七彩虹iGame RTX 4080 SUPER Neptune OC水冷显卡评测:470W性能远超所有!没谁比它更凉快
1. Foreword: Colorful brings the top water-cooled RTX 4080 SUPER graphics card The specifications and materials are non-public models
RTX 4080 SUPER has been listed, I believe everyone has a certain understanding of this graphics card, "increase the amount and reduce the price", starting from 8099 yuan, which is very worthy of consideration by high-end players.
However, almost all non-public cards only have about 2% performance improvement compared to RTX 4080, and even if you use three fans, the temperature will reach 66~68°C, which is obviously not ideal.
IS THERE AN RTX 4080 SUPER THAT CAN MAXIMIZE THE PERFORMANCE OF THE AD103 FULL-BLOODED GPU CORE, AND IT'S COOL ENOUGH?
There really is!
It is the iGame GeForce RTX 4080 Neptune OC 16GB from the Rainbow Water God family, which combines water cooling and graphics cards, both in terms of materials and specifications, it can be called a model of non-public graphics cards.
RTX 4080 SUPER uses a full-blooded version of AD103 cores in terms of specifications, with a total of 7 groups of GPC, 14 groups of TPC, and 80 groups of SM units, and a group of SM contains 128 CUDA cores, with a total of 10240 stream processors, which is only 5% different from RTX 4080.
There are also 320 Gen 4 Tensor Cores, 80 Gen 3 RT Cores, 320 texture units, 112 ROP units, and 64MB of L2 cache.
The video memory is also 256 bit wide, but the memory bandwidth specification has been slightly increased, which is 23Gbps memory frequency and 736GB/s video memory bandwidth.
Colorful iGame RTX 4080 SUPER Neptune OC graphics card has a built-in dual BIOS, the default BIOS is exactly the same as the public version, both are the maximum 2550MHz Boost frequency, but the TGP is unlocked to 350W, which is 30W higher than the public standard.
The overclocking BIOS has increased the Boost frequency to 2640MHz, and the TGP has reached an unprecedented 470W, which is a full 150W higher than the public version, which is comparable to the RTX 4090!
Combined with the extreme temperature control brought by the Colorful iGame RTX 4080 SUPER Neptune OC graphics card with liquid cooling, it is foreseeable that the potential will be more abundant than air cooling in terms of performance and overclocking.
Next, let's take a look at the performance of this colorful iGame RTX 4080 SUPER Neptune OC graphics card (hereinafter referred to as the iGame RTX 4080 SUPER Neptune OC graphics card).
2. Appearance: 360mm integrated water cooling and heat dissipation, 20+3 power supply design stacking is luxurious enough
The iGame RTX 4080 SUPER water god graphics card body looks very petite in front of the 360mm water cooler.
The silver and white graphics card body and the all-white water radiator look very sci-fi when matched.
The iGame RTX 4080 SUPER graphics card body uses an integrated alloy heat dissipation armor, as well as a double curve running through the card body, and the silver and white color scheme highlights the texture of this graphics card.
The size of the graphics card body is 253.5×170.8×41.5mm (with bezels), and it is only 2 slots thick, which is relatively slim among many RTX 4080 SUPER graphics cards.
With iGame Center, you can switch the lighting mode, and you can also synchronize the lighting with the motherboard, presenting your own light and shadow feast for players.
The Ice Sea Radiator uses a 360 radiator and is a 120mm fan with three 120mm fans, which can synchronize the lighting effects with the graphics card itself.
The size is 394×119.2×54.4mm, and the length of the water pipe is 420mm.
The lighting effect is very cool when you get on the plane.
The alloy outer armor backplate is more textured, and the metal bracket of the backplate is the average pressure of the GPU and PCB.
The movable rotating water block details support various installation methods, and the light synchronization line is wrapped with snakeskin net and water pipe, which avoids the user's trouble of managing the cable during installation.
The power supply interface uses 12VHPWR composed of 12+4 pins and a total of 16 pins.
Next to it is the RGB lighting interface, which can be connected to the 5V RGB and USB pins of the motherboard with the distributed data cable, and the graphics card can be synchronized with the whole machine.
3 DP1.4a and 1 HDMI 2.1a video outputs, up to 4K 240Hz or 8K 60Hz HDR with DSC support, up to 4 screens.
Next to the video interface is a button to switch between the silent BIOS and the OC BIOS.
After removing the metal backplate, you can see the full coverage of the copper bottom of the waterway, which can cover the key heating areas such as GPU cores, video memory, and power supply modules, and cooperate with the high-performance water pump to remove heat through the water cooling radiator, bringing excellent temperature control ability.
The front and back of the iGame RTX 4080 SUPER graphics card are detailed on both sides of the PCB.
The AD103-400 GPU core, using NVIDIA's custom TSMC 4N manufacturing process, has a chip area of 379 square millimeters and 45.9 billion transistors.
The video memory surrounds the GPU core, a single 2GB, a total of 8 to form a capacity of 16GB, the video memory frequency is 23Gbps, and the bandwidth is 736GB/s.
