AMD has added the entry level Radeon R5 230 to it's retail graphics card line-up. Previously only available for the OEM market, the R5 230 is a rebrand of the Radeon HD 6450 and HD 7450, albeit with the memory clocked to match the 7450, which is slower than the 6450. The card uses a Caicos Pro GPU, first launched in February 2011, and powered by the TeraScale 2 Unified Processing Architecture, introduced a year earlier.
The R5 230 has 160 shaders, 8 TMUs and 4 ROPs. The core is clocked at 625 MHz, the same as its predecessors. It offers a throughput of 5.0 gigatexels/s and 2.5 gigapixels/s, as well as compute power of 200 GFLOPS. AMD describe the R5 series cards as "not just great for gaming", although it is unlikely that it will have the power to play modern games with decent settings.
It has 1 GB DDR3 memory, with a 64-bit interface. The memory is clocked at an effective 1066 MHz, giving it a bandwidth of 8.53 GHz. It supports all the standard APIs, including DirectX 11.0, OpenGL 4.3 and OpenCL 1.2. It is a single-slot card, and is 6.6 inches long. It had a DVI-D output, an HDMI and a VGA connector. The TDP is 19 Watts.
The card does not provide any hardware video decoders, unlike the original HD 6450. It supports 2-way crossfire, without a crossfire interconnect bridge. It can be connected to up to 3 displays. Also, it uses AMD PowerPlay technology for power saving, but does not support ZeroCore or PowerTune technologies.
We have not yet seen confirmed prices, although we believe reference cards will be priced around the $50 mark.
