GeForce GTX 460 (OEM) vs Radeon R9 390 8G
Intro
The GeForce GTX 460 (OEM) comes with a core clock speed of 650 MHz and a GDDR5 memory frequency of 850 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 336 SPUs, 56 Texture Address Units, and 32 ROPs.Compare those specs to the Radeon R9 390 8G, which comes with a clock frequency of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 512-bit bus, and uses a 28 nm design. It is comprised of 2560 SPUs, 160 TAUs, and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 can be processed in one second. This figure is calculated 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 - the lower the bandwidth is, the lower the potential to get to the max fill rate.
