AMD A8-5550M vs AMD A4-5145M vs AMD A10-5745M
AMD A8-5550M
► remove from comparison
The AMD A8-5550M is a mobile quad-core processor based on the Richland-architecture. As successor to the A8-4500M, the A8-5550M 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 A8-5550M performs about 15 percent slower than the A10-5750M and similar to 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. With fast dual-channel memory, performance matches 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 A4-5145M
► remove from comparison
The AMD A4-5145M is a mobile ultra-low-voltage dual-core processor based on the Richland architecture. The APU integrates one module with 2.0 to 2.6 GHz, a Radeon HD 8310G 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 module 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 A4-5145M should be similar to the A6-4455M and the Pentium 977. For everyday tasks such as Internet or Office the performance is adequate, but not for very complex software or modern games.
The graphics unit called Radeon HD 8310G offers 128 shader units (VLIW4) and is slightly faster than the HD Graphics (Ivy Bridge). The core is clocked at 424-554 MHz (turbo).
The power consumption of the entire APU is rated at 17 watts, which is similar to other ULV CPUs. Therefore, the APU is suitable for 12-inch ultraportables or bigger.
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.
