GeForce GT 210 vs Radeon HD 6450 (OEM)

Intro

Compare those specifications to the Radeon HD 6450 (OEM), which features clock speeds of 625 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 160 SPUs as well as 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The Radeon HD 6450 (OEM) will be a bit (more or less 6%) faster with regards to AF than the GeForce GT 210. (explain)

Radeon HD 6450 (OEM)		5000 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 288 (6%)

Pixel Rate

The Radeon HD 6450 (OEM) will be a little bit (about 6%) faster with regards to full screen anti-aliasing than the GeForce GT 210, and able to handle higher screen resolutions without slowing down too much. (explain)

Radeon HD 6450 (OEM)		2500 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 144 (6%)

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 maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
