Hello,

I am on the verge of buying/building a new system for gaming/3ds max (Vray high end rendering) /Photoshop.

I am wondering as there is quite a price difference between the 4670k and 4770k is it worth me getting the 4770k and spending the extra? I mean will there be much difference when it comes to rendering times etc?

Thoughts appreciated.
 
Every heard of benchmarks? They're pretty useful for comparing processors.

The i7 is between 7.5% and 39% faster in the rendering tests. 7.5% was the speed up in the only "real" test (Blender, the others are Cinebench and POV-ray benchmarks) so I'd expect this to be more realistic than 39%.

As the only difference is the hyperthreading, you'll probably get a smaller speedup the better your IO system is. Running off a SSD/ram disk would probably make the difference shrink. Just intuition.
 
I just moved from an i5 2500K @4.5GHz to an i7 4770K @4.4GHz and the difference in render times is very noticeable. I don't see why the Blender test should be any more "real" than Cinebench, which uses the Cinema 4D render engine or POV-Ray, which is another well used render engine.
 
I bought a 4670k for gaming along side my two 780Ti's and i didnt like the performance, im pretty sure there was a bottle neck. I changed to a 4770k and thought i noticed a massive improvement. However this could all have been in my mind, all i know is im much happier with having a 4770k on the go.
I should imagine if i had been using something like Photoshop the gains i noticed would have been even bigger.

Go for the 4770k.

I suppose I'm saying that Cinebench return a score in "CBMarks", which could be scaled or weighted in some way, and not be as easily related to the real world as the "time in seconds" coming out of blender. That said, POV-Ray returns PPS which I didn't realise stood for pixels/second, which also makes sense.
 
I've actually found Cinebench to give fairly accurate results compared to real world experience. So the difference for video rendering will be near to the 39% than the 7%.

Maybe.

The best hard numbers seem to be comparing the 2600K to the 2500K. There's about the same % clock speed increase as between 4670K and 4770K, and exactly the same difference in cache (8M to 6M) so I think this is a good comparison.

In the 3DS Max tests the i7 2600K is 24%, 7%, 15%, 21%, 15%, and 11% faster than the i5 2500K in the order they appear in the link above.

I.e. 7%-24% faster, or 15% on average. There's a 44% price increase to get the 4770K over the 4670K, so it probably doesn't represent good value for 3DS rendering. Especially as if you have fast IO and memory I bet the difference decreases.

Although if time=money then every little helps.
