ARM Holdings Stories November 30, 2011

Samsung is readying an improved version of the Exynos dual-core chip that will enable next year’s smartphones and tablets to pack in 3D stereoscopic displays with ultra-high resolutions, in addition to the faster graphics and speedier CPU performance. The new chip will be called the Exynos 5250, V3.co.uk reports, and will utilize the Cortex A15 architecture from fables semiconductor design firm ARM Holdings.

It should clock in 14,000 DMIPS, Samsung said, twice the number of instructions compared to the typical ARM Cortex A9-based mobile chips such as Apple’s A5 silicon powering iPad 2 and iPhone 4S or Samsung’s own commonly used dual-core 1.4GHz Exynos 4210 silicon. Samsung did not say what graphics core the 5250 uses beyond mentioning a quadruple jump in graphics performance over the Exynos 4210. The 4210 uses the pretty darn fast Mali-400 GPU from ARM sporting four cores.

Note that Samsung two months ago announced a revised version of the Exynos 4210 chip, dubbed the Exynos 4212. It sports a 1.5GHz clock speed and a dual-core Cortex A9 processing core from ARM, among other things. The Exynos 5250 should make its way into Samsung’s high-end smartphones and tablets in the second quarter of 2012, when the 5250 is expected to go into mass production.

Four times faster graphics processing will let the new Exynos 5250 chip drive tablet displays with WQXGA resolutions of up to 2,560-by-1,600 pixels. Apple too is rumored to upgrade its market-leading iPad with a QXXGA display early next year with. Production of the Retina Display for iPad 3 has already started, the rumor has it. The Cupertino, California company is said to source panels from Samsung Electronic, LG Display and Sharp.

ARM Holdings Stories November 21, 2011

Samsung is thought to be at work developing a quad-core chip to power the Galaxy S III, an addition to the Galaxy smartphone family expected to be unveiled at Mobile World Congress which runs February 27-March 1 in Barcelona, Spain. According to PocketNow, based on the source code at kernel.org, the new chip will be marketed as the Exynos 4412 and will feature four processing cores.

Samsung recently launched the 32-nanomenter Exynos 4212 chip with a dual-core ARM Cortex-A9 processing core clocked at 1.5GHz and ARM’s quad-core Mali-400 GPU. Like Apple’s upcoming A6 chip (said to be manufactured by Samsung) and Nvidia’s Tegra 3 silicon, the rumored Exynos 4412 chip should take advantage of the four cores of the Cortex-A9 processor from ARM Holdings. Its closes competitor, however, will be a 2.5GHz Qualcomm Snapdragon quad-core beast allegedly debuting early next year in the HTC Zeta smartphone.

Unlike the Tegra 3 chip which employs Nvidia’s own GeForce graphics processor or Apple’s A6 that is likely to tap Imagination Technologies’ next-generation PowerVR GPU, the Exynos 4412 could use the recently introduced Mali-T658 graphics unit which delivers up to ten times the graphics performance of the Mali-400 GPU and four times the GPU compute performance of the Mali-T604 GPU.
