AMD Ryzen 7 8845HS

The Ryzen 7 8845HS is a powerful Hawk Point family chip that we believe to be a Ryzen 7 7840HS in disguise. The R7 8845HS was brought to life in H2 2023; it features 8 cores (16 threads thanks to SMT support) running at up to 5.1 GHz. Not only does this APU has full might of the Zen 4 architecture at its disposal, it also boasts the 2nd generation Ryzen AI technology. Last but not the least, the Radeon 780M serves as the integrated GPU.

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 that there is no difference between the three. With Hawk Point, AMD uncorks its 2nd generation Ryzen AI technology meaning the new processors are expected to deliver an up to 40% increase in generative AI performance over 7040 series APUs. Dozens of popular apps such as DaVinci Resolve support this technology, as of late 2023.

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

Elsewhere, the 8845HS 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 to the motherboard for good instead (FP7, FP7r2, FP8 socket interfaces).

Performance

Since the 8845HS is a 7840HS in disguise, it's safe to expect it to be just slightly faster than the Core i9-13900H and also the Ryzen 9 7940HS, as far as multi-thread performance is concerned. This is a very fast chip, as of Q3 2023.

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 R7 8845HS is buit with TSMC's 4 nm process for high, as of late 2023, energy efficiency.
