Which Intel Arc B580 for Darktable?

Unfortunately I am limited by the brand. Only Asrock and Sparkle are possible.

The challenger is the only one with 2 slots. All other need 3 slots.

All Sparkle need 2.2 slots

I need the power of the graphics adapter for darktable only. 2 slots would be better, so I have a slot free, no idea if I need this PCIe 2 slot ever, I need 1 additional PCIe slot with a MSI MAG X670E TOMAHAWK WIFI. 4th slot has sharing, so unusable, 2nd would be blocked with with a 3-slot graphics adapter and 3rd is used with PCI x1.

it doesnt really matter. also properly check for

a) which NVME slots might do lane sharing with your main GPU slot
b) which usb/sata/nvme devices are lane sharing with the other slots
c) how many lanes the lower slot has at all.
d) what devices to do you think to use in the other pcie slots?

Don’t know, maybe none.

It depends, if I don’t use PCIe-4 i can use M.2-4 without sharing.

M2.-1 has PCI5.0, but I use NVME for PCIe 4.0 only, so I think to let it free for later use.

M2-2, M2-3 and M2-4 are PCIe 4.0 NVME.

No idea how to find it out.

Firewire, which is x1, put in Slot 3.

the manual lists which devices share how many lanes. and also how many lanes each slot has.

be careful with using m2_2/m2_3, they might share lanes.

also firewire in 2025? :slight_smile:

i would stick that in pcie_4 tbh.

I havent used any PCIE slots in years besides the main GPU.

For connecting an old camcorder.

Didn’t find this in the manual.

*PCI_E4 & M2_4 share the bandwidth. M2_4 will run at x2 speed when installing device in the PCI_E4 slot.
