Radeon HD 4890 1GB vs Radeon R7 370 4G
Intro
The Radeon HD 4890 1GB uses a 55 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory runs at a speed of 975 MHz on this specific model. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.Compare all that to the Radeon R7 370 4G, which comes with core speeds of 975 MHz on the GPU, and 1400 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
