In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Ti are massively better than the AMD Radeon HD 3850 X3.

The GTX 660 Ti has a 246 MHz higher core clock speed and 64 more Texture Mapping Units than the HD 3850. This results in the GTX 660 Ti providing 70.4 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 660 Ti has a 246 MHz higher core clock speed than the HD 3850, but the HD 3850 has 24 more Render Output Units than the GTX 660 Ti. As a result, the HD 3850 exhibits a 10.1 GPixel/s better Pixel Fill Rate than the GTX 660 Ti. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 660 Ti was released over three years more recently than the HD 3850, and so the GTX 660 Ti is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 3850 when running the latest games.

The GTX 660 Ti has 512 MB more video memory than the HD 3850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 660 Ti also has superior memory performance overall.

The HD 3850 has 19 GB/sec greater memory bandwidth than the GTX 660 Ti, which means that the memory performance of the HD 3850 is slightly better than the GTX 660 Ti.

The Radeon HD 3850 X3 has 960 Shader Processing Units and the GeForce GTX 660 Ti has 1344. However, the actual shader performance of the HD 3850 is 642 and the actual shader performance of the GTX 660 Ti is 1317. The GTX 660 Ti having 675 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 Ti delivers a massively smoother and more efficient experience when processing graphical data than the HD 3850.

The GTX 660 Ti transistor size technology is 27 nm (nanometers) smaller than the HD 3850. This means that the GTX 660 Ti is expected to run slightly cooler and achieve higher clock frequencies than the HD 3850.

The Radeon HD 3850 X3 requires 145 Watts to run and the GeForce GTX 660 Ti requires 150 Watts. We would recommend a PSU with at least 450 Watts for the GTX 660 Ti, but we do not have a recommended PSU wattage for the HD 3850. The GTX 660 Ti requires 5 Watts more than the HD 3850 to run. The difference is not significant enough for the GTX 660 Ti to have a noticeably larger impact on your yearly electricity bills than the HD 3850.

GPU Mini Review

Mini ReviewRadeon HD 3850 X3 (not Crossfire) is a triple-graphics solution of three Radeon HD 3850.
This combination, also known as Radeon HD 3850 Trinity, is expected to offer almost the same performance as Radeon HD 3850 3-Way-Crossfired while consuming slightly less power. However, and just like Crossfire, its performance also relies a lot on proper driver support.
Some of today's modern demanding games might be playable using the high preset but most will require reduced settings. However, DirectX 11 games aren't supported.
GeForce GTX 660 Ti is a Performance Graphics Card based on the Kepler Architecture.

The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU. GPU
It equips a GPU GK104-300-KD-A2 which has 7 Stream Multiprocessors activated and thus offers 1344 Shader Processing Units, 112 TMUs and 24 ROPs. The Central Unit is initially clocked at 915MHz and goes up to 980MHz, in Turbo Mode.

The GPU accesses a 2GB frame buffer of fast GDDR5, through a 192-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1502MHz.

Power Consumption
With a rated board TDP of 150W, it requires at least a 450W PSU with two available 6-pin connectors.

At 1920x1080, the best suited resolution for GeForce GTX 660 Ti, benchmarks indicate its performance is a little over the older GeForce GTX 580.

System Suggestions
GeForce GTX 660 Ti is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.
