In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8400 GS are massively better than the AMD Radeon 9250.

The GeForce 8400 GS was released over three years more recently than the Radeon 9250, and so the GeForce 8400 GS is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon 9250 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 GeForce 8400 GS has 128 MB more video memory than the Radeon 9250, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce 8400 GS also has superior memory performance overall.

The GeForce 8400 GS has 3.2 GB/sec greater memory bandwidth than the Radeon 9250, which means that the memory performance of the GeForce 8400 GS is marginally better than the Radeon 9250.

The GeForce 8400 GS has 16 Shader Processing Units and the Radeon 9250 has 4. However, the actual shader performance of the GeForce 8400 GS is 18 and the actual shader performance of the Radeon 9250 is 1. The GeForce 8400 GS having 17 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 8400 GS delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon 9250.

The GeForce 8400 GS requires 18 Watts to run but there is no entry for the Radeon 9250. We would recommend a PSU with at least 300 Watts for the GeForce 8400 GS.

GPU Mini Review

Mini ReviewGeForce 8400 GS is an entry-level GFX based on the 80nm variant of the first-shader unified architecture.
It's based on the G86 Core and offers 16 Shader Processing Units, 8 TMUs and 4 ROPs, on a 64-bit memory interface of DDR2. The central unit runs at 450MHz and the memory clock operates at 400MHz. It will consume no more than 40 Watt.
It's therefore a GeForce 8500 GT, slightly lower power consumption and no SLI support.
This GPU is only suited for a 1024x768 (or less) resolution. Most of today's games will only run at low settings and extremely demanding games might not run at all. DirectX 11 based games aren't supported and its performance will decrease drastically, as the resolution increases.
Note: This GPU had two revisions which added HDMI support, DDR3 memory and different core configurations.
The Radeon R200 is the second generation of Radeon graphics chips from ATI Technologies. The architecture features 3D acceleration based upon Microsoft Direct3D 8.0 and OpenGL 1.3, a major improvement in features and performance compared to the preceding Radeon R100 design. The GPU also includes 2D GUI acceleration, video acceleration, and multiple display outputs. 'R200' refers to the development codename of the initially released GPU of the generation. It is the basis for a variety of other succeeding products.
