ASUS TUF-RTX4090-O24G-OG-GAMING

The ASUS TUF RTX 4090 OG OC is a 4K gaming beast with 24GB of VRAM and top-tier performance, sitting at the 97th percentile for rasterization. It's power-hungry at 450W and efficiency is mediocre, but the TUF cooler keeps it manageable. Prices range from USD 3,200 to USD 4,999, so shop carefully. If you need maximum VRAM and raw power, it's still a great buy at the low end. Most people should consider the RTX 5080 instead.

Let's talk numbers. The PassMark G3D score of 38,098 is one of the highest we've seen in our database. For context, that puts it in the 97th percentile for rasterization. In plain English, this card crushes 4K gaming. You're not going to find many titles that make it sweat at 1440p, and even 4K with high refresh rates is on the table. The 24GB of VRAM is a big part of that. At the 93rd percentile for memory capacity, it's got enough headroom for texture-heavy games and modded setups that would choke lesser cards.

The compute side is equally impressive. 32.98 TFLOPS of FP32 performance lands at the 95th percentile. That's not just gaming muscle, it's useful for AI workloads, rendering, and other GPU-accelerated tasks. The 4th-gen Tensor cores and 3rd-gen RT cores mean DLSS 3 and ray tracing are handled with ease. Our ray tracing score puts it at the 89th percentile, which is still excellent even if it's not the absolute top. The one area where this card shows its age is efficiency. At 450W TDP and a 42nd percentile efficiency rating, it's a power-hungry beast. You'll need an 850W power supply minimum, and your electricity bill will notice.

The RTX 4090 TUF OG sits in an awkward spot right now. Against the Gigabyte AERO RTX 5080, you're looking at a newer architecture with better efficiency and DLSS 4 support. The 5080 has less VRAM at 16GB, but for most games that's still plenty. The 4090 wins on raw memory bandwidth and capacity, which matters for 4K texture packs and some workstation tasks. But the 5080 is often cheaper and draws less power. If you're building a new system today, the 5080 is probably the smarter buy for most people.

Against the MSI Ventus RTX 5070 Ti, the 4090 is clearly faster. No contest there. But the 5070 Ti is dramatically cheaper and still handles 4K gaming well with DLSS. The ZOTAC AMP Extreme Infinity RTX 5080 is another competitor that offers similar performance to the 4090 in many games while being more efficient. The Sapphire NITRO+ is an AMD option that's worth a look if you don't care about ray tracing or DLSS. The 4090's main advantages are the 24GB of VRAM and the sheer compute power. If you need those, nothing else in this price bracket touches it. If you don't, you're paying a premium for specs you won't use.

Here's where things get messy. The price spread on this card is wild. In the US, we're seeing listings from USD 3,200 all the way up to USD 4,999. That's a USD 1,799 difference for the same GPU. If you're buying in the US, the lower end of that range is the only one worth considering. Paying close to five grand for a last-gen card is a tough pill to swallow. In Canada, the spread is even crazier, CAD 2,900 to CAD 6,960. That's a CAD 4,060 gap. The CAD 2,900 listing is actually a decent deal if you can find it in stock.

The problem is that this card is competing against RTX 50-series options that are often cheaper and more efficient. The Gigabyte AERO RTX 5080, for example, is a newer card that trades blows in some scenarios while drawing less power. The MSI Ventus RTX 5070 Ti is another option that's significantly cheaper and still delivers strong 4K performance. So the value proposition here really depends on what you can actually find it for. At the low end of the US price range, it's a premium but justifiable purchase for someone who wants maximum VRAM and raw power. At the high end, you're getting fleeced.

The ASUS TUF Gaming RTX 4090 OG OC Edition is a weird one. It's a flagship card from the last generation wearing a familiar outfit. ASUS basically took the RTX 4090's Ada Lovelace silicon and stuffed it into the same size and shape as their RTX 30-series TUF cards. If you had a TUF 3080 or 3090 and loved the fit, this thing will feel like coming home. Just with way more horsepower under the hood.

Who's this for? Someone who wants the absolute best 4K gaming performance available right now and doesn't mind paying a premium for it. The 24GB of GDDR6X memory and 16,384 CUDA cores put it in a class of its own for rasterization. Our database has it sitting at the 97th percentile for raw gaming performance. That's not just good, that's top of the charts. If you're chasing max settings at 4K with ray tracing on, this card doesn't flinch.

But here's the thing. This is a last-gen flagship selling at next-gen prices. The RTX 50-series cards are out there now, and some of them are cheaper. So the real question isn't whether this card is fast. It obviously is. The question is whether the price makes sense when newer options exist. We'll dig into that.

If you're gaming at 1440p or lower, this card is massive overkill. You'd be paying a premium for performance you'll never see. A mid-range card like the RTX 5070 Ti or even a 4070 Super will max out your monitor and leave hundreds of dollars in your pocket. Same goes for anyone building a small form factor PC. At 326mm long and 3.2 slots thick, this thing won't fit in most ITX cases.

Also skip it if you're planning a custom water cooling loop. The OG PCB design means many popular waterblocks don't fit, which is a real headache if you're spending this much on a card. And if you're sensitive to power draw or electricity costs, the 450W TDP and mediocre efficiency rating should give you pause. The RTX 5080 offers similar performance in many games while drawing significantly less power.

If you're a 4K gamer who wants to max out every setting and never think about VRAM limits, this card is still a monster. The 24GB of GDDR6X and 16,384 CUDA cores mean you can throw anything at it and it'll chew through it. The TUF cooler is solid, the build quality is excellent, and the familiar form factor is a nice touch for anyone upgrading from an RTX 30-series TUF card. Just make sure you're getting it at the low end of the price range. At USD 3,200, it's expensive but defensible. At USD 4,999, you're paying scalper prices for a card that's been out for a while.

For most people, though, I'd point you toward the RTX 5080 or even the 5070 Ti. They're newer, more efficient, and offer better price-to-performance. The 4090's main selling point is that 24GB of VRAM, and unless you're doing heavy AI work, 4K modding, or professional rendering, you probably don't need it. If you do need it, this card is one of the best ways to get it. Just be prepared for the power draw and the size. This thing is a chonker.
