GeForce GT 450 (OEM) vs Radeon R7 370 4G

Intro

Compare those specifications to the Radeon R7 370 4G, which comes with a GPU core clock speed of 975 MHz, and 4096 MB of GDDR5 RAM running at 1400 MHz through a 256-bit bus. It also is made up of 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

In theory, the Radeon R7 370 4G should be quite a bit faster than the GeForce GT 450 (OEM) in general. (explain)

Radeon R7 370 4G		179200 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 83200 (87%)

Texel Rate

The Radeon R7 370 4G is a lot (about 229%) more effective at texture filtering than the GeForce GT 450 (OEM). (explain)

Radeon R7 370 4G		62400 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 43440 (229%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 370 4G is the winner, and very much so. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 12240 (65%)

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 largest amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card 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 maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
