Radeon R7 370 4G vs Radeon R9 270

Intro

Compare all of that to the Radeon R9 270, which uses a 28 nm design. AMD has set the core frequency at 900 MHz. The GDDR5 memory works at a frequency of 1400 MHz on this particular card. It features 1280 SPUs as well as 80 Texture Address Units and 32 ROPs.

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The Radeon R9 270 is a small bit (about 15%) better at texture filtering than the Radeon R7 370 4G. (explain)

Radeon R9 270		72000 Mtexels/sec
Radeon R7 370 4G		62400 Mtexels/sec
	Difference: 9600 (15%)

Pixel Rate

The Radeon R7 370 4G will be a small bit (more or less 8%) more effective at AA than the Radeon R9 270, and also will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
Radeon R9 270		28800 Mpixels/sec
	Difference: 2400 (8%)

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: Bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to 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 reach the maximum fill rate.
