NVIDIA recently unified its desktop and mobile GPU lineups by moving to a Kepler-based GPU in its latest Tegra K1 mobile SoC. The move to the Kepler architecture has simplified development and enabled the CUDA programming model to run on mobile devices. One of the main points of the opening keynote earlier today was ‘CUDA everywhere,’ and NVIDIA has officially accomplished that goal by having CUDA compatible hardware from servers to desktops to tablets and embedded devices.
Speaking of embedded devices, NVIDIA showed off a new development board called the Jetson TK1. This tiny new board features a NVIDIA Tegra K1 SoC at its heart along with 2GB RAM and 16GB eMMC storage. The Jetson TK1 supports a plethora of IO options including an internal expansion port (GPIO compatible), SATA, one half-mini PCI-e slot, serial, USB 3.0, micro USB, Gigabit Ethernet, analog audio, and HDMI video outputs.
Of course the Tegra K1 part is a quad core (4+1) ARM CPU and a Kepler-based GPU with 192 CUDA cores. The SoC is rated at 326 GFLOPS which enables some interesting compute workloads including machine vision.
In fact, Audi has been utilizing the Jetson TK1 development board to power its self-driving prototype car (more on that soon). Other intended uses for the new development board include robotics, medical devices, security systems, and perhaps low power compute clusters (such as an improved Pedraforca system).It can also be used as a simple desktop platform for testing and developing mobile applications for other Tegra K1 powered devices, of course.
Beyond the hardware, the Jetson TK1 comes with the CUDA toolkit, OpenGL 4.4 driver, and NVIDIA VisionWorks SDK which includes programming libraries and sample code for getting machine vision applications running on the Tegra K1 SoC.
The Jetson TK1 is available for pre-order now at $192 and is slated to begin shipping in April. Interested developers can find more information on the NVIDIA developer website.
Maxwell and Kepler and...Fermi?
Covering the landscape of mobile GPUs can be a harrowing experience. Brands, specifications, performance, features and architectures can all vary from product to product, even inside the same family. Rebranding is rampant from both AMD and NVIDIA and, in general, we are met with one of the most confusing segments of the PC hardware market.
Today, with the release of the GeForce GTX 800M series from NVIDIA, we are getting all of the above in one form or another. We will also see performance improvements and the introduction of the new Maxwell architecture (in a few parts at least). Along with the GeForce GTX 800M parts, you will also find the GeForce 840M, 830M and 820M offerings at lower performance, wattage and price levels.
With some new hardware comes a collection of new software for mobile users, including the innovative Battery Boost that can increase unplugged gaming time by using frame rate limiting and other "magic" bits that NVIDIA isn't talking about yet. ShadowPlay and GameStream also find their way to mobile GeForce users as well.
Let's take a quick look at the new hardware specifications.
|GTX 880M||GTX 780M||GTX 870M||GTX 770M|
|GPU Code name||Kepler||Kepler||Kepler||Kepler|
|Rated Clock||954 MHz||823 MHz||941 MHz||811 MHz|
|Memory||Up to 4GB||Up to 4GB||Up to 3GB||Up to 3GB|
|Memory Clock||5000 MHz||5000 MHz||5000 MHz||4000 MHz|
Both the GTX 880M and the GTX 870M are based on Kepler, keeping the same basic feature set and hardware specifications of their brethren in the GTX 700M line. However, while the GTX 880M has the same CUDA core count as the 780M, the same cannot be said of the GTX 870M. Moving from the GTX 770M to the 870M sees a significant 40% increase in core count as well as a jump in clock speed from 811 MHz (plus Boost) to 941 MHz.
It wouldn’t be February if we didn’t hear the Q4 FY14 earnings from NVIDIA! NVIDIA does have a slightly odd way of expressing their quarters, but in the end it is all semantics. They are not in fact living in the future, but I bet their product managers wish they could peer into the actual Q4 2014. No, the whole FY14 thing relates back to when they made their IPO and how they started reporting. To us mere mortals, Q4 FY14 actually represents Q4 2013. Clear as mud? Lord love the Securities and Exchange Commission and their rules.
The past quarter was a pretty good one for NVIDIA. They came away with $1.144 billion in gross revenue and had a GAAP net income of $147 million. This beat the Street’s estimate by a pretty large margin. As a response, trading of NVIDIA’s stock has gone up in after hours. This has certainly been a trying year for NVIDIA and the PC market in general, but they seem to have come out on top.
NVIDIA beat estimates primarily on the strength of the PC graphics division. Many were focusing on the apparent decline of the PC market and assumed that NVIDIA would be dragged down by lower shipments. On the contrary, it seems as though the gaming market and add-in sales on the PC helped to solidify NVIDIA’s quarter. We can look at a number of factors that likely contributed to this uptick for NVIDIA.

