NVIDIA's Tegra 4i System on a Chip includes a software defined radio that works as a LTE modem. This i500 LTE modem uses general purpose deep execution processors (DXP) and is as much as 40% smaller than a hardware LTE modem according to the company.
At Mobile World Congress earlier this year, the modem was able to reach 100Mbps throughput. After a recent software update, the Tegra 4i SoC in NVIDIA's Pheonix reference platform achieved 150Mbps throughput in a demo at CITA 2013 in Los Angeles this week.
The reference phone was connected to a test network during the demo rather than a live cellular network. The cellular network test equiptment showed the Pheonix platform was connected at the full 150Mbps link speed. In addition to this, NVIDIA showed the Tegra 4i-powered Pheonix phone connected to a live AT&T LTE network streaming video and making voice calls.
The interesting bit about the i500 modem in the Tegra 4i is its software defined nature. NVIDIA was able to upgrade the modem's capabilites through software rather than needing to redesign the hardware. This would be a big plus to consumers as they would be able to take advantage of the faster network speeds as they become available without needing to replace their phones. NVIDIA did note that in addition to the LTE Cat 4 support, the i500 is also backwards compatible with LTE Cat 3, 3G, and 2G networks. I'm interested to see what the power consumption of thei500 is like compared to LTE modems implemented in specialized hardware. The i500 is smaller and more flexible, but SDR can use more power due to its general purpose hardware units.

Introduction and Design
While Lenovo hasn’t historically been known for its gaming PCs, it’s poised to make quite a splash with the latest entry in its IdeaPad line. Owing little to the company’s business-oriented roots, the Y500 aims to be all power—moreso than any other laptop from the manufacturer to date—tactfully squeezed into a price tag that would normally be unattainable given the promised performance. But can it succeed?
Our Y500 review unit can be had for $1,249 at Newegg and other retailers, or for as low as $1,180 at Best Buy. Lenovo also sells customizable models, though the price is generally higher. Here’s the full list of specifications:
The configurations offered by Lenovo range in price fairly widely, from as low as $849 for a model sporting 8 GB of RAM with a single GT 650M with 2 GB GDDR5. The best value is certainly this configuration that we received, however.
What’s so special about it? Well, apart from the obvious (powerful quad-core CPU and 16 GB RAM), this laptop actually includes two NVIDIA GeForce GT 650M GPUs (both with 2 GB GDDR5) configured in SLI. Seeing as it’s just a 15.6-inch model, how does it manage to do that? By way of a clever compromise: the exchange of the usual optical drive for an Ultrabay, something normally only seen in Lenovo’s ThinkPad line of laptops. So I guess the Y500 does owe a little bit of its success to its business-grade brethren after all.
In our review unit (and in the particular configuration noted above), this Ultrabay comes prepopulated with the second GT 650M, equipped with its own heatsink/fan and all. The addition of this GPU effectively launches the Y500 into high-end gaming laptop territory—at least on the spec sheet. Other options for the Ultrabay also exist (sold separately), including a DVD burner and a second hard drive. The bay is easily removable via a switch on the back of the PC (see below).

Tagged: VIA, Q1 2013, nvidia, jpr, Intel, gpu market share, amd
Market analytics firm Jon Peddie Research recently released estimated market share and GPU shipment numbers from Q1 2013. The report includes information on AMD, NVIDIA, Intel, and Via and covered IGPs, processor graphics, and discrete GPUs included in desktop and mobile systems powered by X86 hardware. The report includes x86 tablets but otherwise does not factor in GPUs used in ARM devices like NVIDIA's Tegra chips. Year over Year, the PC market is down 12.6% and the GPU market declined by 12.9%. It is not all bad news for the PC market and discrete GPU makers, however. GPUs through 2016 are expected to exhibit a compound annual growth rate (CAGR) of 2.6% with as many as 394 million discrete GPUs shipped in 2016 alone.
In Q1 2013, the PC market is down 13.7% versus last quarter (Q4 2012) but the GPU market only declined 3.2%. This discrepency is explained as the result of people adding multiple GPUs to a single PC system, including adding a single discrete card to a system that already has processor graphics or an APU. By the end of Q1 2013, Intel holds 61.8% market share followed by AMD in second place with 20.2% and NVIDIA with 18%. Notably VIA is out of the game with 0.0% market share.
In terms of GPU shipments, NVIDIA had a relatively good first quarter of this year with an increase of 7.6% for notebook GPUs and desktop GPU shipments that remained flat. Overall, NVIDIA saw an increase in PC graphics shipments of 3.6%. On the other hand, x86 CPU giant Intel saw desktop and notebook GPUs slip by 3% and 6.3% respectively. Overall, that amounts to PC graphics shipments that fell by 5.3%. In between NVIDIA and Intel, AMD moved 30% more desktop chips (including APUs) versus Q4 2012. Meanwhile, Notebook chips (including APUs) fell by 7.3%. AMD's overall PC graphics shipments fell by 0.3%.
In all, this is decent news for the PC market as it shows that there is still interest in desktop GPUs. The PC market itself is declining and taking the GPU market with it, but it is far from the death of the desktop PC. It is interesting that NVIDIA (which announced Q1'13 revenue of $954.7 million) managed to push more chips while AMD and Intel were on the decline since NVIDIA doesn't have a x86 CPU with integrated graphics. I'm looking forward to seeing where NVIDIA stands as far as the mobile GPU market which does include ARM-powered products.

