[OBR] AMD FX-8350 "retail?" performance - Page 3

post #21 of 131
And still single threaded performance is worse than Deneb...
Multi-threaded performance seems to have improved a lot over Deneb,
credit goes to BD arch I suppose.
Good effort, let's hope these are fake.

Yeah, the 3870K (Radeon 6550D) performs 30-50% better than the 3770K (Intel HD 4000) in games like Crysis and Dirt 3

the Int spec tests show BD is pretty good, the FPU single thread tests look decent to, only a handleful of synthetic benchmarks, that are heavily fpu dependant show any regressions, and those are rather trivial old benchmarks that suck becuase AMD did not optimize for old instructions.

To bad for old crappy software I geuss.

I felt the same way about a 2500k that I installed in my benching Rig today. It felt like molasses in winter even though I know it is a decent chip!

You know that single thread load gets distributed in many threads and processors rarely run on the highest turbo speed, right? There is much randomness involved when running one thread load on processors in their stock settings.

Sorry, this is a part of the official review he is working on. It is most likely correct.

If they kept the Bulldozer modules but reused and readopted the older Phenom II architecture, they'd be able to pull this off really easily I think. But it's like tinkering with a Pentium 4 instead of reworking the older, faster, CPUs from before. frown.gif

If this trend continues, AMD WILL go under and we'll be stuck with Intel... Not good. frown.gif

Right. Because you obviously know a lot more about engineering a CPU than the engineers at AMD. Because AMD absolutely wanted to put out an inferior product. Because they were too stupid to realize the design had no potential when they started work on it more than 3 years ago, and they didn't realize that at any point during those years.

Finally someone that makes sense. AMD chose to bring out BD, it is a new architecture and they just couldn't tweak it to the specs they would want it to be. No way are they now releasing a tweaked architecture that is slower. People can be Intel fanboys all they want, but claiming that means there is no reason in you at all. Piledriver will use less power, will be faster clock for clock and have a higher clock. By how much is anyones guess, but they will not bring out an inferior product, especially not now they are stopping producing the Phenom II series.

Right....
Phenom II is only better than Bulldozer in terms of decode bandwidth, maximum theoretical throughput per core, a more adequately sized L1-I and L1-D Caches, a more responsive L2 Cache, and a significantly lower penalty for branch mispredictions.
Bulldozer has better Branch Prediction, more efficient decoders, better scheduling, better memory controllers, and a bigger L2 Cache. The reason Bulldozer failed is that these improvements aren't good enough to combat the huge increase in pipeline depth and a higher latency L2 Cache in lightly threaded workloads.

That is not a matter of wanting, that is all about what CAN they do at the moment and they CANNOT develop anything better because of time, and perhaps financial and personnel resources too.
