It was obfuscated. Yes, that is correct.
Obfuscated or not, Dullard is right. The product will have the final word anyways.
10nm SF is a good gain
plus Icelake sucks in frequencies. What's so hard to believe? We know from products that sucking in frequencies are likely true for all frequency levels because Icelake sometimes regresses in battery life compared to the predecessor.
NBC tests show 1065G7, the top Icelake part clocks at 2.4-2.6GHz using 25W running Prime95 stress test, and 1.8-2GHz at 15W. The Cometlake 10510U can clock from 2.7-2.9GHz at 25W. At 15W, 10510U is almost at 1065G7 25W level clocking at 2.3GHz.
It's clearly frequency, since Sunny Cove goes to 3.9GHz in the 1065G7 product and the graph is slightly under 4GHz.
Even Willow Cove's graph is based on a real product as we know the Turbo will be in the 4.7GHz range. That's exactly what straight line up extrapolation from Sunny Cove gives us.
Call it coincidence or not, but the second graph labeled "Increased Power Efficiency" is at 3.6GHz, which is the Turbo frequency for one of the leaked -Y variants. Along with slightly improved uarch, it essentially means same performance as the 25W Icelake but at 10-12W, or fanless envelopes.
