Radeon HD 6950 vs Radeon R7 370 4G

Intro

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

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 370 4G is superior to the Radeon HD 6950, and very much so. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
Radeon HD 6950		25600 Mpixels/sec
	Difference: 5600 (22%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If 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 texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core 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 quite a few 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.
