GeForce GTX 260 Core 216 vs Radeon R7 250X

Intro

Compare all of that to the Radeon R7 250X, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X		95 Watts
GeForce GTX 260 Core 216		202 Watts
	Difference: 107 Watts (113%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 260 Core 216 should in theory be quite a bit superior to the Radeon R7 250X in general. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 39888 (55%)

Texel Rate

The GeForce GTX 260 Core 216 will be a little bit (approximately 4%) more effective at anisotropic filtering than the Radeon R7 250X. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 1472 (4%)

Pixel Rate

The GeForce GTX 260 Core 216 should be a small bit (more or less 1%) faster with regards to FSAA than the Radeon R7 250X, and also will be able to handle higher resolutions more effectively. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 128 (1%)

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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the 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 number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also 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 of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
