Radeon HD 6570 (OEM) 1GB vs Radeon R7 240

Intro

Compare those specs to the Radeon R7 240, which makes use of a 28 nm design. AMD has set the core speed at 730 MHz. The DDR3 memory runs at a frequency of 900 MHz on this card. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon HD 6570 (OEM) 1GB should be a bit (approximately 7%) more effective at anisotropic filtering than the Radeon R7 240. (explain)

Radeon HD 6570 (OEM) 1GB		15600 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 1000 (7%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R7 240 is a better choice, but not by far. (explain)

Radeon R7 240		5840 Mpixels/sec
Radeon HD 6570 (OEM) 1GB		5200 Mpixels/sec
	Difference: 640 (12%)

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 (counted in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
