Apple's Mac Pro has an undocumented feature: it runs eight physical processors without breaking a sweat

My former boss Anand Shimpi arguably has the best hack all week.  Shimpi managed to get his Mac Pro to recognize two quad-core Clovertown processors (running at 2.4GHz per core) in a single Mac Pro -- the resulting system ran flawlessly on eight processor cores.

No BIOS updates, no pin-hacks or anything exotic was needed to get the yet unannounced processors to work in the Mac Pro.  Shimpi adds "We can't say with 100% certainty that you will be able to upgrade to Clovertown when it comes out, but so far the results are looking good."

The Mac Pro is unique in the fact that the system uses server processors as opposed to desktop processors.  The Socket 771 Xeons used in existing Mac Pros, dubbed Woodcrest, support FB-DIMM memory -- the desktop variants do not. 

Intel has publically announced several times that quad-core desktop and server processors would be shipping from the company before the end of the year.  The desktop versions of the processors, dubbed Kentsfield, will carry the Core 2 Extreme brand.  The server brand, codenamed Clovertown, has not been announced yet. 

The Kentsfield desktop quad-core processor is expected to launch at a steep $999 MSRP, and typically server components from Intel MSRP for about 20% more than the desktop variants.

Didn't Anand also find that performance fell only 4% when one of the processors was disabled? It doesn't look like the Mac Pro can properly feed 4 cores right now, let alone 8.

No problem: Distributed computing would satisfy as many cores as can be served. This would be sweet for any DC-project!
BOINC works in Macs perfectly well (I have four of them running it), utilises any and all CPUs it finds and crunches - in a MacPro with 8 cores - 8 workunits simultaneously - at 100% load.

Amen. Start working with 4 day render times across 7 workstations and you'll appreciate the improvements of quad core.

All the software that will be enabled by the additional power this provide.

Think of it this way, Video enditing/encoding, audio manipulation/ 3D gaming was all enabled by increases in computer power. The power came first, then then applications.

The practicality and optimization for current software or OS platforms are one thing, but I think its good to get excited about technology moving forward (or in this case, outward?). We were stuck with glorified P4s and A64s for too long. I'm digging all these new releases. Plus, If a higher # of cores become the standard, more people will feel compelled (for whatever reason) to upgrade from their single core, and we'll see software written for multi-cores come out sooner and more often.

Umm,

My raidosity rendering scales quite well from 4 to 8 cores. I should know, I've done it.

Apple running dual Intel Xeon quad core processors with XP installed, dual-link DVI 30" Apple Cinema display. Wow. Zoom! Zoom! Nice machine. One button mouse, iTunes? What a larf. It's time Apple innovated a new controller, and developed some non-proprietary "productivity" software. That would earn them some kudos in the corporate market and really excite the brand.

Apple lives on its proprietarity. That's the only reason they were not completely crushed by bigger comodity vendors like Dell.

Ok, so why did I go from Windoze, and back to mac? I must be a stupid c*nt then...

Fact is: Macs are nice computers, and there's plenty of non-propreitary software for it...

What you're saying is basically that no one would choose Mac over Windows if they were presented with the choice, having never used either one... I fail to see your logic as I know plenty of people switching the other way these days, and I know people who have never had a computer who've chosen a Mac because it's a more appealing solution for them.

All I've ever wanted in this debate (Mac vs. PC) is mutual respect. I am totally fine with people using Windows. As long as they don't bash me for using something different, or call me stupid for having made a different choice. We all have different needs and feelings with regards to computers, and I don't see any reason why both platforms can't live peacefully in the same market.

Apple has a multi-button mouse out... The Mighty Mouse. It ships with new computers.

But I personally just use an MX1000, and I have never really liked ANY of the mice that come standard with Dells, HP, Apple, etc.
I bet a lot of professionals go out and find their own mouse, regardless what came with the computer. Be it a Mac or a PC.

I dont disagree with you! But my point was not about the mouse but rather that Apple is not innovating technology or function. They are just the "packaging" gurus. This is a shame: the organisation has a lot of potential for other innovation which could earn them, in the long run, a strategic win.


Clovertown is based on Xeon

Clovertown is based on Xeon, which is based on Netburst, correct?

I'd rather have two SMP-capable Core x Duo's instead.

Xeon is just a brand, its not limited to netburst technology.

The first Xeons I heard about were the Pentium II Xeons (or maybe the Pentium !!! Xeons).

in other words, Clovertown is the server version of Core 2 Quad, aka quad-core Conroe.

As the first reply said, Xeon is just a brand. It goes back to Pentium II days.



AMD quad-cores

and AMD quads will be recognised as one core, so they are gonna be alot faster running normal apps.

Mmmmmmmm. Care to explain this? Just spent some time searching around and I've found no reference to this kind of chip logic being built into the Quad Core AMD chips. Got a link?

LOL. AMD fans are getting delirious. I expect mass suicide in the next few months as Vista beings to ship.
