Nvidia's PC processor N1X in Geekbench
Initial entries in a benchmark database attest to Nvidia's upcoming N1X 20 CPU cores and more than 4 GHz clock frequency.

Nvidia hasn't even announced its presumed PC processor N1X yet when it already ends up in the database of the Geekbench comparison benchmark. Two runs were made with an HP system.
The single-threaded values are particularly interesting because they give an insight into how fast the individual ARM cores are. The multithreading values can be distorted due to energy restrictions, for example.
In the faster benchmark, the N1X achieved 3096 points in the single-threading test. When using all CPU cores, the processor achieved 18,837 points. Geekbench recognized 20 CPU cores. According to the JSON values, the maximum clock frequency was around 4.05 GHz.

At least in this test, the single-threaded performance is higher than that of Qualcomm's ARM notebook processor Snapdragon X Elite. The fastest version X1E-84-100 achieves just under 2900 points under optimal conditions. Apple's M4 series remains unmatched: The normal M4 achieves almost 3800 points in the single-threading test. The Pro and Max types achieve 3900 thanks to higher clock frequencies.
AMD's top desktop model Ryzen 9 9950X achieves around 3400 points. Intel's Core Ultra 9 285K is just below this.

Same chip base as GB10 possible
The 20 CPU cores read indicate a close relationship to the previously presented GB10, which was developed in collaboration with Mediatek. Mediatek builds the CPU part with ten Cortex-X925 and ten Cortex-A725 ARM cores. The GeForce graphics unit comes from Nvidia. However, Nvidia and partner manufacturers only use the GB10 in mini PCs with Linux and an AI focus. The N1X is also intended for devices with Windows on ARM.
Possible errors in the chip design are currently leading to delays in the GB10 and possibly the N1X. The smaller N1 variant is primarily intended for notebooks. According to the overview, the Geekbench runs were carried out with HP systems and 128 GB RAM.
In the meantime, there has been speculation that Nvidia and Mediatek could slim down the CPU in the N1X. If it remains at 20 cores, the companies could reuse the corresponding chiplet. Meanwhile, the ARMv8 specification in the Geekbench overview is likely to be a readout error. The 900 and 700 ARM cores support the current ARMv9 instruction set.
