Difference b/w Intel 4th generation and 3rd generation processors

Ramakrishna    June 16, 2013    Comparison , Intel , processor   

Intel had recently announced new series of their processor, the 4th generation Intel i3, i5, i7 processors. The previous version of Intel i3, i5, i7 processors are build by 32nm microarchitecture. The new processors are build by 22nm microarchitecture, main differences in the generations is intel processors is shrinking of sizes of die in nano scaling. These 22nm 4th generation processors are codename "Haswell". On June 4th, 2013. Intel had officially announced new CPUs with 4th generation Haswell processors at Computex Taipei 2013.

The 3rd generation is called "Ivy Bridge," and is basically a copy of Sandy Bridge manufactured on a smaller scale, or die. However, Intel also focused on beefing up the integrated graphics in this processor. Haswell processors are based on 22nm technology support up to 4 cores / 8 threads at 2.4GHz and 6 MB last level cache boosting computing performance while enabling the latest virtualization techniques and CPU enhancements. Onboard soldered low voltage DRAM with ECC is supported for maximum reliability and optional memory expansion via an SODIMM socket extends the capacity to up to 16GB for the most demanding applications in high performance or virtualized environments. Dual channel design and memory speeds up to 1600 MT/s along with increased cache size and enhanced cache algorithms guarantee maximum memory performance and some efficiency features, faster memory controller, a improved Integrated GPU, some new instruction sets and chipset additions and supports.

Motherboard built with sockets LGA 1150, rPGA 947 and BGA-1364 supports new Haswell processors.

Finally words:

Without get very technical, the primary differences for the average person are relatively small.

• Haswell consumes very less power; such It can run a new MacBook for more than 12 hours (full day). - via


• Slightly more processing power. On average with the same clock speeds Haswell CPUs are faster than 3rd generation CPUs.

Haswell is just perfect, Perfect computing, Perfect Battery life and Perfect inbuilt Perfect Graphics (IRIS Graphics).
