ROG Strix RTX 4090 OC Out of the box
The ROG Strix The RTX 40 series graphics cards have been replaced with a new design. Of course, on the first launch of the ROG Strix RTX 4090 OC, you can see that the overall size is larger this time, with a length of nearly 36 cm and a thickness of 3.5 slots. , and has a weight of about 2.5 kg. Among the RTX 4090s this time, it can be regarded as a heavyweight style.
In addition to the cooling upgrade this time, a new generation of Ada Lovelace architecture is used in the core part, with 128 sets of SM units, including 512 fourth-generation Tensor cores and 176 third-generation RT cores, and can support new ones. The factory default of the core Boost clock is overclocking to 2610 MHz. Turn on the overclocking mode in the GPU Tweak III software, and you can further increase the Boost clock to 2640 MHz.
First of all, let’s see the accessories part. This time, the new RTX 4090 adopts the 16-Pin 12VHPWR power supply interface, so the accessories also have 16-Pin to 4 8-Pin power adapter cables, so that players can upgrade ATX 3.0 without upgrading. The standard power supply can also power the RTX 4090 graphics card.
Considering that most players should use 16-Pin to 4 8-Pin power adapter cables, the ROG believes devil felt cable management belt in the accessories can play a role in the entire line. In addition, due to the long design The design of the strip, so can show different patterns when used in different directions.
In addition, there is also the same dual-purpose graphics card support frame in the TUF Gaming accessories. Since the RTX 4090 series graphics cards are more than 3 card slots thick this time, this metal support frame is relatively short in size, but in addition to the function of the graphics card support frame, After the middle bracket is removed and installed in reverse, it can be turned into a simple small screwdriver.
The 3.5 slots, forward and reverse axial fans, 7 heat pipes
The front design is not as technological as the previous generation. However, under the new design, you can see the oversized ROG Logo on the front, which can be said to be quite domineering visually. In the fan part, a 7-blade axial fan is used this time, and the forward and reverse directions are staggered to maximize the wind flow.
In order to meet the heat dissipation requirements on the side part, there is no light Bar on the side, only the luminous RGB Logo is left. In the front part of the side, you can see the switch of dual Bios mode, and the direction signs of “P mode” and “Q mode” can be seen on the metal back panel. Good performance, and “Q mode” mode will be quieter.
When you look at the back of the graphics card, you can also see the words ROG and the ROG Logo. What’s more special is that the tail area and the oblique clause are used to open the hole, so that the Logo has the visual effect of a Glitch, and it can also make this area at the same time. The airflow can directly pass through the backplane to achieve more efficient heat dissipation.
At the end of the graphics card, you can see that there is a unique ring light covering this time, and the middle is a horizontal strip-shaped metal frame. What is more special is that this time, the position of the two 4-Pin PWM fan connectors has been changed to this side, which is more convenient. Players can use the whole line better.
On the other side, you can see the familiar 304 stainless steel 2-slot baffle, and the display output is given to 2 HDMI 2.1 and 3 DisplayPort 1.4a, which can output up to 4 images at the same time.
In the heat dissipation part, after disassembling the heatsink, you can see the part where the heatsink is in contact with the core. This time, a new uniform temperature heat guide plate is used to effectively discharge the waste heat from the core, that is, the memory area. The chip is equipped with 7 heat pipes that run through the entire set of radiators so that the waste heat can spread to the entire fins more quickly, and then the waste heat is taken away by the fan.
In the centre of the PCB, you can see the RTX 4090 core chip codenamed AD102-300-A1, and on the side are 12 2GB Micron memory chips codenamed D8BZC. The power supply part uses a 24+4-phase digital power supply, Super Alloy Power II top aluminium Alloy inductor with a 15K capacitor.
GPU Tweak III Software
GPU Tweak III is ASUS’ graphics card monitoring and overclocking software. There are three different performance modes in the software for players to quickly adjust the mode. Of course, manual overclocking is also possible. On the fan setting, ROG Strix RTX 4090 OC The fan is automatically stopped by default, and ASUS has optimized fan tuning for RTX 40 series graphics cards in the software so that this generation of graphics cards can have the best cooling effect and noise performance.
