Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs GeForce GT 430 (OEM)
IntroThe GeForce 8600 GT 512MB GDDR3 features a core clock speed of 540 MHz and a GDDR3 memory speed of 700 MHz. It also makes use of a 128-bit bus, and uses a 80 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.
Compare those specs to the GeForce GT 430 (OEM), which makes use of a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this specific model. It features 96 SPUs along with 16 Texture Address Units and 4 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GT 430 (OEM) should in theory be much faster than the GeForce 8600 GT 512MB GDDR3 overall. (explain)
Texel RateThe GeForce GT 430 (OEM) will be much (approximately 30%) better at anisotropic filtering than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce 8600 GT 512MB GDDR3 is a better choice, 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.
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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the 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 processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed 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 a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
