AMD Ryzen Z1 Extreme vs AMD Ryzen 7 260

AMD Ryzen Z1 Extreme

The AMD Ryzen Z1 Extreme is a fast high-end laptop processor of the Phoenix series and fastest model of the U-series. It offers 8 cores (octa core) based on the Zen 4 architecture that supports SMT (hyperthreading , 16 threads). The cores clock from 3.3 (base) up to 5.1 GHz (single core boost). The processor includes 8 MB L2 cache and 16 MB L3 cache.

The performance of the R7 7840U is, depending on the workload, only slightly below the Ryzen 7 7840HS (higher base clock speed and TDP). Compared to the previous generation Ryzen 7 PRO 6850U, the 7840U is clearly faster thanks to the Zen 4 architecture and higher clock speeds. Compared to the similar Ryzen 7 7840U, the Z1 Extreme offers no AI engine.

The chip integrates a modern and fasts RDNA 3 graphics card (iGPU) called Radeon 780M with 12 CUs and up to 2.7 GHz clock speed. Furthermore, the Phoenix series include a video engine with AV1 de- and encoding, a new Xilinx FPGA based XDNA AI accelerator (Ryzen AI) that should be faster than the AI engine in the Apple M2 SOC and a dual-channel DDR5-5600 / LPDDR5x-7500 memory controller (with ECC support). The connectivity features includes 2 possible USB 4 (40 Gbps) ports and 20 PCIe 4.0 lanes for a GPU and SSDs.

The Phoenix series uses a single monolithic design (unlike the chiplet design of the 7045HX series) and is manufactured in the modern 4nm process at TSMC. The TDP can be configured between 15 and 30 Watt.

AMD Ryzen 7 260

The Ryzen 7 260 is a fast Hawk Point family chip for laptops that was announced at CES 2025. It features 8 Zen 4 cores (16 threads thanks to SMT support) running at up to 5.1 GHz. The chip is identical to the old Ryzen 7 8845HS and therefore also the Ryzen 7 7840HS (which did have a lower clocked NPU).

Architecture and Features

Hawk Point family chips are powered by the Zen 4 architecture, much like Phoenix and Dragon Range family chips were. The 16 TOPS NPU present here isn't powerful enough for systems built around the 260 to be Copilot+ certified.

Elsewhere, the Ryzen 7 has 16 MB of L3 cache and a seriously fast RAM controller (up to LPDDR5x-7500 and up to DDR5-5600). PCI-Express speeds are capped at 1.97 GB/s per lane which corresponds to the 4.0 spec.

Please note that the APU isn't overclockable and neither is it user-replaceable. It gets soldered to the motherboard for good instead (FP8 socket interfaces).

Performance

Since the R7 260 is an 8845HS / 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.

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 (such as 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 low of very low settings.

Your mileage may vary depending on how high the APU 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 as powerful as possible. Either way, an active cooling solution is a must for a laptop or a mini-PC built around this Ryzen.

The R7 260 is built with a 4 nm TSMC process for high, as of late 2023, energy efficiency.
