Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 550 Ti uses a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 RAM runs at a frequency of 1026 MHz on this model. It features 192 SPUs along with 32 Texture Address Units and 24 Rasterization Operator Units.
Compare all of that to the Radeon HD 6450 (OEM) 1GB, which comes with GPU core speed of 750 MHz, and 1024 MB of GDDR5 RAM set to run at 900 MHz through a 64-bit bus. It also is made up of 160 Stream Processors, 8 TAUs, and 4 Raster Operation Units.
(No game benchmarks for this combination yet.)
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 550 Ti should be a lot faster than the Radeon HD 6450 (OEM) 1GB overall. (explain)
Texel RateThe GeForce GTX 550 Ti is quite a bit (more or less 380%) more effective at anisotropic filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 550 Ti is a better choice, by far. (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 MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
