3750G vrs 3560E What's the real difference?

I'm having a hard time seeing what difference there is between the 3560E series and the 3750G series switches. They seem very similar. Can anyone enlighten me on technical specifics of how they differ? TIA!

Re: 3750G vrs 3560E What's the real difference?

The 3750's are stackable allowing them to be managed as one switch similar to a chassis based switch.

Cisco StackWise Technology offers Stackable Resiliency

Cisco StackWise technology is a stacking architecture optimized for Gigabit Ethernet. This technology is designed to respond to additions, deletions, and redeployment while maintaining constant performance. Cisco StackWise technology unites up to nine individual switches into a single logical unit, using special stack-interconnect cables and stacking software. The individual switches can be any combination of Cisco Catalyst 3750 and Cisco Catalyst 3750-E Series Switches. The stack behaves as a single switching unit that is managed by a master switch, elected from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables. A working stack can accept new members or delete old ones without service interruption.

Data Sheet 3650 and 3750.

I think the main difference, other than the stacking element mentioned, is that the 3560E series support the X2 10GE modules where the 3750G's (with the exception of the 16TD) only accept SFPs.

Re: 3750G vrs 3560E What's the real difference?

The 3560E offers both 10 gig (as mentioned by another poster) and a fabric bandwidth and PPS forwarding performance to practically support line-rate/wire-speed on all ports. The 3750G can be physically "stacked" with other 3570 series switches, including the "E" series, but it also provides much less fabric bandwidth and/or PPS forwarding performance.

PS:

BTW, for most purposes the 3560 and 3750 series are alike except for the latter's stacking capabilty. Ditto for the 3560E and 3750E series. The non-E series vs. E series differ mainly with regard to high capacity performance. The 3750E series also offers 2x the stack bandwidth of the non-E 3750 series, and further, the former is "smarter" in how it uses its stack (StackWise vs. StackWise+; also see https://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps5023/prod_white_paper09186a00801b096a_ps7077_Products_White_Paper.html).
