Compare any two graphics cards:
GeForce GT 430 (OEM) vs GeForce GTX 275
IntroThe GeForce GT 430 (OEM) features a core clock frequency of 700 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 16 Texture Address Units, and 4 ROPs.
Compare all that to the GeForce GTX 275, which comes with clock speeds of 633 MHz on the GPU, and 1134 MHz on the 896 MB of GDDR3 memory. It features 240 SPUs as well as 80 Texture Address Units and 28 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 275 should in theory be quite a bit faster than the GeForce GT 430 (OEM) in general. (explain)
Texel RateThe GeForce GTX 275 should be quite a bit (about 352%) faster with regards to anisotropic filtering than the GeForce GT 430 (OEM). (explain)
Pixel RateThe GeForce GTX 275 should be quite a bit (about 533%) more effective at full screen anti-aliasing than the GeForce GT 430 (OEM), and also able to handle higher 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.
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 maximum amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
