GeForce GT 340 1GB vs Radeon R9 380 4G
Intro
The GeForce GT 340 1GB uses a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this specific card. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.Compare all of that to the Radeon R9 380 4G, which has core speeds of 970 MHz on the GPU, and 1425 MHz on the 4096 MB of GDDR5 RAM. It features 1792 SPUs as well as 112 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 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 anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the 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 amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
