A few months back, Samsung debuted its latest Exynos 4 quad core mobile System on a Chip (SoC) based on four Cortex A9 cores. The company recently released details of its next generation Exynos processor, only this time it is a dual core variant. The Samsung Exynos 5 Dual (Exynos 5250) is packing the latest mobile ARM technology with two ARM Cortex A15 CPU cores and a Mali T604 graphics core.
The dual core processor is running at 1.7 GHz and features the NEON fixed function hardware for accelerated video decoding. Further, the Mali T604 GPU is based on ARM’s new Midgard architecture. The T604 includes a unified shader design with support for OpenGL ES 3.0 and the full OpenCL 1.1 profile. Not too shabby for a mobile GPU!
The Exynos 5250 also sees an upgrade (from 6.4 GB/s in the Exynos 4) in memory bandwidth to 12.8 GB/s between the processor and two port LPDDR3 memory at up to 800Mhz. The increased memory bandwidth along with the new–and more powerful–processor and graphics hardware enables Samsung to offer support for much higher resolution displays up to WXQGA or 2560x1600 pixels.
Other features of the new Exynos 5 dual core processor include USB 3.0 support, wireless display support, and a claimed ability to playback 1080p video at 60 FPS using Google’s VP8 video decoder (no word on H.264 performance, though the ARM processor’s NEON hardware should handle those videos well enough). The GPU is also able to allegedly use 20-times less power when displaying a static image (such as a web page or ebook page) called PSR mode.
According to the Android Authority, the first product to be powered by the new Samsung Exynos 5 processor will likely be the company’s upcoming Galaxy Tab 11.6 tablet. Quad core variants of the Exynos 5 should come out following the successful dual core launch.
The Cortex A15-based mobile processor is packing some impressive specifications, and it will be interesting to see Exynos 5-powered devices. Specifically, it will be interesting to see how it stacks up compared to products like NVIDIA’s Tegra 3, TI’s OMAP 5, and even Samsung’s own Exynos 4 quad core SoC. Are you excited about the new dual core SoC?

If you are an Android developer and have been itching to get your hands on some high end, quad core hardware, than Korean company HardKernel may have just what you’re looking for. The new ODROID-X is an Android developer board (meaning it comes as just a single board computer sans case or accessories. For $129 plus shipping and customs fees, you can have a 90 x 94mm PCB with a Samsung Exynos 4412 ARM Cortex-A9 quad core at 1.4 GHz (1MB cache), Mali 400 GPU, 1GB RAM, and runs on a 5V, 2A power adapter.
IO for the ODROID-X includes headphone and microphone jacks, six USB 2.0 ports, 10/100 Ethernet, SDHC card slot, 50-pin GPIO connector, UART serial connector, MIPI-CAM camera connector, HDMI, and a power jack. In other words, it is extremely expandable. It is capable of outputting 1080p video over HDMI when using the H.264 video codec thanks to dedicated hardware acceleration. Hardkernel will happily sell you accessories but you would likely be better off buying it from a local retailer or online shop that is in-country to avoid the extra shipping and customs fees. The power jack and other ports are standard, so there aren’t any worries there. Android 4.0 ICS is reportedly available for download, though no word yet on when the newly announced Android 4.1 "Jelly Bean" OS build will be up on the site.
Thanks to the Samsung Exynos 4, you definitely have more oomph than the 700 MHz ARMv7 in the Raspberry Pi, though this board isn’t nearly as small (and costs about four times as much). If you need the extra horsepower, this may be worth considering at this price but be sure figure out the import taxes and shipping for your location to figure out what it will really cost you to get your hands on. Read more about the ODROID-X's specifications over at the Hardkernel website.

