Graphics card NVIDIA GeForce GTX 770, in contrast to the NVIDIA GeForce GTX 780 is based on the already well-known to us the GPU NVIDIA GK104, NVIDIA promises to increase productivity levels by 22% compared with the NVIDIA GeForce GTX 670 and a 65% Compared with the NVIDIA GeForce GTX 570. In theory this is good, but leads us to believe that the NVIDIA GeForce GTX 770 is only enhanced by modifying and overclocked NVIDIA GeForce GTX 680.

MSI GeForce GTX 770 Lightning 031 MSI GeForce GTX 770 Lightning Review, Design and Testing PerformanceNone of the presentations of the new card is complete without a comparison with its competitors, and it is in this role for the NVIDIA GeForce GTX 770 supports AMD Radeon HD 7970 GHz Edition. Based on data from NVIDIA, in games novelty shows, on average, 10-15% higher frame rates, which of course is commendable, but do not forget the excellent overclocking potential solutions from AMD, as well as the cost of new items that cannot be too humane.

MSI GeForce GTX 770 Lightning 04 MSI GeForce GTX 770 Lightning Review, Design and Testing PerformanceAlso note stated excellent scalability of two NVIDIA GeForce GTX 770 Mode 2-Way SLI, which, again according to NVIDIA, is about 80%. And, as we can see, we promise to increase substantially the same in most of today’s popular games, which is good, but in the future we, of course, the self-test operation of a pair of video cards and try to either confirm or refute this statement.

MSI GeForce GTX 770 Lightning 05 MSI GeForce GTX 770 Lightning Review, Design and Testing PerformanceAs is the case with NVIDIA GeForce GTX 780, one of the important features of the NVIDIA GeForce GTX 770 is the presence of the new controller of the fan, which should positively affect the noise level “reference” JI. However, as you remember, as tested NVIDIA GeForce GTX 780, its cooling system also was making all the noise level is quite high at maximum fan speed, as well as all the “reference” cooler turbine.

MSI GeForce GTX 770 Lightning 06 MSI GeForce GTX 770 Lightning Review, Design and Testing PerformanceSince this is all the highlights, which were announced at the presentation, it’s time to go directly to the familiarity with the NVIDIA GeForce GTX 770, but for a start, because in our laboratory test was “non-reference” version of the video card, say a few words about the reference NVIDIA GeForce GTX 770.

MSI GeForce GTX 770 Lightning 07 MSI GeForce GTX 770 Lightning Review, Design and Testing PerformanceAs you can see, the new product is made in the same style as the NVIDIA GeForce GTX TITAN and NVIDIA GeForce GTX 780. Totally agree the cooling system and PCB design, and its dimensions. To display an image using a standard set of video outputs, which consists of a DVI-I, DVI-D, HDMI and DisplayPort. The only information that we currently do not have – this data element base “reference” cards, as well as the device, its power system.
