Radeon HD 5750 1GB vs Radeon R9 M265X

Intro

The Radeon HD 5750 1GB makes use of a 40 nm design. AMD has clocked the core frequency at 700 MHz. The GDDR5 RAM runs at a frequency of 1150 MHz on this particular model. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 ROPs.

Compare all that to the Radeon R9 M265X, which features GPU clock speed of 575 MHz, and 2048 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5750 1GB should be 2% quicker than the Radeon R9 M265X in general, because of its higher bandwidth. (explain)

Radeon HD 5750 1GB 73600 MB/sec
Radeon R9 M265X 72000 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon HD 5750 1GB is a small bit (about 10%) faster with regards to texture filtering than the Radeon R9 M265X. (explain)

Radeon HD 5750 1GB 25200 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 2200 (10%)

Pixel Rate

The Radeon HD 5750 1GB is much (approximately 22%) better at FSAA than the Radeon R9 M265X, and should be capable of handling higher screen resolutions better. (explain)

Radeon HD 5750 1GB 11200 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 2000 (22%)

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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher 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 one second.

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