GeForce GTX 745 graphics adapter: an ideal price-performance ratio

A good combination of price and technical parameters allows using the GeForce GTX 745 video accelerator in entry-level gaming systems. Some modern toys on it will go with average settings, and some - on the minimum. Also, some obsolete software solutions in this case can be launched with the maximum quality. It is this accelerator that will be considered below.

Solution positioning

The video card GeForce GTX 745, first of all, is aimed at the segment of low-cost entry-level gaming computers. In this case its parameters are sufficient and allow to solve any problems, but for an average computer this will not be enough. In addition, it should be noted that in free sale it is almost impossible to find. It can only be supplied in large quantities for OEM compilers. Therefore, it can only be purchased as part of an electronic computer.

Graphic chip. Memory subsystem

The GeForce GTX 745 video card is based on the GM107 graphics processor, which, in turn, is based on the Maxwell architecture. This chip is manufactured according to the standards of 28 nm process technology, and on its silicon substrate is 1870 million transistor elements. The size of the substrate in this case is 148 mm ² . There are 384 graphics processors on it, the clock frequency of which in the nominal mode is 1033 MHz.

Rasterization modules - 16, and texturing units - 24. The memory controller is aimed at working in conjunction with GDDR3 chips with a frequency of 1800 MHz. In some cases, manufacturers indicate the presence of GDDR5 chips, but even if they are installed, the actual frequency will be reduced to the maximum possible 1800 MHz. That is, there will not be any gain from using faster memory. Possible amounts of video buffer can be 2 GB or 4 GB. The total bit width of the RAM bus is 128 bits, which are divided into 2 parts 64 bits at the physical level. Ultimately, this allows you to get throughput at 28.8 Gb / s.

Energy efficiency. Switching. Reviews and Prices

The strength of Maxwell's architecture, which underlies the GeForce GTX 745, is energy efficiency. Its thermal package is limited to 55 watts, and this allows it to supply power to the adapter without additional cords. Also the cooling system, although active, takes only one slot, that is, it is compact enough. This board is designed for installation in the slot of the PCI E motherboard in the 16X version. The output ports of the graphic information are three: VGA, DVI and, of course, HDMI. In the supported state, such an adapter can be purchased for 60-75 dollars, and in a new state it can not be purchased. Energy efficiency and low cost are the strengths of the GeForce GTX 745. Reviews highlight such disadvantages in it: mediocre performance and the inability to purchase on a free sale.

Results

GeForce GTX 745 is a well-balanced graphics solution. It is the most suitable for entry-level gaming systems. This equipment will go to most of the toys, but not at high settings. But taking into account the price, this is natural.
