How much improvement can I expect with this new CPU?

[Perene]

First of all, this is what I am using today:

Q9450
DG41TY Intel MB (onboard video)

Corsair DDR2 PC2-6400 2 GB 400 MHz
Corsair CM2X1024-6400C4 1 GB

Samsung 753LJ (2 HDDs)
CaseMall 500W Total Power Plus - ALL-500TTP Power Supply

Windows 7-32

***********
The new PC may be this one:

**********************************

Windows 7 or 8 - 64

Core i5 4460
ASUS LGA 1150 Z97M-PLUS (MB)
Kingston HyperX 8GB 1600MHz DDR3 CL10 DIMM HyperX FURY Black Series HX316C10FB/8

SSD Samsung 840 EVO 120 GB (used for the OS and a few things)
Samsung 753LJ (2 HDDs - used for the rest)

Seasonic ATX 520W S12II-520 Bronze Power Supply

Perhaps the GTX 650 will be used, but right now no video card. So consider this new config without the GTX.

I have a difficult question (if it's an easy one I have not found a precise answer yet), how much improvement can be expected in this new setup?

For example, consider the CPU alone. If using Sony Vegas PRO 11.0 and the Q9450 it takes 20 hours to render a 2h45m video recorded in the best quality from a camcorder with few additions, how much time will that same task require in the i5 4460?

I need to know the percentage. Noticed most of the comparisons are only from Core i3, i5 or i7.

I can also choose the Core i7 4770, and perhaps I will, it seems the difference is about 20-30% in this case.

I saw the benchmarks.

What I never saw was a comparison between the Q9450 which I currently have and the i5 4460 or i7.

I used Tomshardware's comparison chart with your cpu and a Haswell i5 and i7 cpu:

Either Haswell is a huge increase from what you have but the i7 is definitely the way to go for heavy rendering.

Get a Xeon E3-1231 V3. It's an i7 on the cheap.
If you're not overclocking (and you wouldn't be with a non-K processor) you don't need the Z97 mobo.

Also, you want DDR3-1600.

Because the Xeon has no integrated graphics, a cheap video card (e.g. GeForce 210) will be required.

Well yeah, but you'd want that with Vegas Pro anyway. Just not a 210.
I'm not sure if 11 was ever updated to use newer cards, so you might want to be on the lookout for a 400 or 500 series card.

I agree with others, you'll need hyperthreaded CPU to get most of performance for the money for your use case. Jump to i7 isn't that expensive when you factor in how many yrs you'll be using it. Your Q9450 came out in 2008.

The Xeon is your best bet. With it you're looking at around 2-3 hrs for same render..

No, Haswell is only a little over twice as fast, not 10 times faster.

Say what you want, I know Sony Movie Studio Pro & Sony DVD Architect Pro. I render Blu-rays regularly. With the LGA 775 Xeon quad it would take up to 14 hrs for a 20Gb image. Switched to LGA 1366 rig with Xeon 5570 quad with hyper thread and that dropped my render time to 3 hrs. Changed out the cpu for a X5650 Hex and heavily overclcoked have gotten that render time down to 1 hr & 10-20 mins..

He is going from LGA 775 quad to Haswell Xeon w/HT and you think it's only twice as fast? Wrong..
