Which Intel processor is better (notebook)?

Which Intel processor of the 10 Gen. Provides more power / graphics performance for a notebook? The i7-10510U or the i7-1065G7?

1.3 GHz on the G7 sounds very slow, because the 10510U will be faster.

However, I advise you to read the notebook model, which voltage is allowed for continuous load maximum. For many, that's 11 volts, which inevitably causes an i7 to go down so much under continuous load that you can buy an i5 as well.

Clearly the 1065G7: latest generation, faster, more economical (since already built in 10 nm technology), better graphics chip (Iris Plus Grafik 940)

So GHz does not always mean something.

Just looked at benchmarks. Do not take anything. Sometimes the G7 is faster, sometimes the other. But here we're talking about a scatter of a few percent. We will not notice a difference.

Not since the Pentium successor anymore

The Core i7-10510u looks very much like a redefined Mobile Core from Intel's 8000/9000 Series, which still had a 14 nm structure width and also had an (older) Intel UHD 6xx graphics solution.

By contrast, the i7-1065G7 is already being produced in the new 10 nm process and also has a (mathematically) more powerful Intel Iris Plus 640 or 650 graphics (depending on the preconfigured TDP).

The "configurable TDP" makes a direct comparison of these two processors, unfortunately, not so easy, because here factory / from the notebook manufacturer each values between 10/12 to max. 25 watts (fixed) are adjustable. In addition, the TDP always refers to CPU and graphics cores together.

Each on its own ("synthetic") ping, the i7-1065G7 would despite higher clock rates both in the field of CPU cores a higher IPC (computing power per core & Mhz), than theoretically also at the same time a significantly higher graphics performance due to higher number of execution -Units (48 vs. 24 EUs). At the same time, the newer G7 in notebooks now supports (up to) LPDDR4-3733 instead of previously only LPDDR3-2133 on the 10510u.

Computationally speaks almost everything for the G7 - but the whole thing must be considered in practice because of the energy distribution within the predefined TDP budget just combined from CPU cores + GPU - unit equally, since the available energy budget then corresponding to the possible turbo Clock rates of the CPU cores & GPU unit alike.

But I go very strongly from an at least noticeably higher overall performance per watt and Mhz (CPU part) in the G7, if both processors would have to make do with the same TDP budget.
