Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 can be processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.

2 Responses to “Geforce GTX 670 vs Radeon HD 7850”I have recently bought GTX 670...due to HD 7850 wasn't enough powerfull to max out my brand new Crysis 3 game!
I was Between GTX 670 and HD 7970 but considering that GTX 670 is using much lower power consumption and have more overclock stabillity than HD 7970 was the reason that i bought GTX 670!!!
Both cards are great if you play sport/rpg/simulator/strategy games then go for AMD if you play games like Battlefield 3 or Crysis 3 or Batman Arkham city then nVidia all the way!
Moreover nVidia drivers are much better than ATi's is!
So I bought the HD 7850 and I overclocked it to 1050 mhz Core Clock and 1450 mhz Memory Clock WITHOUT any changes to power! This GPU is simply a beast if you OC it. Its even better than an R9 270X now. I deffinately recommend you to buy it. It is really cheap and it can run Fallout 4 on max setting easily!
