Compare any two graphics cards:
GeForce GTX 260 216SP 55 nm vs Radeon RX 460
IntroThe GeForce GTX 260 216SP 55 nm has a core clock frequency of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also features a 448-bit memory bus, and uses a 55 nm design. It features 216 SPUs, 72 Texture Address Units, and 28 ROPs.
Compare those specifications 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 runs at a speed of 1750 MHz on this specific card. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon RX 460 should be 0% faster than the GeForce GTX 260 216SP 55 nm in general, because of its higher data rate. (explain)
Texel RateThe Radeon RX 460 will be much (approximately 47%) more effective at texture filtering than the GeForce GTX 260 216SP 55 nm. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon RX 460 is the winner, but it probably won't make a huge difference. (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 information (measured in megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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 potential to reach the max fill rate.
