One of the world's largest supplier of graphics cards, Colorful is no stranger to offering exclusive products. This week the company quietly rolled out the world's only GeForce RTX 4070 with a closed-loop cooling system. The graphics board promises to provide the ultimate overclocking experience, but its price may be too high for many to justify it..
Colorful's iGame GeForce RTX 4070 Neptune OC-V relies on Nvidia's AD104-250 graphics processor with 5,888 CUDA cores mated with 12GB of GDDR6X memory using a 192-bit interface, but uses a proprietary printed circuit board with a 14+3-phase power delivery to maximize GPU overclocking potential. The board comes with a one-key overclocking function enabling up to 2640 MHz boost clock, up from 2,475 MHz by default. The board uses a 12+4-pin 12VHPWR auxiliary PCIe 5.0 power connector and is rated for a TDP of up to 230W, which is 30W higher than that of Nvidia's reference design.
