NVIDIA is up for a rough year

If you caught the podcast last night you would have heard Josh discussing NVIDIA's year end financial conference call, otherwise you will have to wait until the 'cast is posted later this week. Until then you can read SemiAccurate's take on the call here. There is a lot of news about NVIDIA and none of it is good, from wafer yields to chip demand nothing seems to have gone right for them. Attempting to move off of their cursed 40nm line and switching to 28nm, NVIDIA has run into big yield problems as in entire wafers having issues as opposed to just some dies being bad.
Tegra is not doing so well either, with sales of Tegra 2 dropping as we approach the release of Tegra 3, which is getting a lot of bad press. SemiAccurate refers to the chip as bloated in size as well as being downright expensive to make. Combine that with the fact that NVIDIA is lagging on A15 adoption and Samsung and Apple turning their backs on Tegra and it doesn't look good for NVIDIA's mobile plans. The one ray of sunshine is that even combined Samsung and Apple do not account for even half of smartphones on the market, so there is still room for NVIDIA and Tegra to grow.
"Nvidia seems to be so far ahead of the curve that they are experiencing problems that are unique in the industry. In their recent year end financial conference call, there was enough said to draw some very grim conclusions.
Today’s conference call was a near complete validation of all the things SemiAccurate has been saying about Nvidia. Remember when we asked if Nvidia could supply Apple? Anyone notice the part about dumping early 28nm capacity, and the disappearance of 28nm Fermi shrinks? Remember how 28nm was not an issue for Nvidia, even if their product roadmap slips said otherwise. How well does this mesh with the quotes from Jen-Hsun himself on the topic?"

NVIDIA Kepler Graphics Cards Lineup Leak To Web
Subject: Graphics Cards | February 6, 2012 - 06:23 PM | Tim Verry
Tagged: nvidia, kepler, graphics, gpu
Although there were quite a few rumors leading up to AMD's Radeon 7000 series launch, the Internet has been very quiet on the greener side of the graphics market. Finally; however, we have some rumors to share with you on the Nvidia front. As always, take these numbers with more than your average grain of salt.
Specifically, EXP Review managed to uncover two charts that supposedly detail specifics about a range of GeForce 600 series Kepler cards from the number of stream processors to the release date. Needless to say, it's a lot of rumored information to take in all at once.
Anyway, without further adieu, let's dive into the two leaked charts.
| Model | Code Name | Die Size | Core Clock (TBD) MHz | Shader Clock (TBD) GHz | Stream Processors | SM Count | ROPs | Memory Clock (effective) GDDR5 | Bus Width | Memory Bus Width |
| GTX690 | GK110x2 | 550mm2 | ~750 | ~1.5 | 2x1024 | 2x32 | 2x56 | 4.5 GHz | 2x448bit | 2x252GB/s |
| GTX680 | GK110 | 550mm2 | ~850 | ~1.7 | 1024 | 32 | 64 | 5.5 GHz | 512bit | 352GB/s |
| GTX670 | GK110 | 550mm2 | ~850 | ~1.7 | 896 | 28 | 56 | 5 GHz | 448bit | 280GB/s |
| GTX660Ti | GK110 | 550mm2 | ~850 | ~1.7 | 768 | 24 | 48 | 5 GHz | 384bit | 240GB/s |
| GTX660 | GK104 | 290mm2 | ~900 | ~1.8 | 512 | 16 | 32 | 5.8 GHz | 256bit | 186GB/s |
| GTX650Ti | GK104 | 290mm2 | ~850 | ~1.7 | 448 | 14 | 28 | 5.5 GHz | 224bit | 154GB/s |
| GTX650 | GK106 | 155mm2 | ~900 | ~1.8 | 256 | 8 | 24 | 5.5 GHz | 192bit | 132GB/s |
| GTX640 | GK106 | 155mm2 | ~850 | ~1.7 | 192 | 6 | 16 | 5.5 GHz | 128bit | 88GB/s |
From the chart above, we can see the entire lineup of Kepler cards from the NVIDIA GTX 640 to the dual GPU GTX 690. The die size in the higher end GeForce cards is approximately 50% larger than that of the AMD Radeon HD 7970, but not much bigger than that of the GTX 580. If only we knew the TDP of these cards! In the next chart, we see alleged performance comparison versus the AMD competition.
