AMD at Computex 2021: 5000G APUs, 6000M Mobile GPUs, FidelityFX Super Resolution, and 3D Chiplets

Accepted submission by takyon at 2021-06-01 03:41:28

AMD's Ryzen 5000G APUs [] now have a release date for the DIY market: August 5th []. The 8-core Ryzen 7 5700G has a suggested price of $359, while the 6-core Ryzen 5 5600G will be $259.

AMD announced the Radeon RX 6800M, 6700M, and 6600M discrete GPUs for laptops [], promising better performance, efficiency, and battery-constrained performance. The Radeon RX 6800M is a 40 compute unit design (equivalent to the Radeon RX 6700 XT on desktop) with 12 GB of VRAM.

AMD biggest announcements were the introduction of FidelityFX Super Resolution [] (FSR) and the demonstration of a 3D chiplet design. FSR uses a spatial scaling algorithm to upscale game graphics for higher frame rates at a given resolution. The algorithm competes with Nvidia's Deep Learning Super Sampling (DLSS), but will be released as open source and work with some older AMD GPUs, integrated graphics, as well as competing products from Nvidia and Intel (it was shown running on an Nvidia GTX 1060).

AMD CEO Lisa Su also showed off [] a modified, delidded Ryzen 9 5900X CPU prototype, with "3D V-Cache technology". It was identical to the retail 5900X with the exception of through-silicon via [] (TSV) stacked L3 cache, with 3 layers. This allowed the 5900X prototype to have 192 MB of total L3 cache instead of 64 MB (96 MB per 8-core chiplet). AMD claims it can run games with an average of +15% performance (simply due to the larger cache size), and some version of this will appear in products that are starting production at the end of 2021.
