GeForce GTX 465 vs Radeon R9 M380

Intro

The GeForce GTX 465 comes with clock speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 memory. It features 352 SPUs as well as 44 Texture Address Units and 32 ROPs.

Compare those specifications to the Radeon R9 M380, which uses a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 465 is 7% quicker than the Radeon R9 M380 in general, due to its greater data rate. (explain)

GeForce GTX 465 102592 MB/sec
Radeon R9 M380 96000 MB/sec
Difference: 6592 (7%)

Texel Rate

The Radeon R9 M380 is quite a bit (more or less 50%) more effective at texture filtering than the GeForce GTX 465. (explain)

Radeon R9 M380 40000 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 13292 (50%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 465 is the winner, and very much so. (explain)

GeForce GTX 465 19424 Mpixels/sec
Radeon R9 M380 16000 Mpixels/sec
Difference: 3424 (21%)

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 information (counted in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
