GeForce GTX 650 vs Radeon R9 M380

Intro

The GeForce GTX 650 comes with clock speeds of 1058 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the Radeon R9 M380, which uses a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory is set to run at a frequency of 1500 MHz on this card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M380 should be 20% faster than the GeForce GTX 650 in general, because of its higher data rate. (explain)

Radeon R9 M380 96000 MB/sec
GeForce GTX 650 80000 MB/sec
Difference: 16000 (20%)

Texel Rate

The Radeon R9 M380 is a little bit (about 18%) faster with regards to texture filtering than the GeForce GTX 650. (explain)

Radeon R9 M380 40000 Mtexels/sec
GeForce GTX 650 33856 Mtexels/sec
Difference: 6144 (18%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 650 is the winner, though not by far. (explain)

GeForce GTX 650 16928 Mpixels/sec
Radeon R9 M380 16000 Mpixels/sec
Difference: 928 (6%)

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 information (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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 max fill rate.
