i3 6100 instead of i5 3470 - worth it?

[Arthm0st]

I have i5 3470, and I wanna take a new cpu's generation, cause 3rd a lttle bit slow today in my opinion. Is there any reason to change it on i3 6100? Thanks!

I say yes and here is why. it'll be easier to upgrade later.

In multi threaded applications the i5 would be quicker , but besides that the 6100 would be the right choice.

Going from an i5-3470 to an i3-6100 sounds like a downgrade to me: the IPC gains between Ivy Bridge and Skylake are quite small, you lose two physical cores and half the L3 cache.

I'm going to be keeping my i5-3470 for a few more years and by the time I actually need to upgrade, I will hopefully be able to get a 4C8T CPU with better IPC for under $200 thanks to AMD's Zen.

Okay, do you play any games on your pc? And what is your gpu?

Also I can exchange it to an i5 3570K just paying the $50 right now, one guy want to get my i5 3470 instead of his 3570K.

Here's Anandtech Bench comparison between the i5-3470 and a 35% overclocked i3-6100TE

Not many results for this combination but the i5 pulls ahead by a significant margin in most of them.

I use my PC mainly for work and don't do much gaming, still using an old HD5770. For driving a GTX1080, I'd still pick the i5-3470 over an i3-6100 though: the most GPU-intensive games tend to also favor CPUs with more than two cores.

If I were in your shoes, I'd either go with the i5-3470 or throw in another $60 or so extra on top of the i3 to go with the i5-6500/6600: I'd rather pay $200 up-front for an i5 than pay $140 for an i3 and then pay ~$200 to upgrade that to an i5 later. Going straight for the i5 ends up $140 cheaper. If I couldn't afford the i5-6500/6600 but already had the i5-3470, I'd go with that.
