Mac vs PC

Recommended Posts

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?

The scores are compatible between PC and Mac. The Mac does score better in other areas than the PC, except for the CPU. The reason is the i7 in the PC has effectively 8 cores, while the i5 has 4. The i7 can do almost double the work simultaneously, although the score per core is much lower since it is an older CPU.

Hope that helps clear it up

The .nbr files can't be loaded between OSes right now
