Whauuuu First performance slide!



Testing in:
- PC MArk Vantage - TV and movies
- Cinebench R11.5

Render performance is more than awesome!!!i7 980x will be here beating!

Listing the source would be appropriate.
Good looking numbers if true.
Also, the image does not work.

[ReKcOlNu]

What speed was the CPU?

Just found this...

[FlanK3r]

CPU speed is not important, if it at stock clocks...

[ReKcOlNu]

So its probably the fastest chip they'll be releasing at launch then.

Would of really gotten excited if someone was to say,.. its only the 3GHz $199 mid-range part, the 3.8GHz $299 black edition is another 30+% faster!

[Manicdan]

where did you find the numbers? i already saw the slide but dont know where the source is for actual numbers

[Slappa]

If these are true it still does not indicate single threaded performance.

Most of these apps are multi-threaded and with BD's new design it seems that we already knew that the multithreading would be greatly improved.

If we see Pi runs that match nehalem or DB then we know there was a strong FPU/Single thread increase

[muziqaz]

Pi? Seriously?
you want to run single threaded x87 app on next gen x64 modular CPU to see it's performance?

Surprisingly yes.

Not to measure performance as a whole...but to see single threaded performance. If that has improved, then the architecture compare to K10.5 has been dramatically improved, and may actually catch up/beat intel.

Multithreaded performance is not everything, as some APPs are still coded for single threads.

If the single threaded and multithreaded performance are good then we can see a nice all around chip.

[Manicdan]

with turbo2.0 it will be really tough to say what performance will be since clock rates will be higher, and there is currently no details on clock rates with/without turbo.

[Manicdan]

the problem i have with Pi is how old and unoptimized it is

whats a good REAL USE single threaded test for today? besides games that only use 2-4 cores?

Unoptimized and old yes.

But I see Phenom II's @ 6.2GHz+ doing 10 seconds under LN2 on 1m

SB is doing 6 seconds at like 5.5.

If the BD design has improved that much, we will at least see some faster pi.

SuperPi wouldn't show us a thing. This is a completely new uArch that surely has alot of it's optimizations into code and instructions we can only dream that SuperPi has Intel nor AMD barely cares about x87 anymore and surely isn't optimizing their newest and hottest for SuperPi.

[informal]

Pi stresses the x87 logic inside the chip.That's is not representative of single thread performance. Single thread integer SIMD workloads are the most representative of single thread "IPC". BD should do well here too.

[chew*]

then use pifast as a comparison.

bottom line good single threaded performance means better over all performance in multithreaded as well since CPC is faster.

A chip for instance that has the same CPC as thuban would juat be thuban with 2 cores added, where as a chip that has much faster CPC would be able to match thuban in multithreaded with just 4 cores........

[CrazyNutz]

That is a very incorrect statement. PI will stress a single FPU unit on a single core, within a single thread. This is an exceptional way to compare FPU execution speed between AMD, and Intel.

Super pi uses ancient x87 instructions which are depreciated and obsolete since SSE2 launched. Super pi is in no way representative of FPU power of one single core.It just shows how fast can you do x87 math. Not to mention all those BD ES results are borked so move along.
BTW you quoted a post from January 2011,just FYI...

You have to be kidding, right?
I will correct informal here: Super Pi is not representative of any performance. The only thing that it does is shows how quickly(or better - slow) this app calculates Pi digits. That is all it does.

Great way to get yourself into discussion

[informal]

You are correct chew* .Don't forget that IPC(or CPC) is only one part of performance equation.There is working frequencies too . BD is supposed to be able to clock very high,so 2module/4 core Zambezi should not only be faster than Deneb QC at the same clock ,but should be able to work at much higher clocks from the start(think 4Ghz stock with Turbo on top of that). There are rumors of 3.5-3.8Ghz range for 95W 8 core parts .

[zalbard]

Now that would be one epic cruncher / air gaming chip...

[chew*]

Sounds good, atm AMD is tight lipped. I'm really not in the loop anymore for whatever reasons.

To bad we don't have clock sppeds for those numbers. I calculated awhile ago that 8 cores would put us on par with 980X as HT effeciency seems to drop on that platform the more cores they add.
