For the very first time, ARM showcased on of their latest GPU, the Mali T-604, at SIGGRAPH 2012. There were 3 demos running in a tablet reference platform based on Samsung Exynos 5 Dual Cortex A15 processor clocked at 1.7 GHz: Timbuktu 2 showing improvement brought by OpenGL ES 3.0 such as higher details buffers, shadow comparison, etc… Hauntheim showcasing multiple lightings accelerated with GLES 3.0 and OpenCL (GPU compute) Enlighten, a demo where you can adjust the sun position and see the building shadows move smoothly in real-time.
Samsung showcased its new Exynos 5250 Dual-core Cortex A15 processor at Mobile World Congress as well as the corresponding Samsung Exynos 5 GAIA SMDK Development board. Announced in November 2011, the new Samsung Exynos 5250 processor features 2 Cortex A15 clocked at 1.7 GHz or 2 GHz, with a Mali-T604 GPU and support for dual-channel 800 MHz LPDDR3 RAM that allows for a data bandwidth of up to 12.8 GB/s. The processor is manufactured using 32-nm HKMG (High-K Metal Gate) technology that reduces leakage by 30% proving lower power consumption. Samsung claims the new Exynos 5 processors are twice as fast and consume twice as less power than its previous Exynos 4 application processor based on Cortex A9. This seems to confirm TI OMAP 5 vs. Nvidia Tegra 3 benchmark results. The Exynos 5250 supports embedded DisplayPort (eDP) interface up to WQXGA resolution (2560×1600), which is handy for Samsung since they are also working on a WQXGA 10.1″ LCD Panel […]
I’ve attended a webinar entitled “Harness the power and flexibility of the Midgard architecture for Embedded GPUs” presented Steve Steele, Product Manager at ARM Media Processing Division and sponsored by EETimes. Steve starts to talk about the current GPU architecture “Utgard” used in Mali-200, Mali-300 and Mali-400MP which allows resolutions up to 1080p and are used in many smartphones today including Samsung Galaxy S2 (Mali-400MP) which provides great graphics performance. He then explains how mobile devices are used today and what performance we may except in the future: Mobile As Main compute platform: New UI and Augmented Reality Social Networks and emails Content Creation/consumption 1 Device to multiple screen (e.g LCD screen and TV via HDMI) Evolving Processing Demand: Graphics Complexity multiplied by 25 Increase in screen size (1080p resolution support). Graphics API: Khronos OpenGL ES, Microsoft DirectX 11 Compute API: OpenCL, Renderscript Compute and Direct Compute. After this overview, he starts to talk about Midgard architecture and gives the […]
About one year ago, ARM announced the Mali-T604 GPU which has yet to be used in current products. Yet today, ARM announced an even more powerful GPU called Mali-T658 in Tokyo at Japan ARM Technical Symposium. Mali T658 is based on Midgard GPU architecture (as is Mali T604) which allows great GPGPU capabilities thanks to three types of pipeline (‘tri-pipe’) optimized repetitively for arithmetic, load/store and texturing. The GPU will also support standard graphics APIs such as Khronos OpenGL ES, OpenVG andMicrosoft DirectX® 11) as well as Compute APIs such as Khronos OpenCL (Full Profile), Google RenderScript compute and Microsoft DirectCompute. Performance-wise, Mali-T658 has twice as many shader cores and double the arithmetic pipelines per core which means the GPU can offer up to 10 times the performance of the Mali-400 MP GPU. On the compute side, Mali-T658 provides 4 times the processing power of Mali-T604. Mali-T658 will work with Cortex A7 and Cortex A15 processors either in standalone mode […]
Right before CES 2011, Freescale announced i.MX6 series, its latest multi-core Cortex A9 processor aimed at smartphones, tablets, eReaders and other consumer electronics equipment. Here’s an excerpt of the press release: Freescale delivers dramatic performance advances for tablet, smartphone, eReader, automotive infotainment and other hot consumer marketsCompatible i.MX 6 series scales from one to four cores and raises the bar with a new portfolio of high-performance, low-power multicore processors AUSTIN, Texas – Jan. 3, 2011 – Freescale Semiconductor introduces the i.MX 6 series of quad-, dual- and single-core applications processors designed to deliver outstanding performance and scalability to manufacturers targeting the hottest selling smart mobile, automotive infotainment and embedded device categories. Integrating one, two or four ARM® Cortex™-A9 cores running at up to 1.2 GHz each, the i.MX 6 series delivers up to five times the performance of Freescale’s current generation of applications processors. This performance provides additional headroom for unbounded user experiences in next-generation tablets, eReaders, smartphones, automotive infotainment […]
This year and next, many products will use processors based on ARM core cortex A8 and A9 tied-up with Mali 400 GPU. Those processors will run between 1 and 2 GHz. Earlier this month, ARM announced their new GPU Mali-T604 that will be used with Cortex A15 @ 1 to 2.5 GHz depending on the target application. The core design is ready, silicon foundries should be able to manufacture chips by the end of 2011 and products should be available for retail end of 2012 / beginning of 2013. ARM and their customer target the following applications for Cortex A15: Advanced Smartphones (1 to 1.5 GHz single or dual-core configurations) Mobile Computing (1 to 1.5 GHz single or dual-core configurations) High-end Digital Home Entertainment (1 to 2 GHz dual-core or quad-core configurations) Wireless Infrastructure (1.5 to 2.5 GHz quad-core, octo-core or larger configurations) Low-power Servers (1.5 to 2.5 GHz quad-core configurations) Here’s the block diagram of Cortex A15. For smartphones, […]
