Apple Hardware VP Defends Benchmarks 1081
He said Veritest used gcc for both platforms, instead of Intel's compiler, simply because the benchmarks measure two things at the same time: compiler, and hardware. To test the hardware alone, you must normalize the compiler out of the equation -- using the same version and similar settings -- and, if anything, Joswiak said, gcc has been available on the Intel platform for a lot longer and is more optimized for Intel than for PowerPC.
He conceded readily that the Dell numbers would be higher with the Intel compiler, but that the Apple numbers could be higher with a different compiler too.
Joswiak added that in the Intel modifications for the tests, they chose the option that provided higher scores for the Intel machine, not lower. The scores were higher under Linux than under Windows, and in the rate test, the scores were higher with hyperthreading disabled than enabled. He also said they would be happy to do the tests on Windows and with hyperthreading enabled, if people wanted it, as it would only make the G5 look better.
In the G5 modifications, they were made because shipping systems will have those options available. For example, memory read bypass was turned on, for even though it is not on by default in the tested prototypes, it will be on by default for the shipping systems. Software-based prefetching was turned off and a high-performance malloc was used because those options will be available on the shipping systems (Joswiak did not know whether this malloc, which is faster but less memory efficient, will be the default in the shipping systems).
As to not using SSE2, Joswiak said they enabled the correct flags for it, as documented on the gcc web site, so that SSE2 was enabled (the Veritest report lists the options used for each test, which appears to include the appropriate flags).

If I recall my history timeline correctly, after CodeWarrior came
- the Apple MPW "MrC" compiler (better code than CodeWarrior 1.0, but with a wacky command-line "IDE"), then
- gcc for PowerPC (cruddy code back then), then
- the Motorola PowerPC compiler (better code than Apple's compiler, with NO IDE - it plugged into the CodeWarrior or MPW IDE).
- Then Motorola inexplicably stopped selling their compiler.
- Later Motorola bought Metrowerks.
- Somewhere along the line, gcc learned to generate better PowerPC code.
- Eventually, Apple pretty much shelved their "MrC" compiler, and settled on using gcc for Mac OS X
- Monday, Apple released their "Xcode" environment -- still using gcc, I believe.
Apple's MPW tools are still available (free) here [apple.com] for Mac OS 7/8/9.

The gcc "Haifa" scheduler was donated by IBM Haifa, by the way, so I think it's not surprising that gcc produces good code on powerpc.
On Intel it's quite the same, except that gcc does not vectorize code. From what I have seen, however, icc's vectorizer is not very useful either. I recently tested ogg-vorbis (which is a plain C floating point intensive benchmark) with icc 7 and gcc 3.3 and the gcc version was actually faster than the icc version (on my Athlon XP, target CPU pentium3) despite icc having vectorized several loops.
So all this "vendor-optimized C compiler" stuff is really besides the point. No C compiler will ever be able to match the quality of hand optimized assembler code, and the most important code (ffmpeg MPEG-2 decoder and MPEG-4 codec) has already been hand-optimized. You might be able to squeeze anoter 5 percent out of your code by using a vendor C compiler with insane optimizer settings, but what good is that if the end user is only going to use gcc anyway. I know I am, so I find the numbers for gcc actually more useful for comparison purposes than some vendor C compiler comparison.
Also, we don't want to encourage vendors to produce super vendor optimizing compilers, we want them to optimize gcc (so that everyone benefits, not just their users). So the more benchmarks are done using gcc, the better!

First most research on compilers are being done at big corprorations. IBM being the single largest as I understood it.

Second if you were to put a good optimization in GCC it wouldn't take long before all other compilers had that optimization as well. GCC is OSS afterall.
We did comparisons between GCC and SunCC on UltraSPARC. SunCC minimal optimizations (O1) beat GCC with maximum optimizations (O4).
I'm just finished a course on vectorizing/parallelising compilers. There the situation is that even the best commercial compilers are pretty much equivalent to junk. Implementing the vector algorithms is a lot harder though. Even compared to complex SSA-form optimizations.

On our computation cluster we use specialised compilers. I care how it runs on all of it for real world use. But no hardware manufacturer does those extensive of a tests - they pick the best of the ones they can claim "fair" on usually.
And lastly, in the end, who cares? Unless you are regularly running 4 hour jobs from a console it is irrelevent. It is more important that you are productive with the interface and that is personal choice. Few consumer tasks (and even programming tasks) require that power - and the stuff that does is generally handled by specialised hardware. Then if they have the fastests today they won't tomorrow.
...but is gcc equal across architectures? (Score:5, Insightful)
In this case, performance will in part be a function of how mature and optimized the generation of code for the advantages of that particular chip is.
Because there is no guaruntee at all of fairness by using gcc for both processors, except of course if we had the expert opinion of someone intimately familiar with gcc's code generation for both processors, using gcc for both processors would seem to be little more than a marketing tactic to give the appearance of fairness and credibility.
It seems to me that a better test is to take the best compiler widely available for each chip, and then run your tests with the produced code. Now, this isn't necessarily real world application testing, but that isn't what we are necessarily looking for here.
How well the processor performs with code generated by the best generally available compiler, is, apart from extraordinary measures, the best prediction we have of how generally the processors will compare for any given well-written, production quality code.

