Compare any two graphics cards:
GeForce GTX 980M vs Radeon HD 4870 1GB
IntroThe GeForce GTX 980M uses a 28 nm design. nVidia has clocked the core frequency at 1038 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this specific card. It features 1536 SPUs along with 96 TAUs and 64 Rasterization Operator Units.Compare those specs to the Radeon HD 4870 1GB, which uses a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM is set to run at a frequency of 900 MHz on this specific card. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 980M should be a bit faster than the Radeon HD 4870 1GB in general. (explain)
Texel RateThe GeForce GTX 980M should be quite a bit (more or less 232%) better at AF than the Radeon HD 4870 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 980M is a better choice, by a large margin. (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 max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
