I read an article about Front Side Bus of AMD chips and have a question:
How does the FSB of an AMD CPU compare to that of the Pentium CPU?

From what I read, the 3200 CPU has a FSB of 400, but it doubles because it sends 2 signals...?

so is the FSB of the AMD better, or the same as Pentium?

thanks!

Technically the Athlon 64 doesn't have or use a FSB. The Pentium uses the FSB for accessing the memory and communicating with the rest of the system, the Athlon 64 uses it's own on chip memory controller and uses the hypertransport to communicate with the rest of the system. Since they work in different ways and for different purposes comparing the two is not really useful.

In other words it's like comparing an apple to a grapefruit.

What you are interested in is the memory bandwidth, because this is the only point at which an "FSB" has any bearing between the two.

In AMD's favour is the on-die memory controller of the Athlon64. This makes AMD processors wait less for data, hence higher scores in memory intensive applications.

Raising the Hypertransport speed has the same effect on memory bandwidth as raising the FSB on an Intel platform - except that raising the Hypertransport speed does *NOT* raise the CPU speed. Very handy for Overclocking!

All in all, it seems AMD has the edge in memory management right now. Good time to buy.

I recently built an Intel 915, 3.4 GHZ P4 system, 2 Gig Ram, X600, using 2x Seagate 7200 RPM, 200 GB SATA drives (~ $150.00 CAD ea.) in a Raid 0 array. Its one fast desktop, CAD opens very, very, large files (6x 25-60 MB files) no problem.

HD tach 3 put the average speed of the transfer rates at 2/3 that of an Ultra 320 SCSI drive, I got consistent transfer rates of over 100 Meg/sec...

An 150 GB Ultra 320 SCSI drive is ~ $810 CAD ea.
I'll take 2/3 performance at the cheaper price point.

Also Intel has Matrix Raid it's a good performer as well and performs just slightly slower than real RAID.

Was Canuck's reply meant for a different thread or something?

thats what im wondering

How about the wrong bb

Too many windows open and too much cutting and pasting going on.

HEH! I wonder what you posted in the other forum.

LoL!

well, thanks for the replys!

I'll hijack my own thread here and ask yet one more question on my upgrade/new system:

If the DFI SLI mb has a 24 pin connector, and the fortron blue PSU has a 20 pin connector, even though it comes with a 20 to 24 adapter, is there another PSU out there that has 24 pins so I dont have to mess with the adapter?

Huge price premium for it, but that's the only thing that kept me from getting that PSU.

This one is also very good and has a creative way of helping with the cable management, worth checking out anyway.

yeah the OCZ is my next bet, but it's $30 more sheesh. the PSU is almost as much as the mb....

thanks tho.

Is thermaltake a decent PSU company?

One of the nick names for thermaltake is thermalmistake if that give you an idea.
I would never use one, the only brands I would use for my own system are Forton, OCZ, Antec, PCP&C, and Enermax.

The fortron's are 24 pin with an adaptor to convert to 20 pin. YOu have it backwards

Thanks Stress!
I searched the whole description at newegg for anything about pins, but couldnt find a thing....

So are the DFI lanparty boards 24pin as well?

The Nforce 4 DFI foards are 24 pin.

I think they can also use a ATX 12v powersupply by plugging in the 20 pin connector and the 4 pin auxilary conector next to it. Someone else might know for sure.

Probably not.



If it is a 24pin bpard (I dont know because I dont use DFI) and the Forton Blue Storm PSU's are 24 pin, what is the discussion?

Is it just me, or am I retarded?

I shouldn't steal bandwidth from websites because it's bad and I am a bad boy..

Dunno where you got those pin outs, but people are using 20 pin PSUs to power 24 pin boards. Both with and without the converters.

The sub thread Radical linked to goes into more detail.

The same place he is stealing the bandwidth from, pcguide.com

The top picture is from a SFX Form Factor main board.

The bottom picture is the P1 connector on a WTX Form Factor main board. But then on WTX you also need a 22 pin P2 connector and can have P3-P5 connectors.

EDIT: Sorry the top picture is ATX not SFX as I said.

Hey, it's KompresZor. When's the most easy going player gonna be back in DC?
