X670 or B650 for a 7800X3D

[Jamie Tuz]

Hey,

 

Looking to build a new PC for gaming with a 7800X3D CPU, however I'm a bit lost with what chipset to go with. B650E looks like the good choice but it doesn't appear to be in stock at all in my region.

 

I probably won't overclock, at least not until its older and I need that extra bit of performance to keep up. Not too stressed about the extra cost of X670 if it's a worthwhile upgrade.

 

Is it worth spending extra for a PCI-E 5 SSD and getting X670 board or is it unnecessary for gaming? (I live in AUS, so my internet speed is going to be quite slow and certainly won't be anywhere near the drive's speed either way)

 

TIA

I have built plenty of AM5 systems (50+ )  and mainly gone for the B650 boards.

If you don't need PCIE 5 and some of the extra the X670 brings, get a B650 and save some money.

 

I use a B650 with my own 7700x and plan on updating the BIOS and put a 9800X3D into this board whenever that CPU comes out.

The choice between B650 and X670 has nothing to do with overclocking or what CPU you're going to use, the chipsets dont care about any of that. They can handle whatever AM5 CPU you buy. 

 

X670 and B650 differ primarily on I/O options with X670 favoring more of the consumer level workstations. 

 

You're not gaining performance by the chipset decision.

Almost never, for anyone, especially someone that isn't be paid to move massive files around all day as their job. I firmly believe Gen5 drives have zero place in the consumer space, they offer ZERO benefit over Gen4 for 99% of people.

 

What is your budget and what do you plan to do with the PC and someone can point you towards a board.

You should honestly read a few of the threads in this subforum, as the B650 boards are recommended literally hundreds of times, and covering your concerns.

 

Short answer:  B650.  PCIe 5 SSDs are unnecessary for gaming.

 

Tho for $219 get this...

PCIE5 will be mostly irrelevant for most people for years to come... when it starts to become relevant PCIE6 will be already out for several years... 

 

its basically just a money making scheme releasing new PCIE gens early atp

Pretty much this, well almost completely. There is ONE real reason someone would choose an X670 board over a B-650 other than PCIE lanes, PCIE generation, or I/O options and features...

 

That would be VRMs, Power Delivery, and overall quality of the board (6-Layer PCB vs 4-Layer, for example). While not a hard and fast rule, most of the time, X670 boards have higher quality PCBs and can deliver more power to the CPU through more robust VRMs and Power Phases/Stages.

 

This can actually make a small difference in performance, but only for overclocking and only for the highest-power CPUs (7950X/9950X). You only need very basic VRMs and Power Phases/Stages for a 7800X-3D simply because its a low-power chip. I have a 7800X-3D and even with maxed out PBO, limits removed and some custom tweaks that push mine to 4950 MHz All-Core frequency, the total CPU Package Power is still only just shy of 90 watts. Just about any VRM and Phase can handle the 7800X-3D all the way down to the A620 Boards.

 

So ya, I have a B-650 for my 7800X-3D because anything more is literally just a waste of cash. There are a couple boards that can unlock the hardware limits of 3D V-Cache CPUs for additional overclocking options but those are far more expensive and the performance increase is minimal.

This isn't a concern for the majority of B650 boards that aren't the absolute bottom of the barrel cheap stuff. $125 will get you something that'll handle a 7950x/9950x w/ PBO without an issue. 

 

7800x3D is essentially nothing power draw wise to even the cheapest boards.

Exactly, which is why I said even A620 boards won't have a problem. But ya I meant overclocking beyond just PBO - ya know, going to the absolute limits. Either way - agreed
