AMD is planning to unveil its Radeon HD 7950 graphics card by the end of January, while NVIDIA is anticipated to introduce its 28nm Kepler GPU in April, at the latest.

The sources noted that Nvidia wishes to make sure that the power consumption and the manufacturing process of the graphics chip all reach perfection before entering the 28nm generation. Since Nvidia is set to release its 28nm graphics card around the same time as Intel's upcoming 22nm Ivy Bridge processor, the sources believe Kepler series GPUs may have a chance to catch up with the demand for Intel's new CPUs.

Nvidia is set to release several 28nm Kepler-based GPUs including GK104, which will replace the existing GeForce GTX 560Ti; GK107, targeting the entry-level PC market; GK106, targeting the mid-range to entry-level market; GK110, which is equipped with two GK104 GPUs; and the highest-end GK112, which may be released in the fourth quarter or 2013.
