Nvidia GeForce 300 series

The GeForce 300 series is a series of desktop - graphics chip company Nvidia , which only in the OEM market is available.

description

On November 25th, 2009 Nvidia presented the GeForce 310, the first model of the GeForce 300 series. Contrary to general expectations, it was not a model whose graphics processor was based on the Fermi architecture, which Nvidia had already presented in September 2009, but a new edition of the GeForce 210 based on the GT218 GPU, which in turn has only been for one Month was available in the retail market. As a result, Nvidia came under criticism for the naming, as it did with previous new editions. Nvidia placed the GeForce 310 in the low-budget sector, although the card is initially only intended for the OEM market. On February 9, 2010, Nvidia first listed the GeForce 315, GT 320, GT 330 and GT 340 on the company's website, with all cards based on graphics processors of the previous generation. The official market launch took place on February 22, 2010.

Naming

The GeForce 300 series uses the naming scheme that was first introduced with the GeForce 200 desktop 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 "3" (for GeForce 300). The last two digits serve for further differentiation within the respective service sector.

Letter abbreviation:

• no prefix - low budget
• GT - mainstream

Due to the general drop in prices on the market and currency fluctuations, Nvidia's original classifications do not generally apply.

Notes :

• The specified clock rates are those 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.

Performance data

The following theoretical performance data result for the respective models:

model	Graphics processor / memory
	Computing power of the stream processors in GFlops	Pixel fill rate in GPixel / s	Texel fill rate in GTexel / s	Data transfer rate in GB / s
GeForce 310	067.3	2.4	04.7	08th
GeForce 315	158.4	1.9	07.6	12.6
GeForce GT 320	281.2	8.6	13.0	25.3
GeForce GT 330	385.9	4.4	26.4	25.6
		6.6		24
	420	8th	28.0	32
GeForce GT 340	385.9	8.8	17.6	54.4

Notes :

• The 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. The overall performance of a graphics card depends, among other things, on how well the available resources can be used or fully utilized. There are also other factors that are not listed here that affect performance.
• The 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.
