The larger the cache, the better. Especially for rendering. A larger
cache means more rendering binary code can live closer to the CPU along
with more data. Since rendering is such a repetitive process, cache is
very important. It keeps one from taking too many memory access
performance hits.
I have seen nothing but stunning benchmark results for AMD Dual Core chips.
As far as motherboards go, when it comes to AMD opteron dual proc
systems, there are two main types:
1) The type in which a single memory controller is shared between the
CPUs (in which case one CPU has slower memory access due to using a
hypertransport pipe to get access to main memory)
2) The type in which each CPU has its own dedicated memory controller.
This is faster.
The introduction of dual core opterons will make for a frightening
machine for certain, with four cores spread over two CPUs. Though, with
the uncertainty of mental ray licensing on dual cores... I don't know
how that works out with regards to $$. Anyone know if mental images
ever got around to telling us how licensing will be affected by dual
core chips?
