GeForce GTS 150 vs Radeon R9 M265X

Intro

The GeForce GTS 150 comes with a clock speed of 740 MHz and a GDDR3 memory frequency of 500 MHz. It also features a 256-bit bus, and uses a 55 nm design. It is comprised of 128 SPUs, 64 Texture Address Units, and 16 ROPs.

Compare all of that to the Radeon R9 M265X, which has core speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M265X should in theory be much better than the GeForce GTS 150 in general. (explain)

Radeon R9 M265X 72000 MB/sec
GeForce GTS 150 32000 MB/sec
Difference: 40000 (125%)

Texel Rate

The GeForce GTS 150 should be quite a bit (approximately 106%) better at anisotropic filtering than the Radeon R9 M265X. (explain)

GeForce GTS 150 47360 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 24360 (106%)

Pixel Rate

The GeForce GTS 150 is quite a bit (about 29%) better at AA than the Radeon R9 M265X, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce GTS 150 11840 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 2640 (29%)

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 (measured in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
