In the flagship-level non-public version of the GPU, the iGame Neptune series is a special existence, not only good-looking, but also with integrated water cooling and heat dissipation, and the combat effectiveness is quite capable. With the release of NVIDIA's flagship GeForce RTX 4080 SUPER at CES 2024, the most powerful model of iGame Neptune in SUPER was born, called iGame GeForce RTX 4080 Super Neptune OC 16GB.
In terms of parameters, GeForce RTX 4080 Super performance is quite good, using a complete AD103 core for the first time, tens of thousands of CUDA cores, 320 *** Tensor Cores provide 836 tops of AI computing power, and 80 third-generation RT cores with optimized structure provide a more efficient way to run ray tracing and path tracing games, with DLSS 35. Frame insertion and light reconstruction, the image quality and efficiency are further doubled. Combined with NVIDIA Studio optimization, ** modeling and other content creation is also quite capable of playing.
Yes, in the recently released RTX Super series, GeForce RTX 4080 Super is the existence of a computing power ceiling, and one of the tasks of iGame is to use a stronger cooling system and GPU tuning to make its performance go further. How does the iGame GeForce RTX 4080 Super Neptune OC 16GB perform? This is the first review.
Fully matched AD103
As mentioned at the beginning, the iGame RTX 4080 Super Neptune OC uses a fully equipped AD103 core, just from the naming convention of the AD103-400-A1, it is more powerful than the AD103-300-A1 of the RTX 4080, and retains all the functions of the AD102 in the function, using the ADA Lovelace architecture derived from TSMC's 4N custom process, with 45.9 billion transistors, The core area is 379mm.
In the ADA Lovelace architecture, the GPU contains several GPCs (Graphics Processing Clusters), GPCs contain several TPCs (Texture Processing Clusters), several Streaming Multiprocessors (SMs), and then CUDA and RT cores, tensor cores, and so on. The number of TPCs contained in each GPC is equal, and the GPC and TPC are physically shielded when the GPUs are positioned and differentiated.
The full AD103 contains 7 GPCs, but each GPC contains different TPCs. As shown in the figure below, while each of the 6 GPCs has 6 TPCs, there is also 1 GPC with only 4 TPCs. For example, at the time of the RTX 40 series release, the GeForce RTX 4080 was implemented by shielding 1 set of TPCs.
The iGame RTX 4080 Super Neptune OC doesn't compromise on the configuration with a full core count, i.e. the full AD103 with 10,240 CUDA Cores, 80 RT Cores, 320 Tensor Cores, 320 texture units, and 112 ROPS. On the memory subsystem, there is a total of 10MB of L1 cache, 20MB of register heap, and 64MB of L2 cache.
In particular, the 64MB L2 cache is a 12% increase over the 5MB of the GeForce RTX 30808x, which makes this in the game a huge benefit from ray tracing, especially path tracing. The third-generation RT Core and **Tensor Core can better play the effect of L2 cache.
Not only that, but the frequency of the iGame RTX 4080 Super Neptune OC has also been further upgraded, from the public version of the 2550MHz boost frequency to 2640MHz after one-click overclocking, which gets an additional 90MHz performance bonus. With a 256-bit 16GB GDDR6X, the memory bandwidth reaches 736GBS.
The base power consumption of the iGame RTX 4080 Super Neptune OC is the same as that of the RTX 4080, which is also 320W, and in order to provide more possibilities for later overclocking, the iGame RTX 4080 Super Neptune OC increases the maximum power consumption to 470W. Even so, the performance of this GPU is still very high, and in the gaming power test, the timing power consumption of the 4K resolution GPU with the highest image quality is roughly within 250W.
In addition, compared to the 3 8th Gen NVENC and 3 5th Gen NVDEC configurations of professional graphics cards, the iGame RTX 4080 Super Neptune OC encoder is configured with 2 8th Gen NVENC and 1 5th Gen NVDEC, which is a regular operation of consumer-grade GPUs and has little impact on game performance and AI acceleration performance.
The ultimate evolution of the water god
Compared to the iGame RTX 4070 Super Neptune OC, the iGame RTX 4080 Super Neptune OC's water-cooled combat power has been taken a step further. It is still a dual-card slot design, with only the iGame logo and two RGB decorative light strips in front of the graphics card, as well as Neptune on the back to show the identity.
This combination looks great in a white-themed case, especially when the RGB is lit up, and the quiet operation of the graphics card itself fits well with Neptune's deep-sea theme.
The iGame RTX 4080 Super Neptune OC uses an efficient all-in-one water pump chamber design, which covers the GPU, video memory, and power supply with a whole copper plate, and uses the metal bracket on the back plate as a force support to improve the durability of the graphics card. At the same time, the capacitors on the back of the GPU core are hollowed out, vaguely hinting at the performance strength of the RTX 4080 Super.
