ATI Radeon X800 GT vs HIS Radeon X800 GT (HX80GTF256-3TOE)

Theoretical performance comparison

Real-world game, 3D graphics and compute performance depends on several card parameters, including texture fillrate, pixel fillrate, memory bandwidth, single-precision performance and double-precision performance. Below you will find why they are important, and which graphics card has better characteristics.

Pixel fill rate (gigapixels/s)

7.2

5.4

3.6

1.8

7.6

Higher is better

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

- ATI Radeon X800 GT

- HIS Radeon X800 GT

Texture fill rate (gigatexels/s)

3.8

Higher is better

Both models have the same number of Texture Mapping Units and the same graphics frequency, as a result their texture fillrate is equal.

Memory bandwidth (GB/s)

31.6

31.4

Higher is better

Memory bandwidth parameter specifies how much memory (in Gigabytes) the graphics card can read from or write to dedicated memory per second. GPUs with higher memory bandwidth have better performance at high display resolutions, or when using large and detailed textures, and/or utilizing complex 3D effects and filters, like anti-aliasing. The bandwidth is dependent on several components, such as memory type, speed, and width of memory interface. Specifically, the ATI Radeon X800 GT GPU has higher clocked memory. As such, it has more memory bandwidth.
