ROG Strix GeForce RTX 4080 OC unboxing
ASUS here. On the first-generation ROG Strix graphics card, the heat sink has been completely redesigned to meet the higher heat dissipation requirements of the RTX 40 series. In addition to increasing the size to 3.5 slots thick and 35 cm long, the contact part between the heat sink and the core has also been replaced with a uniform Warm heat conduction plate so as to achieve better heat dissipation efficiency.
This time, the core part of NVIDIA RTX 4080 has 76 SM units and 9728 CUDA cores, including 304 fourth-generation Tensor cores and 76 third-generation RT cores. It also supports this new generation of DLSS 3 technology like RTX 4090, has 2 NVENC encoders and supports AV1 encoding.
In terms of performance, the core clock of ROG Strix RTX 4080 OC can be increased to 2655 MHz by turning on the overclocking mode in the GPU Tweak III software. This generation still has dual Bios functions, so whether players want the ultimate performance or a quiet experience, this graphics card can meet various user needs.
The 12VHPWR power adapter cable is provided in the accessory so the player can supply power for this graphics card without replacing the ATX 3.0 power supply. If the adapter cable looks messy after installation, you can use the devil in the accessories. Felt cord management straps secure. In addition, there is a dual-purpose metal graphics card support frame in the accessories. If you can’t find a screwdriver when installing the computer, reverse the support frame’s centre to become a small screwdriver.
3.5-slot jumbo, circular LED lighting effects without dead ends
In terms of appearance, the design of this generation also maintains a square shape, with a super-large ROG Logo on the front, and the fan part is replaced with a new generation of axial fans, which are larger in size than the previous generation, and Replaced with a 7-blade fan blade design, the airflow and air pressure have been improved, and the waste heat of the radiator can be removed faster.
It can be seen from the side that there is no long strip light strip of the previous generation in the design, and a larger opening is left to allow the wind to pass through more smoothly, while the side lighting effect design returns to the classic REPUBLIC OF GAMERS luminous Logo in the lower right corner.
At the end of the graphics card, a ring light is designed this time, with 360-degree coverage without dead ends, so that the light effect can be seen no matter how installed the graphics card. Still, if you want to achieve the best visual effect, you can match it with a glass panel in front of the TUF GT502, and you can look directly at the internal chassis to see the ring light, no matter the front or side.
The design of this generation of the metal back panel also has ventilation openings on the side, but unlike the common large-area openings, this time, the striped openings are used in the design, so you can see that it can not only achieve the effect of ventilation, but also It can make ROG Logo similar to Glitch effect on the opening, taking into account heat dissipation and visual effects at the same time.
After removing the 3.5-thick radiator, you will find the design very special. The middle frame is directly connected to the fan cover, and the middle is the heat dissipation fin. The fin part is penetrated by 4 heat pipes, and the heat dissipation fin On the top of the chip, you can see a large-area uniform temperature heat conduction plate, which can accelerate the waste heat dissipation of the core chip and memory.
In the centre of the PCB is the RTX 4090 core chip code-named AD102-300-A1, and on one side are 12 2GB Micron memory particles code-named D8BZF. The supply part uses an 18+4 phase digital power supply and Super Alloy Power II top aluminium alloy inductors. With a 15K capacitor.
GPU Tweak III Software
GPU Tweak III is ASUS’ graphics card monitoring and overclocking software. The software provides three different performance modes for players to quickly adjust the mode. Of course, manual overclocking is also possible. In terms of fan settings, ROG Strix RTX 4080 OC The fan is automatically turned on by default, and ASUS has optimized the fan tuning for RTX 40 series graphics cards in the software so that this generation of graphics cards can have the best cooling effect, that is, noise performance.

The DX12 API test is also conducted using 3DMark. The Time Spy series mainly tests the game performance under DX12. The default resolution is 2K. The ROG Strix GeForce RTX 4080 OC got a graphics card score of 29,148 points, while the 4K Extreme test got a graphics card score of Score 14,610 points.
Port Royal is a game simulation test with ray tracing technology. The default test resolution is 1440p. ROG Strix GeForce RTX 4080 OC passed the test and got a graphics card score of 18,428. The newly launched Speed Way test was also conducted at 1440p resolution, but It is developed by DirectX 12 Ultimate API, and many new technologies are applied in the design, and the graphics card score is 7,363 points in the test.
In addition, in the NVIDIA DLSS feature test project, a DLSS 3 test has been added. This test also includes DLSS 2 and DLSS 3. In the actual test, 1440p and 2160p are tested in performance mode, and 4320p is tested in ultra-high performance mode. DLSS 2 can provide about 2~3 times performance improvement, while DLSS 3 will improve the performance even more. The results are for players’ reference.
Game Performance Test
In the game test section, select “Dianyu Renren 2077”, “Watch Dogs: Freedom Legion”, “Far Cry 6”, “Forza Motorsport: Horizon 5”, “Assassin’s Creed: Viking Age”, “SUPER PEOPLE”, and “Rainbow Six: Evacuate the Restricted Zone” were tested. The test resolution was 1440p and 2160p for players’ reference. The newly added test “SUPER PEOPLE” is a battle royale multiplayer online shooting game that supports DLSS 3.
According to the actual measurement, it can be seen that when the AAA masterpiece is fully turned on at 2160p, although the average frame rate cannot be as high as that of the RTX 4090, it also falls at around 80~90 frames. The overall performance is not bad, and the competitive games are OK Break a hundred frames.
If the light-chasing game is a performance-hungry game like “Dian Yu Ren Ke 2077” and “Watch Dogs: Freedom Legion”, the 2160p is about 30 frames, and the 1440p is about 60 frames. Overall, it is not bad Accepted, but after DLSS is turned on, it can basically have about 100 frames. Therefore, for light-chasing games, with the support of powerful DLSS technology, it can also give a smooth game experience.
Creation software test
For the productivity test, Blender, a cross-platform 3D creation software, was chosen for the test. Under the test of Blender Benchmark 3.3, the number of samples per minute for the monster scene was 5002, that of the junkshop was 2287, and that of the classroom was 2409.

Through FurMark, Time Spy Stress Test, and GPU-Z, simulate the temperature under high load, DX12 games, and standby. And power consumption. The temperature of ROG Strix GeForce RTX 4080 OC on standby is 43 degrees, and the power consumption of the whole platform is 93 W; the temperature of the Time Spy Stress Test is 61 degrees, and the power consumption of the whole platform is 436 W; the temperature of FurMark 4xMSAA is 59 degrees, The power consumption of the whole platform is 369 W.
ROG Strix GeForce RTX 4080 OC Summary
ROG Strix RTX 4080 OC was launched by ASUS this time. Although it continues to use the radiator of the big brother RTX 4090 version, the overall size has not been reduced, but it has exceeded expectations in terms of heat dissipation. The machine test shows that the temperature is only around 60 degrees, which is an amazing performance.
The performance is partly because the current mainstream is still 2K monitors, so I believe that RTX 4080 may still have excess performance for most players, but if players want to change to 4K monitors or want to play AAA games under 2K, they can have a smooth performance of over 100 frames For the screen, you can still consider starting with RTX 4080.
Overall, if players want to buy the flagship RTX 4080, this time, ASUS ROG STRIX RTX 4080 OC has excellent performance in terms of performance, heat dissipation, and appearance. Interested players can refer to it.
