ATI introduces 40nm Mobility Radeon HD 4830 and 4860

Posted on Tuesday, March 03 2009 @ 17:50:15 CET by

The first 40nm GPUs from AMD are mobile parts, they were paperlaunched today and go under the names of Mobility Radeon HD 4860 and Mobility Radeon HD 4830. These GPUs may be the mobile version of the 40nm RV740, they have 640 stream processors down from the 800 found on the RV770. Both chips have 826 million transistors and feature a 128-bit memory bus, the Mobility Radeon HD 4830 uses GDDR3/DDR3 memory while the Mobility Radeon HD 4860 supports GDDR5.

According to the specifications, the Mobility Radeon HD 4830 will have a core clocked between 450-650MHz with memory clocked at 1600-1800MHz. The computing power of this card will be between 512 GFlops to 768 GFlops. The faster Mobility Radeon HD 4860 will have a 650MHz core, up to 4Gbps GDDR5 memory and a computing power of 832GFlops. AMD says the Mobility Radeon HD 4860 will be slightly faster than the 55nm Mobility Radeon HD 4850.

The first ASUS notebooks with the Mobility Radeon HD 4860 and 4830 should arrive in Q2 2009.

AMD (NYSE: AMD) today announced the world’s first graphics processors to harness 40nm process technology: the ATI Mobility RadeonTM HD 4860 and ATI Mobility RadeonTM HD 4830. These feature-rich graphics processors redefine mobile PC entertainment with advanced capabilities including support for the latest Microsoft DirectX® 10.1 games, a home theater-quality HD multimedia experience, and energy-efficient features for long battery life at work, at home or at play.

“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,” said Rick Bergman, senior vice president and general manager, Graphics Products Group, AMD. “Depending on the performance of the panel or external monitor, 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.”

ATI Mobility Radeon HD 4860 graphics 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, GM of ASUS’ Notebook Business Unit.

The new 40nm production process allows notebook manufacturers to deliver more graphics horsepower in a smaller ASIC die size, giving people access to highly capable discrete graphics ideal for smaller notebooks. This milestone marks the fifth consecutive first-to-market process transition for ATI graphics processors.

“AMD always seeks to deliver the most advanced, yet relevant technology to our customers,” continued Bergman. “We were first with DirectX® 10.1 support, first to design graphics cards supporting GDDR5 memory technology, first with WHQL certified drivers for Windows Vista®, first to launch a unified shader architecture, and for the fifth consecutive time, first to launch GPUs based on a new process node. That’s a meaningful track record of reliable execution for our customers.”

“AMD continues to push the envelope of graphics processor performance, energy efficiency, and leading features with the introduction of its 40nm graphics processors,” said Mark Liu, senior vice president, Advanced Technology Business, TSMC. “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.”

The GPU for the best mobile HD entertainment
ATI Mobility Radeon HD 4860 and ATI Mobility Radeon HD 4830 graphics processors feature powerful 3D engines derived from the award-winning ATI Radeon™ HD 4800 desktop series architecture with support for DirectX 10.1. Take crisp, detail-rich images and outstanding visual effects wherever you go for unparalleled levels of 3D gaming realism. The ATI Mobility Radeon HD 4860 supports GDDR5 memory technology contributing to stunning improvements in game play and performance with nearly twice the memory bandwidth of GDDR3.

Home theater enthusiasts can enjoy a portable HD experience with full 1080p HD viewing on HD-capable displays and or TVs. People can upscale to nearly twice the display resolution of HD content or watch standard definition video in near-HD quality with enhanced DVD up-scaling*. The second generation AMD Unified Video Decoder (UVD) keeps the CPU free to run social media applications or virus scan while UVD helps process intensive content such as Blu-ray movies. This helps lower power consumption and reduces the need for high fan settings, enabling a quieter and cooler laptop experience.

Leading energy efficiency
Additional power-saving features include ATI PowerPlay™, ATI PowerXpress™, and ATI™ Switchable Graphics™ technologies.