| Model | Bus Interface | Frame Buffer | Transistors (Billion) | Price Point | Release Date | Performance Scale |
| GTX690 | PCI-E 3 x16 | 2x1.75 GB | 2x6.4 | $999 | Q3 2012 | |
| GTX680 | PCI-E 3 x16 | 2 GB | 6.4 | $649 | April 2012 | ~45%>HD7970 |
| GTX670 | PCI-E 3 x16 | 1.75 GB | 6.4 | $499 | April 2012 | ~20%>HD7970 |
| GTX660Ti | PCI-E 3 x16 | 1.5 GB | 6.4 | $399 | Q2/Q3 2012 | ~10%>HD7950 |
| GTX660 | PCI-E 3 x16 | 2 GB | 3.4 | $319 | April 2012 | ~GTX580 |
| GTX650Ti | PCI-E 3 x16 | 1.75 GB | 3.4 | $249 | Q2/Q3 2012 | ~GTX570 |
| GTX650 | PCI-E 3 x16 | 1.5 GB | 1.8 | $179 | May 2012 | ~GTX560 |
| GTX640 | PCI-E 3 x16 | 2 GB | 1.8 | $139 | May 2012 | ~GTX550Ti |
If these numbers hold true, NVIDIA will handily beat the current AMD offerings; however, I would wait for reviews to come out before making any purchasing decisions. One interesting aspect is the amount of GDDR5 memory. It seems that NVIDIA is sticking with 2GB frame buffers (or less) per GPU while AMD has really started upping the RAM. It will be interesting to see how this affects gaming in NVIDIA Surround and/or at high resolutions.
What do you guys think about these numbers, do you think Kepler will live up to the alleged performance scale figures?

3 NV for DCII
The world of video cards is a much changed place over the past few years. Where once we saw only “sticker versions” of cards mass produced by a handful of manufacturers, we are now seeing some really nice differentiation from the major manufacturers. While the first iterations of these new cards are typically mass produced by NVIDIA or AMD and then distributed to their partners for initial sales, these manufacturers are now more consistently getting their own unique versions out to retail in record time. MSI was one of the first to put out their own unique designs, but now we are seeing Asus becoming much more aggressive with products of their own.
The DirectCU II line is Asus’ response to the growing number of original designs from other manufacturers. The easiest way to categorize these designs is that they straddle nicely the very high end and extreme products like the MSI Lightning series and those of the reference design boards with standard cooling. These are unique designs that integrate features and cooling solutions that are well above that of reference cards.
DirectCU II applies primarily to the cooling solutions on these boards. The copper heatipipes in the DirectCU II cooler are in direct contact with the GPU. These heatpipes then are distributed through two separate aluminum fin arrays, each with their own fan. So each card has either a dual slot or triple slot cooling solution with two 80 mm fans that dynamically adjust to the temperature of the chip. The second part of this is branded “Super Alloy Power” in which Asus has upgraded most of the electrical components on the board to match higher specifications. Hi-C caps, proadlizers, polymer caps, and higher quality chokes round out the upgraded components which should translate into more stable overclocked performance and a longer lifespan.
NVIDIA Updates CUDA: Major Release for Science Research
Subject: General Tech, Graphics Cards | January 29, 2012 - 02:53 AM | Scott Michaud
Tagged: nvidia, gpgpu, CUDA
NVIDIA has traditionally been very interested in acquiring room in the high-performance computing for scientific research market. For a lot of functions, having a fast and highly parallel processor saves time and money compared to having a traditional computer crunch away or having to book time with one of the world’s relatively few supercomputers. Despite the raw performance of a GPU, adequate development tools are required to bring the simulation or calculation into a functional program to execute on said GPU. NVIDIA is said to have had a strong lead with their CUDA platform for quite some time; that lead will likely continue with releases the size of this one.
What does a tuned up GPU purr like? Cuda cuda cuda cuda cuda.
The most recent release, CUDA 4.1, has three main features:
- A visual profiler to point out common mistakes and optimizations and to provide instructions which detail how to alter your code to increase your performance
- A new compiler which is based on the LLVM infrastructure, making good on their promise to open the CUDA platform to other architectures -- both software and hardware
- New image and signal processing functions for their NVIDIA Performance Primitives (NPP) library, relieving developers the need to create their own versions or license a proprietary library
The three features, as NVIDIA describes them in their press release, are listed below.
New Visual Profiler - Easiest path to performance optimization
The new Visual Profiler makes it easy for developers at all experience levels to optimize their code for maximum performance. Featuring automated performance analysis and an expert guidance system that delivers step-by-step optimization suggestions, the Visual Profiler identifies application performance bottlenecks and recommends actions, with links to the optimization guides. Using the new Visual Profiler, performance bottlenecks are easily identified and actionable.
