It comes with a slightly different model number; last week it was the SM-G900S, while this time it's the SM-G900F.
Those could well be two different versions of the same phone on separate carriers, so don't discount this rumor on account of a single letter's variation.
Interestingly, though, the Galaxy S5, which should be Samsung's most epic flagship yet if and when it launches next year, lost to the iPhone 5S and the Galaxy Note 3 in Rightware's Browsermark test.
Second place is first loser
The Browsermark test flexes various aspects of a device's web-browsing capabilities and assigns it a score and ranking based on its prowess.
The Samsung SM-G900F, which may or may not be a version of the Galaxy S5, scored a 3303.88, lower than the Note 3's 3353.07 and the 5S's 3669.91.
But another version of the Note 3 with a slightly different model number came in just below the Samsung device, and Sony's Xperia Z1 was under that.
But Rightware, the administrators of the Browsermark benchmark, noted that the Samsung device in question was running a slightly outdated version of the Chrome browser at the time the test was conducted, and that may have affected the results.
Galaxy S5 specs
When a similarly-numbered Samsung device appeared in a different benchmark test last week it had some interesting specs.
Those included a a 2560 x 1440 display, a 2.5GHz quad-core Snapdragon 800 processor, an Adreno 330 GPU, and Android 4.4 KitKat.
There was also speculation that given the resolution the phone could have a 5.25-inch screen with pixel density at 560ppi, as rumors last month said of the Galaxy S5.
If it's not the Galaxy S5 we're looking at in these tests, it could actually be any number of handsets - Samsung has a total of four or five new phones planned for early 2014 already.
