GeForce GTX 465 vs Radeon RX 460

Intro

The GeForce GTX 465 uses a 40 nm design. nVidia has clocked the core speed at 607 MHz. The GDDR5 memory runs at a speed of 802 MHz on this specific model. It features 352 SPUs along with 44 TAUs and 32 Rasterization Operator Units.

Compare all of that to the Radeon RX 460, which comes with clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 75 Watts
GeForce GTX 465 200 Watts
Difference: 125 Watts (167%)

Memory Bandwidth

Performance-wise, the Radeon RX 460 should theoretically be a small bit superior to the GeForce GTX 465 in general. (explain)

Radeon RX 460 112000 MB/sec
GeForce GTX 465 102592 MB/sec
Difference: 9408 (9%)

Texel Rate

The Radeon RX 460 is a lot (approximately 129%) better at texture filtering than the GeForce GTX 465. (explain)

Radeon RX 460 61040 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 34332 (129%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 465 is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 465 19424 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 1984 (11%)

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 largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 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 can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