The power supply capacitance details of the iGame RTX 4080 SUPER graphics card are powered by 20-phase GPU power + 3-phase video memory, which is nearly double that of the RTX 4080 SUPER public version design.
IT'S NOT AN EXAGGERATION TO SAY THAT IT'S THE MOST LUXURIOUS GRAPHICS CARD IN THE RTX 4080 SUPER, AND THERE PROBABLY ISN'T ONE.

Under 4K high image quality + single ray tracing, although some games can run smoothly, they can't break 100 frames and can't give full play to the strength of the iGame RTX 4080 SUPER Water God, but after turning on DLSS 3 frame generation technology, it can achieve a minimum performance of 110 frames.
6. Stable Diffusion experience: TensorRT acceleration efficiency is as high as 9.58it/s, and it only takes 7 seconds to generate 1 image
Stable Diffusion is an image-based AI model that can generate a desired image by simply entering a sentence or a specific keyword, and is also the most popular AI-generated drawing tool at the moment.
NVIDIA has also introduced a TensorRT acceleration plug-in for the Stable Diffusion Web UI, which doubles the performance of GeForce graphics cards with Tensor units.
In this article, we will compare the performance differences between the SDXL acceleration method and PyTorch xFormers (the regular acceleration method).
The test conditions were based on space war, the sampling method was Euler a, the resolution was 1024×1024, and the iteration steps were 50.
With the default booster, the iGame RTX 4080 SUPER graphics card has a maximum generation speed of 2.46it/s, and it takes a total of 3 minutes and 45 seconds for 10 images, which is an average of 22.5 seconds per image.
After enabling NVIDIA's accelerator optimized for SDXL, with the blessing of TensorRT, the image generation speed of the iGame RTX 4080 SUPER graphics card directly came to 9.58it/s, and 10 images were generated in only 70 seconds, which is an average of 7 seconds per image, which is very impressive, which is 3.9 times that of the default accelerator.
7. Oven and overclocking: 10°C lower than air-cooled Overclocking brings a 6.23% performance improvement
- Oven
Bake under an overclocked BIOS, set the parameters of FurMark to 4K resolution + turn off anti-aliasing.
After 10 minutes of baking, the iGame RTX 4080 SUPER graphics card's GPU frequency stabilized at 2115MHz, power consumption stabilized at 350W, temperature was 58.6°C, and fan speed averaged 1540 RPM.
This is about 10°C cooler than the air-cooled RTX 4080 SUPER graphics card!
After 10 minutes, the GPU frequency of the iGame RTX 4080 SUPER graphics card stabilized at 1935MHz, the power consumption stabilized at 320W, the temperature was 57.1°C, and the fan speed was at 1465 RPM on average.
Compared to overclocking the BIOS, the temperature and fan speed pressure are also lower.
- Overclocking ovens
In this round of overclocking test, we increased the GPU frequency of the iGame RTX 4080 SUPER graphics card by 200MHz to 2495MHz-2840MHz, the equivalent frequency of video memory to 25.5Gbps, and the memory bandwidth to 816GB/s based on the overclocking BIOS.
Time Spy Extreme was re-tested, and after overclocking, it came to 15584, which is about 6.23% higher than the score of 14670 under the silent frequency.
After 10 minutes of baking, the GPU frequency of the iGame RTX 4080 SUPER water god graphics card stabilized at around 2655MHz, the power consumption increased to 470W, the temperature was still only 68°C, and the fan speed also came to 1930 RPM.
8. Summary: The top water-cooled non-public graphics card with extreme heat dissipation and performance
Colorful iGame GeForce RTX 4080 SUPER Neptune OC Water God Edition is a newly designed water-cooled graphics card, focusing on extreme performance and extreme temperature control.
Compared to comparable air-cooled graphics cards, the daily gaming temperature is a full 10°C lower, and even in overclocked BIOS mode, the temperature is controlled at 56°C at all times, and the fan speed is only 1250 RPM, which makes the sound almost inaudible.
Even when baking, the maximum temperature is only 58.6°C, and the fan speed is slightly provided at 1540 RPM, which can easily suppress the power consumption of 350W.
After overclocking, the power consumption of the oven reached 470W, but it was still able to control the temperature at 68°C, which is comparable to the silent frequency performance of the air-cooled RTX 4080 SUPER.
Compared with RTX 4080, whether it is 4K high-quality game performance or theoretical performance, the iGame RTX 4080 SUPER water god graphics card has increased by 4%, which is only a 2% increase compared to conventional air cooling, which is quite eye-catching, and fully exerts the performance of AD103 full-blooded GPU core.
Of course, it relies on a 360 radiator to exhaust heat, so the requirements for the chassis are also relatively high, and gamers need to pay attention to setting up the heat dissipation and air ducts of the chassis.
The price of Colorful iGame GeForce RTX 4080 SUPER Neptune OC 16GB has reached 9599 yuan, which may dissuade some players, but as a top non-public with performance, heat dissipation and temperature control to the extreme, it is completely worthy of this price, and it is also very suitable for top players with the ultimate pursuit.
