Advanced Micro Devices (AMD) has announced the new mobile graphics chips i.e. Radeon 7700, 7800, 7900.
[hana-code-insert name=’StumbleUpon’ /][hana-code-insert name=’Reddit’ /]AMD’s Radeon Chips are found in many of the laptop series including HP’s Envy line and Apple’s MacBook Pro. The chips use “Graphics Core Next” (GCN) architecture introduced in the 7000 series chips. AMD has offered many new features in these chips such as easy switching between integrated and discrete graphics.
These chips are made for not only gaming laptops but also for thin media rich laptops due to the AMD Enduro technology, AMD Powergate, and AMD ZeroCore technology.
These GPUs are among the better power-efficienct chips. According to the company, the chips dynamically shutdown parts when not in use resulting in less power consumption. The chips are 28nm parts as compared to the original HD7000 GPUs, which were of 40nm in size. HD7700, HD7800 and 7900M are codenamed as “Chelsea”, “Heathrow” and “Wimbledon” respectively.
The company said the HD7900 is among “the most technologically advanced and feature-rich mobile GPUs AMD has ever created.” This chip has 1280 components running at 850 Mhz with 2GB of on-board GDDR5 RAM. It can compute 2176 gigaflops. The 7800M graphics chip has 640 stream processors, runs at 800 megahertz, and can compute at 864 gigaflops. And the low-end 7700M graphics chip has 512 stream processors, runs at 675 megahertz, and can compute 589 gigaflops.
“We’re bringing a lot of innovation to notebook computers,” said Ogi Brkic, an AMD product manager.
