Hi,
thinking of setting up a render machine for an upcoming project. Checking PassMark - CPU Mark I liked the Intel Core i7-3770K @ 3.50GHz because of its benchmark to price relation and I was wondering what else factors are important to find the right CPU.
For example some CPUs have more cores but less benchmark values ... how is this to be seen for the CPU decision ?
If you have tips & hints for building a great render machine pls share.

Regards,
Frank

Look also at www.maxwellrender.com/benchwell for Maxwell specific performance. That's really all that matters for Maxwells render performance.

ya, the list is cool, but can't figure if a cpu with more cores has more render power, or can work off rendering better, or if more cores in a cpu more likely help different tasks rather than one rendering task ...
Was thinking of a multiple cpu setup.

The more the better.... Cpus/Cores. . Whatever

Single cpu 3930k is a good choice still

Multi cpu (4 socket), the amd 6300 series looks like a good performance-price factor, at least for maxwell

Cores schmores, doesn't matter as long as you pick the CPU that is within your budget and has the highest BM score You can do multiple things on your CPU at the same time if it has 1 core or 50, mostly it depends if it all fits within your boards RAM.

The term "cores" in the benchwell list is a bit misleading, because the listed "cores" are actually threads, mixing up intels real and hyperthreaded (virtual) cores and AMDs "cores".
If you compare CPUs you can roughly say more cores with the same or higher speed = faster CPU, yes. But then you have to look at the architecture. So the slower systems with more cores are either older ones, slower clocked or AMD systems... (or all in one )

Current AMD cores cant be compared to Intel cores. AMD has bundled to cores in one module sharing the same cache. So two AMD cores are more like one Intel core + hyperthreading, so maybe 1,5 cores.

Just compare the listed CPUs and not the cores... but be careful, there are many faulty and incomplete entries (overclocked CPUs, wrong frequencies, etc.)



The problem of the most multi cpu systems is a lower single core performance compared to a single cpu system - or even better, an overclocked single cpu system...
