Tagged: super-gpu, PowerVR, Imagination Technologies, gt7900
As a preview to announcements and releases being made at both Mobile World Congress (MWC) and the Game Developers Summit (GDC) next week, Imagination Technologies took the wraps off of a new graphics product they are calling a "super-GPU". The PowerVR GT7900 is the new flagship GPU as a part of its Series7XT family that is targeting a growing category called "affordable game consoles." Think about the Android-powered set-top devices like the Ouya or maybe Amazon's Kindle TV.
PowerVR breaks up its GPU designs into unified shading clusters (USCs) and the GT7900 has 16 of them for a total of 512 ALU cores. Imagination has previously posted a great overview of its USC architecture design and how you can compare its designs to other GPUs on the market. Imagination wants to claim that the GT7900 will offer "PC-class gaming experiences" though that is as ambiguous as the idea of a work load of a "console-level game." But with rated peak performance levels hitting over 800 GFLOPS in FP32 and 1.6 TFLOPS in FP16 (half-precision) this GPU does have significant theoretical capability.
|PowerVR GT7900||Tegra X1|
|GPU Clock||800 MHz||1000 MHz|
|Process Tech||16nm FinFET+||20nm TSMC|
Imagination also believes that PowerVR offers a larger portion of its peak performance for a longer period of time than the competition thanks to the tile-based deferred rendering (TBDR) approach that has been "refined over the years to deliver unmatched efficiency."
The FP16 performance number listed above is useful as an extreme power savings option where the half-precision compute operates in a much more efficient manner. A fair concern is how many applications, GPGPU or gaming, actually utilize the FP16 data type but having support for it in the GT7900 allows developers to target it.
Other key features of the GT7900 include support for OpenGL ES 3.1 + AEP (Android Extension Pack), hardware tessellation and ASTC LDR and HDR texture compression standards. The GPU also can run in a multi-domain virtualization mode that would allow multiple operating systems to run in parallel on a single platform.
Imagination believes that this generation of PowerVR will "usher a new era of console-like gaming experiences" and will showcase a new demo at GDC called Dwarf Hall.
I'll be at GDC next week and have already setup a meeting with Imagination to talk about the GT7900 so I can have some hands on experiences to report back with soon. I am continually curious about the market for these types of high-end "mobile" GPUs with the limited market that the Android console market currently addresses. Imagination does claim that the GT7900 is beating products with performance levels as high as the GeForce GT 730M discrete GPU - no small feat.

Dell's Venue 8 7000 tablet sports an 8.4" 2560x1600 OLED display and is powered by the Moorefield based Atom Z3580 SOC, 2GB LPDDR3-1600 with 16GB internal of internal storage with up to a 512GB Micro SD card supported. Even more impressive is that The Tech Report had no issues installing apps or moving files to the SD card with ES File Explorer, unlike many Android devices that need certain programs to reside on the internal storage media. Like Ryan, they had a lot of fun with the RealSense Camera and are looking forward to the upgrade to Lollipop support. Check out The Tech Report's opinion of this impressive Android tablet right here.
"Dell's Venue 8 7000 is the thinnest tablet around, and that's not even the most exciting thing about it. This premium Android slate packs a Moorefield-based Atom processor with quad x86 cores, a RealSense camera that embeds 3D depth data into still images, and a staggeringly beautiful OLED display that steals the show. Read on for our take on a truly compelling tablet."

Once again, NVIDIA brings some really good games to their GRID service, which is currently free for all SHIELD owners. The concept is that NVIDIA will compute the graphics at their server farms, accept your input, and return an audio/video stream of the result. This is a very convenient way to access content, but it cannot replace actual ownership for guaranteed access to specific art that find intrinsically valuable. It can help you discover new content, though.
This week, Saint's Row IV is available to be played on the GRID gaming service. Its predecessor, Saint's Row: The Third, was published on GRID earlier this month. It would be good to play them in order, and they are both worth your time. I did find that the campaign of Saint's Row IV was a bit less unique because the majority of missions were a handful of side-missions strung together, while Saint's Row: The Third had more scenario-based objectives, with the side-missions as an option to build up stats (or just be fun) between these. On the other hand, the movement mechanics were genius in IV. Play them both.
Looking ahead, next Tuesday will be Alan Wake. This is a survival-horror title from Remedy that makes you appreciate just how long your batteries last in real life. Basically, electricity is light and light is a vulnerability for the monsters that want to destroy you. The week after, the third of March, is Metro: Last Light Redux. This is one of the most visually demanding games available, and it is still used as a GPU benchmark at this site.
Saint's Row IV went live last Tuesday, while Alan Wake arrives on the 24th and Metro: Last Light comes in last, on March 3rd.

