Tagged: pcie 4.0, pcie, PCI SIG
You know the PCI-SIG might break the pattern with PCIe 5.0, just to mess with us. But for right now, Tom's Hardware seems to have acquired part of the PCIe 4.0 spec and it is expected to get 2 GB/s bandwidth per lane, per direction. This is double the bandwidth of PCIe 3.0, continuing the trend of each major PCIe release doubling bandwidth of the previous major version.
A 16-lane PCIe 4.0-compliant graphics card or storage add-in board (that feels so weird to write...) has a maximum bandwidth of 32 GB/s inbound and 32 GB/s outbound, 64 GB/s total. This is still below GDDR5 bandwidth, but approaching the same order of magnitude. That said, memory bandwidth is the major roadblock for optimizing GPGPU workloads, already. APUs will probably still have an advantage in CPU and GPU tag-teaming tasks, despite their lower compute performance.
According to bit-tech, the spec is expected to arrive with Skylake and its 100-series chipset.

Shortly after the Kinect deprecation, Microsoft has announced that a 10% boost in GPU performance will be coming to Xbox One. This, of course, is the platform allowing developers to avoid the typical overhead which Kinect requires for its various tasks. Updated software will allow game developers to regain some or all of that compute time back.
Still looks like Wall-E grew a Freddie Mercury 'stache.
While it "might" (who am I kidding?) be used to berate Microsoft for ever forcing the Kinect upon users in the first place, this functionality was planned from before launch. Pre-launch interviews stated that Microsoft was looking into scheduling their compute tasks while the game was busy, for example, hammering the ROPs and leaving the shader cores idle. This could be that, and only that, or it could be a bit more if developers are allowed to opt out of most or all Kinect computations altogether.
The theoretical maximum GPU compute and shader performance of the Xbox One GPU is still about 29% less than its competitor, the PS4. Still, 29% less is better than about 36% less. Not only that, but the final result will always come down to the amount of care and attention spent on any given title by its developers. This will give them more breathing room, though.
Then, of course, the PC has about 3x the shader performance of either of those systems in a few single-GPU products. Everything should be seen in perspective.

MSI has just announced an updated all-in-one PC which they hope you find... Adora-able? If you thought that joke was terrible, then it gets worse: I stole it from their product page. The Adora20 3M is based on an AMD E2-3800, which is a quad-core Kabini APU. Its built-in Radeon HD 8280 will not be able to play most modern games as it is unable to keep 30 FPS in either DOTA 2 or Diablo III at the screen's native (1600x900) resolution. This will be a GPU for web browsing and video decoding tasks.
The device, itself, is built into a 19.5-inch touchscreen display and comes with Windows 8.1. It has two integrated 3W speakers from Creative and a one-megapixel webcam. It also has mic in, headphone out, a pair of USB 3.0 ports, two more pairs of USB 2.0 ports (one pair on the side and one pair on the back), an HDMI-out port, gigabit Ethernet, and an SD card reader (no maximum card size listed). It also has Wireless-N. An SSD will be available on some units, but not every one. A TV tuner is also optional.
The Adora design is marketed as a slim design that about nine-tenths (9/10) of an inch at its thickest. The point seems to be that it is a full desktop PC in a TV form factor. They do not mention whether it supports VESA wall mounts (and its pictures suggest that it does not). Its kickstand looks handy, but I cannot really find a compelling reason for a thin monitor that is just going to lean on its kickstand all day.
It could be a good deal, however, if it is priced appropriately. Unfortunately, we do not have details on pricing or availability yet. If cheap enough, this could be very compelling for a kiosk or a kitchen/office nook. I still question whether those use cases would care about it being less than an inch thick, but I guess it would be a nice bonus.

If your obsession over Titanfall, regardless of platform, has taken over your mind and you need a way to physically display that fact, then Turtle Beach has the headset for you! Titanfall Ear Force Atlas! Apply directly to the forehead!
Branding aside these headphones are quite stiff, which may become uncomfortable after time but presented an unexpected benefit for the Kitguru tester who happens to have an Occulus Rift; they do not shift or creak as your head quickly moves in reaction to an in game event. The bass is a bit strong for some purposes but will make your Titan sound even more impressive; the sound is perhaps a bit muddy but not enough to ruin your experience while gaming or watching movies. Check out the full review here.
"If you find yourself jumping from rooftop to rooftop, wallrunning your way between kills and blasting away at 30ft tall metal behemoths on a regular basis you are either playing Titanfall or need to reduce your meds. Either way though, you will probably appreciate the style of Turtle Beach’s latest headset, the Titanfall Ear Force Atlas headset. It’s compatible with the Xbox 360, Xbox One and PC, with adapters, cables and connectors galore – but does it sound good? That’s what’s important and that’s what we are here to find out."

