Compare any two graphics cards:
Geforce GTX 760 vs Radeon HD 4670 1GB
IntroThe Geforce GTX 760 comes with clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 1152 SPUs along with 96 TAUs and 32 ROPs.
Compare all that to the Radeon HD 4670 1GB, which features core speeds of 750 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR4/GDDR3/DDR3/DDR2 RAM. It features 320(64x5) SPUs as well as 32 Texture Address Units and 8 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 760 should in theory be a lot faster than the Radeon HD 4670 1GB overall. (explain)
Texel RateThe Geforce GTX 760 is a lot (more or less 292%) faster with regards to anisotropic filtering than the Radeon HD 4670 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Geforce GTX 760 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 maximum amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
