Radeon HD 6450 (OEM) 1GB vs Radeon R9 M375

Intro

The Radeon HD 6450 (OEM) 1GB makes use of a 40 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM runs at a frequency of 900 MHz on this card. It features 160 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Compare those specs to the Radeon R9 M375, which has clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
