AMD recently introduced the RX 590 graphics card, using the 12nm process to improve the Polais core, performance and price is not bad, but the RX 590 power consumption after the frequency increase has also increased, this problem has become AMD's unspeakable hidden, simply not in the official specifications The power consumption data of the RX 590 is mentioned.

For the RX 590, we already know that its architecture is no change compared to the RX 580. It is still 2304 stream processor units, 144 texture units, 32 groups of ROP units, with 256bit GDDR5 memory, but the core frequency of the RX 590 has been increased. 1469-1545MHz, non-public version of the RX 590 graphics card may be higher, so the game performance is 10% higher than the RX 580 graphics card, and most of the game performance is ahead of the non-public version of the GTX 1060 graphics card.

Although there is no special surprise, but considering the RX 590 graphics card to raise the frequency but did not increase the price, this graphics card is still qualified as an upgraded version. However, the cost of the RX 590 after raising the frequency is not low, and the power consumption is correspondingly increased compared with the RX 580. This has also become the most dissatisfied player for the RX 590.

AMD itself is of course the clearest about the increase in power consumption. In order to solve this problem, AMD is official.websiteThe power consumption of the RX 590 graphics card is not directly given. The TDP and graphics power supply requirements are directly saved.

Comparing the official specifications of the RX 590 and RX 580 graphics cards, it can be seen that AMD saves the typical power consumption of the graphics card and the PSU power supply requirements. The RX 580 is available, but the RX 590 does not mention it.

In our initial evaluation, we mentioned the typical power consumption of the RX 590. The 225W is 40W higher than the 185 RX 580 graphics card. The power consumption is basically proportional to the performance improvement.

Players' dissatisfaction with the RX 590 power consumption is actually due to the high expectations of the 12nm process. AMD officials have not confirmed whether the 12nm process is TSMC or GF, only that the new process brings better efficiency and performance, but No matter which 12nm process is used, it is optimized on the 16/14nm process, and the change is not big. If it is GF's 12nm process, according to the performance of AMD's previous 2nd generation, it does increase the maximum operating frequency, and the operating voltage is reduced, but the reduced voltage is not obvious on GPUs that require high performance. The increase is sufficient to offset the power reduction caused by process improvements.
