Die shots of as many CPUs and other interesting chips as possible

Which one of the CPUs do you think looks the cleanest, aesthetically? The first Alpha looks rather chaotic, while the Samsung Alpha looks very uniform. That TI PA-7000 FPC looks like chaos. I think the two PowerPCs look the best, which is what I'd expect too. Well, actually I'd expect some of the other RISC to look simpler too...
