Radeon R7 M260X vs Radeon R9 Fury X

Intro

Compare those specs to the Radeon R9 Fury X, which has a core clock frequency of 1050 MHz and a HBM memory frequency of 500 MHz. It also makes use of a 4096-bit bus, and uses a 28 nm design. It is comprised of 4096 SPUs, 256 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 Fury X, in theory, should be a lot faster than the Radeon R7 M260X in general. (explain)

Radeon R9 Fury X		512000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 448000 (700%)

Texel Rate

The Radeon R9 Fury X should be much (more or less 1258%) better at anisotropic filtering than the Radeon R7 M260X. (explain)

Radeon R9 Fury X		268800 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 249000 (1258%)

Pixel Rate

The Radeon R9 Fury X is quite a bit (approximately 918%) better at anti-aliasing than the Radeon R7 M260X, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 Fury X		67200 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 60600 (918%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
