Title: Ye olde hardwaree: CPU or GPU? Post by: raw on July 27, 2011, 11:45:00 AM Disregarding efficiency and other concerns right here, I have a box with an AMD Athlon XP+ 1600 @ 1.4 GHz and a NVIDIA GeForce2 MX 100/200. Now, both these components are sufficiently old enough to not show up on any hardware list regarding bitcoin. Where would I mine with these components, the CPU or the GPU?
The CPU makes a whopping 450 khash/s. ;D Title: Re: Ye olde hardwaree: CPU or GPU? Post by: Yeti on July 27, 2011, 11:50:09 AM Not at all?!
If you do not have a dedicated rig and an efficient GPU (read ATI 5xxx or 6xxx series) it's not worth the cost of electricity, noise and heat. If you do, join a pool. You should get hashes 1,000 times that amount, that would give you 0.25 BTC per day in mining. Of course, if you want to do it just for fun / enjoying the technical side of it, go ahead. You might get a couple of Satoshis. ;) Title: Re: Ye olde hardwaree: CPU or GPU?

Your only chance is to CPU mine. You're probably looking at maybe a few hundred kilohash/second, if that. Title: Re: Ye olde hardwaree: CPU or GPU?

Now, motherboards of that generation will have only AGP and PCI slots, no PCI-E. The best video card that is suitable for mining and available in AGP form is a 4650; it can be found on a few websites, cheapest I found is here http://www.geeks.com/details.asp?invtid=HD-465X-ZPF2-R&cat=VCD (actually google shopping has a few hits for 4670 AGP, but they're all over $120 - not worth it IMHO for an extra few Mhash/s) According to https://en.bitcoin.it/wiki/Mining_hardware_comparison you can expect around 30Mhash/s from it, which will make you about 0.015 BTC/day. It's about the same hash rate I get from a geforce 8800GT. (edit) Newegg has an AGP 4670 for $99.99 after rebate if you're so inclined: http://www.newegg.com/Product/Product.aspx?Item=N82E16814161337 (edit2) There are also a few PCI (not PCI-E) 5450 cards at newegg for around $100 a pop, each predicted to give a whopping 15Mhash/s or so. :) Title: Re: Ye olde hardwaree: CPU or GPU? Post by: Dargo on July 27, 2011, 04:17:57 PM If you just want to do this for fun, go for it. But if you want profit, you're going to need a new rig with good card(s) for mining.
