Radeon RX 6900 XT vs Radeon RX 5700: In-Depth Breakdown
Performance: Radeon RX 6900 XT vs Radeon RX 5700
The Radeon RX 6900 XT is dramatically faster, around 167% ahead of the Radeon RX 5700. That gap is enough to move it up a tier: the Radeon RX 6900 XT is comfortable at 1440p, while the Radeon RX 5700 is better matched to 1080p. The Radeon RX 6900 XT packs 5,120 stream processors versus 2,304 on the Radeon RX 5700.
Price & Value
The Radeon RX 5700 currently lists from $578 SGD, $650 SGD less than the Radeon RX 6900 XT at $1,228 SGD. Because it's both faster and competitively priced, the Radeon RX 6900 XT wins on performance-per-dollar by about 25%. The Radeon RX 5700 still sits about $229 SGD above its $349 SGD MSRP. The Radeon RX 6900 XT still sits about $229 SGD above its $999 SGD MSRP.
Power & Efficiency
On power, the Radeon RX 5700 is the gentler choice at 180W versus 300W. The Radeon RX 6900 XT is more efficient per watt because it's faster, but its higher 300W draw means more heat and a bigger PSU. Its more modern RDNA 2 architecture on a TSMC N7 process is part of why it does more with each watt.
VRAM & Future-Proofing
The Radeon RX 6900 XT carries 16GB versus 8GB on the Radeon RX 5700. The extra 8GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The Radeon RX 6900 XT's memory is also faster — 512 GB/s versus 448 GB/s — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: Radeon RX 5700 or Radeon RX 6900 XT?
The Radeon RX 6900 XT 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 5700 if you find it at a steep discount.
