G5 APPLE SERVER CODE
In fact, gcc 3.3 is unable to generate AltiVec code ANYWHERE, except on x86 where they added a special SSE mode because x87 floating point is so miserable. In this test, the G5 really shows superiority compared to the Opteron and especially the Xeons" From the numbers, it seems like gcc was only capable of using Altivec in one test, the third one.
With vectorizing, we mean generating SIMD (SSE, Altivec) code. First of all, the gcc compiler isn't very good in vectorizing. Why are they using an old version of GCC (3.3.x has no autovectorization, much worse performance on non-x86 platforms), then a brand spanking new version of mySQL (see above)? The floating point benchmark was particularly absurd: The article also goes out of its way to get bad results for PPC. this could be solved without switching CPUs. No real arguments that Power Macs are somewhat behind the times on memory latency, but that's because they're still using PC3200 DDR1 memory from 2003. OS X server includes a version of MySQL that doesn't have this issue.
MySQL has a disgusting tendency to fork() at random moments, which is bad for performance essentially everywhere but Linux. Okay, stop, I have to make an argument about why this article fails, before I explode. Also, the "Big Mac" cluster in VA tech speaks otherwise to raw performance as OS X was the OS of choice.
G5 APPLE SERVER 64 BIT
The 64 bit Apple Machines were running OS X Server 10.3 (Panther) and OS X Server 10.4.1 (Tiger), while our x86 machines were also running a 64 bit server version of a popular Open Source Operating Unix system: SUSE Linux SLES 9 (kernel 2.6.5). So, we focus on workstation and server applications, especially the open source ones ( MySQL, Apache) as Apple is touting heavily on how important their move to an “open source foundation” is. Thirdly, hardcore gamers are not the ones buying Apples, but rather, creative professionals. Secondly, there are fewer games available on this platform than on the x86 PC. Firstly, you have to pay a big premium to get a fast video card – as a standard, you get the ATI Radeon 9650 - even on the high-end PowerMacs. In this article, you will find a pedal to the metal comparison of the latest Xeon DP 3.6 GHz (Irwindale), Opteron 250, Dual G5 2.5 GHz and Dual G5 2.7 GHz.Īpple’s PowerMac is an alternative to the x86 PC, but we didn’t bother testing it as a gaming machine. If you like a less performance-obsessed article about Apple, OS X and the G5, you should definitely give Anand’s articles in the Mac section on AnandTech a read. But we think that you should have a decent insight to where the G5/Mac OS X combination positions itself when compared to the Intel & AMD world at the end of this article. This article cares about speed, performance, and nothing else! No comments on how well designed the internals are, no elaborate discussions about user friendliness, out-of-the-box experience and other subjective subjects. It is definitely the worst buyer’s guide that you can imagine. So, be warned this is not an all-round review.
G5 APPLE SERVER MAC OS X
This article is written solely from the frustration that I could not get a clear picture on what the G5 and Mac OS X are capable of.
G5 APPLE SERVER PC
Yes, you could find a benchmark here and there, with one benchmark showing that the PowerMac is just a mediocre PC while another shows it off as a supercomputer, the unchallenged king of the personal computer world. You guessed it - I am parroting Apple’s marketing.įor some reason, the performance of Apple’s gorgeous machines has been wrapped in a shroud of mystery. It is about the ultimate user friendliness. It is a professional 64 bit Dream machine with supersonic speed! It is beautiful.
