Core i7 performs very badly?

0

I would like to know why a core i7 HQ 6700 2.6GHz performs very badly compared to a core i5-4570 3.2GHz. This is the scenario, I'm running a very expensive method to populate a MSSQL DB, the i7 taks (+/-)30min while the i5 (+/-)30sec, I mean the gap is gigantic, I cannot seem to understand why. Also The i7 runs 24Gb DDR4 while the i5 16Gb (probably ddr3). Both use SSDs which are in the same range of performance.

I cannot seem to understand what with this huge performance gap.

2Unless your code is multi-threaded and uses a substantial amount of memory the i5 should be faster than the i7. – Ramhound – 2019-04-01T09:58:34.970

1You might have very differently configured databases or more difference that are not just hardware if the difference is really 30 seconds versus 30 minutes. – Seth – 2019-04-01T10:49:09.163

The i7 HQ is a mobile processor. The official comparison. Both are quad cores, the i7 has HT so it does have, according to your linked benchmark, higher performance on benchmarks that utilize more than 4 cores.

The optimization targets for the i7 are going to be different as it's a mobile CPU. The i5 does have an advantage in single core performance. In the end it depends on what you actually want to do.