HP is courting mobile users with their Pro x2 series, a stylus enabled tablet with a keyboard dock containing extra outputs and a second battery in 1080p 12.5" and 11.6" 1366x768 flavours; the smaller model is already available already starting at $850. EVGA stepped up their game with the 1600W SuperNOVA PSU that comes with a 10 year warranty while Fractal Design was showing off refillable and expandable self contained watercoolers. You can also catch AData's new SSDs and Kingston's M.2 SSDs and even more over at The Tech Report.
"PC makers appear to be embracing the convertible tablet form factor with gusto at Computex 2014, and HP is no exception. Today, the company announced a pair of business-focused two-in-ones: the Pro x2 612 and Pro x2 410."

So this mouse has many buttons. It even has not-buttons. The ROCCAT Tyon has 31 user-customizable functions mapped over 16 buttons. The "Tyon Xcelerator", near its thumb buttons, is an analog switch designed for functions such as throttle or vertical movement. The "Dorsal Fin" is a switch that tilts left and right, like a tilt wheel, except that it also has a tilting mouse wheel.
I guess you can never have too many tilt functions.
Yo Cat, Heard You Like Buttons...
In short, ROCCAT has basically put as many functions on that mouse as they believe comfortable. Personally, I think the "Xcelerator" could be quite useful for games, like Battlefield: Bad Company 2 with its UAV, where you need to move in three dimensions and rotate in two dimensions, at the same time. That just leaves about 30 other functions to think about.
The ROCCAT Tyon is "coming soon" for 99.99 Euros (~$136 USD).

Tagged: tegra k1, tegra, project tango, nvidia, google, Android
Today, Google announced their "Project Tango" developer kit for tablets with spatial awareness. With a price tag of $1,024 USD, it is definitely aimed at developers. In fact, the form to be notified about the development kit has a required check box that is labeled, "I am a developer". Slightly above the form is another statement, "These development kits are not a consumer device and will be available in limited quantities".
So yes, you can only buy these if you are a developer.
The technology is the unique part. Project Tango is aimed at developers to make apps which understand the 3D world around the tablet. Two examples categories they have already experimented with are robotics and computer vision. Of course, this could also translate to alternate reality games and mapping.
While Google has not been too friendly with OpenCL in its Android platform, it makes sense that they would choose a flexible GPU with a wide (and deep) range of API support. While other SoCs are probably capable enough, the Kepler architecture in the Tegra K1 is about as feature-complete as you can get in a mobile chip, because it is basically a desktop chip.
Google's Project Tango is available to developers, exclusively, for $1,024 and ships later this month.
Also, that price is clearly a pun.

Tagged: amd, asmedia, asus, rumour
DigiTimes spilled a juicy rumour today which has AMD looking to a work even more closely with ASMedia in the future. AMD has already partnered with this ASUS subsidiary to integrate SATA Express into their newest chips as a way to save development costs and ease production issues. This goes along with AMD's fabless strategy that started with the split off of GLOBALFOUNDRIES and has since lead to partnerships with other major fabbers like TSMC. While still very much in the rumour phase and with AMD refusing to comment we are not sure this will indeed occur but it does fit with AMD's current strategy of price reductions and may free up their engineers to work on more specialized designs.
"AMD reportedly is planning to outsource its PC chipset R&D to ASMedia Technology, a subsidiary of Asustek Computer, to save costs and the cooperation is expected to greatly benefit ASMedia's revenue performance, according to sources from the upstream supply chain."

Well that was an alphabet soup of a title.
Samsung has just announced a new line of SSDs, based on three bit per cell (TLC) memory, for enterprise customers. The Samsung 845DC EVO is rated at 530MB/s reads with 87,000 IOPS. The company will also cover up to 600TB of writes under its warranty (no mention of length in years, though). The drive will be available "later this month" in 240GB, 480GB, and 960GB models. Samsung did not mention price in their press release, but Anandtech claims the 240GB will be $250, the 480GB will be $490, and the 960GB will be $969.
Samsung's SSDs will give you some TLC???
This is basically $1/GB scaling, plus $10. I must admit, this is getting pricy. In the consumer space, we have recently seen 512GB for $199. That said, SSDs are not known for sticking to their MSRP. Also, these are enterprise-rated drives. Being TLC-based, I wonder how much (if any) SLC-style write cache was included, as per the consumer 840 EVO.
Lastly, Samsung claims that these drives use around 4W under load. This is much lower than hard drives but a little high for SSDs, according to benchmarks that I have seen. That said, there are a few ways to parse that (for example, if they mean that its peak is typically 4W, which would be pretty good for a 960GB drive).
The Samsung 845DC EVO will be available later this month for a little over $1/GB.
