Sun announces Niagara2 with nice Performance numbers
By vtatkar on Aug 07, 2007
Sun today announced its latest UltraSPARC T2 processor. Sun is calling it the first "system on a chip", meaning it has a lot of features integrated into it that you would normally associated with a system, like computing, networking, security, and input/output. It will be available in a single-socket rackmount or blade server, and is targetted primarily towards TELCO, WiMAX and Network infrastructure deployments
From my perspective, it has some other really nice features that the previous generation Niagara didnt have:
- 1 FP unit per core, 8 FP units per chip
- 1 Crypto unit per core, 8 per chip with 10 dedicated functions supported in HW
- 8 threads / core (twice of Niagara), 64 threads /chip which gave
it the highest SPEC OMP2001 numbers for a single chip
- Highest SPECintrate 2006 and SPECfprate 2006 numbers for a single
chip easily outranking every other chip
How competitive are these numbers? Check out these two blogs from Sun's BMSeer describing this chip and its comparison with Intel/Clovertown, AMD/Opteron and IBM/Power chips: the first blog compares SPECint and SPECfp rates on a single chip, the second blog compares SPEComp numbers.
Its a nice chip, overall, overcoming many of the common deficiencies of the earlier, but still very popular Niagara chip. I hope Sun does very well with it; it does have a lot of potential.
Of course, all reported numbers were generated with Sun Studio 12 compilers.
All SPEC CPU metrics quoted are from full "reportable" runs, but are designated as "estimates" because they used pre-production systems. SPEC, SPECint, SPECfp reg tm of Standard Performance Evaluation Corporation.
