X670E-F or B650E-E Whats differences? Worth the extra money?

[PaulW]

Hi

i am stuck with which one to go with , i mostly do 3D work for games dev and i am looking to pair it all with a 4080 for work and playing games.
what are the main differences between the two and is the X670E-F worth the extra money?
i read the PCI-E lanes are different would this make a difference? i think the X670E-F has 44 and the B650E-E has 36.

Thanks and happy Saturday

I think it's just more power stages and something about dual layer PCB and more high speed usb and sata ports? I went with a Rog Strix 650 e-e myself that has everything I can imagine needing.

You get more slots for pcie 5.0 cards and nvmes and better bandwidth at x670e. At the moment there are no pcie 5.0 GPUs or NVMEs although the NVMEs will be out soon at PCIE5.0 x4.

X670e generally has better RGB if that’s important to you and generally better VRMs and a better PCBs although these will be over engineered anyway. The premium x670e boards also have USB 4.0 slots. So not much difference for gaming really.

I'm not sure the bolded part is correct and may just be model specific. My 650 Rog Strix E-E has two PCIe Gen 5 slots, two Nvme gen 5 slots and two Nvme Gen 4 slots.

Edit - I think on average the x670e has more slots as the b650e-e models tend to be less expensive and but I checked again and it seems that the premium models b650-e like the strix-e, as you said, have as many slots as the x670e which is quite impressive.

I think the main difference is that the b650e only has one chipset compared to the x670e which has a dual chipset so you will have a restricted bandwidth compared to the x670e which may or may not be important in the future depending on your needs or what you want to upgrade to with regards to NVMEs.

X670e has more USB slots as well. So not a a great difference.

once you start populating the slots , things can start getting disabled or run at reduced speeds would have to look at the manual

This gives a good comparison of the chipsets specifically. How the boards are setup to align with this will very much be vendor specific (i.e. you will need to check the listings carefully to ensure they have enough SATA / NVME / Expansion slots / USB etc to meet your needs).

AMD X670E vs X670 vs B650E vs B650

AMD has launched their latest Ryzen 7000 Series processors, which use a new socket design and thus require new chipsets and motherboards. To fill this role, AMD is offering two chipset models with two variants each. How do X670 and B650 compare? And what differences are found in the "extreme"...

www.pugetsystems.com

At a high level it goes:

X670-E - Gen 5.0 PCI-E x16 for GPU, PCI-E Gen 5 for primary NVME (x4) and x4 GPP) - 44/20(5) PCI-E / 12 10Gbps USB / 2 20Gbps USB / 8 SATA
X670 - Gen 4.0 PCI-E x16 for GPU, PCI-E Gen 5 for primary NVME (x4) and x4 GPP) - 44/4(5) PCI-E / 12 10Gbps USB / 2 20Gbps USB / 8 SATA
B650-E - Gen 5.0 PCI-E x16 for GPU, PCI-E Gen 5 for primary NVME (x4) and x4 GPP) - 36/20(5) PCI-E / 6 10Gbps USB / 1 20Gbps USB / 4 SATA
B650 - Gen 4.0 PCI-E x16 for GPU, PCI-E Gen 4 for primary NVME (x4) and x4 GPP) - 36/0 (5) PCI-E / 6 10Gbps USB / 1 20Gbps USB / 4 SATA (PCI-E gen 5 is listed as optional for the NVME)

So generally:

X670-E - All PCI-E Gen 5 with lots of of I/O
X670 - As above but drops Gen 5 for GPU
B650-E - Like X670-E but halves the available I/O
B650 - All Gen 4 with half the the I/O of the X670.

Sweet spot for most people is either the X670 or B650-E although pricing plays a much bigger factor as they all seem to overlap which is somewhat moronic. For example you can get an Asrock X670-E board for less than a lot of B650-E boards.

I have the Asus B650E-E with a 7950X, and it’s been very stable. The B650E-E has more than half the IO, its 36 vs 44 lanes. It drops 8 PCI-e lanes vs the X670E. The B650E-E has 4 m.2 ports ,2 gen 5, 2 gen 4 but if you use the second gen 5 port it split the GPU down to 8x gen 5. For me, that’s not a big deal.

