We already know the approximate specs for the AMD Cezanne-H APUs, which will debut next month. AMD is preparing for the conference at the CES virtual fair 2021, during which the following units will be shown : AMD Ryzen 5 5600 H, Ryzen 7 5800 H, Ryzen 9 5900 HS and Ryzen 9 5900 HX. The latter is a new, flagship model designed for the most efficient laptops. New performance tests AMD Ryzen 9 5900 HX in GeekBench 5 have appeared on the network. The data reported by the benchmark shows that that the Cezanne-H system worked with a Turbo clock at 4.7 GHz, so also 100 MHz higher than the samples from a few weeks ago. The processor based on Zen 3 cores almost defeated one of the most efficient Intel desktop processors from the Comet Lake-S line in the new test.

The first test of the AMD Ryzen 9 processor 5900 HX from the Cezanne-H series APU laptop. The 4.7 GHz processor achieved a result comparable to that of the Intel Core i7 in the GeekBench test – 10700 K.

AMD Ryzen for laptops – we got to know the company’s detailed plans for years 2021 – 2022. First APU RDNA 2 already in 2021

The base clock of the AMD Ryzen 9 processor 5900 HX is 3.3 GHz, the same as in the predecessor in the form of Ryzen 9 4900 H. Here, however, newer and more refined Zen 3 cores were used. Interestingly, according to the reported tests, the Turbo clock was 4.7 GHz. It is therefore the highest clocked Ryzen ever to hit laptops. In addition, it will be the only Cezanne-H APU with an unlocked multiplier, and thus the possibility of additional OC. We hope that you will also be able to go crazy with your memories. Regular DDR4 Usage 3200 MHz CL 22 to such a unit is almost a crime.

In the single thread test, the results of the top APU Cezanne-H look quite promising. CPU obtained 1534 / 1547 points – this is a bit less than the Zen 3 desktop flagships from the Vermeer family, but also noticeably more than the Renoir systems. Ryzen 9 5900 HX did very well in the multi-thread test, scoring just over 9000 points. This is a noticeably higher result than both Ryzen 7 5800 H and Ryzen 9 4900 H. Interestingly, at the same time the top APU Cezanne almost equals the desktop Intel Core i7 – 10700 K. Here, the results depend heavily on specific platforms – sometimes the Comet Lake CPU performs lower, sometimes slightly higher. Anyway, this level of performance with incomparably lower energy consumption is even more impressive than what we have already seen on the occasion of APU Renoir. AMD Ryzen 9 5900 HX with a score of approx. 9000 points also beats the current Intel flagship in laptops in the form of Core i9 – 10980 HK – this chip usually does not exceed 8000 points in the multithreaded test.
