Besides reference versions HD4890 we have an interesting nonstandard version radeon HD 4890. This product is prepared by ASUS company.
This card will appear in the MATRIX or TOP series. In the list of changes relative to the standard , we have a new power-supply system and increased operating frequencies (memory and core).
The power-supply system has a diagram of 6+2 phases with digital pulse-width modulator (PWM) and 8 pin power connector (instead of 6 pin ), it is controlled by VRM- chip. The vGPU can be controlled , for example, to 1,4 v. This must increase operational stability and improve the overclocking possibilities.
The frequencies assigned for this accelerator are: 900 MHz for GPU (instead of 850 MHz) and 1000 (instead of 975) MHz for the GDDR5 memory . Related Products :
