The AMD Radeon RX 7800M, based on the RDNA 3 architecture, is set to power the upcoming ONEXGPU 2 eGPU docking station by ONEXPLAYER. This new graphics card is expected to bring significant performance improvements to the mobile gaming market, positioning itself as a competitive option in the high-end mini laptop and handheld gaming PC GPU segment.
RDNA 3 Architecture: A Deep Dive
RDNA 3, AMD’s latest GPU architecture, introduces significant enhancements over its predecessor, promising better performance for AAA titles. The architecture features a new dual compute unit design with increased floating-point throughput, doubling the FP32 performance per compute unit. Cache sizes have been expanded, with L0 and L1 caches doubling in capacity and L2 cache increasing by 1.5x compared to RDNA 2, making it optimal for AAA gaming.
RDNA 3 also implements a chiplet design, separating the Graphics Compute Die (GCD) and Memory Cache Dies (MCDs), allowing for improved scalability and manufacturing flexibility. The architecture supports higher clock speeds, with the front end operating at 2.5 GHz and shaders at 2.3 GHz, resulting in up to 25% power savings. Additionally, RDNA 3 introduces a dedicated media engine based on VCN 4.0, offering improved encoding capabilities, including support for AV1 encoding.
