GeForce GTX 650 Ti 2GB vs Radeon R9 380 4G

Intro

Compare all that to the Radeon R9 380 4G, which uses a 28 nm design. AMD has set the core frequency at 970 MHz. The GDDR5 RAM works at a speed of 1425 MHz on this particular card. It features 1792 SPUs as well as 112 TAUs and 32 Rasterization Operator Units.

GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 96000 (111%)

Texel Rate

The Radeon R9 380 4G will be much (about 83%) more effective at anisotropic filtering than the GeForce GTX 650 Ti 2GB. (explain)

Radeon R9 380 4G		108640 Mtexels/sec
GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 49248 (83%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 380 4G is a better choice, and very much so. (explain)

Radeon R9 380 4G		31040 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 16192 (109%)

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 max amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the 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 maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
