Exynos, the line of System on a Chip (SoC) products from Samsung, were notably absent of ARM Mali GPUs. This, apparently, struck concern over how viable Mali will continue to be and whether ARM will continue to lose designs to competitors such as Imagination Technologies.
Then Samsung announced, Monday evening for us North Americans, the upcoming Exynos 5 Octa Processor will embed six ARM Mali-T628 GPU cores. The T628 GPU cores are capable of OpenCL 1.1 and OpenGL ES 3.0 standards which should allow applications to offload heavy batches of tasks, such as computational photography processing, with high efficiency and performance.
The Exynos 5 Octa contains four ARM Cortex-A15 cores at 1.8GHz, supported by four additional Cortex-A7 cores clocked at 1.3GHz. These processors are currently being sampled and should be produced in August.

Samsung's release of the 840 EVO earlier today likely prompted some questions, such as what type of flash does it employ and how does it achieve such high write speeds. Here is the short answer, with many slides in-between, starting off with the main differences between the 840 and the 840 EVO:
So, slightly increased specs to help boost drive performance, and an important tidbit in that the new SSD does in fact keep TLC flash. Now a closer look at the increased write specs:
Ok, the speeds are much quicker, even though the flash is still TLC and even on a smaller process. How does it pull off this trick? Tech that Samsung calls TurboWrite.
A segment of the TLC flash is accessed by the controller as if it were SLC flash. This section of flash can be accessed (especially written) much faster. Writes are initially dumped to this area and that data is later moved over to the TLC area. This happenes as it would in a normal write-back cache - either during idle states or once the cache becomes full, which is what would happen during a sustained maximum speed write operation that is larger than the cache capacity. Here is the net effect with the cache in use and also when the cache becomes full:
For most users, even the smallest cache capacity will be sufficient for the vast majority of typical use. Larger caches appear in larger capacities, further improving performance under periods of large write demand. Here's the full spread of cache sizes per capacity point:
So there you have it, Samsung's new TurboWrite technology in a nutshell. More to follow (along with a performance review coming in the next few days). Stay tuned!

Good morning from Seoul, Korea!
We're covering the 2013 Samsung Global SSD Summit, and the press embargo has just been lifted on a new SSD - the 840 EVO:
The EVO will push 10nm-class (1x nm) flash, promises increased (2x-3x) write speed improvements over the 840, and will be available in capaities as high as 1TB:
Full press blast after the break, and more to follow as the Samsung SSD Summit continues.

The Tech Report's resident Apple fan stepped away from his iPhone to try out the hottest Android phone, the Samsung Galaxy S4. He used them in parallel to be able to contrast their usability and while he loved the larger size of the S4 the TouchWiz was perhaps not his favourite part of the phone. As an Apple user he was a little surprised by the setup required to personalize the phone to his preferences, which is understandable when iOS is the only phone OS he had really spend time with. Take a peek at the article and maybe forward it on to a friend who would do well to read it.
"Last year, TR's Cyril Kowaliski bought an iPhone 5. For the past three weeks, however, he's been using one of the finest Android handsets on the market: the Samsung Galaxy S4. Here's what he has learned."

Earlier this week, set top box maker Boxee was acquired by Samsung in a deal worth approximately $30 million. The Korean company will retain all 45 Boxee employees as well as hold the rights to Boxee assets. Samsung plans to put the Boxee team to work on improving the user experience of its own Smart TVs. Unfortunately for Boxee users, the company announced on its website yesterday that it will be discontinuing its Cloud DVR service on July 10th.
Samsung's new "key talent and assets" from Boxee will work on improving the software used in Samsung's internet-connected Smart TVs. Smart TVs have become rather common, but much like the built-in 3D features, consumers may have a TV with Internet connected functionality but many do not utilize these features. The Boxee team will work on improving the interface, and hopefully with Sasmsung's muscle behind the team it will be able to offer enticing media functionality without running into rights issues with the big media companies, which Boxee has run into in the past.
Other than the brief announcement from Boxee and a couple of short quotes from Samsung to the BBC, details on the deal, the Boxee team's future involvement and road map on Boxee-inspired software are scarce. On one hand it is sad to see a small startup being bought out. On the other hand, it seems like it really takes a big company with lots of resources to make inroads into the living room, especially where TV and video is concerned due to media companies and cable companies (and in Comcast's case, both) fighting vigorously against these Internet streaming boxes. Hopefully Samsung realizes what it has and takes advantage of its new talent to make its Smart TVs better! In the meantime, there is always Roku to look to for alternative streaming boxes or XBMC and WMC for fully-fledged home theater PCs.
What do you think about the Boxee acquisition and the future of so-called "Smart TVs?"

