Mobile processors from AMD’s upcoming Ryzen notebook family 5000 U can be found in Geekbench’s online benchmark database. The top model Ryzen 7 5800 U (code name Cezanne) is there with 16 MByte level 3 cache noted – twice as much as in the previous Ryzen 7 4800 U. The specification of a single L3 cache pool confirms that it is the first mobile Zen 3 offshoot. In Zen 2, the cache is divided by two CPU core clusters.

Combining them into one large core complex helps with single-threading performance, because a single CPU core can access the entire L3 cache. Further architecture improvements and higher clock frequencies (stable 4.4 GHz) bring the Ryzen 7 5800 U in Geekbench a single threading result of 1421 Points – about 23 Percent more than the Ryzen 7 4800 U manages in a Lenovo IdeaPad 5. The 5000 he test system ran with DDR4 – 2666 – instead of DDR4 – 3200 – memory or even faster LPDDR4X-RAM, so that there would still be potential for more performance.

6450 Points in the multithreading benchmark are meanwhile below the result of a good Ryzen-7 – 4800 U notebooks, which could be due to insufficient cooling or reduced power consumption.

Ryzen 7 5700 with Zen 2 architecture An entry for Ryzen 7 5700 U in Geekbench coincides with rumors that AMD is in the 5000 U series Zen 3 processors (Cezanne) with a Zen-2-Refresh (Lucienne). According to the data, the Ryzen 7 5700 U corresponds to a higher clocked Ryzen 7 4800 U with a good 4.3 instead of 4.2 GHz boost, but still 2 × 4 MB L3 cache. The single threading result increases accordingly (1192 points); However, the multithreading rating is too low here (6284 points).

The final mobile processors from the Cezanne family would have to run a bit faster in order to be able to compete with Intel’s current Tiger Lake CPUs in terms of single threading performance. The Core i7 – 1185 G7 almost manages 1421 Points in Geekbench – but lags behind in multitheading benchmarks because of its four processing cores (just 5000 Points in Geekbench at 15 Watt TDP). Apple’s M1 processor from the new ARM MacBook sets itself apart at least in the Geekbench from AMD and Intel: A performance core creates 1740 Points, all eight together just under 7700.
