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

Nvidia’s GA102 graphics processing unit powering the GeForce RTX 4090 is designed to reach extremely high clock speeds well over 3 GHz. Apparently, according to a well-known hardware leaker, Colorful wants to make use of it in their new limited edition iGame GeForce RTX 4090 Kudan graphics card. @wxnod.

Colorful is reportedly working on a GeForce RTX 4090 Kudan graphics card which will feature an unprecedented maximum GPU frequency of up to 3088 MHz out of the box. This is 448 MHz higher than the maximum clock speed officially supported by Asus. ROG Strix GeForce RTX 4090 OC Edition (opens in new tab), the fastest RTX 4090 ever. By default, the iGame GeForce RTX 4090 Kudan comes with clocks of 2235 MHz/2520 MHz base/boost, but when OC mode is enabled, the maximum boost clock is boosted to 3088 MHz.

To support such extreme frequencies, the iGame GeForce RTX 4090 Kudan graphics board features an enhanced voltage regulation module and a custom cooling system that uses a combination of liquid and air cooling to cool the GPU, memory, and VRM. It has a hybrid cooling system. Used in previous generations of his Kudan products.

Like Colorful’s Kudan series, the iGame GeForce RTX 4090 Kudan will be limited in quantity and very hard to come by. Meanwhile, the 3GHz GPU clock makes it not only one of the best graphics cards, but arguably the fastest graphics board in the world. In fact, Colorful is purportedly considering using his GDDR6X memory at 23 GT/s on a dedicated board, which will further boost performance.

Even for Nvidia’s AD102, the out-of-the-box 3GHz GPU frequency is high, don’t worry about extreme cooling systems. The power limit for this card isn’t clear either, but we’ve seen 2.9 GHz with manual overclocking on most RTX 4090 cards we’ve reviewed, with power consumption often in the 500W range. Higher voltages may require dual 16-pin power connectors.

Of course, this information comes from an unofficial source, so please take it with a pinch of salt. We know that with liquid nitrogen he can reach 3.70 GHz while the AD102 GPU consumes about 1000W. It’s certainly plausible that it could exceed 3 GHz with conventional cooling, but I’m very curious about the actual clocks. If 3088 MHz is your boost clock, most Nvidia cards can actually exceed that value by 100-200 MHz. Kudan may struggle just to hit the boost clock, but surpassing it doesn’t matter.
