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.
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.
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.

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.
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.
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.

ASUS recently posted a few teaser photos of its upcoming Republic of Gamers branded 7970 graphics card. The Matrix HD 7970 is a three slot design with the company’s DirectCU II heatsink, dual fans, DIGI+ VRM, and (of course) AMD’s 7970 Tahiti GPU core. While likely not based on the higher-binned cores used in the new 7970 GHz Edition graphics cards, with the large cooler and extra power phases that ASUS is packing into this Matrix GPU it should overclock to similar levels of performance.
The card features fans, and a large dual slot cooler with the traditional red and black ROG theme. The ASUS and Matrix logos are etched into the side of the card as well. The PCB is black and further covered by a bracing plate to reinforce the PCB to support the weight of the cooler. On the front of the card, it houses an air vent, two DVI connectors, and four DisplayPort video outputs. On the back of the card are four buttons. Two of the buttons with plus and minus symbols let you adjust the core voltage in preset jumps. The Safe Mode button next to the minus button clears the overclocks from the BIOS and resets the card to default settings. Finally, the red button will spin the fan up to 100% to overclock the card as far as possible. They also have a bank of LEDs below the buttons that offer at-a-glance load monitoring (really only useful for those testing outside a case...). In the rear corner of the card is two eight pin PCI-E power connectors. Then, on the underside (top when installed in the case) of the graphics card’s PCB, ASUS has a VGA Hotwire port which allows the card to interface with the ASUS OC Key and Extreme edition motherboards (such as the Maximus V and Rampage IV Extreme). There are also voltage checking points.
Internals are somewhat similar to ASUS Radeon HD 7970 DirectCU II, but with some aspects ratcheted up. The power phases, for example, have increased from 12 phases to 20 on the Matrix card. It continues to use the 7970 “Tahiti” GPU with 2048 shaders, 32 ROPs, and AMD’s Graphics Core Next architecture. ASUS is packing 3GB of GDDR5 memory with a 384-bit memory interface. ASUS has stated that both the GPU core and memory will be overclocked from the factory. Unfortunately, they have not released any specific numbers. We will have to wait until the card is closer to the launch date for that information.
The ASUS ROG Matrix graphics card will be launching in Q3 of 2012. It will be aimed at extreme overclockers – especially those that are already using Republic of Gamers branded motherboards from ASUS. What do you think of this new card, especially now that AMD has launched its 7970 GHz Edition reference GPU? You can find more photos of the card over at the ASUS website.

Introduction, Driver Interface
There exist a particular group of gamers that are consumed by dreams of gigantic dual-SLI laptops that replace towering desktops. And who can blame them? Walking into a LAN party with a $5,000 laptop under your arm is the geek equivalent of entering a party wearing a $2,500 jacket or driving through your neighborhood in a $250,000 car. We can dream, right?
On the other hand, those super-powerful laptops are a bit...boring from a critic’s standpoint. Why? Because they are almost always excellent machines (due to price) and because most readers gandering at a review (of an expensive gaming laptop) I pen about will never buy one – again, due to the price.
Most folks – even many geeks – lust over a beefy gaming rig, but end up buying a $600 to $1000 multimedia laptop. This is the laptop that the average person can actually afford, regardless of his or her enthusiasm about computer hardware.
In the past, this market segment was a gaming wasteland, but that began to change about five years ago. The change was due in part to the fact that many game developers started to veer away from (a focus on) jaw-dropping graphics in favor of expanding their potential markets by going after clients with average/medium-range hardware.
About two and a half years ago Intel (again) committed to raising the bar on integrated graphics with the release of Intel HD and has since consistently improved its IGP offering with each new generation. AMD has done the same with its Fusion products and NVIDIA (already in the game with its numerous x10/x20/x30M products) just recommitted to power efficient GPUs with its Kepler architecture.
These changes mean that “serious” gaming is now possible on an inexpensive laptop. But how possible? What sacrifices do you make and how do low-end IGPs and GPUs stack up against each other?

