I'm working on an iMovie project and started wondering which computer I should use for the final render. It's going to be a few hours of HD video so I figure picking the right computer could save me literally MINUTES of time.
27" iMac, mid-2010. i7-870 with 4GB of RAM
"Mac", i5-2500K with 8GB of RAM
Both have 1TB SATA hard drives. Both are running 10.8.4. The i5 may seem like the obvious winner due to its newer architecture and higher clock speed, but the i7 has more L3 cache and (the potential for?) hyperthreading. CPU-World benchmarks
go either way depending on the test.
So which would render the video faster?
