VS

GeForce 810M vs GeForce 8500 GT

Intro

The GeForce 810M makes use of a 28 nm design. nVidia has clocked the core frequency at 738 MHz. The DDR3 RAM runs at a speed of 900 MHz on this specific model. It features 48 SPUs as well as 8 TAUs and 4 ROPs.

Compare that to the GeForce 8500 GT, which has core speeds of 450 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 memory. It features 16 SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M 15 Watts
GeForce 8500 GT 45 Watts
Difference: 30 Watts (200%)

Memory Bandwidth

Theoretically speaking, the GeForce 810M should perform just a bit faster than the GeForce 8500 GT in general. (explain)

GeForce 810M 14400 MB/sec
GeForce 8500 GT 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 810M is much (more or less 64%) more effective at texture filtering than the GeForce 8500 GT. (explain)

GeForce 810M 5904 Mtexels/sec
GeForce 8500 GT 3600 Mtexels/sec
Difference: 2304 (64%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 810M is a better choice, by far. (explain)

GeForce 810M 2952 Mpixels/sec
GeForce 8500 GT 1800 Mpixels/sec
Difference: 1152 (64%)

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 data (measured in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
