Intel Sandy Bridge Technology
[attachment=27795]
INTRODUCTION
2nd Generation architecture for PC and Servers
CPU and GPU are fused together on single chip
Significant advances in visual and 3D graphics capabilities
New Intel® Advanced Vector Extensions(AVX) instructions for enhanced floating point intensive application performance
New 32nm Intel microarchitecture
Optimized Intel® Turbo Boost Technology and Intel® Hyper-Threading Technology
Turbo Mode
Sandy Bridge takes a different view of turbo boost
Focusing on die temperature rather than instantaneous power dissipation
Once the chip reaches its maximum operating temperature, it must throttle back to its rated TDP level to avoid overheating
The integration of GPU and CPUs on one chip creates additional turbo opportunities
If the GPU is not in use or is operating at a low speed, the power manager can assign some of its thermal budget to the CPUs
Speedup PC users upto 40%
