AMD has dismissed stories that its new Radeon RX 7900 XT and XTX graphics boards are affected by a bug that impacts efficiency. AMD mentioned that the brand new graphics chips’ shader pre-fetch {hardware} is absolutely useful as meant, regardless of rumours that had advised in any other case.

Stories of bugs related to RDNA 3’s shader pre-fetch {hardware} emerged when a firmware flag which appeared to modify off shader pre-fetch performance was uncovered.

AMD has clarified that the performance in query was a particular experimental function versus the general shader pre-fetch {hardware} in an announcement to Tom’s {Hardware}.

“The code in query controls an experimental operate which was not focused for inclusion in these merchandise and won’t be enabled on this technology of product. This can be a frequent business observe to incorporate experimental options to allow exploration and tuning for deployment in a future product technology,” AMD informed Tom’s {Hardware}.

It’s, after all, completely routine if not truly common for any massive, advanced chip to have some {hardware} flaws. Likewise, it is common for some performance to be fused off. Precisely what qualifies as a critical bug and what’s merely a function that’s being examined with a view to full implementation in future {hardware} is open to interpretation and mischaracterisation, each by chip makers and business observers.

Whether or not this explicit function was really meant to be absolutely useful this time round or was, as described, merely experimental is one thing solely AMD is aware of. So, what truly issues is how the brand new chips carry out total. Does RDNA 3 ship a fantastic gaming expertise?

For positive, there’s a case to be made for AMD’s new GPUs not fairly hitting their targets. Clock speeds of the 7900 XT and XTX are arguably disappointing for an structure AMD says was constructed for 3GHz and past. Most significantly, the brand new GPUs’ efficiency is considerably inconsistent — very spectacular in some video games, much less so others.

That is one of many causes we have been left barely underwhelmed by RDNA 3, scoring the XTX at 81% as a substitute of the 90%-plus you’d anticipate of a really nice new graphics card. However it’s not even practically a catastrophe. Actually the 7900 XT and XTX are very fast graphics playing cards. They’re simply not fairly the game changers we would been hoping for based mostly on pre-release advertising and marketing data from AMD. 

Does that make RDNA 3 notably buggy? Most likely not. However, equally, RDNA 3 most likely is not fairly the GPU structure AMD was initially hoping for given it could actually’t but compete right on the very excessive finish with Nvidia’s RTX 4090 boards. “But”, nevertheless, is the operative phrase. Time will inform simply how aggressive RDNA 3 will show.
