VS

GeForce GTX 860M vs Radeon R7 250X 2GB

Intro

The GeForce GTX 860M has clock speeds of 797 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 memory. It features 1152 SPUs along with 96 TAUs and 16 ROPs.

Compare all that to the Radeon R7 250X 2GB, which features a core clock frequency of 1000 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 860M 45 Watts
Radeon R7 250X 2GB 95 Watts
Difference: 50 Watts (111%)

Memory Bandwidth

As far as performance goes, the Radeon R7 250X 2GB should in theory be a little bit better than the GeForce GTX 860M in general. (explain)

Radeon R7 250X 2GB 72000 MB/sec
GeForce GTX 860M 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The GeForce GTX 860M is much (about 91%) better at AF than the Radeon R7 250X 2GB. (explain)

GeForce GTX 860M 76512 Mtexels/sec
Radeon R7 250X 2GB 40000 Mtexels/sec
Difference: 36512 (91%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 250X 2GB is a better choice, and very much so. (explain)

Radeon R7 250X 2GB 16000 Mpixels/sec
GeForce GTX 860M 12752 Mpixels/sec
Difference: 3248 (25%)

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 max amount of data (in units of MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
