Radeon RX 7900 GRE vs Radeon RX 6650 XT: In-Depth Breakdown
Performance: Radeon RX 7900 GRE vs Radeon RX 6650 XT
The Radeon RX 7900 GRE is dramatically faster, around 126% ahead of the Radeon RX 6650 XT. That gap is enough to move it up a tier: the Radeon RX 7900 GRE is comfortable at 4K with upscaling and native 1440p, while the Radeon RX 6650 XT is better matched to 1080p. The Radeon RX 7900 GRE packs 5,120 stream processors versus 2,048 on the Radeon RX 6650 XT.
Price & Value
Right now the Radeon RX 6650 XT starts at $3,515 AED against $6,479 AED for the Radeon RX 7900 GRE. Because it's both faster and competitively priced, the Radeon RX 7900 GRE wins on performance-per-dollar by about 23%. The Radeon RX 6650 XT still sits about $3,116 AED above its $399 AED MSRP. The Radeon RX 7900 GRE still sits about $5,930 AED above its $549 AED MSRP.
Power & Efficiency
The Radeon RX 6650 XT pulls less power (180W vs 260W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 7900 GRE draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern RDNA 3 architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 16GB against 8GB, the Radeon RX 7900 GRE has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6650 XT's 8GB can fall short. The Radeon RX 7900 GRE's memory is also faster — 576 GB/s versus 280 GB/s (256-bit vs 128-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX 7900 GRE is roughly 2 years newer than the Radeon RX 6650 XT (RDNA 3 vs RDNA 2), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Radeon RX 6650 XT or Radeon RX 7900 GRE?
The Radeon RX 7900 GRE 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 6650 XT if you find it at a steep discount.
