You meant 4x PCIe slots? That must be a joke. Even x299 with only 28 PCIe lanes has 7... TRX40 could happily support 8x PCIe 3 slots, but nobody makes such board.
- onli 7y agox299 does not have 4xPCI-E 4.0 x16. It technically can't support that. But no, I meant basically everything else. The amount of ram, USB, SATA and M.2 slots as well as USB headers is nice, compared to regular consumer board at the very least.
- bitL 7y agox299 gives you 7x PCIe 3 x4 slots. That might be surprisingly good enough even for GPUs. And most motherboards can reconfigure number of lanes per slot. Now imagine having an 8-slot motherboard for 3990X that could be configured to e.g. 4x PCIe 4 x16 or 8x PCIe 3 x16. Wouldn't you like such motherboard? For Deep Learning I don't really care about PCIe 4.0, but I do care about being able to fit as many GPUs in as I can (they talk to each other outside PCIe anyway). With TRX40 I am limited to 4 GPUs. Even PCIe 3 x8 is good enough for DL.
