Retina iMac 64-bit Performance

64-bit Geekbench 3 results for the Retina iMacs have appeared on the Geekbench Browser. Let's take a quick look at how they perform compared to the non-Retina iMacs.

Single-Core Performance

Multi-Core Performance

The Core i5 Retina iMac is slightly faster than the other Core i5 iMacs, and is competitive with the Core i7 iMacs in single-core performance. However, the Core i7 iMacs are up to 20% faster in multi-core performance.

The Core i7 Retina iMac is significantly faster than all of the other iMacs (including the Core i5 Retina iMac), with at least 15% higher single-core performance and 10% higher multi-core performance.

These Geekbench results aren't surprising since all of the iMacs use Haswell processors; any performance increase is due to the increase in clock speed.

How does the Retina iMac perform compared to the Mac Pro?

Single-Core Performance

Multi-Core Performance

The Core i5 Retina iMac is faster at single-core tasks but slower at multi-core tasks. The Core i7 Retina iMac is also faster at single-core tasks (25% faster than the fastest Mac Pro) and is also faster than the 4-core Mac Pro at multi-core tasks.

If you're considering replacing your Mac Pro with a Retina iMac then these results show it's not a bad idea provided you don't regularly run heavily-threaded applications.
