Is the Radeon RX 7900 XTX right for you?
If you find this card at a clear discount and want strong 4K rasterisation with 24GB VRAM and a handy USB-C output, and heavy ray tracing isn't a priority, it's excellent value this generation.
If you want strong ray tracing in heavy path-traced titles or the latest FSR 4 upscaling, the 7900 XTX trails. A current RDNA 4 card or an RTX equivalent makes more sense for those priorities.
Before you buy
Yes at a clear discount for raster-focused 4K gaming. The 24GB VRAM and strong rasterisation hold up well. The main caveat is weaker ray tracing than Nvidia and no FSR 4 support.
It adds display versatility, handy for VR headsets, USB-C monitors, or single-cable display setups. A useful extra alongside the standard HDMI and DisplayPort outputs.
No. The 7900 XTX is RDNA 3, which supports FSR 3 but not the newer RDNA 4-exclusive FSR 4. FSR 3 is good but trails current FSR 4 and DLSS 4 image quality in supported titles.
Sapphire recommends 800W for the 7900 XTX. With a power-hungry CPU, a quality 850W unit gives more headroom against the 355W TDP and transient spikes.
