AMD has recently submitted two new Ryzen 5000 series CPUs to the USB Implementers Forum for compliance. The first listing for a Ryzen 9 5980HX is a new SKU which we haven't seen before which would be positioned above the 5900HX, 5900H, and 5900HS. It is unclear what this processor will offer whether it be higher clocks, more cores, or something else. These new Zen 3 Cezanne Ryzen 5000H mobile processors are expected to be announced by AMD next week.
The second processor submitted by AMD is the Ryzen 7 5700G which appears to be a desktop Zen 3 Cezanne APU. The processor is likely to feature 8 cores and 16 threads, but clock speeds are GPU specifications are unknown. The current generation Ryzen 4000G series is only available to OEMs and was not released to the DIY market. This new desktop APU will be a significant step up from the quad-core Ryzen 5 3400G which is the fastest APU available from AMD in the DIY market.
