Quick glance at the new MBP

The newly released retina-screen MacBook Pro has been an interesting product to me since it was first announced. I have long been a proponent of higher resolution screens for PCs, hoping for the lower cost screens that we are just now finding in the Korean 27-in screen market (like the Achieva Shimian we recently reviewed). When Apple announced a 15-in notebook with a screen resolution of 2880x1800, my hopes were raised that other vendors would take note and duplicate the idea – thereby lowering costs and increasing visual quality for users across the board.

While I didn’t have enough time with the retina MacBook Pro to give it a full review, I did spend an afternoon with one that had Windows 7 installed. After getting some benchmarks and games installed I thought I would report back to our readers with my thoughts and initial impressions on the laptop from a PC perspective.

The hardware inside the new retina MacBook Pro includes an Ivy Bridge Core i7-3720QM processor, NVIDIA GeForce GT 650M discrete GPU, 512GB Apple-branded solid state drive, USB 3.0, Thunderbolt and of course that impressive 2880x1800 screen.

We have seen and reviewed NVIDIA’s high-end Kepler graphics cards, but the company’s mid-range line has been even harder to find than the GTX 680 was a couple months ago. That may be about to change though, as recent rumors suggest that the company is preparing at least three mid-range graphics cards for public release.

geforce-gt-640-3qtr.png

The current GT 640. Expect the refresh to look very similar.

The cheapest rumored card is a refresh of the existing GeForce GT 640. The refresh is slated for an August 2012 release and it takes the existing GK107 GPU with 384 CUDA cores and pairs it with GDDR5 memory instead of the currently used GDDR3. Videocardz predicts that the move to GDDR5 will bump the price up to a bit over $100.

The next card up will reportedly cost around $150 and will be released in August. The GeForce GT 650 Ti will allegedly be based around the GK106 GPU with 960 CUDA cores enabled. It will likely be paired with up to 2GB of GDDR5 memory and a 192-bit memory interface. This card will likely be the high-end HTPC and/or very entry level gaming card on the NVIDIA side.

However, for those serious about wanting to get into gaming, they should probably spend a bit more on the GPU and get at least the GTX 660. This rumored card is using a GK106 GPU with 1152 CUDA cores enabled and an alleged 1.5GB of GDDR5 memory with a 192-bit interface. As far as pricing, it will be positioned between the GT 650 Ti and the GeForce GTX 670 – somewhere in the $200-300 range.

Interestingly, if rumors turn out to be true, there may be yet another new graphics card that would fill the performance (and price) void between the GTX 660 and GTX 670: the GeForce GTX 660 Ti. Allegedly, the GTX 660 Ti would be very close to the GTX 670 as far as specifications are concerned. Both cards are based on the GK104 Kepler GPU (which we recently reviewed) and would have 1344 CUDA cores enabled. Where the two differ in the predicted specifications is memory. While the GeForce GTX 670 has either 2GB or 4GB of GDDR5 memory on a 256-bit interface, the GTX 660 Ti will have 1.5GB or 3GB of GDDR5 memory with a 192-bit interface. This card is also predicted to be released in August with the above mentioned NVIDIA GPUs. You can expect this card to be priced in the $300 to $400 dollar range, with an emphasis on the former for reference designs with 1.5GB of memory.

All these rumored cards should really help NVIDIA to flesh out its Kepler lineup and take on AMD on all fronts. These cards (assuming the rumors hold true, of course) should also be much easier to find and get a hold of since they are probably using binned chips that could not be sold as a GTX 670 or GTX 680 which were difficult to find in stock at launch.

What do you think about these rumors, do they sound plausible? Have you been holding off on Kepler until cheaper cards are released? Let us know in the comments below. You can find more information on the rumored graphics cards here.

AMD and NVIDIA are sticking with TSMC

Tagged: TSMC, Samsung, amd, nvidia, 28nm, rumour

All of the speculation about the problems TSMC has had with their 28nm process and the possible issues they might have producing enough wafers to meet their clients demands.  Today we hear from DigiTimes that Qualcomm is going to switch to Samsung, possibly because TSMC was focusing on AMD and NVIDIA, but this is pure speculation at the moment.  What seems more reliable is that GPU vendors are stating that both AMD and NVIDIA are sticking with TSMC which makes a lot of sense, even if TSMC has problems delivering it is a better alternative than AMD or NVIDIA redesigning their graphics processors to be compatible with Samsung's process.  The story also mentions that in 2013 Brazos 2.0 and Hondo will be moved to a 28nm design, again likely sourced at TSMC.