Tagged: TSMC, Samsung, amd, nvidia, 28nm, rumour
All of the speculation about the problems TSMC has had with their 28nm process and the possible issues they might have producing enough wafers to meet their clients demands. Today we hear from DigiTimes that Qualcomm is going to switch to Samsung, possibly because TSMC was focusing on AMD and NVIDIA, but this is pure speculation at the moment. What seems more reliable is that GPU vendors are stating that both AMD and NVIDIA are sticking with TSMC which makes a lot of sense, even if TSMC has problems delivering it is a better alternative than AMD or NVIDIA redesigning their graphics processors to be compatible with Samsung's process. The story also mentions that in 2013 Brazos 2.0 and Hondo will be moved to a 28nm design, again likely sourced at TSMC.
"While Qualcomm has reportedly switched foundry orders for its 28nm-based Snapdragon S4 processors from Taiwan Semiconductor Manufacturing Company (TSMC) to Samsung Electronics because TSMC's 28nm capacity has failed to meet its needs, Nvidia and AMD may not follow suit, according to graphics card makers.
TSMC has the upper hand over Samsung in 28nm technology, yield rate and price and therefore changing foundry partnership involves high risks, the sources said. In addition, Nvidia is expected to consider Samsung's ARM-based processors in competition with its Tegra 3 processors, the sources indicated."

Introduction, Design, User Interface
In August of 2011 I reviewed the Acer AC700-1099, one of two Chromebooks available in the North American market. The review was almost entirely negative. The hardware wasn’t great and the operating system was a bit of a mess–capable of only the most basic tasks.
Since then, the small surge of hype that surrounded the Chrome OS release has receded. You could be mistaken for thinking Google has abandoned it, but they haven’t. In typical Google fashion it has been slowly, quietly improved. Performance tweaks have allegedly improved web browsing, a proper file manager has been added and Google has just launched Google Drive, its cloud storage service.
Such enhancements could address a lot of the concerns I had with the Acer rendition. Do they? That’s what we’re here to find out. Let’s start with the basics - what’s inside?
The hardware inside the Samsung Series 5 is nearly identical to what was inside the Acer AC700-1099 that we reviewed late last year. We’re talking an Atom processor that must rely on its own IGP, two gigabytes of RAM and a tiny–but quick–16GB solid state drive.
While the equipment is the same, the pricing has changed. When we reviewed the Acer Chromebook it was $349.99. That has been slashed to $279.99. The Series 5, which used to be priced at $429, is now sold for just $299.

Previous rumors of a quad core smartphone from Samsung proved to be true at the 2012 Samsung Unpacked event in London on Thursday. There, they officially unveiled the Samsung Galaxy S III Android 4.0 smartphone.
The new smartphone runs the latest Android 4.0 “Ice Cream Sandwich” mobile operating system with an updated version of Samsung’s TouchWiz interface that adds additional functionality on top of the vanilla Android experience. Many sites have mentioned that Samsung really focused in on the software and experience aspects of the phone rather than the underlying hardware specifications and performance characteristics.
The company is introducing a number of new features with the Galaxy S III including voice control with S Voice, “S Beam” wireless file transfer, and a feature called “Pop up Play” that allows users to play videos while checking email and browsing the web. The S Voice feature lets users turn their phone on by saying “Hi, Galaxy” as well as writing emails, sending text messages, hitting “snooze” on the alarm, organizing schedules, and taking photos. Another feature that the Galaxy S III offers is NFC payment.
On the hardware side of things, the smartphone measures 136.6 x 70.6 x 8.6 mm, and weighs 133g. On the outside, there is a 4.8 inch HD Super AMOLED Pentile display with a resolution of 1280x720. There is a 1.9 megapixel camera on the front and a 8 megapixel camera on the back with backside illumination to improve low light performance. The phone is available in Pebble Blue and Marble White at launch, with additional color options to follow. Powering the software and HD display is a 2,100 mAh battery, 16, 32, or 64 (coming soon) Gigabytes of storage, microSD card slot, 1GB of RAM, and a Exynos 4 quad core processor. It also features 802.11 a/b/g/n WiFi (support channel bonding), GPS, GLONASS (radio navigation system), NFC, and Bluetooth 4. As far as cellular technology, it supports EDGE, 3G, and 4G (depending on which model you buy–more on that below).
Matt at Engadget managed to shoot some video of the new Samsung phone at the launch event, seen below.
While some models will run the Exynos 4 quad core processor, the US version will likely have a dual core Qualcomm processor due to incompatibilities between the necessary LTE radio and the Exynos 4 SoC. In the end, the general user experience should not suffer as a result but it is still regrettable that there is not a quad core part from a hardware perspective. Because the Exynos 4 SoC is based on older ARMv7 CPU cores and a Mali 400 GPU core, it will be faster in multithreaded tasks but the newer dual core Qualcomm in the LTE models will be faster in general usage thanks to the newer CPU technology and Android’s notoriously poor multithreaded performance. Users should not write off the dual core Galaxy S III phones on specifications alone.
The phone will be available for purchase in Europe at the end of May, with other countries to follow. No official word on pricing has been given yet.
Are you still excited for the US Galaxy S III now that it is official? Will you be upgrading or waiting on one of the other upcoming Android smatphones?

