Compare any two graphics cards:
Radeon HD 6450 (OEM) vs Radeon R9 M265X
IntroThe Radeon HD 6450 (OEM) comes with a GPU core clock speed of 625 MHz, and the 512 MB of GDDR3 memory is set to run at 800 MHz through a 64-bit bus. It also is comprised of 160 Stream Processors, 8 TAUs, and 4 ROPs.Compare all that to the Radeon R9 M265X, which has a clock frequency of 575 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R9 M265X, in theory, should perform much faster than the Radeon HD 6450 (OEM) overall. (explain)
Texel RateThe Radeon R9 M265X will be quite a bit (more or less 360%) faster with regards to texture filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe Radeon R9 M265X is a lot (approximately 268%) better at FSAA than the Radeon HD 6450 (OEM), and also able to handle 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 get to the max fill rate.
