"Currently, ARM processors lack a foothold on the desktop and server. But the company's next-generation Cortex-A15 chip is certainly a step in that direction. Although still essentially a 32-bit design, the A15 adds double-precision floating point support, a 128-bit SIMD engine (NEON), a 1 TB address reach, ECC on cache, virtualization support, as well as much better performance than the current Cortex-A9 generation. The design allows for a 4-way SMP cache-coherent processor, with the possibility for up to 8 cores (or perhaps even 16 cores) to be supported using the CoreLink CCI-400 interconnect. The first A15 products are expected to be delivered sometime in 2012."
I didn't know that ARM was that far behind.
It looks like they are putting in a lot of effort to copy x86 features.
