@Plinker Tind.

Yes, companies choose their statements to suit their needs at the time. Oracle does it, IBM does it, they all do. So what?

However, the point the IBM chap was making is actually valid. For business use, you need the chip that provides the greatest benefit for the lowest cost. This benefit could be throughput, functions or whatever. Benchmarks are appallingly bad at representing real life and have been misused by companies since the dawn of time to try and prove different things. On a typical mixed business workload, often highly virtualised, Power 8 performs very well, is extremely flexible and has a great ROI case. Sparc M7 is a good processor. I'm not knocking it. But, if anybody truly believes Oracle has got something an order of magnitude better than anyone else in REAL world use cases, they're deluded. Genuine order of magnitude advances like that are as rare as rocking hose s**t.

In your final comparison as well, you are actually comparing products from different times as well. Sparc M7 was released in 2015, but Power 8 was released in 2013, a whole 2 years earlier, which in processors stakes is a long time. Also, you've got to compare like with like, which you're not. Given that Oracle licence per core, that single M7 cpu has 32, whereas the four Power 8 cpus would have 48 at maximum (can't be bothered to look at the benchmark to check). So, you're factors are way off. You can't ignore the number of cores. Does it matter if the server has a smaller number of sockets and more cores per cpu, or more sockets and fewer cores per cpu?

Finally, if raw power was really so different as you claim, why has Oracle not succeeded in the HPC stakes? You will notice a distinct lack of Sparc based supercomputers. Fujitsu have one, but IBM have many based on the Power architecture. Also, NVLink being built into the processor could well be a game changer for performance, especially in HPC. Have Oracle put anything like that into Sparc?
