According to Slashgear rumors, new Google tablet (expected to be introduced in Google conference June 2012, 27th-29th, together with introduction of new Android 5.0 Jelly Bean) wil be based on Samsung Exynos 5210 SoC.
If you are not familiar with Exynos chip family, remember that Samsung Exynos 5210 is an ARM Cortex-A15 implementation, providing 3.5 DMIPS/MHz.
Does this mean, that Asus is out of the game? Or does it just mean that Samsung Exynos CPU is used, and Asus is still expected to produce Google tablets?
In both cases, it means that Google Nexus tablet will be killer for most of chinese tablets at least from performance point of view. Raw performance of about 15000 DMIPS can not be matched by any of current China SoC producers.
As of now, most powerfull chinese chips used in tablets are dualcore Rockchip3066 and AmLogic AML8726-MX, ARM-Cortex-A9 implementations capable of up to 7500 DMPIS @1.6GHz and equippped with Mali-400 GPU.
