Exynos 5 Octa 5420: Is This Samsung’s Fastest Chip ?


Today Samsung Released the Exynos 5 Octa chip Which it will be soon using in the up coming smartphones. The Exynos 5420 is a refreshed version of the Exynos 5 Octa that brings higher clock speeds, a new GPU, and, hopefully, a functional cache system that would allow the chip to truly make use of the big.LITTLE design.

Announced today, Exynos 5420 features the same four core clusters, with A7 cores running at up to 1.3GHz and A15 cores running at up to 1.8GHz. That’s, in both cases, 100MHz more than the previous generation. According to Samsung, the new CPU offers 20 percent “better performance over the predecessor by optimizing the power-saving design”


Another big change is the replacement of the Imagination PowerVR SGX544MP3 GPU found on the Exynos 5410 with an ARM Mali-T628 MP6 GPU. The new six-core processor is capable of General-Purpose computing on Graphics Processing Units (GPGPU), which is a technology that enables the GPU to take over some complex computing tasks from the CPU, OpenGL ES 3.0, and Full Profile Opencl 1.1.

The new GPU will bring a remarkable improvement in the performance of graphics as compared to the rather old PowerVR GPU of the earlier generation. Samsung claims that the graphics performance capabilities of the new SoC are “two times greater” than the old one, which is a bit vague, but not unreasonable to believe.