Tagged: smartphone, sch-s738c, Samsung, just delivered, galaxy centura, android 4.0.4
Just Delivered is a new section of PC Perspective where we share some of the goodies that pass through our labs that may or may not see a review, but are pretty cool none the less.
Find the Galaxy Centura on Amazon!
I recently decided to move away from AT&T and try out a Straight Talk plan on the recommendation of friends. Moving to Straight Talk also meant getting a new phone though, because when I went to Straight Talk last month AT&T compatible SIM cards were still not available.
Long story short, I ended up getting the Samsung Galaxy Centura smart phone and Straight Talk's $45/month no-contract offering, which is around half of what I was paying AT&T! The phone itself cost $100.
The Samsung Galaxy Centura is smartphone that operates on Verizon's network and runs Android 4.0.4. Not the latest and greatest Android, but Samsung has not "blessed" the phone with its TouchWiz UI and a nice step up from the Samsung Infuse 4G's Android 2.3 OS that Samsung never bothered updating further (heh).
The Samsung Galaxy Centura is model number SCH-S738C (GP). It measures 4.44" (H) x 2.4" (W) x 0.45" (D) and weighs 4.4 ounces. The front of the phone features a 3.5" 262K TFT touchscreen with a resolution of 320 x 480. A small speaker grill and Tracfone logo sit at the top, while a Samsung logo and three capacitive buttons sit below the screen. The buttons are menu, home, and back. The front of the phone is black and surrounded by a glossy blue bezel that also matches the battery door.
The back of the phone has another Samsung logo, a speaker grill, and a 3MP camera capable of shooting 3MP stills and 640 x 480 video. The back of the phone comes off and doubles as the battery door. Samsung has put several clips along the edges to hold it in place, and may actually be a bit too secure as it can be hard to get the door off.
A standard 3.5mm headphone jack is located at the top of the phone, a power button is located on teh right side, and two volume buttons are located on the left edge. The bottom edge includes a micro-USB connector.
Internally, the Galaxy Centura features a Qualcomm MSM7625A SoC with a single core Snapdragon S1 processor (45nm, Cortex-A5) clocked at 800 Mhz, an Adreno 200 GPU, and a CDMA cellular radio. Additionally, the SoC is paired with 512MB of RAM, 4GB of internal storage (expandable by a microSD card under the battery door), and a decent 3.7V, 5.55 Wh, 1500 mAh battery. Other internal hardware includes an accelerometer, GPS, Bluetooth radio, and Wi-Fi radio. I am not as familiar with CDMA as GSM, but the Centura operates on Verizon's equivalent to AT&T's 3G network for data and vocie (though not at the same time). It is currently connected to Verizon's EVDO Rev. A:8 network. As far as network data speed, the fastest results I have been able to get, as measured by speedtest.net, are 1,276 kbps down and 487 kbps up.
While it had no problems running Android games at decent frame rates, 3DMark mobile pushed it to its limits. It scored 536 in the Ice Storm benchmark and 281 in the Ice Storm Extreme benchmark, for example. Unfortunately, this 3DMark app was not available when I had the Infuse 4G so I am not able to offer up comparison results.
Now that the specifications and pricing is out of the way, I can talk a bit about first impressions. I have been using the smartphone for a couple of weeks now, and it is a fairly solid device, especially considering the price of the hardware (and the monthly plan is cheap too). It is noticeably slower at some tasks than my old Samsung Infuse, but that is to be expected with slower-clocked hardware. With that said, performance was actually much better than I expected it to be. The phone is able to run apps and games without issue, though when multi-tasking the game frame-rate starts to dip. Switching between applications (especially with a game running) is not as snappy as with my Infuse, but not terribly slow either. I'm not sure if it's the newer version of Android or not, but the software side of things seems to work well on this hardware.
The physical smartphone is plastic, but it feels well built. Admittedly, I have dropped my new phone quite a few more times than I would have liked (heh), but it has held up really well. It has not yet gone plastic to concrete yet though. Dropping it on tile and carpet has not caused any issues, however. When holding the phone and using the touchscreen, there is no creaking of the battery door and it seems to stand up to pressure without problems. With that said, I do have one complaint about the physical hardware, and that is that when holding the phone in the landscape position, the end of the back cover next to the speaker grill gives too much and makes a creaking noise when pressed in (say, when playing a racing game). That is the only area that exhibits that issue, however. It is likely due to the fact that Samsung carved out a bit internally for the microSD card and speaker underneath the back cover on the phone itself whereas the rest of the phone's back cover fits snugly to the back of the phone.
Overall, I'm happy with the phone, it gets excellent signal where I live now and is a good Android (albeit 4.0.4) experience for only $100 for the hardware. If you are off contract right now and thinking about switching to one of the many MVNOs (and live in an area with good Verizon coverage), I'd recommend trying out the Samsung Galaxy Centura from what I've experienced thus far. It is not the latest or fastest hardware by far, but it has great price/performance.

