Compare any two graphics cards:
GeForce 9600 GSO 768MB vs Radeon RX 470 4GB
IntroThe GeForce 9600 GSO 768MB features core clock speeds of 550 MHz on the GPU, and 800 MHz on the 768 MB of GDDR3 memory. It features 96 SPUs as well as 48 TAUs and 12 Rasterization Operator Units.
Compare all of that to the Radeon RX 470 4GB, which makes use of a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 RAM works at a speed of 1650 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon RX 470 4GB should in theory be quite a bit better than the GeForce 9600 GSO 768MB overall. (explain)
Texel RateThe Radeon RX 470 4GB will be much (about 349%) faster with regards to AF than the GeForce 9600 GSO 768MB. (explain)
Pixel RateThe Radeon RX 470 4GB will be much (about 349%) better at full screen anti-aliasing than the GeForce 9600 GSO 768MB, and also able to handle higher screen resolutions without slowing down too much. (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 (in units of MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
