Most projects are indeed having a total cost of around $1M for such chips,
including programming and design and package design for 
supermarkets/resellers/salesmen/stores.

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 
shitload,
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 
smaller
money.

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 
computers.

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 
hardware chip.

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
products.

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.
