Along with Al's review of the new EVO line you can get a second opinion from The Tech Report about the performance of the new SSD with a fast cache. The majority of the storage is 19nm TLC NAND but there is an SLC cache sitting between the controller and that long term TLC storage to help with the overall responsiveness of the drive, aka TurboWrite. In the 120 and 250GB models that cache is 3GB while in the larger models you get a 6GB cache. In their real world testing the new EVO drive is incredible at large file copying though Sandforce drives can beat it in small file copy speeds, likely thanks to the compressed write trickery that controller family is so good at. Check out the review here and keep your fingers crossed that MSRP is the acual price these drives sell at.
"Samsung's entry-level 840 EVO SSD combines affordable TLC NAND with a server-style SLC cache. We explain the drive's unique buffering tech and explore how it affects performance."

Introduction and Specifications
Last week, Samsung flew a select group of press out to Seoul, Korea. The event was the 2013 Samsung Global SSD Summit. Here we saw the launch of a new consumer SSD, the 840 EVO:
This new SSD aims to replace the older 840 (non-Pro) model with one that is considerably more competitive. Let's just right into the specs:
NVIDIA Finally Gets Serious with Tegra
Tegra has had an interesting run of things. The original Tegra 1 was utilized only by Microsoft with Zune. Tegra 2 had a better adoption, but did not produce the design wins to propel NVIDIA to a leadership position in cell phones and tablets. Tegra 3 found a spot in Microsoft’s Surface, but that has turned out to be a far more bitter experience than expected. Tegra 4 so far has been integrated into a handful of products and is being featured in NVIDIA’s upcoming Shield product. It also hit some production snags that made it later to market than expected.
I think the primary issue with the first three generations of products is pretty simple. There was a distinct lack of differentiation from the other ARM based products around. Yes, NVIDIA brought their graphics prowess to the market, but never in a form that distanced itself adequately from the competition. Tegra 2 boasted GeForce based graphics, but we did not find out until later that it was comprised of basically four pixel shaders and four vertex shaders that had more in common with the GeForce 7800/7900 series than it did with any of the modern unified architectures of the time. Tegra 3 boasted a big graphical boost, but it was in the form of doubling the pixel shader units and leaving the vertex units alone.
While NVIDIA had very strong developer relations and a leg up on the competition in terms of software support, it was never enough to propel Tegra beyond a handful of devices. NVIDIA is trying to rectify that with Tegra 4 and the 72 shader units that it contains (still divided between pixel and vertex units). Tegra 4 is not perfect in that it is late to market and the GPU is not OpenGL ES 3.0 compliant. ARM, Imagination Technologies, and Qualcomm are offering new graphics processing units that are not only OpenGL ES 3.0 compliant, but also offer OpenCL 1.1 support. Tegra 4 does not support OpenCL. In fact, it does not support NVIDIA’s in-house CUDA. Ouch.
Jumping into a new market is not an easy thing, and invariably mistakes will be made. NVIDIA worked hard to make a solid foundation with their products, and certainly they had to learn to walk before they could run. Unfortunately, running effectively entails having design wins due to outstanding features, performance, and power consumption. NVIDIA was really only average in all of those areas. NVIDIA is hoping to change that. Their first salvo into offering a product that offers features and support that is a step above the competition is what we are talking about today.

Tagged: Samsung, mali, exynos
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.

Tagged: Samsung, galaxy s4
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?"
