Some RX 9070 XTs are reportedly barely slower than others due to Samsung GDDR6 reminiscence chips
Bilibili {hardware} channel 51972 has launched a video detailing benchmarking comparisons of twenty-two completely different fashions of the AMD Radeon RX 9070 XT with a barely troubling conclusion—the variants making use of Samsung GDDR6 reminiscence chips look like barely slower when in comparison with their SK Hynix-equipped cousins.
How a lot slower? By, err, 2.6% on common. Granted, it isn’t precisely a large distinction, however it’s nonetheless somewhat disappointing to know the newest Samsung-using RX 9070 XT revisions are technically the slowest, even when its by a tiny margin.
in response to 51972, amd cn confirms that samsung g6 used on 9070xt has looser timings leading to barely worse efficiency.海力士=hynix三星=samsungbilibili 51972, 9070xt roundup checkhttps://t.co/DQC5SOm3Qb pic.twitter.com/7Sn0dJEmvNJune 12, 2025
AMD seems to have began utilizing Samsung GDDR6 reminiscence for the RX 9070 XT pretty lately—and it has been reported that the brand new chips present higher thermal efficiency, though we have but to check one for ourselves.
In accordance with 51972, AMD has confirmed to the channel that Samsung’s GDDR6 reminiscence chips have barely looser timings in comparison with their SK Hynix equivalents, and that accounts for the marginally decrease figures within the benchmarks.
Now, earlier than all of us go sharpening our pitchforks, it is price stating {that a} 2.6% discount in efficiency is a fairly small drop off. The outcomes had been additionally recorded in a single benchmark, 3DMark Pace Method, and such a small distinction is unlikely to make a lot of a distinction in real-world gaming assessments.
When our Dave examined an SK Hynix-equipped RX 9070 XT he was impressed by its RTX 5070 Ti-like efficiency total, and will that 2.6% drop translate to our benchmark outcomes, it nonetheless would not place the AMD card a lot additional behind its considerably costlier competitors.
It is unclear as as to whether producers will clearly differentiate between playing cards utilizing Samsung chips or the SK Hynix variants, however it appears unlikely at this level. What’s additionally unclear is whether or not the Samsung-equipped playing cards will take to overclocking in the identical means the unique spec did.
We discovered our Asus evaluation pattern gained a big quantity of efficiency with a -120 mV undervolt and the reminiscence pushed to 2600 MHz, which might doubtless counteract the two.6% drop if the brand new reminiscence chips are able to the identical. We cannot be capable to say for particular till we check one for ourselves, although, and as with all overclocking figures, your mileage could range.
Nonetheless, slower is slower. A 2.6% distinction would not be sufficient to maintain me up at night time if I purchased a brand new RX 9070 XT, but when these outcomes show to be correct, it seems to be a downgrade for the Samsung-using playing cards nonetheless.