LLVM Compiler - Instant 10 percent increase in application performance
LLVM is a widely-used open-source compiler infrastructure featuring a modular design that makes it easy to add support for new programming languages and processor architectures. Using the new LLVM-based CUDA compiler, developers can achieve up to 10 percent additional performance gains on existing GPU-accelerated applications with a simple recompile. In addition, LLVM's modular design allows third-party software tool developers to provide a custom LLVM solution for non-NVIDIA processor architectures, enabling CUDA applications to run across NVIDIA GPUs, as well as those from other vendors.
New Image, Signal Processing Library Functions - "Drop-in" Acceleration with NPP Library
NVIDIA has doubled the size of its NPP library, with the addition of hundreds of new image and signal processing functions. This enables virtually any developer using image or signal processing algorithms to easily gain the benefit of GPU acceleration, with the simple addition of library calls into their application. The updated NPP library can be used for a wide variety of image and signal processing algorithms, ranging from basic filtering to advanced workflows.
Guess what? Overclocked.
The NVIDIA GTX 580 GPU, based on the GF110 Fermi architecture, is old but it isn't forgotten. Released in November of 2010, NVIDIA had held the single GPU performance grown for more than a year before it was usurped by AMD and the Radeon HD 7970 just this month. Still, the GTX 580 is a solid high-end enthusiast graphics card that has wide spread availability and custom designed, overclocked models from numerous vendors making it a viable option.
Gigabyte sent us this overclocked and custom cooled model quite a while ago but we had simply fallen behind with other reviews until just after CES. In today's market the card has a bit of a different role to fill - it surely won't be able to pass up the new AMD Radeon HD 7970 but can it fight the good fight and keep NVIDIA's current lineup of GPUs more competitive until Kepler finally shows himself?
The Gigabyte GTX 580 1.5GB Super Overclock Card
With the age of the GTX 580 designs, Gigabyte had plenty of time to perfect their PCB and cooler design. This model, the Super Overclock (GV-N580SO-15I), comes in well ahead of the standard reference speeds of the GTX 580 but sticks to the same 1.5 GB frame buffer.
The clock speed is set at 855 MHz core and 1025 MHz memory, compared to the 772 MHz core speed and 1002 MHz clock rate of the reference design. That is a very healthy 10% clock rate difference that should equate to nearly that big of a gap in gaming performance where the GPU is the real bottleneck.

FBI Arrests Seven People for Insider Trading of Dell and Nvidia Stock
Subject: General Tech | January 19, 2012 - 06:40 PM | Tim Verry
Tagged: dell, nvidia, insider trading, tech, Law, ethics
There is an important distinction between working within the confines of the law to make the most profit possible and going outside those lines to make a profit while hoping you don't get caught. To drive that point home, the FBI has stated "what distinguishes you from the dozens who have been charged is not that you haven’t been caught; it’s that you haven’t been caught yet." Assistant Director in Charge Janice K. Fedarcyk wrote that when referring to a recent bust of seven individuals accused of insider trading of Dell and Nvidia stock. The arrests, made as part of Operation Perfect Hedge, include seven men who are connected by "friendship or business association."
Thanks to three of the seven men cooperating with the FBI, we know that the men used information about Dell and Nvidia's quarterly earnings prior to any public release of such earnings documents to purchase stock to resell after positive earning documents caused the stock value to increase or to short their stock to avoid losses that would be incurred by lower than expected quarterly earnings causing the stock price to drop. On the Dell side of things, two employees in the know provided quarterly earnings numbers to various hedge funds. The first employee, Sandy Goyal, is charged with providing a hedge fund with Q1 earning results for 2008 in exchange for $175,000. The hedge fund then used that insider information to make $3.8 million dollars. Another (former) Dell employee, Jesse Tortora furnished three hedge funds with quarterly earnings numbers who each then made $4 million on Q1 information and $53 million on the Q2 information, $1 million in profit, and the final Hedge fund avoided #78,000 in losses by selling stock before the inevitable price drop thanks to knowing the negative earning numbers before hand.
Finally, Danny kuo knew someone who worked at Nvidia and provided information to the other members of the insider trading group.
Let this be a lesson to those business folks that slept through ethics classes, stay away from insider trading, especially when you are paid for the information as you are just asking to get caught. (Cue the "Cops" theme song). Normally we don't cover this kind of news; however, I thought it applicable since it involves Dell and Nvidia. Also, speaking of quarterly earnings, Josh will have all the details from today's Intel Earnings Call up soon.
