GeForce GTS 250 1GB vs GeForce GTX 860M

Intro

The GeForce GTS 250 1GB uses a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 RAM works at a speed of 1100 MHz on this specific model. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Compare those specs to the GeForce GTX 860M, which makes use of a 28 nm design. nVidia has set the core frequency at 797 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this specific model. It features 1152 SPUs as well as 96 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few 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.
