I'm not sure what you're talking about, because even for single-threaded applications, my current computer is a couple orders of magnitude faster than the computer I had 5 years ago.
- Steko 15y agoHe's talking simply about clock speed which used to make regular gains with Moore's law but ran up against the heat limits of silicon awhile back. The original article that this follows on gives additional background: http://www.gotw.ca/publications/concurrency-ddj.htm http://www.gotw.ca/publications/concurrency-ddj.htm
- abecedarius 15y ago100 times faster? (That's what I understand a couple orders of magnitude to mean. It's closer to 10 years of the old Moore's-law rate of improvement.)
- fjarlq 15y agoSo your computer today is 100 times faster than the computer you had 5 years ago? That seems like a stretch. What two CPUs are you talking about exactly? Hmm, I guess if you had an Intel Pentium III Mobile 750MHz (circa June 2000) five years ago: http://www.cpubenchmark.net/cpu.php?cpu=Intel+Pentium+III+Mobile+750MHz http://www.cpubenchmark.net/cpu.php?cpu=Intel+Pentium+III+Mo... Then if you got an Intel Core i7-2600K @ 3.40GHz that would score 100 times higher on the PassMark CPU Mark. But there's a 10 year gap between the release of those CPUs. Also, the Core i7-2600K has 4 cores and 8 threads, while that Pentium III had only one core and one thread.
- jquery 15y agoOrder of magnitude does always mean base 10. I was using "orders of magnitude" in base 2, the same base as Moore's law.
- sgt101 15y agoMy computer is many times faster than the one I had 5 years ago (or 3 years ago); my processor/cpu is somewhat faster. Faster memory, faster GPU - these make a big difference for me at least.
- jessriedel 15y agoOrder of magnitude always means base 10 unless explicitly stated otherwise.
- mappu 15y agoFurthermore, base 10 always means base 10 unless explicitly stated otherwise... wait, what?

- jerf 15y agoNo, it's not. Not in the same price range it's not. Not on the same tasks it's not. 100 times faster? You need to sell that beast for some real cash because you've got something nobody else does. The only way that can be true is if you didn't realize your 2007 computer was continuously in swap. Edit: Oh, sorry, read further down the thread, wherein your secret definition of "orders of magnitude" is revealed. Even then it's not true; the only place you're getting 4x speed improvements in single threading for the same price is either the very bottom of the market (maybe) or in certain benchmarks that carefully test only certain aspects of the single thread performance. It's certainly not across the board.
- jquery 15y agoYou made the claim that computers had stopped getting faster. Do you stand by that statement? Please define what you mean by speed.
