Deep learning dual-card 4090 build-up solution
A happy alchemist
The AMD 7950x + dual 4090 solution is less than 50,000, currently the most economical dual-card artificial intelligence server solution
Motherboard: ASUS (ASUS) ROG STRIX X670E GAMING WIFI motherboard 3999 yuan (need to support dual PCIE channel split into x8)
CPU: amd 7950x 3500 yuan
Memory: 32G 4 128G DDR5 600x4 2400 yuan
Chassis: Chaser 620PC 800 yuan
Graphics card: 4090 water cooling x 2 1.5wx2 30000 yuan
Power supply: Great Wall Dragon 2000w 1200 yuan
Hard disk: ssd 2T 450 yuan, 16T mechanical 1900 yuan, total 2350 yuan
Total price: within 45000 yuan.
Other notes: The motherboard is a consumer-grade motherboard that supports splitting of two PCIE channels. The speed of PCIE 4.0 x8 is sufficient for 4090 to run, and the performance drop is negligible. Motherboards that do not support dual-slot channel splitting cannot be used, and the performance of the second card will be greatly reduced.
The graphics card can use colorful water gods and the like, only double slot width. Pay attention to whether the chassis can be installed with two 360 cold radiators. At this time, it may be necessary to use air cooling to cool down the CPU (it is not easy to install a CPU cold radiator, it would be better if it can be installed)
