New 700MHz R16000 MIPS proceccors from SGI

SGI announced its new 700MHz R16000 MIPS processors. Similar to the previous R14000A, new 64-bit 4-way superscalar R16000 feature 32Kb two-way set-associative on-chip instruction cache, 4Mb L2 cache, support MIPS 4 instruction set.

No more details are available about the new CPU. I wonder what is the dissipated power of R16000. As you know, SGI claimed low energy consumption to be one of R1x000 critical aspects. As 0.13-micron R14000A dissipated just 17W at 600MHz, it enabled to install a 128-processor SGI Origin 3900 system in a single rack.

Initially, new R16000 chips will be shipped in SGI Fuel Visual Workstations workstations with VPro 3D graphics and IRIX OS.

According to SGI, the company, similar to Hewlett-Packard with its PA-RISC, plans to move to systems on 64-bit Intel CPUs: its Itanium 2-based SGI Origin systems will work under Linux. Though SGI won´t turn away from its own processors in the near future, at least last summer SGI announced the MIPS roadmap up to 2006.
