FX 8120 encode video slow compared to 3770K?

I have 2 PC's one with an Intel i7-3770K and the other has an AMD FX-8120.

I used Adobe Premiere to encode a video and I noticed the AMD was so much slower compared to the Intel even at a higher clock speed.

This is my first time encoding on the FX-8120 cause I just finished building that and I've had the 3770K system for a while already.


I have the FX-8120 overclocked up to 4GHz while my 3770K is still at stock (although it does have 3.9 turbo boost).

When I tried encoding a 3 minute video on the FX-8120 it said it took like 30-40 mins, but when I encoded a 5 - 10min video on my 3770K it takes less than 20 mins like around 15 mins or so..


Does this just mean the AMD chip is that much weaker in encoding compared to the 3770K? Would a higher overclock help the AMD chip or not much?

Should I upgrade it to an FX-8350 if not then?

OR if not the FX-8350, then my last resort would be getting an i5-2500K or 3570K (I can't afford another 3770K) but only if these 2 are much better than the FX-8350 though.


Thanks for any answers and suggestions!
 
The FX8120 is worse than the 3770K in practically all applications. The FX8350 is neck-a-neck or superior than the 3770K in various tasks such as video encoding. The 3770K can also best the 8350, though not by much in not-well threaded applications. Piledriver had several performance upgrades over Bulldozer that you will appreciate for your tasks. They are not equal clock for clock, just in case you had that illusion.

So would you recommend the 8350 then for encoding? Will it be a huge improvement over the 8120 in encoding?

And also how does it compare to i5 3570K?

Yea sure :

Corsair 200R Obsidian
16GB Crucial Ballistix Sport
MSI GTX 660
Asrock 970 Extreme4 Am3+
120GB Samsung 840
500GB Western Digital Black
XFX Pro 550W PSU
 


It should work, just make sure your BIOS is at least P2.10. http://www.asrock.com/mb/download.asp?Model=970%20Extreme4&o=BIOS

You mean version 2.30 BIOS is that correct?

And I guess I will sell my 8120 back and try to get an 8350 then
 


Remember to check your BIOS version, P 2.10 is the first that can support the 8350, 2.30 optimizes it further, so remember to install P 2.30 before selling the 8120.

Alright thanks for all your help it looks like my BIOS was already updated when I bought it, I typed in msinfo32 and this is what it says

BIOS Version/Date : American Megatrends Inc. P2.30, 1/17/2013

Thanks for all your help!
 


He is upgrading to a 8350, which does not require OCing to get decent results. When he is running 2+ systems, don't give a "Intel system will save you power in the long run (10+ years lol)" excuse.

The BMs you show are at stock, put the 3770K to the same 4 GHz at the 8350 and watch the 3770K run away from, I have a few clients that work with video for a living and won't touch the 8350...also going from 4GHz on up the gap widens as Intel pulls further and further away....another plus for Intel is it handles much high freq DRAM and more of it - which comes in handy to the pros
 


He already has a 3770K. The FX@4.5 will also get quite impressive results. This is not an Intel vs AMD thread, and he already has both rigs, so there is no point in claiming Intel superiority. You do realize the 3770K Turbo Boosts to 3.9 when operating in these applications, right? They both have a max of 32GB of DDR3 RAM and if any of those processors benefits the most from higher RAM frequency, it is the FX 8350. It is not like the FX 8350 does not overclock too. The FX 8350 works wonders in properly threaded tasks and video encoding is usually one of them.

Not trying to make it so, somebody through up BMs at stock which isn't on an even keel, and saying the 8350 is better, which it simply is not, also commented that of my clients that do video work for a living - they won't touch the 8350, not even for home use
 

The thing is, the 3770K turbos to 3.9GHz, where it is quite close to the 8350's turbo. The 8350 is victim to AMD prejudice from poorly-threaded applications. Yes, a 4.5GHz OCd 3770K will decimate a 4GHz 8350 in encoding, but the 8350 can get close by OCing too .. then there is the price gap.. Anyways, he made a good choice upgrading to the 8350 from the 8120.

Actually, I just ran a quick test,

my brother has a 3570K at stock and so I tested encoding the same exact 1 minute video clip and on the 8120 it takes around 38 mins for the file and on the stock 3570K it takes around 7 minutes.

So I see even the i5 beats the 8120?


Should I go for 3570K instead because I actually found a good deal on the chip along with a motherboard. And I have a Noctua NH-D14 cooler so I can probably give it a decent overclock?

I maybe forgot to add in original post but I will casually be editing videos not all the time probably just once in a while, the PC is mainly for gaming, school work etc, so is the 3570K the better choice than 8350 since it is also less power consuming?
 


The 8350 is more suited against the 3770K for your tasks, considering the 3570K with a cheap, non-overclockable board is already in 4770K price range. Also, you already have a 3570K, it is called disabling Hyper Threading on the 3770K.

For power consumption, https://www.youtube.com/watch?feature=player_detailpage&v=4et7kDGSRfc#t=602s while I question the actual gaming benchmarks, this is the "STFU formula for Intel fanboys on power".

That was with the 3570K...think what it would be like with the 3770K and Hyper-Threading .......even faster...... ;)

Would you recommend me just get a 3570K over a 8350 then? Cause I can get it pretty cheap with a motherboard too, as where the 8350 i Have to pay full price.


And I also already have a 3770K system.

The 3770K is a 3570K with Hyper Threading enabled, if you want to simulate a 3570K, simply disable Hyper Threading. The 8350 is a nice rig to have an alternative once in a while and considering you will not use it that often, power should be irrelevant. What is the combo price for the motherboard and 3570K? I suspect it is a low-end non-OCable board. The 8350 is more of a "Jack of all trades" processor, not the best in single-threaded, certainly not the worst, but it does quite a good job in multithreaded tasks.

I actually will be using the PC alot because I am living somewhere else once school starts so that's the PC im Bringing with me. I know the i5 is much more efficient heat and seeing the performance it has it seems like a good deal. Could I go wrong with either one?
 


You can't really go wrong with either, I prefer the 8350, he prefers the 3570K, if the 3570K+Motherboard is cheaper, I would say go for it. If the 8350 (And you plan to keep the 970 motherboard) is cheaper, I would go for that. Heat should not be an issue, if anything, that D14 should either make run quite cool.

Alright thanks again for helping me to both, I just feel the 3570K is a better choice because most sites I check, people say the 8350 will increase the power bill and I am not paying for the bills so I don't want that to increase if it does. And It's more of a gaming first PC rather than video editing first so I think I should be fine thanks again
