GeForce GTS 150 vs Radeon R7 M265

Intro

The GeForce GTS 150 comes with a core clock frequency of 740 MHz and a GDDR3 memory frequency of 500 MHz. It also uses a 256-bit memory bus, and makes use of a 55 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 ROPs.

Compare those specifications to the Radeon R7 M265, which comes with a GPU core clock speed of 725 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The GeForce GTS 150 will be quite a bit (more or less 172%) better at texture 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, by a large margin. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
