GeForce GT 210 vs Radeon HD 6450 (OEM)

Intro

Compare those specs to the Radeon HD 6450 (OEM), which uses a 40 nm design. AMD has set the core speed at 625 MHz. The GDDR3 RAM runs at a speed of 800 MHz on this model. It features 160 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

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

Texel Rate

The Radeon HD 6450 (OEM) will be a small bit (more or less 6%) more effective at 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) should be a bit (more or less 6%) more effective at FSAA than the GeForce GT 210, and should be able to handle higher resolutions better. (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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