Tagged: tahiti, graphics, gpu, computex, binning, amd, 7970 ghz edition
AMD is having a string of successes with its 28nm 7000 series graphics cards. While it was dethroned by NVIDIA’s GTX 680, the AMD Radeon HD 7970 is easier to get a hold of. It certainly seems like the company is having a much easier time in manufacturing its GPUs compared to NVIDIA’s Kepler cards. AMD has been cranking out HD 7970s for a few months now and they have gotten the binning process down such that they are getting a good number of pieces of silicon that have a healthy bit of overhead over that of the 7970’s stock speeds.
And so enters Tahiti 2. Tahiti 2 represents GPU silicon that is binning not only for HD 7970 speeds but is able to push up the default clock speed while running with lower voltage. As a result, the GPUs are able to stay within the same TDP of current 7970 cards but run faster.
But how much faster? Well, SemiAccurate is reporting that AMD is seeing as much as a 20% clock speed improvement over current Radeon HD 7970 graphics cards. This means that cards are able to run at clock speeds up to approximately 1075MHz – quite a bit above the current reference clock speed of 925MHz!
The AMD 7970 3GB card. Expect Tahiti 2 to look exactly the same but run at higher clock speeds.
They are further reporting that, because the TDP has not changed, no cooler, PCB, or memory changes will be needed. This will make it that much easier for add in board partners to get the updated reference-based GPUs out as quickly as possible and with minimal cost increases (we hope). You can likely count on board partners capitalizing on the 1,000MHz+ speeds by branding the new cards “GHz Edition” much like the Radeon 7770 has enjoyed.
With 7970 chips having overhead and binning higher than needed, an updated and lower-power using refresh may also be in order for AMD’s 7950 “Tahiti Pro” graphics cards. Heck, maybe they can refresh the entire lineup with better binned silicon but keep the same clock speeds in order to reduce power consumption on all their cards.

Tagged: video, sapphire, radeon 7770, passive cooling, graphics card, gpu, computex
Not to be left out of the Computex news, graphics card manufacturer Sapphire Technology unveiled a passively cooled AMD Radeon 7770 graphics card running at reference clock speeds. Following the release of the company’s factory overclocked Vapor-X 7770, the new Sapphire HD 7770 Ultimate 1GB card is the first to sport a passive cooler – other vendors are going in the opposite direction by using custom (active) coolers to push up reference clockspeeds for factory overclocked cards.
What makes the sapphire card neat is that the company did not have to underclock the GPU or memory in order to make a passive cooler feasible. With this card, you will get a silent GPU with the same specs and speeds as the reference 7770 we recently reviewed. The card looks to take up about two PCI expansion slots and utilizes a horizontal stack of vertically aligned (if that makes sense?) aluminum fins connected to the GPU via four heatpipes. Because of the cooler, the card is about 25% longer than a reference card, so keep that in mind if you are considering this for a HTPC build using a tiny case.
Beyond the cooler, which is arguably the most important aspect of the card, the Saphhire 7770 Ultimate 1GB is nearly identical to AMD’s reference design. The only major change is that Sapphire had to move the GDDR5 memory chips to the opposite (top, when installed in the case) side of the PCB in order to accommodate the cooler. With that said, the video outputs on the graphics card are a small improvement over the reference design with an additional DVI port (thanks to not needing a full fan grill in the second PCI slot) bringing the total to two DVI ports, one full size HDMI, and one full size DisplayPort. Otherwise, the GPU is stock, running at 1GHz while the 1GB of GDDR5 memory is likely running at 1125 MHz (stock speeds). The Cape Verde-based graphics card contains 640 stream processors, 1.5 billion transistors, 1.28 Teraflops of compute performance, and a Texture fill rate of 40 giga-transfers per second (GT/s). The full specifications of the 7770 GPU core can be found in our review.
The MSRP of reference AMD HD 7770 cards is $159 but expect the Sapphire card to come in a bit above that number thanks to the custom cooler. You can find more photos of the passively cooled Sapphire GPU over at AnandTech who managed to snag some good shots of the card at the company’s Computex booth.
In case you missed it, our video review of the HD 7770 card is embedded below in which we show off the (7770 and 7750) card also show off several custom 7770 designs from MSI, XFX, and others. It should bring you up to speed on what the 7770 is and where it stands in terms of performance with other cards from AMD and NVIDIA.
Earlier this year I had the chance to take a look at the first ultrabook with discrete graphics, the Acer Aspire Timeline Ultra M3. My review was not particularly favorable, but the idea of placing discrete graphics in an ultrabook is both compelling and necessary. Intel’s low-voltage processors have difficulty with gaming when paired with the HD 4000 IGP and this flaw is difficult to excuse in products typically priced at $800 or above.
Four new ultrabooks with NVIDIA discrete GPUs have been unveiled to tackle the problem of gaming with a slim laptop. The list includes two laptops from Acer, two laptops from Gigabyte and one from ASUS.
The Gigabyte U2442N, which has a 14” 1600x900 display and a GeForce GT 650M GPU, is obviously the most powerful and the product that offers the most promising gaming experience on paper. Only the ASUS UX32 looks questionable. There’s no way that a GeForce GT 620M is going to handle gaming on a 1080p display.
Unfortunately, a closer look at the announcement suggests these product lines aren’t that exciting. The Gigabyte laptops have received a lot of positive attention, but Gigabyte has no meaningful presence in the North American laptop market and it’s nearly guaranteed the laptop won’t be popular on this side of the pond. The Acer M5-581TG appears to be an Ivy Bridge updated version of the Acer Aspire M3 that we reviwed – and did not like – while the M5-481TG is just a smaller version.
That leaves the ASUS UX32 and its GT 620M which, although likely quicker than Intel HD 4000, isn’t sufficient for serious gaming.
Hopefully NVIDIA will be able to bring discrete graphics to more products from larger manufacturers, but the fact so few companies have gone this route suggests there is some underlying reason. My personal guess? Heat. The Acer Aspire M3 became quite toasty during load. It’ll be interesting to see if the U244N has some design trick that makes the GT 650M manageable – or if Gigabyte, like Acer, doesn’t mind putting out a laptop with high exterior temperatures.
NVIDIA recently revised its notebook GPU lineup, but there was one part notably missing – the GTX 680M. The x80M part has been NVIDIA’s fastest mobile GPU in each generation for some time, so we knew that a GTX 680M was coming. We had only two questions. When? And what architecture will it be based on?
Now we have the answers to both questions. NVIDIA has pulled the wraps off its flagship component. The new GTX 680M is a Kepler component (unlike other high-end 600 series parts, which are Fermi) packing 1344 CUDA cores and up to 4GB of GDDR5.
The green team is laying out some big numbers in its press release by claiming that performance is up about 80% in comparison to the GTX 580M and 30% in comparison to the AMD Radeon 7970M. NVIDIA also says that the new part will play every game available today at 1080p with maximum in-game settings.
Other selling points include NVIDIA’s FXAA and TXAA, Adaptive V-Sync, Optimus, SLI, PhysX and 3D Vision. The company is clearly making a strong effort to distinguish itself from AMD not only with performance but also with features.
Five launch laptops were announced. They include the Alienware M17x and M18x, the MSI GT70 and the Clevo P150EM/P170EM. The Clevo units are the chassis used by companies like Maingear, Origin and other boutiques. Only the M18x has confirmed SLI support and only the M17x has confirmed 3D Vision support. Pricing has not been announced.
We will of course be looking to obtain a review unit so we can see if the GTX 680M is as mightly as claimed.

