Why Boost you may ask? If you guessed that NVIDIA added their new Boost Clock feature to the card you should win a prize as that is exactly what makes the GTX 650Ti special. With a core GPU speed of 980MHz, boosting to 1033MHz and beyond this card is actually aimed to compete with AMD's HD7850, not the newly released HD7790, at least the 2GB model is. Along with the boost in clock comes a wider memory pipeline and a corresponding increase in ROPs. The 2GB model should be about $170, right on the cusp between value and mid-range but is the price worth admission? Get a look at the performance at [H]ard|OCP.
"NVIDIA is launching the GeForce GTX 650 Ti Boost today. This video card is priced in the $149-$169 price range, and should give the $150 price segment another shakedown. Does it compare to the Radeon HD 7790, or is it on the level of the more expensive Radeon HD 7850? We will find out in today's latest games, you may be surprised."

The GTX 650 Ti Gets Boost and More Memory
In mid-October NVIDIA released the GeForce GTX 650 Ti based on GK106, the same GPU that powers the GTX 660 though with fewer enabled CUDA cores and GPC units. At the time we were pretty impressed with the 650 Ti:
The GTX 650 Ti has more in common with the GTX 660 than it does the GTX 650, both being based on the GK106 GPU, but is missing some of the unique features that NVIDIA has touted of the 600-series cards like GPU Boost and SLI.
Today's release of the GeForce GTX 650 Ti BOOST actually addresses both of those missing features by moving even closer to the specification sheet found on the GTX 660 cards.
Our video review of the GTX 650 Ti BOOST and Radeon HD 7790.
Option 1: Two GPCs with Four SMXs
Just like we saw with the original GTX 650 Ti, there are two different configurations of the GTX 650 Ti BOOST; both have the same primary specifications but will differ in which SMX is disabled from the full GK106 ASIC. The newer version will still have 768 CUDA cores but clock speeds will increase from 925 MHz to 980 MHz base and 1033 MHz typical boost clock. Texture unit count remains the same at 64.

Earlier this month AMD announced that it was upgrading the Radeon HD 7950 graphics card to run at higher clockspeeds and with boost capability. The PowerTune with Boost technology uses digital temperature estimation and dynamic voltage control to increase the GPU core clockspeed above the base clockspeed in most applications.
Using a new BIOS, manufacturers would be able to refresh their existing lineups to enable PowerTune with Boost and higher clockspeeds. Original graphics cards along with the refreshed boost-capable GPUs will be sold in parallel (the original 7950s are not being phased out completely yet). And in a somewhat similar situation to unlockable 6950 reference cards, users could attempt to flash the new boost-capable BIOS to their original HD 7950s – though it is not guaranteed to work (and that's where the OEM certification becomes useful).
AMD Add In Board (AIB) partner PowerColor (who recently launched the Devil 13 7990) has released its second Radeon HD 7950 graphics card with boost in the form of its custom – and factory overclocked – PCS+ graphics card. The original PCS+ and new "Boost State" graphics card will be sold simultaneously, and (fortunately) you will be able to tell them apart by the red Boost State sticker on the box and the new "Boost State" labeling tacked onto the product name at online retailers. The new PowerColor PCS+ HD7950 3GB GDDR5 Boost State graphics card steps up the factory overclock to 900 MHz base while keeping the same PCS+ cooler and PCB design. The triple-slot design incorporates a cooler with dual 92mm fans and three 8mm heatpipes connected to an aluminum fin array. The PCB hosts the 7950 GPU, 3GB of GDDR5 RAM clocked at 1250 MHz, 6+2+1 power phase, digital PWM circuitry, and ferrite core chokes. A dual BIOS switch and two 6-pin PCI-E power connectors are also present. Video outputs include two mini-DisplayPorts, one HDMI, and one DVI.
Those specifications remain unchanged, and the new graphics card is essentially a PCS+ HD7950 that has been certified to run with the updated BIOS at the new GPU clockspeeds (and with boost). It may be possible to flash an original PCS+ 7950 with the updated BIOS and get the same performance as the new card but there are, obviously, no guarantees. However, because of the dual BIOS switch the risk of permanent damage is minimal (though the warranty would likely be void).
There is no word on pricing or when exactly you will be able to buy the new "Boost State" cards, but they should start showing up at retailers soon. Expect pricing to be a bit above the original PCS+ GPU's (approx.) $330 retail price.

Gamers have been eagerly awaiting the release of the midrange NVIDIA graphics card thanks to some rather enticing rumors and leaks. Due to launch sometime soon, the GTX 660 Ti is packing some quality hardware and may be the next 8800GT as far as popularity levels with gamers craving the best price/performance. However, that is dependent on pricing–which has been up in the air for a while. Rumored prices have included an MSRP of $349 and retail pre-orders for $299 and just under $400 (and guesses everywhere in between).
US-based computer retailer CompUSA has provided us with further information that suggests the price will, in fact, be the ever-desired $299 price point rather than previous rumors that suggested it would be priced closer to the GTX 670. Gamers rejoice!
Specifically, a reference version of the PNY-manufactured NVIDIA GTX 660 Ti recently appears on CompUSA’s website where customers could purchase it. This card is listed as being model number “VCGGTX660TXPB-C Bundle.” While it is unclear what the “-C” designator means, it is more proof that it is the same (or a very similar) model as the card leaked by MacMall (when it showed up for pre-order ahead of the release date). Speaking of bundles, the CompUSA card gets even better as it is the PNY GTX 660 Ti and a game coupon for Borderlands 2 for the $299 price–not bad at all.
While I have not personally ordered one (so I can’t confirm if CompUSA will actually sell it to me ahead of the official release or if it was just a mistake on its part for making the store page live early), you can try to get your hands on the 660 Ti now for $299 USD.
I’m extremely happy to see the $299 price, and I look forward to see the cards from other manufacturers. Custom and factory overclocked cards should also be interesting as far as pricing and where they fit compared to saving up a bit more money and simply going with a GTX 670. What do you think, will you be picking one of these graphics cards up?

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?
