Lenovo IdeaPad Z50-75 Notebook (A10-7300) Review Update
AMD A10-7300 | AMD Radeon R6 M255DX | 15.60" | 2.5 kg
The AMD A10-7300 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 R6 GPU clocked at up to 533 MHz with 384 GCN shaders and a dual-channel DDR3-1600 memory controller.
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 our benchmarks, the A10-7300 offers a CPU performance level similar to the Haswell-based Intel Core i3-4010U. Only the single thread performance is a bit lower, despite AMDs significantly higher (turbo) clock rate. Overall, the A10-7300 will be sufficient for all daily workloads (Office, Internet browsing, multimedia) as well as light multitasking.
Graphics
The Radeon R6 (Kaveri) GPU of the A10-7300 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 is roughly as fast as a dedicated GeForce GT 720M and can handle many current games (as of 2014) 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 A10-7300 is suited for 12 - 13-inch notebooks or larger.
