Intel Core 2 Duo P8400 vs AMD E1-1200
Intel Core 2 Duo P8400
► remove from comparison
The Intel Core 2 Duo P8400 is a dual core processor for laptops. It features 2.26 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).
The performance of the P8400 is on par with the fast Turion II Ultra with about 2.4 to 2.6 GHz. Modern demanding games like Supreme Commander may be limited by the CPU performance. High end gamers should choose a higher clocked Core 2 Duo (or Core i5 / i7).
The P8400 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 800 MHz to save power (in idle mode).
The Core 2 Duo P8400 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)
AMD E1-1200
► remove from comparisonThe AMD E1-1200 (codename Zacate, not to be confused with the Ryzen 3 1200 from 2017) is a dual-core processor for small notebooks and netbooks. It is produced on a 40 nm process and offers a relatively powerful integrated GPU and a single channel DDR3-1066 memory controller. Compared to the older E-300, which is based on the same chip, the E1-1200 offers a 100 MHz higher CPU clock rate.
The E1-1200 has two Bobcat cores running at 1.4 GHz (no Boost here) that can access 512 KB of L2 cache per core. In comparison to the Atom processors, the Bobcat architecture uses an "out-of-order" execution and is therefore faster at the same clock speed.
The integrated Radeon HD 7310 GPU offers 80 shaders and an UVD3 video decoder. Compared to the slow GMA 3150 in the Atom processors, an HD 7310 offers a lot more performance and is about as fast as the Nvidia ION graphics solution. The HD 7310's clock rate is 500 MHz to be very similar to the HD 6310 (488 - 500 MHz depending on the APU).
Performance
The average E1-1200 in our database is in the same league as the Celeron N2807 and the AMD E-300, as far as multi-thread benchmark scores are concerned. This is an outrageously slow chip, as of mid 2022.
Power consumption
This E-series APU has a default TDP of 18 W, meaning an active cooling solution is pretty much a must.
The AMD E1-1200 is built with a 40 nm process for very, very, very low, as of 2022, energy efficiency.
