Lenovo ThinkPad P14s Gen 6 (Intel) Performance
Under the hood, the P14s G6 is driven by an Intel Core Ultra 7 265H processor, which is part of the Core Series 2 Arrow Lake-H family. This is Intel’s premier mobile-focused and mid-power silicon, offering 16 CPU cores in total along with Intel’s most powerful Arc 140T integrated graphics (Xe-LPG+ architecture) and a fair bit of PCIe lanes for additional expansion.
As a full-fat version of the Arrow Lake-H chip, the 265H gets access to all the hardware offered in Arrow Lake, with the six performance (P) cores topping out at 5.3GHz. Meanwhile, backing P cores for highly threaded workloads is a further eight efficiency (E) cores. And finally, two low-power-efficiency cores (LP-E), which are essentially always-on cores designed to handle light tasks so the other cores can sleep when not in use.
As noted earlier, the system only features a single 32GB SO-DIMM, so the Lenovo system is running with a memory bandwidth performance handicap right out of the gate.
This specific system configuration also features NVIDIA’s RTX PRO 500 Blackwell discrete graphics, which comes with its own 6GB of GDDR7 memory. This is NVIDIA’s entry-level RTX PRO Blackwell part for professional/workstation laptops, and is based on the GB207 GPU. By GPU standards, it is a pretty petite chip, but it has a significant feature advantage over the Intel Arc 140T, and an even bigger performance advantage thanks to its dedicated memory bandwidth and 14 SMs of GPU hardware.
Lenovo pitches the P14s G6 as an AI laptop, and having access to the performance of the RTX PRO 500 and NVIDIA’s CUDA ecosystem certainly contributes to that.
The two GPUs are set up in a hybrid configuration, so even when the RTX PRO 500 is fired up, the integrated GPU on the Core Ultra 7 265H is still driving any connected displays as well as handling desktop duties such as video decoding and framebuffer passing.
Geekbench 6
As we do not review too many laptops around STH, we have a rather limited number of systems to compare the P14S G6 against. Thankfully, a few months ago, we reviewed a SFF PC from Beelink using the same Arrow Lake-H silicon, the Beelink GTi15 Ultra. The Beelink system lacks a discrete GPU, but for a comparison of compute performance, it is not all that dissimilar from the P14s G6, all things considered.
Diving right in, the Lenovo system does start on the back foot in a couple of ways. Besides using a laptop chip inside a laptop (instead of inside a desktop, as is the case for the Beelink GTi15), the Lenovo system also ships with a slightly lower clocked 265H chip, versus Intel’s top-tier 285H.
These clockspeed differences are largely why the Lenovo P14s G6 cannot quite keep up in single-threaded workloads. Meanwhile, in multi-threaded testing, the gap widens due to a combination of clock speed, power/thermal limitations, and the artificial lack of memory bandwidth on the Lenovo system.
Meanwhile, since this laptop also has two GPUs, let us see how the two of them compare.
Under Geekbench 6’s GPU compute test, the RTX PRO 500 Blackwell delivers almost exactly twice the performance of the integrated Arc 140T. Again, the latter is running handicapped due to an artificial lack of memory bandwidth, so this is not an entirely fair comparison. But out of the box, as Lenovo configures the P14s G6, this is how you can expect it to perform. The discrete NVIDIA GPU is more than earning its keep here thanks to its much higher performance.
Geekbench’s AI test also paints a similar picture.
The RTX PRO 500 Blackwell GPU is well in the lead in all cases, and especially with half-precision math, where it has more than a two-fold advantage.
