In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 550 Ti DirectCU TOP Edition are massively better than the AMD Radeon X1900 Series.

The GTX 550 Ti was released over three years more recently than the Radeon X1900 Series, and so the GTX 550 Ti is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon X1900 Series when running the latest games.

The GTX 550 Ti has 768 MB more video memory than the Radeon X1900 Series, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 550 Ti also has superior memory performance overall.

The GTX 550 Ti has 34.5 GB/sec greater memory bandwidth than the Radeon X1900 Series, which means that the memory performance of the GTX 550 Ti is noticeably better than the Radeon X1900 Series.

The GeForce GTX 550 Ti DirectCU TOP Edition has 192 Shader Processing Units and the Radeon X1900 Series has 36. However, the actual shader performance of the GTX 550 Ti is 374 and the actual shader performance of the Radeon X1900 Series is 13. The GTX 550 Ti having 361 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 X1900 Series.

We would recommend a PSU with at least 520 Watts for the Radeon X1900 Series, but we do not have a recommended PSU wattage for the GTX 550 Ti.

GPU Mini Review

Mini ReviewGeForce GTX 550 Ti DirectCU TOP Edition is a special edition of the GeForce GTX 550 Ti. See the page of the standard version for more information.
The features include better cooling and an increase on the core-clock from 900MHz to 975MHz.
Benchmarks indicate the performance is 4.5% better when compared to the reference card.
Some modern demanding games will run at the highest settings using a 1080p resolution but the largest part will have to be played with a 720p resolution to be played optimally.
This Graphics Card needs to be paired with a decent Quad Core CPU.
Radeon X1900 Series is not a GPU but instead a combination between Radeon X1900 GT, Radeon X1900 XT and Radeon X1900 XTX whose rank is a balance between the three and that exists for System Requirements purposes only.
