Advanced Micro Devices' (NASDAQ: AMD) fourth-quarter report, set to be released after the market closes on Tuesday, will be the last quarterly report prior to the launch of its highly anticipated new products. Ryzen, its upcoming high-end CPU, will launch sometime during the first quarter, and Vega, its new high-end GPU, is set for some time during the first half.[...] We don't know much else about Ryzen. Only the eight-core version has been shown off so far, and pricing is still a mystery. Given AMD's weak position in the CPU industry, I would expect aggressive pricing from the company. Intel certainly has room to lower prices if necessary, so it will be interesting to see how disruptive Ryzen ends up. Investors should listen for any new Ryzen information during the company's earnings conference call.
