I can't imagine why anyone in his right mind would want to do such comparisons? For god's sake, what productivity is he talking about? The differences were less than a second!!! doh.gif doh.gif doh.gif doh.gif doh.gif

For argument sake, look at the benckmarks. He included launch app, find/replace, open, paste, arrange, format, fill bla bla bla..... Most of the functions were completed in less than 2 seconds. How much more productive do you want it to be???? To complete a function in 0.01 seconds??!!??!!

BTW, I guess the new mac is so productive that it does everything <0.1s? Which does nothing to the normal user as our reaction time is not that great either!!!

Furthermore, the tests were performed on only one single app opened! Try adding a firewall, a RTS anti-virus, anti-spyware, Bittorrent and folding. rclxub.gif rclxub.gif rclxub.gif

I mean, just to compare these basic functions is pointless. Why are we even discussing this???? rclxub.gif rclxub.gif rclxub.gif

I dont think the original author is trying to say that an 86 mac plus is better than a x2 4800+. Thats just stupid. What I do believe he'z trying to say is that the simple functions(eg. in word processing) that people use are still the same but due to the extra code added in the OS and programs etc, take longer now with newer comps. I noticed this myself while switching from a x2 3800+ 2GB system to a P3 500Mhz with 64MB ram. Sure the P3 had to be run with win98 and it could hardly run more than 2 programs at once but for simple tasks(like the ones mentioned here), I had about the same responsiveness from the P3 system as I had from my dual core rig. Just my 2 cents about this topic.

That's definitely true. Software nowadays comes with so many functions and has to load so many codes e.g. APIs that they are slightly slower.

However, this does not mean that productivity is reduced!!!

If the author really want a comparison, somebody could just write a simple software for dual-core that does all the function that he compared. Probably just need a few lines of codes anyway...... Then, we can assess whether it is slower. Anyway, what's the point, the differences is too insignificant!

Which I believe is the point of the article anyway. Programmers should go back to the basics and produce more efficient and simple code rather than make it more complicated. Any expert in this field please correct me if I'm wrong as I'm not really into this field but thats the conclusion I can come to with my (near zero) knowledge anyway.

That would be ideal but not in this day and age.

Software companies are producing apps that caters for everybody. They can't be making softwares that only cater for a certain segment of the market.

Take Microsoft word for instance. Frankly speaking, I only use it for typing notes, spelling check, thesaurus, some tables and pictures. That's all. However, there are other functions that I don't use but is used by other people like simple drawing, formulas, review, web page design, etc. And sometimes, there are those rare functions that I need that is available in Word.

Take the generic Paint program in windows as another example. It is so simple and easy to use, I usually use it to edit simple pictures to paste in this forum. However, when I want to do something more advance, the program doesn't have that function. So I have to resort to big-bulky full-of-functions/code apps like photoshop to edit the pictures.

Then there are people who start complaining that a certain app is not good as it does not have this function or that function. Imaging if microsoft word does not have the automatic spell-checker....... cry.gif

Of course, these days it is impossible to write programs with only assembly or C language. So the optimization won't be as good as oldern days (like the Mac PLUS). Heck, even C programming is a lot slower than ASM programming! (from my observation from internal test suites).

Yup. I still remember the days when people talk about code optimization. Assembly (ASM) language was the best!! However, it was also a pain in the neck to programme and virtually impossible to write for programs these days as there are million and million lines of codes......

It is in the software with millions of lines of code (such as an OS) that you typically see a lot of hand tuned ASM code. You don't have to do it all in ASM from scratch, you can compile it and then hand optimize the ASM code for certain critical stuff.  Obviously it makes sense to do for a function you call a billion times, or for an important inner loop.

LoL, my mistake. What was I thinking just now laugh.gif
Well said, the algorithm is very important. C / C++ compiler should not have too much problem as Intel is actually providing them to customers, but I dunno how efficient other high level language will be. From my experience in test coding, the most important part will be the algorithm within a FOR loop. If 1 loop is a bit slower, the end result will b farking slow considering there are million of loops (streaming for eg). Actually, some critical functions which access hardware directly (usually APIs) will be written in ASM or C programming.

Wow! That's deep but informative. Not for average users like me! sweat.gif

Thx for the info! thumbup.gif

Just curious, do average programmers do ASM these days?
