(iTers News) -Vivante Corporation turned out to be the best performer in the GPU image quality test of YOUi Labs, an independent Natural User Interface and professional services firm. The YOUi Labs test stresses GPU shader floating point accuracy since it is critical to smooth and fluid NUIs that blend visually rich graphics content with gesture.

Vivante’s GC4000 outperformed all rival GPU core IPs in the accuracy benchmark test with no artifact or rendering errors, and even surpassed the results of the discrete mobile GPU.

Put to the test was Nvidia's Tegra 3, Imagination's SGX544, ARM's Mali-400 MP4, ARM's Mali-T604, Qualcomm's Adreno 225, and a reference discrete GPU based on Nvidia's GeForce GT 630M.

With the highest rendering quality and computational fidelity, GPUs are traditionally very instrumental in driving amazing user experiences that make devices fun and interactive.

"Rendering accuracy based on GPU shader precision is one critical area where GPU vendors can differentiate themselves from the rest of the pack," stated Dr. Jon Peddie, of Jon Peddie Research, the industry's market research firm.

"Modern mobile GPUs have transitioned into fully programmable processors using the latest graphics APIs and high-level shading languages, which can showcase unlimited rendering effects. Added he, ”However, even though products follow the same standard API specification, they are not created equal due to variations in shader design. Therefore, it is good to see a company like YOUi Labs help standardize the testing process with their GPU compatibility and quality test suite. This brings real value to the marketplace and consumer."

Floating point accuracy and performance is extremely important for image quality, shader-based user interfaces, 3D game rendering using the latest OpenGL ES or DirectX APIs, and GPU Compute using OpenCL or native Renderscript/Filterscript for vision processing in consumer and embedded devices.

The same GC4000 shader core and unified driver stack scales across a full range of Vivante's mass market and mainstream offerings. They include the smallest licensable OpenGL ES 3.0 core that has total silicon footprint of 3.5 mm2 using TSMC 40nm LP, and the latest extreme performance multicore GPU IPs like the released GC6000 Series and upcoming GC7000 Series targeting 14nm/16nm FinFET production.

"The YOUi Labs test result further demonstrates our commitment to delivering products that focus on rendering accuracy, quality, and innovation. From the beginning, we defined image quality and performance as two of the most important attributes in our GPUs and made sure they deliver the most life-like graphics to differentiate our products in the mobile GPU space, “ said Wei-Jin Dai, president and CEO of Vivante Corporation.
