An upgrade has to fit a PC you already own. Before choosing, check your power supply's wattage and PCIe connectors, the gap in front of the card in your case, and whether your board has a PCIe x16 slot.

We compared connectors, recommended PSU and size from each listing and the chipmakers' guidance; we did not install these cards in test systems.

Biggest Upgrade1 of 5

GIGABYTE Radeon RX 9070 XT Gaming OC 16G

Gigabyte's RX 9070 XT Gaming OC pairs AMD's top RDNA 4 chip with 16GB of GDDR6 and a WINDFORCE cooler.

Best for

PCs with a 750W or larger supply.

Skip if

Its cooler thickness is not published, which rules it out if you need that number.
GIGABYTE Radeon RX 9070 XT Gaming OC 16G

Why we like it

At the time of writing it cost about half as much as the RTX 5080 cards we researched, which makes it the strongest value in the upper tiers. It matches the ASUS Dual 9060 XT 16GB on video memory (16GB). No other pick in this guide offers an RX 9070 XT gpu; compare the MSI 4070 Ventus 3X E1, which has an RTX 4070 gpu.

It also offers server-grade thermal conductive gel and RGB lighting. No dimensions are published for the Gigabyte RX 9070 XT Gaming OC; get length and thickness from the maker's page first. Its power connector and recommended PSU are not published, so confirm both for the Gigabyte RX 9070 XT Gaming OC with the maker. On price it sat fourth of 5, between the cheaper MSI 4070 Ventus 3X E1 and the pricier ASUS Prime RTX 5070, at the time of writing.

What to Look for in a GPU Upgrade

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

  1. How much video memory you need

    Across these 5 picks video memory spans 8GB (the ASRock RX 7600 Challenger Pro) to 16GB (the Gigabyte RX 9070 XT Gaming OC). The ASUS Dual 9060 XT 16GB comes second at 16GB, in the same price tier as the Gigabyte RX 9070 XT Gaming OC.

  2. Memory

    The Gigabyte RX 9070 XT Gaming OC, the ASUS Dual 9060 XT 16GB, the MSI 4070 Ventus 3X E1 and the ASRock RX 7600 Challenger Pro list GDDR6; the ASUS Prime RTX 5070 lists GDDR7.

  3. Boost clock

    The ASUS Prime RTX 5070 lists 2587MHz (OC mode); the ASUS Dual 9060 XT 16GB lists 3250MHz (OC mode); the MSI 4070 Ventus 3X E1 lists 2520MHz; the ASRock RX 7600 Challenger Pro lists 2695MHz. Sort out boost clock before price: it splits 4 stated picks into groups of 1, 1, 1 and 1.

  4. Setup checks

    No dimensions are published for the Gigabyte RX 9070 XT Gaming OC; get length and thickness from the maker's page first. The ASUS Prime RTX 5070 occupies 2.5 slots, but no length is published, so check the maker's spec page against your case. Measure for 303mm and 2.5 slots before ordering the ASRock RX 7600 Challenger Pro.

  5. Extras that separate them

    The ASUS Dual 9060 XT 16GB: 0dB fan stop at light load. The MSI 4070 Ventus 3X E1: GDDR6 memory rather than the GDDR6X on other 4070 cards. The ASRock RX 7600 Challenger Pro: 32MB of Infinity Cache.
