AMD A8-4555M vs Intel Core 2 Duo P7550
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 P7550
► remove from comparisonThe Intel Core 2 Duo P7550 is a dual core processor for laptops. It features 2.26 GHz and a shared level 2 cache of 3 MB. It is an OEM CPU and similar to the Core 2 Duo P8400 (additional Trusted Execution Technology, and VT-x) and Core 2 Duo P7570.
The performance of the P7550 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 P7550 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).
