GeForce GT 210 vs Radeon HD 4650 1GB

Intro

Compare all of that to the Radeon HD 4650 1GB, which has GPU clock speed of 600 MHz, and 1024 MB of GDDR3 memory running at 700 MHz through a 128-bit bus. It also is comprised of 320(64x5) Stream Processors, 32 TAUs, and 8 ROPs.

GeForce GT 210		12800 MB/sec
	Difference: 9600 (75%)

Texel Rate

The Radeon HD 4650 1GB should be much (approximately 307%) more effective at AF than the GeForce GT 210. (explain)

Radeon HD 4650 1GB		19200 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 14488 (307%)

Pixel Rate

The Radeon HD 4650 1GB will be quite a bit (approximately 104%) better at anti-aliasing than the GeForce GT 210, and also capable of handling higher screen 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 transported over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