Basic Performance Test

ROG Strix GeForce RTX 4090 OC In GPU-Z, you can see that the core part adopts AD102 core chip of Ada Lovelace architecture, the process is 4 nm and has 16384 Cuda cores, and the memory is Micron GDDR6X 384-Bit 24576 MB ( 24GB), the core clock is 2265 MHz, the Boost clock is 2610 MHz, and the memory clock is 1313 MHz (21Gps). In this test, the overclocking mode is turned on in GPU Tweak III, so the actual Boost clock during the test is 2640 MHz.
3DMark is a performance test software that simulates 3A-level game graphics operations. The Fire Strike series simulates the running of DX11 games. In the Fire Strike test with FHD resolution, ROG Strix GeForce RTX 4090 OC scored 83,368 points; 2K The graphics card scored a score of 47,768 in the Fire Strike Extreme test at 4K resolution and 25,904 in the Fire Strike Ultra test at 4K resolution.
The DX12 API test is also performed using 3DMark, while the Time Spy series mainly tests the game performance under DX12. The default resolution is 2K. The ROG Strix GeForce RTX 4090 OC scored 37,777 points for the graphics card, while the Extreme test with 4K image quality obtained the graphics card. Score 20,048 points.
In the ray tracing part, Port Royal is a game simulation test that adds ray tracing technology. The default test resolution is 1440p. ROG Strix GeForce RTX 4090 OC passed the test and got a graphics card score of 26,494 points. In addition, in the NVIDIA DLSS feature test project, this time using The beta test version includes a new DLSS 3 test. In the test, it can be found that DLSS 3 can indeed perform better than DLSS 2. According to the test results, the higher the resolution, the more obvious the improvement in the number of frames of DLSS 3.
Game performance test
In the game test section, select “Electric Rider 2077”, “Watch Dogs: Freedom Legion”, “Polar Howl 6”, “Thriller: Exile”, “Assassin’s Creed: Viking Age”, ” Rainbow Six: Escape from the Restricted Area” and “Forza Motorsport: Horizon 5” were tested, and the test resolution used 1440p and 2160p for players’ reference.
In the AAA game part, since the performance of RTX 4090 is more than 1 time higher than that of RTX 3090 this time, AAA masterpieces can easily achieve an average performance of more than 60 frames with full special effects at 2160p, which is a competitive shooting game that does not eat performance. , you can have more than 2160p 144fps performance.
The light chasing test part is tested with 4 games, “Electric Rider 2077”, “Watch Dogs: Freedom Legion”, “Polar Cry 6”, and “Thriller: Exile”.
In the test of the light chasing game, the tested 4 games do not have DLSS or FSR but actually have a good frame rate performance. Among them, only the frame rate performance of “Dian Yu Ren Ke 2077” is relatively low, and after the DLSS function is turned on, in In DLSS 2 mode, the performance of breaking 100 frames can be achieved. In addition, this time I also used the beta version of “Dianyu Renke 2077” to measure DLSS 3. Under the actual measurement, the number of frames can be further improved, about 2 times under 1440p. , 2160p can achieve 3.5 times performance improvement.
Temperature and power consumption
The temperature and power consumption test is mainly based on the highest value of the entire platform. It is equipped with an i9-12900k processor. Through FurMark, Time Spy Stress Test, and GPU-Z, the temperature is simulated under high load, DX12 games and standby conditions. and power consumption. ROG Strix GeForce RTX 4090 OC operates at a temperature of 40 degrees and consumes 110 W of power on the entire platform; when the Time Spy Stress Test is running, the temperature is 64 degrees and the power consumption of the entire platform is 557 W; when FurMark 4xMSAA is running, the temperature is 66 degrees, the power consumption of the whole platform is 543 W.
ROG Strix RTX 4090 OC Summary
This update of the RTX 4090 brings strong performance, which is followed by a larger graphics card size. This time, the ROG Strix RTX 4090 OC has a newly designed radiator, although the size has reached 3.5 card slots, 35 cm long, in terms of heat dissipation, the temperature of the graphics card can be suppressed to around 65 degrees, which is equivalent to using a larger size for better heat dissipation performance. It may be necessary to pay attention to whether the size of the case is large enough, and if the accessories are included The graphics card bracket does not fit your case, you may also need to prepare a suitable graphics card bracket for this graphics card.
In terms of performance tuning this time, Boost clock pre-overclocking to 2640 MHz is basically the first class among the RTX 4090s. If players want to conquer the new generation of the strongest graphics cards at once, ROG Strix RTX 4090 OC is a good one you can consider.
