Any estimates for Cherrytrail?

Cherrytrail has 4x the EU count of Bay Trail, and the additional enhancements of Gen8 graphics - but it likely doesn't quadruple everything. Unconstrained, I would expect maybe 3x better performance than Bay Trail, and at constrained power, it should be in the 2-2.5x range. Haswell 15W is a bit of an upper bound. Cherrytrail has 16 instead of Haswell's 20 EU's, but Gen8 increased the throughput of the texture samplers and other fixed function units. So it may end up performing close to it, (though at potentially half the 15W that Haswell dissipated for that performance).

The fastest Bay Trail submission gets 9.3 FPS in Manhattan, and 18.6 FPS in T-Rex. As I said in my previous post, the Haswell 15W submission gets 30.4 FPS in Manhattan, and 61.9 FPS in T-Rex.

Projected Cherrytrail unconstrained (~8W): 25-30+ FPS, 55-60+ FPS
Projected Cherrytrail at constrained TDP (~4W): ~20+ FPS, ~40-45+ FPS

The pluses are there, just because I feel the numbers may be a bit conservative. Hopefully Intel surprises me.

It should edge out Apple A8 in a tablet design, and maybe edge out Tegra K1 in larger designs (laptops, all-in-ones, etc). Intel's problem is that Cherrytrail seems to have slipped into 2015. It would have been a killer design today, but Intel clearly prioritized Broadwell for the 14nm ramp. I hope we see Cherrytrail devices by CES, but it may not be high volume until later in Q1, according to this article.