"While Qualcomm has reportedly switched foundry orders for its 28nm-based Snapdragon S4 processors from Taiwan Semiconductor Manufacturing Company (TSMC) to Samsung Electronics because TSMC's 28nm capacity has failed to meet its needs, Nvidia and AMD may not follow suit, according to graphics card makers.

TSMC has the upper hand over Samsung in 28nm technology, yield rate and price and therefore changing foundry partnership involves high risks, the sources said. In addition, Nvidia is expected to consider Samsung's ARM-based processors in competition with its Tegra 3 processors, the sources indicated."

Introduction and Design

lenovo1.jpg

In the wilds of the laptop market, nestled between the hordes of 15.6” mainstream laptops and the slim ultraportables, there is an odd breed. The 14” multimedia laptop. Even describing them as such is limiting because each model seems to offer its own take on the concept. Some are nearly as thin and light as laptops with much smaller displays while others are bulky powerhouses hidden behind a façade of portability.

Lenovo has long been a proponent of the 14-incher in actions if not words. IdeaPads of this size have also been common, usually gracing Lenovo’s website as a smaller alternative to a 15.6” laptop with a similar model name.

As a result, absolutely no one was shocked when Lenovo announced the IdeaPad Y480. It’s exactly the kind of product most consumers end up buying and exactly the kind of product tech journalists don’t care to talk about. 

So what’s powering this new mid-size laptop? Let’s have a look.

New NVIDIA 304.79 Beta Drivers Add TXAA and Bug Fixes

Subject: Graphics Cards | July 3, 2012 - 05:17 PM |
Tagged: txaa, nvidia, graphics drivers, gpu, drivers, bug fixes

NVIDIA has made the latest version of its beta graphics card drivers available for download. With the new version 304.79 beta drivers comes TXAA support, numerous bug fixes, and the first unified Windows 8 and Windows 7 release.

nvidia_gtx680.jpg

We covered TXAA, or temporal anti-aliasing, in our NVIDIA GTX 680 2GB review. The new 304.79 drivers enable support for it in The Secret World MMORPG – following a game update. TXAA will come in two levels with TXAA 2 having quality greater than 8x MSAA, especially with in-game objects like chain link fences. The issue with TXAA adoption is that it must be implemented in the game engine, and cannot simply be added on after the fact via the NVIDIA control panel. Also, it is a feature that is exclusive to the company’s 600-series Kepler graphics cards.

txaa07.jpg

There are a few other games that have claimed support for TXAA, but gamers will have to wait for a future update to take advantage of it.

The beta drivers are the first graphics drivers to be a unified release with support for both desktops and laptops running Windows XP, Vista, 7 and 8. Further, the company has updated its SLI profiles to support End of Nations, Nexuiz, Tom Clancy’s Ghost Recon Future Soldier, Tornado Force, and Tribes: Ascend. The release also addresses a number of bugs. Some of the larger bug fixes include a fix for an issue that caused the PC to reboot instead of shut down, an issue that caused a black screen after driver installation, and a fix for flickering mouse cursors when hardware cursor is enabled in certain games.

You can find the complete list of bug fixes in the release notes, and you can grab the latest beta drivers from the NVIDIA website.

Colorful Shows Off Massive Passively Cooled NVIDIA GTX 680

Subject: Graphics Cards | July 2, 2012 - 06:53 PM |
Tagged: passive cooling, nvidia, kepler, gtx 680, gpu

Chinese graphics card manufacturer Colorful recently showed off a massive NVIDIA GTX 680 GPU. Massive may even be an understatement, as this card uses not one, but two heatsinks – and more heatpipes that Josh can shake a GPU at – to passively cool the fastest single GPU graphics card that NVIDIA has.

