GeForce 9500 GT DDR2 vs Radeon HD 6570 (OEM) 2GB

Intro

The GeForce 9500 GT DDR2 uses a 65 nm design. nVidia has set the core frequency at 550 MHz. The DDR2 memory is set to run at a frequency of 500 MHz on this particular card. It features 32 SPUs as well as 16 TAUs and 8 ROPs.

Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which comes with a clock speed of 650 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It features 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Radeon HD 6570 (OEM) 2GB should in theory be much superior to the GeForce 9500 GT DDR2 overall. (explain)

Radeon HD 6570 (OEM) 2GB 64000 MB/sec
GeForce 9500 GT DDR2 16000 MB/sec
Difference: 48000 (300%)

Texel Rate

The Radeon HD 6570 (OEM) 2GB will be much (more or less 77%) faster with regards to AF than the GeForce 9500 GT DDR2. (explain)

Radeon HD 6570 (OEM) 2GB 15600 Mtexels/sec
GeForce 9500 GT DDR2 8800 Mtexels/sec
Difference: 6800 (77%)

Pixel Rate

The Radeon HD 6570 (OEM) 2GB will be a little bit (more or less 18%) better at AA than the GeForce 9500 GT DDR2, and also should be capable of handling higher resolutions more effectively. (explain)

Radeon HD 6570 (OEM) 2GB 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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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