How much difference does a Core i7 make compared to a Core-i3?

Hi Guys,



I would like to setup a new computer for Power Director. Will choosing a higher processor model make a big difference in terms of making the video? Some friends were suggesting that I just invest in a graphics card. I find some cheaper laptops now with Core-i3 processors but with good NVIDIA graphics cards and memory... Will it make a big difference if I get an Core-i7 with the same NVIDIA graphics card, or will the difference be negligible? The price of the laptops are quite significant (the Core-i7 ones are almost double the cost of the Core-i3). Thank you.

welcome back.

you need to read some past forum posts -> New PC for video editing; advice sought.

Is it worth buying a new GPU to reduce render times in PowerDirector? and PD14 seems out of working power?

get the fastest CPU that you can afford without breaking the bank and live in an unheated/no ac garage for a while...

so watch out for the shrewd sellers -> Lagging computer while editing

and Hardware advice ;sample Intel Xeon E5-2660 v1 with GeForce GTX 1050Ti .

most of the workstation & high end pcs suck up a lot of electricity. pcs that i recommend doesn't. it's around 95w to 125w max. same with GPUs, too... because when it comes to editing, i am the bottleneck so i have to watch my wallet(sounds like a broken record).

make sure to go to the https://www.cpubenchmark.net and put some i3, i5 & i7s and gpus, too. higher the CPU & GPU number less pain and higher the wattage means a hole in your wallet. you will feel it especially if you're running under w10... ^^

if you can't digest, then let me put it in an easier terms. i3- three lane hwy, i5- five lane hwy and i7- seven lane hwy with the median. which one do you think, move two way traffic faster during the rush hour?

Hi Pepisman,

I read through these posts. Yes, faster will always be better, but I was hoping for something of a more "practical" answer. For instance, if I make a 10 minute video at high resultion, and it takes 30 mins to render on an i3, will the same video take only 5 mins on an i7 or will it take 25 mins to render? Both 5 mins and 25 mins rendering time is an improvement from the 30mins rendering time in my example, but both improvements are vastly different. I suppose that if the rendering time were to improve from 30 mins to 25 mins, I would prefer the i3 considering the cost difference in equipment. However, if the difference is like the 30 mins for i3 and 5 mins for the i7, I would seriously consider the i7. From what I read, the video cards don't make much of a difference in rendering speed, the CPU makes most of the difference. I hope that the info is correct. Your 3 lane highway vs 7 lane highway analogy sounds nice. Thank you very much, but I do hope that there was a way to make this difference in speed show up in more practical terms. I mean, when I watch videos comparing the rendering speed of PD vs Vegas and Premiere on YouTube, they show how many mins it takes to render the same video on different software. I was hoping that we can compare the rendering time of the same video on different computers with the same software. This will essentially help us decide if the extra money spent for the upgrade is worth it.

Unless I have missed it somewhere, you don't say what the resolution of the material you work with is. What I can say is that if you want at any time to work with 4K (oh yes you will) then an i7 or better is almost essential. Those files are so big an i3 just could not cope. An i3 was designed primarily for stuff like Word and spreadsheets.
If you have access to 10 minutes of 4K material, have a look at ynotfish's chart at the penultimate post on PDnews sticky on the PD16 forum. I am certain that ynotfish has an up market processor so just compare his times with yours. I am willing to bet that even if you try it with 1920x1080 instead of 4K. The times in the chart will beat yours using an i3.
I hope you can prove me wrong
Conclusion: if you want to continue using one of the best user-interfaced NLEs on the market that also is one of the fastest. Get yourself an i7 at least.

Thank you Robert,

Actually I haven't really worked in much material yet. My 2nd gen i3 is very slow even for smaller videos. So I am looking for my most cost-effective upgrade solution.

I intentionally didn't put the video resolution. It's hard enough to get the type of answer I would ideally like (like a head-to-head time comparison) because I presume very few people would work on both an i3 and an i7 on the same project. I think if I were to specify a type of file or resolution, it will be next to impossible to get an answer.

So I am leaving the file type open so that anyone who has had experience working on these systems may contribute irregardless of the type of file. I mean, I've watched videos comparing rendering time and video quality of PD vs Vegas vs Premier on YouTube for instance, and I just accept whatever resolution or type of material the author use, I can't impose it on the authors. What is important for me in terms of comparison is that the file types will be comparable (not necessarily the same), just to give me an idea of how much faster one will be over the other.

An estimated answer will also just be fine. Thanks so much. All replies are greatly appreciated.

here's a poops and giggles, us, forum members did with PD14 and GTX 960. GTX960 Performance Comparisons after reading that click on this PC Perf Stats
mine is last of the bunch in H.265 and mediocre in H.264 rendering.

Hey Pepsiman,

Your PC Perf Stats file was really helpful! I need some help interpreting it though. Which among the lines describes the rendering time? I can't help to notice that there are 1st Gen Core it's being compared to a 5th gen in the chart. That is so cool!

I think it depends on your budget. If you have a limited budget, I think the i3 core with high vga card specification is a good choice. Customize also with the desired software needs. run 3 unblocked

pc perf stats is when the PD & HA works together... if you look at the Duration (mm:ss) that is the total rendering time. if you look at mine then you can see that just changing the GPU in a same system made a lot of difference in rendering HEVC H.265.
HEVC H.265 column, GTX 960 rendered in 03:12 whereas GTX 750Ti did it at 17:01. look right of mine and you can see Julien had same GPU as me but with faster CPU, his rendered at 12:29.
AVC H.264 column, GTX 960 03:15 & GTX 750Ti 03:19 and Julien's faster AMD CPU at 01:42.
another difference is when the GPU supports the H.265, rendering H.265 and H.264 is similar but GTX 750Ti doesn't support HEVC H.265 so rendering time is longer due to CPU only... today's cpu that supports encode and decode HEVC H.265, will have shorter time, too...
i've experienced about 10% reduction in rendering time when i used SSD drive.
everyone had 12GB to 32GB memory but PD14 used max 8GB... so when your system has total 8GB then you'll feel the pain...

Based on your findings, the video card does make a big difference if I use H.265. This sort of runs contrary to the stuff I read that the video card only helps in rendering effects and has little to do with rendering time. I suppose those things I read are only true if the video card isn't supported or optimized.

I plan to make a YouTube channel. Should I use H.265?

YouTube accepts HEVC H.265. i've been uploading AVC H.264 at 105 Mb/sec and YT downscales to 22 Mb/sec and still look good. also read CL EULA and do the right thing...
