Multiple benchmarks have already shown that the Ryzen 7 4800U is a more than capable 15 W APU, but what about its lesser sibling, the Ryzen 7 4700U? Well, Phoronix has put the eight-core chip against a Core i7-1065G7 in an exhaustive set of benchmarks, and it makes for bleak reading if you are team Intel.

Ryzen 7 4700U came out to being 72% faster than the i7-1065G7 and 32% faster in games according to author.
The ideapad 5 is a pretty decent laptop, also we have choice of display with 100% srgb for 50€
It's a shave they increased the prices and no more 4600u or 4800u
We really need 4900U+ 3070/3080/23.

...on a performance-per-Watt basis throughout different tests we found it [Ryzen 7 4700U] generally even ahead of the Ice Lake laptop.
there is no "even ahead", ice lake laptop finished last.
this testing is absolute mess
they measured processor performance in many tests, but calculated energy efficiency with only one selected test. and it was not the efficiency of the processor, but the efficiency of the laptop!
..different ubuntu kernel, why?..
..5 participants in one graph, 3 in another, is not a good sign.. no page with testing methods and hardware configurations, instead they put a picture with this kind of stuff on the 7th page, and you have to open it in a new tab to see something.
these guys are not too good in testing, and especially in the writing.

ideapad 5 cpu lineup is (cores/threads) : 4/4-6/6-8/8
hard to make a smoother lineup.
you want all dozen of models? no, go away.
After seeing the first graph and looking at power consumption, I am going to sit back, and wait for real world usages review first.
I have a feeling that, while more powerful, the energy management from AMD is still not there. And in laptops, it is not the one who arrives first, but rather who last longer while keeping perfomance what matters. If you want power, you better get a desktop then.
I had the Ideapad 5 briefly and is idle power drain witth Firefox open is barely 5W, better than the Ice Lake on my Dell
