The GeForce RTX 5080 is noticeably faster, around 15% ahead of the GeForce RTX 4080 SUPER. That gap is enough to move it up a tier: the GeForce RTX 5080 is comfortable at 4K and high-refresh 1440p, while the GeForce RTX 4080 SUPER is better matched to 4K with upscaling and native 1440p. The GeForce RTX 5080 packs 10,752 CUDA cores versus 10,240 on the GeForce RTX 4080 SUPER.
Price & Value
Right now the GeForce RTX 5080 starts at $1,000 GBP against $2,000 GBP for the GeForce RTX 4080 SUPER. Because it's both faster and competitively priced, the GeForce RTX 5080 wins on performance-per-dollar by about 131%. The GeForce RTX 4080 SUPER still sits about $1,001 GBP above its $999 GBP MSRP.
Power & Efficiency
The GeForce RTX 4080 SUPER pulls less power (320W vs 360W), so it's the easier card to cool and the lighter load on your PSU. The faster GeForce RTX 5080 draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern Blackwell architecture on a TSMC 4N process is part of why it does more with each watt.
Memory & Bandwidth
The GeForce RTX 5080's memory is faster — 960 GB/s versus 736 GB/s — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce RTX 4080 SUPER or GeForce RTX 5080?
The GeForce RTX 5080 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the GeForce RTX 4080 SUPER if you find it at a steep discount.
