Compare any two graphics cards:
GeForce 9800 GT 1GB vs GeForce GT 450 (OEM)
IntroThe GeForce 9800 GT 1GB comes with core clock speeds of 600 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 112 SPUs along with 56 Texture Address Units and 16 ROPs.Compare all of that to the GeForce GT 450 (OEM), which has a clock frequency of 790 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 192-bit bus, and uses a 40 nm design. It features 144 SPUs, 24 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GT 450 (OEM) should theoretically be much superior to the GeForce 9800 GT 1GB in general. (explain)
Texel RateThe GeForce 9800 GT 1GB should be a lot (about 77%) more effective at texture filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GT 450 (OEM) is a better choice, by a large margin. (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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
