1GHz FSB vs. 2GHz FSB

post #1 of 7
Thread Starter 
I've noticed that the fastest Mobos and CPUs on TigerDirect.com are 2GHz, but on newegg.com are 1GHz. The wierdest thing is that some of the stuff are similarly priced and seem pretty much identical except for the FSB.
See for yourself:


ECS nForce4-A939 Socket 939 ATX Motherboard:

TigerDirect.com - 2GHz:
http://www.tigerdirect.com/applicati...&sku=S458-1204
$79.99

newegg.com - 1GHz:
http://www.newegg.com/Product/Produc...82E16813135177
$73.50


AMD Athlon 64 3000+:

TigerDirect.com - 2GHz:
http://www.tigerdirect.com/applicati...?EdpNo=1366603
$139.99

newegg.com - 1GHz:
http://www.newegg.com/Product/Produc...82E16819103537
$141.00


Anyone know what's going on with this?

They're all 2000mhz, tigerdirect is just showing the actual DDR rate, newegg is showing one way (ddr=double data rate)

Umm, DDR has NOTHING to do with FSBs. DDR is ONLY related to RAM (Random Access Memory) and has to do with the fact that it communicates twice as fast as SDR or Single Data Rate. I am 90% certain there is no DDR Front Side Bus speed

Actually thats how you GET the bus rate...the ddr speed x the l2 cache...

The rate of the HTT in the AMD 64 series is the Hypertransport (or FSB) in Mhz x the HT Multiplier (Default settings are 200 x 5 =1000Mhz). This is a 2 way process, so runs at 2000 speed.
L2 cache isn't involved in this calculation and is a buffer between the RAM and the CPU to aid faster processing times.
