The AMD Ryzen 7 5800G leaks with PCIe 3.0 support and a Radeon RX Vega 8 GPU
It seems that AMD has a faster alternative to the Ryzen 7 5700G in development, and one that may be the company's premier Ryzen 5000 Desktop APU. According to a GPU-Z validation page, the chip in question is the Ryzen 7 5800G, which is also known as AMD Eng Sample: 100-000000263-30_Y.
GPU-Z does not, unsurprisingly, reveal many details about the Ryzen 7 5800G. However, we would expect it to have eight cores and a boost clock of more than 4.75 GHz. The Ryzen 7 5800G should feature 16 MB of L3 cache, too.
The validation page confirms that the Ryzen 7 5800G will feature an AMD Radeon RX Vega 8 GPU, though. This integrated GPU has eight Compute Units (CUs), 8 ROPs, 8 TMUs and 512 stream processors, along with a bandwidth of 57.6 GB/s on a 128-bit bus width. GPU-Z reports that the GPU has a clock speed of 1,800 MHz and that it supports PCIe 3.0. While the latter will be true of final chips, we would expect the GPU's clock speed to be closer to the 2,100 MHz speed of the GPU found in the Ryzen 7 4750G.
The Ryzen 5000 Desktop APU series will supposedly arrive in Q2 2021, according to Wccftech. The website adds that consumers will be able to purchase the APUs independently, unlike with the Ryzen 4000 Desktop APUs series that AMD consigned to pre-built systems.
