Compare any two graphics cards:
GeForce GT 440 1.5GB vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce GT 440 1.5GB uses a 40 nm design. nVidia has clocked the core speed at 594 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this model. It features 144 SPUs as well as 24 TAUs and 24 Rasterization Operator Units.
Compare those specs to the Radeon HD 6570 (OEM) 1GB, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this model. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GT 440 1.5GB should in theory be quite a bit superior to the Radeon HD 6570 (OEM) 1GB in general. (explain)
Texel RateThe Radeon HD 6570 (OEM) 1GB will be a little bit (approximately 9%) better at anisotropic filtering than the GeForce GT 440 1.5GB. (explain)
Pixel RateThe GeForce GT 440 1.5GB is quite a bit (approximately 174%) faster with regards to anti-aliasing than the Radeon HD 6570 (OEM) 1GB, and able to handle higher resolutions without losing too much performance. (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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