Yep exactly the same as mine. 2 pcie gen 5 slots. 2 gen 5 nvme and 2 gen 4 nvme. Only when the 4th nvme slot is occupied does the pcie go to 5x8 (so 3x16 effectively for a gen 4 GPU, which is a loss of 1-3fps).

If the next gpu cards are gen 5 we can still run at 4x16 effectively with all 4 slots occupied.

I don't blame people for been confused. In my opinion high end b650e boards beat *a lot* of 670 ones, and in many cases save £200+

I think one aspect that potential users of these boards might be overlooking as wel when looking at the available lanes, etcl, should be feature vs expansion capability.

I'm pretty sure everyone has seen the direction GPU coolers have been going in the last few years. Gone are single slot cards that use air cooling that is even remotely modern. Dual Slot cards are quite the norm but mostly loud as heck unless if it's a low end card - but then those cheap low end cards are also saddled with poor cooling parts (and no one wants noisey parts). And multi-slot GPU's are now starting to become the norm with 2.5 (3) slot becoming normal on the higher end cards, with even bigger cards being released on the way. And even professional cards are starting to come in at x2 slots.

This basically means that whilst having multiple PCIe slots open (as well as m.2 slots) would potentially be useful for various expansion options further down the road, if those (PCIe) slots are covered up by the GPU cooler, it doesn't really matter how many more PCIe slots you have on the motherboard since you won't be able to use it.

In cases like that, on board (in built) features on the motherboard may be of importance. So if you happen to be thinking of going 10gb ethernet (soon) down the road, the second PCIe 5 x16 slot (going at whatever speed) may actually end up never being used. And you will need the third PCIe slot (which is also shared with an m.2 slot in most cases), which may scupper the use of PCIe slot devices that do need it (like Streaming capture cards, etc). In instances like that, looking at the X670 vs B650 motherboards, you'll see that there's no 10g options (or USB4/Thunderbolt) options for the B650, but there is on the X670. So some pre-planning on that aspect may need to be performed as well to see if it really is better to go with B650 vs X670 boards.

First of all thanks everyone for replaying I will read all this in the morning after a strong cup of coffee and reply with any other questions.

Monk you are right, card coolers are getting larger and louder and i have a hunch in a few years they will go the way of water cooled in much the same way as we have AIO's for CPU's now. You would buy the card and fit the AIO water cooler on it. i recon its the only way forward for the industry or we will have a cooler the size of the case itself.

Currently looks like the X670E-F is £399 and the B650E-E is £364. Not much difference!

I don’t get these overlapping ranges at all. Your broadly getting a similar experience with both of these boards except you have more usb, better bandwidth and better VRMs on the x670e-f but you can get two PCIE 5.0 GPUs on the b650e-e.

I don't get the pricing either between them. I just hate the pricing in general. I mean I paid 141 quid for my B550-F. That was 14 months ago now, and that chipset is now coming up to 3 years old in June ish. 364, 399 quid (and upwards) is crazy. I guess that's what happens when you want new 6 month old tech.

 

[DC2K]

I have a x670e and went with it mainly because it has pcie 5.0 as this will save me having to do another upgrade later on. That was the main reason I bought it.

Not all the x670e boards have the same connectivity though, for example my one has USB 4.0, while others have thunderbolt. I thought to mention because I wasn’t aware of this when I made the purchase.

As for phases, all these motherboards will be more than adequate. The quality of the phases can vary, and I don’t know if this will make much difference.

 

[PaulW]

someone on another site was saying that the X670E-F board does not have the 25100 M.2 sockets that the new gigabyte Mobos have. can anyone tell what the advantage 25100 M.2 sockets would be to have over the Gen 5 ones on the X670E-F i am not that uptodate on this.

 

[Muzzza]

I already have 3x nvme drives so looking at a board that can do 4x. Not a fan of add in cards. Otherwise look at cost. (I'm still grumpy the master x670 dropped the extra 1gb ethernet over the x570.
