Leopard will be 64 bit, judging by recent entries on the WebKit changelog (fixes for building with 64 bit AGL, etc...)
ehurtley said:NT had a 'Workstation' version that the Alpha was marketed toward. However, even when run on Alpha or MIPS 64-bit processors, NT was still only 32-bit. (There was even a PowerPC version of NT for a while.) Alpha had the longest life of any of these alternate platforms, lasting all the way through NT 4.0's run. (The MIPS and PowerPC versions were canned before NT 4.0 finished it's run; Alpha and x86 are the only two platforms that made it all the way to Service Pack 6a.)
DeadKenny said:and NT was not marketed as a desktop operating system. It was for the server room back in the day.
Sun has its new massively multithreaded Niagara chip on the market now, and it's kicking butt in some markets.wms121 said:..from the Register last year:

Has any of this changed?
Sun is waiting for a "software paradigm shift"..and is using AMD 64's in the
new "Web Servers" (or whatever those boxes are).
Because Intel is their competitor.Why don't they use the Intel Itaniums?
Because that would be retarded. Itanium chips cost as much as entire Macs do, or more.Why doesn't Apple use an "Itanium" (gee..Steve..where is my iToaster?)
Because it's relatively complex, and many people have no idea what they're talking about.Why does this site argue about whether or not something is "really 64 bit"?
Who is they? What is it that they supposedly want to tell us?Don't they want to tell us?

janstett said:Itanium is proving to be a dead end. Intel launched it years ago (IIRC around 98-2000) and it was so different from the existing architecture that you might as well treat it like an entirely different chip from X86 like a DEC Alpha, and as a result expensive, and nobody wants to adopt it.
slooksterPSV said:Not good enough for me. When performance is everything, Mac wins. A compressed version of RISC, or minor-risc of cisc isn't good enough for me. CISC is CISC even if its 99.999% RISC IMO, still, I wonder how much faster any of the computers would be if they had RISC instead of CISC w/RISC Chopped down Instructions. - -sorry can't think of a better way to phrase that.
ehurtley said:The cheapest of the new dual-core Itanium 2 9000-series chips is only $696 (even this 'cheap' model has 6 MB of cache,) compared to the Core-based Xeon 5100 series' cheapest $256, and Core 2 Duo's $183. (For comparison, the upcoming NetBurst-based Xeon 7100 series' cheapest is $856.) Compare the MOST expensive chips in each line: Itanium 2: $3692 (this one has a whopping 24MB of cache!) Core Xeon 5100 series: $851, Core 2 Extreme: $999, Netburst Xeon 7100 series: $3157 (With only 16 MB of cahce.)
So you can see that Itanium 2 is reasonably priced in comparison to Intel's own Xeon 7100 series. (Both are targeted at similar markets.) And you can even get an Itanium 2 cheaper than the highest end Xeon 5100 series, and noticeably cheaper than the Core 2 Extreme. (Which I find ironic, since Core 2 Extreme is SLOWER than the fastest Xeon 5100 series processor.)
JackSYi said:I think the Merom is Intel's first 64 bit mobile processor.
Catfish_Man said:Yeah, I exaggerated somewhat, but if you want even vaguely competitive integer performance you'll need the higher end ones. Core 2 is coming around 3k SPECint at the high end, and even the really expensive I2s only get just over 1600.
ehurtley said:Indeed it is. Although AMD has had 64-bit versions of their mobile chip for a year now. (And Sun for a while crammed their 64-bit chip into a notebook.)
maxvamp said:Lessee...
32X2=64..Twice as fast
With a Merom, I am waiting for....
- My games to run twice
- Oracle to run twice as fast
- Render / compile times to be twice as fast
- Safari to be twice as fast
- Rosetta to be twice as fast
- DVD burning to be twice as fast
- Productivity to be twice as fast
- Floppy / USB drives to be twice as fast
- love making to be ...no wait....![]()

poppe said:Excuse my ignorance, but I didn't think Bit Rate ( is that what its called) worked that way? Does it really make programs run Twice as fast?
Mac Rules said:So will Merom, Conroe and Woodcrest be 64-bit? Also will leopard support 64-bit processing like Windows XP 64 for example. I'm really looking fo rthe new MBP to be 64-bit, it should increase the speed quite dramatically right?

deadkenny said:but I'm quite sure that we'll never see 256bit. At least no one will ever find the need to adress 2^256bit of RAM ;-)
janstett said:Wrong wrong wrong, it doesn't work that way. In fact, being 64-bit just for the sake of being 64-bit can make things SLOWER.
If I ask you to add these two numbers:
000000000000000000000000000000001 +
000000000000000000000000000000010
It will take you less time than to add these two numbers:
0000000000000000000000000000000000000000000000000000000000000001 +
0000000000000000000000000000000000000000000000000000000000000010
The result is the same; which one can you add together faster?
Now, having said that, a switch to a 64-bit architecture usually also includes other generational improvements in design that will help cover that up and make it a positive experience but they have nothing to do with being 64-bit.
Worse, now you need an operating system that is 64-bit capable, and then that requires all new applications compiled for 64-bit mode and new drivers written in 64-bit mode, and then there's the problem of how do you run 32-bit applications?
The Windows world has been struggling with this for a few years now... The end result is that 64-bit XP is a toy that isn't ready for a mass market switch and people use their 64-bit chips to run the old 32-bit OS and apps.
