Performance: Storage and Network
The C9Z790-CGW supports only one M.2 PCIe 4.0 x4 socket. It’s quite disappointing as most other brands promote three, four, or even five M.2 sockets, and all of them are at least in the 4.0 standard. It doesn’t change the fact that the M.2 performance is as high as it should be. The used Kingston Fury Renegade 2TB SSD achieved about as high scores in the PCMark 10 Storage Benchmark as on other Z790 motherboards.
Team Group Delta 1TB SATA SSD reached about the maximum bandwidth of the SATA interface in CrystalDiskMark. One more great result.
Here is also Patriot PXD 1TB USB 3.2 Gen2 SSD. USB results are about as high as they can be.
Since the 10GbE LAN environment wasn’t prepared for this test and the LAN performance on Supermicro motherboards was always exceptional, then we focused on the wireless connection.
The C9Z790-CGW supports WiFi 6E, and the same as in the previous Z790 motherboard reviews, our maximum bandwidth was around 1.25Gbps, while the specifications suggest 1.3Gbps as a peak. The test was performed between two computers working in WiFi 6 standard and a Netgear router. Considering the multiple networks in the area and thick walls, the result is pretty good.
The CZ790-CGW provides multiple fast connections, and it’s one of its strongest sides. If you are searching for an affordable motherboard that you can use for gaming but also as a workstation, then it’s the way to go. The SUPERO once again delivered a well-equipped and fully stable motherboard.
