Intel Moves To 533MHz FSB
homerj79 writes: "Intel has launched an upgrade 850 chipset and faster Pentium 4's today. The new chipset, dubbed the 850E, supports a 533MHz (133MHz x 4) front side bus, as do the processors. Supporting processors come in speeds of 2.53, 2.4 and 2.26GHz. The 2.4GHz part is denoted as supporting the new FSB by a 'B' tagged to the end of it. And it appears as if the new chipset gives the P4 a performance boost in most apps over the previous 400MHz FSB chips and the Athlon XP." Meanwhile, back at the other processor ranch, firemoth writes: "Today OCAU has something special - They've gotten their hands on 3 AthlonXP
CPU's based on AMD's new "Thoroughbred" core. This is the .13 micron
process, of course, with lower voltage. This article compares them to the
older Palomino core in both speed and temperature.. and they throw one into a
Vapochill supercooling case and see just how fast it can go."
Although quite a few Samsung PC800 modules will run at PC1066 speeds without any problems, but if any installed modules are not capable of running at the higher speed, the memory bus will get capped at the current max of 400Mhz (or 3.2GB/s).
I guess for now, the new processors don't really, really need the higher memory bandwidth, but as the processor speeds start to hit 3+ Ghz, the extra amount of bandwidth will become more important.
Can't believe that Intel isn't supporting the ICH4 with the i850 (ICH4 adds USB 2.0 support among other things.) This is reported at Tom's Hardware I believe. Intel's ass backwords manner of support for PC1066 RDRAM stinks too.
So when are i845E boards coming out? Why didn't Intel announce that and the i845G today? Probably some stupid contractual thing with Rambus I suppose.
Sure do hate it when marketing and politics overrule good engineering. Intel should be building ATA-133 and Firewire/IEEE1394 support into their chipsets as well. And the i845E should have support for DDR300.
What a bunch of losers.
So Intel put the P4 on a quad-pumped bus to get the clock speed to look better. When AMD put the Athlon on a double-pumped 133 MHz bus and said it had a 266 MHz bus speed, nobody believed it. Now even Socket A motherboards admit that they run at 133 MHz now. What gives with Intel doing this? Am I missing something that's supposed to impress me?
(if I am, please tell me, because otherwise I will be buying an AMD processor for my new computer)
Are there any reviews or benchmarks available for the new CPUs using 266MHz DDR memory? It looks like RDRAM is not the most popular memory, but Intel is only allowing reviews that use RDRAM and not DDR. Onquiring minds want to know how a normal P4 config compares to a normal Athlon config.
clock speed != performance
write that 1000 times
if AMD has to fudge numbers to sell an equivalent product, that's the fault of the largely ignorant market, not AMD.
read any of their literature, they're very honest and upfront about what they're doing.
In Capitalist America, bank robs you!
Yeah, I don't know either. I work with 802.11b stuff a fair amount, but I'm no R/F engineer. Still, I can't help but imagine this becoming an all to common occurence:
D: Greetings, Dell tech support.
A: Hi, this new desktop you sold me is junk.
D: What model is it?
A: The new 2.4GHz P4, with the integrated wireless ethernet and wireless bluetooth keyboard.
D: And what seems to be the problem?
A: Every time I try to make a call on my 2.4GHz cordless phone, the computer crashes! And when I surf the web, my phone rings! And everything I type is ending up in my Palm's ToDo list! Then while I was upstairs heating my coffee in the microwave, it caught on fire!
I mean really, how much stuff can we possibly cram into the 2.4GHz band anyway? Interesting times anyway.
When the Thoroughbred core CPUs starting cranking up the clock speeds then even the fastest P4 will have to look up. The P4s were benchmarked with RDRAM motherboards which aren't available yet but will be here soon. If you want a fast system that is here now then get the Athlon or spend some more money and get a P4 that is going to be close to the same performance.
When, do you think, will we see processors with the main memory built in? I mean you may as well stuff it when you get it, it'll make it cheaper because we'll all get the same thing. Or is that just too far fetched an idea? ie. The new 2.5GHz with 4GB RAM right on the CPU. Hunh? Maybe it'll get rid of all this crap surrounding buying or trying to match RAM to...whatever!!!!
