AMD has not exactly been brilliant at keeping its next-generation mobile graphics chips secret. If this was a deliberate tactic or not, we can not answer, but after those PC manufacturers have already begun to leak information about the Mobility Radeon HD 5000 series is now even Intel itself has carried out official information about the four new series which will now be taking DirectX 11 technology to our laptops.

We have already seen ASUS show up laptops with ATI Mobility Radeon HD 5870, but apart from 5800-series AMD will also unleash the ATI Mobility Radeon HD 5700, ATI Mobility Radeon HD 5600 as well as ATI Radeon HD 5400 Series. All in an attempt to cover the whole of the mobile GPU market.

Like AMD's Radeon HD 5000 series of desktop market, there is also support for multiple monitors with Eyefinity and advanced video acceleration.

We can now expect a onslaught of laptops with AMD's new graphics chips, and according to AMD's own benchmarks must Mobility Radeon HD 5870 to be around 25% faster than Nvidia's fastest mobile GPU, GeForce GTX 280m. But when the numbers come from AMD itself, we'll take this with a large pinch of salt, while we are not really expected anything else.
