"Overall, Huawei says the Kirin 980 will be 40 percent more CPU efficient, 105 percent more GPU efficient, and roughly 20 percent faster than the Kirin 970."
"The dedicated neural processing unit (NPU) is now a dual-core processor for 134 percent higher performance and 88 percent higher AI efficiency than the NPU in the Kirin 970."
These are radically different numbers from last month's Kirin 980 launch. They're still here in your article from back then.
"Huawei already claims that the Kirin 980...outperforms the Kirin 970 by 75%.
The Kirin 980 also features the new Mali G76MP10 GPU, which, as Huawei claims, beats the preceding Mali G72 chip by 46% in terms of performance and 176% in terms of power efficiency. The 980 also has a new, larger NPU. Huawei projects that it will improve on that of the Kirin 970 by up to 134%. while using 88% less power. "
Only the NPU claim remains the same, but "88% less power" was a bad way to put it, it sounds more like the new NPU only uses 12% the power of the previous one.
