Not correct (I see it has been fixed in the article) it will use GloFo's 28nm bulk process.Looks like 28nm TSMC according to anand's article
Be serious please. Bulldozer is faster than K8,it's around the level of first gen K10 core (65nm Barcelona). This core is ~10-15% faster than K8 in integer and 1.5-2x faster in SSE workloads. In FP stuff Bulldozer is just crushing K8 (not hard since K8 has 64bit FPU).Steamroller: back to K8 level of performance? Lol. We can only hope.
Last I heard, Piledriver was the last AM3+ processor.Sorry if I missed in in the article, but does anyone know if this is an AM3+ part, or a new socket? I got a long useful life out of my AM2+ (still on it in fact), so I'm just curious.
It says the same throughput at lower power/area.On topic of SR core,integer execution looks to be having the major perf. boost while FP coprocessor is sort of a letdown. It's the same old FP unit we have in BD and PD. AMD even states they cut it down further to save power and area (they apparently axed one MMX pipe). Unless they somehow found a way to make that same old FP unit perform 50% better (if it had a major design bug?) then they will stand no chance against Haswell. Haswell will add FMA execution support and then AMD will need 4x the "cores" of intel equivalent Haswell server chip to match its FP throughput . It's obvious why this is not realistic(16 modules SR server chip is not gonna happen).
Actually I think steam roller will be released early. Hopefully vishera is cancelled all together and they release steam roller/frontloader in January. That would be nice.
^ The first thing that came to my mind when i read the article.
Does steamroller have AVX2?
Is there a Front Loader?
I thought it went
Bulldozer
Steam Roller
Pile Driver
Excavator
BD
PD
SR
EX
The frontloader comment refers to the frontloader tractor pictured on the steamroller slide. Alas, if CPU design doesn't work out for them it appears they don't have much of a future in construction either...
when i read the article, it says that FPU would lose peak frequency...
yet the cpu is made to reach high performance
AVX-2 ? probably not...way too soon.....maybe in excavator
