If PowerColor company already released the radeon HD 4870 with 1GB memory, then remaining AMD partners are not active in this sphere.

Last week MSI company presented the video card R4870-T2D1G, which is characterized by standard cooler and 1GB GDDR5 memory .Frequencies remained standard - 750 MHz for the core and 3600 MHz DDR for the memory.
Since the additional memory capacity manifests its advantages only in heavy graphic regimes, to the owners of monitors with diagonal less than 24 inches there is no large sense to buy the radeon HD 4870 version with 1GB memory .
