Excel and Hyper Threading. Would love your advice on getting the right specs for PC's

hi guys

We seem to have issues with our accountants and their Excel from time to time. They use a lot of macros/formulas and VLookups. The specs of most of their PC's are i5-7200 3Ghz, with 8GB RAM. Most of them do not have SSD's. They are using Microsoft Office 2013 64-bit editions. Their Operating Systems are Windows 7 Pro-64Bit.

I've been reading that apparently for Excel to function at its optimum and not 'hang/freeze', they need CPU's with Hyper-Threading?

Have we been buying the wrong PC's as they don't have Hyper-Threading?

Thanks for helping

Not sure about hyper-threading but have you made sure Excel is set to use all available processors?

You can do that in the Formulas section when you goto Options>Advanced.

It might also be worth looking at the formulas they are using.

PS Are you sure the PCs don't have hyper-threading? See here to check.

Do we know whether Excel with large formulas needs a lot more RAM and more robust processor? I've literally asked a colleague at one of the investment banks who works with hardcore Excel content and he has 32GB ram along with an i7-6700 CPU.

Thanks for helping.
NorieAnalyst Assistant Commented:

I'm sure the more memory you have and the higher spec the processor won't do any harm but it really might be worth looking at the formulas being used - are the using a lot of full column/row references in formulas, do the use array formulas a lot etc.

There's also other things to take into consideration , excessive formatting, use of charts, etc.

PS What sort 'hardcore' content' is your colleague working with?
YashyAuthor Commented:
Thanks Norie for responding back. My friend works with risk and quantitative methods, theirs is heavy on array formulas, complex statistical data that has to be compiled.

I don't know enough about the actual depths of what my colleagues here are doing as I'm not an Excel wizard like they are. I will have to look at whether they do use references and array formulas.
