Compare any two graphics cards:
GeForce GT 230 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GT 230 has core clock speeds of 550 MHz on the GPU, and 800 MHz on the 1536 MB of DDR3 RAM. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which makes use of a 40 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory is set to run at a speed of 900 MHz on this particular card. It features 160 SPUs along with 8 TAUs and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GT 230 should in theory be quite a bit superior to the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GT 230 will be a lot (more or less 47%) better at anisotropic filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe GeForce GT 230 will be a lot (approximately 47%) faster with regards to anti-aliasing than the Radeon HD 6450 (OEM) 1GB, and should be capable of handling higher screen 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 Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, 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 maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
