The Best 12GB GPUs
From the Arc B580 Challenger to the MSI RTX 5070 Ventus 3X: five graphics cards ranked on video memory and cooler thickness, with who should skip each one.
By The PC Journal editorial team
12 min read5 products evaluated
12GB of VRAM covers 1080p and most 1440p games at high settings. Every pick has 12GB, ordered from the lowest price.
Our comparison rests on published figures for GPU, VRAM and memory; nothing here was tested in-house, and where a maker leaves out thickness, we say so.

ASRock Intel Arc B580 Challenger 12GB OC on Amazon (opens in a new tab)
Intel's Arc B580 brings 12GB of GDDR6 to the entry tier, more than the 8GB common at this price.
Best for
- Spending as little as possible.
Skip if
- Look at the other picks if you need a feature not covered above.
Why we like it
ASRock's Challenger version is 249mm long and needs one 8-pin plug and a 650W PSU. No other pick in this guide offers an arc B580 gpu; compare the MSI 4070 Ventus 3X E1, which has an RTX 4070 gpu. It shares GDDR6 memory with the ASUS Prime 9070 GRE and MSI 4070 Ventus 3X E1; the MSI RTX 5070 Ventus 3X goes with GDDR7 memory.
You get a 2740MHz boost clock here, which sets it apart from the MSI RTX 5070 Ventus 3X and its a 2557MHz boost clock. It also comes with a 192-bit memory bus at 19Gbps and dual-fan cooling with 0dB fan stop. Measure for 249mm and 2 slots before ordering the Arc B580 Challenger.
Power for the Arc B580 Challenger comes through 1 x 8-pin, with 650W the maker's minimum PSU. It undercut the ASUS Prime 9070 GRE and every other pick on price at the time of writing.

Strong Alternative3 of 5
Gigabyte GeForce RTX 4070 WINDFORCE OC 12G on Amazon (opens in a new tab)
This Gigabyte Windforce OC RTX 4070 adds a dual BIOS switch and an anti-sag bracket, and it was the least expensive RTX 4070 here at the time of writing.
Best for
- Buyers who want dual BIOS switch.
Skip if
- Skip it if price comes first: the Arc B580 Challenger cost less when we checked.
Why we like it
It supports DLSS 3 frame generation, and third-generation RT cores give up to twice the ray tracing performance. Like the MSI 4070 Ventus 3X E1, it has an RTX 4070 gpu, while the ASUS Prime 9070 GRE uses an RX 9070 GRE gpu. GDDR6X memory is unique to it among these picks, while the ASUS Prime 9070 GRE uses GDDR6 memory.
No dimensions are published for the Gigabyte 4070 Windforce; 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 4070 Windforce with the maker. On price it sat third of 5, between the cheaper ASUS Prime 9070 GRE and the pricier MSI 4070 Ventus 3X E1, at the time of writing. The maker doesn't give its cooler thickness; if that figure matters, the Arc B580 Challenger comes in at 2-slot.

How We Chose
Each pick was assessed across 4 criteria weighted for real-world use.
- Power
- We noted the power connector and recommended power supply where listed.
- Fit
- We recorded length and slot thickness where the maker lists them, plus low-profile and SFF-Ready status.
- GPU and memory
- We compared the chip, video memory capacity and memory type stated in each listing.
- Cooling and extras
- We checked cooler design, fan-stop modes, dual BIOS, support brackets and display outputs.
What to Look for in a 12GB GPUs
Key buying criteria so you get the right fit the first time.
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.
Check length and thickness
Partner cards of the same GPU can differ by several centimetres. Compare the card's length with the case's GPU clearance, allowing for front fans or a radiator, and check how many slots it covers.
Pair it with a balanced CPU
A fast card with an old CPU can stall at high frame rates, especially at 1080p. At 4K the GPU does most of the work, so the CPU matters less.
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.
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.
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
What is the least I can spend on one of these graphics cards?
The Arc B580 Challenger cost the least when we checked, and the MSI RTX 5070 Ventus 3X sat at the top of the range. Prices move often, so check the current listing before buying.
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.
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.
Do I need a GPU support bracket?
Long, heavy cards can sag and stress the slot. Some come with a support stand or bracket; otherwise one is inexpensive to add.
Should I choose AMD or NVIDIA?
Compare price and memory at your budget first, then features such as DLSS or FSR support in your games and hardware encoding if you stream.
Bottom Line
Our first pick is the Arc B580 Challenger, chosen for the lowest price of the group at our last check. Look at the ASUS Prime 9070 GRE for a phase-change GPU thermal pad, the Gigabyte 4070 Windforce for a dual BIOS switch and the MSI 4070 Ventus 3X E1 for a triple-fan Ventus cooler if those matter more to you.
Lower texture quality first if a new game warns about VRAM; it costs less image quality than resolution.
