How much more can you get out of a Radeon RX 5700 using BIOS Flash? Keith May from wccftech.com has investigated this question and has unceremoniously added the BIOS of the RX 5700 XT to the weaker of the two current Navi graphics cards. In the final benchmarks, the flashed reference Radeon RX 5700 was compared to the normal version with and without OC as well as the Radeon RX 5700 XT.
BIOS Flash of the Radeon RX 5700 raises clock limitations, but does not increase the number of shaders
Before jumping prematurely, be aware that a flawless BIOS flash is not guaranteed and risks are associated with such interference. So it can come to a brick, which makes the graphics card permanently unusable. The warranty also expires. Inexperienced users should therefore refrain from a BIOS flash.
The necessary BIOS has been procured first by means of a Radeon RX 5700 XT and GPU-Z. Also in the download archive of techpowerup.com, more precisely in the VGA BIOS Collection, there is a corresponding image. Subsequently, the Wccftech author used ATIFlash (2.93), which is also found on techpowerup.com, to play the Radeon RX 5700 XT's BIOS on its Radeon RX 5700.
After successful Flash, it was first in the Radeon Wattman. The previous limitations were lifted, but there was no increase in the recognized stream processors, so that the Radeon RX 5700 continued to work with 2,304 shader units, which ultimately means a hardware limitation. A full-fledged Radeon RX 5700 XT can not be made from the reference RX 5700 without XT suffix via BIOS-Flash.
The reference clock rates of the Radeon RX 5700 XT are then directly available. That means a base frequency of 1.605 MHz, a game clock of 1.755 MHz and a boost clock to 1.905 MHz. By default, the reference Radeon RX 5700 operates at 1,465 MHz in the base clock, 1,625 MHz game clock and clocks to 1,725 MHz significantly slower. However, the maximum frequency of the RX 5700 XT is not reached in the normal state. Instead, at 1,850 MHz, the first step is closing. Only after raising the power limit by 20 percent was at 1.950 MHz ultimately even more in it.

But it is in the exchange of temperature and power consumption but significantly upwards. Drilling out the power limit, the Radeon RX 5700 flashes up to 390 watts under load, 60 watts more than the reference version of the Radeon RX 5700 XT without adding gimmicks. In the meantime, the temperatures are at the same level, so that hotspot temperatures up to 108 degrees Celsius are reached, while the peak temperature is 87 degrees, which means one more degree each.
In terms of performance, the Radeon RX 5700 can not quite keep up with the RX 5700 XT and increased power limit in the Time Spy benchmark. 8,639 points are here compared to 8,758 points. The Radeon RX 5700 flashed with 8,320 points is more obvious, while the distance to the Radeon RX 5700 with overclock (1,850 MHz and +20% power limit) is only slight (8,192 points).

It looks better in the Firestrike Extreme. Here, the flashed Radeon RX 5700 including the raised power limit with 12,383 points just barely won, while the RX 5700 XT a total of 12,329 points. A narrow lead over the Radeon RX 5700 with overclock is again available for the RX 5700, which has only a RX 5700 XT BIOS.
