The GeForce 700 Series is a family of graphics processing units developed by Nvidia, used in desktop and laptop PCs. It is mainly based on a refresh of the Kepler microarchitecture (GK-codenamed chips) used in the previous GeForce 600 Series, but also includes cards based on the previous Fermi (GF) and later Maxwell (GM) architectures. A number of GeForce 700 series chips were released for mobile devices in April 2013. GeForce 700 series cards were first released in May 2013, starting with the release of the GeForce GTX Titan on February 19, 2013, and the GeForce GTX 780 on May 23, 2013. == Overview == GK110 has been designed and is being marketed with computational performance in mind. It contains 7.1 billion transistors. This model also attempts to maximise energy efficiency through the execution of as many tasks as possible in parallel according to the capabilities of its streaming processors. With GK110, increases in memory space and bandwidth for both the register file and the L2 cache over previous models, are seen. At the SMX level, GK110's register file space has increased to 256KB composed of 65K 32bit registers, as compared to Fermi's 33K 32bit registers totaling 128 KB. As for the L2 cache, GK110 L2 cache space increased by up to 1.5MB, 2x as big as GF110. Both the L2 cache and register file bandwidth have also doubled. Performance in register-starved scenarios is also improved as there are more registers available to each thread. This goes in hand with an increase of total number of registers each thread can address, moving from 63 registers per thread to 255 registers per thread with GK110. With GK110, Nvidia also reworked the GPU texture cache to be used for compute. With 48KB in size, in compute the texture cache becomes a read-only cache, specializing in unaligned memory access workloads. Furthermore error detection capabilities have been added to make it safer for use with workloads that rely on ECC.〔(【引用サイトリンク】 title=NVIDIA Launches Tesla K20 & K20X: GK110 Arrives At Last )〕 This series will support DirectX 12.〔http://blogs.nvidia.com/blog/2014/03/20/directx-12/〕 Dynamic Super Resolution(DSR) was added to Kepler GPUs with the latest Nvidia drivers.〔http://www.geforce.com/whats-new/articles/geforce-344-48-whql-driver-released〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「GeForce 700 series」の詳細全文を読む スポンサード リンク
