GeForce GTX 260 Core 216 vs Radeon R7 250X

Intro

Compare all that to the Radeon R7 250X, which uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this particular model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

	Difference: 39888 (55%)

Texel Rate

The GeForce GTX 260 Core 216 will be a small bit (approximately 4%) faster with regards to AF 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 will be just a bit (approximately 1%) faster with regards to full screen anti-aliasing than the Radeon R7 250X, and also will be able to handle higher resolutions while still performing well. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 can be processed in one second. This number is worked out by multiplying the total texture units of the card 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 in a 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 worked out by multiplying the number of ROPs by the the core speed of the card. 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