Jeez - to hear people around here, you'd think that innovation, style, performance, and the courage to move forward agressively and definitively with new technologies doesn't come at a price.
What other comapny would develop all these technologies to hardware and software maturity as part of a new hardware platform, then bring it all to market with system software already written (by the same vendor, I might add) to take advantage of new hardware features?
Those things DO come at a price. The price begins at $1999.00 for the 1.6GHz G5, or $799.00 for an eMac.
As long as there are people who just want to get work done on their computers without hiring an IT department or worrying about who is responsible for which component of the system, Apple will still be around.
I bill around eight hours a day with my Macintosh - the $400.00 price premium over PC hardware at the time I bought my G4/800 simply isn't an issue - over the lifetime of the machine, I'll probably bill at least two hundred times that amount for work made possible by its existence.
That $400.00 up-front cost means that I don't have to spend my time - my extremely expensive and finite time - having to deal with at least two vendors just to get a system with competitive hardware, a competitive OS, and support for them both. If your time isn't valuable, by all means cheap out and build your oft-touted (and perfectly capable) PC from parts you buy at Frys. $400.00 means nothing to professionals - it's cheap support insurance.
I hope Apple sells a TON of these machines - because they're practically the only personal computer company willing to take the initiative and responsibility for supporting hardware and operating system on equal terms.

SPECint: As far as SPECint, the Power4 is not in the lead (1113 @ 1.7Ghz), but is still respectable when compared to Pentium4's (1200 @ 3.0Ghz).
The G5/970 should do similarly or better than the G5/970 (since the G5/970 is running at 2.0Ghz vs Power4+ 1.7Ghz). One caveat is that the G5/970 has a smaller on-chip second-level cache (512kB vs 1.5MB), which will hurt its performance on some codes.
Certainly Apple's test uses a drastically different compiler than the reported SPEC results. This results in absolute numbers that are lower, but Apple's relative comparison is still reasonable, IMHO.

Of course the G5 along with all the goodies they come with are incredibly great, but this isn't apple's mainstay... it's simply another selling point.
If they become entrapped in having to proove themselves through benchmarking every new release, it won't be long before their entire image would have to live up to being ahead at all costs.... and guess what... they ARE going to fall behind again.... and then they'll leap ahead again.... and then they'll fall behind... etc....

You just know if it was to Apples advantage they'd have compiled with their best compiler and dont teh comparrison with those numbers vs Intel's so this situation has been contrived to an extent.
With Intel charging what they do for their compiler developers can be reluctant to pay extra for it, I expect almost everyone (on Windows) would use it if it were free. I know I would, but I can get by without it. I don't really have much sympathy for Intel here, they make billions of chipe, make significant performance claims based on their own compiler, yet charge for it to the point where many developers simply stick with Microsoft's compiler that they've already spend a fair bit on. Now Intel is upset that Apple used gcc, well more people might use Intel's compiler if it were easier to aquire, and clearly it would benefit Intel. If they want to run there business where everything is a profit center and they don't have to be smart enough to evaluate obvious but intangible benefits that's their business, but this is part of the price you pay for charging an arm and a leg for your compiler when you should be in the hardware business and giving your compiler away to help your customer gain the benefit of faster code from the applications they purchase.

* I suggested that Apple's OS release schedule was unparalled based on the number of features being introduced. This isn't an achievement driven entirely by the programmars in Cupertino. With the Mach / BSD underpinnings, open source software can be easily ported over to the new machine (see: fink, apt-get, etc.). In many cases (e.g. Safari, ProjectBuilder, etc.), Apple is applying a flashly UI on top of standard source. The result is a relatively small number of programmers producing a large number of features. Compare this to Microsoft which uses entirely custom code and where you need a large number of programmers to get a small number of features. Compare this to the Linux model where you need a large number of programmers (as most are part-time), to get a moderate number of features. Solaris and other commercial Unixes also have this advantage, but neither has been quite as driven; I don't understand why this is so.
If this analysis is correct, OS X should have an impressive feature and Microsoft will need to change their OS development model. Linux / BSD, if they can avoid fragmentation, will continue to provide much of the R&D that the other OSes rely on.
