Athlon 64's in Hetzner's Auction - who's renting these?
Having watched Hetzner's server auctions for a while, there's something that never really made much sense to me.
You see the following server configuration show up frequently: AMD Athlon 64 3700+, 2GB RAM, 2x 160-320GB HDD.
What's weird is that they're always priced the same as significantly more powerful i7 systems with 16+GB RAM and 2x2TB drives.
At the time of writing, there's 3x Athlon64 systems listed, all at the currently cheapest auction price of €26.89/mo, but for the same money, you can get a i7 2600/3770/4770, 16-32GB RAM, 2x 2-3TB HDD system.
Ignoring Hetzner's other dedicated servers, a single-core Athlon64 3700+ at that price isn't even that good value, considering that cheaper VPSes probably perform better (or if you need dedicated resources, there's plenty of alternatives with better specs for cheaper).
If it's a price reduction auction, and no-one was renting these Athlon64s out, you'd expect the price to fall lower than the i7s, but I never have seen this happen. This seems to suggest that someone is picking these systems over the i7s, or that Hetzner is recycling them behinds the scenes to prevent the price from going down (I've seen some servers listed as "Fixed price", presumably for that reason).
Assuming the former, why would anyone pick an Athlon64 over the i7s?
