GeForce GT 210 vs Radeon HD 4650 1GB

Intro

Compare all of that to the Radeon HD 4650 1GB, which features GPU clock speed of 600 MHz, and 1024 MB of GDDR3 RAM set to run at 700 MHz through a 128-bit bus. It also is comprised of 320(64x5) SPUs, 32 TAUs, and 8 Raster Operation Units.

	Difference: 14488 (307%)

Pixel Rate

The Radeon HD 4650 1GB should be quite a bit (approximately 104%) more effective at full screen anti-aliasing than the GeForce GT 210, and also able to handle higher resolutions without slowing down too much. (explain)

Radeon HD 4650 1GB		4800 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 2444 (104%)

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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

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