After a week or so of debate circling NVIDIA's decsision to disable overclocking on mobility GPUs, we have word that the company has reconsidered and will be re-enabling the feature in next month's driver release:
As you know, we are constantly tuning and optimizing the performance of your GeForce PC.
We obsess over every possible optimization so that you can enjoy a perfectly stable machine that balances game, thermal, power, and acoustic performance.
Still, many of you enjoy pushing the system even further with overclocking.
Our recent driver update disabled overclocking on some GTX notebooks. We heard from many of you that you would like this feature enabled again. So, we will again be enabling overclocking in our upcoming driver release next month for those affected notebooks.
If you are eager to regain this capability right away, you can also revert back to 344.75.
Now, I don't want to brag here, but we did just rail NVIDIA for this decision on last night's podcast...and then the decision was posted on NVIDIA's forums just four hours ago... I'm not saying, but I'm just saying!
All kidding aside, this is great news! And NVIDIA desperately needs to be paying attention to what consumers are asking for in order to make up for some poor decisions made in the last several months. Now (or at least soon), you will be able to return to your mobile GPU overclocking!
Flagship. Premium. Best in class. These are the terms that Dell and Intel muttered to me during a conference call to discuss the new Dell Venue 8 7000 tablet. It’s a bullish claim and one that would likely have been received with a sideways eye roll or a shrug had I not been able to get a short amount of hands on time with the device at CES in January. The idea that Dell would develop an Android tablet that bests what more established brands like Nexus and Samsung have created, AND that that same tablet would be powered by an Intel processor rather than a Qualcomm, NVIDIA or Samsung chip would have seemed laughable last year. But after a solid three weeks with the Venue 8 7000 I am prepared to make the statement: this is my favorite tablet. Not my favorite Intel tablet, not my favorite Android tablet: just plain favorite.
The Venue 8 7000 combines style, design, technology and visuals that are simply unmatched by anything else in the Android word and rivals anything that Apple has created to date. There are a couple of warts that center around the camera and gaming performance that won’t drop your jaw, but for the majority of use cases the user experience is as exceptional as the looks.
Maybe best of all, this tablet starts at just $399 and is available today.
Dell Venue 8 7000 Specifications
Let’s begin the review by looking at the raw specifications of the Dell Venue 8 7000. Even though hardware specifications don’t tell a complete story of any device, especially a tablet that is based so much on experience, it is important to get a good baseline expectation.
|Dell Venue 8 7000 (Model 7840)|
|Processor||Intel Atom Z3580 Quad-Core 2.33 GHz|
|Screen||2560x1600 OLED 8.4-in (359 ppi)|
MicroSD Slot (up to 512GB)
|Camera||8MP Rear + Dual 720p Depth
|Wireless||Intel 7260 802.11ac 1x1 Dual Band
|Connection||USB 2.0 (power and data)
|Dimensions||215.8mm x 124.4mm x 6mm
8.5" x 4.88" x 0.24"
The center of the Venue 8 7000 is the Intel Atom Z3580 quad-core processor with a peak clock rate of 2.3 GHz and a base clock rate of 500 MHz. The Z3580 is a 22nm processor based on the Moorefield platform and Silvermont architecture. I first got information about the Silvermont architecture back in May of 2013 so it seems a bit dated in some regards, but the performance and power efficiency is still there to compete with the rival options from ARM.. The Venue 8 7000 includes an LPDDR3-1600 controller and there is 2GB of memory; a decent amount but we are seeing quite a few smartphones with more system memory like the OnePlus One.

