I'm testing out a new server with a Xeon 6130 CPU and trying to compare it to an older box with the E5-2660v4. Here's a test I just ran on each box:
On the 6130:

The Skylake CPU scored 68k bogo ops/s. The older Broadwell CPU scored ~100k bogo ops/s. Is it fair to compare these values across CPUs? And the 6130 has roughly 2/3 the L3 cache of the E5-2660v4. Is that why it scores ~70% of the 2660v4?

Best Answer
In short: no.
All else being equal, you should get better numbers for a newer, more power hungry processor with more cores (the 6130). For reference, in PassMark, the Xeon E5-2660 v4 gets 17786 points while the Xeon 6130 Gold gets 20222 points as seen here: https://www.cpubenchmark.net/compare/Intel-Xeon-E5-2660-v4-vs-Intel-Xeon-Gold-6130/2881vs3126.
You should never trust other benchmarks; Instead, you should create your own set of benchmarks to compare hardware configurations with real world situations, as I doubt you use these to perform stress tests all day.
