AMD A10-5745M
► remove from comparison
The AMD A10-5745M is a mobile low-voltage quad-core processor based on the Richland architecture. The APU integrates two modules with 2.1 to 2.9 GHz, a Radeon HD 8610G graphics card and a DDR3(L)-1333 memory controller.
Compared to Trinity, Richland has been modified just slightly. Therefore, no changes in the feature set or the Pro-MHz performance can be reported. The design of the chip is still based on the Bulldozer architecture, which consists of so-called modules. Each of the two modules integrates 2 integer units, but only one FPU. Just like Trinity, Richland supports nearly all current techniques such as AVX (including FMA), AES or Turbo Core.
The CPU performance of the A10-5745M should be similar to a Core i3-2310M. Thus, the APU is sufficiently for most modern applications and many games.
The graphics unit called Radeon HD 8610G offers all 384 shader units (VLIW4) and is slightly faster than the HD 7660G. The core is clocked at 533-626 MHz (turbo).
The power consumption of the entire APU is rated at 25 watts, which is slightly below common middle-class CPUs. Therefore, the APU is suitable for slim 13-inch notebooks or bigger.
AMD A8-5557M
► remove from comparison
The AMD A8-5557M is a mobile quad-core processor based on the Richland-architecture. In contrast to the A8-5550M, the 5557M is a BGA version. As successor to the A8-4500M, the A8-5550M/5557M has a slightly higher CPU and graphics performance and settles in the lower middle class. The APU integrates 4 CPU cores, a DirectX 11 graphics unit and the Northbridge along with a DDR3 memory controller.
Compared to Trinity, Richland has been modified just slightly. Therefore, no changes in the feature set or the Pro-MHz performance can be reported. The design of the chip is still based on the Bulldozer architecture, which consists of so-called modules. Each of the two modules integrates 2 integer units, but only one FPU. Just like Trinity, Richland supports nearly all current techniques such as AVX (including FMA), AES or Turbo Core.
According to the clock rates of 2.1 to 3.1 GHz, the A8-5557M should perform about 15 percent slower than the A10-5750M and just reach a Core i3-2310M. Consequently, the performance in current applications and games is sufficient.
The graphics unit called Radeon HD 8550G offers 256 shader units (VLIW4) and clocks slightly higher than the HD 7640G at 554 - 720 MHz. With fast dual-channel memory, performance is expected to match a dedicated Radeon HD 7570M.
The power consumption of the entire APU is rated at 35 watts, which is comparable to conventional middle-class models of competition. Thus, the APU is best suited for 14 inch notebooks or bigger.
AMD A8-5545M
► remove from comparison
The AMD A8-5545M is a mobile low-voltage quad-core processor based on the Richland architecture. The APU integrates two modules with 1.7 to 2.7 GHz, a Radeon HD 8510G graphics card and a DDR3(L)-1333 memory controller.
Compared to Trinity, Richland has been modified just slightly. Therefore, changes at the feature set or the performance per clock are not expected. The design of the chip is still based on the Bulldozer architecture, which consists of so-called modules. Each of the two modules integrates 2 integer units, but only one FPU. Just like Trinity, Richland supports nearly all current techniques such as AVX (including FMA), AES or Turbo Core.
The CPU performance of the A8-5545M is expected to be roughly on par with a Pentium P6100. For most current applications and less demanding games, the APU has sufficient power.
The graphics unit called Radeon HD 8510G offers all 384 shader units (VLIW4) and is slightly faster than the HD 7640G. The core is clocked at 450-554 MHz (with turbo).
The power consumption of the entire APU is rated at 19 watts, which is slightly above normal ULV CPUs. Thus, the APU is best suited for 13 inch notebooks or bigger.
