Intel Core i5-2430M is latest addition to Intel’s Core i5 Sandy Bridge mobile processors. It is a worthy successor to its previous model, Intel core i5-2410M. Besides clock speed and implementation of AES, there are no significant differences between these two processors. Both belong to Sandy Bridge Core i5 family and are intended for mid-level notebooks and laptops. Core i5-2430M was launched at Q4 2011, much later than i5-2410M. Here are more details about the processor –
Intel i5-2430M is a dual core processor and operates with 2.4GHz frequency. Due to the presence of Turbo Boost Technology 2.0, the frequency can boost up to 3.0GHz. However, overclocking depends on number of factors which are as follows-
As per Intel, the Turbo Boost Technology 2.0 is triggered when the Operating System needs the highest processor performance and depends on following factors :
- Number of active cores
- Estimated usage of current
- Estimated usage of power
- Temperature of the processor
If the processor is working below these limits and applications demand additional performance, then the frequency of the processor will rises up dynamically to maximum limit.
Intel core i5-2430M also comes with Hyper Threading technology, which enables each core to run two threads simultaneously.
3MB of smart cache is associated with the processor .The cache memory can be shared by both, processor cores and graphics. We have also seen 3MB of smart cache in 1st generation of processors, but in that case, graphics was not able to share cache memory. The instruction set is 64 bit and it fits into PPGA988 socket. Maximum TDP of the processor is 35 watt.
Core i5-2430M is fabricated with 32nm technology and the processor die itself houses graphics, so graphics is also fabricated with 32nm. The graphics is known as Intel HD 3000 graphics, which operates with 650MHz frequency, and can Turbo Boost up to 1.2GHz. The graphics supports HDMI, DVI and dual display and it is capable of decoding HD videos. The graphics can be comparable with any entry level dedicated graphics.
Intel core i5-2430M also comes with integrated dual channel memory controller. It supports a maximum of 16GB memory. It supports DDR3-1066 and DDR3-1333 memory speed grade. It connects with other chipsets through DMI which transfer data of 5GT/s
Intel core i5-2430M is incorporated with advanced technologies like Virtualization and AES New instruction. AES New instruction comprises of seven new instructions. This works faster and provides affordable data protection with enhanced security. It makes ubiquitous encryption possible in areas where it was earlier unachievable. It makes your data safe from malicious attacks. However, Intel Core i5-2410M is devoid of AES new instruction.
The passmark score for core i3-2430M is 3304, at the time of publishing the article. Windows 7 experience index is 4.5 ( user given ).
