Over a few months, two nearly identical Gigabyte RX 9070 XT Gaming OC cards passed through my hands. They use GDDR6 chips from different manufacturers. The older card had Hynix; the newer uses Samsung GDDR6, known for lower power draw and temperatures. We’ll examine how this change affects performance, memory temperatures and power, GPU temperatures and clock speeds, and overall card power consumption in our tests.
The tables below show the benchmark results. Please treat them with extra caution: the card with Hynix memory chips was tested six months ago. I used the same press-beta drivers, but 3DMark has been updated since then. Windows has also received many patches, and both the motherboard BIOS and AGESA firmware have been updated. Because of that, some of the differences you see are more likely due to those changes than to the memory itself. Because of that, the biggest differences you see are more likely due to those changes than to the memory itself. Unfortunately, I no longer have the Hynix card, so I can’t retest it.
