Compare any two graphics cards:
Radeon HD 4890 1GB vs Radeon R7 260X
IntroThe Radeon HD 4890 1GB makes use of a 55 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory is set to run at a speed of 975 MHz on this particular card. It features 800(160x5) SPUs along with 40 TAUs and 16 ROPs.Compare all of that to the Radeon R7 260X, which uses a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 memory works at a frequency of 1625 MHz on this specific model. It features 896 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4890 1GB, in theory, should perform a bit faster than the Radeon R7 260X overall. (explain)
Texel RateThe Radeon R7 260X will be a lot (approximately 54%) more effective at anisotropic filtering than the Radeon HD 4890 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R7 260X is superior to the Radeon HD 4890 1GB, though only just barely. (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 Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better 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 one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
