Radeon R7 M265 vs Radeon R9 M380

Intro

The Radeon R7 M265 comes with a core clock speed of 725 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Compare all of that to the Radeon R9 M380, which has core clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Radeon R9 M380 96000 MB/sec
Radeon R7 M265 32000 MB/sec
Difference: 64000 (200%)

Texel Rate

The Radeon R9 M380 should be quite a bit (more or less 130%) faster with regards to AF than the Radeon R7 M265. (explain)

Radeon R9 M380 40000 Mtexels/sec
Radeon R7 M265 17400 Mtexels/sec
Difference: 22600 (130%)

Pixel Rate

The Radeon R9 M380 will be a lot (more or less 176%) better at anti-aliasing than the Radeon R7 M265, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 M380 16000 Mpixels/sec
Radeon R7 M265 5800 Mpixels/sec
Difference: 10200 (176%)

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 data (in units of megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
