Radeon HD 6870 vs Radeon R7 360

Intro

Compare all that to the Radeon R7 360, which comes with a GPU core clock speed of 1050 MHz, and 2048 MB of GDDR5 memory set to run at 1625 MHz through a 128-bit bus. It also features 768 Stream Processors, 48 Texture Address Units, and 16 ROPs.

3DMark Fire Strike Graphics Score

Radeon R7 360		4110 points
Radeon HD 6870		2870 points
	Difference: 1240 (43%)

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 360		100 Watts
Radeon HD 6870		151 Watts
	Difference: 51 Watts (51%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6870 should perform quite a bit faster than the Radeon R7 360 overall. (explain)

Radeon HD 6870		134400 MB/sec
Radeon R7 360		104000 MB/sec
	Difference: 30400 (29%)

Texel Rate

Both cards have exactly the same texel fill rate, so in theory they should be equally good at at anisotropic filtering. (explain)

Pixel Rate

The Radeon HD 6870 is much (more or less 71%) faster with regards to FSAA than the Radeon R7 360, and also should be able to handle higher resolutions without slowing down too much. (explain)

Radeon HD 6870		28800 Mpixels/sec
Radeon R7 360		16800 Mpixels/sec
	Difference: 12000 (71%)

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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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