Zoomy Is As Zoomy Does
Huh. Well, the numbers don't lie. Probably.

Huh. Well, the numbers don't lie. Probably.
My new servers at ReliableSite in New Jersey - Aoi and Midori - use Xeon E3-1245 v2 chips; the ones at Incero in Dallas - Akane and Mikan - use Xeon E3-1270 v2s. There's only 100MHz between them - 3.4GHz and 3.5GHz respectively; the 1245 has integrated graphics while the 1270 does not, so the 1270 uses slightly less power but needs a video card or a motherboard with integrated graphics.
I have a Xeon E3-1230 as well, the previous generation at 3.2GHz.
The 1270 v2 runs my Python benchmark 15% faster than the 1230 v1, which is ~10% clock speed and 5% architecture. Fine.
The 1245 v2 runs the benchmark 25% faster than the 1230 v1. I checked several times, and it's consistent. Don't know why, but it's consistent. It looks like Incero and ReliableSite are using different motherboards, but that shouldn't make a difference to this benchmark.
It's also in line with the Passmark benchmark results that show the E3 v2 chips competing with the low-end Opteron 6200. They don't have the same memory capacity or bandwidth, and can't scale past a single socket, but they're certainly fast.
And we now have five of them. Well, I broke one, so four right now, but I'll have that fixed tomorrow.
