In terms of overall gaming performance, the graphical capabilities of the AMD Radeon X1550 are massively better than the Nvidia Quadro4 550 XGL.

The Radeon X1550 was released over three years more recently than the Quadro4 550 XGL, and so the Radeon X1550 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Quadro4 550 XGL 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 X1550 has 192 MB more video memory than the Quadro4 550 XGL, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon X1550 also has superior memory performance overall.

The Radeon X1550 has 9.6 GB/sec greater memory bandwidth than the Quadro4 550 XGL, which means that the memory performance of the Radeon X1550 is marginally better than the Quadro4 550 XGL.

The Quadro4 550 XGL has 2 Shader Processing Units and the Radeon X1550 has 4. 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 X1550 requires 27 Watts to run but there is no entry for the Quadro4 550 XGL. We would recommend a PSU with at least 420 Watts for the Radeon X1550, but we do not have a recommended PSU wattage for the Quadro4 550 XGL.

GPU Mini Review

Mini ReviewQuadro4 550 XGL is a professional graphics card that will deliver similar gaming performance to GeForce4 MX 460, though worse due to the lack of support for gaming drivers, lower memory bandwidth and reduced frame buffer size, as well as a lower clocked central unit.Radeon X1550 is an entry-level GPU based on the 80nm variant of the R500 architecture.
It's based on the RV516 Core and offers 4 Pixel Shaders, 4 TMUs and 4 ROPs, on a 128-bit of standard DDR. The central unit runs at 550MHz and the memory clock operates at up to 400MHz.
It's therefore an underclocked Radeon X1300 PRO (although a 600MHz version is also available and will offer identical performance) with Crossfire support. As it's not based on a Shader-Unified architecture, both DirectX 10 & 11 games aren't supported.
