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

Intro

Compare all that to the Radeon R7 240, which makes use of a 28 nm design. AMD has set the core frequency at 730 MHz. The DDR3 RAM runs at a frequency of 900 MHz on this specific model. It features 320 SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

Memory Bandwidth

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

Texel Rate

The Radeon HD 6570 (OEM) 1GB should be a bit (approximately 7%) better at AF 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 running with lots of anti-aliasing is important to you, then the Radeon R7 240 is superior to the Radeon HD 6570 (OEM) 1GB, not by a very large margin though. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at 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 card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
