Geforce GTX 770 vs Radeon R5 M330

Intro

The Geforce GTX 770 comes with a GPU core speed of 1046 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1753 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

Compare that to the Radeon R5 M330, which features clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 TAUs and 8 ROPs.

Radeon R5 M330 14400 MB/sec
Difference: 209984 (1458%)

Texel Rate

The Geforce GTX 770 should be much (more or less 550%) better at texture filtering than the Radeon R5 M330. (explain)

Geforce GTX 770 133888 Mtexels/sec
Radeon R5 M330 20600 Mtexels/sec
Difference: 113288 (550%)

Pixel Rate

The Geforce GTX 770 is much (approximately 306%) better at anti-aliasing than the Radeon R5 M330, and also able to handle higher screen resolutions more effectively. (explain)

Geforce GTX 770 33472 Mpixels/sec
Radeon R5 M330 8240 Mpixels/sec
Difference: 25232 (306%)

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 largest amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core clock 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 applied in one 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 number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
