GeForce NVIDIA Ampere
Puget Systems has published an interesting article showing what they are capable of four Nvidia GeForce RTX 3090 together inside one workstation . The test shows the potential of the new flagship from Nvidia and above all how they scale multiple solutions in parallel with software deputies to content creation.
Quattro RTX 3090 struggling with professional software
With a GA GPU 102 equipped with 10496 CUDA core flanked by 24 GB of GDDR6X memory, the GeForce RTX 3090 from Nvidia is arguably the fastest card in the world. In our review we have seen how its potential in terms of gaming (at least at current game resolutions) is limited, while there are areas such as rendering that are able to adequately exploit the power and the large amount of memory available.
Puget Systems has published a series of tests that see four GeForce RTX 3090 (specifically Gigabyte “Turbo Edition”) on board an Asus WS C motherboard 422 Sage with CPU Intel Xeon W 2255 , 128 GB of memory DDR4 – 3200 and a pair of EVGA power supplies from 1600 W . Puget detected the performance of this workstation with OctaneBench, V-Ray Next, Red Shift and a custom load for DaVinci Resolve (we publish only some of the tests, the others can be found in the original article).
As there is no suitable NVLink bridge, the four video cards are divide the loads by communicating via the PCI Express interface . The RTX 3090 does not support multi-GPU configurations beyond two cards, but this only applies to software that require SLI technology. The software used for testing simply uses as many GPUs as there are in the system.
As can be seen from the graphs, we can see an almost linear scaling in OctaBench and V-Ray Next among the four RTXs 3090, with unprecedented performance . Puget Systems has also released consumption data for the entire system, with a peak of 1717 W which can be reduced by 50 – 75 W using two power supplies to improve efficiency. Lowering the power limit to 300 W yes notes a further decrease in platform consumption, without a significant decline in performance.
The surprising aspect is that the cards did not exceed operating temperatures of 80 ° C , although the blower project produced (as you can hear in the video above) a lot noise , with the fans engaged at 80 – 90% of their operating range.
