In terms of overall gaming performance, the graphical capabilities of the Nvidia Quadro 400 are significantly better than the AMD Radeon X1050.

The Quadro 400 was released over three years more recently than the Radeon X1050, and so the Quadro 400 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon X1050 when running the latest games.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The Quadro 400 has 384 MB more video memory than the Radeon X1050, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the Quadro 400 also has superior memory performance overall.

The Quadro 400 has 7.5 GB/sec greater memory bandwidth than the Radeon X1050, which means that the memory performance of the Quadro 400 is marginally better than the Radeon X1050.

The Quadro 400 has 48 Shader Processing Units and the Radeon X1050 has 4. However, the actual shader performance of the Quadro 400 is 22 and the actual shader performance of the Radeon X1050 is 1. The Quadro 400 having 21 better shader performance and an altogether better performance when taking into account other relevant data means that the Quadro 400 delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon X1050.

The Quadro 400 transistor size technology is 70 nm (nanometers) smaller than the Radeon X1050. This means that the Quadro 400 is expected to run massively cooler and achieve higher clock frequencies than the Radeon X1050. While they exhibit similar graphical performance, the Quadro 400 should consume less power than the Radeon X1050.

The Quadro 400 requires 32 Watts to run and the Radeon X1050 requires 24 Watts. We would recommend a PSU with at least 400 Watts for the Quadro 400 and a PSU with at least 300 Watts for the Radeon X1050. The Quadro 400 requires 8 Watts more than the Radeon X1050 to run. The difference is not significant enough for the Quadro 400 to have a noticeably larger impact on your yearly electricity bills than the Radeon X1050.