Solid information about the NVIDIA Shield (no longer called Project Shield) is finally becoming available with a blog post written up today on NVIDIA's website. The company will begin accepting pre-orders from users that have previously signed up for the Shield mailing list while the rest of you will have to wait until May 20th to plop down your money.
The cost? $349. Newegg, Gamestop, Micro Center and Canada Computer will carry it.
If you want to sign up for official June release schedule of the Tegra 4 powered mobile Android gaming device, you'll have to head over to shield.nvidia.com.
NVIDIA does point out in the blog that the PC game streaming feature that I truly believe is the one thing that makes Shield a compelling gaming device, will be launching as BETA feature.
And GeForce game streaming, launching as a beta feature, will give SHIELD the power to access your NVIDIA GeForce GTX GPU-powered computer from the comfort of your couch. We’re working on streaming your favorite PC games to SHIELD, including great titles from Steam.
High level features of the device, for those of you that are unaware, include:
- Tegra 4 – The world’s fastest mobile processor delivers rich graphics and unbeatable performance thanks to 72 GPU cores, four CPU cores and 2GB of RAM
- Console-grade controller – Precise control thanks to dual analog joysticks, a full-sized D-Pad, left and right analog triggers, full-sized bumpers and A/B/X/Y buttons
- Multi-touch display – 5-inch, 720p retinal multi-touch display for high-fidelity visuals
- Integrated speakers – Custom, bass reflex, tuned port audio system – we think this is SHIELD’s sleeper feature
- Wi-Fi – 802.11n 2X2 MIMO game-speed Wi-Fi for seamless game streaming
- Pure Android – Latest Android Jelly Bean operating system from Google, for access to Android games and apps
- There’s more – We put into SHIELD everything we would want in a premium mobile gaming device: 16 GB memory, GPS, Bluetooth 3.0, a mini-HDMI output, micro-USB 2.0, a microSD storage slot, a 3.5-mm stereo headphone jack. See the full spec sheet, here.
We took a look at the NVIDIA Shield device at CES this year and posted a video of our experiences, so check it out below.
NVIDIA has also posted a separate blog that talks about some of the upcoming Android games that will highlight the power of the Tegra 4 mobile processor including Broken Age and Costume Quest from Double Fine, Chuck's Challenge from Niffler and more.
I think many people at NVIDIA as well as in the media are very curious to see what the reaction of Shield will actully be upon its release. I am very excited to test it out in real-world, long term usage models but I definitely have doubts about the market's desire for another mobile gaming platform.
Leave me your thoughts in the comments below!!

If you have been wondering how the two flagship GPUs fare in a battle royal of pure frame rate you can satisfy your curiousity at [H]ard|OCP. They have tested both NVIDIA's TITAN and the finally released HD7990 in one of their latest reviews. Both cards were force to push out pixels at 5760x1200 and for the most part tied, which makes sense as they both cost $1000. The real winner was Crossfired HD 7970's which kept up with the big guns but cost $200 less to purcahse.
If that isn't extreme enough for you, they also overclocked the TITAN in a seperate review.
"We follow-up with a look at how the $999 GeForce GTX TITAN compares to the new $999 AMD Radeon HD 7990 video card. What makes this is unique is that the GeForce GTX TITAN is a single-GPU running three displays in NV Surround compared to the same priced dual-GPU CrossFire on a card Radeon HD 7990 in Eyefinity."

NVIDIA seems to have completely ignored the economic downturn that has affected so many tech companies and posted gains in both revenue and profit for Q1 2013. The entire PC market may have shrunk by 10% but NVIDIA's profits were up 16.7% compared to 12 months ago, though when looking at GPU sales alone they did see about a 5% decline. Now that NVIDIA has branched out into mobility and HPC however, their total sales are up by 3%. The Register postulates that part of the reason their sales did not decline as much as other manufacturers is their focus on high end GPUs which are immune to the erosion being caused by sales of mobile devices such as tablets. Get the whole set of numbers here.
"In the first quarter of fiscal 2014 ended on April 28, Nvidia's overall sales rose by 3.2 per cent to $954.7m. Big Green was able pull $77.9m to the bottom line, up 16.7 per cent compared to the year-ago period – even while investing in a substantial bump-up in research and development costs – thanks to a shift to higher margin products in both the discrete graphics and Tesla GPU coprocessor lines."

