ATI, graphics products group of Advanced Micro Devices, on Tuesday officially released the world’s first graphics processors made using 40nm process technology. The new chips enable very high graphics performance at lower costs as well as with relatively low power consumption.
ATI Mobility Radeon HD 4830 and HD 4860 graphics solutions are based on the code-named M97/RV740 chip that features 640 stream processors, 32 texture units, 16 render back ends and 128-bit GDDR3/GDDR4/GDDR5 memory controller. The new graphics chips can operate at relatively high speeds without breaking thermal budget and deliver rather high performance. Functionality of the novelties is very similar compared to their desktop brethren, e.g., they support DirectX 10.1 and OpenGL 3.0 feature-sets, hardware-accelerated high-definition video playback and so on.
“People now decidedly prefer mobile PCs, and innovations like this 40nm mobile GPU show AMD is uniquely positioned to make the best entertainment experiences of desktop PCs possible in a notebook. Laptops that feature these tiny, powerful but efficient graphics engines can run today’s most demanding game titles at beyond 1080p HD resolution, or playback full 1080p HD video with high energy efficiency thanks to ATI PowerPlay and 40nm process technology,” said Rick Bergman, senior vice president and general manager of graphics products group of AMD.
“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,” Mr. Bergman claimed.
The new 40nm production process allows notebook manufacturers to deliver more graphics horsepower in a smaller ASIC die size, giving the end-user access to highly capable discrete graphics inside smaller notebooks. According to benchmarks carried out by AMD's graphics product group, ATI Mobility Radeon HD 4860 beats the Mobility Radeon HD 4850 noticeably by scoring 9302 in 3DMark06 compared to 8647 marks of the predecessor.
“AMD continues to push the envelope of graphics processor performance, energy efficiency, and leading features with the introduction of its 40nm graphics processors. TSMC and AMD have a long history of success bringing the first graphics processors to market on new process technologies, including 90nm, 80nm, 65nm, 55nm and now 40nm,” said Mark Liu, senior vice president of advanced technology business at TSMC.
ATI Mobility Radeon HD 4860 graphics solution will be featured in the forthcoming Asus K notebook.
“Asus always strives to be first to deliver the newest and most advanced technology to our customers and launching the Asus K series notebook with these new graphics processors from AMD demonstrates that,” said Henry Yeh, general manager of Asus’ notebook business unit.
