ATI Mobility Radeon HD 4830 / HD 4860 Graphics
It is therefore logical in the mobile chip low that ATI Has officially launches its first GPU engraved in 40 nm. We speak here of the RV740 GPU, the first graphics chip in 40 nm ATI, engraved by TSMC. It offers some 640 processing units and a bus 128-bit memory on GDDR5 RAM. Two mobile GPU models are proposed: Mobility Radeon HD 4860 and sister 4830. The 4860 will arrive soon in laptops from Asus K, from the second quarter. The 4830 version will remain equipped with GDDR3 RAM, while the 4860 will have twice the bandwidth through the GDDR5. The RV740 at the base of these two chips is equipped with 826 million transistors to provide some 832 Gflops of power to the Mobility Radeon 4860. The TDP of the chip is not specified, but the technologies and PowerXpress Switchable Graphics are present to save energy. It will also have the right players for CrossFireX nomades hard-hearted.

Quote:
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.

Re: ATI Mobility Radeon HD 4830 / HD 4860 Graphics
Hello , It's a pity it is impossible to change the graphics card on laptop, it is the only limiting factor on my own. I have a faulty 8600M GT, I had to update my bios to limit overheating, so I have now run games like TF2 at minimum almost not cut it then that prior to day of the bios, it worked without problems in medium-high. I put one of these well ATI to replace, but they should sell it only to assembler
