AMD Ryzen 9 PRO 8945HS vs AMD Ryzen 7 PRO 8840HS
AMD Ryzen 9 PRO 8945HS
► remove from comparison
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 (higher clock speeds) 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 PRO 8840HS
► remove from comparisonThe Ryzen 7 PRO 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 with a slightly higher wattage as well as higher clock speeds on the Ryzen AI NPU. 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. Compared to the consumer 8840HS, the PRO variant supports AMD PRO technologies with management features and usually longer availability and support.
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 R7 PRO 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.
