Radeon HD 6570 (OEM) 1GB vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which comes with a core clock frequency of 1015 MHz and a DDR3 memory speed of 1100 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 should be quite a bit faster than the Radeon HD 6570 (OEM) 1GB overall. (explain)

Radeon R9 M375		35200 MB/sec
Radeon HD 6570 (OEM) 1GB		28800 MB/sec
	Difference: 6400 (22%)

Texel Rate

The Radeon R9 M375 should be much (more or less 160%) more effective at anisotropic filtering than the Radeon HD 6570 (OEM) 1GB. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon HD 6570 (OEM) 1GB		15600 Mtexels/sec
	Difference: 25000 (160%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M375 is superior to the Radeon HD 6570 (OEM) 1GB, and very much so. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon HD 6570 (OEM) 1GB		5200 Mpixels/sec
	Difference: 11040 (212%)

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 maximum amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
