Hardly anyone noticed that lately humanity greatly concerned with the preservation of the environment in an acceptable form of life, or simply the environment (often mistakenly referred to as the environment). At the level of the most narrow-minded noticeable progress in the automotive industry. This is more stringent emission standards forcing manufacturers to find a number of technically complex and often problematic for the consumer solutions from soot filters on diesel engine and finishing with a gradual transition to electric motors. Certainly, the changes occur in other areas, including IT. In contrast to the above mentioned car industry is all possible steps down to two factors - the reduction or elimination of highly hazardous substances in components and reduce their energy consumption. The first factor is usually governed by the directives of production and consumption, so the vast majority of users care about, but the second is important. It is fair to note that the original attention to power consumption of computer components from both the producers and the users are not born out of concern for the environment or the economy. The fact is that the vast majority of electricity consumed electronics translates into heat, which is necessary to avoid overheating dissipate. Thus, the increase in energy consumption Components inevitably entails increasing size and noise of the cooling systems, which seriously reduces their quality of consumer. It also is the primary cause of concern for the retention of power within acceptable limits. Recently, however, due to the fact that the performance of the PC for a long time and repeatedly surpassed the level needed for a comfortable run most household and office tasks, fashion has become a small, quiet and economical system.
In the field of graphics cards such market trends led to the development of integrated graphics processors built into the chipset first and then himself CPU. However, among the discrete solutions, we continually witness the appearance of a modification of standard models with reduced
power usually is indicated by the word "Green" ("Green"), which became synonymous with the semantic of "green." But miracles do not happen, and in most cases the appearance of the word, if it really means lower power versions, so that it runs slower than the standard model. And it is not always a bad thing. In certain cases, the "green" solutions by reducing the power, heat and noise, the performance level is close to a "hot, voracious and noisy" standard, may be the most suitable option. For example, when creating a notorious HTPC with an eye on not too resource intensive 3D-games.
In this review, we consider it a "green" card - GeForce GTX 460 SE Green Company InnoVISION Multimedia Limited (brand - Inno3D).
Technical characteristics
GeForce GTX 460 appeared a long time ago - in the summer of 2010, so their performance should be very familiar. First of all, remember that the original boosters have two versions - one equipped with a 768 MB, the other - 1024 MB standard memory GDDR5. Version with 1024 MB GDDR5 uses four 64-bit controllers, that is, a 256-bit bus, and has 32 blocks raster operations. In the modified GTX 460 768MB GDDR5 one controller is not involved, therefore, the tire has a bit 192 bit, which means that the card has only 24 ROPs. At the same time, both versions have 336 unified shader processors (in the nomenclature of NVIDIA - cores CUDA), 56 texture units, GPU in both operating at 675 MHz (1350 to the shader), and the video memory at 900 (3600) MHz.
Over time, however, appear to have accumulated quite a lot NVIDIA partially defective crystals, which have traditionally been put into circulation. Thus, the market appeared graphics card, the GPU is turned off one cluster SM, contains 48 CUDA cores and eight texture units. As a result, the GeForce GTX 460 SE with the suffix has only 288 of stream processors and 48 texture units.
Here, obviously, to prevent drastic difference in performance with the GeForce GTX 460 768 MB, modification GeForce GTX 460 SE 1024 MB has a 256-bit memory interface and 32 ROPs. At the same time, the frequency of the GPU and memory in a model with an index number of SE reduced.
As is known, the maximum power consumption of the GeForce GTX 460 768 MB is slightly lower than the GeForce GTX 460 1024 MB. Accelerator GeForce GTX 460 SE on this parameter corresponds to the conditional version with 768 MB. In turn, the GeForce GTX 460 SE Green InnoVISION of repeats of the reference GeForce GTX 460 SE.
Thus, guided by the original data, there is no objective reason to believe that the Inno3D GeForce GTX 460 SE Green can consume less power than ordinary GTX 460 768 MB. Perhaps we will find something for further inspection?
Design and cooling system
PCB design video card Inno3D GeForce GTX 460 SE Green is almost completely identical to the standard version of the GeForce GTX 460 SE. The only difference is the location of six-pin connector for the power supply and the fact that in this case there is only one slot, while on the reference GTX 460 SE are two.
