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.