After the initial announcement at CES in January, NVIDIA has been trying hard to keep excitement and interest about Project Shield going. The upcoming Tegra 4-powered mobile Android-based gaming machine will be launched sometime in the summer; both Computex and E3 would make perfect timing.
NVIDIA passed us a photo of the mold for the casing of Project Shield and though you don't really get any awesome new information out of it, I thought I would share.
The photo you see below shows the production mold that's used to craft the ergonomic casing that houses Project SHIELD's high-powered components: Tegra 4, 5-inch 720p HD retinal touchscreen, Stereo Bass Reflex Speakers, WiFi, accelerometer, gyro, a massive battery, and more.
To create the casing, we inject a polycarbonate material into the RHCM (Rapid Heat Cycle Molding) tool at 10,800 PSI and 300 degrees Celsius. We use a polycarbonate mixture comprised of 90% Sabic 500ECR-739 PC and 10% glass. This material and injection molding process ensures a sturdy yet lightweight casing that will deliver hours of gaming with no fatigue.
In case you are behind on what Project Shield is, you should check out the hands-on video we made during our time with the device last January.
What do you think...are you excited about the launch of this device? Do any of its features really make you want to buy it once available?

Tagged: tegra 4, nvidia, grid, financial results
NVIDIA has released the results of its first fiscal quarter of 2014. Overall, NVIDIA had a positive first quarter with total revenue of $954.7 million and a net income of $77.9 million. During Q1 2014 the company announced its Grid VCA for enterprise customers and Tegra 4 and Tegra 4i for the mobile market. NVIDIA’s shareholders saw an Earnings Per Share (EPS) of 13 cents, which is up 30% versus the same quarter last year. Interestingly, NVIDIA has announced that it will be returning $1 billion to shareholders through increased dividends and buying back shares.
Q1 2014 is an interesting quarter, as it is up year over year, but down significantly versus the previous quarter (Q4’13). NVIDIA’s Q1’14 revenue of 954.7 million is up YOY 32% from $924.9 million in Q1’13, but down 13.7% from $1.1 billion in the previous quarter. The dip is likely attributable to the fact that its Q1’14 is the quarter after the holiday rush at the end of Q4. Considering it is still up versus last year, the dip versus last quarter shouldn’t be taken as a bad sign. Net income follows a similar pattern, with net income down 53.2% versus last quarter’s $174 million, but up 29% YOY (Q1’13 net income was $60.9 million).
The financial results seem to indicate that NVIDIA is continuing to grow and remain profitable. According to NVIDIA, the company expects to see operating expenses and revenue increase in Q2’14 to $448 million in and approximately $975 million respectively. Further, NVIDIA expects growth to continue throughout 2014 as it launches new Tegra 4(i) SoCs and expands its server/business offerings with its GRID technologies.
You can find NVIDIA's full financial report on the company's website.

Update: Did you miss the live stream? Watch the on-demand replay below and learn all about the Frame Rating system, FCAT, input latency and more!!
I know, based solely on the amount of traffic and forum discussion, that our readers have really adopted and accepted our Frame Rating graphics testing methodology. Based on direct capture of GPU output via an external system and a high end capture card, our new systems have helped users see GPU performance a in more "real-world" light that previous benchmarks would not allow.
I also know that there are lots of questions about the process, the technology and the results we have shown. In order to try and address these questions and to facilitate new ideas from the community, we are hosting a PC Perspective Live Stream on Thursday afternoon.
Joining me will be NVIDIA's Tom Petersen, a favorite of the community, to talk about NVIDIA's stance on FCAT and Frame Rating, as well as just talk about the science of animation and input.
The primary part of this live stream will be about education - not about bashing one particular product line or talking up another. And part of that education is your ability to interact with us live, ask questions and give feedback. During the stream we'll be monitoring the chat room embedded on http://pcper.com/live and I'll be watching my Twitter feed for questions from the audience. The easiest way to get your question addressed though will be to leave a comment or inquiry here in this post below. It doesn't require registration and this will allow us to think about the questions before hand, giving it a better chance of being answered during the stream.
Frame Rating and FCAT Live Stream
11am PT / 2pm ET - May 9th
So, stop by at 2pm ET on Thursday, May 9th to discuss the future of graphics performance and benchmarking!
