AMD Supposedly Resuscitates "Discontinued" B650 Chipset, Motivated by DIY Cost Fluctuations

Around late summer, rumors emerged about AMD leadership notifying its motherboard manufacturing partners about an upcoming discontinuation of the venerable B650 chipset. At the time, alleged "clearance plans" targeted an October 2025 end window—clearing the way for B850 dominance. The two generations have overlapped, in terms of availability at retail, but Team Red seemingly wanted to elevate the newer design's standing. Fast-forward to late November, with conflicting information turning up on the Chinese Board Channels. A short report described a new lease of life for the mid-range-focused AM5 platform: "AMD has confirmed that the B650 chipset will not be discontinued and that motherboard manufacturers will continue to purchase it. The B650 and B850 series will continue to complement each other to meet customer demand."

Despite the more advanced B850 platform offering fancier features, a segment of budget-conscious PC builders have not bothered following the upgrade path to newer board chipsets. After all, three-year-old B650 tech offers support for the latest Ryzen processors. The Board Channel insider article posits that current market fluctuations have influenced Team Red's older product strategies: "considering the significant increase in memory prices and the resulting impact on demand, major motherboard manufacturers are considering adjusting their purchasing and mass production plans for AMD chipsets, particularly for the B650 product line. Factories may increase their purchases of AMD B650 chipsets and initiate additional contract manufacturing capacity."

Makes no sence - what does DDR5 price hikes have to do with this???

Other than markings on the PROM21 chip, are there any actual physical differences at all, between B650 and B850?

My first thought, also.
-then, I realized that w/ increased RAM pricing, there's less room in a budget; a $10-25 cheaper 'older' board, might be an easier sell.

Well my latest build ended up with a 870e board because it was just 300dkr more than the B850 version

-and my X870 'Pro' board was notably less money than my B850 'MPOWER' board.
B850->X870, isn't much of a jump in baseline features; USB4 is the only 'real' difference (and, kind of a net loss vs. a second Gen5x4 M.2 on some B850s).


It looks like the 'B650' iteration of PROM21 is still 'market-attractive' for AIBs since, it supports OCing and Gen5 M.2 but not Gen5 on the GPU slot.
'By the labeling' someone retaining an RTX 3-4000, RX5-7000, etc. card might not see the value in a B850 full-Gen5 board.

It's still an important 'filler SKU' between B840 and B850. Lacking the Gen5 req. on the X16 slot, eases PCB costs.
Meaning, "B650" boards are likely higher profit margin and/or much-tighter BOM.

Must be getting pretty desperate. The fact is virtually all use cases are fine on AM4, with cheaper ddr4. Second hand it's still not too insanely priced.

There are virtually zero actual use cases that need more than 5950x or even it's predecessor.

Not to mention boot time issues and using 4 stick problems on am5.

mb194dccheaper ddr4.
Last I checked it's actually more expensive than DDR5.

EDIT: I need to read, you mean second hand.

Translation: YOU dont need more then a 5950x, therefore faster stuff has no reason to exist.

The rest of the market disagrees with you.

PROM21 on the B650 does support the x16 PCIe slot for a GPU at Gen 5 (even with the primary NVMe at Gen 5 too) electrically. The chip is exactly the same on a physical level, it's just software/board design/maybe AMD restricted. Anandtech (RIP) did a really good article on how little the change was from 600 to 800 series, sadly lost to the ether... but Techspot does have a smiliar (though not as in depth) article on the chipsets.

I've got a B650 board that I can confirm has PCIe gen 5.0 PEG and 2 PCIe gen 5.0 M.2 slots aswell; so it would seem it is up to the motherboard OEMs to implement gen 5.0 or not.

Because budgets of many people haven't risen to account for increase in RAM prices, or the trend in SSD prices.
Hence many of those people might not buy new PC/upgrade at all, if they can't trim costs in some other parts.

What use cases need more?, its a tiny part of the market. Most people are totally clueless unfortunately. Server applications scale in parallel, so do a few tasks like encoding. Very few use cases do them hours a day where you'll notice a big time saving.

More so when you think, you can save seconds on encoding, compiling or whatever. But you lose even more, because Windows 11 takes 2 seconds to open explorer windows and boot takes 5 minutes...

This didnt use to be the case, there were actually big generational changes in the past. Especially Windows 2000, core in 2006 and Zen in 2017.

Now they just make much worse software, like UE5 based games to try and justify the hardware.

Ill get your point. But lets say that you buy a 800dkr motherboard and then use 4000dkr for 32gb memory - thats hard to justify. I would almost rather recommend a bether mother board for e.g. 1800 dkr. and one stick og memory. Beacuse you tend to get stuck with the motherboard

Sounds like your AM4 system is slow. Mine are pretty quick.

Imagine your 5950X working, its humming along nicely.

Imagine your 5950X doing everything faster, and you have your answer.

Anywhoo.. bringing B650 back huh.. pff whatever lol like it really matters.

It truly doesn't make much sense. I thought that realistically they were the same chipset already? Both use DDR5 anyway, so we are talking about a very minimal cost savings.

My previous ryzen 5800x on MSI B550 was nearly same as fast as my current Ryzen 7600x on X670, now X670e motherboard. Note 8 cores are similar as fast for comiling task and gaming workloads as a cheap, entry cpu from may 2023 6-core Ryzen 7600x.

AM5 wins on the motherboard side quite often.

Note: Boot times are not an issue for two DIMMs in use. 4 Dimms are a different topic regarding memory training. For sample size, 1x ASUS motherboard X670 and 1x MSI motherboard X670E

I wonder if the claim that AMD only sells a license for the same ASMEDIA chipset is true. This was posted a few hours ago in the PCGH forum. Most AMD motherboard chipset share the same silicion but have different chipset numbers. When I understood correctly a B650 has a cheaper license fee from AMD. Note: Rumour!

Need and want in a consumer setting at this performance segment I think are interchangeable. The fact simply is that a few % extra perf on a newer CPU isn't going to make or break any use case whatsoever in MSDT.

Since AM5 doesn't need a chipset at all, why not just get rid of it all together? The loss of Sata and USB 2 ports won't be missed much by many users such as myself.
But the price of DDR5 has jumped so much that it won't matter. I was thinking of buying 64GB for 175 euros, now it costs three times as much. A $17 discount on the chipset won't help even remotely.