ASUS has announced the availability and pricing for the ZenBook UX305, and the specifications are quite exceptional for the price. Not content to compete on hardware specs alone the design of the notebook is a miniscule 0.48” thick, making the UX305 the world’s thinnest ultraportable notebook according to ASUS.
As impressive as the slim profile of the aluminum design might be, it is more impressive to look over the main specifications of the $699 UX305:
- Intel Core M 5Y10 processor
- 8GB of LPDDR3 memory
- 256GB SSD
- 13.3-inch 1920x1080 IPS display (matte finish)
I'll let that sink in for a moment. Quite an impressive list given the MSRP for these specifications is, again, only $699. At this price it's going to be very difficult to beat the UX305 considering what’s under the hood, as this configuration contains double the memory and storage space compared to many ultraportables in this price class. And 1080p IPS on top of everything is just icing on the cake. Battery life should be very good considerin the processor the heart of this is Intel's newest low-power Broadwell-based Core M (the 5Y10), which features HD 5300 graphics and a TDP of just 4.5W. Moreover, the processor is passively cooled and the notebook features a completely fanless design for silent operation.
Since there are no fans to expell heat ASUS has made it a point to promise that the palm rest will always stay cool thanks to their “IceCool technology” (whatever that is - but I really hope it’s an ice cube cooling system). The UX305 is powered by a 45Wh Lithium Polymer battery that has a claimed 10-hour battery life, and the notebook features 802.11ac wireless, three USB 3.0 ports, and includes a USB Ethernet adapter (a nice touch). ASUS is also touting a premium sound system with this notebook, employing a B&O ICEpower amplifier and enhanced with their proprietary “SonicMaster audio”. Rounding out the feature list is an SD card reader and 720p webcam.
The notebook weighs in at 2.6 Lbs, and this configuration of the UX305 is available immediately (listed on their official store). With the surprisingly low MSRP it sounds like this ZenBook will be a solid choice for anyone looking for the latest notebook tech on a budget, and depending on performance and real-world battery life it could just be that mythical MacBook Air "killer" (if you're ok with Windows 8 over OS X, of course).
New Features and Specifications
It is increasingly obvious that in the high end smartphone and tablet market, much like we saw occur over the last several years in the PC space, consumers are becoming more concerned with features and experiences than just raw specifications. There is still plenty to drool over when looking at and talking about 4K screens in the palm of your hand, octa-core processors and mobile SoC GPUs measuring performance in hundreds of GFLOPS, but at the end of the day the vast majority of consumers want something that does something to “wow” them.
As a result, device manufacturers and SoC vendors are shifting priorities for performance, features and how those are presented both the public and to the media. Take this week’s Qualcomm event in San Diego where a team of VPs, PR personnel and engineers walked me through the new Snapdragon 810 processor. Rather than showing slide after slide of comparative performance numbers to the competition, I was shown room after room of demos. Wi-Fi, LTE, 4K capture and playback, gaming capability, thermals, antennae modifications, etc. The goal is showcase the experience of the entire platform – something that Qualcomm has been providing for longer than just about anyone in this business, while educating consumers on the need for balance too.
As a 15-year veteran of the hardware space my first reaction here couldn’t have been scripted any more precisely: a company that doesn’t show performance numbers has something to hide. But I was given time with a reference platform featuring the Snapdragon 810 processor in a tablet form-factor and the results show impressive increases over the 801 and 805 processors from the previous family. Rumors of the chips heat issues seem overblown, but that part will be hard to prove for sure until we get retail hardware in our hands to confirm.
Today’s story will outline the primary feature changes of the Snapdragon 810 SoC, though there was so much detail presented at the event with such a short window of time for writing that I definitely won’t be able to get to it all. I will follow up the gory specification details with performance results compared to a wide array of other tablets and smartphones to provide some context to where 810 stands in the market.

