Intel Core i7-1370P vs AMD Ryzen 9 PRO 8945HS vs AMD Ryzen 7 8840HS

Intel Core i7-1370P

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.

AMD Ryzen 9 PRO 8945HS

The Ryzen 9 PRO 8945HS is a powerful Hawk Point family processor (APU) released in April 2024. The R9 PRO 8945HS is identical to the "normal" R9 8945HS in virtually all respects; both come with 8 Zen 4 cores running at 4.0 GHz to 5.2 GHz (16 processing threads), a 16-TOPS Ryzen AI NPU and the top-of-the-line Radeon 780M graphics adapter. Other key features include PCIe 4 and USB 4 support, LPDDR5x-7500 RAM support and 16 MB of L3 cache. Unlike the R9 8945HS however this PRO series chip has ECC memory support and the Secure Processor feature which in a nutshell is an ARM co-processor built into the main chip.

Architecture and Features

Hawk Point APUs are powered by the Zen 4 architecture, just like Dragon Range, Phoenix and Raphael processors are. With this product family, AMD is betting big on generative AI; these chips are said to deliver an up to 40% increase in generative AI performance over 7040 series APUs making apps like DaVinci Resolve and Adobe Photoshop more powerful than ever before.

Unlike Zen 3, Zen 4 features AVX512 support and, thanks to a plethora of other improvements including larger registers/buffers/caches (reportedly at the cost of some of them becoming slightly slower), is supposed to bring an IPC improvement of around 13%.

Elsewhere, the R9 PRO 8945HS has 16 MB of L3 cache and support for super-fast RAM (up to LPDDR5x-7500 or DDR5-5600 with ECC support optionally present depending on the socket). The processor is compatible with USB 4 and thus with Thunderbolt; PCIe support is limited to the 4.0 spec for a throughput of 1.97 GB/s per lane. 20 lanes are available.

OS support is limited to 64-bit editions of Windows 11 and Windows 10 and of course to Linux. Note that the chip isn't overclockable and neither is it user-replaceable as it gets soldered down for good (FP7, FP7r2, FP8 socket interfaces).

Performance

The 8945HS is an R9 7940HS in disguise, so it's realistic to expect the chip to be just slightly faster than the Core i9-12900HK and also the Ryzen 7 7840HS, as far as multi-thread performance is concerned.

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 has 12 CUs (768 shaders) running at up to 2,800 MHz. This is a very fast iGPU, as of late 2023. It will let you use up to 4 monitors with resolutions as high as SUHD 4320p, and it is also capable of HW-encoding and HW-decoding the most widely used video codecs including AVC, HEVC and AV1. More importantly, it is fast enough for proper 1080p gaming as long as one is fine with low to medium detail settings.

Your mileage may vary depending on how high the CPU power limits are, how competent the cooling solution of the system is, how fast the RAM of the system is (there is no dedicated VRAM here).

Power consumption

This Ryzen 9 series chip has a long-term power limit (default TDP) of 35 W to 54 W, giving laptop makers a choice between longer battery life and higher performance. Either way, an active cooling solution is a must for a system powered by this chip.

The 8945HS is built with TSMC's 4 nm process for high, as of late 2023, energy efficiency.

AMD Ryzen 7 8840HS

The Ryzen 7 8840HS is a powerful processor (APU) of the Hawk Point family. This isn't an entirely new laptop chip; instead, it's a rebadged Ryzen 7 7840U, the slightly higher wattage of the 8840HS being the only meaningful difference between the two. The 8840HS has eight Zen 4 cores running at 3.3 GHz to 5.1 GHz that are SMT-enabled for a total of 16 processing threads, while the great Radeon 780M is responsible for 3D processing and similar duties. The 8840HS also features the Ryzen AI technology, now in its 2nd generation.

Architecture & Features

Hawk Point family chips are powered by the Zen 4 architecture, much like Phoenix and Dragon Range family chips are. That's not to say there is no difference between the three. With Hawk Point, AMD is betting big on generative AI; these processors are set to deliver an up to 40% increase in generative AI performance over 7040 series APUs, making apps like DaVinci Resolve and Adobe Photoshop more useful than ever before.

Unlike Zen 3, Zen 4 features AVX512 support and, thanks to a plethora of other improvements including larger caches/registers/buffers, is slated to bring a double-digit IPC improvement over the former.

Elsewhere, the 8840HS has 16 MB of L3 cache and support for super-fast DDR5-5600 and LPDDR5x-7500 RAM. The chip is compatible with USB 4 and therefore with Thunderbolt. It comes with 20 PCIe 4 lanes, giving NVMe SSDs up to 7.8 GB/s of throughput.

Systems built around this Ryzen 7 series APU are designed to run 64-bit Windows 11, 64-bit Windows 10, or Linux. Please note that this processor is not overclockable and neither is it user-replaceable. It gets soldered down for good instead (FP7, FP7r2, FP8 socket interfaces).

Performance

Since this is a 7840U in disguise that we are dealing with here, it is safe to expect the 8840HS to be about as fast as the Core i7-12650H, as far as multi-thread performance is concerned.

Your mileage may vary depending on how high the CPU power limits are, and how competent the cooling solution of your laptop is.

Graphics

The Radeon 780M has 12 CUs (768 shaders) purring away at up to 2,700 MHz. This is exactly the right iGPU for people looking for a bit more horsepower than what Intel's aging Xe options can provide. The Radeon will let you use up to 4 monitors with resolutions as high as SUHD 4320p and it will also HW-decode and HW-encode the most widely used video codecs (including AV1, HEVC and AVC) without breaking a sweat. In terms of gaming, the thing is good enough for 1080p and medium-to-low settings, as of late 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 28 W that laptop makers are free to tune to their liking, with values between 20 W and 30 W greenlighted by AMD. Either way, an active cooling solution is a must for any system powered by this chip.

The 8840HS is built with TSMC's 4 nm process for high, as of late 2023, energy efficiency.
