Gigabyte RTX 3090 Ti Gaming OC Review: A Historic GPU

Gigabyte’s GeForce RTX 3090 Ti Gaming OC proves that assumption wrong. Don’t get me wrong: it’s freakishly big, absurdly expensive, and hungry for unholy power. But if you’re looking to unlock the best possible performance in a gaming PC, this is the graphics card you’ve always wanted.

The Gigabyte RTX 3090 Ti Gaming OC follows Gigabyte’s previous offerings in this line. You’re seeing a slight 2.4% increase in max boost clock speed over the reference design, which is a small but noticeable difference. Otherwise the difference comes down to the cooler and the size.

This is a comically large graphics card, at 10mm wider and 9mm thicker than even Nvidia’s massive reference design. Gigabyte uses space wisely with three 100mm fans and an extended heatsink, allowing air to pass directly through the cooling device past the PCB and backplate.

As capable as it is, the Gigabyte RTX 3090 Ti Gaming OC doesn’t look too good. It’s a matte black, which is even worse considering it’s the only RTX 3090 Ti design offering from Gigabyte (even from its Aorus brand).

It’s not fancy; it’s boring. This card can look great in some builds, but I imagine most gamers will opt for something like the EVGA FTW3 or MSI Suprim X editions simply because they are flashier.

The main difference is the price. Gigabyte’s model retails for as little as $2, while models like the EVGA FTW000 Ultra are closer to $3. That’s the range for new stock cards, though. Now $2 is $200, but that’s not a huge difference considering the cost of the RTX 200 Ti.

For the RTX 3090 Ti as a whole, it’s a very power-hungry graphics card. It has a roughly 10% increase in clock speed over the base model, as well as a slight increase in core count and memory frequency. This comes with a staggering 100W overhead, pushing the TDP up to 450W.

Nvidia only recommends an 850W power supply, which is a bit of a concern. I wouldn’t use the RTX 3090 Ti with a sub-1W PSU (read our roundup of the best PC PSUs if you need an upgrade).

The RTX 3090 Ti is insanely good at gaming, and Gigabyte’s Gaming OC Edition takes it even further. Overall, the card was 9.8% faster in my benchmarks against the RTX 3090 reference design and 13.2% faster than the RTX 3080 Ti at 4K on Ultra settings. If you want the granular details, you can see my full results in the table below.

I ran all my tests with a Core i9-10900K and 32GB of DDR4-3200 memory. I only included results here in 4K because, let’s be honest, you’re not buying an RTX 3090 Ti for not gaming in 4K. Still, I was surprised to see a difference in some games, even at 1080p, including an 8.5% increase in Red Dead Redemption 2 and a 7.2% increase in Assassin’s Creed Valhalla.

Clearly, the RTX 3090 Ti hits a level of gaming that the RTX 3090 didn’t. For over a year now, I’ve been pushing gamers to choose the RTX 3080 Ti over the RTX 3090 because it’s so much cheaper and has the same performance. The RTX 3090 Ti, especially Gigabyte’s Gaming OC variant, makes a compelling case for buying a gaming flagship.

 

As for the details, the RTX 3090 Ti offered a huge performance boost over the RTX 3090 in all my tests except Forza Horizon 4. At all resolutions, the RTX 3090 consistently outperformed its more expensive Ti variant here.

Still, the RTX 3090 Ti is remarkable. It’s the first card to break 70 frames per second (fps) in Walhalla Assassin’s Creed, and even hit close to 60 fps in Cyberpunk 2077 with everything maxed out.

This performance has been scaled with ray tracing enabled, giving a massive 14% increase in Cyberpunk 2077 on the base model. You’d like to enable Nvidia’s Deep Learning Super Sampling (DLSS), but this demanding test shows how the RTX 3090 Ti can still deliver real gaming benefits.

That was my main concern: the RTX 3090 is already a card designed for professionals, not gamers, so I thought the Ti model wouldn’t offer much of a boost. This does. That 10% increase in clock speed translates to around a 10% increase in gaming, far outpacing the competition and cementing the RTX 3090 Ti as the most powerful GPU you can buy.
