GeForce GTX 650 Ti 2GB vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory works at a speed of 1125 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 27392 (86%)

Pixel Rate

The GeForce GTX 650 Ti 2GB is a small bit (about 16%) more effective at anti-aliasing than the Radeon R9 M370X, and also capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 2048 (16%)

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 (measured in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
