Calxeda (previously known as Smooth-Stone)[1] is a start-up company that aims to provide ARM-based computers for the server market. Their selling point is a claimed reduction in energy consumption as well as better cost per throughput, compared to x86-based server manufacturers such as Intel. Currently a 480-core server is in development, consisting of 120 quad-core ARM Cortex-A9 CPUs.[2][3][4]
Calxeda will compete in the many-core server market against current server market leaders Intel and AMD, other recent ARM-based server vendors such as Marvell (Armada XP), and the massive multicore CPU manufacturer Tilera.[5][6]
The current Calxeda product offerings include the EngergyCore ECX-1000 SoC, featuring four ARMv7 Coretex-A9 cores operating at 1.1 - 1.4GHz, 32KB L1 I-cache and 32KB L1 D-cache per core, 4MB shared L2 cache, on-chip fabric switch, 1.5W per processor, 5W per server node including 4GB of DDR3 DRAM, 0.5W when idle.[7]
