In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 Ti EVGA Classified Kingpin Edition are significantly better than the AMD Radeon HD 6990 Gigabyte 4GB Edition.

The GTX 780 Ti has a 242 MHz higher core clock speed and 48 more Texture Mapping Units than the HD 6990. This results in the GTX 780 Ti providing 97.9 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 GTX 780 Ti has a 242 MHz higher core clock speed than the HD 6990, but the HD 6990 has 16 more Render Output Units than the GTX 780 Ti. As a result, the HD 6990 exhibits a 1.6 GPixel/s better Pixel Fill Rate than the GTX 780 Ti. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 780 Ti was released over a year more recently than the HD 6990, and so the GTX 780 Ti is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6990.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The HD 6990 has 1024 MB more video memory than the GTX 780 Ti, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GTX 780 Ti has 16 GB/sec greater memory bandwidth than the HD 6990, which means that the memory performance of the GTX 780 Ti is slightly better than the HD 6990.

The GeForce GTX 780 Ti EVGA Classified Kingpin Edition has 2880 Shader Processing Units and the Radeon HD 6990 Gigabyte 4GB Edition has 3072. However, the actual shader performance of the GTX 780 Ti is 3275 and the actual shader performance of the HD 6990 is 1275. The GTX 780 Ti having 2000 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 780 Ti delivers a massively smoother and more efficient experience when processing graphical data than the HD 6990.

The GTX 780 Ti transistor size technology is 12 nm (nanometers) smaller than the HD 6990. This means that the GTX 780 Ti is expected to run slightly cooler and achieve higher clock frequencies than the HD 6990.

The GeForce GTX 780 Ti EVGA Classified Kingpin Edition requires 250 Watts to run but there is no entry for the Radeon HD 6990 Gigabyte 4GB Edition. We would recommend a PSU with at least 600 Watts for the GTX 780 Ti and a PSU with at least 750 Watts for the HD 6990. The HD 6990 has been recommended a PSU with 150 Watts more than the GTX 780 Ti. The difference is significant enough that the HD 6990 may have an adverse affect on your yearly electricity bills in comparison to the GTX 780 Ti.

GPU Mini Review

Mini ReviewGeForce GTX 780 Ti EVGA Classified Kingpin Edition is a special edition of the high-end GeForce GTX 780 Ti.
This edition comes with a custom double fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 780 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 875MHz to 1072MHz while its boost clock is now of 1137MHz. The memory clock was left untouched.
Benchmarks indicate a 10% performance boost when compared to the reference card and so this card surpasses the mighty GeForce GTX 690.
Radeon HD 6990 Gigabyte 4GB Edition is a renamed Radeon HD 6990 that features nothing new, not even a new cooling system and so its performance is exactly like the reference Radeon HD 6990.
