GeForce GTS 250 1GB vs GeForce GTX 860M

Intro

The GeForce GTS 250 1GB uses a 65/55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 RAM runs at a frequency of 1100 MHz on this card. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the GeForce GTX 860M, which makes use of a 28 nm design. nVidia has clocked the core speed at 797 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular model. It features 1152 SPUs along with 96 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 860M 45 Watts
GeForce GTS 250 1GB 145 Watts
Difference: 100 Watts (222%)

Memory Bandwidth

As far as performance goes, the GeForce GTS 250 1GB should in theory be just a bit superior to the GeForce GTX 860M overall. (explain)

GeForce GTS 250 1GB 70400 MB/sec
GeForce GTX 860M 64000 MB/sec
Difference: 6400 (10%)

Texel Rate

The GeForce GTX 860M will be quite a bit (approximately 62%) more effective at anisotropic filtering than the GeForce GTS 250 1GB. (explain)

GeForce GTX 860M 76512 Mtexels/sec
GeForce GTS 250 1GB 47232 Mtexels/sec
Difference: 29280 (62%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 860M is the winner, but it probably won't make a huge difference. (explain)

GeForce GTX 860M 12752 Mpixels/sec
GeForce GTS 250 1GB 11808 Mpixels/sec
Difference: 944 (8%)

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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
