A data warning first. The 3DMark Time Spy figures in our graphics-card data are not all measured the same way: the two ASUS Astral rows carry published graphics scores, while the other cards sit 25-30% lower, in the range you get from Time Spy's overall score. Two metrics in one column. The clearest symptom is that our Astral RTX 5080 OC and our reference RTX 5090 carry the same number, which cannot be right either way.
We are re-sourcing the column from a single database. Until then, do not read the Astral cards' positions as a performance claim, and compare the reference cards against each other rather than against them. Everything else on this page — cores, memory, power, physical size — is manufacturer data and is sound.
Beyond that, the specification that decides more builds than price is physical size. Every figure below is the live computed Mars Score.
The reference flagship: NVIDIA GeForce RTX 5090
Mars Score 84.2 at $1,999. 21,760 CUDA cores, 32 GB of GDDR7 on a 512-bit bus — twice the memory bandwidth of anything else here — 575 W, and a 2-slot, 304 mm card.
That last part matters: the Founders card fits cases the ASUS Astral ($2,399, 357 mm and 4 slots) does not. Four slots is most of a mid-tower's expansion space.
Who should buy it: people doing 4K at high refresh, or running local models where 32 GB of VRAM is the whole point.
Best value at the high end: AMD Radeon RX 9080 XT
Mars Score 79.0 at $1,099. 24 GB of GDDR7, a 3,100 MHz boost — the highest clock on this page — and 330 W against the 5090's 575 W, which means a 850 W power supply rather than a 1,000 W one.
It gives up DLSS. In 2026 that is still a real gap for ray-traced games, and FSR has closed much of it elsewhere.
Still excellent: NVIDIA GeForce RTX 4090
Mars Score 78.0 at $1,599. 16,384 cores, 24 GB, 450 W, 304 mm, 3 slots. Previous-generation, and if you find one below $1,300 it is the best price-to-performance card in this top ten.
The mid-high field
AMD Radeon RX 9080 (74.9, $899) offers 20 GB of VRAM at 290 W — the lowest power draw here — which makes it the easiest high-end card to fit into an existing system.
NVIDIA GeForce RTX 5080 (71.4, $999) is 16 GB, 360 W, and a 2-slot 304 mm card — the most compact current-generation high-end option.
Between them: the AMD has 4 GB more VRAM and draws 70 W less; the NVIDIA has DLSS. At a $100 difference this is a genuine coin-flip and depends on which games you play.
Two ways to spend $999
AMD Radeon RX 7900 XTX (70.5) gives 24 GB of GDDR6 — 50% more VRAM than the 5080 at the same price — at 355 W in a 287 mm, 2.5-slot card.
NVIDIA GeForce RTX 4080 SUPER (69.7) gives 16 GB of GDDR6X at 320 W with DLSS.
If you run large local models, the 24 GB card wins outright. If you play ray-traced games, the NVIDIA does.
Best card most people should buy: NVIDIA GeForce RTX 5070 Ti
Mars Score 68.1 at $749 — last in this top ten and the sensible purchase on it. 16 GB of GDDR7, 300 W, 267 mm and 2 slots: the shortest card here, the one that fits anything, and the one that does not require a new power supply.
Who should buy it: anyone gaming at 1440p, which is most people.
How to choose, in four questions
- Measure your case first. 267 mm to 357 mm, 2 slots to 4. A card that does not fit is not a fast card.
- Check your power supply. Recommended figures here run 750 W to 1,200 W. Add a PSU to the budget before deciding.
- VRAM for work, DLSS for play. 16 GB is enough for gaming; local AI wants 24 GB or 32.
- Ignore the factory-overclock premium. Even with correct data, an OC card is a few per cent faster and often much larger — see the Astral 5090 at 357 mm and 4 slots against the reference card's 304 mm and 2.
