Radeon RX 6800 vs Arc A750: In-Depth Breakdown
Performance: Radeon RX 6800 vs Arc A750
The Radeon RX 6800 is dramatically faster, around 72% ahead of the Arc A750. That gap is enough to move it up a tier: the Radeon RX 6800 is comfortable at 1440p, while the Arc A750 is better matched to 1080p.
Price & Value
Right now the Arc A750 starts at $242 CAD against $500 CAD for the Radeon RX 6800. Despite being slower, the Arc A750 offers the better performance-per-dollar (~20% better value), so budget-focused buyers should weigh it carefully. The Arc A750 is trading below its $289 CAD MSRP — a genuine deal. The Radeon RX 6800 is trading below its $579 CAD MSRP — a genuine deal.
Power & Efficiency
The Arc A750 is the lighter draw at 225W against the Radeon RX 6800's 250W, making it the easier card to power and cool. The Radeon RX 6800 draws more in absolute terms but squeezes out more performance per watt, so budget for a beefier PSU if you go that route.
VRAM & Future-Proofing
The Radeon RX 6800's 16GB (vs 8GB on the Arc A750) gives it more room for 4K textures and memory-hungry creative or AI workloads.
Generation & Longevity
The Arc A750 is roughly 2 years newer than the Radeon RX 6800 (Alchemist vs RDNA 2), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Arc A750 brings Intel XeSS upscaling and AV1 encoding, while the Radeon RX 6800 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 6800?
Choose the Radeon RX 6800 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Arc A750 stretches your money further for only slightly lower performance.
