As the launch date for Nvidia’s GeForce RTX 4080 approaches, the add-in board maker has revealed some interesting details, revealing the specifications of the device. For example, this week Colorful revealed the final specs for its iGame GeForce RTX 4080 16GB Neptune OC graphics card. It comes with a high-end closed-loop cooling system and a total graphics power cap of “just” 380W.
colorfulz iGame GeForce RTX 4080 16GB Neptune OC The is powered by Nvidia’s AD103 graphics processor with 9728 CUDA cores paired with 16 GB of 22.4 GT/s GDDR6X using a 256-bit interface. With the out-of-the-box single-click overclocking feature applied, the GPU can boost up to 2640 MHz. That’s about 5% faster than his 2520 MHz for Nvidia’s recommended boost clock. However, add-in board makers have yet to enable truly high clocks for their out-of-the-box Ada Lovelace architecture cards. Either way, the AD103 AIB may join the ranks of the best graphics cards for gaming this year.
Colorful equips its GeForce RTX 4080 Neptune OC graphics card with a 22 + 4 phase voltage regulation module (VRM). This could be more advanced than the 18+3 phase power circuit Nvidia uses for his GeForce RTX 3090 and GeForce RTX 3090 Ti. The Founders Edition boards are rated at 350W and 450W respectively. With such a VRM, Colorful promises greater overclocking potential for his GeForce RTX 4080 Neptune.
To ensure proper cooling for their top-of-the-line AD103-based product, the manufacturer equips the iGame GeForce RTX 4080 Neptune OC card with a closed-loop cooling system that can also be used to top the current range. iGame GeForce RTX 4090 Neptune An OC card with 630W of thermal graphics power said: video cardsBut there is interesting information about the TGP of the iGame GeForce RTX 4080 16GB Neptune OC.
The RTX 4080 Neptune OC’s TGP is capped at 380W. That’s about 19% more than Nvidia’s recommended 320W. 380W is still a very high TGP (higher than AMD’s Radeon RX 7900 XTX), but it’s worth noting that Colorful modestly limits his AD103-based offering. Perhaps the AD103 overclocks very well without a significant increase in power consumption, or maybe Colorful just wants to play relatively safe with this graphics chip.
Colorful could start selling the iGame GeForce RTX 4080 16GB Neptune OC on November 16th. This is about the time other of his AD103 powered boards hit the market. Pricing for the board is unknown, but don’t expect to buy it at Nvidia’s suggested retail price of $1199, as it’s factory overclocked with advanced his VRM and a very good cooling system.
