i5 good to stream or better to get i7 ?

Recommended Posts

Posted · Original PosterOP

Is a i5 good to stream with ? I have been looking around and found a i7 4790 fro about $60 more and want to know if it will be worth spending the extra money to get it. If i did all it means is ill have to wait another week or two to get a water cooler for it

If you're streaming, the I7 will do A LOT more. On a 4690K you'll start to see some bottlenecks when you do that kind of heavy multitasking.

i5 will be fine if you use Quicksync as the encoder. That moves all the CPU intesive tasks to the iGPU of the i5, which means no burden is placed on your CPU.

i second this

My 4790Ks da bomb for streaming. I hate to be held down by multitasking.

My i5 streams 1080p 30fps fine in any game I've tried (60fps in game, but 30fps on stream), but when I try to bump the stream up to 60fps it really starts to shit the bed. If your internet is capable of 1080p 60fps then I'd say get the i7, but if it's only capable of 1080p 30fps/720p 60fps then speaking from experience; the i5 is pretty capable.

Depends. For mostly gaming and casual streaming (meaning you are doing it for fun, and not looking to start a career on twitch), i5 will work fine - many games are not that CPU intensive. For those times when there are issues - you can use QuickSync. Now, the problem with QuickSync - it has lesser quality-per-bitrate than x.264. And the lower the bitrate, the higher the difference. Below 5 mb/s - noticeable even without zooming in. Hence most "professional" streamers prefer software x.264

 

If you do want to stream seriously, then i7 is an obvious superior choice. i7-4790 is fully capable of running any AAA title and streaming that title at 1080p 60fps with x.264.

 

However - if you are not interested in overclocking - take a look at Xeon E3 1231 V3 - http://nz.pcpartpicker.com/part/intel-cpu-bx80646e31231v3- It is basically i7-4770 in terms of performance, it is cheaper by quite a bit. The difference is that Xeon is a server CPU, that has higher binning (rated for 24/7 lifetime operation, lower TDP, boost is more stable), some specific server/workstation features but also lacks HD 4600 integrated GPU - which you probably don't need, because I assume you have a proper GPU. It also lacks QuickSync, but again, you don't need it, because it can handle software x.264 without any issues.

I fourth this

I fifth this

 

However, just remember that GPU encoding requires a higher bitrate to look as good as CPU encoding, From my experimentations, its about 1.5x - 2x increase from CPU bitrate will give you the same quality in GPU encoding. So if 1500Kbps CPU encoding looks good to you streaming, then you're gonna need 2250Kbps - 3000 Kbps for the same level of quality. The point of no benefit is about prolly 20Mbps onwards.

Well i do like to not close crap so a I5 might slow down a bit

Quicksync i need to google this xD i have a adm cpu atm

I think we all hate that :D

I My internet can do 1080p 60fps but would only do 720p 60fps at the most :)

Oh i forgot i can get server cpu xD i might have a look around at the prices for some if not just get that one as i don't care for over clocking at all really, plus i dont have to turn my pc off really any more xD

 

Just use quicksync.

To google i go xD

I use my i5 with a Gtx 970, using OBS with quick sync and everything in game AND drivers set to quality vs performance. The stream looks good, all text is readable, though there is just a touch of blockiness. And everything is running 90+ fps for me (OBS limits stream to 30fps anyway, unless you tell it otherwise)

Using OBS really isn't that heavy on a system. I used to game AND stream on a A10-6800k APU just fine. Internet bandwidth I'd my biggest limiter for streaming, add I'm only at 4mbps upstream.

If you already have a GPU, consider the Xeon E3 1231V3.

 

It's essentially an i7-4770 without an integrated GPU for close to an i5-4690k's price.
