VS

Radeon HD 6570 (OEM) 2GB vs Radeon R9 M270X

Intro

The Radeon HD 6570 (OEM) 2GB uses a 40 nm design. AMD has clocked the core speed at 650 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this model. It features 480 SPUs along with 24 Texture Address Units and 8 ROPs.

Compare all that to the Radeon R9 M270X, which features GPU core speed of 725 MHz, and 2048 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M270X should theoretically be just a bit superior to the Radeon HD 6570 (OEM) 2GB in general. (explain)

Radeon R9 M270X 72000 MB/sec
Radeon HD 6570 (OEM) 2GB 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon R9 M270X will be quite a bit (approximately 86%) more effective at AF than the Radeon HD 6570 (OEM) 2GB. (explain)

Radeon R9 M270X 29000 Mtexels/sec
Radeon HD 6570 (OEM) 2GB 15600 Mtexels/sec
Difference: 13400 (86%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M270X is a better choice, and very much so. (explain)

Radeon R9 M270X 11600 Mpixels/sec
Radeon HD 6570 (OEM) 2GB 5200 Mpixels/sec
Difference: 6400 (123%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
