GeForce GTX 1070 Ti vs GeForce GTX 650 Ti 2GB

Intro

The GeForce GTX 1070 Ti uses a 16 nm design. nVidia has clocked the core frequency at 1607 MHz. The GDDR5 memory is set to run at a speed of 2000 MHz on this specific card. It features 2432 SPUs as well as 152 Texture Address Units and 64 Rasterization Operator Units.

Compare those specs to the GeForce GTX 650 Ti 2GB, which features GPU clock speed of 928 MHz, and 2048 MB of GDDR5 memory set to run at 1350 MHz through a 128-bit bus. It also features 768 SPUs, 64 TAUs, and 16 Raster Operation Units.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
