Compare any two graphics cards:
Radeon HD 4350 vs Radeon HD 5450
IntroThe Radeon HD 4350 features core clock speeds of 575 MHz on the GPU, and 500 MHz on the 512 MB of DDR2 RAM. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.
Compare that to the Radeon HD 5450, which has clock speeds of 650 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 RAM. It features 80(16x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 5450 should in theory be quite a bit faster than the Radeon HD 4350 in general. (explain)
Texel RateThe Radeon HD 5450 should be a bit (approximately 13%) faster with regards to AF than the Radeon HD 4350. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 5450 is superior to the Radeon HD 4350, though only just barely. (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: Bandwidth is the max amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 can be applied in one second. This 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
