I really hope they do well, Intel really needs tougher competition.

Intel has at best 2 generations of fabrication advantage left, before the cost to node size sky rockets so high, that everyone must co-operate.

If Ivy is 50% faster than PD in single thread, that also means an i7 will be roughly 50% faster than a 8350 even at 4 threads because it has 4 physical cores. AMD starts to catch up after 4 threads because hyperthreading is not as good as the modular PD design for heavy multi-threading.

I haven't seen what Haswell will do, but I think Steamroller will beat Ivy in multi-thread when 8 threads can be used, but it will still be behind in 5-6 threads or less.

Obviously, but remember that the IPC changes based on different programs, that's why an FX can beat an i7 at 7zip but only beat an i5 in most other scenarios where all of its cores are used, the difference also varies by core count and how many cores are used...There are times when an FX has higher IPC than an i5 but clearly more times when it has a lower IPC.

I think AMD is really focusing on development of Radeon, FirePro products to do both CPU and GPU tasks(GPGPU) . MPP is really way to the future , This slide really sums up what I'm saying:

sounds nice i have the zambezi 6100 original and serves me good but would jump on these sas soon as i can get the 6 core new chip

No, Kaveri APU based on Steamroller core was supposed to release this year, not the FX, Opteron processors.

looks like 2/3 of that transcoding statement is a fail (and only barely correct on the latter third . . .)

that may be the case, but compare the 8350's ~$180 price tag to the $320 that 3770k will cost you.
post #239 of 718
pro software is not like gaming software at all though. but if they really do adopt multicore processing in gaming to a greater degree, that data ^ will be more relevant

An 8-core Bulldozer (you don't even need Piledriver) would be faster than PS4s Jaguar, even at the same clock speed.

Better off with this than a PS4?

Mostly an apples and oranges comparison...

Yep.

A good portion of i7 920 and 930 D0s are capable of a 50%+, 24/7 stable, OC on $50 dollars of cooling.

I challenge anyone to show me a 24/7 stable 6GHz Vishera on 50 dollars of cooling.

Definitely worth pointing out.

The right tool for the right job.

For "general use" and gaming, I'd probably favor the 3570k, but for my dedicated transcode or virtualization boxes, I'd take an FX-8350 (well, if i didn't already have something faster).

A bizarre statement, since a CPU can be used to process almost anything, almost by definition.

The AMD architecture? Like there is only one?

Optimizing for Jaguar won't benefit Bulldozer/Vishera/Piledriver any more than it will help Intel's architectures. Indeed, Jaguar is architecturally as different from modern AMD desktop CPUs as from Intel CPUs, if not more so.

Even if this were not the case, optimizing for AMD wouldn't necessarily overcome the performance gap in certain tasks.

In all fairness, Cells SPEs aren't really general purpose and can't really be directly compared to symmetrical, general purpose, CPUs found in PCs.

The SPEs in the PS3s Cell BE seem to be most heavily used for graphical pre-processing to make up for the weak shader performance of the RSX.

This generally is not the case, though the FX-8350 is at least competitive in well threaded games.

Jaguar is certainly a step up, but is still most closely related to Bobcat.

the 12.09 fps of the i7 would more than certainly make up for it.

and you have to do the first pass before the second, no?

How much x264 encoding do you do?

I do a lot of it and 2nd pass is much more relevant because it takes much more time, as you can tell by looking at the fps figures in your graph (a given video almost always has the same number of frames run through the first and second passes).

The 3770k and FX-8350 are essentially tied in x264 performance.

Yes, the FX-8350 is a significantly better value for an encoding box.
