By taking another step on Moore’s Law, using a low-voltage processor and changing to 10 gBE NICs, Intel was able to stay competitive with Calxeda in throughput per watt… proving what we knew all along, that ARM has a place in the server room:
“Without the overhead of the power supply (which only runs at 90 per cent efficiency or so), the fans in the chassis to keep the node cool, and the disk drive, the EXC-1000 microserver did 5,500 requests per second at 5.26 watts measured at the wall, which works out to 1,046 requests per second, per watt. That’s about 40 per cent better performance per watt against the Xeon E3 v2 with a 10GE port and about five times better than the Xeon E3 v2 with only a Gigabit Ethernet port. But this comparison is still not exactly fair, says Hill.”
Move over Intel, ARM is invading your spaces this year.
