Difference between 4th generation core i5 and i7

suvro · Oct 27, 2013

Dear experts ,

I am looking for your expert advice . Whats the major difference between Core i5-4570 & core i7-4770 . Desktop will be used for gaming & esxi/kvm labs so vt-x/vt-d required .

Regards

Mostly hyper-threading technology.

There are two differences beween the high-end i5s and i7s.

1. i7s have Hyperthreading enabled. This provides a serious boost to some highly concurrent workloads, or about 15% across the board when all types of applications are considered.

2. i7s have more L3 cache, typically 8MiB rather than 6MiB

There are some low-end i5s which have two cores present and Hyperthreading enabled. These are mostly used for tablets and ultrabooks.

All models support VT-x but only the non-k models support VT-d (Sandybridge-E, Ivybridge-E, and most likely Haswell-E excepted). Have you considered using VMWare Workstation for your labs? It provides shared VMs now, so the only real difference between Workstation and vSphere on a single machine is that VMWare Workstation cannot directly attach hardware to a VM as it does not use VT-d.

I will install esxi/kvm on base machine into a separate HDD . I will purchase 2 machine with same config thats why looking for your advice it will be worth for i7-4770 . In my country i7 cost 120usd more then i5-4570

For machines that are being used for virtualization I almost always recommend i7s. Hyperthreading is very useful

Thanks for your recommendation . I will consider asus maximus vi hero & 16gb ram . Is liquid cooler required for i7-4770 ?

A liquid cooler is not at all required for any of Intel's microprocessors.
You could get away with using the included reference cooler if you wish.

Liquid coolers are recommended for Intel's LGA2011 platform as those microprocessors are quite beefy.
