I have been thoroughly enjoying my , which I ordered only recently, and which I ordered because the actual tablet I have been using before, was only a first-generation .
Sometimes we obtain many new features, but also at the expense of losing some feature. Because the CPU is a RISC-Chip, the manufacturers of Android devices have sometimes made up for this by including a coprocessor called . is an SIMD – a Single-Instruction, Multiple-Data – coprocessor – aka a Vector-Processor, which is often useful to allow the decoding of high-definition video streams in real-time, without placing the burden of doing so on the main CPU.
(Edit 04/08/2017 : I have given my own definition of what “Hardware Acceleration” means, Here. )
What has happened with the Pixel C, is that Google has decided to put a CPU into it, which is an SoC that also has a big coprocessor – its mighty GPU. With this tablet, real-time video-decoding is meant to be performed by the GPU, which advertizes several system-installed Codecs. Therefore, watching videos in high definition should not require a coprocessor, and the does not have one. (And, when I scroll further down the list of Codecs, that list includes two of the corresponding Encoders, from , not only the Decoders. )
In fact, the only has a 4-core main CPU!
