Testing and 3DMarks
Geforce 8400GS is currently the cheapest DirectX 10 card. The ATI HD 2400PRO might end up cheaper, but final price is not yet confirmed. Geforce 8400GS will have to fight that card in the low-end part of market. First results show that ATI is slower, but we will leave our conclusion to when HD 2400PRO comes out. Cheaper usually also means slower, and today we will see how slower the 8400GS really is when compared to a Geforce 8500GT.
Because of the already mentioned technical difficulties with our test monitor we couldn't do the tests on quality of multimedia content. This card is the one of the rare that can transfer both video and digital audio signal over DVI port. So you can get the entire multimedia content to your TV without additional audio cables.
In our standard test we have 3DMarks, while the game testing is done mostly without filters like Anisotropic Filter and Antialiasing. Geforce 8400GS is meant for multimedia and not gaming, but in spite of that you can play games, naturally on lower resolutions and with minimal settings.

In 3DMark 03 the card scores almost 6000 points, but it is still behind 8500GT by 2337 marks. The cards lack of power, caused by its 64bit memory interface, is mostly notable in Single Texturing and Pixel Shader 2.0 test.
All Geforce 8500 and 8600 cards have 128bit memory interface. Geforce 8500GT uses GDDR2, just like Geforce 8400GS, while Geforce 8600 cards come with GDDR3 memory. Geforce 8500GT is 39 per cent faster then Geforce 8400GS.

Geforce 8400GS did 3501 marks in 3DMark 05 test, which is 1224 points or 35 per cent lower then Geforce 8500GT. Zotac 8500GT, with core that is clocked at 700MHz, is 2624 marks or 75 per cent faster then Geforce 8400GS. Weakness of the test card is still shown in Single Texturing and Vertex Shader simple/complex test, and the main cause of all this, if we assumed correctly, is the 64 bit memory interface.
