Thread: ATI Mobility radeon hd 4000 series driver

One of the paths AMD is capable to try and characterize ATI Mobility Radeon graphics processing units, less having to plan and construct numerous mobile address cards that set in multiple notebook form elements, is to genegrate completetly-loaded, custom reference cards that will set into standard PCI Express x16 ports.

The cards would not be utilized in any real retail product, but they permit AMD to try complete of the several characteristics and practicality, and experiment with clock velocities and voltages to well tune and stable function, thermal output, and power consumption.What you look imaged here is only such a card.

The particular depicted under is an ATI Mobility Radeon HD 4670, PCI Express-based reference card. We spoke about the fresh mobility Radeon HD 4000 serials throughout CES before recent year; more details are present at this connection.

The reference card pictured here is skilled with each kind of output supported through the graphics processing unit--Displayport, DVI, VGA, S-Video / HD element, and HDMI--and it still



has CrossFire links for experimenting with multi-GPU forms. Wehave had a pair of Mobility Radeon HD 4670 and 4500 class reference cards in house for a moment just, and have a sneak glance at approximate function utilizing a desktop platform for trying on the pages ahead.

The Mobility Radeon HD 4670 and 4500 serials cards we got for rating looked closely identical, store for the the memory chips utilized on every card, hence the individual set of images throughout. The Mobility Radeon HD 4670 we tried characteristics 320 stream processors, with a core graphics processing unit clock frequency of 675MHz, and 512MB of GDDR3 memory functioning at an still 800MHz.

It is a comparatively high function extending that will be placed in upper--mainstream market sections. The Mobility Radeon HD 4500 serials extending sports just 80 stream processors, but with a 680MHz core graphics processing unit clock, and 256MB of GDDRIII frame buffer memory too functioning at 800MHz, but linked through a 64-bit interface--the 4670 has a 128-bit memory interface. The Mobility Radeon HD 4500 serials will be placed in thin and light market section.
