Don’t do that with your new AMD graphics card or it’ll run slower

The new AMD graphics card reaches a disadvantage: for others they are more often than in accordance with the demands of others. They made it to the overclocking of your 7900. And they found an unexpected surprise.

It turns out that AMD graphics cards have been less convulsive, and if for some they are more than conformable to what they are called, for others they’re underperformance. They decided to close your RX 7900 and found an unexpected surprise. I don’t have power. Why is that happening?

The latest release of the RX 7900 had one of the most absurd controversies, in any way, its clock speed due to the fact that people talk about clock speed above threeGHz. We should say that the Radeon dealer didn’t talk about those speeds, but the efficiency of the electricity supply. In any case, these rumors have caused many users to overclock their next-gen AMD graphics cards.

Why does overclocking the RX 7900 lower performance?

The increase in clock speed should be a good addition to performance. However, on the RX 7900, overclocking can sometimes get out of control. Let’s not forget that the GPU is a complex chip, composed of different parts with different speeds and power ranges. Thus it is common for designs to assign different electrical domains. Think of rooms in a house with different switches that can be turned on and off.

Despite the difficulty of having light switches that are simple to set, they can’t take off the computer and consume the paper. As of now, they found that when done overclock an RX 7900 and the chip exceeds certain speed limits, the memory controller clock speeds get smaller. In the small chip around the principal, remembering that in the first CPU with chiplets.

What’s the consequences? It is easy for graphics cards to depend on bandwidth for their performance; as the clock speed rises, its demand rises, but in turn, the transfer rate between the GPU and the low memory costs eventually creates a screw that can’t be achieved without losing its processing capacity. In the picture below, you see how, for example, The increase in clock speed to 3281 MHz means a slew of memory time to 1461 MHz. That said, 2,5GHz upgrade from 20Gbps to 12Gbps speed. And the bandwidth is almost half the amount that a user takes to a compass, from 960 to 576 GB/s.

What causes of all this?

No matter how we talk, we know that due to the high power 12+4 pin connector controversy, many have linked to NVIDIA, and many of the problems related to the new standard PCI-SIG which AMD is going to use when the right time comes, and the related problems. The Radeon industry started its RX 7900 with traditional power connectors.

The AMD’s most powerful GPU is able to go for higher clock speed, but already within the constraints of having a new connector. What makes us wonder if 2023 would make sure that this is a feasible RX 7950 XT ready with a greater volume but also with much better performance. For a better version, AMD wouldn’t do that with the same chip, but with a paired version, or, instead, with a optimized solution. I don’t believe this is better since I was using the NVIDIA RTX 4090. What says the RX 7900’s overclocking is worse. Without change, that’ll ring faster.
