The Ryzen 9 5900HX AMD is the processor architecture notebook Cezanne-H, which uses the new Zen 3. The APU cores appeared in Geekbench showing a very interesting performance.
The AMD Ryzen 9 5900HX will offer 8 cores and 16 threads with a 16MB L3 cache and 4MB L2 cache. The base clock will be 3.30 GHz and the boost clock is 4.70 GHz. This speed is shown to be achieved in all cores. The integrated GPU is a Vega and it looks like it can be overclocked.
For testing purposes, an ASUS ROG Zephyrus Duo 15 SE (GX551QS) laptop was used. ASUS is going to offer this same laptop with a Tiger Lake-H processor. The notebook has 32GB of DDR4-3200 RAM and appears to have RTX 30 graphics. This notebook model would be unveiled during CES 2021.
Performance on GeekBench
The Ryzen 9 5900HX scored 1534 points in single-core tests and 9015 points in multi-core tests. Compared to the previous Ryzen 7 4800H, the Ryzen 9 5900HX is 41% faster in single-core tests and 36% faster in multi-core tests. This is a huge step forward from one generation to the next.
When compared to desktop CPUs like the Ryzen 7 3800X or the Intel Core i7-10700K, AMD’s new piece for laptops leaves them behind in multi-core tests. It ends up being 19% faster than the Ryzen 7 3800X and 14% faster than the Core i7-10700K. This is a small feat, as these chips are designed to run at a much higher TDP.
The first laptops with the new Zen 3 APUs will arrive in early 2021. We will keep you posted.
