If you don't follow almost daily the video card market it is really complicated to understand the differences between the several different nVidia graphics chips available on the market today. To facilitate knowing and understanding the difference among these chips, we have compiled the following table:

* The manufacturer can setup a different memory clock rate or interface, so pay attention because not all video cards based on this chip have this spec. The memory transfer rate will depend on the interface and clock rate used. See how to calculate below.
** GeForce 7950 GX2, GeForce 9800 GX2 and GeForce GTX 295 use two graphics processors in parallel (SLI mode). The specs published are for just one of the chips.
*** GeForce 8, 9, 100 and 200 series use two clocks, the higher one is used by the shader unit and the lower one by the rest of the chip. The shader unit is unified, meaning that these chips don't have separated pixel shader and vertex shader units. Read our article GeForce 8 Series Architecture for more information.
^ Based on PCI Express 2.0, which doubles the available I/O bandwidth from 2.5 GB/s to 5 GB/s if a PCI Express 2.0 motherboard is used.
(TC) means TurboCache. TurboCache is a technology that allows the video card to simulate more video memory by using part of the main system RAM as video memory. Read our tutorial on this subject for a better understanding on this feature.
At first nVidia’s profusion of letters may seem confusing. The GeForce FX 5700 Ultra chip works at a higher clock than the GeForce FX 5900, GeForce FX 5900 Ultra and GeForce FX 5900 XT chips, and this may make you think that a GeForce FX 5700 Ultra is the faster than chips in the 5900 series.
But that is not really so. Chips from the GeForce FX 5900 series access the memory at 256 bits per time, while the memory is accessed at 128 bits in the FX 5700 series. That makes the 5900 series memory access performance twice as fast as those of the previous series. For instance, the GeForce FX 5700 Ultra would have to access its memory at 1,700 MHz – the double of the memory clock used – to reach the memory performance of the GeForce FX 5900 Ultra.
Another example. From the table you may think GeForce 6600 GT is faster than a GeForce 6800 because it has a higher clock rate (500 MHz against 325 MHz). But GeForce 6800 accesses memory 256 bits at a time while GeForce 6600 GT accesses memory 128 bits at a time, and also GeForce 6800 processes 12 pixels per clock tick, while GeForce 6600 GT processes eight pixels per clock.
The right way to compare the memory performance of different chips is through their memory transfer rate, which is calculated using the formula (clock x bits per clock ) / 8.
Another difference is the graphic processor of the FX 5900 series, which processes eight pixels per clock pulse, while the graphic chip only processes four pixels per clock in the other series. In other words, despite having a higher clock, the graphic processing performance of the GeForce FX 5700 Ultra is inferior than those of chips from the FX 5900 series, as they process the double of pixels when work at the same clock (simply put, the GeForce FX 5700 Ultra would have to work at twice its clock to have the same performance of the GeForce FX 5900 Ultra).
Therefore, it is not correct to compare graphic chips only through their clocks.
We must be careful with the GeForce FX 5900 XT, too. While ATI uses the letters "XT" to indicate high-end chips (for ex.: Radeon 9800 XT), nVidia uses the same letters to indicate the low-end chips of the series (see table).
You have to be very carefull with low-end video cards using nVidia chips, because they can use different clock rates and different memory interface from the table. For example, you can find GeForce FX 5200, GeForce FX 5500 and GeForce 6600 with 64-bit or 128-bit interface. We've seen GeForce FX 5200, GeForce FX 5500 and GeForce 6200 with 32-bit interface on the market!
As for the DirectX version, check the table below:
DirectX | Shader Model |
7.0 | No |
8.1 | 1.4 |
9.0 | 2.0 |
9.0c | 3.0 |
10 | 4.0 |
10.1 | 4.1 |

On the table below we compare the temperature and power specs for nVidia chips. Chips not listed mean that nVidia does not publish their maximum temperature, maximum power and minimum PSU power specs.
It is important to notice that these are all “worst-case scenario” values. Under normal operation the graphics chip will present a temperature below its maximum and consume a power below what is published on the table. The same goes for the minimum required power supply, where nVidia publishes a “safe” value, taken in consideration that the power supplies are labeled with their maximum peak power, not with their maximum continuous power.
