This review will examine in detail the relationship between the performance and technical specifications of two popular entry-level graphics accelerators from Nvidia: GTX 750 Ti vs GTX 750. These are the first products of the eminent manufacturer that belong to the Maxwell architecture. Their main feature is low power consumption. But at the same time and with speed they are all right.
Which niche do these graphic solutions belong to?
A comparison of the technical specifications of the GTX 750 Ti vs GTX 750 with other budget solutions indicates that their performance level is relatively equal. But the main feature of these solutions is a high degree of energy efficiency. For the normal operation of such a graphics accelerator, a power supply with a power of only 300 W is sufficient. The power supply of the basic modifications of these graphics accelerators is carried out only through the PCI Express 16X connector, there is no need to connect any additional power connectors to the printed circuit board of the video card. Therefore, the main niche of these graphics accelerators is compact systems with increased requirements for computer energy efficiency and an acceptable level of performance of the graphics subsystem. But at the same time, it is not so rare to find these products in full-size entry-level PCs. These graphic accelerators are targeted specifically at the niche of various kinds of entry-level gaming personal computers.
Video Card Technical Specifications
These semiconductor crystals are manufactured according to the standards of the 28-nm process technology. Focused on the use of 1 or 2 GB of RAM standard "GDRR5". The clock speeds of the processors of these video cards are identical - 1020-1085 MHz. The presence of proprietary GPU Boost technology allows chips to change their frequency depending on the degree of heating and the level of complexity of the task currently being performed. This improves the power consumption of the graphics accelerator. Both of these products are based on an architecture codenamed Maxwell. Its key difference from the previous generation solutions based on the Kepler architecture is the redesigned logic control units and the increased cache memory sizes. All this in total allowed the manufacturer to achieve a significant increase in productivity in combination with a reduction in electric energy consumption.
Performance level of standard modifications
Of course, various synthetic tests show a fairly good level of performance in the scores of these products. But the real level of performance can be seen only in toys. The main indicator in this case is the number of frames per second. It is these indicators for 4 fairly fresh gaming applications are shown in table 1. All these figures are valid for the maximum settings and resolution of 1920x1080. In all toys, the feed "Metro: Last Light", the number of frames per second is sufficient for comfortable gameplay. But in “Metro: Last Light” you will have to lower the parameters of the displayed image to achieve an acceptable value of 30 frames per second or more.
Below is a table that shows the number of frames per second in games for the GTX 750 Ti and GTX 750.
No. p / p | Name of the game | Frames per second for the GTX 750 Ti | Frames per second for the GTX 750 |
one. | Sniper EliteV2 | 59 | 52 |
2. | Metro: Last Light | eighteen | 16 |
3. | "Bioshock Infinity" | 48 | 42 |
four. | Total Var: Rome 2 | 38 | 32 |
Graphics overclocking potential
The most interesting thing is to compare the GTX 750 Ti vs GTX 750 from the standpoint of overclocking potential. One important feature should be noted here: there are modifications of video cards with the prefix “Ti”, which, unlike the basic version, still have an additional power connector. Even in the usual version, overclocking the “750 Ti” to the frequency range 1050-1150 MHz allows you to get an increase of 15-20 percent. Well, if you use the model of the same video adapter, but with improved power supply, you can even get performance in some cases up to 30 percent.
Performance Ratio with GeForce 560Ti
Models below the GTX 560 Ti of the year before last generation of graphics accelerators from Nvidia are generally inappropriate to compare with these new products. They lose both in power consumption and in performance. If we compare the GTX 560 Ti vs GTX 750 Ti with each other, then even in this case the advantage will be on the side of the budget card based on a more advanced architecture. The difference in speed will be about 3-5 percent. Only here energy efficiency in this case will differ significantly.
Comparison with GeForce GTX 660 and GTX 650Ti
A comparison between the GTX 650 Ti vs GTX 750 shows their approximately the same level of performance. But at the same time, energy efficiency is on the side of a fresher product. The difference between them in this regard can reach 30-40 watts. A similar situation is obtained when comparing the GTX 660 vs GTX 750 Ti. The performance level in this case is also comparable, but the energy consumption is several times less for a more recent video card. Therefore, in the eyes of a potential buyer, it is more preferable to look for fresh solutions.
The first representatives of Maxwell architecture against the background of more recent graphics accelerators NVidia
It is difficult to compare the GTX 750 Ti vs GTX 950 with each other. The difference in cost between these solutions is significant and amounts to about $ 50. At the same time, a more recent card is a cropped modification of the GTX 960 (and this is definitely a mid-range device, not a budget one). The difference in performance in this case can reach 40-50 percent. Also, a good overclocking potential of a more recent solution can increase these numbers even more.
Competitors from AMD
An overview of entry-level video cards does not work out completely if you disregard AMD solutions. The direct competitors of the heroes of this review are the "Radeons" of the models R7-260, R7-260X, R7-265 and R9-270. All these graphics cards have almost identical cost and approximately the same level of performance.
It is most interesting to compare the R9 270X vs GTX 750 Ti with each other. The video card from AMD in this case was positioned initially even as a middle-class solution. At the same time, the frequency of the GPU is much lower - only 950 MHz. As noted earlier, at the Nvidia graphics accelerator, the frequency is in the range from 1020 to 1085 MHz and this value varies depending on the degree of heating of the GPU and the level of complexity of the problem being solved at this point in time. The thermal package is much higher for the AMD solution. It also requires an additional power connector. But the most interesting parameter in this case is the capacity of the random access memory bus, which is equal to 256 bits in the R9-270 versus 128 bits in the GTX 750 Ti. Alas, in this case, the solution from Nvidia in terms of performance and speed loses much to its direct competitor. A similar situation with the R7-265. GTX simply does not leave any chances - the 750 Ti are still the same 256 bit RAM bus. Also, the presence of additional power and lower clock speeds indicates that AMD solutions can also be overclocked. Therefore, from the point of view of performance, the products of the last company are preferable. But as part of compact PCs with increased requirements for their energy consumption, it is more reasonable to use Nvidia solutions.
Cost
The basic version of the GTX 750 is estimated by the manufacturer at $ 120. In reality, you can find the most affordable video adapters of this model for $ 135-140. A more advanced modification is estimated by the manufacturer at $ 149. In reality, you can buy such a product for 160-170 dollars. If in the first case such a price is justified and looks very attractive against competitors, then the GTX 750 Ti is not so rosy. By reducing the cost of R9 270 in a competing camp to the same level, it is preferable to purchase the latter. Energy efficiency, of course, will be weaker, but in terms of performance, he will leave far behind any of the heroes of this review. Well, given the lowered clock speed and high overclocking potential of this solution, the choice becomes more than obvious - R9 270.
Reviews
When comparing GeForce GTX 750 vs GTX 750 Ti Users highlight the improved specifications of the latest solution. He has better overclocking potential, and the number of blocks involved in the work is greater, and the speed is higher. In the segment of entry-level compact systems, these video adapters are unrivaled. They simply do not even have an alternative. But in full-sized PCs, the AMD solution based on the R9 270 will be preferable. Although this chip is outdated, its price and speed leave no chance even for the GTX 750 Ti. But this product has long been discontinued and now only its stocks are being sold. After their completion in the segment of entry-level solutions, there will certainly not be a better option than the GTX 750 Ti.
Summary
Comparison between such graphic solutions as the GTX 750 Ti vs GTX 750, indicates further development paths for Nvidia products. This is an increase in performance with a significant reduction in power consumption. It was with a harmonious combination of these two areas that the heroes of this review turned out.
