With such good scores coming out of ARM chips these days, what's the point of x86 and x64 again?

There are two problems with the reported Exynos 2100 benchmark numbers, here. First, a quick check of similar reports suggests that there are two Exynos flagship SoCs about the place and that the Exynos 2100 is the lesser performer of the two. These high benchmark scores don't sit well with the information in these other reports. Second, ARM's projected performance numbers for forthcoming cores are often right on the money. What these Exynos numbers show is an X1 core that is clipping along at a rate that is a good deal faster than ARM has indicated we might expect. Of course, performance like that is possible but it isn't especially likely.

It will still be garbage for emulation... It sucks being stuck with this inferior version of the phones.

Just having high CPU/GPU score wi]ll not do, Snpadragon beats it in every parameters be it battery life, image processing, network quality, thermals among others and yes you heard it right Galaxy with Spadragon has better image quality than Exynos variant, if Exyons can beat Snapdraging in all these parameters then only it will be truly worthy of the crown, else I'll pass their next Galaxy (Exynos) device.

Funny how after a back and forth between 3 and 4 digit naming they've settled at "2100". It says entry, "kiddy sized", whatever way you look at it.
