Twice the price for a large but not proportional performance gain, plus double the memory and a 215 W increase in board power. The question is whether the top of the range is a product or a statement.

The fastest consumer graphics card on the market and the only one that treats 4K at high refresh rates as routine. It also asks for a 575 W power budget, a large case and flagship money, which is why it only makes sense at the very top of a build.
A capable 4K card with the full RTX 50 feature set at roughly half the price of the flagship. The 16 GB memory pool is the one specification that invites debate at this price point.
RTX 5090 comes out ahead of RTX 5080.
The score blends performance at 1440p (50%), performance per dollar (30%) and memory headroom (20%), each against every card CompareYourGPU tracks. Fewer than three points apart counts as level. How verdicts are calculated.

CompareYourGPU estimate aggregated from public review coverage, not a measurement.
Modelled from the performance index. Not a measured benchmark. Real results vary widely by title.
Capacity alone is not the whole story: memory bus width and bandwidth decide how much of it the GPU can actually use.
The short version: the RTX 5090 is faster, but the RTX 5080 offers better value at the prices on record. Which of those matters more is the decision.
Based on the specifications, estimated performance indices and prices on record for these cards. How verdicts are calculated.
Highest estimated performance index at 1440p of the cards compared here, at 100. It is the right answer if frame rate is the only thing you are optimising for.
Delivers the most performance per dollar of the cards compared, at $1,973. Choose this if the difference in price matters more to you than the difference in frame rate.
Strongest ray-traced performance here, with an estimated ray tracing index of 100 at 1440p. It also carries DLSS 4 Super Resolution, which is how ray tracing becomes practical.
Carries 32 GB, the most headroom of the cards compared at 1440p. Memory is usually what dates a card before raw speed does.
Best performance per watt of the cards compared, drawing 360 W. That means less heat, quieter fans and less pressure on your power supply.
Best balance of speed, price and memory of the cards compared: 50% performance at 1440p, 30% performance per dollar, 20% memory headroom. Not necessarily the fastest.
