Do I have these data rates right? Any other rates to add?

It seems the PCI system bus is becoming the big bottleneck these days;
so, how well the software utilizes the limited system bus and avoids
latencies may be the biggest speed factor. And where L2 and L3 caches
could be critical for certain apps.

Also, for typical HotSpots where the machines are all just talking to
the Internet, not to other machines within the HotSpot, is there any
real point to the 802.11g over 802.11b... given both are much faster
than the DSL or T1 connections to the Internet?

All in Mbps (not MB/s):

64000 => Power Mac G5's Frontside Bus
_8800 => PCI-X System Bus (used in new G5 Power Macs?)
_3000 => Serial-ATA II
_2000 => AGP 8X (used in G5 Power Macs)
_2000 => Fibre Channel (G5 connection to Xserve RAID)
_1340 => Ultra 160 SCSI (160MB/s)
_1200 => Serial ATA (150MB/s; used in G5 Power Macs)
_1064 => Ultra ATA/133 (133MB/s; used in G4 Power Macs)
_1064 => PCI System Bus (used in PowerBooks and Power Macs?)
_1000 => AGP 4X (used in PowerBooks)
_1000 => Gigabit Ethernet
__800 => Ultra ATA/100 (100MB/s; used in PowerBooks)
__800 => FireWire 800 (1394b)
__480 => USB 2.0
__400 => FireWire 400 (1394)
__160 => Ultra SCSI
__100 => Fast Enet
__100 => BlueTooth 2 (max; range 16-100)
___54 => Wi-Fi 802.11g
___40 => SCSI 1
___12 => USB 1.1
___11 => Wi-Fi 802.11b
___10 => Ethernet
___10 => DVD Video
____8 => EPP/ECP Parallel interface
____3 => BlueTooth 1.2 (max; range 2-3)
1.544 => T1
1.500 => DSL top typical rate (8Mbps theoretical top)
1.411 => Audio CD
1.000 => BlueTooth 1.1
1.000 => Centronics
0.800 => CDMA common
0.768 => DSL #2 typical rate
0.256 => ADB
0.200 => GRPS common
0.128 => ISDN
0.115 => Serial RS232 interface
0.072 => IrDA
0.056 => V.90/V.92 (though 0.024 common)

First, this is an informative table of relative speeds...thanks for providing it.

For the second part of your question, I would opt for the g spec network, given the nominal increase in price for that equipment.

I'm also thinking about your other post about building a commercial hot spot...in that context, it would seem the performance "headroom" provided by the g network would be helpful in answering (inevitable) client complaints about response time...:-) As you are probably aware, server and network latency on the Internet will have a far greater impact on the user experience than your local network (excepting, of course, RF signal anomalies that might exist in your space)...

Good luck with your implementation.

Oh, and you could add additional carrier transit data rates to your list...check out this list:

Nice work.
