GeForce GTX 1070 Ti vs Geforce GTX 770

Intro

The GeForce GTX 1070 Ti comes with a core clock speed of 1607 MHz and a GDDR5 memory speed of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 16 nm design. It is comprised of 2432 SPUs, 152 TAUs, and 64 ROPs.

Compare those specifications to the Geforce GTX 770, which makes use of a 28 nm design. nVidia has set the core speed at 1046 MHz. The GDDR5 memory runs at a speed of 1753 MHz on this particular card. It features 1536 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
