VS

Radeon HD 6570 (OEM) 1GB vs Radeon R7 240

Intro

The Radeon HD 6570 (OEM) 1GB makes use of a 40 nm design. AMD has clocked the core speed at 650 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this card. It features 480 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Compare those specs to the Radeon R7 240, which features a clock frequency of 730 MHz and a DDR3 memory frequency of 900 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It features 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240 30 Watts
Radeon HD 6570 (OEM) 1GB 50 Watts
Difference: 20 Watts (67%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon HD 6570 (OEM) 1GB is a small bit (more or less 7%) faster with regards to AF than the Radeon R7 240. (explain)

Radeon HD 6570 (OEM) 1GB 15600 Mtexels/sec
Radeon R7 240 14600 Mtexels/sec
Difference: 1000 (7%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 240 is the winner, but only just. (explain)

Radeon R7 240 5840 Mpixels/sec
Radeon HD 6570 (OEM) 1GB 5200 Mpixels/sec
Difference: 640 (12%)

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: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics 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 most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
