So let's assume that the average person wanting to play SimCity is running a Core2Duo (released 7 years ago). It's hard to find benchmarks directly comparing a Core2 E6600 to something like an Ivy Bridge Xeon that you'd expect to find in a modern dual-socket 1U server, but even looking at a TomsHardware chart of x86 core performance can tell you that an i7-2600k is only about twice as powerful as a Pentium 4 HT660 (core-for-core) http://www.tomshardware.com/charts/x86-core-performance-comp...

Bottom line, the total cost of ownership doesn't at all make business sense to do right now. In 10 years, it very well might.

Main memory reference 100 ns 20x L2 cache, 200x L1 cache vs Send packet CA->Netherlands->CA 150,000,000 ns 150 ms

It's a little closer to 3x as fast

The core-for-core thing makes a huge difference in the real world that doesn't show up on single-core benchmarks. The HT660 was a good chip in its day, but it's at a four-to-one disadvantage for code that's multithreaded and/or running on a busy PC.

I think Sandy Bridge is my favorite CPU of all time. It does a truly massive amount of work without consuming significantly more power than the part it replaced.
