Okay so the pun was a little obvious, but NVIDIA has just announced the specifications and name for the development kit used to develop for their ARM-based GPU computing platform. The development kit will provide a method to build and test applications on a platform similar to what will be found in the Barcelona Supercomputing Centre’s upcoming GPU supercomputer until you are ready to deploy the finished application with real data on the real machine. Such is the life of a development units.

Carma: What goes around, comes around... right Intel?

The development kit is quite modest in its specifications:

  • Tegra3 ARM A9 CPU
  • Quadro 1000M GPU (96 CUDA Cores)
  • 2GB system RAM, 2GB GPU RAM
  • 4x PCIe Gen1 CPU to GPU link
  • 1000Base-T networking support
  • SATA, HDMI, DisplayPort, USB.
 
While the specifications are somewhere between a high-end tablet and a modest workstation, the real story is the continued progress by NVIDIA into the High Performance Computing (HPC) market. NVIDIA seems to be certain that they are able to (ARM-)wrestle more market share from Intel and other players such as IBM on the high performance front. Many would probably speculate about NVIDIA’s crushing in towards the home market from both ends, but I expect that creating a compelling ARM product for a desktop PC will never be the problem for NVIDIA: it is a lack of anything compelling to run on it these days for a desktop user.

Introduction

As the neighborhoods are adorned with lights and reindeer decorations, and the airwaves are ringing with Christmas carols, one realizes that it is that time of year again!  Although December arrived much faster than any of us at PC Perspective expected, there is no doubt that time to purchase gifts is running short and this year is almost over.

In keeping with the holiday spirit, the PC Perspective team got into a discussion about items and services that we would want for Christmas and that we felt would make really great gifts for our loved ones.  And thus the PC Perspective Holiday Gift Guide 2011 was born!

It is far too common for your coffee table to have several so called universal remotes on it, to control the variety of electronic equipment which makes up your entertainment center.  Each one will have a device that it works best with, either because of the presence of certain buttons or even simply not having a working control code.  Tech Reviews has a possible solution for you and one that doesn't even cost all that much. The One For All Smart Control is designed to work with TV, STB, DVD, AMP, MP3 and Media devices and the best part about it is that some commands can be given using motions.  Soon screaming and waving your remote at your TV will actually accomplish something.

"We’ve all seen universal remote controls for TVs, but the One For All Smart Control takes things to a completely different level. The Smart Control provides the ability to control your devices with just a simple flick, or tap, of the remote control. Retailing at only £17.50, the One For All Smart Control is an absolute bargain considering you’re receiving quite a few features. Let’s take a closer look…"

Radeon HD7970 specs leaked. 3.5 Teraflops, 3GB vRAM

Subject: General Tech, Graphics Cards | December 16, 2011 - 04:45 PM |
Tagged: Radeon HD 7000, leak, amd

Update: 5:35, added a few points.

If the convincing-looking leaked slides are to be believed, the upcoming AMD Radeon HD 7970 card is now naked before us with all its measurements laid to bare. While there still is nothing official as the embargo is not up yet, rest assured that at some point the full story will flood to the surface. What can be said is that if this slide is true, the 7970 looks to be a real beast of a card.

The supposed reference specifications of the 7970… or are they?

(Image obviously from OBR-Hardware)

As you can tell from the heavily watermarked slide, AMD claims 3.5 TFLOPs of computing power from their 2048 stream processing units clocked at 925 MHz. Contrast this against the AMD’s assertion of 2.7 TFLOPs from the Radeon 6970’s 1536 stream processors and a core clock of 880MHz; while it is not an apples-to-apples comparison, it is a healthy buff to AMD’s portfolio. Also relevant, is a more recent slide claiming much-increased performance during tesselation which NVIDIA typically has maintained a healthy lead over AMD with.

