The Best Graphics Cards for 4K Gaming
Five graphics cards for 4K gaming, from the RX 9070 XT to the RTX 5090, compared on VRAM, card size, power plugs and PSU needs.

12 min read5 products evaluated

4K gaming asks the most of a graphics card, and the cards that handle it are long, thick and power-hungry. Before comparing speed, check your case clearance, your PSU wattage and whether it has a 16-pin 12V-2x6 cable.
This is a research-led comparison drawn from maker specifications and listings; we did not measure performance ourselves. Independent reviews give the best view of 4K frame rates.

Our Picks
Best for 4K1 of 5
ASUS TUF Gaming GeForce RTX 5080 16GB OC
The ASUS TUF RTX 5080 offers every figure a builder needs: 348mm long, 3.6 slots, a 16-pin 12V-2x6 plug and an 850W PSU.
Best for
- 4K gaming with ray tracing.
Skip if
- Look at the others if this bothers you: a 348mm length needs a roomy case.
Why we like it
Its large cooler and protective PCB coating suit a long-term 4K build. On video memory it ties with the MSI RTX 5080 Ventus 3X, the ASUS Prime and the ASRock RX 9070 XT Steel Legend at 16GB. On card length it trails the group at 348mm, while the ASRock RX 9070 XT Steel Legend comes in at 298mm.
Its 3.6-slot cooler thickness is the thickest in this group; the ASUS Prime leads at 2.5-slot. On recommended power supply it trails the group at 850W, while the ASUS Prime offers 750W. Like the ASUS Prime, it has a 16-pin 12V-2x6 power connector, while the ASRock RX 9070 XT Steel Legend uses a 2 x 8-pin power connector. When we checked, only the MSI RTX 5080 Ventus 3X and cheaper picks cost less, and the ASUS TUF RTX 5090 cost more.

The catch
Card length is its weakest area, and the ASRock RX 9070 XT Steel Legend covers it better at 298mm.
Best Value RTX 50802 of 5
MSI Gaming RTX 5080 16G Ventus 3X OC Black
MSI's Ventus 3X Black puts the same RTX 5080 chip and 16GB of GDDR7 in a plainer card.
Best for
- 4K on NVIDIA without premium cooler pricing.
Skip if
- Its card length is not published, which rules it out if you need that number.
Why we like it
It cost less than the ASUS TUF at the time of writing, but MSI does not list its length in this listing. It matches the ASUS TUF RTX 5080, the ASUS Prime and the ASRock RX 9070 XT Steel Legend on video memory (16GB). You get a 2640MHz boost clock here, which sets it apart from the ASUS Prime and its a 2527MHz (OC mode) boost clock.
It also comes with a 256-bit memory interface and a 7680 x 4320 maximum digital resolution. No dimensions are published for the MSI RTX 5080 Ventus 3X; get length and thickness from the maker's page first. Its power connector and recommended PSU are not published, so confirm both for the MSI RTX 5080 Ventus 3X with the maker. On price it sat third of 5, between the cheaper ASUS Prime and the pricier ASUS TUF RTX 5080, at the time of writing.

Best Entry 4K NVIDIA3 of 5
ASUS Prime GeForce RTX 5070 Ti OC
The ASUS Prime RTX 5070 Ti is the smallest documented 4K option here at 306mm and 2.5 slots.
Best for
- 4K with DLSS in a mid-size case.
Skip if
- Skip it if this is a deal-breaker for you: needs a 16-pin 12V-2x6 power cable.
Why we like it
With DLSS, its 16GB of GDDR7 handles 4K in many games at tuned settings. On video memory it ties with the ASUS TUF RTX 5080, the MSI RTX 5080 Ventus 3X and the ASRock RX 9070 XT Steel Legend at 16GB. On card length it sits mid-pack at 306mm: the ASRock RX 9070 XT Steel Legend comes in at 298mm, and the ASUS TUF RTX 5080 comes in at 348mm.
Its 2.5-slot cooler thickness is the slimmest here; the ASRock RX 9070 XT Steel Legend comes next at 2.9-slot. Nothing else here matches its 750W recommended power supply; the ASRock RX 9070 XT Steel Legend comes closest at 800W. You get an RTX 5070 Ti gpu here, which sets it apart from the ASUS TUF RTX 5090 and its an RTX 5090 gpu.

