Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizens Wu Yanzu in South China for the delivery of clues! CTOnews.com news on November 12, @ Pugetsystems put seven NVIDIA GeForce RTX 4090 GPU together at the same time, and passed the OctaBench benchmark test, which is a little crazy.

Using a 64-core AMD Threadripper PRO 5995 WX processor, an Asustek Pro WX WRX80E-SAGE WIFI motherboard, 128GB DDR4-3200 memory, 2 TB Samsung 980Pro SSD and four Super Flower LEADEX power supplies (with a total power of 6400W), the entire system costs about $30000.

It is worth mentioning that because a total of 28 8pin connectors are required for seven NVIDIA GeForce RTX 4090 graphics cards, he can only use four power supplies at the same time.

In order to make the whole system run smoothly, instead of using PCIe 4x16 mode, he used several transfer lines to make it run in PCIe Gen 3.0x16 mode.

CTOnews.com learned that with a card rated at 450W, seven NVIDIA Geforce RTX 4090 graphics cards would eventually reach 3150W, but considering that the rest of the system also needs power, 6400W must be sufficient.

From the end result, the power consumption of seven RTX 4090 graphics cards is 2750W, while the idle power consumption of seven cards is almost as high as that of a RTX 4090.

In terms of performance, OctaneBench (enabling RTX) shows a very obvious growth relationship, 7 cards can basically bring 4.56 to 6.9 times the performance, which is more reasonable than the SLI performance loss in the "four-way Titan" era (and this generation of consumer-grade graphics cards no longer support SLI).

In addition, the reviewer ran the OctaneBench test with eight NVIDIA GeForce RTX4090 GPU, which finally showed nearly 8x linear growth performance, which also shows that RTX4090 can bring very good multi-card scalability.

Therefore, if you have similar job requirements, it may be a good choice to use multiple graphics cards.
