In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics Desktop (Sandy Bridge) are noticeably better than the Nvidia GeForce 8400 GS.

The Graphics Desktop has a 400 MHz higher core clock speed than the GeForce 8400 GS, but the GeForce 8400 GS has 7 more Texture Mapping Units than the Graphics Desktop. As a result, the GeForce 8400 GS exhibits a 2.7 GTexel/s better Texture Fill Rate than the Graphics Desktop. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Graphics Desktop has a 400 MHz higher core clock speed than the GeForce 8400 GS, but the GeForce 8400 GS has 3 more Render Output Units than the Graphics Desktop. As a result, the GeForce 8400 GS exhibits a 0.9 GPixel/s better Pixel Fill Rate than the Graphics Desktop. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Graphics Desktop was released over three years more recently than the GeForce 8400 GS, and so the Graphics Desktop is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 8400 GS 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 256 MB video memory, but the Graphics Desktop does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Graphics Desktop (Sandy Bridge) has 6 Shader Processing Units and the GeForce 8400 GS has 16. However, the actual shader performance of the Graphics Desktop is 24 and the actual shader performance of the GeForce 8400 GS is 18. The Graphics Desktop having 6 better shader performance and an altogether better performance when taking into account other relevant data means that the Graphics Desktop delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 8400 GS.

The Graphics Desktop transistor size technology is 58 nm (nanometers) smaller than the GeForce 8400 GS. This means that the Graphics Desktop is expected to run massively cooler and achieve higher clock frequencies than the GeForce 8400 GS. While they exhibit similar graphical performance, the Graphics Desktop should consume less power than the GeForce 8400 GS.

The HD Graphics Desktop (Sandy Bridge) requires 65 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 Graphics Desktop. The Graphics Desktop requires 47 Watts more than the GeForce 8400 GS to run. The difference is significant enough that the Graphics Desktop may have a slight adverse affect on your yearly electricity bills in comparison to the GeForce 8400 GS.

GPU Mini Review

Mini ReviewIntel HD Graphics Desktop (Sandy Bridge) are integrated graphics in the budget Celeron and Pentium Sandy Bridge Desktop processors.
Their performance depends on the processor they are integrated on, as the latter defines the Base and Boost Clock, as well as on the SYSTEM RAM, which defines the operating memory clock, and whether the GPU accesses a 64-bit or 128-bit memory interface.
More details to be added soon.
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.
