Radeon HD 7750 vs Radeon R9 M365X

Intro

The Radeon HD 7750 features a GPU core clock speed of 800 MHz, and the 1024 MB of GDDR5 memory is set to run at 1125 MHz through a 128-bit bus. It also is made up of 512 SPUs, 32 TAUs, and 16 ROPs.

Compare those specs to the Radeon R9 M365X, which features GPU core speed of 925 MHz, and 4096 MB of GDDR5 RAM running 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

Both cards have exactly the same memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon R9 M365X is much (approximately 45%) better at anisotropic filtering than the Radeon HD 7750. (explain)

Radeon R9 M365X 37000 Mtexels/sec
Radeon HD 7750 25600 Mtexels/sec
Difference: 11400 (45%)

Pixel Rate

The Radeon R9 M365X is just a bit (approximately 16%) faster with regards to FSAA than the Radeon HD 7750, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 M365X 14800 Mpixels/sec
Radeon HD 7750 12800 Mpixels/sec
Difference: 2000 (16%)

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: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This 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 graphics 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 can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
