GeForce GTS 150 vs Radeon R7 M265

Intro

The GeForce GTS 150 makes use of a 55 nm design. nVidia has set the core frequency at 740 MHz. The GDDR3 memory is set to run at a frequency of 500 MHz on this particular model. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Compare those specs to the Radeon R7 M265, which has a clock speed of 725 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce GTS 150 is much (about 172%) more effective at anisotropic filtering than the Radeon R7 M265. (explain)

GeForce GTS 150 47360 Mtexels/sec
Radeon R7 M265 17400 Mtexels/sec
Difference: 29960 (172%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTS 150 is the winner, and very much so. (explain)

GeForce GTS 150 11840 Mpixels/sec
Radeon R7 M265 5800 Mpixels/sec
Difference: 6040 (104%)

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.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units 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 processed 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 number is worked out by multiplying the number of Raster Operations Pipelines 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 is also dependant 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 maximum fill rate.
