GALAX GeForce RTX 4080 SG Review – The Quad Cooler Returns!

NVIDIA GeForce RTX 40 Series - GeForce RTX 4080

The NVIDIA GeForce RTX 4080 will use 76 SMs of the 84 SMs for a total of 9728 CUDA cores. The GPU will come packed with 64 MB of L2 cache and a total of 112 ROPs which is simply insane. The clock speeds for the graphics card are rated at 2210 MHz base and 2510 MHz boost clocks and we have already seen over 3 GHz speeds with overclocking which you can read more about here.

As for memory specs, the GeForce RTX 4080 features 16 GB GDDR6X capacities that will be adjusted at 22.5 Gbps speeds across a 256-bit bus interface. This will provide up to 720 GB/s of bandwidth. This is still a tad bit slower than the 760 GB/s bandwidth offered by the RTX 3080 since it comes with a 320-bit interface but a lowly 10 GB capacity. To compensate for the lower bandwidth, NVIDIA could be integrating a next-gen memory compression suite to make up for the 256-bit interface.

• NVIDIA GeForce RTX 4080 16 GB "Official" TBP - 320W
• NVIDIA GeForce RTX 3080 12 GB "Official" TBP - 350W

As far as the power consumption is concerned, the TBP is rated at 320W. The card will be powered by a single 16-pin connector which delivers up to 600W of power. Custom models will be offering higher TBP targets.

NVIDIA GeForce RTX 4080 Graphics Cards Performance

As for the performance of these monster GPUs, NVIDIA shared the computational and gaming performance figures and it looks like the GeForce RTX 4080 will be sitting slightly ahead of the GeForce RTX 3090 Ti with around 50 TFLOPs of Compute power.

Just for comparison's sake:

• NVIDIA GeForce RTX 4090: 83 TFLOPs (FP32) (2.5 GHz Boost clock)
• NVIDIA GeForce RTX 4080: 49 TFLOPs (FP32) (2.5 GHz Boost clock)
• NVIDIA GeForce RTX 3090 Ti: 49 TFLOPs (FP32) (1.86 GHz Boost clock)
• NVIDIA GeForce RTX 3090: 36 TFLOPs (FP32) (1.69 GHz Boost clock)

Based on a boost clock speed of 2.5 GHz, you get up to 49TFLOPs of compute performance and you can definitely squeeze out a lot more with an overclock as we had demonstrated with the RTX 4090. One should remember that compute performance doesn't necessarily indicate the overall gaming performance. Even so, it will be a huge upgrade for gaming PCs and an 8.5x increase over the current fastest console, the Xbox Series X.

This will be a 2x compute performance uplift and a 2x gain in gaming performance as NVIDIA has demonstrated for each graphics card versus its predecessor and this is without even factoring in the RT and Tensor core performance which are expected to get major lifts too in their respective department.  A 2-4x gain over the RTX 3090 & RTX 3090 Ti would be very disruptive.

Gamers should expect 4K gaming to be buttery smooth on these graphics cards and with DLSS, we might even see playable 60 FPS at 8K resolution which is something that NVIDIA has been trying to achieve with its RTX 3090 series BFGPUs for a while now.

NVIDIA GeForce RTX 4080 Graphics Cards Price & Availability

The NVIDIA GeForce RTX 4080 16 GB graphics card will be available starting tomorrow for a price of $1199 US. The card will be available in both Founders Edition and custom graphics card flavors at launch.
