Radeon HD 6570 (OEM) 2GB vs Radeon R9 M370X

Intro

Compare those specs to the Radeon R9 M370X, which features a clock speed of 800 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Theoretically, the Radeon R9 M370X should be just a bit faster than the Radeon HD 6570 (OEM) 2GB in general. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 6570 (OEM) 2GB		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M370X is much (more or less 105%) better at texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 6570 (OEM) 2GB		15600 Mtexels/sec
	Difference: 16400 (105%)

Pixel Rate

The Radeon R9 M370X will be quite a bit (about 146%) faster with regards to FSAA than the Radeon HD 6570 (OEM) 2GB, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 6570 (OEM) 2GB		5200 Mpixels/sec
	Difference: 7600 (146%)

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 past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
