster CPU, it will come with a commensurate price tag that's for sure 😛

With respect to Phenom vs i7, I think if anything the first gen i7 rather validates AMD's design decision with Phenom. Out of interest I remember when Phenom I came out there were some interesting deep dives onto the multi core performance and they did identify that Core 2 Quad had an issue when using all 4 cores on a single application.

At the time there was so little software that used even 2 threads, the main advantage of quad core was running multiple discreet processes in parallel (which was fine on C2Q), however I think these days the bottleneck would be more apparent. As for Phenom II, from what I remember the 'battle' between C2Q and Phenom II was never all that black and white, as AMD were able to offer very high clock speeds on Phenom II and it was always a good performer in games. Even after Nahlem, Phenom II X6 was a great CPU, I actually still run an X6 at work for cpu bound rendering duties (at the time it was unbeatable value for that, obviously there are far faster processors available now although it's fast enough for the light duties I use it for).
 


Can you please post the source?

I have no information regarding anything beyond something similar to the FX branding on that line of CPUs. Which does not command a premium price.
 


It is pretty simple. Potential customers did launch open calls for proposals. Companies submitted proposals. Customers reviewed proposals and selected winners. Multimillionary contracts were signed and some systems are already being build. Systems will be operative by 2018 or so.

All customers selected future hardware from IBM, Nvidia, Intel, Cavium... IBM will provide future Power 9 CPU. Nvidia will provide future Pascal-based GPGPUs, Intel will provide future Knight Hill Xeon, which will arrive on 2017...

No known customer will use Zen, K12 or GCN2. Do you recall that recent leak about a future HPC APU of 250W that used 16 Zen cores? That HPC APU appears in the official AMD roadmaps for 2017. No known system will use it. This is similar to the overhyped Berlin APU. I am still waiting to find a server/HPC system using it. The Berlin APU apparently only can be found on paper.

The explanation for the lack of any design win with future AMD hardware is that future AMD hardware is not competitive even in the market for which it was designed. Recall Zen main market is not PCs but servers/HPC.

This fiasco is something was expected from an understanding of basic tech and economy. Some time ago I posted in the old thread a graph showing the decline on R&D and I said this was going to hurt future products: Carrizo, Fury, 300-series, projects cancellation (Skybridge, Mantle), K12 delay,... are just confirming.

As news reported about one month ago, AMD is preparing itself for a split, and I continue to maintain that AMD will likely abandon the PC market. Numbers I have suggests just that (next AMD report will show loses on all the PC markets: CPU, APU, GPU,...). There is no objective reason to believe that AMD will do a comeback to PCs and mentioning Am386 or K5 chips is going to mislead readers not familiar with history or details.
 


I thought that the Bulldozer design was based on a design that Intel had acquired when they bought DECAlpha. It was one of the two SMT methods they developed and Intel allowed AMD rights to some of the designs from Alpha (including the IMC for K8 and the module design for BD) as Intel didn't feel those designs were necessary yet (IMC) or efficient (module).
 


I still think it is possible for Zen to win some more designs possibly. But GCN 2 over KNH? Not for the uses those companies want. While Larrabee might have failed to ever become a desktop GPU it turned into a killer HPC card and has been doing very well. It is solely designed for that market while GCN is designed for multiple, gaming/design/HPC, which gives it a distinct disadvantage in the HPC market.
 


This is a major point here...

The comparison is for HPC designs...and POWER9, KNH and VOLTA are all going to be aimed squarely at HPC performance. They are going to do nothing in consumer HEDT, and while POWER9 will make a huge splash in commercial servers, etc. too...I doubt the other stuff has near the impact of POWER9 because of the established clientele IBM has in server market shares. NVidia's Volta will have zero impact on anything AMD does, outside of HPC designs, and KNH will likely make a small splash in the x86 server market as a co-processor...but it will be a very small %, of an already small %, of the world's server markets (x86 server is relatively small comparatively).
 


The biggest benefit of KNH to Intel is how it can translate eventually to their CPU designs. That is about it but it is a HPC part.

Zen needs to focus more on the server market, much like AMD used to do with their designs where they focused on server then trickled down to consumer. They used to have a pretty good chunk of the server market and because it costs the same to produce a CPU of the same specs for server and consumer yet server can demand a much higher price making the margins much better.

That is where AMD made most of their money during the K8 days, which is another reason why the consumer OEMs not selling them didn't matter as their margins there were very small in comparison. I mean do you want to sell a CPU at $500 or $3000?

That is where Intel focuses. Most of the new technology we are getting is really with servers in mind. A high bandwidth interconnect (DMI/QPI), fast lanes for add in cards (PCIe), M.2/SATAe. ALl designed to remove bottlenecks in servers then trickled down to consumers.

If AMD focuses Zen on that, to take back some market share in the server world, then they will profit way more than trying to focus on the consumer market, especially considering how it has slowed down due to tablets and hybrid laptops (Surface, Asus Transformer etc).
 


Well said, also I'll add I'm betting Zen will be focused quite a bit on power efficiency- as that will tie in well with their semi custom designs. I could see a new console coming out with GCN2 and Zen as it's basis. They have got a new as yet undisclosed semi custom win which is rumoured to be related to Nintendo. I guess we'll find out sooner or later.

Getting wins in the HPC market is certainly a nice 'feather in the cap' as they say, although in reality whilst 1 or 2 big wins are big individual orders, it's unlikely to count for much overall.
 


Exactly, they need to pickup shares in server space, and none of those design wins referenced are really going to impact anything beyond HPC except POWER9, even then...POWER9 and x86 are not going to have much overlap in terms of market segments.
 
^Yea Fury X is a bit high in price for what it is but it is selling I guess, if you consider a "out of stock" selling as I have yet to see it in stock at Newegg. Hell Fury is out of stock. That or production is just low.

And I can attest to nVidia being the work station GPU of choice. Every workstation I have built for customers or we have bought for our employees has has nVidia in them. CUDA just has a good grip on the market.
