At the very top of the list is Gigabyte’s AORUS GeForce RTX 4090 Xtreme Waterforce 24G. Much like its top-tier Ampere predecessor, this version of the Lovelace powerhouse is an AIO-cooled GPU, connected to a massive 360mm aluminium radiator, that in turn has its temperature kept by three 120mm double ball bearing fans. In addition, the tubes that connect it to the CPU pump are made from FEP, designed to minimise the loss of water, as well as retain a high water pressure tolerance. The PCB itself comes with an aerospace-grade PCB coating and even has a 24+4 power phase design. Moving down the line to the non-AIO-cooled cards, Gigabyte’s AORUS lineup also has an air-cooled offering of the RTX 4090 in the form of the Master 24G. The card itself sports a revamped look and features what the brand says are new fan blades and an all-new surface design. Those fans, by the way, utilise their own WINDFORCE technology and have an increased static pressure of up to 30% over the last generation, while reducing their noise level by up to 3dB and running at the same RPM. Further, there’s a larger heatsink module with angular fins and the usual vapour chambers and heat pipes to draw the heat away from the GPU and exhausted out of the card. Oh, and the card has a small LCD called Edge View at the corner of the card’s spine that feeds information about the card’s status. Outside of Gigabyte’s AORUS line, the RTX 4090 can also be found in the brand’s non-descript Gaming OC SKU. In comparison, this card features a more minimalist aesthetics, with its front cooler shroud barely covering the massive heatsink beneath it. Of course, you still get the triple-fan WINDFORCE configuration and yes, it does have RGB built into it. Last but not least on Gigabyte’s RTX 4090 list is the WINDFORCE edition of the card. Like the Gaming OC, this card shows off a basic-looking design, but unlike the Gaming OC, it does away with any RGB LEDs, making it the perfect card for individuals that prefer a stealth or inconspicuous build. Regardless of Gigabyte’s four RTX 4090 SKUs, the specs for all cards remain largely the same. They’re still based off the same Ada Lovelace architecture that is made around the new 4nm process. Other details of the GPU include 24GB GDDR6X graphics memory running at 21Gbps, 4th generation Tensor Cores, 3rd generation RT cores, and a 384-bit memory bus. Also, all variants of the card are powered by a new 16-pin PCIe Gen5 power connector. At the time of writing, Gigabyte did not provide local pricing or availability for either card.
