The Ryzen 7 7840HS is a powerful Phoenix family chip that saw the light of day in H1 2023. The processor features 8 cores (16 threads thanks to SMT support) running at 3.8 GHz. The highest Boost clock speed achievable is 5.1 GHz.
Not only does this APU has full might of the Zen 4 architecture at its disposal, it also comes with the new Ryzen AI technology that's set to make generative AI more ubiquitous than ever before. Last but not the least, the Radeon 780M serves as the integrated GPU.
Architecture & Features
Phoenix family chips are powered by the Zen 4 architecture, much like Dragon Range family chips are. The latter however lacks hardware AI workload acceleration capabilities that Phoenix has. Ryzen AI is coming after Intel's DL Boost and GNA technologies; time will tell if this move by AMD is a good idea.
Perhaps more importantly, Zen 4 introduces AVX512 support (which Zen 3 chips did not have) and, thanks to a plethora of other improvements including larger caches/registers/buffers across the board, is set to bring a double-digit IPC improvement.
Elsewhere, the 7840HS has 16 MB of L3 cache and a seriously fast RAM controller (up to LPDDR5x-7500 and up to DDR5-5600, ECC-enabled memory included). PCI-Express speeds are capped at 1.97 GB/s per lane which corresponds to the 4.0 spec.
This Ryzen 7 series chip is designed to run 64-bit Windows 11, 64-bit Windows 10 or Linux; please note that it isn't overclockable and neither is it user-replaceable. It gets soldered down for good instead (FP7, FP7r2, FP8 socket interfaces).
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.
Graphics
The Radeon 780M (12 CUs / 768 shaders, up to 2,700 MHz) is capable of powering 4 monitors simultaneously with resolutions as high as SUHD 4320p. It will also have little issue hardware-encoding and hardware-decoding the most widely used video codecs (AV1, HEVC, AVC). As far as gaming is concerned, the thing will let you play most games at 1080p as long as you are fine with moderate quality settings. Long story short, this is the best iGPU money can buy, as of H2 2023.
Your mileage may vary depending on how high the CPU power limits are, how competent the cooling solution of your system is, how fast the RAM of your system is (there is no dedicated VRAM here).
Power consumption
This Ryzen 7 series chip has a long-term power limit (default TDP) of 35 W to 54 W, giving system makers a choice between improving battery life and making the system they're designing insanely fast. Either way, an active cooling solution is a must for a laptop or a mini-PC built around this APU.
The 7840HS is built with TSMC's 4 nm process for high, as of late 2023, energy efficiency.
The Intel Core i7-1370P is the flagship Alder Lake-P CPU, which is to say, an expensive 28 W part meant for use in ultra-light (yet actively cooled) laptops. This CPU will probably be announced in early 2023 and it has 6 performance cores (P-cores, Golden Cove architecture) mated to 8 efficient cores (E-cores, Gracemont architecture) according to a leak on Geekbench. The P-cores are Hyper-Threading-enabled for whopping 20 threads when combined with the E-cores. The clock speeds can reach up to 5.2 GHz for the performance cluster (1.9 GHz base speed) and 1.4 GHz to 3.9 GHz for the efficiency cluster. The CPU is quite similar to the older Core i7-1280P but probably offers higher clock speeds.
Full vPro feature set is supported by this Core i7 ("Enterprise" tier, allowing for remote device management).
Architecture
The i7 is a continuation of Intel's efforts to use the ARM-developed big.LITTLE technology for its own benefit. A single "little" Alder Lake core is supposed to be just as fast as a Skylake core (as found in the venerable Core i7-6700HQ among other options) which is six years old at this point. All of a Core i7-1280P's CPU cores enjoy access to 24 MB of L3 cache. The integrated memory controller supports up to 64 GB of LPDDR5-5200, DDR5-4800, LPDDR4x-4267 or DDR4-3200 RAM. Just like the other 12th Gen Intel Core processors, Core i7-1280P comes with Thread Director which is a new functionality designed to help Windows 11 decide which cores to use for what workload for best performance and efficiency possible. Hardware acceleration of AI algorithms is supported via GNA 3.0 and DL Boost (via AVX2). PCI-Express 5.0 support has not found its way into Alder Lake P processors, so users will have to be content with PCI-Express 4.0 for the time being. The CPU still only supports PCIe 4.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.
Please note this is not a user-replaceable CPU. It gets soldered permanently on to the motherboard (BGA1744 socket interface).
Performance
Multi-thread performance is most comparable to AMD Ryzen 9 5900HS, Ryzen 9 PRO 6950HS, Intel Core i9-11980HK. Which is impressive but comes with a catch; long-term performance sustainability will be rather poor unless the Power Limits are very high and the cooling solution is a truly capable one.
Graphics
The built-in graphics adapter in the form of the 96 EU Iris Xe running at up to 1.5 GHz has seen no change from what was built into the 11th Gen Tiger Lake-UP3 processors, like a i7-1165G7, which is hardly a downside as this iGPU is loaded with modern features such as AV1 video decoding capability and SUHD 4320p monitor support.
Power Consumption
The i7's base power consumption (also known as the default TDP value or PL1) is 28 W, with 64 W being its maximum Intel-recommended Turbo power consumption (also known as the PL2). The "Minimum Assured" power consumption is fairly high at 20 watts. All in all, an active cooling solution is nearly a must.
Core i7-1370P is built with Intel's third-gen 10 nm process marketed as Intel 7.
The Intel Core i5-1350P is a mid-range Raptor Lake-P (Alder Lake-P refresh) family CPU, a 28 W part meant for use in ultra-light, ultra-thin (yet actively cooled) laptops. This CPU was announced in early 2023 and it has 4 of the 6 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores are Hyper-Threading-enabled and clock between 1.9 GHz (base) to 4.7 GHz (single core boost) for a total of 16 threads when combined with the E-cores. The E-cores clock from 1.4 to 3.5 GHz and offer a similar performance as the old Skylake cores.
The performance should be similar to the old Core i7-1260P and therefore well suited for even demanding tasks.
The CPU now supports PCIe 4.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.
The i5-1350P is rated at 28 Watt TDP (PL1, 64 Watt PL2 for short bursts). The CPU is manufactured in the further improved Intel 7 process (10nm SuperFin).
