Test bench

Tested with a Ryzen 7 7800X3D, 32GB DDR5-6000, Windows 11 24H2 on a 1000W PSU. Latest driver at time of testing.

Build compatibility
What your PC needs
Power supply
750W is the official recommendation and the realistic floor. With a high-end CPU, step up to 850W or 1000W for headroom against transient power spikes.
!
Case clearance
Triple-fan ROG Strix cooler is chunky. Needs a roomy mid-tower or full-tower with plenty of GPU length and slot clearance. Won't fit ITX or compact mATX builds.
Motherboard slot
Standard PCIe 4.0 x16 slot. Works on PCIe 5.0 boards with no performance difference at this card's bandwidth.
!
12VHPWR connector
Uses the 12VHPWR power connector. Seat it fully home and avoid sharp bends near the plug. A native cable from a modern PSU is preferable to the included adapter.
CPU pairing
Pairs well with a Ryzen 7 7800X3D, Ryzen 9 7950X, Core i7 14700K or better. Older CPUs will bottleneck the card noticeably at 1440p and below.

Who this is right for

Picture yourself in these scenarios. How well does this fit?

Premium 4K showpiece builder
Building a showpiece PC where the GPU is part of the visual identity. ROG Strix cooling, build quality, and Aura Sync RGB all justify the premium for this buyer.
Good fit
Acoustic-focused 4K gamer
Cares deeply about a quiet PC. The ROG Strix triple-fan cooler is among the quietest 4080 partner cards, keeping noise minimal under sustained 4K gaming load.
Good fit
Multitasking creator
Uses the card for gaming plus 3D rendering or video work. Capable for both, though current-gen cards offer better encoder performance and DLSS 4 support.
Okay fit
Full-RRP current-gen buyer
Shopping new at current prices. The RTX 5080 or 4080 SUPER both make more sense for similar money than the original 4080.

What every spec actually means

Numbers translated into real-world impact

vram_gb16

Plenty for 4K gaming today, even with ray tracing and heavy texture packs enabled. Won't choke the way 12GB cards already do in some recent releases, though 24GB cards have more long-term headroom.

tdp_w320

Substantial power draw, so a quality 750W PSU is the minimum recommendation. Older or weaker power supplies will trip protection circuits under heavy load, especially with a power-hungry CPU.

cuda_cores9728

Strong CUDA core count for the original 4080. The later 4080 SUPER bumped this to 10240 cores for a small performance increase, worth a slight discount on the original 4080.

boost_clock_mhz2505

Factory-overclocked boost clock above the reference 4080's 2505 MHz. Real-world boost clocks under typical gaming load tend to push slightly higher with premium ROG Strix cooling.

memory_bandwidth_gbps717

High bandwidth thanks to 22.4 Gbps GDDR6X memory on a 256-bit bus. Comfortable for 4K gaming, only the heaviest path-traced workloads start to push the bus.

psu_recommendation_w750

Realistic floor recommendation. With a power-hungry CPU, step up to a quality 850W unit. Don't try to scrape by with a 650W PSU here, the transient power spikes will trip protection.

Common questions

The things people ask before buying this product

Is the RTX 4080 still worth buying over the 4080 SUPER?

Only at a meaningful discount. The 4080 SUPER has slightly more cores at typically lower launch pricing. If the original 4080 is genuinely cheaper, the small performance gap doesn't matter much, otherwise pick the SUPER.

Is the original RTX 4080 still worth buying in 2026?

Only at a clear clearance discount. The RTX 5080 or 4080 SUPER both make more sense for similar money. At a meaningful discount the original 4080 remains a strong 4K card.

Is the ROG Strix 4080 worth the premium?

If acoustics, premium build, and Aura Sync RGB matter to your build, yes. Gaming performance over cheaper TUF Gaming or Dual variants is small, so the premium pays for cooling and aesthetics.

What PSU do I need for the ROG Strix 4080 OC?

Nvidia recommends 750W and that's the realistic floor. With a power-hungry CPU like a Core i9 or Ryzen 9, step up to a quality 850W unit. Don't try to scrape by with a 650W PSU here.
