"For the technically inclined, it is interesting that the GTX 980 Ti is clocked slower than previously at 1,000MHz. But it has better pixel and texture fillrate, while also packing a lot more transistors -- 8,000 compared to 5,200 of the GTX 980. When you look at the specs in detail, the GTX 980 Ti is basically a cheaper version of Nvidia's ultimate piece of hardware, the $999 Titan X, having only 6GB of VRAM instead of the 12GB on the latter."
"I really, really liked Nvidia’s Titan X. Yes, it carries an exorbitant price tag of $999, but it remains the most powerful single-GPU graphics card on the market and it integrates nicely into everything from super towers to compact mini-ITX builds. But would I sacrifice a paltry 3% of performance and choose “only” 6GB of VRAM if it meant paying $350 less for a nearly identical part? Absolutely! And that’s what makes Nvidia’s new 980 Ti so appealing. (It also means Nvidia’s GTX 980 will see a price reduction down to $499.)"
"NVidia's GTX 980 Ti is interesting. At $650, it's only $100 away from where most GTX 980s will soon rest – or $150 from MSRP – and that makes it an appealing purchase. The performance delta between the 980 and 980 Ti is large enough that there are noticeable gains in higher resolution gaming, but that also doesn't relegate the 980 to the trash – it's still a viable gaming solution for most users. At 1080 especially, the GTX 980 would be a better buy of the two, just looking at pure value and famerate output.
The 980 Ti doesn't invalidate the GTX 980 and owners shouldn't feel “buyer's remorse” for a purchase, though some manufacturers may offer step-up programs should an upgrade be desired. As far as we're concerned, the GTX 980 remains a powerful, cost-efficient card, but builders with slightly more cash should seriously consider the upgrade to a Ti if building for 1440 or 4K."
"If you don’t have the cash to splash on Nvidia’s eyeball-melting Titan X, then this is the GTX 980 Ti — the next GeForce flagship, designed for smooth frame rates at 1080p, 1440p and even 4K gaming of brand new AAA titles like The Witcher 3, GTA V and Project CARS. It’s the newest and most powerful 9-series graphics card from Nvidia, and overtakes even the regular GTX 980 by a fair margin."
"The GTX 980 Ti is an absolute monster, a graphics card that will ultimately set the stage for a battle with AMD on both the pricing and performance fronts. Even without looking into our crystal ball to six months down the road, it is obvious that NVIDIA has thrown down a gauntlet with. AMD’s next architecture still looms large but it remains an unknown while the GTX 980 Ti posts spectacular results and will be available tomorrow morning. "
"The GeForce GTX 980 Ti performed very well throughout our entire battery of tests. If you took the time to inspect its specifications and features, you were probably expecting something that performed similarly to a Titan X, and that is exactly what NVIDIA delivered. The GeForce GTX 980 Ti finished every tests only a couple of percentage points behind the Titan X, making it easily the second fastest single-GPU powered graphics card on the market. The GeForce GTX 980 Ti’s power consumption was also just below the Titan X’s. And the card also overclocked well, hitting over 1370MHz in our tests."
"The GTX 980 Ti will cost you $649.99, and it will be available within a week, according to the company. And is it any good? Well, The Tech Report's review says that it offers "nearly the same performance as the Titan X at a considerable discount." So while the 980 Ti certainly isn't cheap, it's not bad at all compared to the $1,000 asking price for the mighty Titan X. The GTX 980, meanwhile, has been dropped by $50 to $499.99.
Lastly, Nvidia says it has developed new rendering tech to make processing for virtual reality headsets more efficient. The images projected by VR headsets are not the same as what you see on a computer monitor — they are distorted to a fisheye view. When viewed through the lenses of the headset, this image appears all-encompassing. According to Nvidia, current tech must render the full 2D image and then distort it, which means the GPU is wasting resources on pixels that don't even make it into the final product. Nvidia's new VR APIs for developers, called GameWorks VR, analyze the image in separate portions, and render the periphery in lower resolution than the middle. We'll have to see the tech in action, but if it works out as advertised, it could help make it possible for people to join in on the virtual reality craze without upgrading to a massively expensive gaming rig.
