AMD announced a couple of memory-related technologies related to this GPU series launch, with Infinity Cache and Smart Access Memory detailed during the event.
AMD Infinity Cache – A high-performance, last-level data cache suitable for 4K and 1440p gaming with the highest level of detail enabled. 128 MB of on-die cache dramatically reduces latency and power consumption, delivering higher overall gaming performance than traditional architectural designs.
AMD Smart Access Memory – An exclusive feature of systems with AMD Ryzen 5000 Series processors, AMD B550 and X570 motherboards and Radeon RX 6000 Series graphics cards. It gives AMD Ryzen processors greater access to the high-speed GDDR6 graphics memory, accelerating CPU processing and providing up to a 13-percent performance increase on a AMD Radeon RX 6800 XT graphics card in Forza Horizon 4 at 4K when combined with the new Rage Mode one-click overclocking setting.
AMD showcased performance from these new GPUs during the presentation, with the following chart showing gains of up to 2.2X the Radeon RX 5700 XT at 4K resolution – and high resolution gaming appears to be the focus with these cards, which all offer 16GB of VRAM:
