VS

GeForce GTS 150 vs Radeon R7 M265

Intro

The GeForce GTS 150 makes use of a 55 nm design. nVidia has clocked the core frequency at 740 MHz. The GDDR3 RAM is set to run at a speed of 500 MHz on this card. It features 128 SPUs as well as 64 TAUs and 16 ROPs.

Compare those specifications to the Radeon R7 M265, which uses a 28 nm design. AMD has clocked the core speed at 725 MHz. The DDR3 memory runs at a frequency of 1000 MHz on this specific card. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The GeForce GTS 150 is a lot (approximately 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

The GeForce GTS 150 should be a lot (more or less 104%) faster with regards to full screen anti-aliasing than the Radeon R7 M265, and also able to handle higher resolutions while still performing well. (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 largest amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
