I'm hoping to use Novabench to help me rank computers that I look after. After trying a few, I actually came to one of the more powerful iMacs we have here, bought in 2014. It's a 3.2Ghz quad core i5, 27" iMac with Geforce GT 755M graphics. It's scores are as follows - Total - 887 RAM speed 9018MB/s, 8192MB System RAM RAM - 179 Floating Point Ops - 154765984 Integer Ops - 301771808 MD5 Hashes - 1285767 CPU - 508 3D FPS - 530 Graphics - 166 Prim Part 930GB Drive Write Speed - 112MB/s Hardware - 32 My desktop computer is a Windows 7, 2010 Dell i7 860 (2.8GhzQC) with a Geforce GT330 graphics card which scores as follows - 13/07/2016 10:44:06 AM Microsoft Windows 7 Professional Intel Core i7 860 2.80GHz @ 2794 MHz Graphics Card: NVIDIA GeForce GT 330 Total Score - 972 4087 MB System RAM (Score: 140) - RAM Speed: 9220 MB/s CPU Tests (Score: 668) - Floating Point Operations/Second: 206911944 - Integer Operations/Second: 727758736 - MD5 Hashes Generated/Second: 952824 Graphics Tests (Score: 137) - 3D Frames Per Second: 419 Hardware Tests (Score: 27) - Primary Partition Capacity: 465 GB - Drive Write Speed: 52 MB/s I would have expected the iMac to be of later generation processor, and overall score higher than my PC from 4 years before. Are the scores between OS'es supposed to be consistent with each other, and do these look right? Also, Mac .nbr files from all the macs I've saved them from appear "corrupt" when attempting to load into a Windows version of Novabench. Are they not cross compatible?
