Radeon RX 7900 XTX vs Arc A770: In-Depth Breakdown
Performance: Radeon RX 7900 XTX vs Arc A770
The Radeon RX 7900 XTX is dramatically faster, around 121% ahead of the Arc A770. That gap is enough to move it up a tier: the Radeon RX 7900 XTX is comfortable at 4K and high-refresh 1440p, while the Arc A770 is better matched to 1440p.
Power & Efficiency
On power, the Arc A770 is the gentler choice at 225W versus 355W. The Radeon RX 7900 XTX is more efficient per watt because it's faster, but its higher 355W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The Radeon RX 7900 XTX carries 24GB versus 16GB on the Arc A770. The extra 8GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Features & Ecosystem
Beyond raw numbers, the Radeon RX 7900 XTX brings AMD FSR upscaling and strong rasterization value, while the Arc A770 offers Intel XeSS upscaling and AV1 encoding. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: Radeon RX 7900 XTX or Arc A770?
The Radeon RX 7900 XTX is the faster card by about 121%. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
