[citation][nom]ronch79[/nom]AMD doesn't seem to be able to get past 4.2GHz even with the PileDriver cores. That's a pity especially since they originally intended the FX lineup to run at high clocks. Also, I don't understand how it's a 'plus' if the new FX chips support all those fancy AMD stuff such as Perfect Picture HD and AMD Steady Video 2.0. I mean, does this mean I have to get an FX to get those features? Does it work with either an AMD or Nvidia graphics card as long as I have an FX? So if I get an Intel CPU, I won't be able to get those? Isn't that artificially limiting the capabilities of the system so you get an AMD CPU and GPU? Aren't those nifty features a function of the GPU and not of the CPU?[/citation]

If you get an Intel CPU and a Nvidia graphics card, then AMD's feature isn't limiting anything for Intel and Nvidia. If you get the AMD CPU and graphics, then you get the feature, assuming that it's anything more than a marketing ploy. It isn't like Intel doesn't have competing features anyway.
 
Blaze, palladin, you seem to know about this.
Is there any software way to optimize thread scheduling in Win7?
I ask this because not many gamers will go into Win8, which has these improvements. Most of us, for gaming, will remain in 7.

I already use Linux for some engineering tasks and its just amazing to see how my FX runs. But the thing is that most of the software developers, and Windows itself, dont take AMD into account when programming.

Besides, you guys should write a post on the forums, a HOW TO make the tweaks you speak about. I am familiar with my BIOS, but I cant really understand how to make that change. Probably many other FX owners dont know either.
 


Well 4gz is a lot for a default clock, isn't the 3770k clocked as far as 3.5gz? Obviously they aimed for a nice 4/4.2 with turbo which is a very nice improvement from BD, not to mention everyone knows any processor's speed is judged not only by benchmarks but by it's OC capabilities. BD proved to be a very nice OC processor (5ghz on air with 8 cores enabled is a lot) and PD is going to be even better, I think 5.5 on air and maybe 6 on liquid.
 


Depending on what Tom's review is I will most likely get the FX8-350. I'll wait though and see what their numbers on single and multi-threaded performance return.

Using PSCheck I should be able to get single / dual core speeds to ~5.5 while underclocking the others. Golden chips might go even higher though you start smacking into a heat ceiling pretty quickly.
 
[citation][nom]madjimms[/nom]65-95W, NO HIGHER![/citation]

LGA 1366 and LGA 2011. They don't need to have low TDPs. There will be lower TDP models (at least down to 95w) and if you want lower, then you can simply undervolt/clock one yourself. It wouldn't be any cheaper to buy one that way by default.
 
[citation][nom]rohitbaran[/nom]Go AMD, give Intel some competition. It is really bad that even the highest end AMD processor right now gets beaten by the SB i5s in mainstream applications (correct me if I am wrong).[/citation]

I recommend reading some of the other comments of this article, specifically some of my first ones.
 
Pretty Sure the E2-1800 is already out.
On the new Vishera Cores, 4 GHz stock seems pretty great but you have to wonder. The Phenom II originally had a high clock, but could not overclock that well because they were already around their limits stock. This just might be something similar.
Also the main problem with the cores is not with performance. They have a pretty high theroretical perfomance with a larger die then Intels chips. The problem is with software support. The OS and other software sending stuff to the processor has no idea what it is doing so they end up not making use of the architecture. For instance Guild Wars 2 making use of only 1 Bulldozer core.
If they work with Microsoft and some game engines, they can vastly improve performance on these chips.
 
[citation][nom]ojas[/nom]Well, i won't claim to know the "truth" about bulldozer's performance, since i don't own one.However, i'd like to say this: At least compare stuff at the same clock rate. If you want to compare a bulldozer cpu to a previous generation AMD cpu, at least use the same clock rate and core/module count. Don't say stuff like "OMG bulldozer at 4GHz beats a Phenom II at 3.5 GHz!!!!"..[/citation]Why? Why insist on crippling the part that has a higher stock clock speed? Compare stock to stock, of course. But comparing two CPUs on IPC alone doesn't tell you the final performance of each model. If a 125 watt AMD part beats a 125 watt AMD part, both at stock speeds, don't worry about the frequency so much. Frankly, even BD overclocks/tweaks better than Phenom II, and I don't consider BD to be a very good chip.

Thankfully these Piledriver based chips should boost stock clocks AND IPC at the same time. If they also stay reasonably priced and overclock as well as BD, we might be in business.

Most of us, for gaming, will remain in 7.[/citation]Speak for yourself. Win8 is chock full of performance improvements, and the upgrades are discounted initially. I don't mind Metro since I love the keyboard shortcuts and search anyway. As long as it runs Steam and all the games that 7 does (it does) then I'm good.
 


