AMD Radeon RX 6400
Specifications, where the Radeon RX 6400 sits for gaming, the processor worth pairing with it, and the frame rate the pair returns at every resolution.
Ryzen 5 4500
The Radeon RX 6400 and the Ryzen 5 4500 return about 10 fps on High at 1440p with neither part wasting the other. A processor slower than the Ryzen 5 4500 leaves the Radeon RX 6400 idling, and a faster one adds no frames to a Radeon RX 6400 at this resolution.

What these numbers mean for the Radeon RX 6400
On our index the Radeon RX 6400 scores 12.0, which places it 87th of the 89 graphics cards we track and puts it faster than roughly 2% of them.
The Radeon RX 6400 and the Arc A380 land on exactly the same index score of 12.0, so on raw throughput the two are interchangeable and the choice between them comes down to memory, power draw and price on the day.
With 4 GB of memory the Radeon RX 6400 is limited to 1080p and to older or lighter titles. Modern games exceed a 4 GB budget at almost any preset, and running out produces frame time spikes rather than a gently lower average, so the card feels worse than its 12.0 index suggests.
At 53 W the Radeon RX 6400 is one of the easier cards to power and cool. A modest supply and a standard case will do, and 53 W is low enough to drop into a small build or a prebuilt whose supply you are not replacing.
Released in 2022, the Radeon RX 6400 is a card most people now meet on the used market or in an existing build rather than on a shelf, and after 4 years the only price worth judging a Radeon RX 6400 on is what it costs today.
Radeon RX 6400 frame rate at each resolution
The Radeon RX 6400 paired with the Ryzen 5 4500 on the High preset with 16 GB of system memory. The card is the limit throughout, so the Radeon RX 6400 falls the full 60% from 15 fps to 6 fps as the pixel count rises.
| Resolution | Estimated fps | Limited by |
|---|---|---|
| 1080p (1920 x 1080) | 15 fps | GPU |
| 1440p (2560 x 1440) | 10 fps | GPU |
| 4K (3840 x 2160) | 6 fps | GPU |
How the Radeon RX 6400 compares
6 cards sit within 30% of the Radeon RX 6400 on our gaming index, running from the GeForce GTX 1650 at +25% to the GeForce GTX 1050 Ti at -17%, a window narrow enough that price, memory and power decide it rather than raw speed.
What to pair with the Radeon RX 6400, and when to upgrade
Best CPU for the Radeon RX 6400
When the Radeon RX 6400 becomes the limit, the GeForce RTX 3050 8GB is the next step worth paying for: 22.0 on our index against 12.0, a jump of 83%, which is roughly where an upgrade stops being something you have to look at a counter to notice. See its specs.
