Question High-end 870 or 890 for a unique system

[thegreatdelcamo]

Okay MB experts… Big Golf Simulator…

Talking about 890 or 870. With at least

1. 10 USB ports on rear, ideally 14 (I need at least 12, but can use internal connectors to add a 4-port extension.)
2. Two PCIe 5.0 slots that will run 8x8 (will run a 4080 Super on top, a 4070ti on bottom.)
3. Another PCIe 4.0 slot for a POE card running two high-speed swing cameras.

Ideally, the lower GPU will not crowd out the bottom PCIe 4 slot (I’m looking at you, ProArt 870?) But if it does, I need to find a way to mount everything.

I would go Intel 890, and the ROG Maximus z890 Apex looks really good, meeting all my criteria (the 4.0 slots being wisely placed above the 5.0 slots). My only concern: it is Intel, which brings two issues—one, the company is in serious trouble, and two, the new chips underwhelm. Still, I like the lower power, and arguably for GSPro, which is GPU driven, so maybe I don’t need a “gaming” monster…

Thoughts?

890's would have an advantage over the other

Thanks for the comment. Would you be willing to provide your reasoning? Are you speaking in general or with respect to a specific MB?

Generally, z890 chipset provides more PCIe lanes, and ultra200s provides Lightning5 controller by itself, while AMD's x870=b650e+usb4(consuming 4x PCIe lanes), x870e=x670e+usb4(consuming 4x PCIe lanes).
Meanwhile, ultra200s cpus are not that powerful as ryzen9000.

Ah... That is relevant information. I just had Copilot make a chart for me. I'd written Intel I-9 chips off for a number of reasons, but importantly because they only had 16 5.0 lanes...

This would explain why I see so many more USB ports on the Intel boards. So, thanks for bringing this to my attention.

PCIe 5.0 Lanes (CPU) PCIe 4.0 Lanes (CPU) PCIe 4.0 Lanes (Chipset) Total PCIe Lanes

Intel Core Ultra Chip	24	0	20	44
Intel Core i9 Series	16	4	24	44
AMD Ryzen 9000 Series	24	0	12	36

Summary​

• Intel Core Ultra Chip: Offers a total of 44 PCIe lanes (24 PCIe 5.0 + 20 PCIe 4.0).
• Intel Core i9 Series: Also offers a total of 44 PCIe lanes but allocates them differently (16 PCIe 5.0 + 4 PCIe 4.0 from CPU + 24 PCIe 4.0 from chipset).
• AMD Ryzen 9000 Series: Offers 36 PCIe lanes (24 PCIe 5.0 from CPU + 12 PCIe 4.0 from chipset).

Besides, most non-usb4/lightning5 usb ports are offered by chipsets.
Why do you need PCIe5.0x8 for 40-series graphics card? These cards doesn't support them, the only graphic card support PCIe 5.0 is Moorethread's MTT S80.

Maybe the Biostar x870e valkyrie is your best choice.

For your two graphics card and one POE card:
- It offers a PCIe5.0x16 divided into 2x PCIe5.0x8 in slot2 and slot5, which is capable for your 4080s&4070ti.
- Additionally, there's a PCIe4.0x16(actually 4.0x4, physically x16) on the slot7, which is capable for your POE card. If your 4070ti is a two-slot card, it's perfect for you.
Installing the POE card will disable the M2 slot above the bottom PCIex16 slot, remaining three M2 slots.

The only problem is that it only offers 8xUSBA+2xUSB4TypeC, maybe you can use a hub for extra usb ports.
