In less than a month, AMD will officially present new laptop processors. I am talking about the Ryzen series 5000, which will include low-voltage Cezanne-U and Lucienne-U units, as well as full-voltage Cezanne-H systems. Processors from the Cezanne family will use Zen 3 cores, which have been significantly improved mainly in terms of single-threaded performance. We already know exactly what processors the manufacturer is preparing, both for the Lucienne and Cezanne series. We expect not only the continuation of the idea for the Cezanne-H processor line, which will have a reduced TDP to 35 W (so-called HS) . A new addition will be the top Ryzen 9 5900 HX, characterized by, among others unlocked multiplier. Meanwhile, Acer is quietly working on a new version of the Nitro 5 laptop, which will use an 8-core and 16 – a threaded AMD chip Ryzen 7 5800 H.

A new version of the Acer Nitro 5 laptop with AMD Ryzen 7 processor has been tested in the GeekBench database 5800 H. The Cezanne-H APU is 35% better than its predecessor in the single thread test.

AMD Ryzen 7 5800 H will be one of the most powerful Cezanne-H APUs, ready for 2021 year. It has 8 cores and 16 threads. According to GeekBench, the base clock is 3.2 GHz. For comparison, AMD Ryzen 7 4800 H had a base clock of 2.9 GHz, Ryzen 9 4900 HS was clocked at 3 GHz, while the top Ryzen 9 4900 H clocked at 3.3 GHz. According to the same program, the turbo clock speed is expected to reach 4.4 GHz. Ryzen 9 5900 HS (4.5 GHz) and Ryzen 9 5900 HX (4 , 6 GHz + OC possibility). The new APU will also receive twice as much L3 cache – instead of 8 MB we will get 16 MB. One of the vendors currently working on laptops with AMD Cezanne-H is Acer. GeekBench reveals the presence of a new version of Acer Nitro 5.

In the test single-threaded, AMD Ryzen 7 5800 H scored 1475 points, which is on average 20 – 35% better result (it all depends on specific laptops) than the predecessor AMD Ryzen 7 4800 H. Anyway, the increase in single-threaded performance should be visible to the naked eye during specific tests and everyday use. It is no accident that the new Cezanne-H APUs will also be combined with top NVIDIA GeForce RTX cards 3000. In the multithreaded test the result is 7630 points, which is on average 10 – 15% higher result compared to its predecessor. Therefore, another powerful processor from AMD for laptops is being prepared.
