In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 770 SLI are noticeably better than the AMD Radeon R9 270X Crossfire.

The GTX 770 has a 46 MHz higher core clock speed and 96 more Texture Mapping Units than the R9 270X. This results in the GTX 770 providing 107.8 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 770 has a 46 MHz higher core clock speed than the R9 270X and the same number of Render Output Units. This results in the GTX 770 providing 2.9 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 R9 270X was released less than a year after the GTX 770, and so they are likely to have similar driver support for optimizing performance when running the latest games.

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 Radeon R9 270X Crossfire and the GeForce GTX 770 SLI have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 770 has 90.1 GB/sec greater memory bandwidth than the R9 270X, which means that the memory performance of the GTX 770 is massively better than the R9 270X.

The Radeon R9 270X Crossfire has 2560 Shader Processing Units and the GeForce GTX 770 SLI has 3072. However, the actual shader performance of the R9 270X is 2285 and the actual shader performance of the GTX 770 is 3333. The GTX 770 having 1048 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 770 delivers a massively smoother and more efficient experience when processing graphical data than the R9 270X.

The Radeon R9 270X Crossfire requires 360 Watts to run and the GeForce GTX 770 SLI requires 400 Watts. We would recommend a PSU with at least 750 Watts for the R9 270X and a PSU with at least 750 Watts for the GTX 770. The GTX 770 requires 40 Watts more than the R9 270X to run. The difference is significant enough that the GTX 770 may have a slight adverse affect on your yearly electricity bills in comparison to the R9 270X.

GPU Mini Review

Mini ReviewRadeon R9 270X Crossfire is a solution of two Radeon R9 270X put together using AMD'S Crossfire technology.
Check the page of Radeon R9 270X 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 up to x% better than a single Radeon R9 270X performing by itself but at times (depending whether or not the 3D game supports crossfire or in the graphics driver) it performed worse than a single Radeon R9 270X. Expect this combination to draw up to 360 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
GeForce GTX 770 SLI is a combination of 2 GeForce GTX 770 put together using NVIDIA's SLI technology.
Together, this combination offers 3072 Shader Processing Units, 256 TMUs and 64 ROPs. This, on a 256-bit memory interface, per card, of fast GDDR5. While the central unit runs at 1046MHz and goes up to 1085MHz, in Turbo Mode, the memory clock operates at 1752MHz.
Best case scenario, this combination performs better than dual-graphics GeForce GTX 690 but ultimately, its performance depends on the driver support and on the 3D application.
Therefore, and paired with a powerful processor, all demanding games are playable at the highest settings. Still, this combination might surpass the 450W barrier of TDP and so it will require a very powerful PSU.
