To rub it in into Nvidia, AMD announced that these new cards do not require one to rebuilt their PCs. Nor there is any need for any new power adapter.

It’s because these cards will not be using the new 16-pin power adapter, which Nvidia is using in its RTX 4090 cards. To those who are unaware, the internet is filled with reports of these new 16-pin power adapters melting and potentially even damaging the RTX 4090 cards.

Instead, RX 7900 XTX will require 2 8-pin PCIe GPU power cables, which is a standard now. Custom graphics card manufacturers might add one more 8-pin requirement though, to allow for more overclocking.

In addition to above, AMD detailed how their new graphics cards come with DisplayPort 2.1 and the latest generation of graphics cards from their rival (Nvidia) come with just DisplayPort 1.4 support. AMD says that a lot of display manufacturers, including Dell, Samsung, ASUS, LG and Acer are going to launch displays with DisplayPort 2.1 support starting next year.

AMD also announced new FSR 2.2 which is an improvement over FSR 2.

AMD claims that with RX 7900 XTX, one will be able to game at 1440P at high refresh rates. With the likes of Apex Legends reaching 300 FPS, Overwatch 2 reaching 600 FPS and Valorant reaching 833 FPS.

In 4K gaming, these new cards do even better. AMD claims that at max settings with FSR up-scaling enabled, many AAA games reach 350 FPS. With some multiplayer games even reaching 700 FPS.

AMD also showcased a game running at 96 FPS at 8K resolution with FSR enabled.

It also claimed that in Ray-Tracing at 4K, many games are able to run above 60 FPS with FSR enabled.

AMD then announced its partnership with many game developers, including Ubisoft and Epic and claimed optimized performance for the Radeon graphics cards in their gaming engines and upcoming games.

FSR 3 Announced

AMD in its announcement also announced a new version of it’s up-scaling tech FSR. Namely, FSR 3. It seems to be directly rivaling Nvidia’s DLSS 3. Those unaware, DLSS 3 is accused of inserting fake frames into the games to make it look smooth but in real the outcome is not so smooth performance increase.

FSR 3, AMD claims, uses new fluid motion technology. Coming in 2023, AMD claims it will provide 2x more FPS over FSR 2.

Software, Streaming and Solutions

AMD dedicated the third part of it’s conference to three different things. Software, Streaming and Solutions.

They detailed the AMD Adrenalin Software for AMD graphics cards which offers state-of-the-art features and next level gaming experiences, streaming and creation. To put the point forward, AMD showed how AMD Adrenalin Software offers so many features in one unified UI, without any registration or log-ins required and it does not track the users either. This is a direct targeting of Nvidia GeForce Experience, which does have these problems.

In new features, AMD announced a new Hypr-RX mode in the AMD Adrenalin Software. Hypr-RX combines all the performance boosting technologies of the Adrenalin all at the same time to boost the gaming performance in a one-click experience to improve the frame rate and latency.

It showed how a game, with Hypr-RX, saw the FPS increase from 90 FPS to 166 FPS and latency decrease from 30 ms to 11 ms. The new Hypr-RX tech is going to come out early next year.


AMD claims it has worked with a famous video streaming software to improve video streaming quality across all bit-rates on Radeon RX 6000 and RX 7000 series. It also detailed how AV1 support is going to improve streaming a lot.

There are many important points we would like to make. Besides all the marketing taglines, AMD seems to have done quite a good work. Especially when it comes to pricing and power usage. This card is most likely going to rival Nvidia GeForce RTX 4080 graphics cards, not RTX 4090.

Some Twitter users like @harukaze5719 even made a graph showing how it might perform compared to Nvidia GeForce RTX 4090 and results look promising.

Another famous Twitter user @Kepler_L2 is disappointed by its Ray-Tracing performance though. Honestly, many of us don’t care about the Ray-Tracing performance as long as the main performance is good enough.

The chiplet design is quite an interesting move by AMD. We will have to see how much improvement or a problem it can be. Simply put, chiplets are easy to manufacture when compared to massive single processors. However, they have various problems associated with them, like performance issues between chiplets and latency between them. However, going forward we might see all processor manufacturers, whether it’s CPU or GPU, to adapt this technology.

Meanwhile, TechPowerUp is reporting that ASUS has already announced its own RX 7900 series cards with 3 8-ping power plugs.

Coming back to performance. It’s never wise to believe what the company says. They might say anything they want. A lot of the performance stats mentioned in the conference are with the FSR enabled, which does not show true performance numbers.

It’s only when the reviews and benchmark arrive that we might understand how things stand, whether AMD can take on Nvidia properly. Till then, we will remain quite excited about it.
