Ah, Kepler: the (originally intended as) midrange graphics card architecture that took the world by storm and allowed NVIDIA to take it from the dual-GPU GeForce GTX 690 all the way down to budget discrete HTPC cards. So far this year we have seen the company push Kepler to its limits by adding GPU boost and placing it in the GTX 690 and GTX 680. Those cards were great, but commanded a price premium that most gamers could not afford. Enter the GTX 670 and GTX 660 Ti earlier this year and Kepler started to become an attractive option for gamers wanting a high-end single GPU system without breaking the bank. Those cards, at $399 and $299 respectively were a step in the right direction to making the Kepler architecture available to everyone but were still a bit pricey if you were on a tighter budget for your gaming rig (or needed to factor in the Significant Other Approval Process™).
Well, Kepler has now been on the market for about six months, and I’m excited to (finally) announce that NVIDIA is launching its first Kepler-based budget gaming card! The NVIDIA GeForce GTX 650 brings Kepler down to the ever-attractive $109 price point and is even capable of playing new games at 1080p above 30FPS. Not bad for such a cheap card!
With the GTX 650, you are making some sacrifices as far as hardware, but things are not all bad. The card features a mere 384 CUDA cores and 1GB of GDDR5 memory on a 128-bit bus. This is a huge decrease in hardware compared to the GTX 660 Ti’s 1344 CUDA cores and 2GB memory on a 192-bit bus – but that card is also $200 more. And while the GTX 650 runs the memory at 5Gbps, NVIDIA was not shy about pumping up the GPU core clockspeed. No boost functionality was mentioned but the base clockspeed is a respectable 1058 MHz. Even better, the card only requires a single 6-pin PCI-E power connector and has a TDP of 64W (less than half of its higher-end GeForce brethren).
The following chart compares the specifications between the new Geforce GTX 650 through the GTX 670 graphics card.

The really important question is how well it handles games, and NVIDIA showed off several slides with claimed performance numbers. Taking these numbers with a grain of salt as they are coming from the same company that built the hardware, the GTX 650 looks like a capable GPU for the price. The company compared it to both its GTS 450 (Fermi) and AMD’s 7750 graphics card. Naturally, it was shown in a good light in both comparisons, but nothing egregious.
NVIDIA is claiming an 8X performance increase versus the old 9500 GT, and an approximate 20% speed increase versus the GTS 450. And improvements to the hardware itself has allowed NVIDIA to improve performance while requiring less power; the company claims the GTX 650 uses up to half the power of its Fermi predecessor.
The comparison between the GTX 650 and AMD Radeon HD 7750 is harder to gauge, though the 7750 is priced competitively around the GTX 650’s $109 MSRP so it will be interesting to see how that shakes out. NVIDIA is claiming anywhere from 1.08 to 1.34 times the performance of the 7750 in a number of games, shown in the chart below.
If you have been eyeing a 7750, the GTX 650 looks like it might be the better option, assuming reviewers are able to replicate NVIDIA’s results.
Keep in mind, these are NVIDIA's numbers and not from our reviews.
Unfortunately, NVIDIA did not benchmark the GTS 450 against the GTX 650 in the games. Rather, they compared it to the 9500 GT to show the upgrade potential for anyone still holding onto the older hardware (pushing the fact that you can run DirectX 11 at 1080p if you upgrade). Still, the results for the 650 are interesting by themselves. In MechWarrior Online, World of Warcraft, and Max Payne 3 the budget GPU managed at least 40 FPS at 1920x1080 resolution in DirectX 11 mode. Nothing groundbreaking, for sure, but fairly respectable for the price. Assuming it can pull at least a min of 30 FPS in other recent games, this will be a good option for DIY builders that want to get started with PC gaming on a budget.
All in all, the NVIDIA GeForce GTX 650 looks to be a decent card and finally rounds out the Kepler architecture. At this price point, NVIDIA can finally give every gamer a Kepler option instead of continuing to rely on older cards to answer AMD at the lower price points. I’m interested to see how AMD answers this, and specifically if gamers will see more price cuts on the AMD side.
If you have not already, I strongly recommend you give our previous Kepler GPU reviews a read through for a look at what NVIDIA’s latest architecture is all about.

Update: US-based retailers are starting to list the GTX 660 Ti as well, and at least one card is listed for $299, so there may be some hope despite the $349.99 MSRP. See the $299 PNY GTX 660 Ti graphics card here.
The GTX 660 Ti is an NVIDIA Kepler-based graphics card that has seen several leaks and even a full review ahead of official release. In the leaked review, rumored specifications were confirmed, and the card was shown to be very close to the existing GTX 670 GPU. Sometimes it was merely a couple of frames behind the $400+ GPU.
On the podcast, Ryan, Josh, and Jeremy speculated that–should the GTX 660 Ti be priced closer to the $300 mark in the rumored $300-400 pricing–it would be a very desirable gaming graphics card. Hardware-wise, the GTX 660 Ti is nearly identical to the GTX 670, and only sees a reduction in the memory bus from 256-bit to 192-bit. For a $100 cheaper card, gamers would be getting extremely close to the performance of the much more expensive GTX 670 Kepler card.
Unfortunately, it may not be the gaming card that people have been hoping for. According to Tom’s Hardware, a Swedish retailer has listed the GTX 660 Ti on its website for pre-orders at just under $400. At that price point, the GTX 660 Ti is much less desirable, and will be hard to justify versus springing for the GTX 670 for a bit more money.
Here’s hoping that the pre-order pricing is simply higher than the prices people will see once actual cards from NVIDIA and partners are officially released en masse. Do you think that there is still hope for the GTX 660 Ti as the gaming card of choice, or will you be looking elsewhere?

