Just yesterday, Samsung announced their next generation of Exynos 5 Octa Core processors, the Exynos 5 Octa 5420 SoC. The new chip is designed to be even more powerful especially in graphics. It is said to be 20% faster for general processing, but will be twice as fast in graphics as the previous Exynos 5 Octa. Here's a few more details about this new chip.
  • Features a quad-core ARM Cortex-A15′s clocked at 1.8GHz
  • Four “smaller” Cortex A7 cores clocked at 1.3GHz are included in the big.LITTLE configuration
  • Features a new six-core Mali-T628 MP6 GPU
  • Includes dual-channel LPDDR3 clocked to 933MHz, providing 14.9GBps of memory bandwidth
  • Support for full HD WiFi display
  • Also includes multiple image compression (MIC) for pictures and video (the processor can display them easier so there is less battery drain)

The new chip has already been benchmarked versus some previous gen tech. The folks at Engadget had a new reference Samsung tablet with the new chipset in it and compared it to the Nexus 10 which sports 1.7GHz Exynos 5 Dual 5250. According to them the new technology ran all of their demos and benchmarks a great deal smoother. Here's a quote with the details,

Before the exhibitions start officially, we had a chance to nab a look at a reference tablet running the Exynos 5 Octa 5420 SoC alongside ARM's Mali T-628 silicon packing six cores. For comparison purposes, the prototype unit was matched against a Nexus 10 tablet and its 1.7GHz Exynos 5 Dual 5250. Our first impression? The 5420 ran GLBenchmark's 2.7.0 T-Rex on-screen test noticeably (read: a lot) smoother than the Nexus 10 and the final scores confirmed the performance boost that we previously reported. We also had a look at both the Unreal Engine's Citadel (up to 45fps at times) and Unity Chase on the test device with both further demonstrating silky smooth transitions and brisk graphic renders. There's no word on when the chip will make it into your next mobile device, but it is scheduled to go into production next month.
