Performance: Arc A750 vs Radeon RX 6400
The Arc A750 is dramatically faster, around 200% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the Arc A750 is comfortable at 1080p, while the Radeon RX 6400 is better matched to entry-level 1080p.
Price & Value
Right now the Radeon RX 6400 starts at $852 AED against $935 AED for the Arc A750. Because it's both faster and competitively priced, the Arc A750 wins on performance-per-dollar by about 173%. The Radeon RX 6400 still sits about $693 AED above its $159 AED MSRP. The Arc A750 still sits about $646 AED above its $289 AED MSRP.
Power & Efficiency
The Radeon RX 6400 draws just 53W versus 225W for the Arc A750, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom.
VRAM & Future-Proofing
With 8GB against 4GB, the Arc A750 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6400's 4GB can fall short.
Features & Ecosystem
Beyond raw numbers, the Arc A750 brings Intel XeSS upscaling and AV1 encoding, while the Radeon RX 6400 offers AMD FSR upscaling and strong rasterization value. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: Arc A750 or Radeon RX 6400?
The Arc A750 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Radeon RX 6400 if you find it at a steep discount.
