ASUS ROG-STRIX-RTX3080-O12G-GAMING

The ASUS ROG Strix RTX 3080 O12G is a beast of a card for 1440p and 4K gaming, with 12GB of GDDR6X and strong ray tracing. It's power hungry at 390W and takes up nearly three slots, so check your PSU and case first. Prices range from $470 to $1,099, so shop around. At the low end, it's a great deal. At the high end, skip it and buy something newer.

The PassMark G3D score of 25,040 puts this card in the upper tier of our database. That's well above average for rasterization, though not quite at the top of the charts anymore. For context, the newer RTX 40 and 50 series cards have pushed past this, but the 3080 O12G still delivers smooth 1440p gaming at high refresh rates. You're looking at 100+ fps in most competitive titles and 60+ fps in demanding AAA games at 1440p with settings cranked up.

Ray tracing is where this card really shines for its generation. The 2nd gen RT cores and 48 RT units put it in the 75th percentile for ray tracing performance. That's strong, especially when you pair it with DLSS. The 12GB of GDDR6X memory means you won't hit VRAM limits at 1440p or even 4K in most games. The 30.6 TFLOPS of FP32 compute is solid, though the AI and LLM scores are more middle of the pack. If you're doing machine learning work, this isn't the card for you. But for gaming, it's still a beast.

The MSI Ventus RTX 5070 Ti is the elephant in the room. It's a newer card with 16GB of VRAM and better efficiency, though it typically costs more. If you're building a new system from scratch, the 5070 Ti makes more sense for future-proofing. But if you're upgrading an existing rig and find the 3080 O12G at a good price, the performance gap isn't as huge as the generation gap suggests. The Gigabyte AORUS RTX 5080 is in a completely different league, both in performance and price. That's for people who want 4K at max settings without compromise.

The ZOTAC APOCALYPSE and PNY OC cards are also newer options worth considering. They offer better efficiency and newer features like AV1 encode, which the 3080 does have actually, but with less mature driver support. The Sapphire NITRO+ is an AMD card, so that's a different conversation entirely. If you're team red, it's worth a look, but the 3080 O12G's ray tracing and DLSS support give it an edge in games that use those features heavily.

The value story here is complicated. Prices in USD range from $470 to $1,099 across two listings, which is a massive spread. The best deal we're seeing is on Amazon at the lower end of that range. At $470, this card is a steal for 1440p and 4K gaming. At $1,099, you're paying way too much when newer cards offer better performance per dollar. The affordability percentile sits at 24th, which means this card is more expensive than most GPUs in our database. That's not surprising for a premium ROG Strix model, but it's worth knowing.

If you can find this card under $600, it's a solid buy. The 12GB of VRAM gives it more longevity than the 10GB 3080, and the build quality is genuinely excellent. But once you cross $700 or $800, you should seriously consider saving for a newer card or looking at the used market. The refurbished listings on Newegg are worth checking too, just make sure you're getting a warranty.

The ASUS ROG Strix RTX 3080 O12G is one of those cards that still turns heads a few years after launch. It's the 12GB version of the 3080, which means it got a memory bump over the original 10GB model and a slightly wider 384-bit bus. That gives it 912 GB/s of memory bandwidth, which is still plenty for 1440p and 4K gaming. ASUS went all out with the cooler, a 2.9-slot triple fan design that's built like a tank. This is a card for people who want flagship-tier build quality and don't mind paying a bit extra for the ROG branding.

Who's this for? Honestly, it's for someone upgrading from a GTX 10-series or RTX 20-series card who wants a big jump in performance without jumping to the latest generation. The 8960 CUDA cores and 1890MHz boost clock put it well above the vanilla 3080 and just below the 3080 Ti. If you're gaming at 1440p or 4K and want ray tracing without your framerate falling off a cliff, this card still holds up. It's also a solid pick for streaming while gaming, thanks to the NVENC encoder and that extra VRAM headroom.

But here's the thing. This is a power-hungry card. 390W TDP, three 8-pin connectors, and ASUS recommends a 750W PSU minimum. That's not a typo. You'll want a quality 850W unit to be safe, especially if you're running a high-end CPU alongside it. The card is also 319mm long and takes up nearly three slots, so check your case clearance before you click buy. It's a big boy.

If you're gaming at 1080p, this card is overkill. You'll be paying for performance you can't see, and the 390W power draw means higher electricity bills for no benefit. A mid-range card like an RTX 4060 or RX 7600 will max out 1080p at a fraction of the cost and power. If you're doing AI or machine learning work, the 3080 O12G's AI performance is mediocre. The 12GB of VRAM is limiting for larger models, and the tensor core performance falls behind newer cards. Look at something with 16GB or more VRAM, like a used RTX 3090 or a newer 40-series card.

If you have a small case or a weak power supply, this card is going to be a headache. The 2.9-slot design and 319mm length won't fit in many mid-tower cases, and the triple 8-pin power requirement means you might need a PSU upgrade. By the time you factor in a new case and PSU, you could have bought a newer, more efficient card that drops right in.

For 1440p gamers upgrading from an older card, the ROG Strix RTX 3080 O12G is still a fantastic choice. The 12GB of VRAM, strong ray tracing, and excellent cooling make it a card that'll keep you happy for years. Just make sure your power supply and case can handle it. If you're building a new system and have the budget, a newer card like the 5070 Ti will serve you better in the long run. But for a drop-in upgrade at the right price, this Strix is hard to beat.

If you're gaming at 1080p, this card is overkill. You'd be better off with something cheaper and more efficient. And if you're doing AI or machine learning work, the 3080 O12G's AI performance is mediocre at best. Look for a card with more VRAM and better tensor core performance. But for pure gaming, especially with ray tracing and DLSS, this card still delivers.
