Compare any two graphics cards:
GeForce GT 450 (OEM) vs Radeon RX 460
IntroThe GeForce GT 450 (OEM) makes use of a 40 nm design. nVidia has clocked the core frequency at 790 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this specific model. It features 144 SPUs along with 24 Texture Address Units and 24 Rasterization Operator Units.
Compare those specifications to the Radeon RX 460, which features a core clock speed of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon RX 460 will be 17% faster than the GeForce GT 450 (OEM) overall, because of its higher bandwidth. (explain)
Texel RateThe Radeon RX 460 should be a lot (about 222%) better at AF than the GeForce GT 450 (OEM). (explain)
Pixel RateThe GeForce GT 450 (OEM) will be just a bit (approximately 9%) faster with regards to FSAA than the Radeon RX 460, and will be capable of handling higher screen 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 megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
