What do you think would happen if we put seven GeForce RTX 4090 graphics cards on one system? very well; The PugetSystems collection has done this And installed seven RTX 4090 graphics cards on one system and tested its performance in various benchmarks such as OctaneBench!
Testing seven RTX 4090 graphics cards on one system
The GeForce RTX 4090 graphics card is currently the most powerful graphics card in the world, but PugetSystems has gone one step further and installed seven of these graphics cards on one system. This system is also not an ordinary system and includes parts such as AMD Threadripper Pro 5995 WX 64-core processor, ASUS Pro WC WRX80E-SAGE motherboard, 128 GB DDR4-3200 memory, 2 TB Samsung 980 Pro SSD and four – yes four power supplies. 1600W Super Flower LEADEX is equipped with a total power of 6400W. You might just be interested to know that powering these seven RTX 4090 graphics cards requires a total of 28 8-pin cables!
The RTX 4090 graphics card is a 450-watt graphics card by default, and normally the energy consumption of seven of them should be around 3150 watts, but the rest of the parts of this unusual system also consume electricity. These seven graphics cards also include four devices from the Founders Edition series and three devices from the XLR8 and TUF series of Asus and PNY companies. PugetSystems has also shared the total price of the system with us – the total price of the system’s components is around $30,000.
In order for this system to work without problems, several riser cables were used and the interface of the cards was also PCIe 3.0 x16 during the test, because the PCIe 4.0 interface caused problems in the system’s operation. After everything worked properly, the total consumption of these seven graphics cards under load reached 2750 watts. An interesting point is the total energy consumption of these cards in idle mode. These seven RTX 4090 graphics cards draw almost as much power at idle as a full RTX 4090 graphics card, something like 300-400 watts.
Performance of seven RTX 4090s in OctaneBench and other tests
In terms of technical performance, the OctaneBench benchmark with RTX on shows a good distribution of performance across all seven RTX 4090 graphics cards. In the V-Ray benchmark, we see a 6-fold performance improvement with RTX on and a 5-fold performance improvement in CUDA mode. RedShift and DaVinci Resolve benchmarks also provided 4.6x and more than 5x performance with this combination, respectively.
Such an interesting demonstration better than anything shows the enormous potential of the RTX 4090 graphics card in content creation. Of course, such a system is not practical at all, and content producers prefer to go for more professional RTX Quadro graphics cards with NV-Link interface support and less setup hassles. On top of that, there are no games that can even support two RTX 4090 graphics cards, let alone seven!
