Four NVIDIA RTX 3090s in one PC, the brutality of Purge Systems
Although we usually talk about gaming hardware, there are solutions for all types of markets. Even hardware initially intended for gaming can be a very good solution for the professional segment. Puget Systems has introduced a system based on an Intel Xeon Cascade Lake and a total of four Gigabyte RTX 3090 Turbo graphics. Of course, this system has not been developed for gaming, but for professional tasks.
NVIDIA's new graphics cards offer enormous computing power. This is why Purge Systems has developed a professional team based on RTX 3090 graphics. But it is not the only peculiarity of this system, and it also integrates two power supplies. And of course, feeding an Intel Xen Cascade Lake and four RTX 3090s is not easy.

Purge Systems presents a team with four NVIDIA RTX 3090
This impressive system has a 2255-core, 10-thread Intel Xeon W20 processor. This Intel processor works at a base frequency of 3.7GHz and comes in Boost mode at 4.5GHz. The ASUS WX C422 SAGA has been used as the motherboard. The processor is complemented by 128GB DDR4 @ 3200MHz. Two 1600W EVGA power supplies have been used to power this monstrous system.
The graphic power is provided by the aforementioned four Gigabyte RTX 3090 Turbo graphics, with a blower type heatsink. These graphs have been used, since for this type of assembly they are more efficient and have fewer temperature problems. The air is channeled towards the rear of the chassis and allows for better cooling in systems where the graphics are so close together.
This entire system is designed for rendering and for this reason specialized software has been used. OTOY OctaBench, V-Ray Next, RedShift, and DaVinci Resolve tools have been tested. For OctaneBench and V-Ray software we see a linear performance improvement as graphics are added. RedShift and DaVinci offer the same performance with three graphics as with four graphics.
This system at full load has a not inconsiderable consumption of 1700W. But the problem is not in the consumption, but in the loudness that this system reaches, as you can hear in the video. The truth is that it even seems that the system is going to take off.
