NVIDIA GeForce GTX 650 Ti Review


More Performance For Your Budget

The GTX 650 Ti comes packed with features that are unprecedented for a card of its size and price. To cater to modern 1080p gamers, NVIDIA integrated the same GK106 GPU used in the GTX 660. Four SMXs with 768 CUDA Cores and 64 texture units round out the card's graphical prowess. Compared to the standard GTX 650, the Ti boasts twice the number of CUDA Cores and texture units in addition to more memory bandwidth, making it 40% faster on average. Thanks to Kepler's focus on power efficiency, the GTX 650 Ti consumes 22% less power under load than the GTX 550 Ti. 

Microsoft DirectX 11

A discussion of DX11 really boils down to two things: tessellation and displacement mapping. Put simply, a displacement map stores height information to give texture to surfaces it is applied to. Limitations arise from a lack of vertices to depict complex textures. Tessellation is able to slice and dice the polygons to deliver highly textured characters that border on film-like realism. Given that tesselation is programmable in DirectX 11, challenging graphics problems like bump mapping, smoothing, object popping, and artwork scaling. This means in a nutshell that gamers will enjoy all the details of their favorite games both far away and close up. A more detailed explanation of DX11 tessellation can be found on the GeForce website.


Until we achieve something akin to the Star Trek holodeck, gamers will continue to demand a higher sense of realism from their virtual environments. Flags that don't flutter from a gust and walls that don't crumble from a shotgun blast are dead giveaways of a faked world. PhysX represent NVIDIA's best effort to pull the wool over our eyes by providing environments, objects, and figures that respond dynamically to the actions of the player and the game's AI.

NVIDIA Adaptive VSync

Vertical Synchronization, or VSync, is a known prescription for screen-tearing when an application's frame rates exceed the refresh rate of your monitor. We all know there's no such thing as a free lunch, and previous users of VSync suffered from stuttering due to the locked frame rate. Just as it sounds, Adaptive Vsync can selectively enable and disable the VSync frame rate lock, eliminating any sharp dips in performance while still preventing screen-tearing.

TXAA Anti-Aliasing

Anti-aliasing is particularly important for makers of CG films and game engines to ensure that the audience isn't distracted by jagged edges. Sophisticated filters enable to TXAA work to smooth these edges out at a level comparable to 4x the previous generation MSAA Anti-Aliasing. You also won't notice any jagged lines crawling in front of a slow-moving camera thanks to TXAA taking a "jitter" sample.

did you miss something? hell yah!
remember how 9800gt is a c2d era card?
now compare gtx 650ti to it on an [email protected] and we have something of a GPU upgrade advise here.

I see where you are coming from, but most games today are exceedingly GPU-dependent, and you could possibly make the argument that the upgrade would be even more pronounced because the GPU would make up a greater percentage of the overall "horsepower" assuming the C2D doesn't create a blatant bottleneck. Of course if it did, you're point is very pertinent because the upgrade would require a new chipset.

Thanks for the input and perspective!

another thing to keep in mind is that 9800gt is only 512mb and is not a 1080p GPU and therefore should not be tested at higher than 1050p resolutions.
that and use quad or c2d OCed cpu to pit it against gtx 650ti for more accurate comparison results.
