The budget chip maker makes processors for Android tablets, TV boxes, and other devices and they have not been that bad.

Last year the company's RK3288 ARM Cortex-A17 quad-core processor stepped up the game with some strong performance.

However, this year Rockchip launched its first 64-bit, octa-core chip. Dubbed the RK3368, the chip was an ARM Cortex-A53 processor with PowerVR G6110 graphics

Unfortunately, some of the benchmarks seem to indicate you would be better off buying last year's chip instead.

CNX Software ran a series of benchmarks on the RK3368 and RK3288 processors and found that in most tests, the older processor did much better.

While the new chip is based on newer ARMv8 technology it is clocked lower and has PowerVR G6110 graphics instead of ARM Mali-T764 graphics. This means that it scores a little lower in the AnTuTu benchmark, and far lower in the Vellamo and 3DMark tests.
So far the chip has not been seen in any of Rockchip's gear outside China but it might be that it is better you give them a miss, particularly if the older part is cheaper.

CNX Software said that Rockchip's new processor does have some advantages over the old chip. It supports Android 5.1 Lollipop and it's supposed to support 4K, 60 Hz video decoding, although the latter does not seem to work that well.
