[xbitlabs] AMD: We Are On Track With Steamroller Micro-Architecture in 2013. - Page 33  

post #321 of 718
it's 30% Steamroller over Bulldozer, not Piledriver..

Thread Starter 
If we do see a 45% improvement with SR then I guess it's safe to say that ivy bridge is in serious trouble. It's still hard to believe that SR could provide a 45% improvement.

Piledriver is exactly the same as Bulldozer, in respect to what is being changed between Bulldozer and Steamroller. Piledriver still uses 1 decode for both integer units and doesn't have a dedicated MMX unit. The cache sizes are the same as Bulldozer. Etc etc etc.

Edit: Also, Steamroller uses a shorter pipeline length for FPU, which usually indicates higher IPC.

All I care about are hard factual performance numbers. Unless you can show me an authentic benchmark, I will be waiting for reviews. mkbai thumb.gif

never gonna happen and Ivy is not in any trouble at all..
and even if it comes close to those numbers (which it won't) the performance will still not be Ivy levels, closer yes.

post #327 of 718
the stronger the single then the stronger the multiples too, is it not logical.?
stronger, better cores in general.. thumb.gif

A lot of the changes increase the size of internal buffers or the throughput of certain paths inside the core. This is clearly an attempt to get rid of certain bottlenecks in the design. One of the interesting changes is that with Steamroller, each core gets it's own integer decoder, which should improve performance if both cores of a modules are fully loaded. The reduced floating point pipeline length should lead to an increase in floating point IPC, as the instruction latency is reduced by 25%. On the slide you can see the projected performance implications.

3 instructions vs 4 instructions

Really? Because if single threaded performance/IPC is greatly improved from Bulldozer/PD then it will should perform much better on the whole. Not sure if serious.

he's in denial...

this performance increase is coming from whom, that's right it's coming from AMD.. rolleyes.gif
when some products drop and we see some testing from reliable sources, I'll take note.
I've been down this road before with false promises, false advertising from AMD.
