1  Bitcoin / Development & Technical Discussion / GPU to hash metrics on: January 19, 2011, 07:43:09 PM
Are the number of Stream Processors the most effective specification to directly relate a specific GPU to hash/s metrics?

For instance:

My ATI "Redwood" has 400 stream processors and can push about 36,000 khash/s.  (@90 khash/s per stream)

An ATI HD 5970 can put out 560,000 khash/s with 3,200 stream processors (@175 khash/s per stream)

My NVidia Quadra NVS 135M has 8 stream processors (hahah!) and does 950 khash/s  (@~120 khash/s per stream)

Other metrics don't seem to matter that much, i.e. GPU memory and memory speed, GPU clock speed, bus width, etc.
2  Economy / Trading Discussion / Exchange Market *Special* Report 29 July on: July 29, 2010, 11:25:38 PM
Today we witnessed a major shift in the two BTC exchange markets.  Bids now outweigh Asks by a margin of about 3 to 1 on GOX (Ask Volume: 3686.57  Bid Volume: 9420.01), and a quick glance at the offers tables at the BCM show many more bids than asks.  It's pretty clear that exchange prices are rising after a slump at the beginning of the week.
3  Economy / Trading Discussion / Exchange Market Report 25 July on: July 25, 2010, 03:44:42 PM
The end of the week saw a sharp decline in exchange prices from earlier in the week.  Both markets, Mt. Gox 24/7 Bitcoin Exchange (GOX), and the original Bitcoin Market (BCM) showed steep price drops (~-40%) with high Exchange rates from 0.087 - 0.093 USD/BTC down to 0.054 - 0.059 USD/BTC.

Based on historical prices from early July, the BC exchange rates have shown roughly a 10-fold increase in BTC market valuation (0.005 to 0.05).

Recent Bitcoin generation woes with the Pitock hubbub, and the recent Slashdotting of Bitcoin have led to high proof of work difficulties, and are the likely causes of the recent price bubble.

Ask to Bid volume ratios on GOX are currently running nearly 3 to 1 (Ask Volume: 9026.99  Bid Volume: 2893), down from a speculative high of about 4 to 1 on Saturday, and show the markets' need for BTC spending outlets.

The Bitcoin crypto-currency system has recently surpassed the 70,000 block milestone, leaving 3,500,000 potential BTC in existence with a current valuation of about $200,000 (USD).
4  Other / Off-topic / I want a Progress Quest Bitcoin Client on: July 20, 2010, 01:23:58 AM
I can envision a pleasant marriage between Progress Quest and the bitcoin client.  (

I always check it like a junkie to see if I've generated a block.  Why not have something interesting to look at when I open the client?
5  Economy / Marketplace / Selling Zynga Poker Cash for Bitcoins on: July 15, 2010, 01:31:53 AM
Zynga sells coins at the discounted rate of 30,000,000 per $75.

I will sell my stash at the generous rate of 20,000 chips per BTC.

That's 1 million chips for a dollars worth of BTC!

Send me a message and we'll make arrangements.
