Radeon R9 M290X vs Radeon R9 M295X

Intro

Compare all that to the Radeon R9 M295X, which makes use of a 28 nm design. AMD has set the core speed at 750 MHz. The GDDR5 memory is set to run at a speed of 1375 MHz on this card. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Radeon R9 M290X		153600 MB/sec
	Difference: 22400 (15%)

Texel Rate

The Radeon R9 M295X should be quite a bit (approximately 41%) better at AF than the Radeon R9 M290X. (explain)

Radeon R9 M295X		96000 Mtexels/sec
Radeon R9 M290X		68000 Mtexels/sec
	Difference: 28000 (41%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M290X is superior to the Radeon R9 M295X, but not by far. (explain)

Radeon R9 M290X		27200 Mpixels/sec
Radeon R9 M295X		24000 Mpixels/sec
	Difference: 3200 (13%)

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 (measured in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
