Memory performance (continued)
Not only are our 3D graphs indulgent, but they're useful, too. I've arranged them manually in rough order from worst to best, for what it's worth. I've also colored the data series according to how they correspond to different parts of the memory subsystem. Yellow is L1 cache, light orange is L2 cache, and orange is main memory. The red series on the Extreme Edition graph represents L3 cache. Of course, caches sometimes overlap, so the colors are just an interesting visual guide.

The A64 3400+ produces some very impressive latency numbers across the board. Let's see how those translate into real-world performance.
