AMD's next big CPU introduction for the desktop segment will be the Zen 2-based Ryzen 4000 'Renoir' APU line. What makes these CPUs really interesting now is the fact that they should provide a good balance of graphics and processor cores in the same housing, enabling low-cost PC builds that are able to play in different applications and work fast at the same time. The latest leaks have already hinted that AMD could deliver a major update with its next APU line.
The latest AMD Ryzen 4000 'Renoir' APU is listed in the User Benchmark database and has been discovered by TUM_APISAK (see below).

According to the leaked data, the Ryzen 4000 CPU has 8 cores and 16 threads clocked at a base frequency of 3.0 GHz and a boost frequency of 4.0 GHz. The core clocks are probably due to the early nature of this chip, as the RETAIL CPUs are likely to be delivered at much faster intervals later on.
The technical pattern is codenamed "100-00000000149-40_40/30_Y", which according to Komachi is the identifier for RN-A1 SKUs or Renoir for the AM4 platform. The CPU was tested on an ASRock B550 Taichi motherboard, which was announced yesterday. AMD's Renoir processor line is expected to be compatible with both B450/X470 and B550/X570 motherboards. The leaker Rogame also reports that there are at least two Renoir chips that are currently being tested. One of them is a 3.5 GHz CPU with a 1750 MHz clocked graphics processor and a 3 GHz variant, in which the graphics processor is also clocked at 1750 MHz.
Two chips are being tested
> 3.5GHz CPU, 1750MHz iGPU
> 3GHz CPU, 1750MHz iGPU (likely the 8C Eng Sample: 100-000000149-40_40/30_Y from Userbenchmark)
I believe both are 8C

Both variants will probably have 8 cores and 16 threads, which would be one of the biggest improvements compared to the Ryzen 3000G APUs with 4 cores and 8 threads. Having fast Zen 2 cores is one thing, but doubling it from the Zen+ cores of the previous generation takes them to a whole new level. AMD's Renoir chips are also completely monolithic and, as seen on mobile platforms, also offer slightly better performance efficiency compared to desktop-based Zen 2 chips. The specific number of CUs that Renoir's desktop chips will have is not known, but the most likely is the use of 8 CUs, just like the Ryzen 9 4900HS, which is equivalent to 512 stream processors.
AMD could even expand that, as the 65W APUs offer more scope for their support, but that seems unlikely at this stage. Memory support would probably remain at 3200 MHz (native), but you can be sure that higher storage files will achieve much better performance results. However, as always, this would be left to the respective buyer and his instinct to experiment.
In terms of performance, the AMD Ryzen 4000 'Renoir' 8 Core ES CPU scores 130 points at 1-core, 264 points at 2-core, 524 points at 4-core, 1051 points at 8-core and 1087 points at 64 core benchmarks. However, the platform on which the chip was tested had only a single 8GB DDR4 module, which was also clocked at a measly 2133 MHz. In the end, this gives little indication of the actual performance.
