Radeon HD 4350 vs Radeon R7 250X

Intro

Compare all that to the Radeon R7 250X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Radeon HD 4350		8000 MB/sec
	Difference: 64000 (800%)

Texel Rate

The Radeon R7 250X should be much (approximately 770%) better at AF than the Radeon HD 4350. (explain)

Radeon R7 250X		40000 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 35400 (770%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 250X is a better choice, and very much so. (explain)

Radeon R7 250X		16000 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 13700 (596%)

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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core 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 also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
