AMD had a number of problems when trying to adapt the manufacturing technology of its graphics card 40 nanometer lithography to 28.
This sounds that you like Chinese, means that the manufacturer is able to create 2 times more transistors in the same area as the previous generation. Graphics cards if you integrate more logic can increase performance and reduce consumption.
In a commercial strategy, since it was assumed that all 7000 series would use the new technology of 28 nanometers and architecture Graphic Core Next decides to draw the 7400M, 7500m series and you speak in this article the 7600M series laptops but with 40 nanometer and using the above architecture.
But do not take these misleading you have little to do with their older sisters.
Architecture. Terascale 2. It is based on which you can find on the Radeon 5000 for desktop PCs.
Manufacturing technology. They use 40 nanometers.
Graphics standards. It supports DirectX 11.
HD3D. It allows playback of content in three-dimensional format, both movies and games. Using an HDMI cable you can spend this kind of content to your TV.
UVD. Allow playback speed most used video formats like H.264 (MKV), MVC (Blu-ray 3D), MPEG-4 Part 2 (DivX / Xvid).
Onboard audio controller. Which can accelerate, how could it be otherwise, reproduction of the most common audio formats.
Working with multiple monitors simultaneously. If the laptop manufacturer allows this card is able to connect to 5 monitors simultaneously.
7610M. We have 400 Stream Processors working at 450MHz. You can have problems with many games and should therefore lower resolution and detail. Only supports DDR3 memory.
7630M. We have 480 Stream Processors 450MHz working Do not expect wild improvements over the previous one. Only supports DDR3 memory.
7650M. We have 480 Stream Processor that can operate between 450 and 550 MHz and can be used for almost every game but some will have to be reduced details. Only supports DDR3 memory.
7670M. We have again the same core working at 600 MHz will have the same limitations as the previous one. You can use DDR3 and GDDR 5 memory.
7690M. Same cores working between 600 and 725 MHz Actually there are several versions of this card. You have problems with certain games. You can use DDR3 and GDDR5.
7690M XT. Same nuclei to 725MHz. You will have the same limitations as the previous one. Only supports GDDR5 memory.
