I'd say that pricing and market segment is no more.
There will always be an ultra-low-end market for people who simply want more display outputs than whatever graphics are already present can provide.
The biggest problem with the $150-200 entry-level price range is manufacturers are being greedy, wanting to push their gross profit margins on entry-level GPUs as close to enthusiast margins as possible while providing as little value as possible to force people to take a step up on the price ladder, so we get generation upon generation of either underwhelming entry-level offerings or nothing whatsoever, especially during a component shortage and crypto boom.
The component shortages and crypto boom are mostly over. This should have an interesting effect on next-gen GPU sales and with some luck, AMD and Nvidia will have a renewed interest in competing at the largely untapped and heavily neglected lower-end for sales when their new stuff at likely further inflated MSRPs fails to meet inflated sales expectations from covid and crypto boom.
And cards like the 4550, 5550, and 6450 were praised by TomsHardware during their reviews for their HTPC capabilities, passive nature, and low prices.
I wouldn't use a passively cooled GPU, own one, wouldn't buy another. Kind of pointless when you have to make sure there is a case fan pointed at it to prevent it from running obscenely hot since natural convection keeps hot air trapped around the source in a conventional tower setup.
Also, if you aren't going to use your HTPC for 3D, you can just use the IGP until new CODECs not supported by the IGP and too spicy for software-decode on the CPU come along. That is much cheaper, power-efficient and easier to cool than the cheapest GPU.
