GeForce GTX 1630 vs GeForce GTX 950

Intro

The GeForce GTX 1630 makes use of a 12 nm design. nVidia has set the core frequency at 1740 MHz. The GDDR6 RAM works at a frequency of 1500 MHz on this specific card. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 950, which comes with a clock frequency of 1024 MHz and a GDDR5 memory frequency of 1652 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 768 SPUs, 48 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
