Compare any two graphics cards:
GeForce GT 430 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GT 430 features a GPU clock speed of 700 MHz, and the 512 MB of GDDR3 RAM runs at 900 MHz through a 128-bit bus. It also is comprised of 96 SPUs, 16 Texture Address Units, and 4 ROPs.
Compare all of that to the Radeon HD 6450 (OEM) 1GB, which features core speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 160 SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Both cards have exactly the same bandwidth, so theoretically they should perform the same. (explain)
Texel RateThe GeForce GT 430 is a lot (more or less 87%) faster with regards to AF than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 6450 (OEM) 1GB is superior to the GeForce GT 430, but only just. (explain)
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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
