B550 or X570

[NoahEriksson3]

Budget (including currency): Not relevant

Country: Sweden

Games, programs or workloads that it will be used for: Gaming, mostly triple AAA games like Battlefield and other.

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): 

I was wondering if it worth paying the extra for a X570 motherboard over a B550. I was looking at the Asus Rog Strix B550F Gaming and the Asus Rog Strix X570F Gaming.

It depends on what features you want on the motherboard. X570 typically comes with more I/O, faster interfaces and better components for overclocking. If you only plan on gaming with your PC, I'd recommend that you get a B550 board as the features on X570 is not used as often (if at all) for gaming.

If it's a new design with x570 or x570s it's worth analyzing features and all that. 

If it's an older x570 design, most of the time B550 motherboards in similar price range are simply better. 

 

The only benefit of x570 is a couple extra pci-e lanes provided by chipset, and the fact that all pci-e slots are pci-e 4.0. B550 still gives you pci-e 4.0 to the video card and first M.2 connector  (because those pci-e lanes come from CPU), but the 8 pci-e lanes from chipset are just pci-e 3.0  (and these lanes typically go to the bottom pci-e x16 - electrically x4 - and the 2nd M.2 connector)

Oh yeah, one benefit that actually may matter to some is the ability to split the x16 from cpu into 2 pci-e x8 slots ... but SLI is dead, crossfire is dead... 

 

In my opinion you're not missing much - 4 GB/s is still plenty for the 2nd m.2 connector, and also it's not like you really need pci-e 4.0 lanes for that bottom slot... except a video card like 6500xt, pretty much anything (usb controller, 10-25g network card, raid/hba controller can work just fine with the 4 GB/s of bandwidth 4 pci-e 3.0 lanes give)

 

Between those 2 asus boards .. 

 

the x570 model has the  pci-e x16 splittable into 2 pci-e x8, has 8 sata instead of 6  (but I think some will be disabled if you use m.2 connectors), 

x570 has 8 usb  (4 5g , 4 10g) , b550 has 8 but less 10g (2 480mbps, 4 5g , 2 10g ) 

x570 has gigabit card, b550 has 2.5 gbps

Okay, then I think I will get the B550 board because I don't really plan on overclocking the CPU at all and I will mostly game. I don't really need more than one PCIE 4 m.2 because I will only have one big ssd and then hard drives. Thank you so much for the help.

Yeah I don't really think I need those extra PCIE 4 Slots, I am just gonna game and only need one M.2 PCIE 4 slot and just gonna get HDD for mass storage. I am only gonna run a RTX 3080 so yeah I think i'm gonna get the B550 board. Thank you for the help.