Possibly the most major point from the table is the power consumption: less than 3 Watts during idle. To give a bit of... pc perspective...: HardOCP measured the idle power consumption of the 6970 to be 24 Watts and the NVIDIA GTX 580 at 41 Watts. We are talking about an 88% decrease in idle power draw compared to AMD’s last generation’s single GPU powerhouse. It makes me wonder: how will this affect mobility graphics? According to OBR-Hardware, their slide is somewhat out-of-date; the expected peak is 200W give or take for the card on load, though I am sure that will vary depending on which brand of card you purchase.

Amazon Selling Millions of Kindle Fire Tablets

Tagged: kindle, tablet, kindle fire, ereader, sales

Although Amazon’s recent Kindle Fire eReader and tablet arrived to mixed reviews due to performance issues and privacy concerns, a great number of consumers (mainly less demanding relatives of tech enthusiasts from my experience) are buying them and enjoying them. Of personal experience, my significant other has yet to let it out of her sight for me to have time to test it out for example.

Therefore, I assumed the Kindle Fire was selling well. The sales seem to be much better than I expected; however, if these numbers by CNet turn out to be true. According to Amazon, the Kindle Fire has been the “bestselling, most gifted, and most wished for product” on Amazon.com ever since the tablet’s November 15th release.

P1050244.JPG

Cnet further talked with the CEO of eDataSource Carter Nicholas who stated the Amazon statement on the Fire’s popularity was likely true. The market research firm has compiled data that shows Amazon sold 45,000 Kindle Fire tablets in one day last month alone, and Nicholas predicts increased sales over the holiday seasons. Approximately 850,000 Kindle Fires have been sold through Amazon.com’s website. Further, Isupply estimates that Amazon will ship 3.9 million Kindle Fire eReaders between October (pre-orders) and the end of December. While 850,000 Fire’s have been sold from the website, by including all channel partners and brick and mortar stores, it is estimated that Amazon has sold upwards of 2 million Fire tablets already. More information can be had here.

Because of the price, the Kindle Fire is selling like it is some kind of fire powered hotcake sale. Have you had a chance to play around with the Amazon tablet yet, and if so what are your thoughts on the device? Do you think the company will sell enough devices to give Apple a run for it’s money?

We saw a BF3 branded gaming peripheral kit not long after the arrival of the game and you can get your hands on a Diablo 3 branded kit already, even though we are still awaiting the release of that game.  Now Razer offers some love to fans of Star Wars: The Old Republic with a new mousepad, mouse and headset kit all bearing a familiar logo.  The mouse is based on the Naga and has a 5600dpi sensor, 17 programmable buttons and both wired and wireless capabilities.  Most important the LEDs can switch between red or blue (well, 16 million colours total) as well as changing the logo to properly advertise the side you have chosen.  The headset uses 50mm drivers and also sports changeable logos and LED colours, though the mousepad lacks that ability.  Along with the pack, Hardware Heaven points out that you get a colour change crystal for use in game to change the colour of your blaster bolts and lightsaber blade.

"Every big game release can be enhanced by a set of quality devices which tie in with the overall feel of the franchise and that is exactly what Razer aim to deliver with their The Old Republic gaming gear. We have the mouse, headset and mouse mat on our test bench today for a detailed look at what they offer for The Old Republic gamer."

Can your smartphone deal with 100,000 triangles per frame? Find out with Rightware OpenGL ES Halti

Subject: General Tech | December 15, 2011 - 12:25 PM |
Tagged: ES Halti, opengl, Basemark ES 2.0, rightware

The mobile reviews at PC Perspective tend to use SunSpider and Vellamo we also use a RightWare product called BrowserMark to test the responsiveness of smart phones and tablets.  RightWare now has a new tool for reviewers and those who tweak their phones, Basemark Halti which tests OpenGL performance.  This is of huge importance for those who want to have high quality gaming performance on their phones.  The first benchmark is called Rush and is reminiscent of Mirror's Edge, which is quite on purpose as the benchmark is intended to replicate PC quality character rendering.   The second involves a car racing around a track, a common type of gaming on a phone that contains an accelerometer.  Again, this is intended to push the ability of your phone as far as it can go.  AnandTech doesn't have the benchmarking software yet but you can bet it will be in their reviews for 2012.