On March 3rd, NVIDIA will host an event called “Made to Game”. Invitations have gone out to numerous outlets, including Android Police, who published a censored screenshot of it. This suggests that it will have something to do with the Tegra X1, especially since the date is the day after Mobile World Congress starts. Despite all of this, I think it is for something else entirely.
Image Credit: Android Police
Allow me to highlight two points. First, Tech Report claims that the event is taking place in San Francisco, which is about as far away from Barcelona, Spain as you can get. It is close to GDC however, which takes also starts on March 2nd. If this was going to align with Mobile World Congress, you ideally would not want attendees to take 14-hour flight for a day trip.
Second, the invitation specifically says: “More than 5 years in the making, what I want to share with you will redefine the future of gaming.” Compare that to the DirectX 12 announcement blog post on March 20th of last year (2014): “Our work with Microsoft on DirectX 12 began more than four years ago with discussions about reducing resource overhead. For the past year, NVIDIA has been working closely with the DirectX team to deliver a working design and implementation of DX12 at GDC ((2014)).”
So yeah, while it might involve the Tegra X1 processor for Windows 10 on mobile devices, which is the only reason I can think of that they would want Android Police there apart from "We're inviting everyone everywhere", I expect that this event is for DirectX 12. I assume that Microsoft would host their own event that involves many partners, but I could see NVIDIA having a desire to save a bit for something of their own. What would that be? No idea.

At 5.7" and 176g the Samsung Note 4 is a large device and it has a resolution to match it at 2560x1440. That resolution does slow it down somewhat, in graphics tests it does fall behind the iPhone 6 Plus except in Basemark X and 3DMark's Ice Storm test but it does show up the competition when it comes to graphical quality with only NVIDIA's Shield beating it on the GFXBench Quality tests. In the CPU tests it scored moderately well on single threaded applications but wipes the floor with the competition when it comes to multi-threaded performance which you should keep in mind when choosing your purchases. To see more benchmarks and details The Tech Report's full review can be found right here.
"Most of the world gets a variant of Samsung's Galaxy Note 4 based on Qualcomm's familiar Snapdragon 805 system-on-a-chip (SoC). In Samsung's home country of Korea, though, the firm ships a different variant of the Note 4 based on Samsung LSI's Exynos 5433 SoC. With eight 64-bit CPU cores and a 64-bit Mali-T760 GPU, the Eyxnos 5433 could make this version the fastest and most capable Note 4--and it gives us some quality time with the Cortex-A53 and A57 CPU cores that will likely dominate the Android market in 2015."

Update: Whoops! The title originally said "374.52", when it should be "347.52". My mistake. Thanks "Suddenly" in the comments!
Two things from NVIDIA this week, a new driver and a new game for the NVIDIA GRID. The new driver aligns with the release of Evolve, which came out on Tuesday from the original creators of Left4Dead. The graphics vendor also claims that it will help Assassin's Creed: Unity, Battlefield 4, Dragon Age: Inquisition, The Crew, and War Thunder. Several SLi profiles were also added for Alone in the Dark: Illumination, Black Desert, Dying Light, H1Z1, Heroes of the Storm, Saint's Row: Gat out of Hell, Total War: Attila, and Triad Wars.
On the same day, NVIDIA released Brothers: A Tale of Two Sons on GRID, bringing the number of available games up to 37. This game came out in August 2013 and received a lot of critical praise. Its control style is unique, using dual-thumbstick gamepads to simultaneously control both characters. More importantly, despite being short, the game is said to have an excellent story, even achieving Game of the Year (2013) for TotalBiscuit based on its narrative, which is not something that he praises often.
I'd comment on the game, but I've yet to get the time to play it. Apparently it is only a couple hours long, so maybe I can fit it in somewhere.
Also, they apparently are now calling this “#SHIELDTuesday” rather than “#GRIDTuesday”. I assume this rebranding is because people may not know that GRID exists, but they would certainly know if they purchased an Android-based gaming device for a couple hundred dollars or more. We could read into this and make some assumptions about GRID adoption rates versus SHIELD purchases, or even purchases of the hardware itself versus their projections, but it would be pure speculation.
Both announcements were made available on Tuesday, for their respective products.
