AMD Radeon R9 Fury X Photo Album Published – GPU-Z Screenshot Shows 128 ROPs Instead of 64

It’s not yet the time for Fury X performance reviews but we have a beautiful photo album of the new card and a peculiar GPU-Z screenshot. Notably AMD has already seeded R9 Fury X cards to the press and reviews are coming on the 24th. One such member of the press decided to run GPU-Z and lo and behold, it’s reporting 128 ROPs instead of 64. But before we get into this interesting finding let’s briefly revisit Fury X’s specs.

AMD R9 Fury X , R9 290XThe Radeon R9 Fury X features the “full fat” version of AMD’s FIji GPU. Code named Fiji XT this chip is 596mm² large making it the biggest GPU AMD has created by far. In this vast silicon area over four thousand GCN stream processors reside as well as 256 texture mapping units and a massive 4096bit memory interface. Essentially giving each GCN stream processor its own lane by which it can access HBM. This next generation High Bandwidth Memory is vertically stacked on an interposer and provides a whopping half a terabyte per second of bandwidth.

Diligent readers will point out that we in fact reported, exclusively, that Fury X would launch with all of the previously mentioned specifications a week before AMD’s event at E3. Incidentally we also reported that Fiji XT features 128 Render Output Units, instead of the 64 figure disclosed by AMD. This is because GPU-Z had reported, and still reports, that Fiji XT does indeed feature 128 ROPs.

We don’t know exactly why GPU-Z is reporting this number of ROPs. It’s just a false data entry in most likelihood that should be corrected with a future update. Since the memory bandwidth, texture fill-rate and the pixel fill-rate are also reported incorrectly. Regardless of what’s being reported by GPU-Z it’s worth noting that not all Render Output Units are created equal.
Both of AMD’s Tahiti and Pitcairn GPUs share the same number of ROPs. However the ROPs in AMD’s Pitcairn GPU are notably smaller and less capable than the ones inside Tahiti. It’s not implausible that AMD could have engineered each of Fiji’s ROPs in such a way to provide more throughput than a Hawaii ( R9 290X ) ROP. I’m certainly not implying that this is the case as we don’t really know for certain yet. We may be able to find out on June 24 after the various reviews go online.


AMD did not reveal any substantial details about Fiji’s architecture and how it compares to Tonga. Which powers the R9 285 and is AMD’s latest and only GCN 1.2 GPU. We have reached out to AMD to find out why no architectural details were revealed at the E3 event. We’ve been told that it was simply too difficult to parley this type of information over a power point presentation due to time constraints. As it happens none of Fiji’s architectural details are actually embargoed. So we’ll hopefully bring you some of those juicy bits soon.
