AMD Ryzen 7 5800U ZEN 3 ‘Cezanne’ CPU With Powerful Vega GPU Leaks Online

The AMD Ryzen 5000 series of CPUs have been appearing online for quite some time. While the CPUs appear to have the latest ZEN 3 Core Architecture, AMD has some AMD Ryzen 5000 Series processors with ZEN 2 Cores as well. Now a new CPU has appeared online which appears to belong to the latest ZEN 3-based lineup.

The AMD Ryzen 5000 Series of processors are split into two generations despite having the latest branding. The processors codenamed ‘Lucienne’ will be part of the AMD Ryzen 5000 Series but will have ZEN 2 Cores, and are considered as a Renoir refresh. Meanwhile, AMD will also sell the true ZEN 3 Core-based Ryzen 5000 Series of CPUs that are codenamed ‘Cezanne’. The new CPU that has leaked online, appears to belong to this new ZEN 3 family.

AMD Ryzen 5 5800U Cezanne CPU Leaks Online:

AMD has quietly split the Ryzen 5000U mobile computing processor series into Lucienne and Cezanne. Some SKUs that leaked earlier, such as Ryzen 5 5500U or Ryzen 7 5700U, were both ZEN 2-based or in other words, a Renoir refresh. Meanwhile, the new AMD CPU that has just been spotted on Geekbench via Leakbench is the first mobile ZEN 3 CPU. The listing identifies the AMD CPU as AMD Ryzen 7 5800U.

According to the listing, the AMD Ryzen 7 5800U has a Base Clock of 1.9 GHz and a Boost Clock of 4.4 GHz. Previous reports suggested a Base Clock of 2.0 GHz. Hence, it is unclear if the new CPU is being tested and optimized. Nonetheless, the new CPU has a 200 MHz higher Boost Block compared to the Ryzen 7 4800U, which is the true “Renoir” CPU. Incidentally, a recent Tweet has reaffirmed the 2.0 GHz Base Clock.

I do love me some teasers. Let's talk business now. Cezanne and Lucienne 😋

Speaking of the integrated AMD Radeon Vega Graphics, the AMD Ryzen 7 5800U appears to be a very capable processor that could support high resolution gaming. According to previous reports, the Vega GPU cores are also going to see a boost to 2.0 GHz, from 1.75 GHz on the previous Renoir generation.

Based on the Geekbench listing, the Ryzen 7 5800U appears to be 20 percent faster than Ryzen 7 5700U in the single-threaded benchmark. However, the new CPU appears to falter in the multi-threading performance. According to the listing, it offers only a 2.6 percent improvement in the multi-threaded benchmark. This suggests AMD is still tweaking its latest ZEN 3 mobile computing CPUs.