Last week, additional information leaked about the upcoming Kepler-based NVIDIA GTX 660 Ti graphics card. Those rumors suggested that the GPU would be very similar to the one found in existing GTX 670 (which we recently reviewed).
We speculated that the GTX 660 Ti could be an awesome card, assuming the price was right. While we do not have any pricing information–the best guess from rumors is that it is in the $300 to $400 range–as a result of Tweaktown breaking the release date, we now know that the latest rumors were true.
The GTX 660Ti will feature 1344 CUDA cores and 2GB of GDDR5 memory on a 192-bit memory bus. This puts the GTX 660 Ti very close to the current 670 in terms of potential performance. According to the leaked benchmarks, that seems to be the case. The GTX 660 Ti is only a couple of frames behind the GTX 670 in Just Cause 2 and Dirt 3, for example. Considering this card is likely to use a bit less power and cost less, it is shaping up to be a rather desirable card. If this ends up being on the low end of the $300-400 range (rumors suggest otherwise, however), I suspect many gamers are going to opt for this new Kepler card rather than the more expensive and only very slightly faster GTX 670.
What do you think about the GTX 660 Ti, is the card you were hoping for?

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.
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.

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.

Editor's Note: We are getting a lot of flak for posting this story today, telling us that we are "giving the site credibility", referring to the Pnosker site that first started the recall rumor, simply by posting about it on our site. Even though our post by Tim states to "take the leak with a grain of salt" and that "these GPUS go through rigorous testing and certification", some people think we were in the wrong to post about this.
So let me be perfectly clear - the recall referenced in the story below is almost assuredly complete and utter BULLSHIT.
According to Pnosker, NVIDIA is allegedly looking into recalling all Kepler based, 600-series graphics cards. Such a recall would affect users that have purchased GTX 670, GTX 680, and GTX 690 GPUs. The website has stated that their source has indicated that the graphics cards will possibly be recalled because the chips suffer from performance degradation after prolonged periods of heavy usage.
While their source has reportedly been correct in the past, the author cautions readers to take the leak with a grain of salt. Other websites that have picked up on this have mentioned that these GPUs go through rigorous testing and certification processes before getting to the market, so this rumor does not have much ground to stand on. Another reason to take this report with a shaker-full of salt is that if there was such a defect in the Kepler GPU, it would be more likely to completely fail rather than continue working with degraded performance.
This rumor is likely just that: a rumor. Why such a rumor was started is unknown but your Kepler graphics card purchases are probably safe from performance degradation, though they may not get as high of a boost clock as other users’ cards.
UPDATE @ 7:30pm ET: To quote from NVIDIA PR - "There is no truth to this rumor."

Tagged: msi, HD7950, hd 7950, graphics cards, gpu, amd
MSI today officially announced their new Radeon HD 7950 graphics cards with Twin Frozr III coolers. Specifically, the new cards are part of the "R7950 Twin Frozr 3GD5/OC" series. The new Twin Frozr III cooler features a nickel plated block, two 8mm Superpipes (heatpipes), and dual 80mm propeller blade fans that, according to MSI, delivers up to 10 degrees Celsius lower GPU temperatures versus reference coolers. Further, the dark gray Twin Frozr III cooler reduces noise by 13.7dB by using two slower spinning fans versus the single reference design fan spinning twice or more as fast. This extra bit of overclocking headroom has allowed MSI to claim a large "core and memory voltage potential providing up to 37.5% overclockability" Just like the company's motherboards, they are advertising the new graphics cards as being built with Hi-c CAP Super Ferrite Choke and solid capacitors that pass MIL-STD-810G testing. Based on the AMD 28nm Radeon HD 7950 reference design, the card supports the PCI Express 3.0 interface. Also, the card features 1 DVI, 1 HDMI, and two Mini-DisplayPort video outputs.
Further specifications include 3 GB of GDDR5 memory on a 384 bit bus, a core clock speed of 880 MHz, and memory clock of 5,200 MHz (effective, 1,300 MHz base). The card itself measures 261mm x 111mm x 38mm, (just under 10.3") which means that it should fit comfortably inside most Mid Tower (or larger) cases. While the 80 MHz increase in GPU clock speed over the reference design is not saying much, the cards themselves should have plenty of overclocking headroom beyond what MSI does at the factory. In our review of the AMD Radeon HD 7950 graphics card with reference cooler we achieved a nice 1050 MHz clock speed, and the "Supa-pipe" (as Josh likes to say) powered Twin Frozr III 7950 cards should be able to go even further beyond that, specific GPU permitting of course.
In addition to the new Twin Frozr III cooler powered cards, MSI is releasing a version of the Radeon 7950 with a reference design cooler and another Radeon 7970 card with a reference cooler to provide gamers with plenty of alternative options. Unfortunately, there is no word (yet) on pricing or availability. The Twin Frozr III version of the 7950 sure looks a lot cooler, so it will be interesting to see if it actually keeps the GPU cooler (heh).
