Vivante Gets Top Score in YOUi Labs GPU Quality Calibration Suite for Rendering Accuracy

Vivante tops Imagination Technologies SGX544 and ARM Mali 400-MP4/T604 in image quality tests to become an industry standard mobile reference platform

SUNNYVALE, Calif., April 17, 2013 /PRNewswire/ -- Vivante Corporation, a world-wide leader in graphics and compute technologies, announced that YOUi Labs™, an independent Natural User Interface (NUI) and professional services firm that puts visually inspiring and responsive user experiences on interactive TVs, smartphones, and tablets, has given two thumbs up to the GC4000 in image rendering precision and correctness. The GPUs with the highest rendering quality and computational fidelity drive amazing user experiences that make devices fun and interactive.






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. Products compared in their QA labs alongside the GC4000 include 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. Compared to all products, the Vivante GC4000 came at the top in accuracy with no artifact or rendering errors, and even surpassed the results of the discrete mobile GPU.

"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. 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 the full range of Vivante's mass market and mainstream offerings, including the smallest licensable OpenGL ES 3.0 core* at 3.5 mm2 (total silicon footprint 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. The results of this test and others evaluating mobile GPU IP shows we made the correct decision in our architecture. We look forward to building on our strengths and innovating-the-future of visual user experiences and 3D graphics," said Wei-Jin Dai, President and CEO of Vivante Corporation.
