AMD A8 Pro-7150B vs AMD A10-7400P vs AMD A6-7000

AMD A8 Pro-7150B

The AMD A8 Pro-7150B is a power efficient ULV (Ultra Low Voltage) quad-core processor based on the Kaveri architecture. It was revealed in June 2014 for notebooks and is manufactured by GlobalFoundries using a 28 nm SHP process. In addition to having two CPU modules for a total of four integer cores clocked at 1.9 - 3.2 GHz, the AMD chip also integrates a Radeon R5 GPU clocked at up to 533 MHz with 384 GCN shaders and a dual-channel DDR3-1600 memory controller.

Technically, the 7150B is almost identical with the consumer model A10-7300. However, AMD guarantees an especially high stability and durability for the business-oriented Pro-Series.

Architecture 

Kaveri is the successor to the 2013 Richland architecture (e.g. A10-5750M). The revised CPU cores, codenamed Steamroller, represent the third generation of the module-based Bulldozer design. A number of major changes include modified decoders (now one per integer core), optimized branch prediction, and increased L1 I-cache from 64 KB to 96 KB per module. These revisions boost the performance per clock slightly over a similarly clocked Richland APU. For more details about the AMD Kaveri architecture, see our detailed analysis here:

Analysis of the AMD Kaveri Notebook Platform

Performance 

According to the clock rates, the A8 Pro-7150B should offer a CPU performance level similar to the Haswell-based Intel Core i3-4010U. Overall, the 7150B will be sufficient for all daily workloads (Office, Internet browsing, multimedia) as well as light multitasking. Detailed benchmark can be found on the cpu page of the A10-7300 APU.

Graphics

The Radeon R5 (Kaveri) GPU of the A8 Pro-7150B features a core clock of up to 533 MHz and 384 shader units. Since the GPU is based on AMD's GCN 1.1 architecture, both DirectX 11.2 "Tier 2" and Mantle are supported. Furthermore, the GPU can be used for general purpose computing in various applications, such as Adobe Photoshop via the OpenCL API. 

In terms of 3D performance, the GPU should be roughly as fast as a dedicated GeForce GT 720M and can handle many current games at low or medium settings at (W)XGA resolution.

Power Consumption

The power consumption of the entire APU is rated at 19 Watts, which is somewhat above the Haswell ULV CPUs from Intel (15 W including chipset). Nevertheless, the A8 Pro-7150B is suited for 12 - 13-inch notebooks or larger.

AMD A10-7400P

The quad-core AMD A10-7400P is a mid-range processor based on the Kaveri architecture. It was revealed in June 2014 for notebooks and is manufactured by GlobalFoundries using a 28 nm SHP process. In addition to having two CPU modules for a total of four integer cores clocked at 2.5 - 3.4 GHz, the AMD chip also integrates a Radeon R6 GPU clocked at up to 654 MHz with 384 GCN shaders and a dual-channel DDR3-1866 memory controller.

Performance 

According to the clock rates, the A10-7400P should offer a CPU performance level similar to the Sandy Bridge-based Intel Core i3-2330M or 2350M. Overall, the A10-7400P will be sufficient for multitasking daily workloads (Office, Internet browsing, multimedia) as well as more demanding programs.

Graphics

The Radeon R6 (Kaveri) GPU of the A10-7400P features a core clock of up to 654 MHz and 384 shader units. Since the GPU is based on AMD's GCN 1.1 architecture, both DirectX 11.2 "Tier 2" and Mantle are supported. Furthermore, the GPU can be used for general purpose computing in various applications, such as Adobe Photoshop via the OpenCL API. 

In terms of 3D performance, the GPU benefits from its high raw computational power and memory support up to DDR3-1866. Thus, the Radeon R6 is just slightly behind a dedicated GeForce GT 730M and can handle many current games at low or medium settings at WXGA resolution.

Power Consumption

The power consumption of the entire APU is rated at 35 Watts, which is similar to other competing mid-range models. As a result, the A10-7400P is best suited for 14-inch notebooks or larger.

AMD A6-7000

The AMD A6-7000 is a mobile dual-core processor based on the Kaveri architecture. In addition to one CPU module (2 integer cores) clocked at 2.2 - 3.0 GHz, the chip also integrates a Radeon R4 graphics unit (192 GCN shaders, 533 MHz). According to its TDP of 17 watts, the APU is suitable even for very small and thin laptops (11 - 12 inches or bigger).
