GeForce GTX 260 Core 216 vs Radeon R9 M380

Intro

Compare all of that to the Radeon R9 M380, which comes with GPU clock speed of 1000 MHz, and 4096 MB of GDDR5 RAM set to run at 1500 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 260 Core 216 should theoretically perform a little bit faster than the Radeon R9 M380 in general. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 15888 (17%)

Texel Rate

The GeForce GTX 260 Core 216 should be a little bit (more or less 4%) faster with regards to AF than the Radeon R9 M380. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 1472 (4%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 260 Core 216 is a better choice, but only just. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 128 (1%)

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 max amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
