What the Core 2 Duo E8235 is
The Intel Core 2 Duo E8235 is a dual core Penryn mobile processor from March 2009. It runs two Penryn cores at 2.8 GHz with no turbo and no Hyper-Threading, so 2 cores give 2 threads. Cache is 6 MB of shared L2 on a 45 nm process. Power is rated at 44 W with a 1066 MT/s front side bus.
The E8235 sits between the E8135 and E8335 in the vendor line. Against the P9700 it matches clocks with 6 MB of cache at higher 44 W power.
There is no graphics on the CPU. Display comes from the mobile chipset.
Socket and motherboard compatibility
The Core 2 Duo E8235 fits Socket P with 478 pins. Vendor boards boot it with a 2009 BIOS.
The Socket vs chipset: what decides whether a CPU works guide covers pairing rules, and the Intel Pentium Dual-Core T4500 page shows a Pentium on the same socket.
Memory, PCIe and cooling
Memory is DDR2 or DDR3 in two channels depending on the chipset.
The 1066 MT/s front side bus links the CPU to the chipset. PCIe slots hang off the chipset.
Cooling uses the notebook vendor assembly rated for 44 W.
Upgrade paths
On Socket P the upgrade is the E8335 or E8435 on the same board. Beyond Socket P a move to Arrandale needs a new notebook.
