AMD Ryzen 7 5800U is delivering tremendous single-core performance

Thanks to recently leaked CPU-Z and Cinebench benchmarks the AMD Ryzen 7 5800U has been showing some brilliant results. Single-core and single-thread scores were incredible, to the point that the laptop Ryzen 7 5800U could even outscore a desktop Intel Core i9-10900K. However, there seemed to be a case with the Cezanne APU’s multi-core executions.


The AMD Ryzen 7 5800U is an approaching Ryzen 5000 series mobile APU based on Zen 3 architecture, it is classed as a Cezanne chip and should offer greater performance than its fellow Lucienne Zen 2 parts (that are a Renoir Refresh). A representation has appeared on both CPU-Z and Cinebench, as noted by Uniko’s Hardware (in Chinese; via VideoCardz). The single-thread and single-core results achieved by the Ryzen 7 5800 will have shoppers exclaiming for a thin and light laptop featuring the processor, but the multi-core results were hindered by some unknown issue.

The Cinebench single-core outcomes for the Ryzen 7 5800U show a small performance increase over the Ryzen 7 4800U: R20 +5.56%; R23 +6.15% (against median scores). The 8-core Ryzen 5000 processor clocks at 2.0 GHz to 4.4 GHz and has an L3 cache of 16 MB compared to the Renoir part with 1.8 GHz to 4.2 GHz and 8 MB Level 3 cache. However, the multi-core outcomes for the AMD Ryzen 7 5800U are a mixed bag when correlated to the Ryzen 7 4800U (R20: +10.88%; R23: -4.47%), with VideoCardz opining that the tested laptop is artificially restricting the Zen 3 chip or there is an SMT issue with this type.

The multithread result for the Ryzen 7 5800U in CPU-Z enhances the possibility that the chip is being limited and will likely generate better results in later benchmarks, as it only scores 3,812 points here, which is a poor result for a 16-thread Ryzen processor. But the single-thread score of 592 points puts the 25 W part ahead of the 125 W Intel Core i9-10900K that has 584 points in CPU-Z’s performance chart. With benchmark results like that, a thin and light laptop sporting the Ryzen 7 5800U could offer the kind of feat that was previously limited to desktop PCs. It also puts a big dent in Team Blue’s anticipated single-thread/single-core superiority.
