Compare any two graphics cards:
GeForce 8800 GT 1GB vs Radeon R9 M375X
IntroThe GeForce 8800 GT 1GB uses a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 memory works at a speed of 900 MHz on this particular model. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.
Compare those specifications to the Radeon R9 M375X, which uses a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Performance-wise, the Radeon R9 M375X should in theory be quite a bit superior to the GeForce 8800 GT 1GB overall. (explain)
Texel RateThe Radeon R9 M375X should be a lot (approximately 21%) better at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)
Pixel RateThe Radeon R9 M375X is a lot (about 69%) faster with regards to AA than the GeForce 8800 GT 1GB, and should be capable of handling 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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 bandwidth is, the lower the ability to reach the maximum fill rate.
