With all difficulties, caused by the scarcity of 40 nm RV740 video chip , graphic card producers do not lose the hope to release the alternative versions radeon HD 4770. MSI company, for example, released the video card R4770-MD512/D3.
Here we have the radeon HD 4770 original designs with 512 mb GDDR- 3 memory. As it is known, the standard version radeon HD 4770 is equipped with 512 mb GDDR- 5 memory, its high frequency allows to ensure a good capacity even with the use of 128- bit bus. GDDR3 Memory deprives the Radeon HD 4770 of such advantages over competitors.
Before us GDDR- 3 microcircuit from Samsung production with 1 Gbit density, which has the access time not less than 1.0 ns.
In this series are encountered memory microcircuits with the access time from 1.5 ns to 1.0 ns; therefore, the range of possible memory frequencies is equal to 1333-2000 MHz DDR. Related Products :
