AMD B850 and B840 chipsets are delayed, might debut in early 2025

In brief: As manufacturers exhibit next-generation motherboards at Gamescom 2024, the roadmap for AMD's upcoming 800-series chipset is becoming clear. Ryzen 9000 early adopters will likely have to use the new CPUs with 600-series boards for now or wait a while and splurge on the newest high-end X800 models later this year.

After interviewing motherboard manufacturers at Gamescom 2024, ComputerBase reports that AMD's next lineup of mid-range chipsets likely won't begin shipping until next year. B850 and B840 models might appear at CES 2025.

Vendors such as Asus have prepared Gamescom showcases for new flagship X870 and X870E motherboards, which are expected to arrive in September. Full specifications for Asus' ROG Crosshair, ROG Strix, TUF Gaming, ProArt, and Prime variants are now available.

The cheaper B850 and B840 are largely absent from the event, indicating they are scheduled to launch at a later date. The X800 and B800 tiers are designed for AMD's recently released Zen 5 Ryzen 9000 desktop CPUs. However, customers wishing to upgrade to the new processors can also use older 600-series motherboards since they support the same AM5 socket, though they might require BIOS firmware updates.

Upgrading from X600 to X800 offers a few notable advantages. All X870 motherboards will support 40Gbps USB 4.0 connections. Furthermore, users gain simultaneous access to PCIe 5 lanes for NVMe SSDs and dedicated graphics cards without spending extra money on the extreme model.

GPUs supporting PCIe 5.0 haven't appeared yet, but upcoming lineups like AMD's RDNA4, Nvidia's RTX 5000 Blackwell, and Intel's Battlemage are expected to support the feature. The latest information indicates that the three manufacturers will debut their next-generation GPUs in late 2024 or early 2025, possibly alongside AMD's more affordable B800 motherboard chipset.

Some B850 products might include enough PCIe 5.0 lanes for SSDs and graphics cards, but many will relegate GPUs to PCIe 4.0 like most currently available motherboards. Furthermore, the B850 only mandates USB support up to 20Gbps 3.2 connections. Meanwhile, B840 only requires PCIe 3.0 lanes and 10Gbps USB 3.2 ports, suggesting that it might be a successor to the ultra-budget A620. Users shopping for mid-range AM5 boards next year should carefully compare specs for B800 and B600 offerings, as their differences aren't dramatic.

Given the problems with AMDs latest offerings, I can imagine many holding off to let others test the water and wait the 9000 3D chip as well. A Flakey system is a flakey system .
Won't be surprised if AMD tweaks the profiles etc
With Intels mess up , AMD didn't need to rush to market. If I wanted a productivity workhorse in the 9950x , I'll want a X870 board to give me as much bandwidth and data speed as possible.

Intel in the 2010s gave you compelling reasons not to upgrade small YOY increases for stupid prices

Now CPUs are so good, most people game at 2060p or 1440p, so GPU is main upgrade for gaming. Plus people more likely to build/buy a NUC, handheld, tablet to meet other needs with that rapid advancement

I can't see a reason now to upgrade less than 5 year gaps, except you just want to , so why rush. People would complain if PS6 .PS7 came out every 3 years
