PowerColor accidentally revealed the initial images of its AMD Radeon RX 7800 XT Red Devil graphics card. These images confirm that the RX 7800 XT is based on an enhanced version of the "Navi 32" GPU, rather than the compact "Navi 31" that powers the limited edition RX 7900 GRE. The "Navi 32" is a chiplet-based GPU, similar to the "Navi 31," but smaller in size. It features a 5 nm GCD (graphics compute die) with 60 RDNA3 compute units, equating to 3,840 stream processors, 120 AI accelerators, 60 Ray accelerators, 192 TMUs, and potentially 128 ROPs. This GCD is accompanied by four 6 nm MCDs (memory cache dies), each containing a 16 MB segment of the GPU's 64 MB Infinity Cache memory, forming its 256-bit GDDR6 memory interface.
The specifications provided by PowerColor confirm that the RX 7800 XT fully utilizes the "Navi 32," enabling all 60 CUs and the chip's complete 256-bit memory interface to support 16 GB of memory. The RX 7800 XT operates at a memory speed of 18 Gbps, resulting in a memory bandwidth of 576 GB/s. The PowerColor RX 7800 XT Red Devil includes a dual-BIOS, and assuming the "standard/silent" BIOS runs the card at AMD reference clock speeds, the Game clocks are expected to be 2210 MHz, with a boost clock of 2565 MHz. The Red Devil is powered by a dual 8-pin PCIe power connector setup (with a maximum power of 375 W), and its cooler is visibly smaller than the one found on the company's RX 7900 series Red Devil cards. The card is equipped with a 16+2 phase VRM. With the release of the card's images, a global product launch is anticipated within the next 30 days.
