That figure appears to come from an AMD chart focusing on one projection, "Floating Point performance".Originally Posted by -Sweeper_
looks like they wont talk about clock speeds
150+% of the performance with 133% the number of cores
thats 12,7+% more performance per core, something easily achievable with higher clocks (magny cours works at a modest 2.3ghz)
It shows MC at "28", and Interlagos at "43" (at max, the line fades starting around 40). 43% to 53% improvement.
But given that Interlagos/BD has AVX (including FMA), this really isn't all that impressive, is it?
"Integer performance" on the same chart goes from "29" to "36-38.5" (from start fade to end fade)
That's a 24% to 33% improvement for 33% more cores.
Hmmm, doesn't really look like much single-threaded improvement there.
In sum:
From -7% to 0% performance loss per core on "Integer"
From 7.5% to 15% performance gain per core on "Floating point" -- and that's with AVX!
Can you imagine the outcry from saaya were SB to compare to Westmere in such a way? I can hear it now... "Epic Fail!!!!!111"
Other than AVX helping FP perf, somewhat less than expected, I don't see any single-threaded gains from MC --> BD, not based on these performance projections, anyhow.
