GeForce GTX 650 Ti vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which features core speeds of 800 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 Ti should perform a small bit faster than the Radeon R9 M370X in general. (explain)

GeForce GTX 650 Ti		86400 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 650 Ti is quite a bit (about 86%) faster with regards to AF than the Radeon R9 M370X. (explain)

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

Pixel Rate

The GeForce GTX 650 Ti should be a little bit (approximately 16%) more effective at full screen anti-aliasing than the Radeon R9 M370X, and also will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 650 Ti		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 max amount of data (measured in megabytes per second) that can be transferred 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 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
