Minisforum BD790i review: Mini-ITX mainboard with an AMD Ryzen 9 7945HX and PCIe 5.0 as a basis for small gaming PCs

[Redaktion]

The Minisforum BD790i mainboard promises a great deal of performance and, as a result, could be an excellent basis for compact Mini-ITX PCs. We took a look at the mainboard, which is equipped with an AMD Ryzen 9 7945HX ex works and is aimed specifically at users with high demands. In our test, we analyzed the system's performance during intensive tasks and, in combination with an Nvidia GeForce RTX 4090, we also took a look at its gaming performance.

Can anybody explain to me why this board has 10x the dpc latency of its predecessor, when it has the exact same processor?  The newer version of the 790 is better, but still 3x slower.

Are there variables in the DPC latency test that could account for this??  Different OS, drivers, peripherals?  It's wierd to publish this number with no suggestion what causes it, when it is so widely divergent from one model to the next.  It's great that NCHK tests for dpc latency, but it's frustrating to have no further information about it.

I need a low-latency sff machine for live audio, but the bd 770i is no longer available.... sadly, since it is among the lowest latency machines NCH has tested.  Nothing else of that format from the past 5 years is even close.
