GeForce 810M vs GeForce 840M

Intro

The GeForce 810M comes with a clock frequency of 738 MHz and a DDR3 memory speed of 900 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It is comprised of 48 SPUs, 8 Texture Address Units, and 4 ROPs.

Compare those specs to the GeForce 840M, which uses a 28 nm design. nVidia has set the core frequency at 1029 MHz. The DDR3 memory runs at a frequency of 1000 MHz on this specific card. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M 15 Watts
GeForce 840M 30 Watts
Difference: 15 Watts (100%)

Memory Bandwidth

In theory, the GeForce 840M should be a little bit faster than the GeForce 810M overall. (explain)

GeForce 840M 16000 MB/sec
GeForce 810M 14400 MB/sec
Difference: 1600 (11%)

Texel Rate

The GeForce 840M will be a lot (more or less 318%) better at texture filtering than the GeForce 810M. (explain)

GeForce 840M 24696 Mtexels/sec
GeForce 810M 5904 Mtexels/sec
Difference: 18792 (318%)

Pixel Rate

The GeForce 840M should be quite a bit (more or less 179%) faster with regards to AA than the GeForce 810M, and also will be capable of handling higher resolutions more effectively. (explain)

GeForce 840M 8232 Mpixels/sec
GeForce 810M 2952 Mpixels/sec
Difference: 5280 (179%)

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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
