VideoCardz has shared some early memory overclocking tests for NVIDIA’s newest flagship card, the GeForce RTX 3080. NVIDIA is advertising this GPU with 19 Gbps GDDR6X memory, but it appears that the cards should have little trouble hitting 20 Gbps or higher speeds. While the Founders Edition is reportedly the only SKU out there currently without strict power limitations (i.e., it can hit 370 W), overclocking seems lenient even with conservative AIC models, such as the one tested here (320 W).
“The GPU was only overclocked by 70 MHz and memory by 850 MHz,” VideoCardz explained. “This was the highest clock speed for this particular sample (for GPU and memory overclock). The sample had a maximum TDP of 320W (so NVIDIA reference, even lower than the sample screenshotted [below]). The results are not spectacular but at least we know that RTX 3080 can finish the tests with such memory overclock.”
You can check out the complete metrics below. The Time Spy Extreme test alludes to a decent performance bump (86 FPS vs. 102 FPS) when the memory is overclocked, with temperatures hanging around 70 degrees Celsius.
