In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 550 Ti SLI are significantly better than the AMD Radeon R7 250X.

The Radeon R7 250X has a 50 MHz higher core clock speed than the GTX 550 Ti, but the GTX 550 Ti has 24 more Texture Mapping Units than the Radeon R7 250X. As a result, the GTX 550 Ti exhibits a 19.6 GTexel/s better Texture Fill Rate than the Radeon R7 250X. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon R7 250X has a 50 MHz higher core clock speed than the GTX 550 Ti, but the GTX 550 Ti has 32 more Render Output Units than the Radeon R7 250X. As a result, the GTX 550 Ti exhibits a 28 GPixel/s better Pixel Fill Rate than the Radeon R7 250X. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon R7 250X was released over a year more recently than the GTX 550 Ti, and so the Radeon R7 250X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 550 Ti.

The GeForce GTX 550 Ti SLI and the Radeon R7 250X have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 550 Ti has 124.8 GB/sec greater memory bandwidth than the Radeon R7 250X, which means that the memory performance of the GTX 550 Ti is massively better than the Radeon R7 250X.

The GeForce GTX 550 Ti SLI has 384 Shader Processing Units and the Radeon R7 250X has 640. However, the actual shader performance of the GTX 550 Ti is 691 and the actual shader performance of the Radeon R7 250X is 517. The GTX 550 Ti having 174 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 550 Ti delivers a massively smoother and more efficient experience when processing graphical data than the Radeon R7 250X.

The Radeon R7 250X transistor size technology is 12 nm (nanometers) smaller than the GTX 550 Ti. This means that the Radeon R7 250X is expected to run slightly cooler and achieve higher clock frequencies than the GTX 550 Ti.

The GeForce GTX 550 Ti SLI requires 250 Watts to run and the Radeon R7 250X requires 80 Watts. We would recommend a PSU with at least 600 Watts for the GTX 550 Ti and a PSU with at least 450 Watts for the Radeon R7 250X. The GTX 550 Ti requires 170 Watts more than the Radeon R7 250X to run. The difference is significant enough that the GTX 550 Ti may have an adverse affect on your yearly electricity bills in comparison to the Radeon R7 250X.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 550 Ti SLI is a solution of two GeForce GTX 550 Ti put together using NVIDIA's SLI Technology.

Architecture
The Fermi Architecture is manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

GPU
It consists of 2 GPUs Codenamed GF116-400-A1 which, together, offer 384 Shader Processing Units, 64 TMUs and 48 ROPs. The Central Unit is Clocked at 900MHz.

Memory
Each GPU accesses a 1GB frame buffer of fast GDDR5, through a 192-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1025MHz.

Power Consumption
Power Consumption lies between 225W and 250W.

Performance
Benchmarks Indicate GeForce GTX 550 Ti SLI's performance stands somewhere between GeForce GTX 560 Ti and GeForce GTX 570.

System Suggestions
GeForce GTX 550 Ti SLI is best suited for resolutions up to and including 1920x1080. We recommend a Very Strong Processor and 8GB of RAM for a system with GeForce GTX 550 Ti SLI.
Radeon R7 250X is a fast-middle-class Graphics Card based on the Graphics Core Next architecture. It offers the Cape Verde XT GPU.
The Cape Verde XT Core is a GCN 1.1 GPU and was first seen on Radeon HD 7770 and then re-used in the OEM only Radeon HD 8760.
It offers 640 Shader Processing Units, 40 TMUs and 16 ROPs, on a 128-bits memory interface of fast GDDR5.
Radeon R7 250X comes clocked at 950MHz (though there might be some 1GHz versions) and has its operating memory clock set at 1125MHz. The rated TDP board is of 80W and the release price around $99.
This card should come in 1GB and 2GB versions, though both will offer the same performance.
Its performance has proven to be exactly like Radeon HD 7770 GHz Edition (if clocked at 1GHz) and thus this card is not suited for 1080p gaming but it can handle 720p with ease. The 950MHz versions will be around 3% slower.
