Intel's Penryn Core Part II First Performance Benchmarks, The Power of SSE4
(Author: MS, April 18, 2007)

Rendering and Encoding

Most Rendering benchmarks are primarily limited by the number of instructions per clock cycle and the CPU frequency, whereas cache size and bus interface don't weigh in much. Examples are Cinebench multithreaded benchmark that reflects the number of cores, execution units per core and the frequency of the processor itself.

Interestingly, a 14% increase in core frequency bumps up the results by 25%. Bear in mind though that the results are not scaling in a completely linear way, however, the Yorkfield (quad core) and Wolfdale (dual core) appear to handle the workload a bit more efficient than the Kentsfield.

The situation changes dramatically in DivX with VirtualDub 1.71, in which the Penryn core plays out the SSE4 instructions to literally blast the older Conroe core out of the waters.
