Most projects are indeed having a total cost of around $1M for such chips,
including programming and design and package design for

That must be something not sold in a shop then, but something intended to
cream off the university world. Those universities waste money by the
so for them $10k is affordable handsdown.
However for products and cards that you want to sell to ordinary people who
simply want a bit better card, a price of $10k is too much.

No no. 1000-5000.
For 20000+ you can get the entire product including packaging down to way
This card has however 2 chips, not 1. That's a huge difference, additionally
it clocks perhaps
"only" at 250Mhz, but it might be more complex technology than the chip we
wanted to produce.
We just wanted a single giant chip, also at a comparable, though bit higher
Mhz range. Mhz range is however
less important than product price.
Of course for this product if it would be a success, there would be printed
more of them, which probably
reduced the price of the manufacturers offering.
Succesful products, such as chesscomputers, when they do well and are
succesful, you sell around 100000 of them.
That's only for the *succesful* products.
Usually such numbers are only for low priced items, like 99.95 euro
For small amount of products it was not possible to get production price
under $150 however (excluding packaging and
delivery, just card+chip), which meant simply the entire product was not
possible to produce as the chip wouldn't carry any RAM which meant a PC
would outperform it and in general a product sells for 4x more. So that
would mean a bruto price of 600 dollar.
Or a netto price for the customer (add roughly 20% VAT for europe at
products) == 600 euro.
Now of course dollar will go down bigtime, which means effectively the sales
price could perhaps become 499 euro,
which is a very competative price.
Yet you'll have to have RAM on the card then to compete.
It's easy to sell a lot of products if a product outperforms all software
that is out there. Asking 1000-1500 euro a product is possible in that case,
if it doesn't, then a price of 500-1000.
So for example if i put my chessprogram in hardware, that's nearly
impossible, as it's too big (what i write in a few hundreds of lines of C
code in hardware goes default even very well optimized to like 50000
transistors, and the code is 2.2MB in total)
and software is more efficient than hardware, because in software you can
use all kind of caches which in hardware are either
too slow to access, or too expensive to make.
Another alternative is a real chesscomputer from wood with real pieces and
inside it a chip, that's of course interesting.
Alternative is a pci card with a single chip. That's cheaper. But it's 150
euro, 150 dollar without salestax.
The problem is, that software at a k8 just completely outperforms such a

A good chesscomputer gets 100k handsdown.
True, in past they sold even more, and it's dissappearing slowly, as no one
wants to invest in such
Please note that there never was any chipproducer involved. Usually they put
single chips in the
chesscomputers of like 30Mhz and a SH7000 chip or so.
That's real real cheap. That's why they do not sell anymore of course. PC
software and hardware has won
from the own designs.

If you want to earn back your development costs with 1 client,
then you better stop producing such a product.
Only money wasting governments want to pay that much.
