In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6990 Crossfire are noticeably better than the Nvidia GeForce GTX 760 Ti (OEM).

The GTX 760 Ti has a 85 MHz higher core clock speed than the HD 6990, but the HD 6990 has 272 more Texture Mapping Units than the GTX 760 Ti. As a result, the HD 6990 exhibits a 216.2 GTexel/s better Texture Fill Rate than the GTX 760 Ti. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 760 Ti has a 85 MHz higher core clock speed than the HD 6990, but the HD 6990 has 96 more Render Output Units than the GTX 760 Ti. As a result, the HD 6990 exhibits a 76.9 GPixel/s better Pixel Fill Rate than the GTX 760 Ti. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 760 Ti was released over a year more recently than the HD 6990, and so the GTX 760 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 6144 MB more video memory than the GTX 760 Ti, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 6990 also has superior memory performance overall.

The HD 6990 has 447.7 GB/sec greater memory bandwidth than the GTX 760 Ti, which means that the memory performance of the HD 6990 is massively better than the GTX 760 Ti.

The GeForce GTX 760 Ti (OEM) has 1344 Shader Processing Units and the Radeon HD 6990 Crossfire has 6144. However, the actual shader performance of the GTX 760 Ti is 1317 and the actual shader performance of the HD 6990 is 5100. The HD 6990 having 3783 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 6990 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 760 Ti.

The GTX 760 Ti transistor size technology is 12 nm (nanometers) smaller than the HD 6990. This means that the GTX 760 Ti is expected to run slightly cooler and achieve higher clock frequencies than the HD 6990.

The GeForce GTX 760 Ti (OEM) requires 170 Watts to run and the Radeon HD 6990 Crossfire requires 750 Watts. We would recommend a PSU with at least 500 Watts for the GTX 760 Ti and a PSU with at least 1000 Watts for the HD 6990. The HD 6990 requires 580 Watts more than the GTX 760 Ti to run. The difference is significant enough that the HD 6990 may have an adverse affect on your yearly electricity bills in comparison to the GTX 760 Ti.

GPU Mini Review

Mini ReviewGeForce GTX 760 Ti (OEM) is an OEM only high-end Graphics Card based on the Kepler GK104 (325-A2 Variant) core of the Kepler Architecture.
The 325-A2 Variant of the Kepler GK104 Core offers 1344 Shader Processing Units, 112 TMUs and 32 ROPs, on a 256-bit memory interface. While the central unit runs at 915MHz and goes up to 980MHz, in Turbo Mode, the memory clock operates at 1502MHz.
It's therefore a renamed GeForce GTX 670 and will offer exactly the same performance.
Radeon HD 6990 Crossfire is a solution of two Radeon HD 6990 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 6990 to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is only up to 10% better than a single Radeon HD 6990 performing by itself but it might be worse (depending on whether or not the 3D game supports crossfire or in the graphics driver) than a single Radeon HD 6990. Expect this combination to draw up to 750 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
