Compare any two graphics cards:
GeForce 9800 GT 1GB vs Radeon HD 4750
IntroThe GeForce 9800 GT 1GB features a GPU clock speed of 600 MHz, and the 1024 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also features 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the Radeon HD 4750, which makes use of a 40 nm design. AMD has clocked the core speed at 730 MHz. The GDDR5 RAM is set to run at a speed of 800 MHz on this card. It features 640(128x5) SPUs along with 32 Texture Address Units and 16 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 9800 GT 1GB will be 13% quicker than the Radeon HD 4750 overall, due to its greater data rate. (explain)
Texel RateThe GeForce 9800 GT 1GB should be quite a bit (more or less 44%) better at AF than the Radeon HD 4750. (explain)
Pixel RateThe Radeon HD 4750 is a lot (about 22%) faster with regards to FSAA than the GeForce 9800 GT 1GB, and will be able to handle higher resolutions without slowing down too much. (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 Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must 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 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 is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 bandwidth is, the lower the ability to reach the maximum fill rate.
