The Intel Core 2 Duo T8300 was at the time of announcement a fast dual-core CPU for laptops with 3 MB level 2 cache. It is based on the Penryn core with all features enabled (but without the full 6MB level 2 cache). The later announced Core 2 Duo P7450 was cheaper and used less power.
The Core 2 Duo SP9300 is a power efficient (25W TDP) dual core CPU for laptops. Compared to other Core 2 Duo with 2.26 GHz, the SP9300 features the full 6 MB level 2 cache of the Penryn core. Usually 3MB are enabled for 25 W CPUs at this clock range (e.g. P8400). Therefore, the performance is a bit better than similar clocked C2D CPUs.
The Intel Core 2 Duo T6400 is an entry level dual core processor for cheap laptops. It is based on the Penryn core but offers only 2 MB level 2 cache and a slow clock speed of 2 GHz. The performance should be sufficient for office and other casual tasks but high level gaming and HD video editing for example could be limited by the CPU performance.
