Ryzen 7 5800U laptop chip leaked, almost 40% improvement in single core performance against 4800U, could blow away all Intel mobility chips!

Ryzen 5800U is part of AMD's Cezanne family, will support 8 cores and 16 threads

AMD’s Ryzen 7 5800U flagship ‘Cezanne’ APU is turning out to be a big leap forward for laptops, as per the latest leaks coming out these days. The first benchmark of the Ryzen 7 5800U APU has leaked out. The benchmark was spotted by @leakbench within the Geekbench 5 database.

The leaked benchmark shows the AMD Ryzen 7 5800U which is going to be the top-tier chip in the Zen 3 powered Cezanne APU family. The Ryzen 7 5800U is powered by 8 cores, 16 threads, while sporting a base clock of 1.9 GHz, and a boost clock of 4.44 GHz. The clocks are a 100 MHz and 244 MHz bump respectively over the Ryzen 7 4800U which was based on the Zen 2 core architecture.

The biggest change we can see in the Ryzen 7 5800U is the cache. The 5800U now packs 16 MB of L3 cache compared to the 8 MB of L3 cache that’s available on Ryzen 7 4800U. The L2 cache is still at 4 MB or 512 KB per core. This helps in a reduced latency and faster inter-core interconnect bandwidth. The system was an internal AMD test platform and the system had 8 GB of DDR4 memory at a clock speed of 2666 MHz.

The Ryzen 7 5800U is coupled with a Vega GPU with 512 sp(stream processors) or 8cu(compute units) clocked at 2GHz. With the TDP set at 10W (25W cTDP), we should see some huge efficiency gains on the Zen 3 platform.

Looking at the benchmarks, we can see an almost 400 score lead on the single thread(1031 vs  1421) when comparing the 5800U with the 4800U on Geekbench 5. Similarly, we can see an improvement of 600 points in the multi thread score(5845 vs 6450) in the comparison. This proves that the single-threaded gains are quite significant and will put AMD in a leading position over Intel’s new Tiger Lake-U processors since the Ryzen 4000U family is already giving Intel a tough time, that they posted biased benchmarks to frame AMD, and failed really badly at it.
