Congratulations to the SPARC M7 team for delivery of a monster computer chip incorporating 32 cores, each of which
simultaneously executes 8 independent threads, for a total of 256 CPUs on a single chip.
67% more integer throughput than the nearest competitor
76% more floating point throughput than the nearest competitor
The above comparisons are based on best single-chip SPECrate results, as posted at www.spec.org through today, 26-Oct-2015.
What about POWER8?.... Well, there aren't any 1-chip results at spec.org... now what?
Yes, it is correct that IBM has not submitted results to the SPEC website for systems using only a single POWER8 chip.
Interestingly, though, the newly announced SPARC T7-1 system, using one SPARC M7 chip, outperforms two
IBM POWER8 chips on three out of four top-level metrics:
2-chip POWER8 SPECrate results
1-chip SPARC M7
|CPU Name||POWER8||SPARC M7|
|Number of Chips||2||1|
|Number of Cores||20||32|
|Number of CPUs(*)||160||256|

"hardware threads", "threads",
"virtual processors", "logical processors", "processors", "virtual CPUs", and so forth. From the point of view of the operating
system, there are 256 independently scheduled CPUs available on a single SPARC M7 chip.
Congratulations are due to all who work to deliver stunning throughput, including but not limited to the chip group,
Solaris, Solaris Studio, and in particular to the performance lab rat who puts it all together in a well-documented,
reportable performance result.
