AMD A10-4657M vs AMD A8-4555M

AMD A10-4657M

► remove AMD A10-4657M

The AMD A10-4657M is a mobile quad-core processor based on the Trinity architecture. The processing unit is manufactured in 32nm SOI and integrates a 2.3 GHz CPU (up to 3.2 GHz w/ Turbo Core) with a relatively fast Radeon HD 7660G GPU alongside a dual-channel memory controller, video encoders and a northbridge. The A10-4657M is the BGA version of the A10-4600M.

The CPU cores are based on a reworked Bulldozer architecture called Piledriver. Although marketed as a quad-core processor, the A10-4657M 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 performs well in speeding up single-threaded performance, although it is still underperforms compared to 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 A10-4657M can perform anywhere from 0 to 25% faster than the Llano-based A8-3520M. Single-threaded workloads can especially benefit from the new architecture and the updated Turbo Core functionality. If compared to Intel, a Sandy Bridge Core i3-2310M is roughly similar to the A10-4657M, but results can still differ greatly from benchmark to benchmark. Nonetheless, CPU performance from the AMD processor should be sufficient for all daily workloads like Office, Internet browsing and even light video editing or gaming.

The integrated DirectX 11-compatible Radeon HD 7660G offers all 384 shader cores of the Trinity chip and, thanks to Turbo Core, will operate anywhere between 497 to 686 MHz depending on the current application demand. On average, the performance of the HD 7660G GPU is comparable to a dedicated Radeon HD 6650M and is noticeably faster than the HD Graphics 4000 as found on Intel’s Ivy Bridge platform.

The power consumption of the A10-4657M APU is rated at 35 Watt TDP and is therefore comparable to mid-range dual-core Ivy Bridge processors. Consequently, the A10-4657M is best suited for 14-inch notebooks or larger.

AMD A8-4555M

► remove AMD A8-4555M

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.
