Radeon HD 6570 (OEM) 2GB vs Radeon R9 M275X

Intro

The Radeon HD 6570 (OEM) 2GB has a clock frequency of 650 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is comprised of 480 SPUs, 24 TAUs, and 8 ROPs.

Compare those specs to the Radeon R9 M275X, which features core speeds of 900 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

The Radeon R9 M275X will be a lot (about 131%) faster with regards to texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)

Radeon R9 M275X 36000 Mtexels/sec
Radeon HD 6570 (OEM) 2GB 15600 Mtexels/sec
Difference: 20400 (131%)

Pixel Rate

The Radeon R9 M275X should be quite a bit (approximately 177%) better at FSAA than the Radeon HD 6570 (OEM) 2GB, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 M275X 14400 Mpixels/sec
Radeon HD 6570 (OEM) 2GB 5200 Mpixels/sec
Difference: 9200 (177%)

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 maximum amount of information (counted in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
