Compare any two graphics cards:
GeForce 8300 GS (OEM) vs GeForce GT 210
IntroThe GeForce 8300 GS (OEM) makes use of a 80 nm design. nVidia has clocked the core frequency at 450 MHz. The DDR2 memory works at a speed of 400 MHz on this particular card. It features 8 SPUs along with 4 Texture Address Units and 2 ROPs.
Compare those specifications to the GeForce GT 210, which features a core clock speed of 589 MHz and a DDR3 memory frequency of 800 MHz. It also makes use of a 64-bit memory bus, and makes use of a 40 nm design. It is comprised of 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GT 210 should in theory perform much faster than the GeForce 8300 GS (OEM) in general. (explain)
Texel RateThe GeForce GT 210 is much (approximately 162%) faster with regards to AF than the GeForce 8300 GS (OEM). (explain)
Pixel RateThe GeForce GT 210 should be quite a bit (more or less 162%) faster with regards to FSAA than the GeForce 8300 GS (OEM), and also able to handle higher screen resolutions better. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling 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 can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs 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 is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
