Samsung is the only company with both logic and memory process, quite scary, actually. Not to mention consumer products. One-stop shop with government support is too much momentum for rest of the world.

HOw come samsung is so late with quad core? IIRC NVidias quad core Tegra 3 is already shipping on some tablets.

The 45nm dual core A9 Exynos 4210 uses Mali-400MP4. The previous generation chip used PowerVr540 (chip that was recently renamed Exynos 3110). Given that Samsung last year licensed multi-core PowerVr series 5, and apparently has "access to" Mali T604 and Mali T658, it seems at odds they would rework their own inhouse graphics that were last seen in single core A8,S5PC100. I still suspect the presenter chose his words poorly.

The presenter said it was Samsung's own GPU block design, an upgrade of one used in its 45 nm chips.

"Samsung is using the latest version of its own graphics unit for the chip." Did you mean they are using Arm's own graphics unit? Given the description is 4 pixel processors and 1 vertex processor, it sounds very much like the Mali400MP4 as used in the Exynos 4210/4212.

If as mentioned it is based on A9 then it sould still be for the upper end mobile handset rather than tablet. The power saving achieved is quite good but the comparison is only over its earlier devices and Samsung handhelds are not known for long battery times.

Yes, I suspect it could be used in either smartphones or tablets. The focus here is advanced features and umph, though, so don't expect this chip to drive major cost reductions.

Will Samsung employ this in Tablet or for Mobile phone? It will be good if it brings down the cost of devices.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
