Ok, so other than the cost effectiveness of it, why are most custom gaming builds using the core i5 instead of i7? I've always thought the core i3 was a glorified celery processor (celeron) core i5 was a reboot of the core 2duo and core i7 was the way to go. But you see these recommended gaming builds on tomshardware and other sites, even the "building the ultimate gaming pc" and the budget is like 2k they still grab a core i5. Why is that?

As I've been told, by several gamers. For strictly a gaming build i5 is more than sufficent. i7 has hyperthreading which games don't make use of. But from a game performance level the cost for an i7 does not give you sufficient return on investment.

I don't game but thats the recurring reason I've been told.

Ok,but I also do CAD and blender and rip DVDs and I bought a core i7 laptop, so like, idk if I would notice a real performance hit if I had gotten a core i5 because I've never used a core i5

They all have hyperthreading. Even the Core i3 in my laptop (which is slower than most Core 2 Duo CPUs) has it.

The desktop line of i3 and i5 do not have hyperthreading since the 1st generation of the i series.

An i7 would help if you also did those task as it relies on the processor to complete the task and the time of completion would be dependent on the processing power of the processor.

Hi

 

i3 is basically dual core with hyper threading enabled and i5 is quad core with turbo boost function (HT not available). i7 do have both HT and turbo boost and is suited for high CPU hungry tasks. Most games works fine on a basic quad core CPU like i5 with stock clock speed. i7 is fine for gaming but choosing that won't give any major performance improvement in FPS as modern games are GPU hungry than CPU hungry.

 

Intel dual core = Basic two core CPU (HT and Turbo boost disabled) 

 

Intel i3              = Two core CPU with HT enabled (Hyper Threading)

 

Intel i5              = Quad core ( and some dual core models) CPU with Turbo boost enabled (HT disabled)

                               

Intel i7              = Quad core (and hexa core) with HT and Turbo boost (all goodies available)
