GeForce GTX 660 vs Radeon R7 370 4G

Intro

The GeForce GTX 660 makes use of a 28 nm design. nVidia has clocked the core speed at 980 MHz. The GDDR5 RAM is set to run at a speed of 1502 MHz on this model. It features 960 SPUs as well as 80 Texture Address Units and 24 Rasterization Operator Units.

Compare all that to the Radeon R7 370 4G, which uses a 28 nm design. AMD has clocked the core speed at 975 MHz. The GDDR5 RAM is set to run at a frequency of 1400 MHz on this particular card. It features 1024 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
