Radeon HD 3470 256MB vs Radeon R7 240

Intro

The Radeon HD 3470 256MB uses a 55 nm design. AMD has clocked the core speed at 800 MHz. The DDR2 RAM is set to run at a frequency of 950 MHz on this specific model. It features 40(8x5) SPUs along with 4 TAUs and 4 Rasterization Operator Units.

Compare those specs to the Radeon R7 240, which makes use of a 28 nm design. AMD has clocked the core frequency at 730 MHz. The DDR3 RAM runs at a speed of 900 MHz on this particular card. It features 320 SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 3470 256MB should theoretically perform just a bit faster than the Radeon R7 240 overall. (explain)

Radeon HD 3470 256MB 30400 MB/sec
Radeon R7 240 28800 MB/sec
Difference: 1600 (6%)

Texel Rate

The Radeon R7 240 is much (approximately 356%) more effective at anisotropic filtering than the Radeon HD 3470 256MB. (explain)

Radeon R7 240 14600 Mtexels/sec
Radeon HD 3470 256MB 3200 Mtexels/sec
Difference: 11400 (356%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 240 is a better choice, by a large margin. (explain)

Radeon R7 240 5840 Mpixels/sec
Radeon HD 3470 256MB 3200 Mpixels/sec
Difference: 2640 (83%)

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 (in units of MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
