Primate Labs has just published and compared the new Retina iMac 64-bit performance benchmarks with non-Retina iMacs. According to a 64-bit Geekbench 3 result for the Core i5 Retina iMac, it seems a bit faster than the other Core i5 iMacs, and competitive with the Core i7 iMacs in single-core performance. However, the Core i7 iMacs are up to 20% faster in multi-core performance.
These Geekbench results aren’t surprising since all of the iMacs use Haswell processors, so any performance increase is due to the increase in clock speed. If you’re wondering how does the Retina iMac perform compared to the Mac Pro, the following results should give you the answer.
As you can see, the Core i5 Retina iMac is faster at single-core tasks but slower at multi-core tasks. It is likely that the Core i7 Retina iMac will be faster at multi-core tasks than the 4-core Mac Pro, but still slower than the 6-core Mac Pro.
Do you plan on buying a Retina iMac any time soon?