Actually, I think that Piledriver will have no trouble at all hitting far higher frequencies than Bulldozer did. A lot of the improvements were in power consumption and from looking at some of them, they seemed to have been designed specifically to not limit clock frequency. I have no doubt that Piledriver will reach for 6GHz on air cooling just as Bulldozer reaches for 5GHz.
 


You forget that Microsoft flatout sucks at programming. Ask anyone who worked for Microsoft in programming department, they will tell you a lot of nightmares about all the hack jobs they employ, and hack jobs to cover over hack jobs. No, you are better off installing Ubuntu, games need to go to Linux, along with Steam which is going to Linux.
 
Are you kidding? My FX-8150 CRUSHES any and all intel equivalent when I compare then on Linux. Now since I run everything on Debian Linux (including Windows via VIRT) it still CRUSHES the charts compared to Intel. You don't have to like it, but it's true. The problem is MS can't write stable, multi-threaded kernels. Linux / Debian already do. Up to 256 cores and near perfect memory management. I run 8 Virtual Servers from the FX-8150 and the kernel never has a swap file...EVER and I only have 8gb ram total.
 
[citation][nom]nebun[/nom]isn't 2012 almost over?[/citation]
if by 'almost over' you mean we still have 33% of it left, then yes. Thats 4 months bro, get a clue.
 
[citation][nom]fuzznarf[/nom]if by 'almost over' you mean we still have 33% of it left, then yes. Thats 4 months bro, get a clue.[/citation]

Isn't it closer to three months considering that today is the 29th? I'd say that it's more like 25% of the year to go and that is 33% more time than has already gone this year, not 33% of the entire year.

September, October, November, December still remain in the year.. we are IN AUGUST. that leaves 4 full months... wow... seriously.

thats 4 months.

let me do the math for you
there are 12 months in a year.
there are 4 of them remaining.
that gives us an equation of 4/12
which is also equal 1/3 when reduced
thats 1/3 (pronounced 'one third') of the year left.
'one third' is 33% (pronounced 'thirty three percent')
4/12 == 1/3 == .3333 == 33%
so yes, we have 33% of the year left... i dont know what kind of math you are doing that tells you 4 out of 12 is 25%?

Blaz, sometimes I think you just want to argue.

Sorry my clock screwed up and I made a mistake. That was no reason to jump the gun like that.

I know dude. I was just being jerky for the fun of it. I've been known to think sideways from time to time also.

they better hurry up...AMD has been know to delay most of their product launch....get the point?
 
[citation][nom]blazorthon[/nom]Can you give more information before declaring that? Are you running any other programs while you're gaming, what background programs do you have running, what OS are you using, and can you give us screen shots of CPU usage before, during, and after gaming (maybe on another monitor, IDK) of the core utilization of all cores in your CPU? Did you take into account that with that much of an underclock, even many background things such as Windows itself, AV and related programs, and much more can have a significant impact on CPU utilization? What maps are you playing and how many players are on them?Also, 90% is not maxing out. Assuming that you're playing multi-player, that's up to six cores that the game alone can eat up. Windows and such need to run on something, so they probably take most of one core and some of another (or split evenly between them, w/e). Point is that just because your utilization is that high, that doesn't necessarily mean that BF3 is maxing out all of your cores. I know for a fact that it only has up to six threads (two for the game engine and four to handle the other things such as players).You colud test this by overclocking rather than underclocking to minimize the impact of background tasks and after that, you can also temporarily disable one module to get three dual-core modules and compare gaming performance. Considering that I already know that the FX-8150 can't even beat the FX-4170 at stock in most games and Tom's has proven that much, I'm quite sure of what I'm saying. Also, considering that the FX-8150 has almost as much performance when all eight cores are stressed as an i7 does with all four cores and virtual threads stressed, you'd be beating the i5s with that CPU (even at similar CPU frequencies) and I find it unlikely that you're beating the i5s in the full core configuration of an FX CPU in any game. It would need to use eight threads effectively to do that.[/citation]

Many games released today already use multiple threads effectively. Battlefield 3 is already proven to use this many threads for the rendering process. In similar respects, Shogun 2 Total War also will utilize all available cores. I find that even clocked at 4Ghz with my FX-8120 it still uses over half the cores. There are no 'background processes'. Modern PC games are purely coded with multicore in mind. They may not be perfectly multithreaded with an even balance, but they aren't single threaded either.
 
Anyone who serious thinks Microsoft is good at programming has never seen the C# garbage they invented. I have never seen such an awful, unhelpful programming language in my life. Microsoft will personally employ around 3-7 programming languages to do a single task, there is absolutely no consistency with the programming, it is a hack job at best. Many of them outright despise C++, calling it garbage, which is absolute nonsense.
