I'm skeptical about the model names, seems too busy, plus the 6 core i7 having a 300 mhz less turbo than the quad i7?
In theory adding 2 extra cores adds nothing else, just the two cores. In practice, higher core parts have higher idle power. So during the transition process it makes sense to sell both, with the lower core version for higher clocks.
IOn top of that 10nm is (up to half the power?) and Gen11 cores are reportedly smaller than Gen9.5 (indicating a 1:1 power ratio per core isn't likely), so overall we should expect the IGP power budget to remain mostly stationary relative to previous gen.
Half the power with new process alone is doubtful. In the 65/45nm days they claimed 30% reduction in power with a new process. I can't believe that its any better now. If anything, it'll be less. While the EUs are 25% smaller ISO-process, there's also 2.7x as much. Even reaching an identical level will require a big leap. Perhaps that's what Gen 11 is, but let's see it first.
The base clocks in that table look like Y class to me, while the boost clocks are U class, although I was expecting less than 20% drop in fmax. This contradiction alone make me question the veracity of the leak.
The boost clocks are also Y class. The U chips now clock close to 5GHz.
I don't know, I'm not making any conclusions, but it seems to fit with the earlier leaked roadmaps. Of course, much earlier than that though, we had leaks for 4-core Y ICL.
If we assume Y, then why are they segmenting the GPU on a 5-7W chip? It probably makes no difference anyway.
It probably doesn't matter that much for CPU performance, as it can clock to whatever it wants. Why is the base so low if its a U chip though?
Raises more questions than answers. Though there's another possibility. Think of Broadwell-C. A GPU-focused part with lower CPU performance. Doesn't cannibalize 4790K or Skylake.
I said the customer preference will be very skewed towards ICL parts if the chip is very advantageous over Comet Lake parts. Perhaps Comet Lake is for dGPU parts and Icelake is for iGPU.
