AMD Ryzen 7 5800U 'Zen 3' CPU Based Laptop Tested, 15W Chip Delivers Single-Core Performance On Par With Intel's Top Desktop CPUs

We have been talking about the high-performance Cezanne CPUs based on the Zen 3 compages for a while now but it's time to take a expect at the Ryzen 5000 U-series chips. And so for that purpose, we are taking a look at the latest benchmarks of an AMD Ryzen 7 5800U based laptop which has been posted by Uniko's hardware.

AMD Ryzen 7 5800U 'Cezanne-H' CPU With 8 Zen 3 Cores Tested, 15W Chip Faster Than About Intel tenth Gen Cadre i7 Desktop CPUs

The AMD Ryzen seven 5800U is part of the Cezanne-U lineup which is aimed at mainstream and depression-power notebook designs. As such, it will characteristic lower clock speeds but retain more often than not the same configuration as the Cezanne-H role. Coming directly to the specifications, the Ryzen vii 5800U is going to feature viii cores and 16 threads forth with 16 MB of L3 cache and 4 MB of L2 cache. The clocks for the chip are set at 2.00 GHz base and 4.40 GHz boost.

AMD Ryzen 5000 APU Lineup (Preliminary Specs):

APU Name	APU Family	Architecture	Process	Cores / Threads	Base Clock	Boost Clock	L3 Cache	Graphics	GPU Clock	TDP
Ryzen 9 5900HX	Cezanne H	Zen 3	7nm	viii / sixteen	3.30 GHz	iv.70 GHz	16 MB	8 CUs (512 SP)	TBD	35-45W
Ryzen ix 5900H	Cezanne H	Zen 3	7nm	8 / 16	3.30 GHz	4.65 GHz	16 MB	eight CUs (512 SP)	TBD	35-45W
Ryzen 7 5800H	Cezanne H	Zen 3	7nm	8 / sixteen	three.twenty GHz	TBD	16 MB	viii CUs (512 SP)	~2000 MHz	35-45W
Ryzen 9 5900HS	Cezanne H	Zen three	7nm	viii / 16	three.10 GHz	4.50 GHz	16 MB	TBD	TBD	35-45W
Ryzen v 5600H	Cezanne H	Zen 3	7nm	6 / 12	3.x GHz	4.10 GHz	eight MB	TBD	TBD	35-45W
Ryzen vii 5800U	Cezanne U	Zen 3	7nm	eight / 16	2.00 GHz	4.xl GHz	16 MB	eight CUs (512 SP)	2000 MHz	10-25W
Ryzen 7 5700U	Lucienne U	Zen ii	7nm	8 / sixteen	i.eighty GHz	4.30 GHz	8 MB	8 CUs (512 SP)	1900 MHz	10-25W
Ryzen v 5600U	Cezanne U	Zen iii	7nm	6 / 12	2.30 GHz	4.30 GHz	12 MB	vii CUs (448 SP)	1800 MHz	x-25W
Ryzen 5 5500U	Lucienne U	Zen ii	7nm	half-dozen / 12	2.10 GHz	iv.00 GHz	8 MB	seven CUs (448 SP)	1800 MHz	x-25W
Ryzen 3 5400U	Cezanne U	Zen 3	7nm	4 / 8	ii.60 GHz	4.00 GHz	8 MB	half dozen CUs (384 SP)	1600 MHz	10-25W
Ryzen three 5300U	Lucienne U	Zen 2	7nm	4 / 8	ii.60 GHz	three.85 GHz	4 MB	six CU (384 SP)	1500 MHz	10-25W

Since this is a 15W design, information technology cannot be compared to the Cezanne-H 35W parts which offer much higher and stable clock speeds. Uniko's numbers come from its ain sources and based effectually early laptop designs then while the numbers are definitely not final, they are worth taking a expect at.

For functioning, we have three benchmarks that were posted. These include CPU-z, Cinebench R20, and Cinebench R23. In CPU-z, the AMD Ryzen 7 5800U scores 592 points in unmarried and 3812 points in multi-core tests. In Cinebench R23, the fleck scores 509 points in single and 3614 points within the multi-core exam. In Cinebench R20, the bit scores 1311 points in unmarried and 9326 points in the multi-core test.

One matter that is immediately noticeable is that the single-cadre performance sees a major jump only the multi-threaded performance merely isn't that peachy. This could be due to several reasons with the early laptop design being i of them. It is possible that the multi-threading for this specific flake is not operating properly. Withal, Uniko reports that the same source provided him some results of an AMD Ryzen 7 4800U running on a similar laptop configuration and that scored 479 points in the unmarried-cadre and 2836 points in the multi-core exam in Cinebench R20. This represents a pb of half dozen.2% in single and 27.iv% in the multi-core tests. Just for comparison'southward sake, we will just continue the Ryzen vii 5800U multi-thread numbers out for now. You can come across beneath how the numbers stack up in CPU-z beneath:

As you can see, the single-cadre operation is right there with Intel'south top dogs in the desktop CPU segment. That is a fantastic showcase of merely how skillful AMD's single-cadre pb has gone up with its Zen 3 cadre architecture. And the most mind-boggling function is that this scrap has a TDP of 15W which goes up to 25W at max while the Intel Desktop CPUs are rated at 125W but go all the way up to 250 Watts. Of course, the bit won't clock as well and won't be offer the same amount of multi-core performance just in the end, just getting close to these desktop parts is a feat on its own.
