Geforce GTX 770 vs Radeon RX 590

Intro

The Geforce GTX 770 features a clock speed of 1046 MHz and a GDDR5 memory speed of 1753 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is made up of 1536 SPUs, 128 TAUs, and 32 ROPs.

Compare those specs to the Radeon RX 590, which makes use of a 12 nm design. AMD has set the core frequency at 1469 MHz. The GDDR5 memory runs at a speed of 2000 MHz on this specific card. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.

Theoretically speaking, the Radeon RX 590 should be 17% quicker than the Geforce GTX 770 overall, due to its higher bandwidth. (explain)

Radeon RX 590 262144 MB/sec
Geforce GTX 770 224384 MB/sec
Difference: 37760 (17%)

Texel Rate

The Radeon RX 590 should be quite a bit (approximately 58%) more effective at anisotropic filtering than the Geforce GTX 770. (explain)

Radeon RX 590 211536 Mtexels/sec
Geforce GTX 770 133888 Mtexels/sec
Difference: 77648 (58%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 590 is the winner, by a large margin. (explain)

Radeon RX 590 47008 Mpixels/sec
Geforce GTX 770 33472 Mpixels/sec
Difference: 13536 (40%)

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 (measured in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
