Spectre 13" base cpu is :
Intel® Core™ i5-6200U (2.3GHz, up to 2.8 GHz, 3 MB cache, 2 cores) + Intel® HD Graphics 520 (with 8G memory)

The 2015 macbook air is an i5 at 1.6ghz (apple never really say which but I am guessing a gen behind the spectre.

The spectre is a decent machine and shouldnt be slower than the apple when both running windows
Mines actually the i5 4200U, so 1.6GHz up to 2.3GHz in 'turbo' mode (there's been a few different versions of the Spectre 13 over the last few years)

Sat here on Chrome with nothing else open its using 10% CPU and 36% memory, this jumps to around 20% & 42% respectively when my beefy spreadsheet is number crunching.

My Excel is 2013 32bit, if the fact its 32 & not 64 makes a big difference?

Really 64bit excel is only going to be a advantage with really large spreadsheets

Your cpu is probably similar in power to the mac one then if its 1.6ghz, but I'm not sure of the thermal envelope of either which can be more important now as once it gets up to its TDP (say 15w) it gets throttled.

32 bit Excel will only address 2Gb of available memory, so the fact that the laptop has 8Gb is irrelevant when running the program. https://support.microsoft.com/en-gb/kb/3066990

from your usage percentages it doesn't sound as though memory or CPU is an issue.

Do you have add-ins loaded in the PC version of Excel that are doing something in the background?

It's curious that CPU% goes up by 10% constantly when Excel is loaded - you'd only expect to see CPU impact when the sheet is calculating.

What are the figures for the Mac?
