VS

GeForce GTS 250 1GB vs GeForce GTX 965M

Intro

The GeForce GTS 250 1GB features core clock speeds of 738 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR3 RAM. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.

Compare all of that to the GeForce GTX 965M, which has core clock speeds of 944 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 memory. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 965M 60 Watts
GeForce GTS 250 1GB 145 Watts
Difference: 85 Watts (142%)

Memory Bandwidth

Theoretically speaking, the GeForce GTS 250 1GB is 10% quicker than the GeForce GTX 965M overall, because of its greater bandwidth. (explain)

GeForce GTS 250 1GB 70400 MB/sec
GeForce GTX 965M 64000 MB/sec
Difference: 6400 (10%)

Texel Rate

The GeForce GTX 965M should be a lot (more or less 28%) faster with regards to AF than the GeForce GTS 250 1GB. (explain)

GeForce GTX 965M 60416 Mtexels/sec
GeForce GTS 250 1GB 47232 Mtexels/sec
Difference: 13184 (28%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 965M is a better choice, and very much so. (explain)

GeForce GTX 965M 30208 Mpixels/sec
GeForce GTS 250 1GB 11808 Mpixels/sec
Difference: 18400 (156%)

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 MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, 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 most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. 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 quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
