The TDP of the Cherry Trail-T X7-Z8750 is 2.17W. That's less than HALF the m3. If Intel hadn't cancelled their ULP sub-3W Atom lineup, the successor to Cherry Trail-T would have been competitive with KBL-Y. That's why they cancelled it... lower profit margin and hurts sales of m3. Now if MS releases a 10" Surface they have to either use SD or m3. SD will get there eventually (plus more software will be compiled for both architectures) but right now m3 is the safe route. To be fair to the m3 it has a lot more GPU grunt than the Atom-T or it's murdered successor, but that's really just a fight between two cripples. All the x86 SoCs below the 12W Ryzen Mobile quad-cores have GARBAGE graphics. That's one area where the top ARM chips shine, they have halfway decent graphics considering their dimunitive die size and low TDP.
That stretch goal is exactly why I was looking at it.
Thanks for reporting this chart, it's nice to read the benefits considering the new stretchgoal of this campaign:
thank you for replying a comment from almost exactly 1 year ago. Yes, as of today I already know that for a long time. Thank you anyways
The M3 beats the X7 at everything - surprisingly, even at multi-core benchmarks. The only downside of the M3 is slightly higher power consumption (4.5W vs. 4W)
Need tests on these 2 CPU, they come on tablets with the same price range, i hard to know which is better
