RV710: first info on Radeon HD 4550 AMD

[Humberto]

Expreview revealed this week that could provide the technical characteristics of future Radeon HD 4550 AMD, graphics card entry range, whose prices should be between 40 and 60 dollars, depending on the amount of video memory onboard . While the Radeon HD 4650 and 4670 have just been launched, AMD introduces 4550 with a downward revision, within which the number of units processing shaders would be reduced from 320 to 80, a 64-bit memory interface. It speaks also of a chip composed of 240 million transistors, with a GPU clocked at 600 MHz memory and a video showing a standard frequency of 800 MHz.



The main attraction of RV710 lie in its ability to be content with a passive cooling device, which could be a weapon of choice in the field of PC lounge, where silence components is a major problem. Positionnées in front of nVidia GeForce 9400GT, Radeon HD 4550 would be divided into two versions: the first will have 256 megabytes of video memory and adopt a format type low profile. The second embarquerait 512 MB of memory, and would present itself as a full card format, enriched with a possible DisplayPort or HDMI connections.

AMD is designing a new graphics chipset that will not only occupy one of its least expensive price rungs but require very little heat and noise, a leaked presentation obtained by Expreview shows. The Radeon HD 4550 would sit below the new 4600 series in performance by cutting the number of visual shader processors down from 320 to 80 on a 64-bit memory bus but would also drop in size and consequently in power; at less than half as many transistors in the chip, a 4550 would consume under 25 watts of power versus 50 for the 4650.

Every version would run at a 600MHz main core speed and with 800MHz actual (1.6GHz effective) video memory and at least one DVI jack. The 512MB card would afford extra room for DisplayPort and HDMI outputs, while the 256MB edition would fit smaller, analog S-video and VGA connectors.

The change would also let card makers produce either a smaller or quieter board depending on the model. A card with 256MB of memory will require a small fan but take up just over half the width of a normal card; a 512MB version will occupy normal width but rely entirely on a heatsink to passively cool the chipset and render the card entirely silent.
