Radeon R7 250 vs Radeon R9 M370X

Intro

The Radeon R7 250 comes with core speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Compare those specs to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 250 should in theory perform a small bit faster than the Radeon R9 M370X in general. (explain)

Radeon R7 250 73600 MB/sec
Radeon R9 M370X 72000 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon R9 M370X is a lot (about 33%) more effective at AF than the Radeon R7 250. (explain)

Radeon R9 M370X 32000 Mtexels/sec
Radeon R7 250 24000 Mtexels/sec
Difference: 8000 (33%)

Pixel Rate

The Radeon R9 M370X should be much (more or less 60%) more effective at FSAA than the Radeon R7 250, and also able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R9 M370X 12800 Mpixels/sec
Radeon R7 250 8000 Mpixels/sec
Difference: 4800 (60%)

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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
