Benchmark numbers in Geekbench

[weaztek]

I've been going off Geekbench benchmark numbers when I'm shopping for new Apple gear. I know that the benchmark numbers don't exactly translate to real-world usage but I've found it's a fairly good metric.

My philosophy has been upgrading a computer once the Geekbench numbers at least double from my existing machine.

Here's my question... Does doubling the benchmark number (e.g. single-core: 1000 to single-core: 2000) mean roughly twice the performance for apps that support the speed boost?

You sorta answered your question. If the app supports the speed boost then that implies that it was cpu bound and it works in a way that can utilize the increased speed.

In the real world it may or may not make a difference. There can be bottlenecks elsewhere, such as device I/O.
