MediaTek Announces ten-core Helio X23 and X27 mobile processors
Mobile chipset maker, MediaTek, just announced two new deca-core processors. The X23 and X27 mobile processors now provide better balance between power saving and performance by placing three different types of core on one chipset. The chipset manufacturer has been developing interesting solutions to provide better parallel computing performance on mobile devices. Back in 2014, MediaTek developed the MT-6595, an octa-core chipset that gave the company much exposure. After that, even Qualcomm started releasing octa-core chipsets.
How multi-core works on mobile
In desktop and laptop processors (rather, non-mobile processors), all the four, six, or eight cores work all at once. The performance of these processors can scale dynamically based on work loads. The processor can overclock or underclock as required.
In mobile, all the eight or ten cores do not work together simultaneously. This is to save power. Also, most common mobile applications cannot use more than one or two cores at once. So, the processors contain different cores of different specifications which are used based on the needs.
MediaTek 10-core architecture
The 10-core architecture by MediaTek is based on the ARM’s big.LITTLE design. In this design, the cores are organized into three clusters. A high performance cluster consists of two A72 cores of 2.5GHz. A performance/power-saving cluster contains four 2.0GHz A53 cores and finally, a power saving cluster is made out of four 1.4GHz A53 cores. You can check out the diagram to get a better understanding.
Both the new processors are based on the older X20 and X25 10-core chipset.
- The Helio X23 is based on the Helio X20 and raises the clock speed of the ARM Cortex-A72 cores from 2.1GHz to 2.3Ghz.
- The Helio X27 is based on the Helio X25 and raises the clock speed of the ARM Cortex-A72 cores from 2.5GHz to 2.6GHz. The ARM Mali-T880MP4 GPU on the X27 was also raised to 875MHz from 850MHz.
