comprising 8 Jaguar cores, 1152 GCN shader processors and AMD TrueAudio. Product teardowns later confirmed the implementation of 4 Gb based GDDR5 memory in the PlayStation 4. In February 2014, as a result of its acquisition of Elpida, Micron Technology added 2 Gb and 4 Gb GDDR5 products into the company's portfolio of graphics memory solutions. As of January 15, 2015, Samsung announced in a press release that it had begun mass production of "8 Gb" (8 × 10243 bits) GDDR5 memory chips based on a 20 nm fabrication process. To meet the demand of higher resolution displays (such as 4K) becoming more mainstream, higher density chips are required in order to facilitate larger frame buffers for graphically intensive computation, namely PC gaming and other 3D rendering. Increased bandwidth of the new high-density modules equates to 8 Gbit/s per pin × 170 pins on the BGA package x 32-bits per I/O cycle, or 256 Gbit/s effective bandwidth per chip. On January 6, 2015, Micron Technology President Mark Adams announced the successful sampling of 8 Gb GDDR5 on the company's fiscal Q1-2015 earnings call. The company then announced, on January 25, 2015, that it had begun commercial shipments of GDDR5 using a 20 nm process technology. The formal announcement of Micron's 8 Gb GDDR5 appeared in the form of a blog post by Kristopher Kido on the company's website September 1, 2015. GDDR5X In January 2016, JEDEC standardized GDDR5X SGRAM. GDDR5X targets a transfer rate of 10 to 14 Gbit/s per pin, twice that of GDDR5. Essentially, it provides the memory controller the option to use either a double data rate mode that has a prefetch of 8n, or a quad data rate mode that has a prefetch of 16n. GDDR5 only has a double data rate mode that has an 8n prefetch. GDDR5X also uses 190 pins per chip (190 BGA). By comparison, standard GDDR5 has 170 pins per chip; (170 BGA). It therefore requires a modified PCB. GDDR5X commercialization Micron Technology began sampling GDDR5X chips in March 2016, and began mass production in May 2016. Nvidia officially announced the first graphics card using GDDR5X, the Pascal-based GeForce GTX 1080 on May 6, 2016. Later, the second graphics card to use GDDR5X, the Nvidia Titan X on July 21, 2016, the GeForce GTX 1080 Ti on February 28, 2017, and Nvidia Titan Xp on April 6, 2017. See also List
