Ten - From the Anandtech Athlon 750 review: Thus, by looking at AMD's roadmap and the analysis we published right after Comdex, the introduction of the Athlon 750 is actually the introduction of the new K75 core that we talked about in that article. The K75 itself isn't much different from the K7 core; physically, it is a smaller die (102 mm^2 K75 core vs. 184 mm^2 K7 core) as a result of the 0.18-micron fabrication process but other than that the performance and features are identical. Maybe this will put to rest wild speculation about huge jumps in Athlon MHz performance by going to .18. Die size is what I expected. PB

Tenchusatsu, <The bad news: The L2 cache on the 750 is now on a 1-to-2.5 multiplier, instead of a 1-to-2. This affects the performance scalability of some benchmarks in Anand's suite of tests.> FWIW, in my book this is not bad news at all. IMHO, the decision to put the cache outside was smart. They would be shipping far fewer Athlons had they put the cache on die. And, they were smart enough to go to multipliers like 2.5 to ensure a smooth progression. Of course, once Fab30 comes online, the capacity issues will be mitigated and built-in cache becomes a lot more practical. Chuck
