GeForce 810M vs Radeon R9 M265X

Intro

Compare those specifications to the Radeon R9 M265X, which uses a 28 nm design. AMD has set the core frequency at 575 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M265X is 400% quicker than the GeForce 810M overall, because of its greater data rate. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon R9 M265X should be quite a bit (about 290%) faster with regards to anisotropic filtering than the GeForce 810M. (explain)

Radeon R9 M265X		23000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 17096 (290%)

Pixel Rate

The Radeon R9 M265X will be a lot (more or less 212%) faster with regards to AA than the GeForce 810M, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R9 M265X		9200 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 6248 (212%)

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 largest amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
