RTX 4080 GPUs are just as big as RTX 4090s


With the impending arrival of Nvidia’s GeForce RTX 4080 on November 16, some of Nvidia’s AIB partners have already started posting published product pages of its GeForce RTX 4080 models, including Asus, Gigabyte, and Galax. Unfortunately, not all of the AIB partner listings are here, but the few we have should give us a good overview of the GeForce RTX 4080 form factor. Also expect the GeForce 4080 to appear in our list of best graphics cards once Ada Lovelace graphics card launched.

It’s worth mentioning that we’re talking about the GeForce RTX 4080 16GB variant when we talk about the GeForce RTX 4080. With Nvidia’s final rejection of the GeForce RTX 4080 12GB, the other 16GB terminology is no longer necessary. However, some AIB partners still seem to use this badge to save on e-waste so they can continue to use the GeForce RTX 4080 16GB enclosures they created before the GeForce RTX 4080 12GB was phased out.

The GeForce RTX 4080 is second only to the GeForce RTX 4090, with 9,728 CUDA cores and a maximum boost clock of 2.51 GHz. Memory specs include 16GB of GDDR6X memory running on a 256-bit wide bus. The GPU’s reference power rating is 320W, which comes from a 16-pin power connector.

Asus has two RTX 4080 versions, including the RTX 4080 ROG Strix (opens in a new tab) and the RTX 4080 TUF Gaming. (opens in a new tab) Both models are identical to their RTX 4090 counterparts, including cooler design language and physical board size. The ROG model retains the same red, black, and blue theme and features a matte black GPU shroud and silver text. The TUF follows suit, with a gray finish and an RGB light bar in the top right.

It looks like Asus has repurposed the RTX 4090 coolers on its RTX 4080s. For future Asus RTX 4080 owners, this will be ideal for overclocking since the cooler keeps the GPU core and memory exceptionally cool. The only downside is the board size, which will make case compatibility an issue. But hopefully we should get some lower-end Asus RTX 4080 builds – such as the Dual series, which will cater to the “compact” PC market.

Gigabyte’s listings are more enticing, with six different variants including Eagle, Aero, and a full-fledged waterblock version that the RTX 4090 variants lack.

The five SKUs include the Gigabyte GeForce RTX 4080 Eagle, Eagle OC, RTX 4080 Aero OC, RTX 4080 Gaming OC, Aorus RTX 4080 Xtreme Waterforce (AIO version), and the RTX 4080 Xtreme Waterforce WB.

The RTX 4080 Eagle variants represent Gigabyte’s budget RTX 4080 graphics cards and feature a new, redesigned aesthetic. Gone is the jagged-edged cooler shroud, replaced by a standard rectangular shroud design with a gray color scheme accompanied by blue and white color accents.

Unfortunately, the card isn’t that small, measuring just under four PCIe slots thick, with a length of 342mm. On the other hand, the height is quite large, with a size of 40mm – well above that of PCIe slots, so compatibility of this case will be problematic on smaller ATX, microATX and Mini-ITX chassis. .

The RTX 4080 Aero shares similar specs with the Eagle, adopting the same overall form factor and triple-fan cooler design. But identical to previous Aero cards, the color scheme has been changed to white and silver. Additionally, the card shroud features a matte white finish and two silver accents between the three fans in the middle.

Like the Asus models, Gigabyte’s RTX 4080 Gaming and Gaming OC video cards share the exact same dimensions as their RTX 4090 counterparts. The GPUs also share the same cooler design, with a matte gray finish on the shroud and RGB light rings inside the triple fan cooler layout.

Again, it almost looks like Gigabyte is putting RTX 4090 coolers on top of the 4080 builds in this case, but the 4080 gaming OC is different – just about slightly. The width is 0.2mm shorter (yes, that’s what the spec sheet says), but the 4080 Gaming OC is 2mm longer for some reason.

There is nothing to note about the water block builds other than the fact that you can get the RTX 4080 in both a water block build and an AIO variant. The differences between the 4090 versions are minimal at best.

Galax’s RTX 4080s feature an ST and SG model, with the SG versions representing a factory model.

The Galax RTX 4080 ST/SG features a black color scheme with a strong emphasis on RGB lighting. The shroud sports matte and gloss black finishes, bringing out the RGB lighting on the board. Enlightenment is everywhere on the map; it’s between the triple fan cooler design, around the edges and sides. Moreover, it features design queues from a flash.

Compared to the RTX 4090 models, the RTX 4080 versions are aesthetically identical (like the Asus models), but there are noticeable differences in size. The 4090 models are 74mm thick, while the 4080 models are 66mm thick. As a result, they make the 4080s slightly thinner.

So it seems from these three brands that the GeForce RTX 4080 overall won’t be much smaller than the RTX 4090, despite its drastically different power consumption. This should improve GPU overclocking prowess, but these cards will still share the same case compatibility issues as the RTX 4090.
