Compare any two graphics cards:
GeForce 9600 GSO 1.5GB vs Radeon RX 470 4GB
IntroThe GeForce 9600 GSO 1.5GB comes with clock speeds of 550 MHz on the GPU, and 800 MHz on the 1536 MB of GDDR3 RAM. It features 96 SPUs as well as 48 Texture Address Units and 12 Rasterization Operator Units.
Compare all of that to the Radeon RX 470 4GB, which uses a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 memory runs at a frequency of 1650 MHz on this model. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon RX 470 4GB should perform a lot faster than the GeForce 9600 GSO 1.5GB in general. (explain)
Texel RateThe Radeon RX 470 4GB should be quite a bit (approximately 349%) better at texture filtering than the GeForce 9600 GSO 1.5GB. (explain)
Pixel RateThe Radeon RX 470 4GB should be much (about 349%) better at anti-aliasing than the GeForce 9600 GSO 1.5GB, and will be able to handle higher screen resolutions more effectively. (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 max amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to 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 potential to reach the max fill rate.
