RTX 4050 Laptop vs RX 6400: the short version

Two strong options in the same gpu class, aimed at different buyers. Below is a clean side-by-side, the real performance gap, and a no-nonsense recommendation so you stop second-guessing and buy the one that fits your build and budget.

Side-by-side specs

| Spec | RTX 4050 Laptop | RX 6400 | | --- | --- | --- | | Vendor | NVIDIA | AMD | | Tier | entry | entry | | Released | 2023 | 2022 | | VRAM | 6 GB GDDR6 | 4 GB GDDR6 | | Board power | 115 W | 53 W |

Real-world performance (estimated)

Estimated average FPS from a tuned config — your CPU, resolution and settings shift these, but the gap between the two holds:

| Model | 1080P Low | 1080P Med | 1080P High | 2K Med | 4K Med | | --- | --- | --- | --- | --- | --- | | RTX 4050 Laptop | ~78 | ~63 | ~49 | ~35 | ~17 | | RX 6400 | ~65 | ~52 | ~40 | ~29 | ~14 |

Head-to-head: who wins what

• Performance: RTX 4050 Laptop and RX 6400 trade blows by workload. RTX 4050 Laptop has the edge where its stronger 6 GB GDDR6 and 115 W of headroom matters; RX 6400 wins the rest.
• Efficiency: RX 6400 draws less power and is easier to cool and power.
• Value: Same-class rivals shift price constantly — check current street pricing and let the cheaper one at your target resolution decide value.
• Our pick: Buy RTX 4050 Laptop if you want the outright ceiling and can cool/power it. Buy RX 6400 if you want lower power, lower cost, or a feature the other lacks. (Plan for ~115 W board power plus the rest of the system.)
