The Best RTX 4090 Graphics Cards
Five partner RTX 4090 cards compared on cooler design, boost clock and thickness, since every model shares the same GPU and 24GB of memory.
By The PC Journal editorial team
12 min read5 products evaluated
The RTX 4090 was NVIDIA's flagship of the RTX 40 generation, with 24GB of GDDR6X. Because every partner card uses the same GPU, the choice comes down to cooler size, clock speed and price.
Prices for the RTX 4090 vary widely now that it is out of production, so compare listings before you buy. We compared listed specifications from the card makers and retailer listings; we did not benchmark these cards.

How We Chose These RTX 4090 Cards
Each pick was assessed across 4 criteria weighted for real-world use.
- Fit
- We recorded length and slot thickness where the maker lists them, plus low-profile and SFF-Ready status.
- Price tier
- We grouped picks by price at the time of writing rather than by listed clock speed.
- Power
- We noted the power connector and recommended power supply where listed.
- Cooling and extras
- We checked cooler design, fan-stop modes, dual BIOS, support brackets and display outputs.
What to Look for in an RTX 4090 Card
Key buying criteria so you get the right fit the first time.
Check length and thickness
Partner cards of the same GPU can differ by several centimetres. Compare the card's length with the case's GPU clearance, allowing for front fans or a radiator, and check how many slots it covers.
Plan the power connector and PSU
Cards use one or two 8-pin PCIe plugs or a single 16-pin 12V-2x6 plug. Confirm your power supply has the right cables and meets the maker's recommended wattage.
Compare upscaling and encoders
NVIDIA cards support DLSS, AMD cards FSR and Intel cards XeSS. Each game supports a different mix, so check the titles you play.
Streamers should also compare hardware video encoders.
Pair it with a balanced CPU
A fast card with an old CPU can stall at high frame rates, especially at 1080p. At 4K the GPU does most of the work, so the CPU matters less.
Match the card to your monitor
Resolution and refresh rate decide how much GPU you need. A 1080p screen at 144Hz asks far less than 1440p at 165Hz or 4K.
Buy for the monitor you use now or will buy soon, not for a resolution you may never run.
Treat 8GB of VRAM as the floor
Some recent games already push past 8GB at high texture settings. Cards with 12GB or 16GB give more room, especially at 1440p and above.
Two versions of the same chip can differ only in memory; check the capacity in the exact model name.

Frequently Asked Questions
Do I need a GPU support bracket?
Long, heavy cards can sag and stress the slot. Some come with a support stand or bracket; otherwise one is inexpensive to add.
Will a PCIe 5.0 card work in a PCIe 4.0 or 3.0 slot?
Yes, the interface is backward compatible. Cards with a narrow x8 link can lose some performance on PCIe 3.0 boards.
Do partner cards of the same GPU perform differently?
Only slightly. Factory overclocks add a few percent at most; cooling, noise, size and price differ more.
Should I choose AMD or NVIDIA?
Compare price and memory at your budget first, then features such as DLSS or FSR support in your games and hardware encoding if you stream.
Is an 8GB graphics card still enough?
For 1080p with tuned texture settings, often yes. For 1440p or high textures in new games, 12GB or 16GB is safer.
Will my CPU hold the card back?
It depends on resolution and the games you play. At 1080p and high refresh rates the CPU matters more; at 4K the GPU sets the limit.
Bottom Line
The PNY Verto is the most affordable way into an RTX 4090 here, and the ASUS TUF adds a stronger cooler. Choose MSI's Gaming Slim for a thinner card, and the ROG Strix only if you want the most elaborate cooler.
