The Best GPUs for the Core Ultra 9 285K
We weighed five graphics cards on video memory and card length, and the PowerColor Hellhound 7900 XTX costs the least.
By Alex Morgan, PC Hardware Editor
12 min read5 products evaluated
A Core Ultra 9 285K build usually targets 4K or heavy creative work. Every pick is an RTX 5080, RTX 4090, RTX 5090 or RX 7900 XTX, ordered by VRAM.
The order reflects GPU, VRAM and memory from maker specifications; we did not test these graphics cards ourselves, and a missing length is flagged, not filled in.

The ASUS TUF 5090 stands out for a dual BIOS switch for Quiet or Performance, and it adds 0dB fan stop at light loads.
Best for
- Buyers who want dual BIOS switch for Quiet or Performance.
Skip if
- If budget leads, the PowerColor Hellhound 7900 XTX was cheaper at our last price check.
Why we like it
It also offers a 32GB video memory and offers a 2.5-slot cooler thickness. It matches the ASUS TUF RTX 5090 on video memory (32GB). Like the ASUS TUF RTX 5090, it has an RTX 5090 gpu, while the PowerColor Hellhound 7900 XTX uses an RX 7900 XTX gpu.
It shares GDDR7 memory with the ASUS TUF RTX 5090; the PowerColor Hellhound 7900 XTX goes with GDDR6 memory. The ASUS TUF 5090 occupies 2.5 slots, but no length is published, so check the maker's spec page against your case. Its power connector and recommended PSU are not published, so confirm both for the ASUS TUF 5090 with the maker.
SFF-Ready is NVIDIA's size guideline, not a guarantee the ASUS TUF 5090 fits every small case. On price it sat fourth of 5, between the cheaper MSI 4090 Gaming Slim and the pricier ASUS TUF RTX 5090, at the time of writing.
