Intel Core 2 Duo P8800 vs Intel Core i5-2435M vs Intel Core i5-2415M
Intel Core 2 Duo P8800
► remove from comparison
The Intel Core 2 Duo P8800 is a dual core processor for laptops. It features 2.66 GHz and a shared level 2 cache of 3 MB. Due to the smaller cache (Core 2 Duo T-Models got usually 6 MB at this clock rate), the TDP is only 25 Watt (instead of the 35 Watt of the T-models).
Due to the relatively high clock speed, modern games (in 2009) should not be limited by the CPU speed (in conjunction with a middle class graphics card). High end gamers should choose a higher clocked Dual Core instead (when using a high end GPU).
The P8800 uses a Penryn (Montevina Update) core that features 2 integer units, 1 floating point unit, 1 load unit, and 1 store unit in a 14-stages long pipeline. Due to the Wide Dynamic Execution Technology, the core is able to simultaneously execute up to four instructions.
The integrated Enhanced Speedstep is able to downclock the core dynamically as low as 1200 MHz to save power (in idle mode).
The Core 2 Duo P8800 can be used in a Socket P socket with 479 pins: Socket P / Micro Flip-Chip Pin Grid Array (Micro-FCPGA) requires 479-pin surface mount Zero Insertion Force (ZIF) socket (mPGA479M socket) or Micro Flip-Chip Ball Grid Array (Micro-FCBGA) for surface mount (479-ball)
Intel Core i5-2435M
► remove from comparison
The Intel Core i5-2435M is a fast dual core processor at the time of introduction in Q3 2011. It is based on the Sandy Bridge architecture and offers Hyperthreading to handle 4 threads at once (for a better usage of the pipeline). Compared to the faster Core i7, the i5 offers a smaller last level cache of 3MB. The base clock speed is 2.4 GHz but due to Turbo Boost it can reach 2.7 GHz (2 cores active) and 3 GHz (1 core active). Compared to the 2510M, the 2435M does not support AES, VT-d, and Trusted Execution functions.
Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most noteable improvements is the improved Turbo 2.0 and the integration of the graphics card into the 32nm CPU core.
The i5-2435M offers an integrated graphics card (Intel HD Graphics 3000) which is clearly faster then the older Intel HD Graphics in the Arrandale CPUs. As the new GPU is included in the CPU, it is also manufactured in 32nm and shares the fast level 3 cache with the CPU cores (using a new ring bus). In the 2435M it is clocked from 650-1300MHz (with Turbo Boost). In comparison the quite similar i5-2430M offers only 1200MHz.
Furthermore, an improved dual-channel DDR3 memory controller is included on the CPU die that is used by the CPU and GPU part.
Due to the improved architecture and the new Turbo Boost 2.0, the average performance of the Core i5-2435M is higher than a similar clocked Arrandale Core i5. In our benchmarks, the 2435M was able to beat the fast Intel Core i5-560M with 2.7-3.2GHz and is therefore suited for even demanding tasks.
The 35W TDP rating includes the integrated GPU and memory controller.
Intel Core i5-2415M
► remove from comparison
The Intel Core i5-2415M is a fast dual core processor at the time of introduction in Q1 2011. It is based on the Sandy Bridge architecture and offers Hyperthreading to handle 4 threads at once (for a better usage of the pipeline). Compared to the similar Core i5-2410M, the 2415M is manufactured with a smaller package and only for the BGA1023 socket. In difference to the faster Core i7, the i5 offers a smaller last level cache of 3MB. The base clock speed is 2.3 GHz but due to Turbo Boost it can reach 2.6 GHz (2 cores active) and 2.9 GHz (1 core active). Compared to the 2510M, the 2415M does not support AES, VT-d, and Trusted Execution functions.

In the 2415M it is clocked from 650-1200MHz (with Turbo Boost). The faster Sandy Bridge CPUs are clocked up to 1300 MHz (like the i5-2520M).
Furthermore, an improved dual-channel DDR3 memory controller is included on the CPU die that is used by the CPU and GPU part.
Due to the improved architecture and the new Turbo Boost 2.0, the average performance of the Core i5-2415M is higher than a similar clocked Arrandale Core i5. In our benchmarks, the 2415M was able to beat the fast Intel Core i5-560M with 2.7-3.2GHz and is therefore suited for even demanding tasks.
