Korean giant Samsung has announced a new-and-improved Exynos 5 Octa called the Samsung Exynos 5 Octa (Exynos 5420) that comes with greater CPU speed and double the graphics core performance of its previous release powering some Galaxy S4 smartphones.
The new Exynos 5420 will pair four Cortex A15 cores topping 1.8GHz with four Cortex A7 cores clocking at up to 1.3GHz in a single-chip design alongside a brand-new graphics engine from chip designer ARM – the Mali-T628 graphics core.
ARM announced the new GPU design in 2012 but Samsung appears it’ll be the first to bring the technology to market. The new graphics engine will be based on the six-core Mali-T628 MP6 design, said to deliver twice the graphics performance of the Mali-400 MP4. The new graphics engine is also capable of driving higher resolution displays, up to 2560×1600-pixel resolution.
Further CPU speed improvements also come through faster RAM with new dual-channel LPDDR3 RAM running at 933MHz. It also has support for GPGPU (general-purpose computing on graphics processor units) thanks to OpenCL 1.1 and OpenGL ES 3.0. We can only imagine what the heat production would be like if it were possible to run all 14 cores (4 x A15, 4 x A7, 6 x Mali-T628) at the same time…
Samsung is also talking up the CPU’s video acceleration capabilities with “a variety of full HD 60 frames per second video hardware codec engines for 1080p video recording and playback.”
According to the Samsung announcement and engadget, mass production of the Exynos 5420 is expected to begin in August.
