Leaked benchmark results for the AMD Ryzen 9 4900H paint a bleak picture: in a Dell system config, the flagship AMD mobile CPU is 10 percent slower than the lower-tier Ryzen 7 4800HS and can't hold a candle to the Comet Lake S i9-10980HK.

It's a Dell, their 2nd function is to act as a backup grill. Unfortunately their cooling solutions always seem to be some of the worst in the industry.
The heat density of 7nm and higher voltage result insuficient cooling as thermal module material conductivity below heat generated by die on a same given square area. Its better for amd to give better ipc on next apu

Which company's cooling are the best (and affordable at the same time)?
first guy-i found one benchmark result
second guy-what a disappointment
third guy-this manufacturer sucks
forth guy-no, that manufacturer sucks
..
not sure if it funny or sad.

What is your problem always arguing with everyone. You should not criticize other people. I understand you are at puberty, fighting with everyone but you should Relax. Go in the nature, do some exercise. Be friendly with others. Laugh more.
Waiting the review from notebokchat of amd 5600m gpu.
This benchmark seems to be clearly from a test sample only. It is operating at 3.0GHz base clock, but the final 4900H will run at 3.3GHz base clock.
While Dell 'could' theoretically nerf their own laptop CPU by 10%, that would make no sense at all. I'm sure they will have sufficient cooling to run it at its actual stock base speed.
AMD Ryzen 7 4800H + Radeon RX 5600M 6GB GDDR6
on a 17" laptop will be nice to own.
cheers

Dell doesn't have a good track record with cooling in general, or implementing AMD hw into a laptop.
In fact, previous Dell attempts were INTENTIONALLY nerfed to underperform because they paired earlier Zen mobile with single-channel RAM, low quality screens, slower performing SSD's and worse cooling - but still charged same or MORE money as much better equipped Intel versions.
Don't underestimate Dell's ability to nerf AMD's hw.
I'm not encouraged by this due to the fact that 4900H in early testing didn't show good performance (it was underperforming compared to 4800H), however, at the time I thought this was because it was an early engineering sample.
Its possible Dell has an adequate cooling in the laptop, but applied the thermal paste incorrectly (which would result in the CPU throttling and also hamper the GPU performance).
Or its possible Dell didn't give the laptop adequate cooling because they couldn't be bothered. It was mentioned before that Dell is 'experimenting' with AMD Zen 2 and Navi.
Either way, I certainly hope you are correct and that we will see better results when the unit is released (but its almost release date, so I'm a bit skeptical).
