GeForce GT 210 vs Radeon HD 6450 (OEM)

Intro

Compare those specifications to the Radeon HD 6450 (OEM), which makes use of a 40 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR3 RAM works at a frequency of 800 MHz on this specific model. It features 160 SPUs along with 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 theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon HD 6450 (OEM) is just a bit (approximately 6%) better at texture filtering than the GeForce GT 210. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 6450 (OEM) is the winner, though only just barely. (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 largest amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. It's worked out 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 it uses DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at 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 video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
