ATI Radeon X800 GT vs HIS Radeon X800 GT IceQ (HX80GTQ128-1TOE)

Theoretical performance comparison

Real-world game, 3D graphics and compute performance is dependent on several GPU parameters, including texture fillrate, pixel fillrate, memory bandwidth, along with single- 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 card can draw on screen and off screen. The higher this number, the higher display resolution and frame rate the GPU can support. The maximum pixel fillrate is proportional to graphics clock speed and the number of ROPs. Since both characteristics are equal between GPUs, their pixel fillrate is also identical.

- HIS Radeon X800 GT IceQ

Texture fill rate (gigatexels/s)

3.8

Higher is better

Because two models have the same number of TMUs and the same graphics frequency, their texture fillrate is equal.

Memory bandwidth (GB/s)

31.6

22.4

Higher is better

To speed up processing, the cards store 3D scene data, textures and intermediate data, used for image generation, in on-board memory. The video memory usually has much higher bandwidth than system RAM, and more bandwidth allows the card to run at higher screen resolutions, use larger and more detailed textures, and apply more complex 3D effects and filters. The bandwidth depends on a few components, such as memory type, speed, and memory interface width. Specifically, the Radeon X800 GT graphics card offers better and higher clocked memory. As a consequence, it has higher memory bandwidth.
