GeForce GTX 460 SE vs Radeon R7 250

Intro

Compare that to the Radeon R7 250, which features core speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Radeon R7 250		73600 MB/sec
	Difference: 35200 (48%)

Texel Rate

The GeForce GTX 460 SE will be quite a bit (about 30%) faster with regards to AF than the Radeon R7 250. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 7200 (30%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 460 SE is superior to the Radeon R7 250, and very much so. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 12800 (160%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 memory bandwidth is, the lower the potential to get to the max fill rate.
