Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8400 GS are very slightly better than the AMD Radeon X1300 XT .
The GeForce 8400 GS was released less than a year after the X1300 XT, and so they are likely to have similar driver support for optimizing performance 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 Radeon X1300 XT and the GeForce 8400 GS have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The X1300 XT has 6.4 GB/sec greater memory bandwidth than the GeForce 8400 GS, which means that the memory performance of the X1300 XT is marginally better than the GeForce 8400 GS.
The Radeon X1300 XT has 12 Shader Processing Units and the GeForce 8400 GS has 16. However, the actual shader performance of the X1300 XT is 4 and the actual shader performance of the GeForce 8400 GS is 18. The GeForce 8400 GS having 14 better shader performance is not particularly notable, as altogether the X1300 XT performs better when taking into account other relevant data.
The Radeon X1300 XT requires 22 Watts to run and the GeForce 8400 GS requires 18 Watts. We would recommend a PSU with at least 300 Watts for the GeForce 8400 GS, but we do not have a recommended PSU wattage for the X1300 XT. The X1300 XT requires 4 Watts more than the GeForce 8400 GS to run. The difference is not significant enough for the X1300 XT to have a noticeably larger impact on your yearly electricity bills than the GeForce 8400 GS.
|Mini Review||Radeon X1300 XT is an entry-level GPU based on the 90nm variant of the R500 architecture. |
It's based on the RV530 Core and offers 12 Pixel Shaders, 4 TMUs and 4 ROPs, on a 128-bit of standard DDR2. The central unit runs at 500MHz and the memory clock operates at up to 400MHz.
Despite featuring more Pixel and Vertex Shaders, Radeon X1300 XT consumes less power than X1300 PRO due to being equipped with energy efficient DDR2 (against DDR X1300 PRO) and featuring a lower clocked central unit.
Still, its performance is quite limited and so today's modern games are only playable at the lowest settings or unplayable at all. As it's not based on a Shader-Unified architecture, both DirectX 10 & 11 games aren't supported.
|GeForce 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.