The decision, to be honest, strange, because in itself elimination second connector does not reduce energy consumption, and this parameter of the card is 150 watts - the numbers, frankly, a rather big, so the second slot would not hurt. By the way, the pads and the corresponding track for the second connector on the board are present, and this is due to the fact that on the basis of the printed circuit board Inno3D produces a number of accelerators, including the overclocked versions of GeForce GTX 460 1024 MB.
Eight gigabit memory chip card total capacity of 1024 MB is connected to four 64-bit memory controller located on the GPU. In this case, the chips used Hynix H5GQ1H24AFR T0C rated at 1000 (4000) MHz. Given that the composition of the product Inno3D GeForce GTX 460 SE Green clocking their staff of 850 (3400) MHz, the "enlightened" people are guaranteed to speed up the memory at 150 MHz, not going beyond the denomination chips.
Pulse down converter voltage GPU is built on a three-phase circuit and is controlled by the PWM controller uP6204BJ production uPI Semiconductor Corp. The chip is able to work with a wide range of input voltages, which may be necessary when using low power and very high quality power supplies. However, the same can be attributed to almost any modern Buck Controller.
Simple synchronous voltage regulator chip memory controller running uP6161S14.
Both converters are used ordinary MOSFETs that, given the word "Green" in the title card looks a little strange. All the same keys with low-resistance source-drain channel (RDS (ON)), and hence the efficiency of this would have been much relevance.
Inductors also fall within the type, with all the disadvantages. In particular, at high load inductors produces a characteristic high-frequency whistle. In terms of the capacitors used on the map again, it's simple. Common polymer used aluminum containers that do not differ low series resistance.
Thus, the word "Green" in the name of the video card Inno3D GeForce GTX 460 SE Green may be considered advertising message and nothing more.
Panel video outputs Inno3D GeForce GTX 460 SE also alludes to the orientation of the budget, for one of the two outputs DVI-I has been replaced with D-Sub, used only old monitors, CRT, LCD, or the cheapest. And this at a time when DVI-I elementary transformed to D-Sub adapter with passive due to the presence of additional contacts in the connector carrying analog RGB-signal.
However, the vast majority of users is enough for one connector Dual Link DVI-I, and to connect the LCD and Plasma TV panels most suitable connector is present here HDMI.
Cooling system
Cooling system GPU card Inno3D GeForce GTX 460 SE Green differs from one version NVIDIA.
Radiator is made by pulling silumin workpiece through a die followed by cutting. This is the most inexpensive, but quite effective type of construction for centuries used to cool chips with relatively low heat.
Blown radiator fan with an impeller diameter 72 mm. Blades ingenuous forms have a fairly steep angle of attack, providing a high level of performance. A side effect of this design of the impeller is that much of the air is forced not parallel (to the fins), and perpendicular to the axis of rotation, but in this case it turned into an advantage. Top cover protection system, directing "parasitic" threads of memory chips and power elements of power converter, providing them with some air cooling.
Rotational speed fan depends on the temperature of the GPU and regulated circuit on the PCB card by PWM.
Operation and acceleration
The noise of the cooling system video card Inno3D GeForce GTX 460 SE Green, running at idle or low 2D-load by reducing the frequency can be called acceptable. Outdoor bench working fan is clearly audible, but in a closed system unit and separate it from the general background of the running system is unlikely to succeed. GPU die temperature while hovering around 40 ° C. With increasing load and heating the GPU fan speed and grow, and with them the noise. However, even with the most severe operating conditions, the GPU temperature and fan speed to quickly stabilize at 78 ° C and 2500 rev / s. The fan's noise is noticeable, but not beyond a comfortable level.
Certainly, the accelerator GeForce GTX 460 SE is hardly seen as a card purchased with a view to further overclocking - after missing the core CUDA and texture units no acceleration can not be returned. However, overclocking ability Inno3D GeForce GTX 460 SE Green still of some interest. As it turned out, the card has a remarkable overclocking potential. Opportunities for overclocking the memory through the use of GDDR5 chips with high nominal frequency was quite high. The maximum frequency of 4080 MHz GDDR5 was, well above the nominal value of 3400 MHz. Conquering the GPU at 726 MHz at which its maximum temperature has increased by only 2 ° C.
Such acceleration allowed Inno3D GeForce GTX 460 SE Green to estimate 13,276 GPU Score in 3D Mark Vantage package with presets Perfomance. This is much higher than 12,528 points, which demonstrates the NVIDIA GeForce GTX 460 1024 MB (hereinafter described on the test bench).
