AMD Radeon HD 8400 IGP vs ATI Radeon X550 64-bit

Theoretical performance comparison

Real-world game, 3D graphics and compute performance is dependent on several vital graphics card parameters, including texture fillrate, pixel fillrate, memory bandwidth, single- and double-precision performance. Why they are important and which GPU has better characteristics you will find below.

Pixel fill rate (gigapixels/s)

1.6

1.2

0.8

0.4

1.6

Higher is better

Pixel fillrate parameter shows how many pixels a graphics card can draw on screen and off screen. Higher numbers allow cards to support higher maximum display resolutions and frame rates. The maximum pixel fillrate depends on the number of Raster Operations Pipelines (ROPs) and graphics clock rate. Since both characteristics are equal between graphics cards, their pixel fillrate is also identical.

Texture fill rate (gigatexels/s)

3.2

Higher is better

Because two graphics cards operate at the same frequency, and the Radeon HD 8400 IGP has twice as many TMUs (Texture Mapping Units), it has higher texture fillrate. Better maximum texture fill rate means that the GPU can apply more textures and/or utilize more sophisticated 3D effects for each textured picture element, which improves games visual appearance.
