GeForce GTX 965M vs Radeon R7 250X 2GB

Intro

The GeForce GTX 965M features clock speeds of 944 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

Compare those specifications to the Radeon R7 250X 2GB, which makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory works at a speed of 1125 MHz on this card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 965M 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The GeForce GTX 965M should be much (more or less 51%) faster with regards to texture filtering than the Radeon R7 250X 2GB. (explain)

GeForce GTX 965M 60416 Mtexels/sec
Radeon R7 250X 2GB 40000 Mtexels/sec
Difference: 20416 (51%)

Pixel Rate

The GeForce GTX 965M is quite a bit (approximately 89%) faster with regards to AA than the Radeon R7 250X 2GB, and also should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 965M 30208 Mpixels/sec
Radeon R7 250X 2GB 16000 Mpixels/sec
Difference: 14208 (89%)

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 maximum amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most 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 calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
