The 3770k and FX-8350 are essentially tied in x264 performance.
Yes, the FX-8350 is a significantly better value for an encoding box.

tied in performance? $120 difference not worth it?

lets do the math:

20 min video ~26400 frames

i7@74.16fps first pass 356 seconds or ~6 minutes
8350@62.07fps first pass 823 seconds or ~13.75 minutes

i7@14.55fps seoncd pass ~30.25 minutes
8350@15.16 second pass ~29 minutes

so a 20 minute video will take the 8350 42 minutes and 45 seconds whereas the i7 36 minutes and 45 seconds. you will have the first pass of another 20 minutes video FINISHED with the i7 the same time 8350 will finish the second pass on the first video. if you need to encore 10 videos the i7 will be done an HOUR before the 8350.

to say that the ~$120 difference in price for the i7 isn't worth the ~14% increase in work production?

look above, you just got done an hour eariler every day ( out of an 8 hour work day ) when paying that much more. you just finished a two week project slightly over a day earier, can send out an invoice and can start the next project.

not worth it? not for sporadic youtube videos of gaming but in the professional environment, most definitely. and i can say that from personal experience.

edit: this little topic started with someone spewing some FUD that the 8350 beats an i7 encoding x264 video and i have shown in many ways that is simply not true. so with that i consider the topic closed, there is simply no sense to it and i have better things to do.

The only way for that to happen is if AMD magically had around twenty times its RD budget.

Intel's annual RD budget is more than AMD's entire company value. One does not simply compete with something like that.

How are comparisons between Ivy Bridge and Piledriver in CPU bound games relevant to Steamroller being on schedule? The topic has deluded to a nostalgia circle-jerk and a video game benchmark collection containing processors that are not Steamroller.

Also, stating that I never provide anything of value is your opinion, which again, is you asserting yourself self-importance. I could go out on a limb and say that your most used nouns are AMD and fanboy, which is hardly a legacy.

Please refer to my avatar and sig, have a wonderful day.

You can be a gamer and an enthusiast at the same time. OH, and fyi.. I have no brand preference I go for what is best at the time, or what I determine to be the best at the time. Also, he wasn't bullying you. Your posts did not contribute to this thread in any way whatsoever. The worst part of that is how low quality the posts were in this thread (not all of them but some of them) and yours were lower than even that bar.




BACK ON TOPIC.

I really hope steamroller gives AMD the IPC to compete with Intel haswell... Ivybridge is a year old and being competitive with Ivy will not be a win for AMD in my book. Piledriver was a step forward after the original FX was a pretty large step back. Competing would be winning in several benchmarks and not just a benchmark here or there. I look forward to seeing it. I had to switch to Intel about 18 months ago after being with AMD CPUs for 10 years.

I appreciate the honesty.

To clear some confusion, my signature doesn't say that you can't be an enthusiast and a gamer at the same time. What my signature expresses is that the vast majority claim to be enthusiasts when they are in fact just gamers with brand preferences.

To also clear some more confusion, if like you say, the majority of the posts in this thread are bad (I agree), then him singling me out and insulting me is indeed bullying.

To appease 2010rig, here is me contributing to the news of Steamrollers release being on schedule in the same fashion and relevancy as everyone else.


Come on guys, this attitude is asinine. Shake hands, relax, it's just a discussion not a life or death situation.

8350@62.07fps first pass 823 seconds or ~13.75 minutes

your calculation of 823 seconds is wrong i think

i7@14.55fps seoncd pass ~30.25 minutes
8350@15.16 second pass ~29 minutes

.......... (i am quoting only the above part of your post)

.

I have bolded and underlined the part where I think you have grossly miscalculated the 8350's numbers and in the process inadvertently showed it in a poorer light than it deserved

I believe you are wrong here .... the reason is 26400 frames encoded at 62.07fps will consume just 425 seconds (26400/62.04=425)
425 seconds ~ 7.05 minutes
You (probably) mistyped it as 823 seconds, which turned out to be nearly 14 minutes

So, doing the math right:
i7@74.16fps first pass 356 seconds or ~6 minutes
8350@62.07fps first pass 425 seconds or ~7.05 minutes

i7@14.55fps seoncd pass ~30.25 minutes
8350@15.16 second pass ~29 minutes

Total:
i7-3770k ~ 36.25 minutes
FX 8350 ~ 36.05 minutes

They are tied !

Of course, now I am not at all familiar with x264 encoding, so I am basing this corrective post based purely on my numerical knowledge.
So, counter-corrections welcome smile.gif

Intel to release an 8-core chip is all it takes to send AMD back to stone-age.

yeah there is a big boo boo on my part. i also didn't use the proper frame rate by using 22fps an old broadcast standard instead of 30 fps for flash, online publication or 27 fps for DVDs.

so since my math gets flonky, lets keep it simple.
first pass
i7@74.16fps / 8350@62.07fps = 1.1947800869985500241662638956017
second pass
8350@15.16fps / i7@14.55fps = 1.0419243986254295532646048109966

for the overall difference of 0.1528556883731204709016590846051 in favor of the i7. now when would that make a difference? not for encoding short gaming videos to upload to youtube. but as i said before; when working on a several days or weeks long project the i7 would be better.

btw, nice first post you get a rep for that.

now i am done.

Doesn't the second pass still take several times longer?

8350@15.16fps / i7@14.55fps = 1.0419243986254295532646048109966
the 8350 beats the i5 when using software based video encoding because it can handle more threads but not the i7 that can handle as many threads.

now will SR get more competitive? lets look at where that would matter most:
Quote:
AMD also advanced single-core execution by implementing 5%-10% more efficient scheduling,

that close to the 15% difference but not quite there.
