Pentium 4 at 2.53Ghz, 533Mhz bus
Normally, I could care less about the doings of the Intel bunch, but a 533 Mhz bus? I would love to see Apple/Mot/IBM make some strides here......
Exerpt From CNN.com
SANTA CLARA, California (Reuters) -- Intel Corp. Monday rolled out three new microprocessors, including the speediest Pentium 4 to date, keeping up the speed race against rival Advanced Micro Devices Inc.
In addition to a Pentium 4 chip running at 2.53 gigahertz, Intel, the world's largest chipmaker, also introduced a far faster bus, which connects the processor to memory chips in a personal computer. The faster bus moves bits at 533 megahertz compared with 400 megahertz previously.
In addition to improving the performance of PCs, the faster bus also makes more room for faster Pentium 4 chips. Intel executives have said its Pentium 4 chip, and the company will be selling a Pentium 4 chip running at 3 gigahertz in the fourth quarter. .....

[quote]Yesterday G4, 1Ghz on 133 bus with 133 ram.
Today G5, 1.2 Ghz on 400 bus with 266 ram
Today (5/4)*1.2*(400/133)*(266/133) = 800% faster than yesterday<hr></blockquote>
Think Fuzzy
Doesn't matter if this is meaningless. It's going to count to most people these days.
That's total bullshit, the bus runs at 133 respectively at 100MHz, but is quad pumped, ie send at the rising and falling edge of a clock cycle, with 2 cycles set apart 180° for an EFFECTIVE transfer rate of 533MHz and 400MHz.
Still it's impressive of course
As for the RAM: that aparently also only runs at half the speed, but is double pumped, ie not 1066MHz, but 2x533MHz.

IMHO, this is just a bunch of number-trumping...
Yeah I would be jealous of the Other Side with the numbers if not for the following fact:
JUST BECAUSE YOU ARE MOVING DATA FASTER, DOESN'T MEAN YOU ARE PROCESSING IT FASTER.
In other words, "woohoo, now we have the data bottlenecking at the processor 5 times as quickly!" Wouldn't it be nice if their CPUs could actually handle that speed...
Now, a 533Mhz bus on the 128 bit datapath of the G4... That would be nice... At least it would be able to handle the speed bump instead of looking longingly at all the promptly bottlenecked instructions...

the Next is DDR-RAM which uses a bus of either 100Mhz, 133Mhz, 166Mhz has just began being sold a month ago and 200Mhz was reveleaed but not released yet. Now DDR-RAM speed is actually the Bus x2, so when you hear DDR-RAM board with 266Mhz bus it means 133Mhz bus
now the 3rd which is RDRAM aka Rambus is the same as DDR-RAM but the Memory speed is the Bus x4, so the RDRAM that was sold until recently was 100Mhz system bus, and the new 533Mhz is actually 133Mhz bus. So the memory is faster but the bus is slower then DDR-RAM
as for SD-RAM it should be replaced

Ummm... No. RD-RAM and DDR are a lot more different than just douple vs quad pumped. This thread has a pretty good discussion about some of the differecnces. <a href="http://forums.appleinsider.com/cgi-bin/ultimatebb.cgi?ubb=get_topic&f=1&t=001623" target="_blank">http://forums.appleinsider.com/cgi-bin/ultimatebb.cgi?ubb=get_topic&f=1&t=001623</a>

I believe that's the purpose of the 2.5 GHz P4, to be bumped up to 3 GHz by the end of the year.
That's 3X the speed of a G4. Altivec cannot make up for that sort of speed difference.
Who fscking cares?
The fact, the simple fact is that the pentium 4 bus provides 4 times more bandwidth than the G4 memory bus and the memory it uses also has 4 times the bandwidth. That's what matters. Whether it's 4x133 or 1x533 is irrelevant.
It may make you feel better when you say "well, it's not really 4 times as fast as my Mac, it's just 133x4" but that's just it, go ahead and feel better, that don't change a thing.

<strong>One concept to consider: If Apple Computers wasn't the only company who produced Macs (which would result in more competition), maybe we wouldn't be so far behind in processor and bus speeds compared to say Intel? I'm not saying Apple is doing a poor job in terms of providing faster CPUs and so forth because I understand they are working as hard as they can on this issue. Just a thought...</strong><hr></blockquote>
The issue isn't competition so much as marketshare (or market size). One company with three times the current marketshare of Apple producing Macs would do a lot more for PowerPC than three companies producing the current marketshare of Apple.
More units sold => more money to Motorola => more money for R and D => faster processors
Intel isn't ahead because there are x zillion PC companies, but because the total size of those companies is so large.
I second your whimsy.
