Sandy Bridge Vs Ivy Bridge
Intel Sandy Bridge Vs Ivy Bridge
The Ivy Bridge shrinks the die from 32 nm in Sandy Bridge to 22 nm, which reduces the power consumption per transistor enabling lower power and higher clock frequency possible. The processor section of the Chip is does not see any significant change.
On the integrated graphics side Intel has made significant improvement attempting to bridge the gap that existed in the HD Graphics 3000 in the Sandy Bridge and the Llano processors. For the first time we will see the Direct X 11 and shader 5.0 support in the Ivy Bridge processors. The number of cores / shaders has been increased giving close to 2x performance improvement in the integrated graphics
The processing technology will use the Tri Gate Transistor technology for the first time. Intel has taken a decisive lead in the use of Tri Gate and it will be hard for others to catch up. The technology will also enable Intel in the area of low power Atom processors for Tablet processors.
Table 1 : Intel Sandy Bridge Vs Ivy Bridge
| Feature | Sandy Bridge |
Ivy Bridge |
| Tri Gate Transistors |
No | Yes |
| Improvement in processor section for same clock |
– | 10% performance improvement |
| Direct X Support in Integrated Graphics |
DirectX 10.1, Shader 4.1 | DirectX 11, Shader 5.0 |
| Lithography | 32 nm | 22 nm |
| Improvement in Graphics Performance |
– | ~100% |
Since the Ivy Bridge processors can scale higher clock frequency, it will have an official support for higher unlockable frequency. It will certainly be a delight for the overclockers.
The Ivy Bridge graphics will have dedicated L3 Cache which helps in improving the GPU performance.
