It was only last week that new details of the Exynos 5 dual-core arrived in the form of a slide, detailing GPU performance of 2.1 GPixels/s. This time, however, the details listed are from an official document.

Confirming previous details, the SoC will feature 12.8GB/s of bandwidth through two 32-bit 800MHz memory ports, capable of supporting LPDDR3 and standard DDR3. On-chip support for USB 3.0 and SATA 3.0 has also been introduced. Another point of note is the inclusion of HSIC and C2C interfaces, capable of communicating with LTE modems.

Support for the MMC 4.5 standard is present, which offers embedded MMC speeds of 200MB/s, with the four channels also suggesting support for the SD UHS-II standard.

The 4-lane MIPI connection suggests support for incredibly high resolution image sensors, this is backed-up by details revealing that the chip's image processor is capable of handling a full 8-megapixels at 30fps.

For one final juicy bit of information, the chip, which features an ARM Mali-T604 GPU and a dual-core ARM Cortex-A15 CPU will be clocked at either 1.7GHz or 2.0GHz, with performance at the latter speed churning out 14,000 DMIPS, which is 0.2 DMIPS/MHz per core greater than Qualcomm's new Snapdragon S4 CPU and, 1.0 DMIPS/MHz per core greater than NVIDIA's Tegra 3.

In layman's terms, we should be seeing CPU performance matching the Tegra 3 quad-core, though in practise, the Exynos 5 should surpass the Tegra 3 as many mobile applications perform at their best in a dual-core scenario, where the Exynos's fast, 2GHz speed, will come into play.

Before we get another "ARM is teh l33t, gonna killz Intel and we all be ARM on desktop by next week" comment lets just put 14,000 DMIPS in context, that's roughly equivalent to a 2005 Athlon 64 X2 (http://en.wikipedia.org/wiki/Instructions_per_second). [en.wikipedia.org]

Very nice to have that CPU power in such a low TDP, but that's rather to be expected 7-8 years later. ARM architecture lends itself very nicely to phones & tablets, but where we aren't TDP constrained it has a LONG way to go.

Oh DMIPS what a silly measure anyway. Anyone run something like GeekBench on one yet? IIRC the new Tegra3 scores ~1500 whereas an i7 2600K scores an order of magnitude higher.
But its a UK company, let them win... its about time we got some companies doing well in the UK, it seems as a whole the government doesnt care about the semiconductor industry and screws us over whereas places like china get millions pumped into research when asked!. Although that could do with the fact gov dont care unless its in london...

Back on track, useful and arm plays to the strength of low tdp designs so keep it up :D

Bare in mind that this is dual-core at 32nm, ARM claims the NEON/FPU vector processing performance has been improved over the A9 so we should see some nice FLOPS figures.

What should be interesting when comparing against something like an i7 however, is that this SoC also features an ARM Mali-T604 which has support for standardised OpenCL 1.1 and DirectX 11, meaning that there's potentially a lot of floating point power that's fairly easy to tap, from the on-die GPU.

If we're talking about scaling up then what interests me a lot is the AMBA® 4 Cache Coherent Interconnect present with the A15, which can potentially allow efficient linking of over 100 cores, I'd be very interested to see how the end product stacks up.
When they put this chip in a mobile - im buying it. PLEASE samsung use it in the GS3!!!
