GeForce 9500 GT 512MB GDDR3 vs Radeon HD 6570 (OEM) 2GB

Intro

Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which makes use of a 40 nm design. AMD has clocked the core speed at 650 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this particular card. 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

In theory, the Radeon HD 6570 (OEM) 2GB should be a lot faster than the GeForce 9500 GT 512MB GDDR3 overall. (explain)

Radeon HD 6570 (OEM) 2GB		64000 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 38400 (150%)

Texel Rate

The Radeon HD 6570 (OEM) 2GB is quite a bit (more or less 77%) better at AF than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon HD 6570 (OEM) 2GB		15600 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 6800 (77%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 6570 (OEM) 2GB is a better choice, not by a very large margin though. (explain)

Radeon HD 6570 (OEM) 2GB		5200 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
