AMD Reportedly Discontinues B650 Motherboard Chipset, Insider Predicts Q3'25 Stock Depletion

Just checked on Newegg and there is still plenty stock of B650 and even B650E.

If it's something that's happening in the "channel", it's not gonna become apparent in the consumer-facing retail market until a few months later.

As long as they don't discontinue the b650e chipset, no b850 mobos feature cpu lanes splitting, it's ok.
Since we don't need 16 pci-ex lanes for the gpu anymore, having an additional x8 gen5 slot on a more affordable mobo than the high-end solutions, is a great feature. I'm talking about the Asus b650e-e strix.

Do tell...

Yeah

I would say that by the time something is released that saturates even pcie 4.0 x8 lane, the cpu will be obsolete and a bottleneck for said GPU. Especially since a 5090 isn't starved of bandwidth on that.

*when the graphic card has enough VRAM, bigger as 16GiB.
*when the game itself and the drivers are optimised
*when the gpu chip is not made worse

I suspect there will be scenarios with memory starved graphic card where the bus will be used a lot. I assume proper drivers. The big indiactor is that a graphic card needs more than one pcie lane.
pcie 5.0 is old tech. pcie 7.0 is already out or near specification.

I think you misinterpreted some analysis/reviews about performance scaling on mem starved gpus.
A card with insufficient VRAM performs EVEN worse on a smaller pci-ex bus (bandwidth starved) which doesn't mean it works as intended on 16 lanes. Both on 8 and 16 lanes, the latency introduced by the system memory affects 1% and 0.1% fps, frametime inconsistency, which makes the games unplayable no matter what avg fps you record.

As TPU showed in their test, as of today 4 pci-ex gen5 lanes or 16 pci-ex gen3 lanes are not a limiting factor. So 8 pci-ex gen5 lanes are good enough even in the foreseeable future.
Pci-ex performance scaling is way slower than pci-ex gen updates.

You may check the german hardwareluxx or german computerbase forum. A few hours ago i read a user topic on my tablet, over 300 pages long, only about vram usage in different games.
some will never understand. I even saw videos here. ...
