Tegra K1 is NVIDIA's new mobile processor and this first to implement the Kepler graphics architecture. In other words, it has all of the same graphics functionality as a desktop GPU with 364 GigaFLOPs of performance (a little faster than a GeForce 9600 GT). This is quite fast for a mobile product. For instance, that amount of graphics performance could max out Unreal Tournament 3 to 2560x1600 and run Crysis at 720p. Being Kepler, it supports OpenGL 4.4, OpenGL ES 3.1, DirectX 11 and 12, and GPU compute languages.
Xiaomi is launching their MiPad in Beijing, today, with an 8-inch 2048x1536 screen and the Tegra K1. They will be available in June (for China) starting at $240 USD for the 16GB version and going up to $270 for the 64GB version. Each version has 2GB of RAM, an 8MP rear-facing camera, and a 5MP front camera.
Now, we wait and see if any Tegra K1 devices come to North America and Europe - especially at that price point.

What would Gordon Freeman do? He would tell everyone to... ... oh right.
Well, apparently he is available on the NVIDIA SHIELD, now, along with Portal. I am not talking about GameStream. These two games have been ported to Android, but only through the SHIELD. From their screenshots, the mobile games look pretty good, especially Portal with its look-through mechanics.
As usual, whenever NVIDIA really wants something, they will often parachute engineers through your skylights to do it for you. The company revolves around delivering experiences to their customers, which is a good mindset for a company to have. This is one of the main reasons for Microsoft and the success of PC gaming, especially in the late 90's with their DirectX efforts.
If you have an NVIDIA SHIELD, Half Life 2 and Portal are available now for $9.99, through TegraZone.

To a crowd of press and developers at their GTC summit, NVIDIA announced the GeForce GTX Titan Z add-in board (AIB). Each of the two, fully unlocked, GK110 GPUs would each have access to 6GB of GDDR5 memory (12GB total). The card was expected to be available on May 8th but has yet to surface. As NVIDIA has yet to comment on the situation, many question whether it ever will.
And then we get what we think are leaked benchmarks (note: two pictures).
One concern about the Titan Z was its rated 8 TeraFLOPs of compute performance. This is a fairly sizable reduction from the theoretical maximum of 10.24 TeraFLOPs of two Titan Black processors and even less than two first-generation Titans (9 TeraFLOPs combined). We expected that this is due to reduced clock rates. What we did not expect is for benchmarks to show the GPUs boost way above those advertised levels, and even beyond the advertised boost clocks of the Titan Black and the 780 Ti. The card was seen pushing 1058 MHz in some sections, which leads to a theoretical compute performance of 12.2 TeraFLOPs (6.1 TeraFLOPs per GPU) in single precision. That is a lot.
These benchmarks also show that NVIDIA has a slight lead over AMD's R9 295X2 in many games, except Battlefield 4 and Sleeping Dogs (plus 3DMark and Unigine). Of course, these benchmarks measure the software reported frame rate and frame times and those may or may not be indicative of actual performance. While I would say that the Titan Z appears to have a slight performance lead over the R9 295X2, although a solid argument for an AMD performance win exists, it does so double the cost (at its expected $3000 USD price point). That is not up for debate.
So, until NVIDIA says anything, the Titan Z is in limbo. I am sure there exists CUDA developers who await its arrival. Personally, I would just get three Titan Blacks since you are going to need to manually schedule your workloads across multiple processors anyway (or 780 Tis if 32-bit arithmetic is enough precision). That is, of course, unless you cannot physically fit enough GeForce Titan Blacks in your motherboard and, as such, you require two GK110 chips per AIB (but not enough to bother writing a cluster scheduling application).

Remember that cake we got last week? It was sent by NVIDIA to celebrate the release of Portal (May 12th) on SHIELD. They are at it again...
When you get a FedEx box meant for a poster or tube of some kind, but you didn't order said poster, you are likely to be confused. Imagine my surprise when I opened it up and found...a bright green crowbar. This might become a habit for them; we received a pry bar from NVIDIA in April of 2012 to tease the release of the GeForce GTX 690.
Based on the message on the crow bar it seems that a Half-Life 2 release on SHIELD is going to be following soon. Sorry to disappoint anyone that was expecting Half-Life 3...

Externally-attached GPUs have been a topic for many years now. Numerous companies have tried, including AMD and Lucid, but no solution has ever been a widely known and available product. Even as interfaces increase in bandwidth and compatibility with internal buses, it has never been something that a laptop salesperson could suggest to users who want to dock into a high-performance station at home. At best, we are seeing it in weird "coin mining" racks to hang way more GPUs above a system than could physically mount on the motherboard.
Apparently that has not stopped the DIY community, according to chatter on Tech Inferno forums. While the above video does not really show the monitor, MacBook Pro, and GPU enclosure at the same time, let alone all wired together and on, it seems reasonable enough. The video claims to give the MacBook Pro (running Windows 8.1) access to a GeForce GTX 780 Ti with fairly high performance, despite the reduced bandwidth. Quite cool.

