LGA 1700 motherboard for dual GPU setup

I want to setup a dual/multi gpu setup, will be using 13600k, Rx 6600 xt, RTX A2000

Mostly the second (chipset) PCIe x16 slot that operates at x4 and not x8 so is it worth?

any good motherboard for this?

Any motherboard which supports bifurcation is good. Just ensure the intended slots run directly from CPU lanes, not chipset. You can run a max of 2 GPUs in x8/x8 mode from the 13600k.

thanks, however i haven’t found any x8/x8 supported mobo or should i say x8/x8/x4x4 as there will be 2nvme

13600k has only 20 PCIe lanes AFAIK. Out of which 4 are reserved for the chipset. If you run 2x NVME, they’ll run in x4/x0 mode (with fast switching).

For the remaining 16 lanes, genAI says Gigabyte Z690 Aero D and ASUS ROG Strix Z690/Z790-E support bifurcation in x8/x8. Double check their spec sheets though.

I was in the market for something similar a while back. My options were Asus w680 (around 34k), Asrock z690 taichi ( there’s one on flipkart which dropped under 30k quite a few times), Asrock z790 taichi lite, MSI z690 Ace (DDR4/DDR5) among others.

There’s also Asus Z690 Maximum from refurbco (@aasimenator).

Check the spacing between the slots according to your GPUs. Intel alder lake supports 20 PCIe lanes and 8 DMI lanes so x8/x8 with 2/3 nvme should be supported in aforementioned motherboards.

i don’t think can spend that much. how much performance loss i will get with x4 for a2000?

What’s the intended usecase? If inference then slot speed isn’t that big of a deal.

Between 5 to 10% less depending upon the application.

purchased B770-P wifi DDR4 and it has perfect pcie slots including two x16 + x4 speed. strange i don’t see any different in furmark benchmark when i put it on x1 speed slot.
