AMD "Steamroller/Excavator" -info, speculations and experience

[xVeinx]

Understood, I was simply hoping that the performance ceiling (with changes) for the architecture would be closer to Haswell, and that they would be able to make some larger gains up front with SR to get performance at least to the level of Nehalem.

[Andi64]

10% is good. Look at Intel. SB vs IB around 3%, Haswell vs IB around max 5%. Is not much possible with x86 get higher. Only in software with new instruction support level (FMA, AVX)

Thanks for the comparison FlanK3r, very interesting. Could you run the test in sigle core at same clockspeed to make a direct comparison between the architectures? In multithreaded benchmarks the 7850K should have the advantage because of the changes in the scheduler.

Thanks again!

I did a quick calculation based on FlanK3r's results. Perf gain is 8.37%. To be honest, from all the leaks that has appeared before for AMD, I think we can trust these results.

((311/3.7) * 4.1 ) / 318
311 is multithreaded CB for Kaveri, 3.7 is Kaveri's clock speed, 4.1 is Richland clock speed and 318 is multithreaded CB for Richland.

First is 4100 MHz 6800K and second screenshot is stock A10-6800K with turbo.

news about kaveri on planet3dnow.de

[xVeinx]

A full spread of benchmarks are collected (originally from Baidu) by WCCFtech: benchmarks
There are some wild differences at points (6 second drop in Super Pi?), while gaming sees little improvement over 6800k.

[FlanK3r]

crazy is wprime too. But I tried BD fix for Richland and superpi is



So 3s difference against Kaveri

[StinkEye]

Seems as if there is maybe not much to look forward to then?

[xVeinx]

I think we'll need to see more real world benchmarks to know either way, but it looks like some nice improvement for a select few apps. Otherwise, its HSA/Mantle/TrueAudio that headline for this APU. More slides here: slides.

Oh, and pricing is at $173 now...

WccFtech forgot to mention like the original post has stated that the A10-7800 is just ENGINEERING sample

Kabini with Jaguar looks great, Im thinking. Vishera all next year? If AMD will be lucky, maybe at end of 2013 is SR possible. In worse case it could be sometimes in H1 2014. So...we will see maybe higher Vishera models in 2013.

Flank....need your advice, 1st of ALL HAPPY NEW YEAR...
I always remembered you talked about the Gskill TridentX is Super good with AMD.......just ordered this :

I wish they had 2x4 8gb but with the Cas7 in 1600mhz only have 2x8gb/
will 16Gb of ram 2 sticks slow me down vs 8gb?
thanks Flank

[i found nemo]

less populated slots = less latency and less stress on imc and thus better for overclocking.

very good news for me thanks, right now I have 4 slots at 2gb each 8 gb total......so now I will have 2 slots at cas7 vs my OCZ cas8 4 sticks......
needed a little kick of encouragement...thanks nemo

thanks good find......

for all testers, what need CPU-Z support for Kaveri. Fresh beta: http://www.cpuid.com/medias/files/so.../cpuz_1673.zip

thank you flank

[eagle101]

just got these tridentX gskills cas7 working good -2x8gigs very very fast and tight.......very impressive!

First is 4100 MHz 6800K and second screenshot is stock A10-6800K with turbo.

Nb is over clock on second picture it's also worth about 5% increase in single thread on cinebench 15.
what's the highest over clock on the nb that's stable ?

[FlanK3r]

no, its P-state. UNB clock in idle going down from 1800 MHz

[demonkevy666]

no, its P-state. UNB clock in idle going down from 1800 MHz

oh I see it's turbo is on too.

Hello! Where can i find drivers for my 7850k? Amd auto detect doenst work and there is no drivers anywhere

I cant use it igp. This is my personal review:
http://foro.noticias3d.com/vbulletin...d.php?t=421821

[FlanK3r]

download drivers from motherboard page (in chipset), its working.

[djohny]

It works! Thanks!

P.D is a heavy compute performance than trinity. Double in luxmark, tripple in sph fluid simulatiom and raytrace.
