Compare any two graphics cards:
GeForce GT 450 (OEM) vs Radeon RX 460
IntroThe GeForce GT 450 (OEM) comes with a GPU core clock speed of 790 MHz, and the 1536 MB of GDDR5 RAM runs at 1000 MHz through a 192-bit bus. It also is made up of 144 Stream Processors, 24 Texture Address Units, and 24 ROPs.
Compare all of that to the Radeon RX 460, which makes use of a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this specific card. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon RX 460 should perform just a bit faster than the GeForce GT 450 (OEM) in general. (explain)
Texel RateThe Radeon RX 460 is much (about 222%) better at texture filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateThe GeForce GT 450 (OEM) is a bit (approximately 9%) better at anti-aliasing than the Radeon RX 460, and also should be capable of handling higher screen resolutions better. (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 maximum amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the 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 number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
