Grand Theft Auto: San Andreas for iOS hits iPhone, iPad, and iPod touch
Grand Theft Auto: San Andreas for iOS hits iPhone, iPad, and iPod touch
Grand Theft Auto: San Andreas for iOS has hit the App Store, bringing the latest open-world gaming experience to the iPad, iPhone, and iPod touch. The game, which brings three cities and a promised 70+ hours of gameplay to iOS devices, is a $6.99 download and features remastered graphics and new character models, while some of the more recent, more powerful Apple hardware get extra visual gloss.
The game runs on the iPhone 4S, iPhone 5, iPhone 5s, iPhone 5c, iPod touch 5th-gen, iPad 2, 3rd-gen, and 4th-gen, iPad Air, iPad mini, and iPad mini with Retina display. However, those with an iPhone 5/5s/5c, or an iPad 4th-gen or more recent, will get dynamic detailed shadows and real-time environmental reflections, taking advantage of the more capable graphics chips inside.
Controls have been reworked to suit a touchscreen interface, with dual virtual analog sticks to navigate movement and camera. However, there are three different control schemes to choose between, and they can be customized.
Alternatively, GTA: San Andreas for iOS also works with Made-for-iOS controllers, such as thePowerShell gamepad Logitech launched recently, for those who demand physical controls.
The game also features a new checkpoint system, and a cloud save system which allows Rockstar Social Club Members to sign into their account and pick up play no matter which iOS device they’re using. So, you can play during your commute and then pick up where you left off on your iPad when you get home.
Meanwhile, Rockstar Games is still prepping versions for Android, Amazon’s Kindle Fire tablets, and Windows Phone smartphones. They’re “coming soon” the studio says; last month, it was estimated that all versions would be out sometime in December 2013.

Samsung SSD 840 EVO Review: 120GB, 250GB, 500GB, 750GB & 1TB Models Tested
I'm continually amazed by Samsung's rise to power in the SSD space. If you compare their market dominating products today to what we were reviewing from Samsung just a few years ago you'd assume they came from a different company. The past three generations of Samsung consumer SSDs have been good, but if you focus exclusively on the past two generations (830/840) they've been really good.
Last year Samsung bifurcated its consumer SSD lineup by intoducing the 840 Pro in addition to the vanilla 840. We'd seen other companies explore a similar strategy, but usually by playing with synchronous vs asynchronous NAND or sometimes just using different NAND suppliers between lines. Samsung used NAND to differentiate the two but went even more extreme. The non-Pro version of the 840 was the first large scale consumer SSD made with 3-bit-per-cell MLC NAND, more commonly known as TLC (triple-level-cell) NAND. Companies had toyed with the idea of going TLC well before the 840's release but were usually stopped either by economic or endurance realities. The 840 changed all of that. Although it didn't come with tremendous cost savings initially, over time the Samsung SSD 840 proved to be one of the better values on the market - you'd just have to get over the worry of wearing out TLC NAND.
Despite having a far more limited lifespan compared to its 2bpc MLC brethren, the TLC NAND Samsung used in its 840 turned out to be quite reliable. Even our own aggressive estimates pegged typical client write endurance on the 840 at more than 11 years for the 128GB model.
Samsung 19nm TLC NAND
We haven't seen Samsung's love of TLC embraced by other manufacturers. The most significant contrast actually comes from Micron, another NAND supplier turned SSD manufacturer, and its M500. Relying on 2bpc MLC NAND, the M500 gets its cost down by using a combination of large page/block sizes (to reduce overall die area) as well as aggressively embracing the latest NAND manufacturing processes (in this case 20nm). That's always been the Intel/Micron way - spend all of your time getting to the next process node quickly, and drive down cost that way rather than going TLC. The benefit of the TLC approach is the potential for even more cost reduction, but the downside is it usually takes a while to get production to yield high enough endurance TLC to make it viable for use in SSDs. The question of which is quicker is pretty simple to answer. If we look at the 25nm and 20nm generations from IMFT, the manufacturer was able to get down to new process nodes quicker than Samsung could ship TLC in volume.
The discussion then shifts to whether or not TLC makes sense at that point, or if you'd be better off just transitioning to the next process node on MLC. Samsung clearly believes its mainstream TLC/high-end MLC split makes a lot of sense, and seeing how the 840 turned out last time I tend to agree. It's not the only solution, but given how supply constrained everyone is on the latest NAND processes this generation - any good solution to get more die per wafer is going to be well received. Samsung doesn't disclose die areas of its NAND, so we unfortunately can't tell just how much more area efficient its TLC approach is compared to IMFT's 128Gb/16K page area efficient 20nm MLC NAND.
As with any other business in the tech industry, it turns out that a regular, predictable release cadence is a great way to build marketshare. Here we are, around 9 months after the release of the Samsung SSD 840 and we have its first successor: the 840 EVO.
As its name implies, Samsung's SSD 840 EVO is an evolution over last year's SSD 840. The EVO still uses 3-bit-per-cell TLC NAND, but it moves to a smaller process geometry. Samsung calls its latest NAND process 10nm-class or 1x-nm, which can refer to feature sizes anywhere from 10nm to 19nm but we've also heard it referred to as 19nm TLC. The new 19nm TLC is available in capacities of up to 128Gbit per die, like IMFT's latest 20nm MLC process. Unlike IMFT's 128Gb offering, Samsung remains on a 8KB page size even with this latest generation of NAND. The number of pages per block is also more like IMFT's previous 64Gbit 20nm MLC at 256:
IMFT vs. Samsung NAND Comparison IMFT 20nm MLC IMFT 20nm MLC Samsung 19nm TLC Samsung 21nm TLC Samsung 21nm MLC Bits per Cell 2 2 3 3 2 Single Die Max Capacity 64Gbit 128Gbit 128Gbit 128Gbit 64Gbit Page Size 8KB 16KB 8KB 8KB 8KB Pages per Block 256 512 256 192 128 Read Page (max) 100 µs 115 µs ? ? ? Program Page (typical) 1300 µs 1600 µs ? ? ? Erase Block (typical) 3 ms 3.8 ms ? ? ? Die Size 118mm2 202mm2 ? ? ? Gbit per mm2 0.542 0.634 ? ? ? Rated Program/Erase Cycles 3000 3000 1000 - 3000 1000 - 3000 3000 (?)
The high level specs, at least those Samsung gives us, points to an unwillingness to sacrifice latency even further in order to shrink die area. The decision makes sense since TLC is already expected to have 50% longer program times than 2bpc MLC. IMFT on the other hand has some latency to give up with its MLC NAND, which is why we see the move to 2x larger page and block sizes with its 128Gbit NAND die. Ultimately that's going to be the comparison that's the most interesting - how Samsung's SSD 840 EVO with its 19nm TLC NAND stacks up to Crucial's M500, the first implementation of IMFT's 128Gbit 20nm MLC NAND.

