With the RTX 3080 already capable of 4K UHD gaming with raytracing, the RTX 3090 has an interesting market position at its $1,499 starting price, which is about 50% higher than the launch price of the RTX 2080 Ti, but exactly 50% lower than the TITAN RTX. 

ZOTAC Gaming GeForce RTX 3090 Trinity OC 24GB GDDR6X review


The ZOTAC GeForce RTX 3090 is 12.5″ long, x 4.75″ in depth and x 2.28″ in height. It comes with the company’s IceStorm 2 cooler that features a long series of aluminium fin-stack heatsinks held together by copper heat pipes, ventilated by three fans that each spin at a speed independent of the others. Flipping over to the back of the card we have a full-cover metal backplate. It has a Zotac Gaming logo which will light up with RGB lighting when the card is powered on.


The ZOTAC RTX 3090 Trinity video outputs include 3x DisplayPorts and a single HDMI port. Again, there is not a USB Type-C port in the newer generation like we saw with the GeForce RTX 2080 Ti. On the top-edge of the card you’ll find another Zotac Gaming, which will also light up with RGB lighting. Right above it you have two 8-pin PCI-Express power connections.

Frame rates – ZOTAC Gaming GeForce RTX 3090 Trinity OC 24GB GDDR6X

Many games will run at over 90 FPS. With the highest details in 4K, nearly all run at over 60 FPS—only Control is slightly below that, but DLSS will easily boost FPS beyond that. With those performance numbers RTX 3090 is definitely suited for 4K resolution gaming. The performance offered by the RTX 3090 is impressive; the Trinity is 45% faster than the RTX 2080 Ti and 72% faster than the RTX 2080 Super. AMD’s Radeon RX 5700 XT is less than half as fast—the performance uplift vs. the 3090 is 217%! AMD Big Navi better be a success.


The temperature target does go from 83C to 87C so perhaps that will get us an extra step or two on the boost. We go ahead and jump the core clock +50Mhz.

The fans sit atop a large aluminum heatsink array. The heatsinks are grouped into three groups with heatpipes connecting them. The heatpipes make direct contact with the GPU for better heat transfer. The heatpipe layout has actually been improved since the last generation as well. You’ll also notice metal around the edge of the card, this is a metal front plate which will help with rigidity and structural integrity.

Power consumption

New to the RTX 3000 series cards are some detailed power measurement readouts available to programs like GPUz. We see the card max out at ~360W, with around 105W of that consumed by the 24GB of GDDR6X itself and roughly 200W consumed by the GPU core. This leaves around 55W that is used by everything else on the board, the fans, lighting, Video output ports, PCIe communications, and inefficiency losses in the various VRM stages. Our system consumed a maximum of 560W from the wall, or around 515W from the PSU itself. 

FireStorm app

FireStorm is pretty much the same application we saw on the RTX 20 series cards from Zotac. When you open it up you’ll see GPU, memory, and fan speeds in real time as well as the current GPU temperature. RGB lighting control is also found in FireStorm by clicking on the Spectra tab. Here we can either link RGB effects on the top edge and back or control them individually. You can select colors, effects, etc.

Nvidia GeForce RTX 3080 Ti


+Superb 4K performance+Nearly an RTX 3090 for less cash+Excellent ray tracing capability


-A lot pricier than the RTX 3080-Power hungry at 350W-Runs pretty hotAdvertisement

With performance close to the RTX 3090 at 4K, the RTX 3080 Ti is as much a gaming graphics card as its progenitor. With a vast bounty of CUDA Cores and speedy GDDR6X memory, this card demolishes any game you can throw at it with relative ease. It’s also more than capable of real-time ray tracing, courtesy of 80 RT Cores.

The RTX 3080 Ti isn’t the mightiest GeForce graphics card that Nvidia makes. That accolade goes to the RTX 3090, by a hair, and will undoubtedly be claimed by the RTX 3090 Ti once that arrives. Though when all is said and benchmarked, it is the uber high-end RTX 3080 Ti that we’d recommend to any PC gamer looking to go all out on their next build.

The reason we don’t rate this card higher up in our list of the best graphics cards, however, is down to its price. Launching at $1,200, it’s only a stone’s throw away from the $1,499 RTX 3090. Massively inflated pricing, or lack of stock, notwithstanding.
