1. That is a false claim - Gamenab didn't even cite the correct FPGA model when he made that DRM claim.
2. G-Sync is actually good down to 1 FPS - it adaptively inserts additional redraws in between frames at rates below 30, as to minimize the possibility of judder (incoming frame during an already started panel refresh pass). FreeSync (it its most recently demoed form) reverts back to the VSYNC setting at the low end. Further, you are basing the high end of G-Sync only on the currently released panels. Nothing states the G-Sync FPGA tops out at 144.
3. I use the word 'experience' because it is 'my experience' - I have personally witnessed most currently shipping G-Sync panels as well as the FreeSync demo at this past CES. I have also performed many tests with G-Sync. Source: I have written several articles about this, including the one linked in this post.
5. I believe the reason it is not yet released is because Nvidia wants to be able to correctly cover more of the range (including the low range / what happens when the game engine hitches).

Gamenab stumbled across the leaked driver and tried to use it to spread a bunch of conspiracy theory FUD. I hope most people here can correctly apply Occam's razor as opposed to the alternative, which is that he supposedly designed those changes, those changes going into an internal driver build that was inadvertently leaked and happened to apply to the exact laptop he already owned.

1. The FPGA *was* required for the tech to work on the desktop panels it was installed in.
2. FreeSync (as I've witnessed so far) as well as the most recent adaptive sync can not achieve the same result across as wide of a refresh rate range that G-Sync currently can.
3. Nvidia could 'make it work', but it would not be the same experience as can be had with a G-Sync module, even with an adaptive sync panel (as evidenced by how this adaptive sync panel in this laptop intermittently blanks out at 30 FPS or when a game hitches.
4. ...
5. The driver was not a release driver, and was not meant to call the experience it gives 'G-Sync'. It was meant to be internal.

Conclusion - Adaptive sync alone is not the same experience you can currently get with a real G-Sync panel, which is why any possible future G-Sync that does not need a module it's not yet a real thing.

Submission + - Multi-Display Gaming Artifacts Shown with AMD, 4K Affected Too (pcper.com)

Vigile writes: Multi-display gaming has really found a niche in the world of high-end PC gaming, starting when AMD released Eyefinity in 2009 in three panel configurations. AMD expanded out to 6 screen options in 2010 and NVIDIA followed shortly thereafter with a similar multi-screen solution called Surround. Over the last 12 months or so GPU performance testing has gone through a sort of revolution as the move from software measurement to hardware capture measurement has taken hold. PC Perspective has done testing with this new technology on AMD Eyefinity and NVIDIA Surround configurations at 5760x1080 resolution and found there were some substantial anomalies in the AMD captures. The AMD cards exhibited dropped frames, interleaved frames (jumping back and forth between buffers) and even stepped, non-horizontal vertical sync tearing. The result is a much lower observed frame rate than software like FRAPS would indicate and these problems will also be found when using the current top end dual-head 4K PC displays since they emulate Eyefinity and Surround for setup.

Submission + - Console Manufacturers Want the Impossible?

Phopojijo writes: Consoles have not really been able to profitably scale over the last decade or so. Capital is sacrificed to gain control over their marketshare and, even with the excessive lifespan of this recent generation, cannot generate enough revenue with that control to be worth it. Have we surpassed the point where closed platforms can be profitable and will we need to settle on an industry body, such as W3C or Khronos, to fix a standard for companies to manage slices of and compete within?

Submission + - OpenCL has a competitor: Microsoft C++ AMP (pcper.com)

Phopojijo writes: "Microsoft was at AMD's Fusion Developer Summit with a keynote this morning outlining Microsoft's part in the unified computing initiative. Currently your options for easily utilizing all your computing power are limited to Apple-founded OpenCL maintained by the Khronos Group. Microsoft's alternative is called C++ Accelerated Massive Parallelism (or C++ AMP). Microsoft was clear to announce that C++ AMP would be an open specification. Any interested compiler developer would be allowed to support this specification."

Comment How about 4x 2.5" hot swap SSD's up front? (Score 2, Interesting) 366

I've been using one of these for over a year. Handy for having your OS on a 4x SSD RAID. Uses only one 5.25" bay:


Be sure to get the beefier model (with the fans) if you want to use 4x VRaptors.

Apple's description of the zeroing format method we used fits the description of what we wanted in terms of resetting the SSD to a clean state

Zeroing is not the same operation as TRIM. TRIM marks a block as unused, and if you read it you'll either get random data, or zeros (probably the later). Zeroing marks it as in-use, and if you read it you'll get zeros. The SSD's wear management algorithm will move the latter around as though it were real data, whereas it knows the former is "empty" so it won't bother (so the SSD will be faster). In other words, they don't seem to be using a "clean state" at all, which would explain why there's no difference.

