B650m and 9800x3d

[Jade]

Would b650m am5 mobo support 9800x3d?

Intel doesn't even use TDP anymore, it got replaced with Processor Base Power (PBP) which would be 65W, 125W, etc. and Max Boost Power (MBP) which would be where 235W+ comes into play for stuff like the i9s

AMD also uses PPT
„PPT is a measure of the total power consumption of the entire CPU package, including cores, cache, and uncore components.”
7800x3D has PPT of 162W while having some of the lowest real life power consumption. About 30-60W when gaming.

PPT is the maximum it can use, not what it actually will use, it's not often that they're pushed to that which is usually in a heavy all-core load

Their 65W TDP chips have a PPT of 88 but chips more often than not ran closer to 65W funnily enough.

Depends on the board, there are plenty of B650 series boards that could handle it but if you pick a bottom end motherboard model, you might not get the full performance out of it.

Yea it's not like Intel where the B chipset boards are all limited features and total crap for the most part.

Most b650 boards seem to be rather decent.
According to Hardware Unboxed only three of them struggle with 16 cores CPU but that shouldn't be a problem with 8 cores CPU.

I think B650m from Asrock look especially good for the price.

Yes you absolutely would never want any B650 board for any Ryzen 9 CPU

But yea for Ryzen 5 or 7 I don't see the issue as long as the board is not totally bottom of the barrel cheap junk

This.

I'm not sure why some others think the Xx70 boards are needed for gaming. This isn't like the Intel platforms of 5 to 10 years ago where you usually did want the top chipset to get the most out of the K variant CPU, or to use RAM profile speeds to their fullest, and so on. The big thing the AMD Xx70 boards offer is more PCI Express bandwidth for multiple SSDs at one time... and yeah, that's not needed for gaming.

Many of the B550 boards were actually comparable or even a bit better than the X570 boards too.

With B650, I think many of the earlier/first generation boards were good, but many of the second wave ones were actually pretty mediocre? I'm recalling a Hardware Unboxed video on them when updated ones released and I recall many of them weren't that good.

i guess you missed the fact that spending money on a 650 board that would support a 9800x3d would put you in a price range of the middle ground 670 boards.....but me building 15 rigs in the last 90 days would give me this clue.....if you want to spend 300 bucks on a 650 board when you can have a better 670 board for 220ish that is up to you......

In what sense better?
More USB ports? Because gaming performance will be the same.

I didn't even make a particular suggestion so I'm not sure how you think I'm overlooking things.

I was only stating that the Xx70 chipsets typically bring features that aren't always necessary for a user of a gaming PC, so the suggestion that one "should" use them for that CPU seemed unusual to me.

If you're making a statement that they should be chosen for price reasons, then just say so. You made it out like the chipset is why it should be used (since you stated only that factor, and gave no additional context), so I merely responded to say the chipset may not always be necessary.

Though, yeah, I guess you could say I am missing something because now I'm confused; why you would need to spend more for a B650 board than an X670 board that supports a 9800X3D? BIOS updates tend to add CPU support for relevant boards. Unless you're making a statement that every B650 board below $300 is not even worth using at all, or will never get support for the 9800X3D, then I'm not sure what your angle is with that statement.

B350 - mix of mid and outright cheap (in a bad way) motherboards with issues
B450 - mostly mid, some bad, basically none that were really good
B550 - mostly decent, some mid, some really good, a few unnecessarily good
B650 - some good, some decent, some mid, probably some bad

Its the generation man, 300 series is older than 400 series and so on. 'A' means cheap boards like A300 or A310, and X means the good stuff, like X370, pretty much like processors, B is average/good boards

There you can see diferences between chipsets.

am5 chipsets, basically the 600/800 series.

he was talking about the average quality of the bx50 boards
of course the older chipsets are older, but the average quality has gone up slightly since the newer cpus are more power demanding
