GeForce GTX 465 vs Radeon R9 M375X

Intro

The GeForce GTX 465 has a clock frequency of 607 MHz and a GDDR5 memory frequency of 802 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It features 352 SPUs, 44 TAUs, and 32 ROPs.

Compare those specs to the Radeon R9 M375X, which has a GPU core clock speed of 1015 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 465 should in theory be much superior to the Radeon R9 M375X in general. (explain)

GeForce GTX 465 102592 MB/sec
Radeon R9 M375X 72000 MB/sec
Difference: 30592 (42%)

Texel Rate

The Radeon R9 M375X is a lot (approximately 52%) more effective at AF than the GeForce GTX 465. (explain)

Radeon R9 M375X 40600 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 13892 (52%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 465 is the winner, though not by far. (explain)

GeForce GTX 465 19424 Mpixels/sec
Radeon R9 M375X 16240 Mpixels/sec
Difference: 3184 (20%)

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 (counted in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
