1) BitForce SC Jalapeno: a USB powered coffee warmer providing 3.5 GH/s, priced at under $149
2) BitForce SC Single: a standalone unit providing roughly 40 GH/s, priced at $1,299
3) BitForce SC Mini Rig: a case & rack mount server providing 1 TH/s, priced at $29,899
This is going to completely decimate the FPGA and GPU industries, if Butterfly Labs is able to keep up with the demand.
*Looks at my poor little 5770 at 220 MH/s, and then at BitForce Jalapeno at 3.5 GH/s at 'approx' same price*
"Aw crap!"
Email specs says 50% increase in hashes. at these nunbers
1) 4.5GH/s
2) 60GH/S
3) 1.5TH/S
MATH is tricky.
4.5/3.5 =
1.285714285714286 (Or
128.5....% of specs listed on Topic initially and order page. Looks less then 50% increase.)
60/40 = 1.5 (woo hoo an actual 50% increase in performance.....)
1.5/1 1.5 (wow This one oddly has 50% more performance too.)
Other math.
3.5*1.5=5.25
Extrapolating I ordered the 8 pack upgrade.
Initial Specifications: 28GH/s
Release Specification: 36GH/s
50% increase Spec: 42GH/s
Amount I am short 42-36=6GH/s
1.33repeating Jalapenos. Lets use some fuzzy BFL math on that and call it 2. Any chance you will ship me a 10 pack and actually give me the % increase stated?
I'm really starting to dislike Bitcointalk because of people like you.
Jalepenos could not be doubled because of the USB buss power limitation. This was already stated by BFL.
Why don't you just convert your 8 pack into an "SC Single", or two "Little Singles"? Bfl has stated that you can upgrade with no change of your place in line.
@Sharky
What did I do that upset you? I pointed out that the EMAIL told me IN WRITING that I would be getting 50% more hashes I am in fact getting less then 30% more hashes. I suppose it is wrong to fact check the news letter before sending it out. Maybe it sounds silly but when somone says 50% more I would expect and additional unit per two units in the initial specificaton. Not one for every 3 or less. Possibly this is bothersome. But it is an inconsistency.
@freeAgent
True but I dislike the noise and if my current single gives me an idea of what may need done to get a functioning unit I would rather have 8 so one can be warrantied at a time then 1 that won't get me enough money to be worth the turn around time. Yes mine works but without a thermal redesign I could only run 2 bitstreams as shipped to me prior to the official releases. the 816 and the 808. <=800 always ran stupid short work units and many GH/s but no found shares, 832 had a bad power listed on easy miner and crashed immediately and everything above 832 with a 68 degree F intake temp throttled excessivly. Granted 864 put down better numbers then 816. I couldn't get 824(not public release) to work and 848 worked but reworking it thermally got 864 running with low throttles.
The jalapeno pack was 70% of the speed of the single initially. I was willing to take that haircut for multiple units, no single point of failure and less noise.
The improved jalapeno pack is 60% ofthe speed.
Another way to put it.
Jalapenos initially where 0.023489932885906 GH/s per dollar.
SC single was initially 0.0307929176289453 GH/s per dollar.
Upgrade Jalapeno is 0.0302013422818792 GH/s per dollar.
SC single upgrade is 0.046189376443418 GH/s per dollar.
EDIT: 832 above should have been 816. Never was able to get 832 running. It isn't like I dislike BFL. I have soo far actually been fairly pleased with their products. That having been stated I would say that my unit was less then spectactular for a 3 fan Rev. 3. Now it is far quieter and only occasionally throttles running 864 with warmer summer temps.
Edit 2: After rethinking my point, I wonder if heat is a limiting factor not power. The only (edit) passivly (edit) aircooled unit got less of a bump. Possibly it is related. The issue to me still is not that the 4.5 is a good enough number but that the % listed was wrong. Yes on 66 2/3% it is correct but if memory serves that will net you a D in most educational situations.
