AMD has announced "Cezanne" desktop APUs [wccftech.com] with Zen 3 cores and Vega integrated graphics:
AMD has officially launched [amd.com] its next-generation Ryzen 5000G APUs codenamed Cezanne which features the brand new Zen 3 core architecture. The AMD Ryzen 5000G APUs are aimed at the consumer segment with an initial supply coming to OEM PCs first and later heading out to the gaming & mainstream DIY segment.
The AMD Ryzen 7 5700G will be the flagship offering within the lineup. It will feature 8 cores and 16 threads. The clock speeds are reported at a 3.8 GHz base and a 4.6 GHz boost. The CPU will carry a total of 16 MB L3 and 4 MB L2 cache with the TDP being set at 65W. The APU will also carry a Vega integrated GPU with 8 CUs or 512 stream processors running at clock speeds around 2.0 GHz. The 35W Ryzen 7 5700GE will feature the same specs but reduced core clocks of 3.2 GHz base and 4.6 GHz boost. The CPU should retail at around $350-$400 US.
