How much faster?

[TurboJobo]

I have an old 2013 late model, with only 4 gb of ram 🙁
im tempted to buy an a new macbook air would they be the same speed or air would be faster? because of not having retina less pixels would make it smoother no?

Computing is a bit more complex than "faster and slower" – It is actually very task dependant. Different things require different things from the system. What will you mostly be doing? – And are you running out of RAM (Check Activity Monitor). If you are, anything with more RAM will boost your system's performance with what you do. Almost regardless of other specs. Once you run out of memory, the performance drop off is steep.
Only thing the fewer amount of pixels will impact (almost anyway), is GPU performance. Not CPU or anything else. Well, again, for the most part.

From the little information you provided about your current Mac, and what tasks you perform with it, it's unclear whether it would be faster or slower.

Not worth it for a 4th gen 1.8ghz Broadwell chip. The "new" Air is essentially running 3 year old hardware. 8th gen Intel chips are launching in December. You also get the same trash 900P display that they have had since launch. Save up and get the new Pro. It's actually 3.02 pounds, which makes it just as light as the 2.9 pound "Air."

Well, you have to admit that there is a proper price difference though...

The upgrade to 8GB of ram would probably make it faster but the CPU/GPU jump from 3th gen to 5th gen is rather small. I'm quite happy with my 2015, but now that we are in mid 2017 I'd suggest considering a nTB MBP instead.
