To provide the necessary power, the TUF Gaming GeForce RTX 4090 uses the PCIe 5.0 standard’s new 16-pin power connector, which supplies a robust power delivery system, with capacitors rated for 20K and a spread of high-current power stages arranged in a 10+4 configuration. In addition, our Auto-Extreme manufacturing process offers robust longevity that lives up to the TUF name, so you can be confident your top-tier card will power through games for years to come. If price is your main concern, no matter which way you go, you're going to be spending less on the RTX 4070 Ti, and the RTX 4070 Ti has a better price-to-performance value than the RTX 4080, overall. Finally, most gaming laptops have a dual fan cooling system, but the G18 was able to push the performance envelope even further with the introduction of a third fan that helps keep the GPU and VRAM cool. Paired with seven heatpipes and Conductonaut Extreme liquid metal on both the CPU and GPU*, the G18’s cooling system is a marvel of engineering. *Conductonaut Extreme liquid metal is applied to the GPU on models with an RTX™ 4080 GPU only

On a casual day of use, including Chrome, Photoshop and some Spotify listening, the efficiency cores aren’t really doing that much, as I make it through from 9 a.m. to roughly 1 p.m. before I need to plug in or lose my work. That’s considerably longer than my past experiences with gaming laptops, and I’m fairly confident you’ll see that reflected in the impending results. Having bought this car, it installed straight away and Nvidia's software ran perfectly fine, (after removing AMD software), and it runs all my games flat out on full settings. The minimum power required for a RTX 4080 16GB is 750W, although we recommend a higher wattage PSU for comfortable overhead. You’ll also require 3x PCIe 8-pin connectors OR a 450W or greater PCIe Gen 5 cable to connect the PSU to this GPU. Can I stream games with the NVIDIA GeForce RTX 4080 16GB?

Graphics Features

The ROG Strix GeForce RTX 3090 ARGB tail light works with Aura Sync to offer customized lighting , while two FanConnect II headers allow control of case fans via GPU temperature readings through the new ASUS GPU Tweak III software. For users that do not want to tweak too much, the Dual BIOS switch allows one to choose between a maximum performance mode and a quieter mode. Equipped with the ASUS 0dB technology, the card can perform at quiet decibel levels at various loads.

Speaking of power: this is an absolute monster of a gaming card, so we’ve included a 12+4 phase system comprising 70A power stages. With two power stages per phase fueling the GPU, that’s a total count of 24+4. The digital controller on board offers higher precision when detecting power, as well as better power conversion and balancing for less noise and signal interference. With a quality power supply in place (like our ROG Thor 1200P2), you should have no problem driving this beast of a graphics card, and with native 16-pin PCIe support, you can do it without any adapters required. Right up front, the Nvidia RTX 4070 Ti has a much lower MSRP than the RTX 4080, so the RTX 4080 would seem to have an uphill battle when it comes to price. But that's not the whole story. The GeForce RTX 4090 heatsink design has been redesigned, with a new vapor chamber and 30% more surface area for heat dissipation than the previous generation ROG Strix GeForce RTX 3090. The patented vapor chamber design adds milled channels underneath the heatpipes, allowing more heat to efficiently transfer to the four 8 mm and three 6 mm heatpipes and travel to the heatsink fins. When subjected to a 500-watt thermal load, this potent pairing allows for 5 °C cooler temperatures than a conventional vapor chamber design.

Why go for RTX 4090? 4080 gets uncomfortably close…

It will probably be another five or six years before any games come out that list an RTX 4080 as its recommended spec, much less its minimum, so this card will likely burn out from extended use long before you'll run up against a game you can't play at 4K and get a great framerate, especially with DLSS 3. And of course, the switch to Nvidia’s Advanced Optimus makes extracting the best possible performance out of the Scar 16 a cinch. Basically, it’s an automated MUX Switch to connect the display directly to the dGPU through software, and (as the name suggests) HDR. ASCEND TO NEW HEIGHTS WITH THE NEW GEFORCE RTX 4090 AND RTX 4080 CARDS FROM ROG STRIX AND TUF GAMING Finally, like our other ROG cards, the Strix GeForce RTX 4090 was built with our Auto-Extreme manufacturing process that minimizes human intervention, so you can expect reliable long-term performance right out of the box. Forge ahead of the game with the TUF Gaming GeForce RTX 4090 Powered by the new ultra-efficient NVIDIA Ada Lovelace architecture, the 3rd generation of RTX, GeForce RTX 40 Series GPUs are beyond fast, giving gamers and creators a quantum leap in performance, neural rendering, and many more leading platform capabilities. This massive advancement in GPU technology is the gateway to the most immersive gaming experiences, incredible AI features and the fastest content creation workflows.

Here, Blender Cycles render a scene as many times as it can in a set time limit using Nvidia's CUDA GPU instruction set. The results speak for themselves, as the RTX 4080 renders 3D scenes about 30% faster than the RTX 4070 Ti on average. While we haven't tested it specifically, you can probably expect the same kind of performance in other rendering applications like Maya as you'll find in Blender. But if AI frame generation is the only place where the 4090 pulls ahead, it can be argued that these GPUs are a lot closer than Nvidia suggests in its marketing material. For you, that means you can save big and still get an awesome gaming experience. Asus ROG Strix Scar 16 performance You get two fan connectors on the end of the card, for running installed case fans in conjunction with the cards own fans, but I have not bothered with this.

RTX 4080's are very power efficient and you will get away with a 850w PSU. This card in particular draws a lot less than my AMD card did when gaming (65+w less). However, Nvidia does have some extras that AMD is unlikely to match in the near term. For example, the Deep learning and AI horsepower in RTX 4080 far surpass what AMD intends to offer. If we've got the figures right, AMD's FP16 and INT8 throughput will be less than a third of the RTX 4080. All of Strix’s must-have features are all here as well: Choose between performant and quiet modes with a Dual BIOS switch, connect case fans to two FanConnect II headers, and light up a rig with a ring of ARGB tail lights compatible with Aura Sync. Meanwhile, reliable power delivery and time-tested build quality through the Auto-Extreme manufacturing process mean this card is ready to stand with users for years to come. For a more accessible card that still screams Strix, the ROG Strix GeForce RTX 4080 12GB is not to be trifled with. The RTX 4080 16GB GPU with its dual AV1 NVIDIA Encoders is an excellent GPU to stream all your favourite titles. How many monitors can I use with a RTX 4080 16GB GPU? The power of the AD103 GPU in the RTX 4080 shines through in our creative benchmark suite, especially in the Blender 3.4.0 tests.