Colorful-680-1.jpg

While there is no word on pricing, availability, or clock speeds, the iGAME NVIDIA GTX 680 is a silent GPU that is going to need a seriously large case. One heatsink attaches as you would expect, right over the GPU, GDDR5 memory, and VRMs. It uses 140 aluminum fins and seven heatpipes traveling the length of the PCB to distribute heat.

Colorful-680-6.jpg

From there, six copper heatpipes transfer heat to a second heatsink with another 140 fins and seven heatpipes(!). This second heatsink appears to float over the top of the card, supported by the six heatpipes. The heatsink and PCB are black, with a blue piece covering the two heatsinks that features the iGame and NVIDIA GTX 680 logos. The back of the card features a single DVI port, a DisplayPort, and a full-size HDMI port.

For the PC gamer that values silent performance with the least compromises possible, this card is looking like the perfect solution – assuming it comes to market, of course. If you are interested in seeing more photos of this passively cooled GTX 680 graphics card, check out the EXPReview story.

GeForce 302.82 Driver for Win8

Subject: Graphics Cards | June 27, 2012 - 03:52 PM |
Tagged: win8, whql, nvidia, geforce, driver

If you are running Windows 8 and an NVIDIA graphics card on a desktop machine then you should head on over to NVIDIA to grab the WHQL certified GeForce 302.82 for 32-bit and 64-bit versions of the pre-release OS.  If you are on a laptop then NVIDIA suggests you should continue to use the 302.80 drivers for the moment. 

twimtbp.png

You will see a new NVIDIA Control Panel page that allows you to set up stereoscopic 3D for 3D Vision.  The drawbacks are few, the driver will request a reboot in order to finish the installation, which you should do whether you are asked or not, and there is an issue for users of the GT520 who enable FXAA via the NVIDIA control panel but other than those two addendum, NVIDIA posted no other known issues.  As it is a WHQL version, you can expect it to be stable and to be around for a bit as the release date of Win8 slowly approaches.

NVIDIA Responds to Linus Torvalds’ Rant

Subject: General Tech | June 21, 2012 - 01:35 PM |
Tagged: rant, optimus, open source, nvidia, linux, linus, drivers

Last week, the founder of Linux – Linus Torvalds – gave a speech at the Aalto Center for Entrepreneurship. The aspect that most people picked up on was a certain disparaging statement towards NVIDIA. Since then, the video has spread rapidly around the Internet with critics for and against the statement. Linus does not believe that NVIDIA is easy to work with regarding Linux support, in short. NVIDIA PR recently responded to his statement in stating that the company is in fact heavily involved with Linux development, albeit mobile kernels.

nvidia-2.jpg

NVIDIA stated in its PR release that supporting Linux is important to the company and they understand how important a positive Linux experience using NVIDIA hardware is. I don’t think anyone is surprised by that statement, but that was not all they said. The company stated that they are big supporters of the ARM Linux kernel with a claimed second most total lines changed and fourth highest number of changesets in the kernel.

The company uses proprietary drivers, but it does support GeForce, Quadro, and Tesla graphics cards under the Linux operating system. By using a common, proprietary driver, NVIDIA claims same-day support for new graphics cards and OpenGL versions for both Windows and Linux operating systems.

Linus’ rant started when an audience member asked about Optimus support under Linux. On that front, NVIDIA did not have a direct answer – only that when it launched laptops with Optimus, it was only supported on Windows 7. Allegedly, the company is working to make interaction between its drivers and the Bumblebee Open Source Project. The Bumblebee project is working to make Optimus-powered laptops work with Linux operating systems.

What do you think of the two statements by Linus and NVIDIA? Should NVIDIA be held accountable for Optimus support under Linux? Is the company doing enough to support the OS? Or is Linus wrong? Let us know in the comments below!

Personally, as much as I like Linux, I don’t think NVIDIA should have to go out of its way to support Optimus on Linux. At least, not until the Linux OS is the operating system that comes pre-installed on an Optimus notebook. At that point, it would be on NVIDIA to provide support. Until then, they don’t have to support it on aftermarket / third part operating systems. With that said, better Linux support couldn't hurt PR-wise. As far as Linux and NVIDIA working together in a more general sense, I think that the company could certainly do more for Linux on the desktop, especially being a Linux Foundation member, but I don't think they will until it is more financially viable to do so.

The full PR statement is available after the break.
