GeForce GTS 150 vs Radeon R7 M265

Intro

The GeForce GTS 150 has clock speeds of 740 MHz on the GPU, and 500 MHz on the 1024 MB of GDDR3 RAM. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Compare that to the Radeon R7 M265, which features GPU clock speed of 725 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 128-bit bus. It also features 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

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 will be quite a bit (about 172%) better 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 running with a high screen resolution is important to you, then the GeForce GTS 150 is superior to the Radeon R7 M265, by far. (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 maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed in one second. This figure 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
