AMD Radeon R2 (Stoney Ridge)

AMD Radeon R2 (Stoney Ridge)

The AMD Radeon R2 (Stoney Ridge) is an integrated graphics adapter of the weakest mobile dual-core Stoney Ridge APUs. At its launch, it is being used in the AMD E2-9010 and probably has 128 shaders running at up to 600 MHz. The performance can vary heavily depending on the configured TDP and the system memory.

Architecture and Features

The Radeon R4 is equipped with two cores from the third GCN generation (often called GCN 1.2 or 2.0 by the press). This means it is very similar to the Tonga desktop chip and supports DirectX 12 (FL 12_0), but the graphics cores can also be accessed via Mantle, OpenGL, and OpenCL. The GPU supports the HSA 1.0 standard as well and can therefore use the connection with the CPU cores very efficiently. The technical specifications are identical to the Carrizo predecessor. 

The video unit includes the UVD 6 (Unified Video Decoder), which can decode HEVC/H.265 and 4K with support from the hardware. More details are available in our dedicated Stoney Ridge article. 

Power Consumption

Depending on the model and configured TDP (cTDP), the 28 nm chip is specified with 10 up to 15 Watts. This means it can also be used for thin and light notebooks.