Not only that, but writing to all free space of many SSD's will *drop* their IOPS performance since the drive now has to track *all* sectors in the LBA remap table. This is especially true with Intel drives (even the 2nd gen). Additionally, without TRIM, most drives will then continue to track all LBA's as long as used in that same Mac.

Secondly, the SSD in the Macbook Air really isn't very fast at all

A Macbook Air is just about the worst test of SSD performance, as its SATA and other busswork is run in a much reduced power mode, meaning the bottleneck is not the SSD at all. A worst-case degraded SSD in an Air will still be faster than the other bottleneck in that system.

Submission + - RevoDrive PCIe SSD Tops Performance at Lower Costs (pcper.com)

Vigile writes: PCI Express-based solid state drives are not new but getting one at a price a consumer might be willing to pay IS new. OCZ's RevoDrive combines a pair of SandForce 1200 controllers behind a basic RAID controller and eventually terminates at a PCI Express x4 connection with a capacity as high as 240GB. The key to the product is not just its absurdly impressive performance that nearly matches the ioXtreme card from Fusion-io and pushes almost 500 MB/s but also its price. The RevoDrive will cost almost the same as a standard SandForce-based 2.5-in SSD making it the fastest consumer storage option for the price. PC Perspective has a full performance evaluation that compares the RevoDrive to other PCIe SSDs and 2.5-in models to give a balanced view and still comes away truly impressed with the unit.

Submission + - Some SSDs could get 20% capacity boost for free (pcper.com)

Vigile writes: After impressing the storage world with raw speed, certain models of Sandforce-based SSDs may be able to get a free upgrade in capacity of about 20%. OCZ has worked with the SSD controller vendor to tweak the firmware in such a way to permit less overprovisioning on the flash memory without incurring a drop in performance. PC Perspective has tested one such prototype drive that has the exact same design but is provisioned at 120GB rather than 100GB all with a firmware update. Even better, OCZ claims that users of their Sandforce-based drives will likely be able to upgrade their own drives soon as well.

Submission + - New AMD 6-core CPUs Finally Compete with Intel (pcper.com)

Vigile writes: AMD has been having a difficult time in the last year or so keeping up with Intel on the consumer CPU front. While the Phenom processors have been decent, since the introduction of Intel's Core i5 and Core i7 lineup of parts AMD has never really had a chance in the performance segment. They are hoping to change that with the release of the Phenom II X6 1090T processor, a 6-core CPU that will sell for about $285. Compare that to the 6-core offering from Intel: the Core i7-980X that retails for $999 or above. No, the 1090T won't run as fast in the benchmarks as the i7-980X but it does do well in media encoding tests and is one of the best available CPUs for performance/watt and performance/dollar. Add to that mixture the new Turbo Core Technology that automatically takes the 3.2 GHz part up to 3.6 GHz when three or fewer cores are loaded, and the AMD 1090T is the best competition Intel has seen in some time.

Submission + - FirePro V8800 Offers Top Performance, 4 Displays (pcper.com)

Vigile writes: Workstation class graphics cards have always been expensive and the new AMD FirePro V8800 is no exception with an estimated street price of $1499 that puts it in line with previous high-end professional releases. For that price you get a 40nm GPU running at 825 MHz with 2GB of GDDR5 memory along with support for up to four discrete displays, OpenGL 4.0, DX11 and more. This GPU is basically the same as the one used in the Radeon HD 5800-series of cards and brings the FirePro line well ahead of the top NVIDIA Quadro offerings in terms of performance. PC Perspective pits the new FirePro V8800 against the previous generation from AMD, the V8700, as well as the Quadro FX 4800 card that sells in the identical price bracket.

Submission + - New VelociRaptor HDD Returns to take on SSDs (pcper.com)

Vigile writes: While solid state drives, including those from Western Digital itself, continue to be the star of storage technology today, platter-based traditional hard drives still remain the device of choice for most storage. Before there were SSDs, enthusiasts and PC gamers depended on the Western Digital VelociRaptor brand to keep their computers fast and the brand is back with a new 600GB SATA 6Gb/s model released today. Although seek, noise and power ratings remain nearly identical to the previous model there is a nice boost in transfer rates over other standard hard drives. As for price, the new VelociRaptor's cost per GB makes it a better deal than previous iterations though it remains well behind the ratio of any of the tested 2TB hard drives.
