The world-known manufacturer of computer hardware, MSI company, has recently introduced a new graphics card MSI R7970 Lightning with striking design and huge potential. This news couldn’t but rejoice those customers who set rather tough demands towards the performance of their computer hardware. MSI R7970 Lightning can be truly ascribed to the top models line since its deployment and performance records are beyond any doubts.
It should be mentioned that R7970 Lightning delivery set is void of multiple components which could puzzle the customers. Instead, the initial package contains only standard components necessary for installation and utilization. One can find there a detailed user manual, a disk with drivers, adaptor with mini-DisplayPort to be used with full-format socket, DVI to HDMI adaptor, power adaptors, and bridge for adaptors connection into CrossFireX configuration.
Design and Deployment
Dimensions of this graphics card speak for themselves, starting from the length of the device which approximates 35 cm., and relative heaviness which reflect the top class of the device. Each user will have a perfect possibility to feel the whole might of the card once seeing and holding it.
Manufacturers have increased the clock frequency up to 1070 MHz which is considered to be the major peculiarity of R7970 Lightning model. Such development speaks of the substantial performance potential of this graphics card. R7970 Lightning is based on AMD chip Tahiti XT which is worked out on Graphics Core Next architecture.
Circuit Board. Circuit board of R7970 Lightning has been developed with a touch of originality. The board uses Military Class III elements as the basis. Aluminum plate is fixed on the reverse side of the circuit board and functions as protective shield from external damages for the components (while installation, for example). Despite the availability of this plate, it doesn’t deteriorate the process of heat abstraction as far as the power subsystem zone is equipped with a special perforation. Supplementary power supply is connected by means of two eight-contact sockets.
The distinctive feature of the very circuit board is that the general potential of the power supply subsystem has been dramatically increased by the manufacturers, and is fulfilled under 17-phase scheme. Power supply parameters are monitored due to the digital controller which is called to change the quantity of power active phases automatically and doesn’t require the installation of any software. This digital controller is targeted to achieve the improvement of VRM potential.
To continue, MSI company took a decision to integrate a bantam expansion board GPU Reactor. The major task of this board is to decrease the pulse in the power converter circuit which, in its turn, serves to stabilize the operation of graphics card during the overclocking. R7970 Lightning is additionally equipped with 2 chips with firmware which are switched by means of a toggle.
Interface panel is implemented with the involvement of 4 mini-DisplayPort sockets. There are also 2 DVI sockets that work in Single-Link mode. Such mode enables the connection of screens with the resolution up to 1920x1200. Customers, who need to connect the screens of larger resolution, can find such limitation a difficulty, since they will have to employ additional adaptors and DisplayPort.
Cooling System. Graphics card R7970 Lightning has Twin Frozr IV cooling system which is based on a dedicated development Dust Removal Technology. This development implements the process of fan cleansing from dust and external dirtying. The principle of its operation looks the following way: the fans rotate in the reverse side within 30 seconds on the initial system startup; this is done to remove the dust from the fan arms. The cooling system has an auxiliary radiator which cools down the power elements and memory chips.
When in Use
Efficient heat abstraction is achieved due to the large dispersal area of the radiator and a solid fan. Therefore, GPU components are warmed up to 30 degrees when in rest mode. Performance showings will satisfy even the most demanding customers: performance increases up to 10% when in use at the recommended frequency; the performance rate is able to increase up to 24% on additional enforcement. Such showings of R7970 Lightning surpass the performance rate of the preceding models of this manufacturer.
