Amd radeon rx 480 loses pci certification

The AMD Radeon RX 480 was released as a revolution in the world of GPUs by offering very high performance for a recommended price of $ 199 in its version with 4 GB of memory. However, not everything has been pink since its Polaris 10 silicon has shown a higher power consumption than expected causing some headaches for AMD.

AMD Radeon RX 480 benchmark is penalized for its high consumption

After the premiere of the AMD Radeon RX 480, it was learned that the card has excessive power consumption through the PCI Express slot on the motherboard, drawing more electrical power than recommended. The reference Radeon RX 480 has a single 6-pin connector that is capable of offering up to 75W of power, in addition to the 75W that the PCI-Express slot can provide, so we have a total of 150W, a figure that matches the TDP of the card.

The problem comes in that the card shows maximum consumption peaks of 164W, this situation causes the card to force the PCI-Express slot pulling up to 86W and this can create problems of reboots in the computer and in more serious cases damage to the same board base. The situation is exacerbated if we overclock since the card consumes up to 180W, so the force of the PCI Express slot on the motherboard is even greater.

This problem has caused the Radeon RX 480 to lose the PCI-SIG certificate so the company will not be able to put it on the card or in all the associated marketing material. Luckily for AMD the issue only affects the reference model and custom cards with a single 6-pin power connector. For the peace of mind of our readers, most personalized cards include an 8-pin connector, so in that case they do have the certificate that ensures that there is no problem.

For the benefit of AMD it must be said that the problem has been solved with its Crimson controllers but it seems that it has not been enough to avoid punishment.
