According to PhoneArena, Samsung is preparing more than the still unannounced Exynos 5250 System-on-Chip.
In fact, the company is building something called the Exynos 5450, a quad-core platform operating at 2GHz (the cores themselves are Cortex-A15).
The report also mentions the Mali-658 as the graphics processing unit.
It is quite possible, as the report speculates, that Samsung will use the Exynos 5450 in its Windows 8 tablets.
One can only wonder what capabilities those things will have, knowing that the Exynox 5250 already has what it takes to handle an 11.6-inch display, with a resolution of 2,560 x 1,600 pixels.
It will also be interesting to see how this platform faces down the NVIDIA Tegra 3 and whatever other competitors decided to rear their heads by the time Microsoft's new OS is completed.
