AMD Fiji XT R9 390X Leaked For The Third Time On Zauba - 20nm Looks Promising

AMD's elusive high-end GPU has been spotted for the 3rd time in the Zauba aircraft database. The flagship will allegedly power the R9 390X.

This fourth dimension all the same different the previous two leaks non 1, not ii and non even three just four PCB assemblies for the GPU have been shipped. And for the first time the listing included a very peculiar suffix "(FOC)" which we believe stands for Full Operational Capacity. This signals that the carte du jour has exited the early on prototyping stage as finalized samples are being shipped for finish-stage testing and evaluation. The R9 390X moniker will but serve as a identify holder for this article until we know for sure what AMD has decided to call it. Nevertheless there'south potent indication that this is going to exist the new flagship GPU from AMD to pb the charge on the 2022 graphics refresh.

AMD Fiji XT R9 390X Leaked For The Tertiary Fourth dimension On Zauba

If yous call back back in November we had reported that there are iv dissimilar Fiji XT image cooling units. With the leaked Hydra hybrid cooling unit being merely one of them. The four Fiji XT units recently shipped could be i of each. Likely for the purposes of testing and making the final decision on which one is going to be used for the mass produced graphics cards. Information technology may as well just stop up being pure coincidence.

This is indeed the third fourth dimension that Fiji XT has made its manner to the shipping database. And the 2d time it did so in disguise. The first time the GPU was leaked it had been frankly listed equally Fiji XT but as we had discussed in our last commodity covering the second appearance of the GPU. Someone at AMD had actually realized this and proceeded to omit the Fiji XT classification/code name from future listings. This occasion is no exception and as with the previous listing the lawmaking name has been omitted. Still just similar final time enough of the clarification (effectively all of it except "Fiji XT") has been left out unchanged. So we tin confidently conclude that this is indeed Fiji XT.

If the previous SiSoftware Sandra leak is anything to become by and then we're looking at a 4096 GCN core GPU with 4GB of stacked High Bandwidth Memory and a 4096bit wide I/O memory interface. All built on a cutting edge manufacturing process. I've discussed in cracking detail the numerous indications that AMD had given equally to which process Fiji XT may be manufactured on. Equally things currently stand 20nm is shaping upward to exist the process of choice for a number of upcoming products from AMD.

TSMC's 20 SoC has been described as being inappropriate for discrete graphics cards by some due to its low power nature. However TSMC's 20nm SoC procedure has proven to be easily capable of hitting excellently high clock speeds. The procedure manages to sustain frequencies just as loftier as 28nm if not slightly higher, making it an ideal candidate for detached GPUs.

Nosotros know this thanks to Nvidia's just appear 20nm Tegra X1 SOC which features the Maxwell GPU architecture. Based on Nvidia'south official figures the integrated Maxwell GPU operates at a frequency of 1Ghz. That's 50mhz above the integrated GPU of the Tegra K1 and simply ~200 mhz beneath the desktop GM204 based GTX 980 and GTX 970 graphics cards. 200mhz is the same frequency delta that stands between the 28nm Tegra K1 and the 28nm discrete Kepler GPUs. The Tegra SOCs (and notebook GPUs) are often clocked more conservatively than their desktop siblings for power saving purposes rather than due to a fault of the manufacturing process. So we're looking at a 20nm process from TSMC that not only performs likewise as the loftier performance versions of 28nm just also consumes significantly less power.
