GeForce GT 315 vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which makes use of a 28 nm design. AMD has set the core speed at 715 MHz. The DDR3 RAM runs at a speed of 1000 MHz on this specific card. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 315 is 58% quicker than the Radeon R7 M260 overall, due to its greater data rate. (explain)

GeForce GT 315		25280 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 9280 (58%)

Texel Rate

The Radeon R7 M260 is much (approximately 72%) faster with regards to texture filtering than the GeForce GT 315. (explain)

Radeon R7 M260		17160 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 7160 (72%)

Pixel Rate

The Radeon R7 M260 will be a small bit (more or less 14%) better at AA than the GeForce GT 315, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon R7 M260		5720 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 720 (14%)

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 max amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that can be 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 video card will be at 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 that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