AAT_Media1.jpg

"GPU benchmarking on the smartphone side of things is continuing to heat up, and today RightWare, maker of both BrowserMark and the very popular Basemark ES 2.0 (which are regular fixations in our smartphone reviews), has announced its OpenGL ES Halti benchmark, named Basemark Halti. Basemark Halti is slated to launch in 2012 for testing OpenGL ES Halti on devices coming in the near future."

CUDA been done sooner! NVIDIA open sources CUDA platform

Subject: General Tech, Graphics Cards, Processors | December 15, 2011 - 04:03 AM |
Tagged: CUDA

NVIDIA lays as the current front-runner for the “Last Year’s Best Decision, This Year” award. You may remember our coverage last June of the AMD Fusion Developer Summit; industry members such as ARM, Microsoft, and of course AMD discussed the potential of utilizing specialized processors and developing on open platforms such as OpenCL and Microsoft’s announced C++ AMP. Do you know what would have been an amazing announcement for AFDS to stomp OpenCL and C++ AMP? That NVIDIA would open up CUDA. Know what announcement missed that bus by a whole half a year? NVIDIA will open up CUDA.

GPGPU-Trail.png

Your platform pooh-pooh? Bear a CUDA.

While I just harassed NVIDIA for their timing, it might not be too late. CUDA is still a powerhouse of a GPGPU platform with substantial software support from absolute mammoth software packages such as Adobe Creative Suite to smaller projects like KGPU. With the open sourcing of the CUDA compiler, NVIDIA is also permitting manufacturers like AMD and even Intel to support CUDA with their GPUs, x86 CPUs, and other processing units. While I am excited at this outcome, I am still somewhat confused about NVIDIA’s timing: they are just a little late to open up and crush the market, and they seem quite abrupt if they originally intended CUDA to survive as a forever-proprietary computing platform.

Google Extending Free Domestic Gmail Calling Another Year

Subject: General Tech | December 15, 2011 - 01:09 AM |
Tagged: voip, google, gmail

Just in time for the holidays, Google is extending the free domestic calling via the Gmail VOIP service another year. Last year the company extended the free computer to telephone VOIP service another year and now they are doing it again. “This is our way of helping you connect with friends and family across the country,” states their recent blog entry.

call_phones.png

In case you haven’t used the Gmail VOIP service yet, it is similar to the computer to computer and computer to cellphone (or land line) calling that you can do in Google Voice, only this is integrated into Gmail. It does require a small browser plug-in; however, it is worth it. Accessing it by clicking on the “Call a phone” link in the Gmail sidebar (in the chat/SMS section), you are able to put that headset to work by calling anyone in the US and Canada for free. I’ve used it a couple of times and found it to be rather handy for quick conversations while at my computer. Have you tried it out yet, and did you find it useful?

Holy failed patch Batman!

Tagged: gaming, dx11, batman arkham city

Batman makes it three for three as far as failed patches go for the current major releases.  Battlefield's patch was probably the best of the three, Skyrim being the worst with Batman's simply failing to deliver what it promised ... improved DX11 performance.  [H]ard|OCP recently reviewed the original game and now has published the results of their testing with the new patch.  The good news is that most of the stuttering and crashes have been fixed, leaving only significantly lower performance when in DX11 mode compared to DX9.  Originally you could expect a 50% reduction in fps when enabling DX11 and NVIDIA users can expect the same results at this point, AMD users will see their performance reduced by even more than pre-patch though the game its self should be more stable.  If you want to run Batman Arkham Asylum at high resolution, you better have two GPUs.

"Days after our Batman: Arkham City Gameplay Performance and IQ review was published, the game was patched. The patch was ostensibly reported to fix DirectX 11 performance problems plaguing the game, but does it really do the trick? Where do our DX11 video cards stand now?"
