Brutal ST performance as expected from GB5 leaks. One has to wonder how well it would score with desktop class memory setup.
Yea, single thread performance is outstanding. Too bad they dont have more cores in mobile (I know it is supposed to be coming), and the same sort of IPC for the desktop.Brutal ST performance as expected from GB5 leaks. One has to wonder how well it would score with desktop class memory setup.
Interesting that Tigerlake and Renoir when both limited to 15W perform about the same with Renoir seeming to have the edge
It had LPDDR4X 4266, that's pretty good.

Which tests? At pcworld Tigerlake PL1 15W win 3 of 4 games against 4800U PL1 38W.

It's a same Lenovo Yoga Slim 7 as in Anandtech review, as seen in Anandtech it's max turbo power is 38W and sustained power level 15W.
So it could have used 38W depending on how long their gaming test lasted: https://www.notebookcheck.com/fileadmin/Notebooks/Lenovo/Yoga_Slim_7-14ARE/metrawit.png
Anandtech blindly assumes it's running at 15W which is bogus.

It's 15W tdp chip compared to 15W tdp chip,
That's a bunch of nonsense.
The Ryzen 7 4800U is an Absolute Monster: Lenovo Yoga Slim 7 14 Laptop Review
After facing a few delays, AMD's premier Ryzen 7 4800U is finally starting to hit store shelves. Results are insane for a 14-inch subnotebook to the point where it'd be tough to recommend an Intel counterpart when given the same price.www.notebookcheck.net
Load Average numbers are higher on the Yoga Slim 7 than it is on the XPS 13 7390 by 6W, and that system is using 46W PL1 on AC and 25W PL1 on DC.
15W Icelake systems like the Acer uses only 27W on load. Computerbase.de also shows testing of the Slim 7 on both 15W and 25W.
@Hitman928 I know some of the AMD systems do weird things with power consumption.
For example:

Both Load Average and Load Maximum numbers are significantly lower than Witcher 3 Ultra numbers. It's like systems can specifically boost to 25W in gaming but stay at 15W for synthetic and CPU workloads.
Says the guy with the 2 year old account. 🤔Well I see the low post count naysayers are out.
Anandtech's power/turbo test shows it dropping to 15W long term. Perhaps Anandtech specifically set it to 15W? I guess we could ask @Ryan Smith for confirmation.

Most people posting here don’t understand that power != TDP and why a chip capped to 15W is slower than the same chip that allows momentary spikes to 30-50W.

There is like a ~50pt difference between the 4800U and 4900HS is Geekbench 5 ST integer score, which means that there is no more headroom left in Renoir even if you double the power limits(in tests the U-series are limited to 30W and H/HS often reach 60W or more). Tigerlake on the other hand scores ~35% better in GB5 ST integer while pulling 50W. Granted that Intel is still not up to the mark in perf/watt, but it's ST perf is still very impressive.
@Hitman928 That's not SoC power, but GPU power.
You do have a point about it being peak power.
Nevertheless, you can see a true 15W system uses ~30W(plus or minus 10%). The Slim 7 cannot be a 15W device.
There's also no point of a battery life test on a reference system. I remember when they used to do this. The Sandy Bridge 45W system with the iGPU had great battery life.
In reality, barely anyone used the iGPU-only setup and the battery would huff and puff to get 2.5 hours, which is less than half of the 6 hours the reference system got. Actually the U systems rarely reached 6 hours.
