What the Core 2 Duo E8335 is
The Intel Core 2 Duo E8335 is a dual core Penryn mobile processor from March 2009. It runs two Penryn cores at 2.933 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 E8x35 line covers odd Socket P bins for large vendors at 44 W. One family table shows the E8335 at 2667 MHz against the task list at 2933 MHz, which is noted below as a conflict. Against the E8235 it leads on clocks at the same 44 W.
There is no graphics on the CPU. Display comes from the mobile chipset.
Socket and motherboard compatibility
The Core 2 Duo E8335 fits Socket P with 478 pins. Vendor boards boot it with a 2009 BIOS that lists the stepping.
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 E8435 on the same board. Beyond Socket P a move to Arrandale needs a new notebook.