NVIDIA has released version 2.0.1 of GeForce Experience. This update does not bring many new features, hence why it is a third-level increment to the version number, but is probably worthwhile to download regardless. Its headlining feature is security enhancements with OpenSSL under remote GameStream on SHIELD. The update also claims to improve streaming quality and reduce audio latency.
While they do not seem to elaborate, I assume this is meant to fix Heartbleed, which is an exploit that allows an attacker to receive a small snapshot of active memory. If that is that case, it is unclear whether the SHIELD, the host PC during a game session, or both endpoints are affected.
The new GeForce Experience is available at the NVIDIA website. If it is running, it will also ask you to update it, of course.

NVIDIA unveiled the GeForce GTX TITAN Z at the GPU Technology Conference last month, and the cards will be for sale soon from various partners. ASUS will be one of the first AIB partners to offer a reference TITAN-Z.
The ASUS GTX TITAN Z pairs two full GK110-based GPUs with 12GB of GDDR5 memory. The graphics card houses a total of 5,760 CUDA cores, 480 texture manipulation units (TMUs), and 96 ROPs. Each GK110 GPU interfaces with 6GB of GDDR5 memory via a 384-bit bus. ASUS is using reference clockspeeds with this card, which means 705 MHz base and up to 876 MHz GPU Boost for the GPUs and 7.0 GHz for the memory.
For comparison, the dual-GPU TITAN Z is effectively two GTX TITAN Black cards on a single PCB. However, the TITAN Black runs at 889 MHz base and up to 980 MHz GPU Boost. A hybrid water cooling solution may have allowed NVIDIA to maintain the clockspeed advantage, but doing so would compromise the only advantage the TITAN Z has over using two (much cheaper) TITAN Blacks in a workstation or server: card density. A small hit in clockspeed will be a manageable sacrifice for the target market, I believe.
The ASUS GTX TITAN Z has a 375W TDP and is powered by two 8-pin PCI-E power connectors. The new flagship dual GPU NVIDIA card has an MSRP of $3,000 and should be available in early May.

Sometimes I feel like this job just keeps getting stranger and stranger. Today is no expection.
After reciving just a tracking number, and no additional information from NVIDIA earlier this week, the mystery package finally arrived today. Upon initial inspection we had no idea what to expect.
When we opened the box, we were greeted by a polystyrene cooler with the logo of Bake Me a Wish, which only served to confuse us more.
As we opened the cooler, and the subsequent box inside of it, things started to make more sense.
Inside the box, we were greeted by a chocolate cake, accompanied by a card from NVIDIA.
As you may remember at this year's GTC Conference, NVIDIA announced that they had ported Valve's Portal to Android and would be releasing it for SHIELD. Today we were greeted with a reminder of that, and the message that we should be able to try it for ourselves.
A teaser from this year's GTC Keynote
While we can't talk about our experiences with Portal just yet, stay tuned to PC Perspective for more coverage of the NVIDIA SHIELD and Portal very soon!

In January of this year, an NVIDIA employee named Philip Scholz died while successfully saving the life of a man who was on the tracks at a Caltrain station in Santa Clara. His family started the Philip Scholz Memorial Foundation to provide scholarship opportunities to needs based youth and promote physical activity, especially baseball. The Foundation has been taking donations directly but now his friends at NVIDIA have raised the bar and are auctioning off an impressive system from Falcon Northwest with the proceeds going to the charity.
Check out the video below and consider putting your money towards a great cause!
We’re now auctioning this amazing system to raise funds for the Philip Scholz Memorial Foundation, honoring an NVIDIA brother who was tragically killed earlier this year when he heroically removed an individual from train tracks and was hit.
The Foundation bearing Phil’s name provides scholarships to needs-based youth and promotes outdoor physical activities involving his favorite pastime, baseball.
This amazing PC uses all the latest technology to deliver absolutely raging performance in a cool, quiet platform.
It starts with the award-winning GeForce GTX Titan Black – the world’s fastest single GPU.
And it includes Intel’s latest Core i7 CPU, the 4770K, running on an ASUS z87 Maximus motherboard loaded with 16GB of GSKILL DDR3 memory. The storage system is based on two 1TB M50 SSDs from Crucial. And it’s all wrapped up in the most impressive chassis available today – the Tiki -- custom designed in NVIDIA green, with a laser cutout window so everyone can see the beast that lives within.
This entire system is fully warranted by Falcon Northwest.
To learn more about Phil and the way he changed those around him, see this story from San Jose Mercury News.
