Karolina Miller is an editor for VC Studio. From video/audio downloading to DVD creating and converting, she knows them all. And she likes sharing her thought and solution about multimedia.

Hardware acceleration, is mainly talking about the use of GPU (Graphics processing unit) together with a CPU to enhance the computer hardware performance. When it applied by a software, it can dramatically increase the speed and performance of the task such as video encoding/decoding or playback while lowering the CPU load at the same time. At present, the common GPU acceleration platforms are NVIDIA CUDA, NVENC, AMD APP and Intel Quick Sync. We will show you what are they and how they make changes on video transcoding.

Part 1 Four Type of Hardware Acceleration

NVIDIA CUDA Acceleration

CUDA, the abbreviation of Computer Unified Device Architecture, is a technology invented by NVIDIA that allows to perform massive parallel computing on NVIDA GPU chips and thus on graphics cards that leverage these chips. The basic idea for CUDA is to use the power of Graphical Process Unit (GPU) to provide better computer performance for solving complex problem. CUDA is outstanding platform which allows to direct accessing to GPU'S parallel computational elements and virtual instruction set for the execution of compute kernels.

NVENC

In March 2012, NVIDIA NVENC is introduced with Kepler-based GeForce 600 series as a powerful video encoding technology by NVIDIA. It is the successor of CUDA which is designed to use NVIDIA graphics cards to encode the stream instead of CPU. Compared with the CUDA-based encoders, the main advantage of NVENC is that GPU-based NVENC has the faster speed and less power consumption.

AMD APP Acceleration

AMD APP means AMD Accelerated Parallel Processing, which aims to improve the video quality and enhance application performance. It is a set of advanced hardware and software technologies that works on the cooperation between graphics processors (GPUs) and CPU. So it can execute heterogeneously to accelerate many applications beyond just graphics by making the GPU and CUP play their own advantages perfectly. This can build a better and balanced platform to finish the high-demanding compute tasks, thus provide a better application experience to the end users.

Intel Quick Sync Video

Intel Quick Sync, a breakthrough hardware technology integrated into some of its CPU's which is used for video encoding and decoding. Intel Quick Sync Video uses the dedicated media processing capabilities of Intel Graphics Technology to make fast decoding and encoding, while also enabling the processor to complete other tasks, providing excellent PC performance and responsiveness.

Simple Comparison

The most intuitive impact for ordinary consumers about GPU acceleration is the application on video transcoding. NVIDIA, AMD and Intel has its own acceleration technology for improving the speed and video quality. From below picture, you will know the key factor which can affect the frame quality is the software rather than the platform. For the conversion speed, it also depends on many factors like software, computer performance, etc. But it absolutely works faster than the CPU only.

Part 3 What Video Converter Supports Hardware Acceleration

Currently, the hardware acceleration is widely used with video software such as converter, player and editor. Most of the video software can only support NVIDIA, while few program support AMD. But here we would like to recommend Video Converter Ultimate, which supports four technologies we mentioned above and perfectly supports multithreading and multicore to make it become the fastest Video Converter in the market.


Video Converter Ultimate now can convert video with 30X faster speed by making most of multi-core processor and the Intel Core, NVIDIA CUDA/NVENC, AMD technologies, while preserving the optimum video quality. This program automatically finds your computer's multi-core processor to take full advantage of your computer's spare power. So as to enable you to convert multiple videos simultaneously, making quick work of the task of batch video conversions.
