Sapphire NITRO Radeon RX 5700 XT is one of the fastest graphics cards on the Navi 10 chip
Sapphire officially introduced the NITRO + Radeon RX 5700 XT graphics card, which is one of the fastest Radeon RX 5700 XTs, as well as one of the most anticipated versions of this video card. In addition, the leadership of the novelty is confirmed by the test results published by a number of thematic resources.
The NITRO + Radeon RX 5700 XT video card is equipped with a large cooling system, which includes two aluminum radiators through which five nickel-plated copper heat pipes assembled in a copper base pass. Separate radiators are installed on the memory chips. Three fans are responsible for blowing the entire structure, two of which have a diameter of 95 mm, and the third, located in the center, is 87 mm. A reinforcing plate is fixed on the back of the board.
The novelty is built on a printed circuit board of its own design Sapphire and has an enhanced power subsystem, which consists of 11 phases (8 + 1 + 2) and two 8-pin auxiliary power connectors. The manufacturer claims a power consumption of 265 watts. Also note that the NITRO + Radeon RX 5700 XT has two BIOS chips. The set of video outputs includes two HDMI 2.0 and DisplayPort 1.4 connectors.
Of course, Sapphire could not leave the NITRO + Radeon RX 5700 XT without factory overclocking, and it is very impressive here. The base frequency is increased from the standard 1605 to 1770 MHz, the average frequency in games is announced at 1905 MHz, and the maximum Boost frequency reaches 2010 MHz. The memory frequency of GDDR6 remained the reference. 1750 MHz.
Factory overclocking allowed Sapphire to circumvent the reference Radeon RX 5700 XT by an average of 3-4%, with a maximum margin of up to 10%. But catching up with the GeForce RTX 2070 Super did not work: the new NITRO + Radeon RX 5700 XT lags by an average of 6-10%, depending on the resolution.
Manual overclocking allows you to achieve a GPU frequency of 2150 MHz, however, under load, the average frequency is 2050–2070 MHz. GDDR6 video memory manages to overclock to 1900 MHz. Overclocking allows you to increase the performance of the video card by 2-3%, adding several FPS in games. However, this increases energy consumption by up to 18%.
But the cooling system remains rather quiet and does its job well. The GPU temperature under normal operating conditions is 72 ° C, while in acceleration it increases by only 1 degree. The noise level is only 33 dBA.