How about some fresh graphics card rumors for your Tuesday afternoon? The folks at VideoCardz.com have collected some information about two potential NVIDIA GeForce cards that are going to hit your pocketbook hard. If the mid-range GPU market was crowded wait until you see the changes NVIDIA might have for you soon on the high-end.
First up is the NVIDIA GeForce GTX TITAN Black Edition, a card that will actually have the same specifications as the GTX 780 Ti but with full performance double precision floating point and a move from 3GB to 6GB of memory. The all-black version of the GeForce GTX 700-series cooler is particularly awesome looking.
Image from VideoCardz.com
The new TITAN would sport the same GPU as GTX 780 Ti, only TITAN BLACK would have higher double precision computing performance, thus more FP64 CUDA cores. The GTX TITAN Black Edition is also said to feature 6GB memory buffer.This is twice as much as GTX 780 Ti, and it pretty much confirms we won’t be seeing any 6GB Ti’s.
The rest is pretty much well known, TITAN BLACK has 2880 CUDA cores, 240 TMUs and 48 ROPs.
VideoCardz.com says this will come in at $999. If true, this is a pure HPC play as the GTX 780 Ti would still offer the same gaming performance for enthusiasts.
Secondly, there looks to be an upcoming dual-GPU graphics card using a pair of GK110 GPUs that will be called the GeForce GTX 790. The specifications that VideoCardz.com says they have indicate that each GPU will have 2496 enabled CUDA cores and a smaller 320-bit memory interface with 5GB designated for each GPU. Cutting back on the memory interface, shader counts and even clocks speeds would allow NVIDIA to manage power consumption at the targeted 300 watt level.

Head over to VideoCardz.com for more information about these rumors but if all goes as they expect, you'll hear about these products quite a bit more in February and March.
What do you think? Are these new $1000 graphics cards something you are looking forward to?

Project X Logan K1 is the first big news out of CES from NVIDIA and represents a bit of a change from what we were expecting. The current belief was that the SoC would have four 28nm Cortex A15 processors but that will only be one flavour of K1, a Denver based dual core version will also be released. Those ARMv8 64-bit processors will natively handle 64 bit applications while the A15 version that The Tech Report had taken pictures of will be limited to 32 bit applications, though that will not matter in many mobile applications. You should also check out Ryan's deep dive into the new Denver and Kepler version here.
"In early 2011, during a CES press event, Nvidia revealed its Project Denver CPU initiative. On Sunday evening, at another CES press conference, the company provided a glimpse of the first Denver-based processor: the Tegra K1. This next-generation SoC features dual Denver CPU cores clocked at up to 2.5GHz. The cores were designed by Nvidia, and they're compatible with the 64-bit ARMv8 instruction set. They have a seven-way superscalar pipeline and a hefty 192KB of L1 cache."

Once known as Logan, now known as K1
NVIDIA has bet big on Tegra. Since the introduction of the SoC's first iteration, that much was clear. With the industry push to mobile computing and the decreased importance of the classic PC design, developing and gaining traction with a mobile processor was not only an expansion of the company’s portfolio but a critical shift in the mindset of a graphics giant.
The problem thus far is that while NVIDIA continues to enjoy success in the markets of workstation and consumer discrete graphics, the Tegra line of silicon-on-chip processors has faltered. Design wins have been tough to come by. Other companies with feet already firmly planted on this side of the hardware fence continue to innovate and seal deals with customers. Qualcomm is the dominant player for mobile processors with Samsung, MediaTek, and others all fighting for the same customers NVIDIA needs. While press conferences and releases have been all smiles and sunshine since day one, the truth is that Tegra hasn’t grown at the rate NVIDIA had hoped.
Solid products based on NVIDIA Tegra processors have been released. The first Google Nexus 7 used the Tegra 3 processor, and was considered the best Android tablet on the market by most, until it was succeeded by the 2013 iteration of the Nexus 7 this year. Tegra 4 slipped backwards, though – the NVIDIA SHIELD mobile gaming device was the answer for a company eager to show the market they built compelling and relevant hardware. It has only partially succeeded in that task.
With today’s announcement of the Tegra K1, previously known as Logan or Tegra 5, NVIDIA hopes to once again spark a fire under partners and developers, showing them that NVIDIA’s dominance in the graphics fields of the PC has clear benefits to the mobile segment as well. During a meeting with NVIDIA about Tegra K1, Dan Vivoli, Senior VP of marketing and a 16 year employee, equated the release of the K1 to the original GeForce GPU. That is a lofty ambition and puts of a lot pressure on the entire Tegra team, not to mention the K1 product itself, to live up to.
Tegra K1 Overview
What we previously knew as Logan or Tegra 5 (and actually it was called Tegra 5 until just a couple of days ago), is now being released as the Tegra K1. The ‘K’ designation indicated the graphics architecture that powers the SoC, in this case Kepler. Also, it’s the first one. So, K1.
The processor of the Tegra K1 look very familiar and include four ARM Cortex-A15 “r3” cores and 2MB of L2 cache with a fifth A15 core used for lower power situations. This 4+1 design is the same that was introduced with the Tegra 4 processor last year and allows NVIDIA to implement a style of “big.LITTLE” design that is unique. Some slight modifications to the cores are included with Tegra K1 that improve performance and efficiency, but not by much – the main CPU is very similar to the Tegra 4.
NVIDIA also unveiled late last night that another version of the Tegra K1 that replaces the quad A15 cores with two of the company's custom designs Denver CPU cores. Project Denver, announced in early 2011, is NVIDIA's attempt at building its own core design based on the ARMv8 64-bit ISA. This puts this iteration of Tegra K1 on the same level as Apple's A7 and Qualcomm's Krait processors. When these are finally available in the wild it will be incredibly intriguing to see how well NVIDIA's architects did in the first true CPU design from the GPU giant.

