Radeon R7 240 vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which uses a 28 nm design. AMD has clocked the core speed at 1015 MHz. The DDR3 memory works at a frequency of 1100 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Radeon R7 240		14600 Mtexels/sec
	Difference: 26000 (178%)

Pixel Rate

The Radeon R9 M375 will be quite a bit (about 178%) more effective at full screen anti-aliasing than the Radeon R7 240, and will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 10400 (178%)

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 maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
