NVIDIA GeForce RTX 3090 Ti 24GB GDDR6X
The 24GB of GDDR6X memory and second-gen RT cores make this card a raw compute powerhouse for 8K rendering and massive AI model workloads. Its 450W TDP and triple-slot cooler demand a high-wattage PSU and spacious case, but the Founders Edition build quality remains a standout. This GPU is best for machine learning researchers and 3D artists who need maximum local VRAM capacity over gaming frame rates.

概要
The 30-Second Version
A 450W dinosaur with 24GB of VRAM that still plays 4K games beautifully, but it's hot, hungry, and overpriced in 2025. Unless you need the memory for work, get a newer card.
Pros & Cons
長所
- 24GB of GDDR6X is still a massive VRAM buffer 92nd
- Top-tier 4K gaming performance, no question 90th
- DLSS and ray tracing support keep it modern 82nd
- HDMI 2.1 cable included in the box 79th
短所
- 450W TDP means you need a serious PSU
- Runs hot and loud, thermal performance is a weak spot
- Three slots and 312mm long, check your case
- Price is brutal for a last-gen card

実証データ
Performance
The PassMark score of 29275 puts this card in rare air, well above average for rasterization and a standout for AI workloads. What surprised us is how the 24GB of VRAM keeps it relevant for creators and 4K texture packs even as newer cards launch. But the thermal story is rough, landing near the bottom of the charts. You'll hear the fans and feel the heat, especially in a smaller case.

vs Competition
Against the ASUS TUF RTX 5090, the 3090 Ti gets smoked in efficiency and modern features, though the 5090 costs even more. The MSI Ventus RTX 5070 Ti and Gigabyte AERO 5070 Ti offer better ray tracing and DLSS 4 support for less money, but they only have 16GB of VRAM. If you're a creator who needs the memory, the 3090 Ti still has an argument. For pure gaming, the newer cards win on efficiency and features.

Value & Pricing
At $2,185 USD, this is a tough sell in 2025. You're paying flagship money for a card that's been superseded by RTX 50-series options with better efficiency and newer features. Unless you specifically need 24GB of VRAM for creative work and find a deal, the value just isn't there.
詳細情報
Overview
The RTX 3090 Ti is the last, loudest hurrah of the Ampere generation. It's a 450W monster with 24GB of GDDR6X that still crushes 4K gaming, but it's also a space heater that makes your power bill nervous. The one thing to know: this card was built to be the absolute best at any cost, and it shows in both the frame rates and the electricity draw.
Common Questions
Q: What power supply do I actually need for this card?
NVIDIA recommends an 850W PSU minimum, but with a 450W TDP and transient spikes, I'd go 1000W or higher if you're running a high-end CPU too. Don't cheap out here.
Q: Can this card handle 4K gaming at high refresh rates?
Yes, it's still one of the best 4K cards from its generation. Expect high frame rates in most titles, especially with DLSS enabled. Just don't expect it to match the newest RTX 50-series in ray tracing.
Q: Is the 24GB of VRAM overkill for gaming?
For most games today, yes. But if you do video editing, 3D rendering, or run heavily modded games with huge texture packs, that 24GB is a genuine lifesaver.
Who Should Skip This
If you're a pure gamer looking for the best performance per watt or the latest ray tracing features, this isn't it. Go grab an RTX 5070 Ti or 5080 instead. If you're on a tight budget or have a smaller case, the 3090 Ti's size, heat, and power needs will drive you nuts.
Verdict
The RTX 3090 Ti is a beast that's past its prime. It still delivers excellent 4K performance and that 24GB VRAM buffer is genuinely useful for creators, but the power draw, heat, and price make it hard to recommend over newer options. Buy it only if you find a steep discount and have a beefy PSU ready.