Samsung has an event scheduled for May 3rd called Mobile Unpacked where it will be unveiling their latest Galaxy series smartphone. It seems as if the company was too excited about the new hardware to wait because they have teased small bits of information on the processor. The new chip has been named the Exynos 4 and is a quad core processor running at 1.4 GHz.
Based on a 32nm HKMG (High-K Metal Gate) process node, Samsung claims the SoC uses 20% less power than it’s 45nm predecessors. The quad core processor is more power efficient thanks to the lower process node and the ability of the chip to turn individual cores off when not in use. As far as performance, the company claims the new quad core part is twice as fast as the older dual core 45nm chips. The Exynos 4 also has an integrated image signal processor for high quality camera processing and support for multi format codec (MFC) decoding. The MFC engine allows the chip to process a variety of 1080p HD video files.
A few things that are noticeably absent from the Samsung product page include any specific performance numbers, architecture details, and benchmarks. Samsung is keeping a tight lid on that information until the release but once reviewers get their hands on the Galaxy III independent benchmarks are soon to follow. The comparison between the Exynos 4 and NVIDIA’s Tegra 3 should be interesting.

Apple is getting some help in its legal quest to force Samsung out of the mobile phone business, even though Samsung is one of their major suppliers. Both Intel and Qualcomm's legal teams have sifted through Samsung's source code and are offering more potential infringements for Apple to use in their case. Qualcomm helped develop the 3G standard and so possess quite a bit of intellectual property that pertains to the use of 3G, while Intel owns an immense amount of telecom and chip patents which Samsung may have infringed upon. The Register speculates on just why Qualcomm and Intel would offer their legal teams to Apple, as well as pointing out the obvious irony of Apple attacking its memory and screen manufacturer.
"CHIP VENDORS Intel and Qualcomm have agreed to help Apple in a lawsuit against Samsung by providing source code, according to one of Apple's lawyers.
Apple's seemingly never ending battle with Samsung over smartphone patents will get helping hands from Intel and Qualcomm as the firms hand over source code to support Apple's case. According to Andrew Fox, Apple's lawyer, Intel's and Qualcomm's legal teams have sifted through the source code and agreed to provide it to Apple."

Introduction, Specifications, and Packaging
Samsung has been in the SSD business for a good long while now. My first "serious" SSD setup consisted of a pair of 32GB G.Skill 'FlashSSD's in a RAID. A few months later I upgraded to an Intel X25-M, starting working for PCPer, and have since seen a slew of different controller types come and go. Of those, Samsung and Intel both come to mind as the most reliable controllers out there. Of those two, Samsung has always been the primary choice of PC OEMs. It may have been because the Samsung controllers have always leaned towards the slow-but-steady approach. Other fire breathing controllers would be quick out of the gate but slow over time as fragmentation effects set in, while Samsung controllers would take the hit on random IOPS, but they maintained that lower level even after repeated and sustained abuse. They were not the fastest, but as a testament to their consistency, I continue to use one of the two aforementioned G.Skill drives in the PCPer Storage Testbed to this day.

The Samsung Galaxy Note is probably the biggest cellphone since the ill fated N-Gage, though instead of being a portable gaming system that thinks it is a phone you have a phone which thinks it is a tablet. Dual purpose devices have a somewhat flaky reputation but some combination tools end up being more useful than their separate component pieces. With an ARM cortex A9 powering a 5.29" 800 x 1280 AMOLED screen this Android device seems to have a lot of promise. Read the full review at Hardware Look to see how well Samsung combined the two devices into one.
"The Samsung Galaxy Note is a smartphone that has gone in the opposite direction of the conventional modern technology. As we see technology advancing, we see it getting smaller and smaller, the Samsung Galaxy Note is the largest smartphone on the market, posing a huge 5.29-inch display..."
