List of Intel Core 2 microprocessors

The Core 2 brand refers to Intel's x86 and x86-64 microprocessors with the Core microarchitecture made for the consumer and business markets (except servers) above Pentium. The Core 2 solo branch covered single-core CPUs for notebook computers, Core 2 Duo – dual-core CPUs for desktop and notebook computers, Core 2 Quad – quad-core CPUs for desktop and notebook computers, and Core 2 Extreme – dual-core and quad-core CPUs for desktop and notebook computers.
Desktop processors.
Dual-Core Desktop processors.
Core 2 Duo.
"Allendale" (65 nm, 800 MT/s).
Note: The M0 and G0 Steppings have better optimizations to lower idle power consumption from 12W to 8W.
Note: The E4700 uses G0 Stepping which makes it a Conroe CPU. 
"Conroe" (65 nm, 1066 MT/s).
Note: of the E6000 series processors, only models E6550, E6750, and E6850 support Intel's Trusted Execution Technology (TXT).
Note: The L2 Stepping, and models with sSpec SL9ZL, SL9ZF, SLA4U, SLA4T, have better optimizations to lower idle power consumption from 22W to 12W.
Note: The M0 and G0 Steppings have better optimizations to lower idle power consumption from 12W to 8W.
"Conroe" (65 nm, 1333 MT/s).
Note: of the E6000 series processors, only models E6550, E6750, and E6850 support Intel's Trusted Execution Technology (TXT).
Note: The L2 Stepping, and models with sSpec SL9ZL, SL9ZF, SLA4U, SLA4T, have better optimizations to lower idle power consumption from 22W to 12W.
Note: The M0 and G0 Steppings have better optimizations to lower idle power consumption from 12W to 8W.
"Wolfdale" (45 nm, 1333 MT/s).
Note: The E8190 and E8290 do not support Intel VT-d.
See also: Versions of the same Wolfdale core in an LGA 771 are available under the Dual-Core Xeon brand.
Core 2 Extreme.
"Conroe XE" (65 nm).
"These models feature an unlocked clock multiplier"

Dual-Core Notebook processors.
Core 2 Duo.
"Merom", "Merom-2M" (standard-voltage, 65 nm).
See also: Versions of the same Merom-2M core with half the L2 cache disabled are available under the Pentium Dual-Core brand.
"Penryn", "Penryn-3M" (standard-voltage, 45 nm).
Note that models T8100, T8300, T9300, T9500 are Penryn processors designed for Santa Rosa Refresh platforms with maximum FSB of 800 MT/s, whereas the rest of the Penryn processors are designed for Montevina platforms that can go up to maximum FSB of 1066 MT/s.
Penryn processors support Dynamic Front Side Bus Throttling between 400–800MT/s.
Core 2 Extreme.
