Hey I,m gona be building a new pc mostly for streaming and i cant chose between Amd ryzen 5 2600x with x470 Aorus ultra gaming and oc it to 4.2 or i5 8600k with z370 mbo. The other parts of the pc are 8gb 2400mhz Rx580 8gb...
 
Solution
The 2600X will stream better than the 8600k, but the 8600k will produce better frame rates when not streaming. You are going to have to make the final decision which is more important.


If you're already getting an 8th Gen Z370 motherboard, I'd recommend getting the i7 8700k for gaming/streaming because it has 6 more threads (good for multiple processes) and better clock speeds. It's considered the best processor in price to performance for gaming right now, and has room for extraneous processes like you'd need for streaming.

Removing the i5 8600k and just comparing the i7 8700k and the Ryzen 5 2600x, the Intel is maybe ~$150 more expensive (including motherboard) but many would say it's worth it for the increased performance you'll get.
Only comparing the i5 8600k and the Ryzen 2600x, it's pretty similar and ultimately it "depends". Still, I'd definitely go with the i7 8700k over either and there's a solid chunk of evidence to support this, but it's a little more expensive, like I said.

Prices are MSRP but here's the "average user" benchmarks for the 8700k vs the Rzyen 5 2600x (looks like some overclocking is factored in, too):

I wouldn't build a streaming system around anything less than an R7 or i7, and I would sooner use a 2600X than the 8700k if streaming. Intel's version of SMT is far less efficient than AMD's so only the first 6 threads are able to handily beat AMD's in IPC, whereas AMD's 6 higher performance threads being provided by SMT allow it not only to catch up but beat the 8700k when streaming in many cases.

At stock, once you start streaming a 2700X usually beats an 8700k, in some cases by a handy margin. The 2700X costs less, and the platform can cost less as well.

The 8700k turns in a fairly easy win when you're not streaming, and otherwise not stressing it's full thread count. It mostly wins due to higher clocks and slightly higher IPC. So when not streaming you will see higher frame rates on your 8700k

If you plan to use any kind of hardware streaming, such as Shadowplay or Relive, or even an external capture device, you can get away with even lower end CPUs.

Don't just take my word for it:

In reference to what bigpinkdragon286 said, it actually all depends on the games you plan on playing, and looking at the benchmark results (like he graciously supplied) and similar benchmarks is a good way to gauge what you need to spend and what you'd like to get. Note that the graphics card you get does have a result on the pairing performance with the CPU. If the benchmarks include about the one you'll be getting, then it's even more accurate.

The Ryzen 7 2700x is actually a little more expensive than the i7 8700k on Amazon right now, so you don't get much of a price gap when considering just the processor.

The R7 2700x could end up being a little better for streaming than the i7 8700k depending on what games you play and how they're optimized, but I'd go for the i7 8700k over the R5 2600x specifically, unless you want to spend less for only some difference in performance. (Since I one-upped the Intel I should have also one-upped the AMD CPU when making the comparison, my fault.)
 
Definitely shop around for pricing. Amazon's 2700X pricing is wonky.

Definitely look at the specific software you're planning to stream. As mentioned, every game has it's own particular performance.

Definitely take into account the amount of time you plan to be streaming vs gaming when not streaming. This can heavily weight your decision toward Intel, as the non streaming performance is usually higher.

Definitely take into account that you probably aren't going to need to be streaming over 200 FPS, and likely won't need that for non-streaming either.

And remember, no matter what CPU you go with, bad software streaming settings can bring any of them to their knees.
 
Best price to performance for gaming? We must be talking about a different processor here. The 8700k DEFINITELY is a strong CPU, but the 8600k/8400 demolishes it when it comes to performance/$.

One thing to note is that the price difference between the 8700k and the regular 2600 is quite more significant. I'd advise going for the regular 2600 along with a B450 board. The 8700k is around $250 more expensive when you factor in a decent CPU cooler (which the Ryzen chip comes with). Even if you went with the 2600X and a b450 board, you'd still be saving around $200. I'd recommend using that money to invest in some more RAM, as 8GB is cutting it really close, especially if you want to stream. Here's what I'd recommend getting:

Another thing to note is that if you're not using a panel that's over 60Hz, then the difference won't be realized at all. The 2600 is inarguably the best overall CPU for the money, at least when it comes to the current gen stuff. In most cases, it's kind of pointless to OC the Ryzen chip, as they already bring really good performance for the money.
 
The non-X Ryzen+ CPUs and their lower maximum boost clocks are pretty clear in the benchmarks, needing overclocking to reach something resembling parity in performance. The boost mechanism in the Ryzen+ X CPUs works well enough that overclocking them doesn't show significant gains.

I agree with your premise concerning a 60 Hz display. The OP should decide just how much performance he needs.
 

I just want you guys to tell me which is the better one for streaming, and i havnt got this mbo and i have a budget of 450/480 bugs and im not gona spend them on i7 8700k cuz it will cost me
350 bugs and the mbo is goin to be sh*t so i decide you to said me which is better between these 2 cpus amd ryzen 2600x or i5 8600k thanks.
 
The 2600X will not be bad at all. It is a VERY capable processor. I'd pick it hands down over the 8600k any day; it practically SLAUGHTERS the 8600k when it comes to streaming. https://youtu.be/GDggr3kt96Q?t=5m13s The 8600k's frame rate won't matter if you're running a 60hz panel, and even then, the difference won't be extreme. The 8600k will get better STREAMER-side FPS (meaning you'll get higher FPS on your side of the stream) but crumbles when it comes to the viewer experience.
 
Thanks, all of you for this stuff, so im havin 120hz monitor and i think it'll b good to get 2600x with b450 and one stick of 8gb 2400mhz ram. Like this is that what i learned from your support will be the best solution for now. And the games im gona be streamin are CS:GO, LoL, Fortnite, PUBG and Fifa, so if you have something to said about which cpu is getin better on this games while streamin i'll appreciate it a lot.
 
2 x 4 GB is better than 1 x 8 GB for the RAM. You want to run the RAM in dual-channel, and to do that, you need to buy the RAM in a proper kit, as a pair. You don't buy a module now and a module later, and expect it to work correctly, unless you want to take the risk of incompatibility from mixing RAM, and having to replace it all later. Unless the modules come in a kit, it's considered mixing.

Also, with Ryzen, higher speed memory makes a big difference. I would shoot for DDR4 3000, 3200, or higher if you can budget it, and definitely check the QVL list for your chosen motherboard to find RAM that should work out of the box with Ryzen, unless you like tweaking memory settings to make it stable.
