(95).Jan 2nd 2023 AMD Radeon RX 7900 XTX May Feature Faulty Coolers, Causing Overheating (279).Feb 20th 2023 AMD RDNA4 Architecture to Build on Features Relevant to Gaming Performance, Doesn't Want to be Baited into an AI Feature Competition with NVIDIA (211).Oct 31st 2022 AMD Radeon RX 7000 RDNA3 To Launch Early December (58).Nov 15th 2022 AMD Confirms Radeon RX 7900 Series Clocks, Direct Competition with RTX 4080 (166).Dec 11th 2022 First Alleged AMD Radeon RX 7900-series Benchmarks Leaked (146).Nov 3rd 2022 AMD Announces the $999 Radeon RX 7900 XTX and $899 RX 7900 XT, 5nm RDNA3, DisplayPort 2.1, FSR 3.0 FluidMotion (336).Nov 3rd 2022 AMD Radeon RX 7900 XTX Performance Claims Extrapolated, Performs Within Striking Distance of RTX 4090 (164).Sep 22nd 2022 AMD Cuts MSRPs of Radeon RX 6000 Series Graphics Cards (94).The RX 7900 XTX is confirmed to use 20 Gbps GDDR6 memory in this slide, for 960 GB/s of memory bandwidth. The L1 caches by 300%, and the L2 cache shared among the shader engines, by 50%. The L0 caches on the compute units is now increased numerically by 240%. 'Navi 31' hence has a total Infinity Cache size of 96 MB-which may be less in comparison to the 128 MB on 'Navi 21,' but AMD has shored up cache sizes across the GPU. In the scheme of things, the GPU has a contiguous and monolithic 384-bit wide memory bus, because every modern GPU uses multiple on-die memory controllers to achieve a wide memory bus. Six of these add up to the GPU's 384-bit GDDR6 memory interface. Custom interconnects tie it with the six MCDs.Įach MCD has 16 MB of Infinity Cache (元 cache) and a 64-bit GDDR6 memory interface (two 32-bit GDDR6 paths). It features the latest-generation multimedia engine with dual-stream encoders and the new Radiance display engine with DisplayPort 2.1 and HDMI 2.1a support. The GCD interfaces with the system over a PCI-Express 4.0 x16 host interface. The slide details the 'Navi 31' MCM, with its central graphics compute die (GCD) chiplet that's built on the 5 nm EUV silicon fabrication process, surrounded by six memory cache dies (MCDs), each built on the 6 nm process. An alleged leaked company slide details AMD's upcoming 5 nm 'Navi 31' GPU powering the next-generation Radeon RX 7900 XTX and RX 7900 XT graphics cards.
