CPU Yields

Ok so here is a list that I have pulled together from t'internet

This list talks about CPU Yields

What I would like to discuss here is what the true amount of recoverable gold is in CPU's

The "Information" that I have ( this is wide open for debate..... )

VERY HIGH YIELD CPU’S – Have quarter of a gram or more per piece.
HIGH YIELD CPU’S – Have from 1/20th of a gram up to quarter of a gram
LOW YIELD CPU’S – Have under 1/20th of a gram

Very High Yield

Pentium Pro (the holy grail of yields) 1.0g – $46.30 per CPU

Intel Pentium Pro 133MHz 256k * 1.00 gram GOLD

AMD-K5 PR133 0.50 gram GOLD

I would say that the high yield figures are about right, there's a few that are on the hopeful side.

The very high yield figures are not right.
I know you see Pentium Pro's going for a high price but i think that's because of lists like these.
There is approx 0.5g of Gold in a Pro, some of them i only got 0.3g.
The K5's definately do not have 0.5g of Gold in them.

Remember too that these figures are based on TOTAL Gold content.
Many of the earlier cpu's had Gold plated lids, top and bottom.
Also, when you take the bottom lid off, you can see the Silicon chip.
Under this chip is a large portion of the available Gold.

There are some very inflated prices for ceramics cpu's at the moment.
I process most of mine but i can't get any due to the silly prices. :roll:

I bought a Cyrix M11 Plus two Ceramic Intel Pentium Chips on Ebay for 1 penny each two weeks ago.

There are some people who are doing auctions.

I did pay 12 Euro for postage which I thought was high. ( from UK to Ireland )

But Ebay recommended that the postage be signed for otherwise the item probably wouldn't arrive.

The Internet does the opposite of what it promised us all originally.

It is hard to find true figures and facts on many subjects online.

Perhaps that is why forums can sometimes offer enlightenment ....although this can also be a rarity.

But I agree with Buzz, people on eBay seem to think that they can start an Auction at their perceived recovery rate and go upwards from there.

Please do not tell Irish Auctioneers about Gold Recovery ...... :D

Establishing the facts is important as it allows people to trade with confidence.
