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

not., again not...

there is clock to clock comparison tab at 4200MHz (turbo off). As you can see, average is only 3.42% better than Sandy-DT.

AND OC vs power consumption vs Cinebench performance against SB-DT

PS: the difference between Zambezi and Vishera could be simillary as between SB-DT and IB-DT (so about 3-5% average clock to clock)

Those IB numbers are really bad because of INTC screwing up the TIM. When u remove the IHS and use a good TIM, those #s come way down on CPU core and temps. Anyone that OC's a IB pulls the IHS now. IB is much closer than the chart shows with proper TIM. When INTC gets those parts back to being soldered, it will be a much better CPU comparison to SB. The core temps will drop ~25degC with good TIM/soldered IHS. There are a few threads in the INTC forum that chronicle this very well. INTC will eventually fix this issue.

So bring this back around, that comparison is not really that valid, as the IB core is really much better than the chart shows.
