ROG STRIX RTX 4080 SUPER OC: Redefining luxury in all aspects
The ROG STRIX RTX 4080 SUPER OC sports a fresh new look inspired by the iconic aesthetics of the ROG STRIX family, infused with elements from the cyberpunk universe. Its shroud features a striking red-to-blue gradient, while the top left corner boasts the reflective, totemic ROG emblem, accentuated by the trio of neon-lit "Gamer's Eye" fans on the cooling assembly.
In terms of cooling configurations, the ROG STRIX RTX 4080 SUPER OC boasts a brand-new cooling module design. It is equipped with an encircling metal flow shroud, metal backplate, and a die-cast metal frame, significantly enhancing the graphics card's resistance to deformation. The 3.5-slot extensive cooling system provides more cooling space and additional heat fins. Internally, it employs a direct-touch even-heat plate and embedded heat pipes design, incorporating four 8mm and three 6mm heat pipes. Compared to conventional even-heat plate designs, this configuration allows the graphics card to reduce its temperature by an additional 5°C under a thermal load of 500W.
The graphics card is also equipped with three Axial-tech axial fans, with a diameter reaching 104mm, which can deliver a larger airflow and air pressure. Moreover, it features a reverse rotation design for the central fan, effectively reducing turbulence and enhancing the efficiency of heat dissipation airflow. The fans utilize dual ball bearings, offering a longer lifespan than traditional sleeve bearings. This fan supports 0dB technology, allowing it to stop completely when the GPU core temperature is low, thus reducing noise during low-load situations. At the tail of the card, there are also two PWM FanConnect II ports, enabling players to connect additional fans as needed to improve the overall cooling performance of the platform.
In terms of power supply, the ROG STRIX RTX 4080 SUPER OC employs a super-alloy digital power supply solution. For the GPU section, it utilizes the MP2888A control chip along with the MP86992 (70A) MOSFET. As for the memory section, it employs the UP9529QQKF combined with the SIC654A (50A) power supply scheme, ensuring ample and stable power delivery for high-frequency operation of the graphics card. Additionally, the ROG STRIX RTX 4080 SUPER OC also incorporates ASUS's fully automated manufacturing process, effectively eliminating human errors during production and thereby enhancing durability.
In terms of connectivity, the ROG STRIX RTX 4080 SUPER OC comes equipped with three DP 1.4 ports and two HDMI 2.1 ports, perfectly meeting the needs of gamers looking to set up multi-monitor systems or those desiring 8K resolution and high refresh rate displays without a hitch. As for specifications, the default boost clock of the ROG STRIX RTX 4080 SUPER OC is 2640MHz, with an OC mode pushing it to 2670MHz, which is significantly higher than the standard version's 2550MHz.
As many of you are aware, Stable Diffusion is currently the hottest local AI image generation tool on the market. The RTX 4080 SUPER, with its formidable computing power and 16GB of substantial VRAM, along with an unmatched CUDA ecosystem, makes it the most efficient and compatible choice for running this application. Let's dive into the actual AI imaging performance of the ROG STRIX RTX 4080 SUPER OC.
With its ample VRAM and robust computing power, the RTX 4080 SUPER delivers impressively sharp images.
Test Setup:
Generating 10 images with a resolution of 512×512 took only 47 seconds with the ROG STRIX RTX 4080 SUPER OC.
Let's run a cyberpunk girl using Stable Diffusion, with the Maigo's beautiful model, DPM++ 2K Karras sampling method, 512×512 resolution, 50 iterations, prompt guidance coefficient of 7, 1 image per batch for a total of 10 batches, with a fixed random seed of 14 for easy comparison testing. From the test results, out of 10 images generated, the ROG STRIX RTX 4080 SUPER OC only took 47 seconds, showcasing remarkable efficiency.
Feeling the 512×512 resolution isn't cutting it? No worries, we can easily crank it up to 1024×1024, while still churning out 10 images. Sure, this amps up the demand on VRAM, but the RTX 4080 SUPER's beefy 16GB of VRAM doesn't even break a sweat, clocking in at just 99.5 seconds. That's a quadruple boost in pixel count, with only a slight nudge over double the time, showcasing the ROG STRIX RTX 4080 SUPER OC's powerhouse performance in rendering.
Using high-definition restoration, the previously generated 512×512 image has been elevated to 2048×2048, with the ROG STRIX RTX 4080 SUPER OC clocking in at just 44.8 seconds. We're well aware that one of the many strengths of the Tile model lies in its ability to polish up blurry images. By applying it to a previously generated 512×512 cyber-themed image, and boosting the resolution by four times to 2048×2048, the clarity and detail enhancement across the entire image is starkly evident. The task was accomplished in a mere 44.8 seconds with the ROG STRIX RTX 4080 SUPER OC, where the 16GB of substantial video memory played a pivotal role, making high-resolution AI computations a reality.
Just flaunting the ROG STRIX RTX 4080 SUPER OC's muscle might not quite convey its formidable AI imaging capabilities. So, we've benchmarked it against NVIDIA's official standards for a clearer comparison. The specific settings included Euler a sampling, 50 sampling steps, a CFG Scale of 7.5, 2 images per batch, and 10 batches total, culminating in a count of images produced per minute. The results? The ROG STRIX RTX 4080 SUPER OC churns out images at a speed approximately 105% that of the RTX 4080, marking a whopping 42% increase over the RTX 3080 Ti, and astonishingly, it's 181 times faster than the Core i9 13900K.
Additionally, the RTX series GPUs can further significantly enhance the rendering speed of Stable Diffusion by optimizing models through NVIDIA's TensorRT. We optimized the models of both Stable Diffusion XL and Stable Diffusion V1.5 using NVIDIA TensorRT to compare the changes in rendering efficiency of the ROG STRIX RTX 4080 SUPER OC before and after optimization. When using the Stable Diffusion V1.5 model, we selected rendering resolutions of 512×512 and 768×768 respectively, while for the Stable Diffusion XL model, we used a rendering resolution of 1024×1024 (the same as the training model's image resolution). Other parameters include Euler sampling, 50 sampling steps, CFG Scale of 7, batch size of 1, and 10 batches.From the test results, it can be seen that with TensorRT, the rendering speed of the ROG STRIX RTX 4080 SUPER OC increased by 101%, 142%, and 104% in the three environments respectively, all achieving more than double the increase. This indicates that the effect of TensorRT is indeed outstanding and worthy of use by Stable Diffusion players—of course, it also requires the support of AI powerhouse like the ROG STRIX RTX 4080 SUPER OC to unleash its full potential.
In summary, the RTX 4080 SUPER is not only a powerhouse for 4K gaming, but also a sharp tool for AI Graphics Computing.
From the previous tests, it can be seen that the ROG STRIX RTX 4080 SUPER OC, with its powerful computing power and 16GB of super-large memory, not only provides extremely efficient rendering in Stable Diffusion, but also boasts excellent adaptability for high-resolution rendering, truly surpassing mainstream graphics cards as a high-end AI rendering tool. Additionally, we also see that the ROG STRIX RTX 4080 SUPER OC is made with luxurious materials and exquisite craftsmanship, ensuring reliable stability during heavy rendering tasks. In conclusion, if you need a high-end equipment that can provide both a 4K high-frame gaming experience and powerful AI computing, then the ROG STRIX RTX 4080 SUPER OC is indeed a great choice.