The point is that the iGame RTX 4080 Super Neptune OC is connected to a 360 radiator, and you must know that the previous generation RTX 3090 Neptune is only a 240 radiator. The 360's triple radiator fan is equipped with a very natural RGB effect, and the left side of the 12vhpwr power connector is equipped with an ARGB light synchronization and USB pin synchronization cable, which is convenient for modding more customized lighting effects.
The connection between the iGame RTX 4080 Super Neptune OC and the radiator uses a set of rotatable design, with a steering range of slightly less than 180°, and with a long enough water cooling duct, it can already meet the needs of the graphics card water cooling fan up or down. Of course, when purchasing a case, you should also remember to prepare enough space for the 360 radiator.
The effect of the radiator is quite intuitive, and under the stress test, you can see that the high temperature can be completely cooled except for the PCB cutout on the back of the graphics card.
In the Furmark stress test, the advantages of all-in-one water cooling can be seen more directly. Because water has a higher thermal conductivity and specific heat capacity than air, water-cooled systems are often more likely to achieve more efficient heat dissipation than air-cooled systems, while also rising more slowly under load than air-cooled systems. The iGame RTX 4080 Super Neptune OC core temperature ramp up is a slow process.
Finally, in terms of interfaces, the iGame RTX 4080 Super Neptune OC maintains 3 DisplayPort 1 in addition to the one-button overclocking mechanical buttons on the panel4A port and 1 HDMI 21a interface.
Combat power soars
With the blessing of 360 cold radiator, the combat effectiveness should not be underestimated. Now let's jump right into the test. In the test, the combination of iGame Ultra Family Bucket and Core i9-14900K was used, including iGame Z790D5 Ultra motherboard, iGame DDR5 16GB 6800*2 Ultra W memory, CN700 2TB Pro SSD, iGame C23A Ultra W case, iGame P850G Ultra W power supply, and iGame LQ360 Ultra W liquid cooling, iGame F12025 Ultra W fan. The specific configuration is as follows:
Among them, in the 3DMark Time Spy, 3DMark Time Spy Extreme, 3DMark Fire Strike Extreme, 3DMark Fire Strike Ultra, Port Royal section that detects the performance of DirectX 11 and DirectX 12, you can see that the iGame RTX 4080 Super Neptune OC performs quite quickly, which is faster than RTX The 4070 Ti Super is about 20 percent better, and 60 to 70 percent higher than the previous-generation RTX 3080.
Therefore, if you use DLSS 2 and previous regular games, the iGame RTX 4080 Super Neptune OC can achieve a 45% to 80% improvement over the RTX 3080 Ti at the highest 4K quality.
The iGame RTX 4080 Super Neptune OC vs. GeForce RTX 2080 Super will increase by between 150% and 250%.
DLSS 3 and DLSS 3 brought to the GeForce RTX 40 Series5 technology is the most important, due to the huge performance improvement of Tensor Core, supplemented by the combination of optical flow accelerator (OFA) and DLSS, a more three-dimensional analysis method is built, so that the actual execution process of the GPU is compressed to the original 1 8.
dlss 3.5 is a set of AI-based algorithms to improve image quality and frame rate at the same time, including DLSS frame generation (FG) and ray reconstruction (RR) technology, plus super resolution (Super Resolution), DLAA, frame generation (Frame generation) and other technologies integration.
If you use the RTX 3090 as a comparison, you will find that even with the blessing of 24GB video memory, the RTX 3090 is weaker than the iGame RTX 4080 Super Neptune OC in terms of picture smoothness, regardless of 4K or 8K resolution.
In terms of game image quality improvement, if you use DLSS 35 of Cyberpunk 2077 for comparison, you can see in DLSS 35 Rays are reconstructed to achieve a more natural effect, with the emphasis on achieving higher frame rates.
Also in DLSS 3 and later versions, the iGame RTX 4080 Super Neptune OC performs very strongly. Here we directly turn on the 4K highest image quality, turn on ray tracing or path tracing. It can be seen that the iGame RTX 4080 Super Neptune OC can be improved by up to 60% to more than 200% compared to the RTX 3080 Ti, and compared with the RTX 2080 Super, the maximum is more than 800%, of course, because the GPU cannot push it, and in terms of general results, the iGame RTX 4080 Super Neptune OC is 300% higher than the RTX 2080 Super Up and down is not a problem.
The higher performance, as well as the integration of DLSS 3 and Reflex, also makes the iGame RTX 4080 Super Neptune OC even more impressive in competitive games. Especially at 1080p, games like Valorant and Counter-Strike 2 achieved very high frame rates, and relied on Reflex to reduce system latency to less than 10ms, which is very exaggerated.
