Radeon HD 4350 vs Radeon R9 M295X

Intro

Compare all of that to the Radeon R9 M295X, which has GPU core speed of 750 MHz, and 4096 MB of GDDR5 RAM set to run at 1375 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 32 ROPs.

Radeon HD 4350		4600 Mtexels/sec
	Difference: 91400 (1987%)

Pixel Rate

The Radeon R9 M295X should be a lot (about 943%) faster with regards to anti-aliasing than the Radeon HD 4350, and also capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R9 M295X		24000 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 21700 (943%)

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 data (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 can be applied in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, 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 chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
