AMD company will soon enlarge the evergreen products with two graphic accelerator models with the support Of directX 11 radeon HD 5750 and HD 5770. It is expected that video card will appear on sale at the end of October, and they will fill their niche in the price range up to $200.
Here is the photograph of graphic accelerator radeon HD 5750.
Here is the graphic processor juniper. The base layer of RV870 chip, made on 40 nm technical process , appears greater according to the sizes, than its predecessor RV740. Around it are located four chips GDDR5 memory .
In comparison with radeon HD 5800, the card has a short printed-circuit board . In the reference design card the GDDR5 memory chips used are from hynix production .
This card is equipped with the four-phase power diagram. They are two DVI- D, one HDMI and one DisplayPort.
This Graphic accelerator is characterized by the presence of 1120 stream processors, 128- bit memory and the support the regime crossFireX. The card specifications are not official, but the driver shows that GPU and memory operate at the frequency 700 and 4200 MHz respectively.
Here is the comparison of radeon HD 5750, HD 4770, HD 4850 and GeForce GTS 250. In the tests 3DMark vantage and 3DMark 06 the card showed the best result , better than radeon accelerators previous generations, and equal to the GeForce GTS 250. In the test was used the processor core 2 Duo e8400 with the clock frequency 3 GHz.
In the test 3DMark 06 the result composed 12931 .
In 3DMark vantage the result on the GPU part composed 6681 .
After 220 seconds in the test furMark, the GPU temperature was 70 degrees, and the average quantity of frames per second was equal to 35. At rest the video card temperature did not exceed 53 degrees.
Probably, after the official announcement of graphic accelerator series radeon HD 5700 we will see the new data about their productivity, and also the non reference video card versions . Related Products :
