Apple The "Macs are too expensive" argument is one of the most tiresome and long-lived flamewars in internet history. Obviously, Apple makes a premium product and charges premium prices, and you can always find a computer from another vendor that seems to match or exceed specs that costs less. But if you look at Apple's Mac Pro line, and compare it not so much to other vendors, but to the past lineup of Mac Pros, you discover some very unpleasant truths that help explain why Apple is enjoying record earnings for their Mac line, but doing so to the detriment of some its most loyal and valuable customers.

Sorry, computing will be CPU-bound for the next decade.


I must disagree. Computing is not really CPU-bound; rather it is main-memory (MM) speed bound. Nearly every other technology used in computers has increased in speed over the last 10-20 years by at least an order of magnitude more than MM.

The "hack" that has been used to ameliorate this problem is to increase the amount of cache available, as well as the number of cache levels. Managing this cache efficiently and correctly is one of the biggest problems faced in CPU/system design today, and it still wreaks havoc with the performance of certain types of software (since the cache hit ratio can dramatically affect performance).

If/when there is a commercially available breakthrough in MM speed (MRAM, memristor-based RAM, etc.), low-level computer architecture will change dramatically, as will programming techniques.
