Recently purchased a second 7970 to run crossfire in my FX8350 rig.

Upon checking my performance results, it became clear that my rig wasn't keeping up with the masses which were Intel based..

I keep hearing that gaming at high-res is GPU dependant and CPU makes next to no difference blah blah blah....  but this is not the case as i have discovered the last few days.

I've been a loyal fan to AMD for around 10yrs now, vowing never to buy an Intel product since their unscrupulous business practices a while back..

Anyway, i decided to swallow my pride and make peace with Intel this week , and purchased a i7 4770k CPU with a Maximus VI Hero board..
All i can say is WOW !!!
This little gem destroys my FX8350 in everyway... unbelievable !!

My crossfire performance has shot up an average of 15-20% leaving everything at stock speeds...  cranking up my 7970's by 200Mhz results in performance that cannot not be matched by my 8350... 

Why did i do this ?   Because i wanted to squeeze as much performance as i possibly could out of my 7970's, and i knew that they were held back by my 8350. I also wanted the extra video encoding performance the 4770k offers.

I was going to purchase a FX9590 but the power consumption is way too high.

I have enjoyed my run with AMD, but they have fallen behind too far now and things are looking very bleak for them in the performance sector...  I hope they catch up some day..

That's cool and all.  It's great that with your upgrade you got a substantial increase in performance.  I have an 8350 in my system, and I'm still happy with it because it's kind of a bang-for-buck kind of thing ... when I bought it at Micro Center, it was on sale for under $200, so at the moment I feel no remorse.

I don't play any games where any one of my CPU cores are loaded to 100%, or any combination of cores coming close to 100%, so I know I'm not CPU bound. Once programmers start really using multiple cores (it's almost 2014 and that statement still holds true from back in 2005 when dual cores were the big thing, how pathetic), the difference should decrease, but I'm happy with my rig.

I'm going to wait a few years then bump this thread just so you have to re-read what you've said here and have an epic facepalm... or a least by then I hope it would cause a facepalm... otherwise that's even worse.

Oh yeah, I should probably include some general geekery about there probably being more multithreading in your system than you realize, and how not all tasks benefit from multithreading in the first place.

Anyway... I still have an AMD chip in Stockpile, my media server/HTPC.  The desktop has an i5 in it now since thats what I had on hand the last time something died.  Can't say I really noticed much of a difference, but I've never built a multi-GPU machine before.

Bang for buck AMD wins hands down..  no argument there.

But for high end multiGPU they just don't cut it at the moment.  I don't think they have the horse power to feed data quick enough to more than one card at a time...

 

Day to day stuff, no difference tho...

Except that the majority of games are not able to efficiently use multiple threads and cores, which is what this topic is about. I'm not talking about media encoders, operating systems, professional applications, and things of that nature, I'm talking games. It may change as programmers have to learn to leverage multiple slower Jaguar cores in the XBOX One and PS4, much like the programmers of server and HPC applications have known how to do for many years. But as it stands now, games still benefit from a higher per core IPC and overall clock speed vs core count.

The hard part of multithreading isn't so much in creating a thread and giving it a chunk of code to work on, but in making sure all your threads play nice together.  The spawning and creation of threads would be pretty similar in any kind of application within the same OS, but of course nobody knows that except those people who have actually done it. 

Not to mention that you can't really judge the effiency of threading very easily at all without access to the source code, let alone using things like Task manager which were never built for it in the first place.

I do think that the next generation consoles using standard AMD multi-core processors can only mean good things for the threading of future multiplatform games.

Quite beyond that, Mantle offers a lot of promise in eliminating a much API overhead.

It may be the case that high single core speed becomes quite irrelevant for gaming.  The implementation of Mantle in Battfield 4 shold provide a preview of how the theory meshes with reality, but overall I think it will be a solid year before we can know for sure how much PC gamers will benefit from the double-win by AMD in the console market.
