Which is better for a GPU server?

The Supermicro H12SSL-NT, with five PCIe 4.0 x16 slots versus fewer on the ASRock. If you only need one or two GPUs, the ASRock saves money.

Is the Supermicro worth the extra $570?

Only if you would otherwise buy an SAS HBA and a 10GBase-T NIC. Add those to the ASRock and the gap narrows; skip them and the ASRock is the better value.

Do both support EPYC 7003 with 3D V-Cache?

The ASRock explicitly lists 7003 with 3D V-Cache. The Supermicro lists EPYC 7003 generally; check the CPU support list for the exact SKU before buying.

Which has better storage options?

The Supermicro, because SAS and SATA work without an add-in card. The ASRock handles SATA and M.2 natively and needs an HBA for SAS.

Which is easier to manage remotely?

The Supermicro, whose IPMI/BMC is well documented. The ASRock has a BMC too, but documentation is thinner.

Can I use the same DDR4 memory in both?

Yes. Both take registered ECC DDR4 in 8 DIMM slots, so a matched kit carries over between boards.

Supermicro EPYC 7002/7003 Single Socket SP3 DDR4 SATA SAS PCI-Express M.2 Supported ATX Server Motherboard - MBD-H12SSL-NT vs AsRock Rack ROMED8-2T/BCM Server Motherboard Single Socket SP3 (LGA 4094), supports AMD EPYC 7003 (with AMD 3D V-Cache Technology)/7002 series processors

Buy the ASRock Rack ROMED8-2T/BCM for a standard EPYC server build: it costs $657.00 at DirectDial as of November 3, 2026, against $1,228.62 at aloinfousa.com for the Supermicro. Pick the Supermicro H12SSL-NT only if you need onboard SAS, dual 10GBase-T LAN, or its IPMI management stack out of the box. The ASRock gives you the same socket, 8 DIMM slots and PCIe 4.0 for roughly half the price.

Today the AsRock Rack ROMED8-2T/BCM Server Motherboard Single Socket SP3 (LGA 4094), supports AMD EPYC 7003 (with AMD 3D V-Cache Technology)/7002 series processors costs $571.62 less at its best price.
