AMD FX...Ahead of time??

post #1 of 43

'AMD FX Bulldozer series is flop'
'Bulldozer's were hyped'
..I'm sick of such comments rattling all over the web.

Here is some interesting data from one of the reviews....
" In Intel Core i5 And Core i7: Intel’s Mainstream Magnum Opus, I brought up specific optimizations "in Windows 7 that were the product of collaboration between Intel and Microsoft—notably, core parking. Windows 7 intelligently schedules to physical cores before utilizing logical (Hyper-Threaded) cores."

In theory, AMD could benefit from the same thing. If Windows were able to utilize an FX-8150’s four modules first, and then backfill each module’s second core, it’d maximize performance with up to four threads running concurrently. This isn’t the case, though. According to Arun Kishan, software design engineer at Microsoft, each module is currently detected as two cores that are scheduled equally. So, in a dual-threaded application, you might see one active module and three idle modules—great for optimizing power, but theoretically less ideal from a performance standpoint. This also plays havoc with AMD’s claim that, when only one thread is active, it has full access to shared resources. Adding just one additional thread could tie up those shared resources, even as multiple other modules sit idle.

I think bulldozer isn't bad architecture. Its just the lack of applications that can utilize his ability. May be AMD is thinking ahead of time(Just like when first dual core was launched windows xp was lame in getting the most out of it). Yeah. AMD must have failed to beat their own phenoms but that is because in today's environment bulldozer is just ahead of time.
I know its not full proof multicore computing. The thing that each bulldozer module shares 'instruction decoder' and 'cache' is what I found a bit odd. Never the less I hope second generation of FX will surely blow away everyone's mind:thumb:

Bulldozer is a good CPU. It just wasn't a big step forward from the high end Phenom II CPUs. Just ignore the hate. It doesn't change reality. Win 8 will improve scheduling some on the FX and later AMD CPUs. Piledriver will also improve on performance. It's an evolutionary process.

It isnt a bad cpu at all, some intel kids are creating a bad name about amd fx, i had 2500k it was awesome at gaming but equally bad in VFX and 3D rendering, so i bought fx-6100, i am not finding major difference between 2500k and fx-6100 in gaming but in 3d rendering and VFX, fx-6100 is fast and cool and main thing doesnt consume much power.

This has been overly discussed.

Bulldozer was thought for an environment in which Microsoft had the CPU optimized for it, where software was compiled using the AMD optimizede flags instead of simply compiling for Intel, and above all, was thought for a kind of work we're just starting to see surface.

This architecture is well ahead of its time. Paired with an Intel market dominance and that the x86 standard is owned by Intel, you have that the processor does what it can with that it has available. And it's not much.

Well I want to go for a FX-8120 @ ASUS Crosshair V Formula. I don't know how far I can go with a V8, but I think I will just give it a try thumb.gif.

May be its over discussed. But i wasn't the part of it previously. I joined forum first time few days back. So kinda intense in sharing my thoughts w/o checking any previous discussions!tongue.gif

I know they clock like demons most run at 4.4 with little to no effort and some have reached over 5ghz with a little work. with good cooling and i dont mean ln2 I'm talking a good good w/c loop i could honestly see them hitting 6ghz with a little tlc.

If you look at Bulldozer as a foundation for later processors it is great. The architecture is well designed and has somewhere to go. However, if you look at Bulldozer as a CPU that was supposed to succeed the Phenom II it is a horrible processor. I choose to see it as a foundation for later designs. I don't believe it's ahead of it's time. I believe its a design that needs to get some bugs worked out.
