GeForce GTS 250 1GB vs Radeon R9 M370X

Intro

Compare those specs to the Radeon R9 M370X, which has GPU core speed of 800 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M370X should perform a small bit faster than the GeForce GTS 250 1GB overall. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce GTS 250 1GB		70400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The GeForce GTS 250 1GB will be much (approximately 48%) faster with regards to anisotropic filtering than the Radeon R9 M370X. (explain)

GeForce GTS 250 1GB		47232 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 15232 (48%)

Pixel Rate

The Radeon R9 M370X should be just a bit (about 8%) faster with regards to AA than the GeForce GTS 250 1GB, and will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce GTS 250 1GB		11808 Mpixels/sec
	Difference: 992 (8%)

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 MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