Jon Peddie's newest report on the state of the graphics card market has arrived and while the news is not good it is nowhere near as bad as it could have been. The graphics card market had a very large hurdle to deal with over these last few quarters which is why the total market declining 0.8% from last quarter and a 3.38% decline from Q1 2011 is not terrible news. The impact came from the flooding in Thailand, which has been causing lowered sales for most of the PC market this year. With hard drives being in such short supply the number of systems that could be built by vendors dropped dramatically, those systems which were built were noticeably more expensive than before the flood as the price of hard drives doubled in some cases. With less systems being built and sold there was less demand for GPUs from the vendors, thankfully the industry has recovered from the shortage and we are seeing prices and supplies returning to their normal levels.
When you break it down by company, only AMD saw growth from last quarter, though at a 0.3% increase it was not so much growth as simply holding their ground. NVIDIA has stopped reporting on their IGP sales which, believe it or not, still sell in Asia and so saw a drop of 4.5% from last quarter. Some of that decline will be due to the change in reporting but the lack of Kepler stock has certainly hurt their sales as well. Intel saw a decline of 1.3% from the previous quarter again likely due to the influence of the hard drive shortage reducing the number of systems which were sold.
When you look at only discrete cards, the sales increased 2.7 % from the last quarter but were down 11% from this time last year, thanks to the GPU now present on both AMD and Intel processors. With Llano and Trinity as well as SandyBridge and Ivy Bridge we saw the arrival of onboard graphics which provided enough horsepower that many casual users no longer need a discrete GPU. Previous generations of IGPs and onboard graphics cores struggled to play HD video without stuttering and they were essentially useless if they were called upon to power even casual games. The new generations of processors can not only handle HD video but are quite capable of light gaming duties. They also made possible tablets and extremely small laptops, aka Sleekbooks and Ultrabooks, which provided good enough performance for many users and these small form factors have little space for discrete GPUs. As both AMD and Intel's processors have a graphics core they count towards the total graphics card market share which is good news for them but not for NVIDIA who count on add in card sales exclusively. On the plus side, when you examine add in card sales for laptops alone, NVIDIA actually saw a gain of 5%.
