NVIDIA’s new generation GeForce RTX 4090 graphics card is quite powerful. I believe everyone knows this, and the power consumption should not be underestimated. A while ago, there were many cases of melted power connectors abroad. A single card is already so scary. Recently, foreign computer companies Pugetsystems I even did a crazy thing. I installed 7 NVIDIA GeForce RTX 4090 into a computer and then tested the performance. It was really powerful, but the power consumption was also super scary, nearly 3000W. It felt like it was going to burn just by looking at it.
A foreign actual computer is equipped with 7 NVIDIA RTX 4090 graphics cards. Not only is the performance extremely powerful, but the power consumption is nearly 3000W.
Pugetsystems recently assembled a super crazy computer, equipped with a 64-core Threadripper PRO 5995 WX processor, using the ASUS Pro WX WRX80E-SAGE WIFI motherboard, 12GB of DDR4-3200 memory, 2TB Samsung 980 Pro SSD, and “4 1600W Super Flower LEADEX power supplies”, which means a total of 6400W The number of power supplies is really scary, but since you want to drive 7 NVIDIA GeForce RTX 4090 graphics cards, of course you need such a large power supply.
The price of the entire computer is approximately US$30,000, or approximately NT$930,000.
The 7 NVIDIA GeForce RTX 4090 graphics cards put together are really spectacular. In addition, you can also find that 4 are founding editions, 1 is ASUS TUF Gaming, and 2 are PNY XLR8:
Pugetsystems has tested and counted the performance and power consumption of each additional NVIDIA GeForce RTX 4090. The picture below shows the total system power consumption. The 7 graphics cards have reached 2750W, which is close to 3000W. Foreign media also pointed out an interesting point, that is, the standby power consumption of 7 graphics cards is almost the same as the power consumption of 1 graphics card under load. Normally running a game is about 300~400W:
In the OctaneBench 2020.1.5 test, every time one RTX 4090 is added, the performance increases exponentially. With seven RTX 4090s, the performance is almost increased by 7 times. This performance is very impressive:
DaVinci Resolve V0.93.1 seems to be at its limit after adding 6 pictures, and it cannot be improved. The measured performance of 6 pictures and 7 pictures is the same:
RedShif is improved by about 4.6 times:
V-Ray is improved by about 5.1 times in CUDA mode, and more than 6 times in RTX mode:
Although the computer performance of seven RTX 4090 graphics cards is really powerful, and the performance in content creation and graphics calculation capabilities is also quite impressive, no one should do it. On the one hand, the power consumption is too terrible, and on the other hand, no game currently supports so many graphics cards. Just one RTX 4090 should be able to play all the current 3A game masterpieces at the highest settings. It is too wasteful to use so many.
