RTX 5090 vs RTX 5080

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.

Last updated

NVIDIA GeForce RTX 5090

$1,999 MSRP · 32 GB · 575 W · index 100 at 1440p

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.

NVIDIA GeForce RTX 5080

$999 MSRP · 16 GB · 360 W · index 74 at 1440p

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.

Winner by category

Each category is decided by the same numbers used everywhere else on the site. A category with no clear leader says so rather than picking one.

The shape of the trade-off

All six axes are normalised to a 0-100 scale so they can share one chart. Performance and ray tracing are CompareYourGPU’s estimated indices; value, VRAM, efficiency and features are each card’s standing relative to every other card tracked here.

Normalised comparison of RTX 5090, RTX 5080 across six criteria, judged at 1440p.

Performance, memory and value

Estimated performance index at 1440p. 100 is the fastest card CompareYourGPU tracks.

CompareYourGPU estimate aggregated from public review coverage, not a measurement.

Estimated frame rate at 1440p in a typical modern AAA game at High settings, no upscaling.

Modelled from the performance index. Not a measured benchmark. Real results vary widely by title.

VRAM capacity.

Capacity alone is not the whole story: memory bus width and bandwidth decide how much of it the GPU can actually use.

Launch price.

CompareYourGPU scores value from launch MSRP because it does not carry a verified live price feed. Street prices differ.

Which one should you buy?

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.

Maximum performance

RTX 5090

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.

Best value

RTX 5080

Delivers the most performance per dollar of the cards compared, at $999. Choose this if the difference in price matters more to you than the difference in frame rate.

Ray tracing

RTX 5090

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.

Memory headroom

RTX 5090

Carries 32 GB, the most headroom of the cards compared at 1440p. Memory is usually what dates a card before raw speed does.

Small or quiet builds

RTX 5080

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 overall

RTX 5090

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.

RTX 5090 vs RTX 5080: common questions

Is the RTX 5090 twice as fast as the RTX 5080?
No. It costs twice as much and delivers a substantial but smaller performance advantage. The bigger practical differences are the 32 GB memory pool and the ability to run path-traced games at high resolutions without heavy upscaling.
Can I run an RTX 5090 on my current power supply?
Only if it is a high-quality 1,000 W-class unit with the right connector. At 575 W the RTX 5090 is the most demanding consumer card here by a wide margin. The RTX 5080 at 360 W is far easier to accommodate.
Does 32 GB of VRAM matter for gaming?
Not for games alone. No current title needs anywhere near 32 GB. It matters for creator and AI workloads, and it is insurance for the future rather than a benefit you will see today.
