Compare any two graphics cards:
Radeon HD 3650 512MB vs Radeon HD 4650 1GB
IntroThe Radeon HD 3650 512MB features core clock speeds of 725 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 120(24x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.Compare those specifications to the Radeon HD 4650 1GB, which uses a 55 nm design. AMD has clocked the core speed at 600 MHz. The GDDR3 memory works at a speed of 700 MHz on this particular model. It features 320(64x5) SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 3650 512MB is 14% faster than the Radeon HD 4650 1GB overall, due to its greater data rate. (explain)
Texel RateThe Radeon HD 4650 1GB will be a lot (about 231%) more effective at anisotropic filtering than the Radeon HD 3650 512MB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 4650 1GB is the winner, and very much so. (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 maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
