GeForce GT 450 (OEM) vs Radeon R9 380 2G
Intro
The GeForce GT 450 (OEM) has a GPU core clock speed of 790 MHz, and the 1536 MB of GDDR5 memory runs at 1000 MHz through a 192-bit bus. It also is comprised of 144 SPUs, 24 TAUs, and 24 ROPs.Compare those specifications to the Radeon R9 380 2G, which makes use of a 28 nm design. AMD has set the core speed at 970 MHz. The GDDR5 memory is set to run at a speed of 1425 MHz on this specific card. It features 1792 SPUs as well as 112 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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.
