- inactive, on 10/12/2007, -0/+10so, because the brand new Core 2 Duo 2.0ghz is faster than a 2 year old dual 2.0 G5, that means the G5 was always garbage? Because to me, it just shows that Intel has made more progress in the past few years while the PPC has stagnated, which was one of the reasons for thw switch to Intel in the first place...
NEWSFLASH: New computer faster than old computers... Film at 11... - LaughingMan11, on 10/12/2007, -0/+5First of all, the batteries in the MacBook and the MacBook Pro are very much different from the Lithium Ion batteries in the Powerbooks and iBooks that they replaced.
The MacBook line uses lithium-ion polymer batteries. This allows the batteries to be thinner, but also less flammable, because it does not use an organic solvent.

As for 2nd button pointing devices, the new MacBooks arleady have effectively a second button capability built right into the trackpad. If you use two finger scrolling, tap with two fingers can be used as a right-click. I use it all the time. It works great, assuming you are the type to use tap-to-click on the trackpad. - Vandel405, on 10/12/2007, -2/+7It's also slower because pointers take up twice the size. Object happy applications have lots of pointers.
Intel has some performance wins for 64bit (more registers). On PPC, basically the only thing that changes is that your pointers take up twice as much memory. - LaughingMan11, on 10/12/2007, -0/+5This is not too surprising. The Mac Pro and the iMac are also getting the benefit of going from 8 GPRs to 16 GPRs as the ISA has changed from x86 to x86-64...while on the PowerPC side, regardless of bitness, you've got 32 GPRs.
Also, I think the compiler may have a lot to do with this as well. Perhaps GCC building for x86-64 is more mature than GCC building for PPC-64. - inactive, on 10/12/2007, -0/+4A single core chip is faster than a slower single core chip?
No ***** eh?
dumbass. - inactive, on 10/12/2007, -1/+5not to mention a Mac Pro vs a PowerMac
faster architecture, faster bus speeds, faster memroy
state the obvious and get on the front page of digg.
no wonder the US is behind the academic power curve. - inactive, on 10/12/2007, -0/+4I meant to say dual core chip faster than a single core chip
/self pwnt - abdulla, on 10/12/2007, -0/+3So you can't get this card in an ExpressCard format? Isn't express card linked directly to PCIe?
- neko, on 10/12/2007, -1/+364-bit is about increased bragging factor and lack of a flash player =) and I wouldn't go back.
- Thinine, on 10/12/2007, -1/+3Anyone surprised by these results is an idiot. After some proper optimization I'm pretty sure the PPC version would see a speed up, if only a slight one. Merely turning on the 64-bit compile option is a ridiculous way to test.

If your Laptop is not set up for it, where will you put the Aircard's antenna? My ThinkPad has a Sierra Wireless card but it has the antenna for it, so that is what makes it work. - Hayl, on 10/12/2007, -2/+464-bit is about more RAM not about performance.
- JimXugle, on 10/12/2007, -1/+3@fjc8,
I'm looking for a Unix-Based Notebook with manufacturer support of Said Unix OS and a metallic exterior. Know of a non-Mac brand that offers such a notebook?
@LaughingMan11
Thanks for the info - dwtd, on 10/12/2007, -1/+2I can't look at benchmarks without pretty bar graphs. It's like a book with no pictures... :P
- Chealion, on 10/12/2007, -0/+1@jfpoole - Well... damn. I was wrong. Sorry Internet.
- Philodox, on 10/12/2007, -2/+3"Geekbench runs faster in 64-bit mode on Intel-based Macs, but slower on PowerPC-based Macs. I find this incredibly surprising."
Does anybody else find this very poorly worded? It sounds like the author is comparing 64 bit mode between Intel and PPC and is shocked when one is faster. - JimXugle, on 10/12/2007, -0/+1@abdulla
Excellent point. This is what originally gave me the idea, but I would prefer not to have an easily-removable card that I could possibly loose. - streak, on 10/12/2007, -0/+1This is not news to me. The picture for G5 is actually much worse than geekpatrol paints, as far as the penalty for running in 64-bit mode. Compilers can have a lot to do with the relative results and IBM has a compiler for Mac OS X that optimizes well but can ONLY produce 32-bit code. IBM never updated their compiler to produce 64-bit code for the Mac... and probably never will, since Apple switched to X86 and X86_64.
The other advantage to X86_64, which has been noted by others, is the availability of twice as many general purpose registers in 64-bit mode, relative to 32-bit X86 code. The G5 doesn't gain this architectural advantage when moving to 64-bits, but it does get penalized just the same as X86_64 for the increased memory required by 64-bit pointers.
The Mac Pro doesn't improve as much as the iMac when moving to 64-bits because the Mac Pro uses higher latency (slower) FB-DIMMs. - tumult, on 10/12/2007, -2/+3geekbench isn't so hot, though :( remember, just because you hear numbers doesn't mean they're true.
- pgiessel, on 10/12/2007, -2/+2The processors aren't truely 32 or 64 bit, especially when you conisder things like AltiVec, which is essentially 128bit.
- jfpoole, on 10/12/2007, -1/+1@Chealion,
Geekbench does use Altivec (and SSE, too); Geekbench has a number of SIMD tests (like the dot product test). - Chealion, on 10/12/2007, -2/+2pglessel - Geekbench doesn't use AltiVec.
- jfpoole, on 10/12/2007, -3/+1No, the same chip is faster in 32-bit mode than 64-bit mode (or vice-versa, depending on the architecture). The article is comparing the same chip in different modes, not different chips in the same mode.
- JimXugle, on 10/12/2007, -9/+4Great!
Still waiting for non thermite-ion Batteries, Core 2 Duo (64 bit, as opposed to the 32 bit Core Duo), a 1.3+ Megapixel integrated iSight, and a 2nd Mini-PCI Express slot before I get a MacBook Pro Though.
Whats the 2nd PCI Express slot for you ask?

Something else I'd like in a MacBook would be a 2-buttoned pointing device. But I know that isn't going to happen.
Did I come off as sounding like a troll? - EmmEff, on 10/12/2007, -9/+3These sorts of benchmarks make me laugh... it just shows how much of a POS the PPC chip is/was, despite Apple's "supercomputer" label. I was never a believer in the PPC chip (despite the fact that I own one).
- fjc8, on 10/12/2007, -8/+0I'm glad my PC notebook has Core 2 Duo and a second PCI Express Mini Card slot along with a two-buttoned pointing device (that works as the middle button if you click both at the same time)
No camera, but it's a business notebook, so it's more durable than a Mac.
