Colourful Preps GeForce RTX 4090 Kudan With 3GHz Clocks: Leak

Posted on

Nvidia’s GA102 graphics processing unit that powers GeForce RTX 4090 was designed to hit extraordinarily excessive clock speeds of nicely over 3 GHz. Apparently, Colourful needs to benefit from that with its new restricted version iGame GeForce RTX 4090 Kudan graphics card, in response to famend {hardware} leaker @wxnod.

Colourful is reportedly engaged on a GeForce RTX 4090 Kudan graphics card with an unprecedented most GPU frequency of as much as 3088 MHz out-of-box, which is 448 MHz greater than the utmost clock pace formally supported by Asus’s ROG Strix GeForce RTX 4090 OC Version (opens in new tab), the quickest RTX 4090 up to now. By default, the iGame GeForce RTX 4090 Kudan will include clocks of 2235 MHz/2520 MHz base/increase, however as soon as its OC mode is activated, its most increase clock can be amplified to 3088 MHz.

To help such an excessive frequency, the iGame GeForce RTX 4090 Kudan graphics board will characteristic an enhanced voltage regulating module and a customized hybrid cooling system that cools down GPU, reminiscence, and VRM utilizing a mix of liquid and air cooling, an analogous system is utilized by the previous-generation Kudan product.

Because it all the time the case with the Kudan sequence by Colourful, the iGame GeForce RTX 4090 Kudan can be out there in restricted portions and can be extraordinarily arduous to get. In the meantime, with a 3GHz GPU clock, it won’t solely be one of many greatest graphics playing cards, however will arguably the quickest graphics board on the earth. In truth, Colourful is allegedly trying to make use of 23 GT/s GDDR6X reminiscence with its unique board, which can additional increase its efficiency.

A 3GHz GPU frequency out-of-box is excessive even for Nvidia’s AD102, by no means thoughts the intense cooling system. It is also not clear what the facility limits are on this card, however we have seen 2.9 GHz with guide overclocking on a lot of the RTX 4090 playing cards we have reviewed, with energy draw typically within the 500W vary. Twin 16-pin energy connectors may be required with greater voltages to keep up 3 GHz.

Naturally, this data comes from an unofficial supply so please sprinkle liberally with salt. We do know that the AD102 GPU can hit 3.70 GHz with liquid nitrogen whereas consuming round 1000W. It is definitely believable that it might break 3 GHz with typical cooling, however we’re very inquisitive about real-world clocks. If 3088 MHz is the increase clock, most Nvidia playing cards are literally in a position to exceed that worth by 100–200 MHz. We suspect the Kudan could battle simply to achieve the increase clock, by no means thoughts exceeding it.
