Compare any two graphics cards:
GeForce 8800 GT 1GB vs GeForce GTX 650
IntroThe GeForce 8800 GT 1GB makes use of a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this particular card. It features 112 SPUs along with 56 TAUs and 16 ROPs.
Compare those specifications to the GeForce GTX 650, which makes use of a 28 nm design. nVidia has clocked the core speed at 1058 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this card. It features 384 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 650 should be 39% faster than the GeForce 8800 GT 1GB in general, because of its higher data rate. (explain)
Texel RateThe GeForce GTX 650 is a bit (approximately 1%) more effective at AF than the GeForce 8800 GT 1GB. (explain)
Pixel RateThe GeForce GTX 650 should be a lot (about 76%) more effective at full screen anti-aliasing than the GeForce 8800 GT 1GB, and also should be able to handle higher screen resolutions more effectively. (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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