Update: Check out our more in-depth analysis of the Tegra K1 processor from NVIDIA.
Today during its CES 2014 press conference, NVIDIA announced the Tegra K1 SoC as the successor to the Tegra 4 processor. This new ARM-based part includes 192 Kepler-based CUDA cores, sharing the same GPU architecture as the current GeForce GTX 700-series discrete graphics cards.
NVIDIA also announced the Epic has Unreal Engine 4 up and running on the Tegra K1, bringing an entirely new class of games to mobile Android devices. We got to see some demonstrations from NVIDIA running on the K1 and I must admit the visuals were stunning. Frame rates did get a bit choppy during the subway demo of UE4 but it's still early.
As an added surprise, NVIDIA is announcing a version of Tegra K1 that ships with the same quad-core A15 (4+1) design as the Tegra 4 BUT ALSO have a version that uses two NVIDIA Denver CPU cores!! Denver is NVIDIA's custom CPU design based on the ARMv8 architecture, adding 64-bit support to another ARM partner's portfolio.
Tegra K1 is offered in two pin-to-pin compatible versions - a 32-bit quad-core (4-Plus-1 ARM Cortex-A15 CPU) and a custom, NVIDIA-designed 64-bit dual Super Core CPU. This CPU (codenamed “Project Denver”) delivers very high single-thread and multi-thread performance. Both versions deliver stunning graphics and visual computing capabilities powered by the 192-core NVIDIA Kepler GPU.
NVIDIA has only had Denver back for a few days from the fab but there able to showcase it running Android. It's been a long time since the initial announcement of this project and its great to finally see a result.
Tegra K1 with quad-core A15 processor
We'll have an in-depth story on the Tegra K1 on Monday morning, 6am PST right here on PC Perspective so check back then!!

EVGA Brings Custom GTX 780 Ti Early
Reference cards for new graphics card releases are very important for a number of reasons. Most importantly, these are the cards presented to the media and reviewers that judge the value and performance of these cards out of the gate. These various articles are generally used by readers and enthusiasts to make purchasing decisions, and if first impressions are not good, it can spell trouble. Also, reference cards tend to be the first cards sold in the market (see the recent Radeon R9 290/290X launch) and early adopters get the same technology in their hands; again the impressions reference cards leave will live in forums for eternity.
All that being said, retail cards are where partners can differentiate and keep the various GPUs relevant for some time to come. EVGA is probably the most well known NVIDIA partner and is clearly their biggest outlet for sales. The ACX cooler is one we saw popularized with the first GTX 700-series cards and the company has quickly adopted it to the GTX 780 Ti, released by NVIDIA just last week.
I would normally have a full review for you as soon as we could but thanks to a couple of upcoming trips that will keep me away from the GPU test bed, that will take a little while longer. However, I thought a quick preview was in order to show off the specifications and performance of the EVGA GTX 780 Ti ACX.
As expected, the EVGA ACX design of the GTX 780 Ti is overclocked. While the reference card runs at a base clock of 875 MHz and a typical boost clock of 928 MHz, this retail model has a base clock of 1006 MHz and a boost clock of 1072 MHz. This means that all 2,880 CUDA cores are going to run somewhere around 15% faster on the EVGA ACX model than the reference GTX 780 Ti SKUs.
We should note that though the cooler is custom built by EVGA, the PCB design of this GTX 780 Ti card remains the same as the reference models.

Here is a roundup of the reviews of what is now the fastest single GPU card on the planet, the GTX 780 Ti, which is a fully active GK110 chip. The 7GHz GDDR5 is faster than AMD's memory but use a 384-bit memory bus which is less than the R9 290X which leads to some interesting questions about the performance of this card under high resolutions. Are you willing to pay quite a bit more for better performance and a quieter card? Check out the performance deltas at [H]ard|OCP and see if that changes your mind at all.
You can see how it measures up in ISUs in Ryan's review as well.
"NVIDIA's fastest single-GPU video card is being launched today. With the full potential of the Kepler architecture and GK110 GPU fully unlocked, how will it perform compared to the new R9 290X with new drivers? Will the price versus performance make sense? Will it out perform a TITAN? We find out all this and more."
