Compare any two graphics cards:
Radeon HD 4350 vs Radeon HD 5450
IntroThe Radeon HD 4350 comes with a core clock frequency of 575 MHz and a DDR2 memory speed of 500 MHz. It also makes use of a 64-bit memory bus, and makes use of a 55 nm design. It is comprised of 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.
Compare all that to the Radeon HD 5450, which makes use of a 40 nm design. ATi has set the core speed at 650 MHz. The DDR3 RAM is set to run at a frequency of 800 MHz on this specific card. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 5450 should in theory be quite a bit better than the Radeon HD 4350 in general. (explain)
Texel RateThe Radeon HD 5450 is a small bit (approximately 13%) more effective at AF than the Radeon HD 4350. (explain)
Pixel RateThe Radeon HD 5450 should be just a bit (approximately 13%) faster with regards to anti-aliasing than the Radeon HD 4350, and able to handle higher resolutions while still performing well. (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 maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at 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 could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
