An interesting rumor floating around the internet concerns a new AMD 7950 graphics card. Specifically, a forum post over at EXPReview hinted at a new GHz Edition 7950 card. They reference a source and a photo of a graphics card with GHz Edition markings and two six-pin PCI-E power connectors. They further quoted a source that said AMD would be releasing a fourth card to its 7000-series lineup. In other words, there was not a whole lot to go on.
The alleged AMD Radeon HD 7950 GHz Edition graphics card.
I saw the rumor a couple of days ago, but decided to let it sink in for a bit before writing about it. After some thought and internal conversations, I think a 7950 GHz edition is plausible, and certainly a possibility. With the addition of the HD 7970 GHz Edition (which we recently reviewed), AMD now has a 7900 series part with its new GPU Boost (aka Powertune Boost) technology. Unfortunately, that tech can not simply be rolled out to the other existing 7900 series cards meaning that the original 7950 and 7970 are stuck without boost, leaving a gap in its lineup. Because of that, it seems logical that AMD would want to fill in that gap with a refreshed 7950 part that has higher clocks and GPU boost.
The 7970 GHz Edition helped AMD stay competitive with the NVIDIA GeForce GTX 680 and enabled AMD to (re)claim it had the fastest single GPU card. That card was enabled by AMD finding extra headroom and higher bins in its 28nm GPUs. The current Radeon HD 7950 runs at an 800 MHz GPU clock speed and a 5GHz GDDR5 effective clock speed. It is unclear if the company’s chips have enough headroom that they are able to overclock 7950 oriented silicon or if they are simply reworking the bins such that the 7950 GHz Edition is either using silicon that just barely can’t make the cut as a 7970 GHz Edition or AMD is artificially locking down 7970 GHz chips to make these proposed 7950 GHz GPUs. Apart from the increased clock speeds and GPU Boost, the rumored card is said to maintain the same hardware specifications as the existing 7950. Mainly, that means 1,792 stream processors, 112 texture units, and the same number of transistors – 4.31 billion – on a 28nm process. In comparison, the 7970 has 2,048 stream processors and 128 texture units.
As mentioned above, such a chip sounds like a logical step for AMD. By refreshing the 7950 with higher clock speeds and adding GPU Boost functionality it will be fight with the GeForce 670 for the performance crown, and may even come close to 680/7970 performance when overclocked further. I do have a couple of questions about this rumored card, however. Specifically, I am wondering if AMD will simply refresh the 7900 series cards and let the original releases fade out as the stock dwindles or if they will keep them around. I’m leaning towards the later but it will still be interesting to see, and it also makes me wonder how much a 7950 GHz Edition will cost me.
I’m curious what you think about the rumor though, do you think it has any merit? And assuming this is legit, where do you think it will stand performance-wise versus NVIDIA’s products?
If you are curious about how AMD’s new GPU Boost technology works, be sure to check out our Live Review of the Radeon HD 7970 GHz Edition with AMD’s Evan Groenke where we are given a live demonstration showing how it works and some background on the technology.

Gigabyte has had an overclocked version of the Radeon HD 7770 graphics card for a couple months now, but the company is already readying a second revision of the card. Curiously, the new revision will maintain the same hardware but will run at slightly lower clock speeds. While the current revision (1.0) runs at 1100 MHz and 5000 MHz for the GPU core and memory respectively, the updated graphics card will run at 1050 MHz and 4500 MHz.
Beyond the lower clock speeds, the new revision of the GV-R7770 OC card maintains the same PCB, chips, and cooler design. That hardware includes a 28nm GPU, 1GB of GDDR5 memory on a 128-bit interface, and a PCI-E 3.0 expansion slot. Display outputs include a DVI port, full-size HDMI port, and two mini DisplayPorts. It also maintains the same custom Gigabyte heatsink and fan.
According to Videocardz, users will be able to identify which revision they are getting before handing over any money by looking at the box. Alternatively, users can identify which revision it is by looking at the sticker on the underside of the card just above the PCI-E connector. As a new revision, especially with the release of higher-binning chips from AMD, it is a bit confusing that the card is being released with lower clock speeds than its predecessor. It may be that the higher factory overclock was not stable on enough cards and Gigabyte was having to deal with too many returns – that’s only a guess though.
All the same, if you are shopping for a 7770 graphics card and have been considering the Gigabyte model, be sure to double check which revision you are getting.

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.
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.

Tagged: tahiti, gpu, ASUS ROG, asus, amd, 7970
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.
