In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 are significantly better than the Nvidia GeForce GTX 660 3GB (OEM).
The GeForce GTX 780 has a 40 MHz higher core clock speed and 96 more Texture Mapping Units than the GTX 660. This results in the GeForce GTX 780 providing 86.7 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.
The GeForce GTX 780 has a 40 MHz higher core clock speed and 24 more Render Output Units than the GTX 660. This results in the GeForce GTX 780 providing 21.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The GeForce GTX 780 was released less than a year after the GTX 660, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The GeForce GTX 660 3GB (OEM) and the GeForce GTX 780 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The GeForce GTX 780 has 154 GB/sec greater memory bandwidth than the GTX 660, which means that the memory performance of the GeForce GTX 780 is massively better than the GTX 660.
The GeForce GTX 660 3GB (OEM) has 1152 Shader Processing Units and the GeForce GTX 780 has 2304. However, the actual shader performance of the GTX 660 is 1023 and the actual shader performance of the GeForce GTX 780 is 2078. The GeForce GTX 780 having 1055 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 780 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 660.
The GeForce GTX 660 3GB (OEM) requires 130 Watts to run and the GeForce GTX 780 requires 250 Watts. We would recommend a PSU with at least 450 Watts for the GTX 660 and a PSU with at least 600 Watts for the GeForce GTX 780. The GeForce GTX 780 requires 120 Watts more than the GTX 660 to run. The difference is significant enough that the GeForce GTX 780 may have an adverse affect on your yearly electricity bills in comparison to the GTX 660.

| Mini Review | GeForce GTX 660 3GB (OEM) is a high-end Graphics Card based on the 28nm, Kepler architecture. It offers the GK104-200-KD-A2 GPU which features 1152 Shader Processing Units, 96 TMUs and 24 ROPs, on a 192-bit memory interface of fast GDDR5. While the central unit runs at 823MHz and goes up to 888MHz, in turbo mode, the memory clock operates at 1400MHz. When compared to the 1.5GB version, the frame buffer was doubled to 3GB though this will not boost its performance and can be addressed as a gimmick - marketing to lure consumers into paying more for the same product. It is an OEM card that despite the core differences, performs similar to the retail version. | GeForce GTX 780 is a high-end graphics-card based on the 28nm, Kepler architecture. It's based on the Kepler GK110 Core (same used on Titan) but with 12 SMX activated and therefore offers 2304 Shader Processing Units, 192 TMUs and 48 ROPs on a 384-bit memory interface of fast GDDR5. While the central unit runs at 863MHz and goes up to 902MHz in Turbo, the memory clock operates at 1502MHz. It consumes up to 250W. Benchmarks indicate that its performance is up to 30% better than previous GeForce GTX 680 and thus allows even the most demanding games to be playable at the highest settings, at 1080p. With proper overclocking and cooling, it can surpass GeForce GTX Titan. | |||
