Intel Core 2 Duo P7370 vs AMD A8-4555M vs Intel Core 2 Duo P8800
Intel Core 2 Duo P7370
► remove from comparisonThe Intel Core 2 Duo P7370 is a dual core processor for laptops. It features 2.0 GHz and a shared level 2 cache of 3 MB. It is based on the 45nm Penryn core, but most likely Trusted Execution and Virtualization (VT-x) are disabled.
The P7370 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).
AMD A8-4555M
► remove from comparison
The AMD A8-4555M is a mobile ultra-low-voltage (ULV) quad-core processor based on the Trinity architecture. Officially introduced in Q4 2012, it is the direct successor to the Llano A-series of APUs (Accelerated Processing Unit). The processing unit is manufactured in 32nm SOI and integrates a 1.6 GHz CPU (up to 2.4 GHz w/ Turbo Core) with a relatively fast Radeon HD 7600G GPU alongside a dual-channel memory controller, video de- and encoders and a northbridge.
The CPU cores are based on a reworked Bulldozer architecture, called Piledriver. Although marketed as a quad-core processor, the A8-4555M includes only two modules with four integer-cores and two floating-point cores total. As a result, the CPU is not a true quad-core processor.
When compared to previous Bulldozer cores, AMD has managed to improve upon the IPC (instructions per clock) performance of Trinity cores while allowing for higher clock frequencies. However, when compared to its Llano predecessor, the multithreaded performance of Trinity has only been slightly improved. The enhanced Turbo Core 3.0 feature functions well in speeding up single threaded performance, although it is still not on the same level as Intel’s Turbo Boost equivalent. Regardless, AMD has managed to include other features as well, such as the AVX extension (including FMA) and support for AES encryption.
In terms of raw general performance, the A8-4555M performs somewhere between the ULV Pentium and Core i3 series from Intel. Because of the lower frequency, the A8-4555M is 15 - 20 % slower than the A10-4655M (25 W TDP). Nonetheless, CPU performance of the AMD processor is sufficient for all daily workloads like Office, Internet browsing and even light video editing or gaming.
The APU integrates a DirectX 11-compatible GPU called Radeon HD 7600G.
The power consumption of the A8-4555M APU is rated at 19 Watt TDP and therefore comparable to Intels ULV-processors. Consequently, the A8-4555M is best suited for thin-and-light notebooks.
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)
