Exynos 5250 benchmarks are pathetic!
Both CPU and GPU results are disappointing. The same SoC when used in Chromebook runs SunSpider in about 650ms. It's double while running Android 4.2. That's pretty bad. It's worse than Exynos 4 running in Note 2. SunSpider is single threaded, so extra cores in Exynos 4 has no effect.
GPU is just average, infact much worse than A5X GPU. I can say that with such numbers and such insane resolution, the tablet will be a complete lagfest.
Maybe firmware is not updated, but results are truly horrendous now.
