Radeon HD 4790 vs Radeon R7 360

Intro

Compare that to the Radeon R7 360, which features clock speeds of 1050 MHz on the GPU, and 1625 MHz on the 2048 MB of GDDR5 RAM. It features 768 SPUs as well as 48 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 360 should in theory be just a bit better than the Radeon HD 4790 in general. (explain)

Radeon R7 360		104000 MB/sec
Radeon HD 4790		102400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The Radeon R7 360 will be much (approximately 163%) better at anisotropic filtering than the Radeon HD 4790. (explain)

Radeon R7 360		50400 Mtexels/sec
Radeon HD 4790		19200 Mtexels/sec
	Difference: 31200 (163%)

Pixel Rate

The Radeon R7 360 will be a lot (more or less 75%) better at AA than the Radeon HD 4790, and also able to handle higher resolutions better. (explain)

Radeon R7 360		16800 Mpixels/sec
Radeon HD 4790		9600 Mpixels/sec
	Difference: 7200 (75%)

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 maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