Modern Features
Along with the NAND update, the EVO also sees a pretty significant controller upgrade. The underlying architecture hasn't changed, Samsung's MEX controller is still based on the same triple-core Cortex R4 design as the previous generation MDX controller. The cores now run at 400MHz compared to 300MHz previously, which helps enable some of the higher performance on the EVO. The MEX controller also sees an update to SATA 3.1, something we first saw with SanDisk's Extreme II. SATA 3.1 brings a number of features, one of the most interesting being support for queued TRIM commands.
The EVO boasts hardware AES-256 encryption, and has its PSID printed on each drive label like Crucial's M500. In the event that you set and lose the drive's encryption key, you can use the PSID to unlock the drive (although all data will be lost). At launch the EVO doesn't support TCG Opal and thus Microsoft's eDrive spec, however Samsung tells us that a firmware update scheduled for September will enable both of these things - again bringing the EVO to encryption feature parity with Crucial's M500.
As one of the world's prominent DRAM makers, it's no surprise to find a ton of DRAM used to cache the firmware and indirection table on the EVO. DRAM size scales with capacity, although Samsung tosses a bit more than is necessary at a couple capacity points (e.g. 250GB).

The move to 19nm 128Gbit TLC NAND die paves the way for some very large drive capacities. Similar to Crucial's M500, the 840 EVO is offered in configurations of up to 1TB.

Pricing
Samsung expects the 840 EVO to be available in the channel at the beginning of August. What we have in the table below are suggested MSRPs, which as long as supply isn't limited usually end up being higher than street prices:
SSD Pricing Comparison - 7/24/2013 120/128GB 240/250/256GB 480/500/512GB 750GB 960GB/1TB Crucial M500 $120.99 $193.56 $387.27 $599.99 Intel SSD 335 $219.99 Samsung SSD 840 $98.44 $168.77 $328.77 Samsung SSD 840 EVO $109.99 $189.99 $369.99 $529.99 $649.99 Samsung SSD 840 Pro $133.49 $230.95 $458.77 SanDisk Extreme II $129.99 $229.77 $449.99 SanDisk Ultra Plus $96.85 $174.29 OCZ Vertex 450 $129.99 $246.84
Prices are a bit higher than the outgoing Samsung SSD 840, which makes sense since we're looking at the beginning of the cost curve of a new process node. Crucial's highly sought after $600 960GB M500 seems finally back in stock just in time for the EVO to go head to head with it. Samsung is expecting roughly a $50 premium for the 1TB EVO over the Crucial solution, but over time I'd expect that gap to shrink down to nothing (or in favor of Samsung). The EVO is considerably more affordable than Samsung's 840 Pro, and the higher capcacity points are at particularly tempting prices.
