AMD has introduced the mobile counterpart to its DirectX 11-ready desktop graphics cards. The Mobility Radeon HD 5000 series is comprised of three different graphics chips that span the usual markets: mainstream, performance, and enthusiast. The Tech Report has compiled a table with the new GPUs, which should make the information a little easier to digest:

  Mobility Radeon
HD 5400 series
Mobility Radeon
HD 5600 & 5700 series
Mobility Radeon
HD 5800 series
Transistors 242 million 626 million 1.04 billion
Stream processors 80 400 800
Core frequency 750MHz 650MHz 700MHz
Shader arithmetic 120 GFLOPS 572 GFLOPS 1.12 TFLOPS
Memory data rate 3.2 Gbps (GDDR5) 3.2 Gbps (GDDR5) 4 Gbps (GDDR5)
Memory bus 64-bit 128-bit 128-bit

It's worth noting that none of the GPUs are based on Cypress, which AMD claims is too hot and large for notebooks. The 5400 line is based on Cedar, the 5600 and 5700 chips are built on Redwood, and the 5800 series uses the same 40nm Juniper technology as the Radeon HD 5700 desktop cards. All of the Mobility Radeon HD 5000 cards support up to 1GB of GDDR5 RAM and hexa-displays -- except the 5400 parts, which can "only" handle quad-display setups.

The company also announced that it has shipped two million DirectX 11-capable graphics processors, and you'll be pleased to know that TSMC's 40nm issues are a thing of the past, so AMD's DX11 products should be landing in stores and systems near you.
