Review Gigabyte GeForce GTX 960 G1 Gaming

Being in thought over how to initiate a review of the next video, I decided to look at things from the other side. It is necessary to assess progress in reducing one table all graphics processors released in the last couple of years.

One manufacturer makes desperate attempts to modify the successful architecture GCN, but somehow all the enthusiasm dissipated after the release of a single core. The second company, on the contrary, is constantly evolving small but very practical steps, moving in the right direction. That is why the proportion occupied by AMD in the market drops while at Nvidia increases.

Although, frankly, a lot of progress not seen for a long time. The only thing won the California-based company – in reducing the power consumption of their graphic solutions. As a result, no longer need to keep two large family of GPU, because Maxwell allows the chip to market discrete graphics cards and notebooks.

We move on to the next creation Nvidia – GM206-300, presented at this time graphics card Gigabyte GeForce GTX 960 G1 Gaming (GV-N960G1 Gaming-2GD).

And – the length of the PCB without cooling system and strips the video out port.
B – the width of the printed board contacts without PCI-E and the cooling system.
C – the height of the horizontal plane of the circuit board to the level of the upper surface of the cooling system.
D – diameter of the fan / s on the outer radius.

A1 – the length of the PCB, based cooling system (if beyond the printed circuit board) to the output port strips.
B1 – the width of the printed circuit board contacts without PCI-E, but with the measurement of the cooling system (if beyond the PCB).
C1 – height, considering the back plate (if any) heatsink or screws to the upper surface level of the cooling system. If it is below the height of the back strap video out port, then measure the height to the top of the bar.

Graphic Card Gigabyte, unlike other similar models, equipped with one, it is not superfluous port DVI. The total number of video output increased to six. At the same time, you can use five, but with a twist.

Yes, you can connect multiple displays and ordinary GeForce GTX 960 using three DisplayPort and one DVI. In general, multi-monitor configurations makes sense, when you create a group of several high-resolution displays (2560 x 1440 more). In this case, there is no HDMI port, and on the Gigabyte GTX 960 remains useful video outputs exactly the same as on the versions with the reference set of ports.

Perhaps this could be circumvented by using two full-port DVI, but in this version you will not be a pair of DisplayPort. So in the case of an extended review of the hero of ports is a compromise.

PCB

No new and original ideas, good GM206 is quite a saving GPU. Is that for high frequencies it works engineers resorted to installing as many as six power phases.

In reality, the power supply system consists of three phases, which are separated in parallel through doublers. They are located on the back side.

Magic coils are designed to completely overcome the disease outside peep at the partial load on the graphics processor. Based on further testing, developers Gigabyte managed to find a solution to this issue. G1 Gaming – the first graphics card, do not publish squeak under load.

The memory is traditionally placed at the end of the printed circuit board. The rest – no power LED, and ways to circumvent the protection of others.

Especially sad, because to work using two 6pin connector. This ensures that the total power required to accelerate to any level. It remains to verify that the engineers have done with the BIOS, and how they have complied with all the requirements for Nvidia restrictions.

PWM controller for all GeForce GTX 960 one – it NCP81174. He also works with a couple of other accelerators Maxwell: GeForce GTX 970 and GTX 980.

Four memory chips made by Samsung are wired to the front and rear. They are designed for speeds up to 1750 MHz (effective frequency 7000 MHz), a bus width is 128 bits.

The graphics core Maxwell released in late 2014. Nominal frequency 1241 MHz graphics make for GPU (GPU Boost up to 1304 MHz) and 1750 MHz memory. In reality, the declared figures frequencies are almost never the same.

Little about ASIC Quality

By popular demand cite alleged “quality” assessment program GPU GPU-Z.

In the future, you will realize that ASIC Quality evaluates the parameter is not responsible for the dependence of the ratio of the acceleration and the applied voltage to the GPU. True quality is measured after final assembly video core when the crystal put on textolite substrate and through contacts current is passed. The general principle of assessing the same, but each developer uses their own unique ways and unwilling to share them with your competitors. After all, the sooner you check the weight of the processors, the lower production costs.

The question arises how much GPU rejected during the final test? A little bit, because the bulk of the marriage is already deselected during the production of the crystal and can only ask for it marked the rated voltage. Table for GeForce GTX 960 single and can be viewed in the VGA BIOS. Theoretically, the worse the processor, the greater should be the rated current, but this is not always the case. Inside the GPU many different feed units: some are quite simple and operate over a wide voltage range, while others, complex and operate only under certain conditions.

For example, TMU and FP64 Cuda kernel large, they account for a fair area. Accordingly, they must be “right” to feed? No, again an error, one of the most demanding power to the unit – a task manager! If the entire GPU operates stably at 1.0 V, but the controller fails and 1.1 V, the rated voltage of the table is increased by one step. Suppose at 1.125 in GPU becomes hassle-free, and GPU-Z compares VID 1.125 with a common base and gives ASIC Quality of only 60%. In reality, such a GPU can be overclocked even better than someone ASIC above. After the failed plot to TMU unit.

Therefore, performance ASIC be taken skeptically. In fact, in assessing the quality of the graphics processor, there are many other nuances. But, alas, share them with the audience does not allow a signed NDA.

Conclusion

Personally, I have a video card left with the impression beta. Sure, it laid great potential – more than the base frequency 1450 MHz, the highest rated TDP level with a large margin under acceleration, normal cooling power circuits, a good design of the main radiator, no squeak chokes. But tell me what to do to hang on two samples provided by a fan?

And yet, on the one hand – this is a reason to rejoice, because you buy a video card that works on your head faster than the competition. On the other – there is no doubt that the copy shop will work at such high frequencies, since the official specifications may vary widely with the test results.
