That's interesting. I'm surprised that the 5Y70 in this tablet performs so much better than the i5 or i7 (?) in Anantech's Surface Pro 3.
Last week I've read that the 5Y70 is supposed to run approx. 10 % slower compared to the i5/i7 U-series while consuming only a third of the energy.
I would like to see if it is only better in these two benchmarks or if it faster in general.
Hmmmm.... I wonder why....MSFT did not sample any reviewers an i7.
at launch they probably knew the fan blew like mad and would get lousy reviews. they seem to have fixed that problem in this week's firmware update, but it's 5 weeks lateHmmmm.... I wonder why....
I believe the 40% number is an in family figure meaning the Y series sees a 40% increase and the u series sees a 40% increase but there's not a direct correlation between Y & U thus you get a 10% increase over a Haswell U but also a drop in TDP from 15W to 4.5w. or 70% power reduction with 10% performance gain.Seems to be slightly better - a sunspider test is hardly a good representation of "performance" IMO (at least in the way I use the SP).
"Yes, it's unlikely it was 4.5W since most Intel CPUs can run at 125% or more of their official TDP for some time. Also as others noted it is way too fast to be true on SunSpider, so this is obviously due to the usual browser differences and tricks (unlike the other results the 5Y50 scores are provided by Intel). People will be quite disappointed when the actual CPUs become available as they of course won't be twice as fast as Surface Pro!"
The 3D mark test is a 10% difference. I would say that's underwhelming for a gfx upgrade that was supposedly 40% better.
To play devil's advocate the SP4 will definitely be better than the SP3 though.
