Samsung took the wraps off a new Octa chip yesterday, the Exynos 5420, which brings higher clock speeds, a new and powerful GPU, and, all signs indicate, a fix to the bug that crippled the performance of the first Octa chip, Exynos 5410.
The Korean manufacturer highlighted in the press release the performance improvements that the new Exynos 5 Octa offers over the model that was first introduced in January, and especially the graphics prowess of the ARM Mali powered chip.
Folks at Engadget visited the SIGGRAPH 2013 trade show where they got the chance to compare a 10-inch reference tablet powered by the new Exynos 5420 chip with the Nexus 10, powered by a dual-core Exynos 5 Dual processor codenamed 5250. Both devices were set up to run the same benchmarks, and suffice to say you don’t have to be an expert to tell them apart. For the record, both devices have the same resolution of 2560 x 1600.
The benchmark used is the T-Rex test from the GLBenchmark 2.7.0 suite, which is designed to assess the graphical computation capabilities of mobile systems on a chip. The two competing GPUs are an ARM Mali T-628 in the case of the Octa and an ARM Mali T-604 in the case of the older Dual.
While it’s trivial that new tech is better than old tech, the Exynos 5 Dual is still a modern, highly-capable piece of silicon. The fact that the new Exynos 5 Octa outpaces it so categorically speaks volumes about the advancements in GPU tech that ARM and Samsung made over the past year. We look forward to see how the ARM Mali T-628 GPU does against the Imagination PowerVR SGX544MP3 GPU inside the first Exynos 5 Octa chip, the 5410.
Samsung says the Exynos 5420 is currently being sampled to clients and that mass manufacturing should begin in August. That means that mobile gamers will get to try out the first devices powered by new Exynos 5 Dual, including smartphones, tablets, and Chromebooks, starting this fall.
