Yesterday, Samsung announced the new Exynos 5 Octa (Exynos 5420) chip based on ARM Mali-T628 silicon. The new AP is 20 percent more faster than its predecessor (Exynos 5410), claims Samsung. However, the most significant change is the graphics processing unit, it's the industry's first SoC to feature a six-core GPU.
Engadget got some hands-on with a prototype device featuring the new Exynos 5420 SoC over at SIGGRAPH 2013. Samsung put the prototype up against a Nexus 10 in a benchmark fight, and the prototype crushed it! Currently, Nexus 10 is the only device to pack the most powerful GPU, packing an Exynos 5 Dual (5250) SoC with Mali-T604 GPU, so comparing the Exynos 5420-packed prototype with a Nexus 10 was certainly the right choice.
As you can see from the video, the prototype scored almost double the points as of the Nexus 10. During the benchmark, the prototype was smooth as silk with no issues whatsoever, while the Nexus 10 was a struggling. We are looking forward to seeing the new Exynos 5420 go up against the Exynos 5410 and the Snapdragon 800 SoCs.
