GeForce GTX 950 vs Radeon R9 M380

Intro

Compare that to the Radeon R9 M380, which features core speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 950 should in theory be a small bit superior to the Radeon R9 M380 overall. (explain)

GeForce GTX 950		105728 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 9728 (10%)

Texel Rate

The GeForce GTX 950 is quite a bit (more or less 23%) better at texture filtering than the Radeon R9 M380. (explain)

GeForce GTX 950		49152 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 9152 (23%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 950 is superior to the Radeon R9 M380, and very much so. (explain)

GeForce GTX 950		32768 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 16768 (105%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total 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 maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
