I did a search and couldn't find anything worthwhile. Question: What's with the 800MHZ FSB that Intel seems to have? Granted, it's not slow, it's just that no matter if it's a 1.6G or 3.6G system, it never seems to get past that. I'm not trying to start a "Thing" here, but would really like some info.

It's actually what they term "quad-pumped" at 200 MHz FSB.

Their P4 Extreme Editions are at 1066MHz, quad-pumped.

This is not only one of the worst analogies I've ever seen posted, it's not even close to the way OS schedulers work.

A single thread cannot be "spread" across more than one core simultaneously - it can only be scheduled on one CPU at a time. The other CPUs (cores) can be scheduled with other threads from other single threaded applications, without any CPU level contention. (Disks, network and memory contention may be happening - but your description of one thread clogging all the cores is absurd.)

Thanks for clearing that up. I was going to if you hadn't. 1 thread/core, or 1 process/core, or more of course via scheduling, but .5 threads/core doesn't make any sense.
 
Where have I been?

It's very interesting to find out what benchmarks show up as or even
what they vary between versions. My G5 2.5 dual produces an utterly
absurd 312 rating in an old version of Xbench I have lying around but
produces 126 or so on the latest. I also find I get better results when
the network cable is UNPLUGGED when running Xbench scans.

And here's something I found very interesting. I used ATIccelerator II
to overclock my 9600 XT video card in my G5 2.5 dual and found that
with all the new Quartz Extreme features it had an effect on the outcome
of the tests.

The 9600 XT comes shipped with the Mac is clocked to 400 mhz with
the memory somewhere in the low 300 range whereas the same card
on the PC is clocked to 500 mhz with memory in the 320 range.

PC overclockers have determined this card can easily be pushed 25%
beyond original rated clock (original being 500) but don't push the
memory beyond 330 or you could have a dead card on your hands.

So I decided to overclock the card and see how it effected some
game play and general use. A slight improvement. Original ratings
were 341, 970 and 1619 for the OpenGL shading portions of the
test. I set the card to 525 mhz clock and 322 mhz ram speed.

Check this:

Interesting. A bit of extra speed but one suspects Apple clocked the
cards to 400 mhz so as to not necessitate a fan on the cards thus
keeping it quieter than a fanned card. I've since brought it back to
the original clock speed but when playing games or the like I'll bring
it back up there.

Food for thought. /Re-enter lurk mode.

Using Photoshop CS or CS2 (or PS 7)
==================================================
1.) Download the test image from http://www.quicklance.com/test.jpg
2.) Save it to the computer and then open it up in Photoshop
3.) From there please apply a ‘radial blur’ with the settings at:
Amount = 100
Blur Method = Spin
Quality = Best
Using a stop watch / ps timer see how long it takes to apply this filter
I just want to see what these new cpu’s can really do.

Results:
iMac G5 1.8GHz, 1GB - 2:00
Athlon XP3200+, 1GB - 2:15

Quad 2.5GHz G5 2.5GB RAM 10.4.3 22 seconds !!!!! It's an amazing huh??!!!


Took 2:35 min on my Mac Mini 1.42 with 512 mb ram.. i'll re-run the test and confirm

Edit: This time it took 2:32... I love this li'l pest :D
 
new quad benchmarks

Macrumors said:


One of our Wales UK-based members has reported receiving his Power Mac G5 Quad earlier in the week, and has run a preliminary set of Xbench benchmarks on it. While full details are in the forum thread, the overall score for the machine with 3 GB RAM running Mac OS X 10.4.2 weighs in at 151.86.

Compares quad to dual core 2.5 i believe.... enjoy
 
Pie said:
Does this make any sense to anybody?
Yeah. My old 800 MHz G4 PowerBook gets a 72 for rendering, and IIRC my dual 2.0 G5 gets something around 550-600...so your 1016 looks pretty good, considering the overhead of multithreading. :)

Your point , Do u think most system builders paid $300 for XP Pro. I've seen more cracked XP Pro Discs passed around then AOL sign up discs. The Pirates are going to Increase OSX's market share more than anyone in the coming years.

