Radeon HD 4350 vs Radeon R7 240

Intro

Compare all that to the Radeon R7 240, which comes with clock speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 Texture Address Units and 8 ROPs.

Memory Bandwidth

In theory, the Radeon R7 240 will be 260% faster than the Radeon HD 4350 in general, due to its greater data rate. (explain)

Radeon R7 240		28800 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 20800 (260%)

Texel Rate

The Radeon R7 240 is quite a bit (about 217%) faster with regards to anisotropic filtering than the Radeon HD 4350. (explain)

Radeon R7 240		14600 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 10000 (217%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R7 240 is superior to the Radeon HD 4350, by a large margin. (explain)

Radeon R7 240		5840 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 3540 (154%)

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 (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 are applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, 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 most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
