World Record Single-Chip UltraSPARC T2 SPECint_rate2006 Performance with gccfss

Thursday Feb 14, 2008

World's fastest chip. The Sun SPARC Enterprise T5120 server, running at 1.4 GHz, delivered a world record single chip result of 83.9 SPECint_rate2006. Please remember it is about system performance and chips not about things inside a chip (like perf/transistor, perf/NAND-gate, perf/metal-layers, perf/thread, perf/bore, oopps perf/core, perf/silicon grain).

The Sun SPARC Enterprise T5120 using the GCC for SPARC Systems (gccfss) compiler topped all competitor's single-chip results including beating the IBM p570 single-chip 4.7GHZ POWER6 result by 38%. IBM used its proprietary compiler, XL C/C++.

The Sun SPARC Enterprise T5120 using the GCC for SPARC Systems (gccfss) compiler beat the performance of the HP DL360 G5 with a single chip quad-core 3.16GHz Xeon X5460 by 15%.

The gccfss compiler allows one to use the optimal Sun SPARC optimization tools along with the popular gcc coding conventions and deliver performance that has not been possible before without time consuming code changes.

Sun also submitted results on the SPECfp_rate2006 benchmark suite using just a single disk. The Sun SPARC Enterprise T5120 server, running at 1.4 GHz, delivered a result of 62.1 SPECint_rate2006.

This result was run on a single disk. The previously reported result used the electrical equivalence rule of SPEC, but the configuration used more disks than fit in a T5120. This result shows that the performance is comparable, regardless of the disk configuration.

Benchmark Description

SPEC CPU2006 is SPEC's most popular benchmark. It measures:

The strategic metrics include:

There are "base" variants of both the above metrics that require more conservative compilation, such as using the same flags for all benchmarks.
