Nvidia NVENC (short for Nvidia Encoder) [1] is a feature in Nvidia graphics cards that performs video encoding, offloading this compute-intensive task from the CPU to a dedicated part of the GPU. It was introduced with the Kepler -based GeForce 600 series in March 2012 (GT 610, GT620 and GT630 is Fermi Architecture).
Driver 368.81 is the last driver to support Windows XP/Windows XP 64-bit. [citation needed] Windows XP 32-bit: 368.81 driver download; Windows XP 64-bit: 368.81 driver download; 32-bit drivers for 32-bit operating systems were discontinued after the release of driver 391.35 in March 2018. [99]
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]
In Windows ,the last driver to fully support CUDA with 64-Bit Compute Capability 3.5 for Kepler in Windows 7 and Windows 8.1 64-bit is 388.71, tested with latest CUDA-Z and GPU-Z, after that driver, the 64-Bit CUDA support becomes broken for GeForce 700 series GK110 with Kepler architecture.
NVENC is Nvidia's SIP block that performs video encoding, in a way similar to Intel's Quick Sync Video and AMD's VCE. NVENC is a power-efficient fixed-function pipeline that is able to take codecs, decode, preprocess, and encode H.264-based content. NVENC specification input formats are limited to H.264 output. But still, NVENC, through its ...
Nvidia's video encoder, NVENC, is 1.5 to 2 times faster than on Kepler-based GPUs meaning it can encode video at 6 to 8 times playback speed. [5] Nvidia also claims an 8 to 10 times performance increase in PureVideo Feature Set E video decoding due to the video decoder cache paired with increases in memory efficiency.
The hybrid implementation is significantly slower than the dedicated hardware in VP7's video-engine. The seventh generation PureVideo HD is sometimes called "PureVideo HD 7" or "VP7", although this is not an official Nvidia designation. This generation of PureVideo HD corresponds to Nvidia Feature Set F (or "VDPAU Feature Set F").
Nvidia's video encoder, NVENC, was upgraded to be 1.5 to 2 times faster than on Kepler-based GPUs, meaning it can encode video at six to eight times playback speed. [2] Nvidia also claims an eight to ten times performance increase in PureVideo Feature Set E video decoding due to the video decoder cache, paired with increases in memory efficiency.
