In terms of overall gaming performance, the graphical capabilities of the AMD Radeon X1600 are massively better than the Nvidia GeForce FX 5700.
The Radeon X1600 was released over three years more recently than the GeForce FX 5700, and so the Radeon X1600 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce FX 5700 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 X1600 has 256 MB more video memory than the GeForce FX 5700, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon X1600 also has superior memory performance overall.
The Radeon X1600 has 8.8 GB/sec greater memory bandwidth than the GeForce FX 5700, which means that the memory performance of the Radeon X1600 is marginally better than the GeForce FX 5700.
Both the GeForce FX 5700 and the Radeon X1600 have 4 Shader Processing Units. 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, we sadly do not have enough data in this area to complete the comparison.
The Radeon X1600 requires 27 Watts to run but there is no entry for the GeForce FX 5700. We would recommend a PSU with at least 350 Watts for the Radeon X1600, but we do not have a recommended PSU wattage for the GeForce FX 5700.
The top-to-bottom family of NVIDIA GeForce FX GPUs provide both high-performance gaming for enthusiasts and best-in-class features for mainstream users. Whether you're a bleeding-edge gamer who desires the most advanced gaming technology available, or a PC user in search of the perfect combination of power, performance, and value--GeForce FX solutions deliver.
Radeon X1600 is a middle-class GPU based on the 80nm variant of the R500 architecture.
It's based on the RV516 XT Core and offers 4 Pixel Shaders, 4 TMUs and 4 ROPs, on a 128-bit of standard DDR2. The central unit runs at 635MHz and the memory clock operates at up to 400MHz.
It's therefore a further clocked Radeon X1300 PRO/Radeon X1550 but should only perform slightly better although the 512MB frame buffer might prove useful in some of today's modern games. As it's not based on a Shader-Unified architecture, both DirectX 10 & 11 games aren't supported.
