How to calculate Hash rate

[Rogue]

I was wondering if there was a way to calculate the Hash rate of a given card or chip based on the specs like Wattage, MHz, etc..

Is there a formula for it or is the hash rate solely determined by the architecture of the chip/card core?

I was also wondering what the current specs are for an individual Asic chip. (looked every where and couldnt find a spec sheet)

Not exactly what you are looking for but: https://en.bitcoin.it/wiki/Mining_hardware_comparison

BFL ASIC chips: https://products.butterflylabs.com/homepage-subproducts/65nm-asic-bitcoin-mining-chip.html

If I'm remembering properly, individual ASIC chips are rated at:
Butterfly Labs: 4,000 MH/s at a price of ~$75 per.
Avalon: 282-333 MH/s at ~$8 per (at current BTC and average group buy prices).
KnC Miner Jupiter: 5208 MH/s at ~$145.83 per.

If I'm wrong, someone can correct me. That's what I've gathered, though.

From what I gathered, the main thing you'd want to look for when making some sort of equation is "Stream Processors". You can have many cards with the same clock speeds, but the one with the most Stream Processors will outshine the others easily.
I couldn't really find a chart comparing all Radeon/Nvidia stream processor counts. There are plenty for certain families (like this page halfway down), but haven't found one large chart of all of them.

There is a rough calculation of how

For example, found on http://bitcoinwatch.com/
Network Hashrate Terahashs/s    168.34
Network Hashrate PetaFLOPS            2137.89

There is a rough conversation method which is found from (Approximately)

If for no conversation, then You may use

To find out, since there is only 144 blocks a day, then you are able to find the answer.


After the sorting out above, If asking hardware performance, the question will be on 32-bit integer shifts (INT32) issue. Note that the NVIDIA suffers the operation a lot (TITAN) Even optimized, about 66% of The AMD 7970.

If there are more FP32 units, then the performance can be increased
