RDNA 3 is bringing performance per watt and performance per dollar.
The GPU is where things get interesting. AMD is stuffing 58 billion transistors into its new GPUs, though they're not all in one place. These are chiplet-based gaming GPUs—the world's first, as AMD is keen to add.
The actual rendering cores responsible for chomping through floating point and integer operations are located on what's called the GCN. Both RX 7900 XTX and RX 7900 XT come with a single GCN each, at 300mm2. The GCN is built on TSMC's 5nm process node, and includes not only the hardware required for AI, rendering, and ray tracing, but also the media and display engines.
Surrounding this GCN, on both cards, will be six MCDs. These are much smaller chips than the GCN, each one sized at 37mm2. These are built on TSMC's 6nm process node. Each of these contains a 64-bit memory controller and second-generation Infinity Cache. That should mean we can expect a full 96MB of Infinity Cache on the 7900 XTX, whereas the 7900 XT should come with 80MB. AMD didn't specify this spec for either card during its event, so I'm having to infer that from other comments on the MCN design.RDNA 3 uses split clocks across the shader and front-end. According to the company's engineers, gaming performance was limited by front-end more than the actual shaders themselves.

Watch AMD announce its new Radeon RX 7000-series graphics cards right hereAlan has been writing about PC tech since before 3D graphics cards existed, and still vividly recalls having to fight with MS-DOS just to get games to load. He fondly remembers the killer combo of a Matrox Millenium and 3dfx Voodoo, and seeing Lara Croft in 3D for the first time. He's very glad hardware has advanced as much as it has though, and is particularly happy when putting the latest M.2 NVMe SSDs, AMD processors, and laptops through their paces. He has a long-lasting Magic: The Gathering obsession but limits this to MTG Arena these days.
