Title: Microsoft Surface Pro 7 Core i7 performance can throttle by almost 30 percent over time
Post by: Redaktion on February 22, 2020, 06:37:56
Don't be fooled into believing that the Core i7-1065G7 CPU in the latest Surface Pro 7 tablet can perform roughly the same as the Core i7-1065G7 in a "proper" Ultrabook. The tablet version of the processor can be around 22 percent slower than similarly equipped 15-inch Surface Laptop 3.

From the Original article:
Quote"Please note that CPU performance was severely throttled on battery. The multi-core score dropped from 783 to just 262 points, and the single-core score to a meager 49 points. Average clock speeds were around 2.4 to 2.5 GHz."
This is bad, very bad!.
After all this is a tablet and this is the performance users will get 90% of the time until they dock it.
this just shows how bad the 10nm processes is, the CPU architecture is great but the bad 10nm processes kill is, it's not real 15W part and it needs a lot of juice to push the clocks above 2Ghz - this is the bad processes fault.
So it's better to save the $$ and get i3/i5 if you must buy it now or wait for proper ultra book CPU like Ryzen 4800U.

One more argument against buying the SP vs. XPS13...but so far XPS13's digitizer proves good as useless with its insane diagonal jitter or overstabilized lag.

What about the surface laptop 3 13.5" ? is a review coming soon of that aswell?

Would like to see how it fares compared to the 15" Intel variant in terms of throttling, speakers, battery life, noise/thermals and etc. Is it worth it paying the extra $300 or not?

Looking to buy a device with absolute best performing on battery Ice Lake configuration for the money. Ideally, would prefer Tiger Lake but can't wait that long and Renoir APU's -- I don't have much faith in AMD's driver support after the whole Navi / Vega fiasco's.

Does the same hold true of the i5 variant?

So is there a way to get the full speed, (is it at least full throttle when plugged in?) or did I waste hundreds or dollars? Can it be "overclocked" to be up to its potential?

Do also remember this is workload dependent, if you are not maxing the CPU for extended periods, it will likely boost and drop and stay within thermal limits. Good information to have if you need to be rendering etc though.
