In a surprisingly technical press release, IBM announced yesterday that the 970FX rocked the TeleBench benchmark from the Embedded Microprocessor Benchmark Consortium (EEMBC, pronounced “embassy”). To be fair, most of the competition is sub-GHz embedded processors, and your editor hasn’t heard of many of them. The 2GHz 970FX approximately doubled the performance of Freescale’s 1.7GHz 7448 (“G4”), but no comparison was made regarding power consumption/heat dissipation or other real-world design factors.

Interestingly, while many of the processors benchmarked (including the 970FX) used Green Hills’ compiler, IBM also enhanced gcc’s autovectorization capabilities and ran with that. The results were huge.
