I mean, if I use the same RAM I have now, I won't get any speed improvements if I get a much faster CPU? I have i7 920 now.

Why not? Faster CPU is good for speed.

Ok so faster RAM just ensures that more cores will be used?

It doesn't ensure that, it just generally helps the CPU. If the CPU is not capable of utilizing the RAM at fast speed then no matter how fast the RAM is, the CPU will not work faster.

In other words, get a fast CPU with large cache and get a fast RAM. Together, they will ensure high speed of rendering. Look at the example above (i7 3930K 4 Ghz, DDR3-2133) for reference.

What I specifically wanted to know was if replacing my i7 920 with an i7 4770 which is benchmarked as being exactly twice as fast at the same ghz and cores will actually speed neatvideo up twice as fast, 50% faster or make it faster at all? If I'm using the same RAM I am now that is.

Your guess is as good as mine here because I don't have a machine with i7 4770 to run a direct test and moreover, I don't even know how your existing machine performs in the Optimize test.

I provided a log from Optimize from a system with i7 3930K 4 Ghz, DDR3-2133, so you could directly compare that with your machine now. If i7 4770 is faster than i7 3930K 4 Ghz then the results will be even better.

Your log doesnt mean anything to me because we dont have the same RAM. I have a DDR3 4GB 1333. We dont match at all.

If you need to see the log here it is
Frame: 1920x1080 progressive, Radius: 1 frame

CPU (8 cores) and GPU (GeForce 9500 GT): error

Best combination: CPU only (5 cores)

If the 2133 means 2133 mhz then thats pretty fast but I heard it eats up 100 watts so if thats what faster RAM is, more mhz then I probably wont get a replacement. Thats why I needed to know if I can expect a consistent increase in speed if I get only a faster CPU.

Also, if I can ask a off topic question: how come the memberlist feature is disabled now? I took great pride in my postcount before and knowing I had the highest. Now I wont know! Sad

1333 MHZ is not very fast. 1866 or 2133 MHz would be better.

Your current system reaches about 4 fps. Our 7 3930K 4 Ghz, DDR3-2133, reaches 10.2 fps, which is 2.55 times faster than 4 fps. It would probably be lower if the RAM was slower.

I don't know if replacing just the CPU will help you increase the speed by the factor of two with the same RAM. In any case, I recommend to upgrade the RAM to something faster along with the CPU.

Regarding the memberlist, it is disabled for a reason: to avoid abuse by spammers.

I dont mind if a new i7 wont be exactly twice as faster for neatvideo as it will for regular benchmarks, but what is a fair estimate to expect? 50% faster, just a little bit faster cuz my RAM sucks so much?

Do you know what the typical power consumption of 1866 MHZ RAM is?

My guess is about two times. It is a guess, remember.

I don't know how much 1866 MHz RAM consumers (check the specifications of the manufacturers) but I do know that it may need a passive heat sink.

Hmm wtf I search and see RAM typically takes 2-3 watts. I've been told it takes like 50. Oh well, good to know it doesnt.

For the record, your 3930 at 4ghz is vs my 920 at 2.8ghz. If we adjust for the difference in frequency, your machine is actually 1.82x faster than mine.

Thanks for the answers.
Do I still have highest post count since I cant access memberlist?

1920x800, not 1920x1080?

Sorry, wrong source files. Tomorrow or the day after, i will check the fps for 1080
