AMD Goes Mobile with 40nm Process, Announces ATI Mobility Radeon HD 4860 and HD 4830


ATI today announced a pair of mobility chips -- ATI Mobility Radeon HD 4860 and HD 4830 -- built off of AMD's new 40nm manufacturing process, purportedly making them the first-ever 40nm notebook GPUs.

Both the HD 4860 and HD 4830 come with 640 stream processor, 826 million transistors, support for DirectX 10.1, dual integrated DisplayPort, HDMI with 7.1 surround sound, and are CrossFireX ready. The 128-bit HD 4860 boasts a 650MHz core clockspeed and GDDR5 memory clocked at up to 4Gbps. The HD 4830 (also 128-bit), meanwhile, ships with a core clockspeed ranging from 450MHz to 600MHz, and GDDR3 clocked between 800MHz to 900MHz.

"It's not just 40nm process technology that makes these chips so potent, they are based on the same award-winning TeraScale engine of our ATI Radeon™ HD 4800 desktop series," Rick Bergmen, senior VP and GM for AMD's graphics products group, wrote in a blog post . "Combining this gaming power with our ATI Avivo™ HD technology and Unified Video Decoder will keep all your HD content humming along at full 1080p resolution with bright colors and seamless playback on your HD display. We've also packed in our power-saving technologies like ATI PowerPlayTM, ATI PowerXpressTM, and ATI Switchable Graphics™ technologies so that you can keep gaming, watching and surfing a little longer."

Bergmen went on to say that 40nm desktop parts are "coming soon," with at least one site having already posted benchmarks of what's believed will be ATI's first 40nm-based desktop graphics release.

As for the 40nm Mobility parts, Asus is scheduled to ship laptops using the new processors in the second half of 2009.