Arrrr Matey there be cracked Tigers in the Bay (Hint Hint).:D

It wasn't hard to crack the security for XP because it was a halfhearted attempt.

Tiger depends upon much secure technology. The software code is tied to the hardware. It's not likely that it will be so easily cracked. Even if it is, the technology assures that no programs will work.

Having the OS with nothing to run on it will be a lot of fun.

How does the Quad compare to this:
http://www.torrentspy.com/article.asp?id=3805

The US National Nuclear Security Administration (NNSA) has unveiled two new IBM supercomputers at Lawrence Livermore National Laboratory (LLNL), which are capable of the fastest processing speeds yet achieved.
The 65,536 processor BlueGene/L supercomputer has performed a record 280.6 trillion operations per second on the industry standard LINPACK benchmark - software used to rank the speeds of the world’s fastest machines.

Purple, the other half of the most powerful supercomputing twosome, is a machine capable of 100 trillion operations per second as it conducts simulations of a complete nuclear weapons performance.
Together, the Purple and BlueGene/L systems will perform half a petaflop, or half of a quadrillion (1,000,000,000,000,000) operations per second.
NNSA administrator Linton F Brooks said the machines will be used to run three-dimensional codes at lightning-fast speeds for nuclear weapons’ analysis. This was formerly accomplished by underground nuclear testing.
“The unprecedented computing power of these two supercomputers is more critical than ever to meet the time-urgent issues related to maintaining our nation’s aging nuclear stockpile without testing,” Brooks said.
“Purple represents the culmination of a 10-year effort to create a new class of supercomputers. BlueGene/L points the way to the future and the computing power we will need to improve our ability to predict the behaviour of the stockpile as it continues to age. This has reestablished American computing preeminence.”

In a recent demonstration of its work capability, BlueGene/L ran a record-setting materials science application at 101.5 teraflops sustained over seven hours on the machine’s 131,072 processors, running an application of importance to NNSA’s effort to ensure the safety and reliability of the nation’s nuclear deterrent. A teraflop is one trillion computer operations per second.
Both machines were developed through NNSA’s Advanced Simulation and Computing (ASC) program and join a series of other supercomputers at Sandia and Los Alamos national laboratories that are dedicated to NNSA’s Stockpile Stewardship effort to maintain the nation’s nuclear deterrent through science-based computation, theory and experiment.

Windows will also do it automatically, and probably better than you can do it by hand unless you have a pretty unique and static workload.

Setting affinity manually often leads to one core sitting idle while multiple threads are fighting for the other core.

I thought so as well, but you know, with Windows I have said too often, 'But that cannot be' only be told later, 'No, that's the way Windows works'.

strange that link has at the bottom 16GB of ram with just 6 slots; how on Earth are the configuration for the RAM chips?!!
16GB, DDR2 SDRAM Memory, 400MHz, ECC (6 DIMMS) [add $23,300]

Easy - two 4 GiB DIMMs, and 4 2 GiB DIMMs.... (note that 12 GiB is only $9.2K)

For the first time in Apple's history we are looking at a regression in chip technology over the next year from this point on - assuming Intel can even get something usable out next year.

Massively cheaper and faster quad systems and it is all being thrown out the door. Thank you Jobs you idiot. Go play with your iPods and find someone competent to run the desktop hardware side of the company.

It is going to be embarrassing to have to listen to him try to spin his was through the performance and feature drop that will come when the first garbage Intel desktops show up. Sickening.
I don't know what you're smoking, but from where I sit I see nothing but faster PowerMacs etc coming down the pike. Nothing is being thrown out any doors that I can see. :rolleyes:

If a man makes it another can break it , this is fact. There are ways to fool software to believe you are running it's certified hardware. all of a sudden because it's made by apple it won't be hacked, cracked , and distributed all over the web. News Flash buddy I can download Tiger 10.4.3 right now for mac or PC and both will work just as good as your copy. You continue to believe the crap Jobs feeds you. and i will be here to gloat this time next year.
