GeForce GT 420 vs Radeon R7 360

Intro

Compare that to the Radeon R7 360, which features a core clock speed of 1050 MHz and a GDDR5 memory speed of 1625 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is comprised of 768 SPUs, 48 TAUs, and 16 Raster Operation Units.

GeForce GT 420		50 Watts
Radeon R7 360		100 Watts
	Difference: 50 Watts (100%)

Memory Bandwidth

In theory, the Radeon R7 360 should perform quite a bit faster than the GeForce GT 420 in general. (explain)

Radeon R7 360		104000 MB/sec
GeForce GT 420		28800 MB/sec
	Difference: 75200 (261%)

Texel Rate

The Radeon R7 360 is quite a bit (about 800%) more effective at texture filtering than the GeForce GT 420. (explain)

Radeon R7 360		50400 Mtexels/sec
GeForce GT 420		5600 Mtexels/sec
	Difference: 44800 (800%)

Pixel Rate

The Radeon R7 360 should be much (approximately 500%) better at FSAA than the GeForce GT 420, and also will be able to handle higher resolutions better. (explain)

Radeon R7 360		16800 Mpixels/sec
GeForce GT 420		2800 Mpixels/sec
	Difference: 14000 (500%)

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 (in units of MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, 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 video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
