GeForce GTX 650 Ti Review: Nvidia's Last Graphics Card For 2012
By , Igor Wallossek

Fluid Operations

The performance delta between the GeForce GTX 650 Ti and the GTX 660 is very slim indeed. Stepping up the GTX 660 Ti and the 670 yields a much bigger boost. Indeed, the lower-end model wins out over its bigger sibling in this discipline thanks to a higher clock rate.

Interestingly, the factory-overclocked GeForce GTX 650 Ti shows no such improvement. Only the pricier cards with more shader processors appear to benefit from higher frequencies.

Wave Simulation

Wave simulations also aren't the GeForce GTX 650 Ti’s forte, regardless of clock rate. Actually, the extra frequency does surprisingly little to help performance.

Julia Rendering

Julia fractal rendering allows the Kepler architecture shine a bit, and all three GeForce GTX 650 Ti models are able to squeeze in between the Fermi-based GeForce GTX 580 and 570.

Mandelbulb Rendering

Whereas the Julia fractal test looked pretty bleak for Nvidia, the situation flips when it comes to Mandelbulb rendering. Within the GeForce portfolio, Nvidia’s newest release is not only able to beat the Fermi-based cards, but the factory-overclocked variants also take on the lower-clocked OEM version of the GeForce GTX 660. Meanwhile, AMD can’t come anywhere near the GeForces cards' performance
