AMD "Piledriver" refresh of Zambezi - info, speculations, test, fans

[informal]

Mechanical Man I don't think so, because instead of L3 cache they have a big IGP.

informal FPU in BD should be working at full speed, after all FX 4100 and Llano 3850 have the same performance in Sandra.

Well if you read what dresdenboy said,some units at least seem to be half clocked. But we just don't know as of now since AMD is not saying anything. Officially, according to them, all is fine... But we know all is not fine since as JF-AMD said,back in 2010 before tape out ,original goal was higher IPC. Easy explanation is half clocked units within the module(whether it's L2,FPU etc.).

As for FX4100,sandra is synthetic benchmark. In real world FP intensive workloads FX4100 with Turbo is usually behind or just on par with 2.9Ghz Llano.

What I think would be perfect PD scenario for AMD is: ~5-10% higher IPC and 4-4.2Ghz base clock for top end model. This would put it in 16-28% range over 8150 ,a pretty good spot (over 2600/2700K on average and very close to 980/990x).
