In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 4290 are marginally better than the Nvidia GeForce 8400 GS.

The Radeon HD 4290 has a 250 MHz higher core clock speed than the GeForce 8400 GS, but the GeForce 8400 GS has 4 more Texture Mapping Units than the Radeon HD 4290. As a result, the GeForce 8400 GS exhibits a 0.8 GTexel/s better Texture Fill Rate than the Radeon HD 4290. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon HD 4290 has a 250 MHz higher core clock speed than the GeForce 8400 GS and the same number of Render Output Units. This results in the Radeon HD 4290 providing 1 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon HD 4290 was released over a year more recently than the GeForce 8400 GS, and so the Radeon HD 4290 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 8400 GS.

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 HD 4290, 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 6.4 GB/sec greater memory bandwidth than the Radeon HD 4290, which means that the memory performance of the GeForce 8400 GS is marginally better than the Radeon HD 4290.

The GeForce 8400 GS has 16 Shader Processing Units and the Radeon HD 4290 has 40. The two GPUs are based on different architectures, but deliver an equivalent shader performance. To compare, we must continue to look at the memory bandwidth, Texture and Pixel Rates. In this case, the GeForce 8400 GS has 0.8 GTexel/s better Texture Fill Rate and 6.4 GB/sec greater memory bandwidth, but the Radeon HD 4290 has 1 GPixel/s better Pixel Fill Rate. Although the GPUs are very similar in performance, the GeForce 8400 GS takes the edge.

The Radeon HD 4290 transistor size technology is 25 nm (nanometers) smaller than the GeForce 8400 GS. This means that the Radeon HD 4290 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce 8400 GS. While they exhibit similar graphical performance, the Radeon HD 4290 should consume less power than the GeForce 8400 GS.

The GeForce 8400 GS requires 18 Watts to run but there is no entry for the Radeon HD 4290. 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.
Radeon HD 4290 (IGP) is an integrated GPU on the AMD 890GX Chipset.
It's based on the RS880D Core and offers 40 Shader Processing Units, 4 TMUs and 4 ROPs a 32-bit memory interface of either DDR2 (more commonly) or DDR3. The central unit runs, commonly, at up to 700MHz and the memory clock's operating speed depends on the system RAM's speed.
Radeon HD 4290's performance depends on the users system configuration which will define the operating memory clock's speed and on the desktop manufacturer which decides its central unit's speed.
Therefore, Radeon HD 4290, even if paired with DDR3 won't offer similar performance to the dedicated Radeon HD 4350. DirectX 11 games aren't supported.
