Intel's Haswell GPU: Turbocharged and more Video Features
The integrated graphics units of the next-generation Core i processor Haswell will perform much better than their current Ivy Bridge predecessors, support DirectX 11.1 and bring a whole new set of video features. The Intel has been known in the IDF. The Haswell GPU will be available in three versions: GT1, GT2 and GT3. All versions are also universal calculations via OpenCL 1.2 capable - yet the Ivy Bridge GPUs support in conjunction with the Intel OpenCL 1.1 SDK only.
GT1 and GT2 have, according to the published architecture diagrams compared to Ivy Bridge GPU cluster with a second shader cores (execution units / ES). How much per block ES cluster Intel actually is unclear. Even more powerful GT3 should be by the second rasterizer and four instead of two shader clusters. These additional units may GT3 off idle, in order to minimize power consumption.
In addition to the shaders is also doubled the size of shared buffer memory and the number of texture units. This should handle certain texture formats up to four times faster than the Ivy Bridge GPUs called HD 2500 or HD 4000th
To the higher number of functional units on the GT3 fast enough to provide data, Intel has doubled the performance of most fixed-function units in the geometry of the 3D pipeline. These improvements also the variants GT1 and GT2 used to benefit. In addition, the command generator (Command Streamer) was complemented by a resource Streamer to feed the units more efficient and thus accelerate the rendering of 3D scenes.
Moreover, Intel leads the Video Quality Engine (VQE) as the sixth block of the GPU. She is responsible for the frame-rate conversion (frame rate conversion) and entwackelt videos. AMD Steady Video offers a similar feature since the year 2011 for Radeon graphics cards and processors APU combo. In addition, over VQE run some new features to beautify (HD) videos such as correcting skin tones and color gamut expansion.
Haswell hardware video transcoder Quick Sync to convert videos faster. The hardware decoder MFX also processes the Motion JPEG (MJPEG), as is common in conventional webcam sessions. Moreover MFX now encoded MPEG-2 content in real-time and decodes different video quality levels of a SVC stream (Scalable Video Coding). This is for professional video conferences with many participants thought of different bandwidths. As an innovation, Intel also praises the play of 4K x 2K Video. This should already dominate the Ivy Bridge MFX unit, which in our tests, but never worked.
Intel rumored to want the GT3 GPU also use Wide-I/O-Speicher that could increase the data transfer rate drastically.
