Radeon R7 M260X vs Radeon R9 M265X

Intro

Compare those specifications to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has set the core frequency at 575 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M265X should in theory perform a little bit faster than the Radeon R7 M260X overall. (explain)

Radeon R9 M265X		72000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M265X should be just a bit (about 16%) faster with regards to texture filtering than the Radeon R7 M260X. (explain)

Radeon R9 M265X		23000 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 3200 (16%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M265X is the winner, and very much so. (explain)

Radeon R9 M265X		9200 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 2600 (39%)

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 data (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
