HIS Radeon HD 5870 DiRT 2 Edition (H587F1GDG) vs HD 5870 iCooler V

Theoretical performance comparison

Each GPU has several important theoretical parameters that affect real-world game, 3D graphics and compute performance. They are pixel fillrate, texture 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)

27.2

Higher is better

Pixel fillrate number determines how many pixels a graphics card can draw on screen and off screen. The higher this number, the higher maximum display resolution and frame rate the GPU can support. There are two characteristics that influence the maximum theoretical pixel fillrate. These are graphics clock rate and the number of ROPs. Since both characteristics are equal between GPUs, their pixel fillrate is also identical.

- HIS Radeon HD 5870 iCooler V

Texture fill rate (gigatexels/s)

Higher is better

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

Single Precision performance (GFLOPS)

3000

2400

1800

1200

600

2720

Higher is better

Single Precision performance shows how many single-precision floating point operations the card can execute per second. The performance is expressed in billions of Floating Point Operations Per Second, or GFLOPS. Generally, the faster stream processors or CUDA cores run at, and the more cores / processors the graphics card has, the better Single Precision performance will be. These two cards have the same single-precision performance.

Double Precision performance (GFLOPS)

600

480

360

240

120

544

Higher is better

Like Single Precision performance, Double Precision one also provides the maximum number of floating-point operations, executed by stream processors or CUDA cores, but it refers to double precision (64-bit) operations. Both GPUs have the same performance.

Memory bandwidth (GB/s)

200

160

120

154

Higher is better

Memory bandwidth of graphics units is identical.
