Gigabyte B550 Aorus Pro Preview

PCI Express Layout

Without any concrete information about pricing yet the best we have to hope for is that, due to its position in the product stack, B550 boards will be cheaper than their X570 brothers. The rest of the components on the boards will all come down to each individual manufacturer and how they decide to spec them, but how have AMD made B550 cheaper? In short there are NO PCI Express 4.0 lanes available on the chipset compared to up to 16 available on X570. Dont get confused though, you still have the PCIe 4.0 lanes on the CPU, but where the chipset only has PCIe 3.0 lanes to offer this means we have to watch out for where the M.2 slots on the board are wired to.

The Aorus Pro is relatively easy, in that the top one is PCI Express 4.0 because it's wired into the CPU directly, whilst the lower is the more familiar PCI Express 3.0 because it is wired into the chipset. It is worth noting though that if you look in the block diagram the lower slot does share the bandwidth via a switch with the lowest PCIe x16 slot (this is only wired as a 4X though). The use of a switch makes life easier as it means it shares bandwidth rather than you having to choose which one you want to use.

Only reason I can think of for PS/2 to be making a come back is security.
I have worked in business where the IT department have disabled all USB connections to reduce the risks of data theft and malicious software being uploaded. I have heard that this connection is better for competitive gaming too due to the reduced latency and ability to send multiple key strokes simultaneously, I have not noticed a difference but there again im not s1mple lolQuote

No. Apparently there was too much cross talk on the traces. It would have been a big issue for 4000. Well, that is what I have been told any way.

Shame, they were stunning boards.Quote
