FINALLY!
YOUR ONE STOP REFERENCE SPOT FOR ALL THINGS
THROUGHPUT/BANDWIDTH/DATA TRANSFER RATES
(WHATEVER YOU WANT TO CALL IT) ON YOUR PC!
All speeds are listed in MegaBytes/per second so as to easlily make comparisons.
CARD-BASED INTERFACES
PCI STANDARD BUS (thought to be the main bottleneck of the modern PC):
PCI 33mhz 133 MB/s
PCI 66mhz 266 MB/s
PCI-X BUS (mainly found in servers):
Accelerated Graphics Port or AGP (video card interface):
1x 266 MB/s
2x 533 MB/s
4x 1,024 MB/s
8x 2,048 MB/s
PCI-Express (introduced in Retail Desktop Motherboards 2nd Quarter 2004):
X1 250/500 MB/s
X4 500/1,000 MB/s
X8 1,000/2,000 MB/s
X16 (replacing AGP 8x) 2,000/4,000 MB/s
DISC BASED I/O (NOTE - RAID configurations will increase throughput)
PARALELL ATA:
ATA/IDE ? MB/s
ATA/E-IDE/UDMA-0 16.7 MB/s
Ultra-ATA/UDMA-1-2/ATA-33 25/33 MB/s
ATA-66/UDMA-3-4 44/66 MB/s
ATA-100/UDMA-5 100 MB/s
ATA-133/?UDMA-6? 133 MB/s
SERIAL ATA:
Generation 1 150 MB/s
Generation 2 (future) 300 MB/s
Generation 3 (future) 600 MB/s
SCSI:
SCSI-1 5 MB/s
SCSI-2 Fast 10 MB/s
SCSI-2 Fast/Wide 20 MB/s
SCSI-Ultra 20 MB/s
SCSI-Ultra Wide 40 MB/s
TRANSFER CONNECTIONS
USB:
1394 (A.K.A. Firewire/i.Link/Lynx):
1394A 50 MB/s
1394B 100 MB/s
NETWORKING
ETHERNET:
Standard 1.25 MB/s (10 megabit)
FAST 12.5 MB/s (100 megabit)
Gigabit 125 MB/s (1000 megabit)
OTHER STATISTICS OF NOTE
HARD DRIVE - Max sustained transfer rate seems to be around 55 MB/s
MEMORY - Current max DDR2 Memory Clock Speed(mhz) is 533mhz (68,000 MB/s,or 8.5GB/s, of memory bandwidth).
FRONT-SIDE-BUS (FSB) - Current max FSB speed is 2ghz(2000mhz) on the Intel and AMD systems.
CD/DVD ROM & BURNER DRIVES - a 52x CD transfers/burns at 7.8 MB/s and can read/burn a full CD in little over 1 minute. A 16x DVD transfers/burns at 21 MB/s and can read/burn a full 4.5GB DVD in about 3 minutes 15 seconds.
