Radeon R7 240 vs Radeon R9 M380

Intro

Compare all of that to the Radeon R9 M380, which uses a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM is set to run at a speed of 1500 MHz on this particular card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M380 should perform quite a bit faster than the Radeon R7 240 in general. (explain)

Radeon R9 M380		96000 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 67200 (233%)

Texel Rate

The Radeon R9 M380 is a lot (about 174%) faster with regards to AF than the Radeon R7 240. (explain)

Radeon R9 M380		40000 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 25400 (174%)

Pixel Rate

The Radeon R9 M380 is much (approximately 174%) better at full screen anti-aliasing than the Radeon R7 240, and also will be able to handle higher resolutions while still performing well. (explain)

Radeon R9 M380		16000 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 10160 (174%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
