RTX 4090 vs RTX 5090

Two generations of the fastest consumer card. The RTX 5090 is the clear winner on every measure, but it launched $400 higher and draws 125 W more. For most players the question is whether the extra speed and memory justify the premium.

The verdict

Our pickNVIDIA

RTX 4090

75Score
$1,599MSRP24 GB450 WIndex 82 at 1440p

The previous flagship, now out of production. It remains a top-tier 4K card with 24 GB of memory, but it lacks DLSS 4 Multi Frame Generation and is only worth considering at a genuine discount on the second-hand market.

NVIDIA

RTX 5090

70Score
$6,59232 GB575 WIndex 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.

RTX 4090 comes out ahead of RTX 5090.

  • RTX 5090 is about 22% faster than RTX 4090 at 1440p.
  • RTX 5090 has 32 GB of VRAM against 24 GB.

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.

Prices and where to buy

Each price carries its source and date, or is labelled as a launch MSRP. The retailer page is the authority on today's price.

RTX 4090

$1,599MSRP

Launch MSRP in US dollars, as set by the manufacturer at release. CompareYourGPU has no verified street price for this card, so this is a reference point rather than what it sells for today. The Amazon store the link opens depends on your location and charges in its own currency (US dollars, euros or pounds): expect a different figure there, and treat that page as the authority on what the card actually costs.

This card is out of production, so street prices are especially unpredictable.

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.

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.

Price, verified where available.

A card with a verified current price is shown at that price, a dated snapshot; a card without one is shown at launch MSRP. Street prices move, so check the retailer.

Which one should you buy?

The short version: the RTX 5090 is faster, but the RTX 4090 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.

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 4090

Delivers the most performance per dollar of the cards compared, at $1,599. 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 4090

Carries 24 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 4090

Best performance per watt of the cards compared, drawing 450 W. That means less heat, quieter fans and less pressure on your power supply.

Best overall

RTX 4090

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 4090 vs RTX 5090: common questions

How much faster is the RTX 5090?
About 22% at 1440p on CompareYourGPU's estimated index (100 against 82) and about 28% at 4K (100 against 78). It also has 32 GB of GDDR7 against 24 GB of GDDR6X, and a 512-bit bus.
What does it cost to run?
The RTX 5090 is rated at 575 W against the RTX 4090's 450 W. It needs a power supply and a case built for that, and its 16-pin connector must be fully seated.
Is the RTX 4090 still worth it?
It remains very fast, but it is discontinued, so you would be buying used or from remaining stock. The RTX 5090 adds Multi Frame Generation and more headroom, at a much higher price.
