Radeon HD 7790 vs Radeon R7 360

Intro

The Radeon HD 7790 has a clock speed of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is made up of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Compare that to the Radeon R7 360, which makes use of a 28 nm design. AMD has clocked the core frequency at 1050 MHz. The GDDR5 memory works at a frequency of 1625 MHz on this specific card. It features 768 SPUs along with 48 Texture Address Units and 16 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling 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 video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
