GeForce 9500 GT DDR2 vs Radeon HD 6570 (OEM) 1GB

Intro

The GeForce 9500 GT DDR2 makes use of a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The DDR2 RAM is set to run at a frequency of 500 MHz on this specific card. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.

Compare all that to the Radeon HD 6570 (OEM) 1GB, which has clock speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 480 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon HD 6570 (OEM) 1GB, in theory, should be quite a bit faster than the GeForce 9500 GT DDR2 overall. (explain)

Radeon HD 6570 (OEM) 1GB 28800 MB/sec
GeForce 9500 GT DDR2 16000 MB/sec
Difference: 12800 (80%)

Texel Rate

The Radeon HD 6570 (OEM) 1GB should be much (more or less 77%) faster with regards to texture filtering than the GeForce 9500 GT DDR2. (explain)

Radeon HD 6570 (OEM) 1GB 15600 Mtexels/sec
GeForce 9500 GT DDR2 8800 Mtexels/sec
Difference: 6800 (77%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 6570 (OEM) 1GB is a better choice, though not by far. (explain)

Radeon HD 6570 (OEM) 1GB 5200 Mpixels/sec
GeForce 9500 GT DDR2 4400 Mpixels/sec
Difference: 800 (18%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
