Compare any two graphics cards:
Radeon R5 M330 vs Radeon R7 250
IntroThe Radeon R5 M330 comes with a clock speed of 1030 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It features 320 SPUs, 20 Texture Address Units, and 8 ROPs.Compare that to the Radeon R7 250, which has core speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R7 250 will be 411% quicker than the Radeon R5 M330 in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon R7 250 should be a little bit (about 17%) faster with regards to texture filtering than the Radeon R5 M330. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R5 M330 is superior to the Radeon R7 250, 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's interface 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, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the graphics card can 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 ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
