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 thickness is flagged, not filled in.

Our Picks

ASUS TUF Gaming GeForce RTX 5090

Largest Video Memory1 of 5

ASUS TUF Gaming GeForce RTX 5090 on Amazon (opens in a new tab)

The ASUS TUF RTX 5090 is in a class of its own with 32GB of GDDR7 and 21,760 CUDA cores.

Best for

Buyers who put video memory first.

Skip if

Skip it if price comes first: the ASRock 7900 XTX Phantom Gaming cost less when we checked.

Why we like it

At the time of writing it cost several times more than the other cards here, so it only makes sense when nothing slower will do. On video memory it leads this guide at 32GB, ahead of the ASRock 7900 XTX Phantom Gaming (24GB). No other pick in this guide offers an RTX 5090 gpu; compare the MSI 4090 Gaming X Trio, which has an RTX 4090 gpu.

It shares GDDR7 memory with the Zotac RTX 5080 Solid Core; the ASRock 7900 XTX Phantom Gaming goes with GDDR6 memory. It also offers a 512-bit memory bus at 28Gbps and a GPU holder in the box. It was the highest-priced of the 5 picks at the time of writing, so the case for it rests on what it adds over the MSI 4090 Gaming X Trio and the rest. The maker doesn't give its cooler thickness; if that figure matters, the Zotac RTX 5080 Solid Core comes in at 2.5-slot.

How We Chose

Each pick was assessed across 4 criteria weighted for real-world use.

Cooling and extras
We checked cooler design, fan-stop modes, dual BIOS, support brackets and display outputs.
GPU and memory
We compared the chip, video memory capacity and memory type stated in each listing.
Price tier
We grouped picks by price at the time of writing rather than by listed clock speed.
Fit
We recorded length and slot thickness where the maker lists them, plus low-profile and SFF-Ready status.

What to Look for in a GPUs for the Core Ultra 9 285K

Key buying criteria so you get the right fit the first time.

  1. Treat 8GB of VRAM as the floor

    Some recent games already push past 8GB at high texture settings. Cards with 12GB or 16GB give more room, especially at 1440p and above.

    Two versions of the same chip can differ only in memory; check the capacity in the exact model name.

  2. Plan the power connector and PSU

    Cards use one or two 8-pin PCIe plugs or a single 16-pin 12V-2x6 plug. Confirm your power supply has the right cables and meets the maker's recommended wattage.

  3. Compare upscaling and encoders

    NVIDIA cards support DLSS, AMD cards FSR and Intel cards XeSS. Each game supports a different mix, so check the titles you play.

    Streamers should also compare hardware video encoders.

  4. Count the display outputs

    Most cards offer three DisplayPort outputs and one HDMI, but some swap that balance. Check that the ports match your monitors, TV or VR headset.

  5. Match the card to your monitor

    Resolution and refresh rate decide how much GPU you need. A 1080p screen at 144Hz asks far less than 1440p at 165Hz or 4K.

    Buy for the monitor you use now or will buy soon, not for a resolution you may never run.

  6. Cooler size affects noise

    Larger triple-fan coolers usually run quieter under load than compact dual-fan designs. A 0dB mode stops the fans at light load.

Frequently Asked Questions

Which of these graphics cards has the largest video memory?

The ASUS TUF RTX 5090, at 32GB. The ASRock 7900 XTX Phantom Gaming follows at 24GB, while the Zotac RTX 5080 Solid Core has 16GB.

What is the least I can spend on one of these graphics cards?

At our last price check the ASRock 7900 XTX Phantom Gaming was the cheapest pick and the ASUS TUF RTX 5090 the most expensive; the Sapphire Nitro+ 7900 XTX was the next step up from the ASRock 7900 XTX Phantom Gaming.

Is an 8GB graphics card still enough?

For 1080p with tuned texture settings, often yes. For 1440p or high textures in new games, 12GB or 16GB is safer.

Will a PCIe 5.0 card work in a PCIe 4.0 or 3.0 slot?

Yes, the interface is backward compatible. Cards with a narrow x8 link can lose some performance on PCIe 3.0 boards.

How big a power supply do I need?

Use the maker's recommendation for your exact card, then add headroom if you run a high-power CPU. Also check the connectors, not just the wattage.

Bottom Line

Our first pick is the ASUS TUF RTX 5090, chosen for the largest video memory here (32GB). Look at the ASRock 7900 XTX Phantom Gaming for a lower price than the Sapphire Nitro+ 7900 XTX and the rest when we checked, the Sapphire Nitro+ 7900 XTX for a Vapor-X vapor chamber cooler and the MSI 4090 Gaming X Trio for a TRI FROZR 3 cooler with a copper baseplate if those matter more to you.

Use an ATX 3.1 power supply with a native 12V-2x6 cable for NVIDIA's high-end cards.
