Nvidia Geforce GTX 650 video card - characteristics review, expert and user reviews

Choosing a computer or a laptop, it is worth paying attention not only to what this device has a processor installed, but also what video card or video accelerator. Particular attention must be paid to it to gamers, architects and those who want the picture on the monitor to be of high quality. Of course, the monitor is responsible for the image quality, but not only it, without a good video card, all its capabilities may not be used.

Currently, the market offers a huge variety of video adapters. Superiority in this sphere is shared between AMD and NVIDIA. Although it is considered that NVIDIA is better.

In the event that you need an excellent budget option, capable of providing high-quality image quality and good hardware capabilities, we recommend you look at the NVIDIA Geforce GTX 650 video adapter. Why to it? First, it has a relatively small cost in comparison with its "older brethren". Although it is inferior to them in power and efficiency, but, nevertheless, it has decent performance.

Detailed description of video accelerator

The basis for this model of video accelerators is a well-known budget videochip called GK107. It works in many mobile devices and in the Geforce GT 640 desktop graphics card. This device provides support for all the features that exist in the top Geforce GT 640 chipset installed in the Geforce GTX 680. It has all the features of the Kepler architecture.

This graphics processor includes one cluster that provides GPC processing. It consists of 2 SMX multiprocessors, which include 384 computing streaming cores, as well as 32 texture modules. 128-bit access provides a subsystem of the graphic chipset of the video card, which is based on two 64-bit memory channels. The law of proportionality and binding to memory controllers stipulates the presence of 16 blocks that perform the raster operations ROP.

Based on this, the possible amount of local video memory NVIDIA Geforce GTX 650 - 1 or 2 GB. The card operates at an effective frequency of 5 thousand MHz. It is lowered by more expensive video accelerator models based on Kepler. The resulting throughput is 80 Gb / s as a result and is quite suitable for budget decisions, since it does not differ from the one that the more expensive and powerful GTX 650 Ti graphics card has.

Like the more expensive devices of this line, the NVIDIA Geforce GTX 650 does not have the technical equipment that supports modern GPU Boost technology. This set of software solutions allows in automatic mode to increase the operating frequencies of the GPU in order to provide maximum performance, while increasing power consumption. It makes it possible to work at maximum frequencies for the device, allowing not to go beyond the installed heat pack. Not bad, right? But, unfortunately, the manufacturer decided that budget cards do not need this technology. Thus, unlike devices more powerful, for example, NVIDIA Geforce GTX 650 Ti, the standard clock speed of the video chip, which is equipped with this device, is fixed - 1058 MHz.

Despite the budget, the video card is an excellent solution for ensuring the stable functioning of even the newest and very demanding video memory programs. Any shooter will not slow down with very fine details of the picture and color saturation of the graphics. It is also capable of providing high quality of the gameplay of multiplayer games, operating on the basis of DirectX 11 and in HD (1080 p) format.

Other features of the video card

The circuit board of this video adapter is short, so you can install only small coolers on it. RSV standard design is simplified, if you compare it with expensive solutions of this line. The length of the board is 145 mm. Additional power is provided by the 6-pin connector, as well as the GTX 660. Image output is possible on three devices. Despite this, the hardware card can support up to 4 displays. To output video information, two dual-link DVI and one HDMI connectors are used.

By using the GK107 GPU in this card, which is used on mobile devices, the video accelerator consumes very little power, even though the device operates at high frequencies. In sleep mode, the device uses only 5 watts, and when playing high-resolution video, only 13 watts. This indicator is the best in this class. More complex tasks require more energy consumption, and the maximum is 64 watts. But even when working at full capacity, the device emits very little heat. Given this, the manufacturer left a 6-pin connector for additional power. It provides excellent opportunities for overclocking the device, increasing its performance, and also provides improved stability of the adapter.

Some partners of the company produce such a device without a connector that provides additional power. In return, they offer overclocked factory solutions. Most of these video adapters, manufactured by partner companies, have overclocking capabilities and a frequency equal to 1100 MHz. If you overclock NVIDIA Geforce GTX 650, the card will give a frequency of up to 1200 MHz. There are models that have enhanced power systems, cooling, providing more efficient operation of devices.

This video card supports all the latest technologies implemented by NVIDIA in their devices. This is PhysX, Adaptive VSync, etc. The new model offers consumers the most current options at the moment - DirectX 11, TXAA, PhysX, adaptive VSync and others.

The NVIDIA Geforce GTX 650 graphics card is an excellent option for upgrading the video systems of gaming enthusiasts with compatible DirectX 10 hardware.

Comparative characteristics of this device from experts

Is this device worse or better than its predecessors? And what is better to take: a video adapter from a competitor - AMD company - or nevertheless NVIDIA Geforce GTX 650? The comparison will answer all these questions.

1. Comparison of the apparatus of the manufacturer. The manufacturer compares the new video card with the Geforce 9500 GT (a little outdated). Thus, it is possible to assess the company's achievements in this area.

When you run games like World of Warcraft: Mists of Pandaria, the novelty shows 4 times better performance than the card with which it is compared. When you start Max Payne 3 the result is the same. The older card is not able to compete with the novelty even when working in the DirectX 9 software package.

The same happens when checking the performance of these devices on MechWarrior Online. The old is not able to compete with the more recent development of NVIDIA. It reproduces only 10 frames per second, when the new one - 40.

2. Comparison with newer devices of the same price category. Let's compare with the accelerator of the previous line, located in the same price category - Geforce GTS 450. This device is based on the GPU and also supports DirectX 11.

With this comparison, the result is also good. The performance of the novelty is 20% higher than the model with which the comparison is made. It has significantly better energy efficiency indicators. This advantage is provided by a new technology, which is absent in the older model, - Kepler. As a result, the performance per unit of energy spent in our device is approximately twice as high.

3. Comparison with modern devices from competitors. The main competitor of NVIDIA Geforce GTX 650, which has modern technologies, is the AMD Radeon HD 7750. But this device, like others, lags behind the budget novelty of NVIDIA. And this despite the fact that the video adapter in question does not have the GPU Boost technology, which makes it possible to automatically increase the operating frequency of the GPU. But even without this technology, the video card from NVIDIA has a frequency of 1200 MHz and higher, while the competitor has only 1058 MHz. As you can see, despite the fact that the price for NVIDIA Geforce GTX 650 is slightly higher, Than its competitor, its capabilities and characteristics more than cover this difference.
