Tick-Tock is a model developed by Ashwani Gupta of Jones Farm 5 ( Hillsboro, Oregon) which has been adopted by Intel Corporation since 2007 to follow every microarchitectural change with a die-shrink of the process technology. Every ‘tick’ is a shrinking of the process technology of the previous microarchitecture and every ‘tock’ is a new microarchitecture. cessor can be overclocked for higher performance—useful for gaming en a mobile platform.
Sandy Bridge is, in fact, a major tock. The architecture underwent a major platform repartitioning with a lot of things being integrated on the die. For instance, the clock generator and the integrated graphics processor now share space with the CPU. All this integration results in extremely low power consumption. The on-die graphics processor called Intel HD Graphics delivers a below par performance, but improved power-gated GPU. This made Sandy Bridge the best option for portable PCs.
Sandy Bridge was released
Intel’s 22nm die- shrink of Sandy Bridge is codenamed Ivy Bridge. Apart from the die-shrink, Intel has utilised a non-planar architecture called tri- gate for the transistor in transistors, this technology is claimed to allow the processors to cut power consumption by half and perform 37 per cent faster. Performance wise, the CPU is expected to outperform Sandy
From Fig. 3, you can see that Intel HD Graphics processor in Ivy Bridge significantly outperforms those in Sandy Bridge processors.
Although Intel factories had to be upgraded to be able to manufacture these tri-gate Ivy Bridge CPUs, the market prices remain roughly the same per cent more.
Ivy Bridge also overcomes the shortcomings of the previous line of processors by improving on the graphics processing capabilities. The Intel HD Graphics in Ivy Bridge supports DirectX 11, OpenGL 3.1 and OpenCL 1.1, while also outnumbering the executing units by four to per cent better than the previousgeneration Intel HD Graphics. Intel HD Graphics in Ivy Bridge comes in for better performance.
- in a 15 per cent reduction in power
Ivy Bridge was released in April this year. Upgrading to Ivy Bridge would be a straightforward affair since both Ivy and Sandy use the same LGA 1155 socket.
Haswell: The next tock
Haswell is the codename for Intel’s next microarchitecture which forms Similar to Ivy Bridge, Haswell is based on the 22nm manufacturing process using tri-gate technology. This processor is not backward-compatible Bridge and Sandy Bridge use the LGA 1155 socket. So to get a Haswell mi-
