GeForce GT 340 vs Radeon R7 M260

Intro

Compare all that to the Radeon R7 M260, which makes use of a 28 nm design. AMD has set the core frequency at 715 MHz. The DDR3 RAM works at a frequency of 1000 MHz on this specific model. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 340 should in theory perform much faster than the Radeon R7 M260 in general. (explain)

GeForce GT 340		54400 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 38400 (240%)

Texel Rate

The GeForce GT 340 is just a bit (approximately 3%) more effective at AF than the Radeon R7 M260. (explain)

GeForce GT 340		17600 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 440 (3%)

Pixel Rate

The Radeon R7 M260 is quite a bit (more or less 30%) better at full screen anti-aliasing than the GeForce GT 340, and also will be able to handle higher resolutions better. (explain)

Radeon R7 M260		5720 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 1320 (30%)

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 megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 reach the maximum fill rate.
