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."

Re:i850E doesn't officially support PC1066 RDRAM

[questionlp]

I forgot to make a comment about the AMD T-bred processors. Why doesn't AMD start putting some type of protection on the naked cores? I would really like to see AMD to put on the integrated heat spreaders on the processors to help reduce the chance of cracked and broken cores, as well as help dissipate the heat from the now smaller cores.

Sure, the T-bred processors won't be producing as much heat (due to the die shrink), but once speeds start hitting well over 2Ghz, I expect the cores to get very, very hot again.

Just my $0.015 post-taxes.

this is no biggy

who cares what the FSB is at this stage. untill we have SDRAM that supports this "bandwidth" it will not help out total system performence.

It gets worse...

[Anonymous Coward]

Why does Intel boost the FSB speed and then turn around and bork it with old crap on the southbridge?

Specifically:
ICH2 South Bridge connected to the MCH via Hub Link 1.0 with 266MB/sec bandwidth;
AND
ATA/100, USB 1.1 and AC'97 sound support.

ATA/133 and USB 2.0 are pretty much the standard now on Socket A motherboards.

Intel killed this motherboard line before it was even made...

What kind of RAM?

[Lord Ender]

Buying RAM is a bit confusing now. Athlons have 200MHz FSB and 266MHz FSB. What kind of DDR should I use with each? There is DDR1600, DDR2100, DDR333, and some other stuff. Now there is this intel chip with 533MHz FSB. Is there an easy rule to remember what number after the 'DDR' coresponds with the number before the 'FSB'?

It gets so confusing, building your own systems is becoming less appealing.
