PC Faster than Mac ???
Heard many times from the stormtroppers of the darkside that PC is faster than Mac.......
I am also a believer that Mac is faster in Digital Image/Video Processing.
Any Comments on the article below?

Look at Xserve benchmarks to see what potential DDR can make even when not implemented fully.
It's time for new PMs (faster bus and CPU).
PS: It will be interesting to see a benchmark with the XServe.
<strong>Some have said that the XServe benchmarks benefited heavily from independent ATA channels. If we're talking about operations that aren't disk heavy, might DDR not be the PM's savior?</strong><hr></blockquote>
I would see independant ATA channels as leveling the playing field with the competition using SCSI. I do think that the Xserve ATA system helps and it'd be great to see something like that in the next Powermacs.
Since ATA draw a little CPU power, it is crucial for a server to have this independent, also for other reasons.
But I also dont think getting DDR creates a "wonder" here!
Apple should at least start to add the maximum of supported L3 cache, and here I dont care if this costs a little. If I compare my Ti800 to my QS867 (no L3), the Ti "seems" faster, despite the fact its a Lowpower G4 version of trhe 7455 used in the QuickSilver.
The upcoming MPC7470 is supposed to support 4 MB DDR Cache, and I urge Apple to fill it up with 4 MB.
I certainly dont udnerstand why they stopped making such beasts like the Mac IIfx or the Quadra 840av. It least here in Switzerland these machines sold very well, althought they were, uhm, quite expensive.
Why dont they do this anymore? Just mainstream Macs, a few singles, a top end dual, slightly more Mhz if at all. No fast harddrives, etc.
Its time Apple shows they can design Hardware. Many commercial agencies and design studios will buy the last bit of performance!
At least the TiBook kicks most PC laptops ass, if not, take in the price as well *ggg*
I'm really worried about how much of an effect DDR will have on the G4. RISC proccessors don't necessarily need that kind of memory bandwidth that x86 processors use. Also, without a faster memory bus, it won't do much good. For example, i have a P3 DDR system and a P3 SDR system. Both of them perform about equally in real world applications. The p3 is based off of a 100 and 133mhz bus, and doesn't need/can't make good use of the added memory bandwidth.
We shall see however, when comprehensive benchmarks are made between the SDR and DDR platforms
Back in the pentium days Toms Hardwareguide showed that 166 MHz Pentiums ( with a 83 MHz bus) were faster than 200 MHz pentiums with a 66 MHz bus. On the Mac side the 601 and 604 scaled better with busratios of 1:3 and even higher
So if a 133 MHz bus strangle a AMD or a Intel CPU running on a 20X bus multiplier that does not mean that a G4 133 MHz Bus and 7.5 multiplier is strangled.
Perhaps it is even affected my the OS?
Is there any test made on Linux and Win to see if the performance hits are the same on different OSes?
<strong>.......PC is faster than Mac.......
</strong><hr></blockquote>
True
<strong>The current Powermacs are indeed bottlenecked by the memory subsystem. I agree the Athlon and the P4 require fast memory busses but so does the G4. We haven't seen what the G4 can do without limitations. I'm looking forward to finding out.</strong><hr></blockquote>
hear! hear! I'll drink to that.
Now if Motorola would only do their part....
