Nvidia GeForce 100 series
GeForce GeForce 100 series is a series of desktop - graphics chip company Nvidia , which only in the OEM is available -Markt.
GeForce series arose from the marketing need to classify the existing graphics chips of the GeForce 9 series in the new naming scheme of the GeForce 200 series, which was published shortly before . Despite its name, the GeForce 100 series can therefore be classified chronologically after the GeForce 200 series, but technically identical to the GeForce 9 series.
Technical
GeForce chips of the GeForce 100 series are identical to the respective chips of the GeForce 9 series and therefore all support the Shader model 4.0 (SM 4.0) according to DirectX 10, OpenGL 3.3 , CUDA and thus also PhysX .

Naming
The GeForce 100 series uses a naming scheme similar to that used since the GeForce 200 series . All graphics chips are identified with a letter abbreviation to classify the performance sector and a three-digit number that generally begins with a “1” (for GeForce 100). The last two digits serve for further differentiation within the respective service sector. Since the GeForce 200 series, which appeared earlier, already covered the high-end market, the abbreviation GTX was not used in the 100 series.
- Letter abbreviations
- G - Low-Budget
- GT - mainstream
- GTS - performance
- GTX - high-end
Confusion is caused by the fact that Nvidia already had and has the GeForce 100 cards on the market as GeForce 9 cards (as of January 2009), which in turn already existed technically identically in the GeForce 8 series. Corresponding renaming was carried out, first to the naming scheme of the 9 series and now to the scheme of the 100 series (e.g. 9500 GT → GT 120). This means that one and the same cards are sometimes on the market under three different names.

- Hints
- GeForce specified clock rates are the recommended or specified by Nvidia. However, the final specification of the clock rates is in the hands of the respective graphics card manufacturer. It is therefore quite possible that there are or will be graphics card models that have different clock rates.
- The date indicated is the date of the public presentation, not the date of availability of the models.
- "MGCP" stands for "Maximum Graphics Card Power" and describes the maximum power consumption of a graphics card that is officially specified by nVidia and can be expected under normal operation. Under certain conditions, however, an even higher power consumption can be achieved. Therefore, the Maximum Graphics Card Power cannot be equated with the TDP .
- GeForce clock frequency of the memory is also often given as twice as high. The reason for this is the double data rate (DDR).
Performance data
The following theoretical performance data result for the respective models:
model | Computing power of all stream processors ( GFlops ) |
Fill rate of the graphics processor |
Data transfer rate to graphics memory ( GB / s) |
|
---|---|---|---|---|
Pixel (GPixel / s) | Texel ( GTexel / s) | |||
GeForce G100 | 33.6 | 2.3 | 4.5 | 8.0 |
GeForce GT 120 | 134 | 4.0 | 8.0 | 16.0 |
GeForce GT 130 | 180 | 6.0 | 12.0 | 38.4 |
GeForce GTS 150 | 705 | 11.8 | 47.2 | 64.0 |
- Hints
- GeForce specified performance values for the computing power via the stream processors, the pixel fill rate, the texel fill rate and the memory bandwidth are theoretical maximum values. GeForce overall performance of a graphics card depends, among other things, on how well the available resources can be used or utilized. There are also other factors that are not listed here that affect performance.
- GeForce specified computing power via the stream processors refers to the use of both MUL operations, which is not achieved with graphics shader calculations, since further calculations have to be carried out. In these calculations, the computing power of the stream processors is therefore lower.
