Intel Core Duo is a family of dual-core mobile processors based on
enhanced mobile (Pentium M) micro-architecture. Core Duo processors
integrate two improved Pentium M cores on the die. While each core has
own 32 KB level 1 instructions and data caches, both cores share the
same 2 MB level cache. Like the Pentium M processors, the Core Duo
CPUs support SSE and SSE2 instructions, and include execute-disable
bit feature. New features in Core Duo microprocessors are SSE3
instruction set and Virtualization technology.

All low-voltage Core Duo and Core Solo microprocessors have model numbers starting from "L" rather than "T". The last three digits in the model numbers of these CPUs (these digits signify processor's relative performance) are not comparable with standard-voltage processors. For instance, this L2400 CPU runs at lower frequency and has lower performance than T2400 microprocessors.

Standard-voltage Core Duo microprocessors were offered with 533 MHz and 667 MHz Front Side Bus frequencies. Telling them apart by processor number is easy. All CPUs with "Tx00" processor numbers had 667 MHz FSB, and microprocessors with 533 FSB had "Tx50" processor numbers. Performance of processors with 533 MHz FSB in comparison with 667 FSB models was very dependent on the type of application. It could be the same or only a few percent slower in small, mostly CPU-intensive applications, or up to 35% slower in bandwidth-intensive tasks. As an example, this Core Duo T2250 with operating frequency 1.73 GHz and 533 MHz FSB is about 4% faster in Sandra synthetic benchmarks than T2300 with 1.67 GHz core frequency. Performance difference can be primarily attributed to 4% higher frequency of the T2250, and the fact that the Sandra benchmarks are not dependent on available memory bandwidth. The picture changes in WinRAR test, that relies heavily on memory bandwidth. In the WinRAR test the T2300 with faster FSB gets 30% better results than the T2250.

Many standard-voltage Core Duo and Solo CPUs are offered in two packages: 478-pin micro FC-PGA and 479-ball micro FC-BGA. All micro FC-BGA microprocessors do not use sockets. These microprocessors are soldered on the motherboards - as such, there is no easy way to replace or upgrade them. Fortunately, many notebooks use socketed micro FC-PGA processors - replacement of these processors is easy, although getting access to the CPU and CPU socket in some notebooks may be cumbersome.

T2060 not documented in here
Hi there, I come across a core duo T2060 1.6GHz with L2 = 1Mb lately, don't see it in here, so want to check real quick, thanks!
