Compare any two graphics cards:
GeForce 9800 GTX+ vs GeForce GTX 1050 3GB
IntroThe GeForce 9800 GTX+ uses a 55 nm design. nVidia has clocked the core speed at 738 MHz. The GDDR3 memory works at a speed of 1100 MHz on this particular card. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.
Compare all of that to the GeForce GTX 1050 3GB, which features a clock speed of 1392 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 96-bit bus, and uses a 14 nm design. It is comprised of 768 SPUs, 48 TAUs, and 24 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 1050 3GB, in theory, should perform much faster than the GeForce 9800 GTX+ in general. (explain)
Texel RateThe GeForce GTX 1050 3GB should be quite a bit (about 41%) faster with regards to texture filtering than the GeForce 9800 GTX+. (explain)
Pixel RateThe GeForce GTX 1050 3GB should be much (about 183%) more effective at anti-aliasing than the GeForce 9800 GTX+, and capable of handling higher screen resolutions while still performing well. (explain)
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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better 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 a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