Best AMD for 4K4 of 5
ASRock Radeon RX 9070 XT Steel Legend 16GB
ASRock's RX 9070 XT Steel Legend is the AMD route to 4K, with 16GB of GDDR6 and a reinforced metal frame.
Best for
- 4K on a lower budget with standard PCIe cables.
Skip if
- Pass on it if calls for a 800W or larger PSU rules it out for your setup.
Why we like it
It uses two 8-pin plugs, which suits power supplies without a 16-pin cable, but the maker recommends 800W. The card measures 298 x 131 x 58mm, and its 16GB of GDDR6 runs at 20Gbps on a 256-bit bus. Outputs are DisplayPort 2.1a and HDMI 2.1b, and the game clock is 2400MHz.
It matches the ASUS TUF RTX 5080, the MSI RTX 5080 Ventus 3X and the ASUS Prime on video memory (16GB). On card length it leads this guide at 298mm, ahead of the ASUS Prime (306mm). On cooler thickness it sits mid-pack at 2.9-slot: the ASUS Prime comes in at 2.5-slot, and the ASUS TUF RTX 5080 comes in at 3.6-slot.
You get GDDR6 memory here, which sets it apart from the ASUS TUF RTX 5090 and its GDDR7 memory. It was the cheapest of the group when we checked; the ASUS Prime was the next step up.

- Video memory trails the ASUS TUF RTX 5090 (32GB)
The catch
If video memory is your priority, the ASUS TUF RTX 5090 (32GB) is the stronger choice.
Most VRAM5 of 5
ASUS TUF Gaming GeForce RTX 5090
The ASUS TUF RTX 5090 is in a class of its own with 32GB of GDDR7 and 21,760 CUDA cores.
Best for
- 4K at maximum settings and local AI work.
Skip if
- The maker gives no card length, so skip it if that figure decides your choice.
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. Nothing else here matches its 32GB video memory; the ASUS TUF RTX 5080 comes closest at 16GB. It also comes with a 512-bit memory bus at 28Gbps and a GPU holder in the box.
No dimensions are published for the ASUS TUF RTX 5090; get length and thickness from the maker's page first. Its power connector and recommended PSU are not published, so confirm both for the ASUS TUF RTX 5090 with the maker. It was the most expensive pick when we checked, so weigh what it adds over the ASUS TUF RTX 5080.

How We Chose
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.

- What we compared
- We set side by side five cards on GPU, video memory, memory and card length from manufacturer specifications. Nothing was tested in-house; 3 of the 9 fields compared are stated for every pick, while card length and cooler thickness have gaps.
- What every pick has in common
- All 5, from the ASUS TUF RTX 5080 to the ASUS TUF RTX 5090, state GPU, video memory and memory.
- Where the specs have gaps
- The MSI RTX 5080 Ventus 3X and the ASUS TUF RTX 5090 give no card length; the MSI RTX 5080 Ventus 3X and the ASUS TUF RTX 5090 give no cooler thickness.
- Price range
- At our last check the picks ran from the ASRock RX 9070 XT Steel Legend ($500 to $1000) to the ASUS TUF RTX 5090 (over $1500).
What to Look for in a GPUs for 4K
Key buying criteria so you get the right fit the first time.
Video memory
Here video memory runs from 16GB on the ASRock RX 9070 XT Steel Legend to 32GB on the ASUS TUF RTX 5090, a 100% spread. The ASUS TUF RTX 5090 is the pick for video memory.
Card length across these picks
Across these 3 picks card length spans 348mm (the ASUS TUF RTX 5080) to 298mm (the ASRock RX 9070 XT Steel Legend). Start with the ASRock RX 9070 XT Steel Legend if card length decides it. The MSI RTX 5080 Ventus 3X and the ASUS TUF RTX 5090 give no card length figure, so 3 of 5 picks are compared here.
