AMD raises the bar for notebook graphics with ATI Mobility Radeon HD 4000 series

[4T7]

Nvidia’s recently announced GeForce GTX 295 may have snatched the lead from the Radeon HD 4870 X2 as the world’s fastest single-card desktop graphics solution, but AMD is now ready to take the fight to the all-important notebook segment with a series of mobile graphics chips designed for everything from low-cost laptops to high-end gaming notebooks.

The new ATI Mobility Radeon HD 4000 series is derived from the RV770 architecture and resembles its desktop siblings, featuring up to 800 stream processors, support for GDDR5 and GDDR3 memory types, a 256-bit memory interface, and CrossFire support with the option to switch back and forth between discrete and integrated GPUs without rebooting.

Breaking down into the series we have the top end ATI Mobility Radeon HD 4850 and 4870, followed by the mid range HD 4670 and 4650 for mainstream systems, which has the same 320 stream units as the previous top-end units in the HD 3000 series but consumes less power. Lastly, the ATI Mobility Radeon HD 4500 and 4300 series will make their way into mainstream and ultraportable laptops with just 80 stream units to conserve energy and lower the price. All of the new parts will have support for Direct X 10.1 and support streaming 7.1-channel HD Audio through HDMI connections as well as HD playback all the way up to 1080p.

Systems from Asus, MSI and others will reportedly be available before the end of March. In fact, Asus announced new N81Vp and N51Tp laptops with Mobility Radeon HD 4600 GPUs a couple of days early, on Wednesday.

I am looking out for HD4650 to hit notebooks. I had said all along that it IS for notebooks, because it is definitely the most VFP (value for power) GPU and such things come to play only on notebooks. In desktop it and HD4670 get pwned by 9600GT.

But AMD better do something fast to combat the 9100GS, 9200GS and 9300GS GPUs from nVidia which are making a BIG mark on weakest of laptops.
