Ik kwam via JC bij dit anti-Mac artikeltje dat op zich wel grappig is. Je zult wel helemaal naar beneden moeten scrollen voor de up-to-date anti-Mac argumenten (het begint namelijk met niet-multitaskende Macs e.d. - dat kunnen ze inmiddels wel):
"The new PowerPC G4, architected by Apple, Motorola and IBM, is the first microprocessor that can deliver a sustained performance of over one gigaflop. In fact, it has a theoretical peak performance of four gigaflops."That's nonsense. The very nature of the Intel and AMD instruction sets allows them to easily exceed 1 GFLOP in most floating point code. In truth the theoretical maximum of 2GFLOPs for a 500mhz P-!!! or K6-2 or Athlon is very easy to comve very close to on real world code. Its part of what is leading to continually higher and higher frame rates of games like Quake. (I wonder if Apple is at all interested in running timedemos head to head with comparable PCs.)
"Velocity Engine"'s ability to hit 4 GFLOPs requires that back to back MACs are peformed on every clock (counting a MAC as two operations). No other combination of "Velocity Engine" code will deliver that level performance.
"The Power Mac G4 comes with an ATI RAGE 128 graphics accelerator."
Well good for you. As of 08/31/99, the ATI Rage 128 was two generations behind the state of the art. nVidia announced the availability of the G-Force 256 graphics accelerator which adds 50 GFLOPs of performance to an x86 enabled PC, in addition to an unparalleled level of graphics performance. This obsoletes the nVidia TNT2-Ultra which in turn obsoleted the ATI Rage 128. In Job's otherwise well calculated drive to subsume existing PC technologies, he failed to realize the incredible volatility of the graphics industry and has ended up with a lemon. [break] JC heeft zelf ook wat info over de G4: [/break] You know, I wish I could find a middle ground. We're in the midst of all this hype right now on the G4 -- it's a well performing part, in my opinion, and I do think AltiVec has much more promise than 3DNow! or ISSE, but it certainly isn't "nearly three times as fast" as a Pentium III. Like Athlon, it does appear to have some advantage over the PIII, but the advantages of the G4 are so far shrouded in mystery. Even with its spec scores, since the reported spec95 test system had twice as much L2 cache and faster memory (CAS2 vs. CAS3 has been reported) than the actual G4 systems Apple is selling, performance of the production part is uncertain and probably will be until Motorola publishes their scores at spec.org. I'm waiting diligently. [break] En om te voorkomen dat ik nu de hele Apple nieuwsgroep over me heen krijg, er is ook positief nieuws: [/break] Tired Of Hacks, U.S. Army Switches To Macs
After a series of hack attacks, the U.S. Army has switched from Windows NT to Mac OS-based servers running WEBSTAR Web server software for the Army home Page, according to the U.S. Army Public Affairs department. A report in ArmyLINK News says the Macintosh does not offer remote logins and is considered more secure.
. Denk maar eens aan de kunst van het weglaten (zie ook Pentium Pro) Minder instruction sets dus.
