I'm in the process of installing in wall HDMI wiring (along with cat6A and Coax). Due to relatively long runs 40-60ft I'm focused on cables with Redmere technology. Through my research I have found there are 3 Redmere chips. MEA 1689, PRE 1692 (10.2gbps) and PRA 1700 (18gbps). Considering I want to future proof and ensure the cables can handle full true 4k (18gbps) then the only Redmere solution would be a cable with the PRA 1700 chipset. Unfortunately I have not been able to find any cables that have this chip. All the available high speed Redmere cables advertise a high band with but have the chip only capable of 10.2GBPS. In this scenario the chip is the limiting factor not the cable. So if I'm unable to find a cable with the PRA 1700 chip would it be best to use high end non Redmere cables on the short runs(40ft - 60ft) to ensure full bandwidth? From my understanding, the only benefit of Redmere technology is a thinner cable (easier for installs) and ability to bridge a longer run. As mentioned Redmere makes the PRA 1700 (18gbps) chip however I cannot find it in any HDMI cable in the market (maybe someone can).