Late last week, Samsung announced new hardware at an event in London. Among the products shown off, Samsung unveiled the 10.1" ATIV Tab 3 and the 13.3" ATIV Q Convertible notebook. Both machines are x86-64 and run the full version of Windows 8.
Samsung ATIV Q
The ATIV Q is the premium device, with Intel's latest Haswell processor, a high resolution display on a unique sliding hinge design, and a thin ultra-portable form factor. The 13" convertible notebook is 14mm thick and weighs about 2.8 pounds. The system features an impressive 13" touchscreen display with a resolution of 3200 x 1800 (275 PPI) and 178-degree viewing angles.
The ATIV Q has a unique sliding hinge design that allows the display to lay flat in slate tablet mode, held above the keyboard parallel to the keyboard, and in laptop mode with the display snapped to the top of the keyboard and at an angle. The display further supports the company's S-Pen stylus. In order to maintain the 14mm thick figure, Samsung has packed the processor and some of the other internals into the display hinge rather than the traditional placement in the laptop's base (under the keyboard). The hinge also hosts USB 3.0 and mini-HDMI ports. Here's hoping the build quality is good and the hinge is sturdy as having the internals packed into the hinge is a risky proposition.
Other IO (located around the laptop's base) includes USB, power, and Ethernet jacks. Note that the ATIV Q does not have a touch pad. Users will need to use the eraser point or the touchscreen to navigate.
Internally, the ATIV Q features an Intel Core i5 CPU with HD 4400 graphics, 4GB of RAM, a 128GB SSD, and a battery that is reportedly capable of delivery 9 hours of normal usage. The integrated HD 4400 graphics will not get you much, but it is just barely enough to run older games at around 30 FPS at 1280 x 1024 and reduced quality settings according to reviews of systems with similar specs around the net.
On the software side of things, the ATIV Q runs the full version of Microsoft's Windows 8 operating system. Samsung is also bundling the PC with a virtualized installation of Android 4.2.2 that runs on top of -- and can share files with -- Windows 8. Users can access and run traditional Windows applications, Windows 8 (Metro/Modern UI/Whatever It is Called This Week) apps, and applications from the Google Play store. The WIndows 8 and Android OSes further share folders such that files can be shared between them. Application shortcuts for the Android apps can also reportedly be linked to from the Windows 8 Start Screen.
ATIV Tab 3
The ATIV Tab 3 was also announced at the Samsung event in London. This device is a 10.1" tablet measuring 8.2mm thick and weighing 550g (approximately 1.21 lbs). It is powered by an Intel Atom Z2760 SoC, 2GB of RAM, and 64GB of internal storage. The 10.1" display has a resolution of 1366 x 768. Samsung is reportedly including a battery rated at 10 hours of usage. The system supports microSD cards for expansion, which is good because there is not going to be much storage space left for user-space files after the OS and bundled programs.
The ATIV Tab 3 comes with the full version of Windows 8 and the full version of Microsoft Office 2013.
Pricing and availability for the two new ATIV tablets has not yet been announced. The Q is a tablet to watch out of for though. So long as the build quality is there, I think it will be popular with those fans of convertible notebooks (of which I am one).

As Scott covered earlier this week, Apple quietly announced an update to the MacBook Air line along side the headline-grabbing Mac Pro redesign preview. Being a MacBook Air user for the past 2 years, I decided it was time to replace my Sandy Bridge-based model with some new Haswell goodness. Today marked the first day of retail store availability, and I picked up an 11" model with 256GB SSD.
Naturally, when I got back to the office there was only one route to take, installing Windows and disassembling it. While Anand uncovered the fact that these MacBooks were hiding a new unadvertised option, in a PCI-Express based SSD, I wanted to check it out for myself.
When I did some digging, I discovered that while Anand found a Samsung based SSD in his MacBook, mine actually contained a model by Sandisk. I did a quick initial benchmark in OS X, and proceeded to inspect the hardware itself.

Tagged: Intel, atom, Clover Trail+, SoC, Samsung, Galaxy Tab 3 10.1
While Reuters is being a bit cagey with their source, if true: Intel may have nabbed just about the highest profile Android tablet design win possible. The, still currently unannounced, Samsung Galaxy Tab 3 10.1 is expected to embed Intel's Clover Trail+ System on a Chip (SoC). Samsung would not be the largest contract available in the tablet market, their previous tablets ship millions of units each; they are a good OEM vendor to have.
Source: BGR India
Samsung is also known for releasing multiple versions of the same device for various regions and partners. The Galaxy Tab 10.1 and Galaxy Tab 2 10.1 did not have a variety of models with differing CPUs like, for instance, the Galaxy S4 phone did; the original "10.1" contained an NVIDIA Tegra 2 and the later "2 10.1" embed a TI OMAP 4430 SoC. It is entirely possible that Intel won every Galaxy Tab 3 10.1 tablet ever, but it is also entirely possible that they did not.
Boy Genius Report India (BGR India, video above) also claims more specific hardware based on a pair of listings at GLBenchmark. The product is registered under the name Santos10: GT-P5200 being the 3G version, and GT-P5210 being the Wi-Fi version.
These specifications are:
- Intel Atom Z2560 800-933 MHz dual-core SoC (4 threads, 1600 MHz Turbo)
- PowerVR SGX 544MP GPU (OpenGL ES 2.0)
- 1280x800 display
- Android 4.2.2
I am not entirely sure what Intel has to offer with Clover Trail+ besides, I would guess, reliable fabrication. Raw graphics performance is still about half of Apple's A6X GPU although, if the leaked resolution is true, it has substantially less pixels to push without being attached to an external display.
Maybe Intel made it too cheap to refuse?