AI has been greatly improved
Another impressive upgrade to the iGame RTX 4080 Super Neptune OC is the AI performance experience brought by the 16GB GDDR6X. Here we might as well take Stable Diffusion XL as a reference, Stable Diffusion XL itself needs to rely on Transformer transformers and convolutional neural networks to operate, both of which require GPUs for massively parallel computing, which is undoubtedly what NVIDIA does best. Because of this, the rapid development of AI in recent years has been largely driven by the development of NVIDIA GPU technology.
Not only that, but Stable Diffusion XL is quite stable Diffusion 1 in terms of model size5 is 3 times larger, resulting in a higher amount of data to be calculated, but also better image quality.
As a rule, here we use Stable Diffusion Web UI + TensorRT to describe and generate 10 interstellar voyages with a resolution of 768x768 in shorter language**, with 1 image per operation**, that is, a total of 10 executions, and the number of sampling steps is set to 50.
Descriptions use: Epic Space Battle Over a Water Planet, Many Ships, Cinematic Lighting, Depth of Field, Hyper-Detailed, Beautifully Color-Coded, 8K, Many Details, Chiaroscuro Lighting
By recording the time, the estimation efficiency per minute is calculated, and the reference formula is 60 (totaltime (batchsize * batchcount)) = images per minute.
The iGame RTX 4080 Super Neptune OC easily outperforms many GPUs in recent reviews, with a performance improvement of more than 26% even compared to the RTX 4070 Ti Super with the same video memory.
In the ** resolution increase with ON1 Resize AI 2022, it can be seen that the iGame RTX 4080 Super Neptune OC completed the ** resolution increase in the shortest time, which is half the time compared to the RTX 3080.
In the first to use DLSS 35. The situation is very similar in the D5 renderer, a domestic software that does AI acceleration. dlss 3.5 It is trained with 5 times more data than DLSS 3, so it can also better identify ray tracing effects and make more reasonable judgments in temporal and spatial data, so as to achieve efficient scaling.
With the support of the iGame RTX 4080 Super Neptune OC, the software smoothness has undergone a qualitative change, easily reaching more than 60FPS, which is also 36% higher than that of the RTX 4070 Ti Super.
At the same time, the image quality of scenes rendered in real time has also undergone a qualitative change, such as in DLSS 35 When closed, the reflection on the ground becomes very rough, the glass on the left side loses its refraction and transparency, and the frame rate is reduced to less than half of the original.
Creation is invincible
Finally, thanks to NVIDIA's influence in various industries, professional applications built around CUDA Core and RT Core have actually affected the experience of using professional software in various industries. A good example of this is SpecViewPerf, a 3D graphics performance test for systems running under OpenGL and Direct X APIs, including 3DSMAX, Catia, Creo, Energy, Maya, Medical, SNX, and SolidWorks.
The iGame RTX 4080 Super Neptune OC is capable of delivering a 50% to nearly 90% increase in frame rates compared to the RTX 3080 in professional applications.
With more CUDA Cores, the iGame RTX 4080 Super Neptune OC has a strong performance in both CUDA performance and ray tracing, which is 60% better than the RTX 3080.
Octane Render RTX is used to test the ray tracing performance of the GPU, testing the sample rate generated by the GPU in complex scenes, and the iGame RTX 4080 Super Neptune OC nearly doubles the performance compared to the RTX 3080.
Finally, in the three reference scenarios introduced by the Blender Benchmark, Moser, Junkshop, and Classroom, the iGame RTX 4080 Super Neptune OC is 60% higher than the RTX 3080, and the highest is more than 80%.
Write at the end: super new flagship
The iGame GeForce RTX 4080 Super Neptune OC 16GB impresses a lot, with 360 all-in-one liquid cooling, a white exterior, and a gorgeous and naturally transitioning RGB effect.
The RTX 4080 Super really shows too many amazing combat power under the appearance of high scores, faster generative AI acceleration, DLSS 3 plus Reflex to achieve high frame rates and low system latency in competitive games, providing more possibilities for competitive win rates in games. And then there's DLSS 35's path tracing, ray reconstruction, and frame generation upgrade the game quality and smoothness that was not felt on previous GPUs in the GeForce RTX 40 Series.
With the blessing of all-in-one liquid cooling, the iGame GeForce RTX 4080 Super Neptune OC 16GB has been well tuned for temperature and performance release, and it releases more performance than the public GPU, and the split structure also provides more possibilities for the chassis layout. Especially for students who have high requirements for the neatness of the inside of the case, the iGame GeForce RTX 4080 Super Neptune OC 16GB provides a split layout, high-performance release, and good looks, which are difficult for most competitors on sale to achieve.
And if you are still using a mid-to-high-end GPU such as the RTX 3080, you can not hesitate now, for a long time to come, the 14th Gen Core with the GeForce RTX 40 series is the ideal choice, especially like the iGame GeForce RTX 4080 Super Neptune OC 16GB full of personality and performance of the new Super flagship, the next year of PC use experience, will definitely be quite happy.
