Radeon HD 6570 (OEM) 2GB vs Radeon R7 M260X

Intro

Compare those specs to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific card. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R7 M260X is much (approximately 27%) faster with regards to anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)

Radeon R7 M260X		19800 Mtexels/sec
Radeon HD 6570 (OEM) 2GB		15600 Mtexels/sec
	Difference: 4200 (27%)

Pixel Rate

The Radeon R7 M260X will be a lot (more or less 27%) faster with regards to full screen anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R7 M260X		6600 Mpixels/sec
Radeon HD 6570 (OEM) 2GB		5200 Mpixels/sec
	Difference: 1400 (27%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
