Nvidia NVDEC (formerly known as NVCUVID [1]) is a feature in its graphics cards that performs video decoding, offloading this compute-intensive task from the CPU. [2] NVDEC is a successor of PureVideo and is available in Kepler and later Nvidia GPUs. It is accompanied by NVENC for video encoding in Nvidia's Video Codec SDK. [2]
Downclocking means that using AVX in a mixed workload with an Intel processor can incur a frequency penalty. Avoiding the use of wide and heavy instructions help minimize the impact in these cases. AVX-512VL allows for using 256-bit or 128-bit operands in AVX-512 instructions, making it a sensible default for mixed loads. [69]
DDR and DDR2 memory is usually installed in single- or dual-channel configuration. DDR3 memory is installed in single-, dual-, tri-, and quad-channel configurations. Bit rates of multi-channel configurations are the product of the module bit-rate (given below) and the number of channels.
Nvidia claimed that both models outperformed its Maxwell-based Titan X model; the models incorporate GDDR5X and GDDR5 memory respectively, and use a 16 nm manufacturing process. The architecture also supports a new hardware feature known as simultaneous multi-projection (SMP), which is designed to improve the quality of multi-monitor and ...
Effective use of these improvements requires much more signal processing capability for compressing the video but has less impact on the amount of computation needed for decompression. HEVC was standardized by the Joint Collaborative Team on Video Coding (JCT-VC), a collaboration between the ISO/IEC MPEG and ITU-T Study Group 16 VCEG. The ISO ...
A memory leak can cause an increase in memory usage and performance run-time, and can negatively impact the user experience. [4] Eventually, in the worst case, too much of the available memory may become allocated and all or part of the system or device stops working correctly, the application fails, or the system slows down vastly due to ...
A 1982 Osborne Executive portable computer, with a 4 MHz 8-bit Zilog Z80 CPU, and a 2007 Apple iPhone with a 412 MHz 32-bit ARM11 CPU; the Executive has 100 times the weight, almost 500 times the volume, approximately 10 times the inflation-adjusted cost, and 1/100th the clock frequency of the smartphone.
March Algorithm - A class of algorithms used to test a computing device's memory. It consists of a sequence of operations applied to each memory cell before proceeding to the next one. March C+ algorithm - A memory testing algorithm. "The basic principle is to use finite state machines to read and write all the addresses one by one"
