SoC on N4P.

The CPU consists of 1x Cortex-X4 prime core clocked at up to 3.2GHz, 3x Cortex-A720 cores at 3.0GHz, 2x Cortex-A720 cores at 2.8GHz, and 2x Cortex-A720 cores at 2.0GHz. The new chip is 31% faster than last year’s Snapdragon 8s Gen 3 while drawing 39% less power.

New Adreno 825 GPU, which Qualcomm is advertising to offer a 49% improvement on the graphics side compared to the Snapdragon 8s Gen 3.

Snapdragon X75 5G modem, Wi-Fi 7 and Bluetooth 6.0 connectivity.

This surely sounds like a perfect chip in so many ways. Roughly Apple A15 in Single Thread which is good enough. If this was on N3P it would have rivalled A18 in Single Thread.

And I expect this to be cheaper than the Elite. This should push the average Android performance up.

Now waiting for Mediatek to respond.

Qualcomm Snapdragon 8 Elite Single Thread Efficiency (Oryon Mobile)- Bilbili

There seems to a reviewer on bilbili (S White Database) who reviewed Single Thread power consumption/efficiency for the Qualcomm Oryon core using Geekbench 6.

The Oryon core scores 3261 while consuming 7.6W of power.

Dimensity scores 2901 while consuming 7.9W of power.

A18 pro scores 3568 while consuming 6.6W of power.

Looking at the graph, it seems that at an iso power of 7.6W, Oryon has a ~15% performance advantage over the Cortex X925.

At iso performance, Oryon matches Dimensity’s score while using ~2.5-3 less watts of power.

Compared to the A18 pro, Apple seems to retain a sizable P/W lead. 540.6 points/W (A18 Pro) compared to 429.07 points/W (Oryon). Translates to a 25% P/W advantage.

Looking at iso power however, the gap closes, Apple retains a 15% lead over the Oryon core.

Unable to compare iso performance since A18 pro has a single data point, but considering the lead over Dimensity is similar, it is likely Apple is similarly 30-40% more efficient at iso performance.

Impressive showing by Qualcomm.

Apple and Qualcomm only includes L1 as L2 are shared.

Mediatek includes L2.
