Then i don't see a problem with 16C... I mean we have plenty of headroom for more W. Even if AVX512 uses 40% more power ~ 90W for CPu die x2 = ~ 180W + 55W +10W for I/OThat s about 100% sure, in the range of 15% excess power out of the 65W or so it consumed in the demo.
The 75W stated by AT is the estimated delta measured at the main assuming that system idle power was 55W, actually the delta should be a little higher at 84W, wich is 65W at the SoC level.
15% higher score than a 2700X at 65W is perfectly in line with 2x the perf/watt at isofrequency but not isoperf, the 15% delta in perf imply 0.5 x 1.15 = 0.575x the power, wich is exactly the ratio between this SKU and a 2700X, so much that this point to the test being done at 4GHz wich is the 2700X all core turbo in CB.
FTR the numbers stated by AMD imply that power increase by at least 16% from 4 to 4.2GHz, if it were such a frequency clocking the Zen 2 there would be no way that it could be at only 65W when we add an excess voltage, 15% higher throughput and an I/O still in 14nm.
If I/O is low latency (high freq) then probably it will use more power ~20W which means 55W for CPU * 1,4 for AVX 512 = 77W * 2 = 154W (more heat more power + x1,05) + ~ 25-30W for Uncore / iF
So basically we have +15W as ~i9 9900K running AVX2 at 4,3GHz+LLC4GHz?
