Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375 should theoretically be a small bit superior to the Radeon R7 M265 overall. (explain)

Radeon R9 M375		35200 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 3200 (10%)

Texel Rate

The Radeon R9 M375 will be quite a bit (approximately 133%) better at texture filtering than the Radeon R7 M265. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 23200 (133%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M375 is superior to the Radeon R7 M265, by a large margin. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 10440 (180%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
