Radeon R7 240 vs Radeon R9 M295X

Intro

Compare all that to the Radeon R9 M295X, which comes with a core clock speed of 750 MHz and a GDDR5 memory speed of 1375 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth

The Radeon R9 M295X should in theory perform quite a bit faster than the Radeon R7 240 in general. (explain)

Radeon R9 M295X		176000 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 147200 (511%)

Texel Rate

The Radeon R9 M295X should be a lot (approximately 558%) more effective at anisotropic filtering than the Radeon R7 240. (explain)

Radeon R9 M295X		96000 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 81400 (558%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M295X is a better choice, by far. (explain)

Radeon R9 M295X		24000 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 18160 (311%)

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 (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). 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 reach the max fill rate.
