Similar thing has happened in GPUs. It started with $1000 Titan GPUs and now the consumer flagship is $2000 and people are still buying which goes to show that where there is a need, the price is mostly irrelevant.
Any many of them are pairing that $2000 GPU with an 8 core CPU, since they don’t need max MT performance. So since they are price insensitive, you could argue the lower core count CPUs is where there is less need for low prices. The gamers will buy them anyway.

Then why did AMD drop the price of the 7950X the most of all the Zen4 DT variants soon after release?
That was a different case. The entire platform price (CPU+mobo+DDR5) was too high at that time. Existing AM5 owners only need to pay for the CPU and even those switching from LGA1700 won't find the price that high, considering there is nothing else they can spend their money on to get the best performance. Some will wait for Arrow Lake. But once that launches and fails to impress, they will possibly move to AM5 too if they are gamers or serious multicore users.

Does not hold as argument for why higher core count DT CPUs should be less price sensetive.

It was the lowest core count variants where the AM5 platform cost made the biggest impact as percentage of total computer price. Yet they cut the price the most on the highest core count Zen4 variants.

Discrete GPUs cover the desktop requirement.
For desktop PC with GPU, yes. But many desktop PCs are relying on iGPU which is not sufficient for the 40+ TOPS AI PC requirements. E.g. typically office desktop PCs do not have dedicated GPU.

Anyway, the original question was whether AI PCs apply to desktop PCs as well. Seems we agree on that it does. Then it’s just a matter of how the AI PC requirements will be met on desktop, i.e whether through GPU, NPU, or some dedicated or regular CPU instructions.

No. The AI PC requirements set by MS applies to all Windows PCs.

The Windows AI features will be used on both desktop and laptop.
it's a laptop thing why are you arguing with me jesus christ.

typical office is a laptop.

Why would 32 thread CPUs be any difference in this regard. You might as well say the same for the lower core count variants.

With Zen4 it didn’t take more than a few weeks after release until there were serious price cuts across the complete CPU range. The higher core count variants saw the highest price cuts.
Zen 4 competed in price/perf with Zen 3. That's all.
On top of being on roughly the same perf/price, Z4 required new motherboards for everyone and expensive new DDR5. It was not worth it.
Nothing about it made Z4 bad, but it was ill competing for some time, and as DDR 5 prices went down, everything got in place.

This has absolutely no relationship with a monster Z5 that'll do more than 40% more ST performance than its competition and will probably be far above ARL when it comes out too.
Then why did AMD drop the price of the 7950X the most of all the Zen4 DT variants soon after release?

Reason is of course that Zen DT is targetting price sensitive consumers. For max MT perf in business use, AMD EPYC is what will be bought. But that is a completely different CPU segment.
Because for all the absurd wattage of it RPL was still performance competitive with Z4. That's literally it. You don't price based on what you want, you price based on what the market will buy.
It's economics 101.

Anyone willing to spend more than $500 on a CPU either has too much money to spare or their work depends a lot on having the fastest CPU available to save them time. Both types of people won't care about the $999 price tag as long as they can afford it. In the absence of competition, they will consider the extra money as well spent.

Similar thing has happened in GPUs. It started with $1000 Titan GPUs and now the consumer flagship is $2000 and people are still buying which goes to show that where there is a need, the price is mostly irrelevant. Geforce 4090 is CPU limited even at 4K. For starters, it is very possible that all Geforce 4090 owners will spend $999 to get the full potential out of their $2000 GPU. They will consider it as a necessary expense.
Nobody, who benefits that much from faster CPU for work that he does not care about money, is going to buy 9950x over Threadripper. Its people on budget who are going to buy that CPU for work, exactly because they cant justify shelling 1500 minimum for TR. So no, most of these people would not be running to get 9950x for 1000.

Cant really compare CPU and GPU situation. Nvidia pretty much doubled their compute performance in both Ampere and Lovelace gen. While their price gouging sucks, they at least provide significant performance jumps to sort of justify it. Pretty sure that 4090 at 1800 nowadays is significantly more performant compared to that first Titan, than 7950x is compared to whatever 600 usd cpu was back in 2013 (5930k?)

Interestingly, I wonder if AMD isn't just going to kill TR.
It's not that successful a platform in terms of absolute sales. There's been more than one report of "bad threadripper motherboards" with no BIOS updates because nobody buys and nobody wants to bother maintaining them.
I've had returns from a lot of TR buyers about how they buy for the PCIe lanes but don't care for the extra cores.

I'm not saying it's dead, I'm saying it's 95% dead in terms of actual market. It meant a lot more during Z1 when the number of cores wasn't enough, but 16 is a lot already and if you need more, for a ton of people, distant servers/EPYC will do the job.
I'm thinking that if you could get 30/40 extra PCIe lanes on AM5, TR would die for good.

It’s not even the UI team. Cloud team as well. I mean I don’t blame them, they are solid laptops.
That's another thing about "Wintel". Typical duo of mediocre software and hardware.

You know you are a flop and a has-been when the company that popularized icons(yea yea others came with it first, but volume matters) with Windows decided to abandon it for their "mobile OS" when Android/iOS expanded on that concept.

In the Windows 95 Plus! edition that I had, you could enable a single click icon mode called Internet mode or something. They could have done that instead. A very refined version of that is what the Android/iOS UI are.

They went with MASSIVE tiles, which took up huge amount of space for a single icon which are meant for small screens. Microsoft Windows team has monkeys as UI designers led by llamas as managers.

The 5930K launched late 2014, that would put it close to Titan X in early 2015. According to TPU perf charts, the 4090 is 5 times faster than the Titan X. Using the same ballpark system, 7950X is almost 3x faster than i5 10400. Factor in the clock advantage and some IPC improvements, and we're probably reaching 4x perf advantage over 5930K.

So, if 4090 is 5x faster for 80% more dollars, then the 7950x can be 4x faster for ~60% more dollars. The CPU should have launched for $960. /s

Not accounting for the fact that a general purpose CPU's 1% gain is far more worth it than 1% on a GPU.

30% gain on games goes from 30 to 40 fps, meaning better playability. 30% gain on CPU is huge.
