The best CPU?

I'm doing okay with my little old system from a few years back, but on this board I see that many are using pretty exotic hardware.

I came across this article and was curious if anyone has done something similar.

The guy's conclusion was that it made more sense to spend the money on a fire-breathing GPU card. But that was for Premiere; maybe for Vegas the results would be different.

what is you current spec?

I do agree that, if compare the 5820K or 5930K with the 5960X, I also would not go for the very high priced 5960X and rather spent the money on a R9 390 Fury X. I do however prefer the 5930K with its 40 lanes over the 5820 with only 28 lanes.

On the other hand, don't skimp on your processor! The fastest GPU in the world won't give much benefit to a weak processor.

This benchmark chart is extremely helpful to me. I edit AVCHD with a processor that rates 6000 -- but you could go as high as 10,000 rating before the prices start getting astronomical.

@Steve

Interesting chart but doesn't help much with Vegas. The highest CPU on it wouldn't do any better then a 5960X overclocked. For Vegas, clock speed wins over cores any time. However, two cpu's running at the same clock, cores may win up to the amount of cores Vegas actually utilizes, I believe that is 16, physical or hyper threaded.

Like oldsmoke says, that is a good chart for obtaining a high Passmark score.

Vegas performance is a combo of CPU MFLOP performance, and CPU core count. This is due to the way codec decoding, and timeline playback are multithreaded. In addition, the GPU is paired with the OpenCL compute units on CPU for floating point performance boost. Optimizing your CPU MFLOPS and combinng that with the highest GFLOP performing GPU you can afford would be your best combo.

RAM speed and quantity should not be forgotten in order to keep both the CPU and GPU fed. To little memory, and its like supplying a lawn mower worth of gas to an 8 cylinder engine. The engine may kick over, but not fire on all cylinders optimally.

These are great points, guys!

I forgot to mention. Do not forget that Codec optimization can help improve playback and rendering.

Try converting all source footage to Intra frame codecs:
* Cineform.avi
* HDCAM-SR and SR-lite.MXF
* XAVC-I for 4K, better off with the above for HD.

XDCAM-EX and 422 is also highly optimized in Vegas and will perform better than .h.264.mp4, .MOV, .MTS, or GoPro native format.

My experience has been that both CPU and GPU help performance as a powerfull GPU doesn't cover every sin. I went from an i7 2.5 GHz CPU to an i7 4770k 3.5 GHz that changed SVP12 into a non crashing NLE. But when I took other's advice to get an R9-390, Vegas really started to sing. Full res playback as well as decent 4K footage playback. And finally - GREAT render speeds.
