AMD Ryzen 3 5300U vs AMD Ryzen 7 H 260 vs AMD Ryzen 5 8645HS
AMD Ryzen 3 5300U
► remove from comparison
The AMD Ryzen 3 5300U (not to be confused with the A4-5300, a CPU released in 2012) is a Lucienne family processor designed for use in thin and light laptops. The R3 5300U integrates four cores (quad core) based on the Zen 2 microarchitecture. They are clocked at 2.6 (guaranteed base clock) to 3.8 GHz (Turbo) and support SMT for a total of 8 threads. The chip is manufactured on the modern 7 nm TSMC process. Compared to the older and similar Ryzen 3 4300U (Renoir), the Ryzen 3 5300U offers SMT and slightly higher clock speeds. The faster Ryzen 3 5400U is based on the newer Zen 3 architecture. See our hub page on the Renoir Processors for more information on the Lucienne / Renoir architecture.
In addition to the four CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics adapter with 6 CUs at up to 1500 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 4 MB level 3 cache can be found on the chip.
Performance
The average 5300U in our database matches the Core i5-11300H, the Core i7-11375H and also the Ryzen 5 4500U in multi-thread performance, making it an outstandingly good chip as far as sub-US$700 laptops go.
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.
Power consumption
The Ryzen 3 series chip has a default TDP of 15 W, a value that laptop makers are allowed to change to anything between 10 W and 25 W with clock speeds and performance changing accordingly as a result. By going for the lowest value possible, it will be possible to build a passively cooled system around the chip, however, most companies will do the opposite to achieve higher performance levels.
The AMD Ryzen 3 5300U is built with TSMC's 7 nm manufacturing process for average, as of mid 2023, energy efficiency.
AMD Ryzen 7 H 260
► remove from comparison
The AMD Ryzen 7 H 260 is a high-end notebook processor from the Hawk Point series with 8 cores and hyperthreading (SMT), which means it can process up to 16 threads simultaneously. At release, the CPU is only available in China and is technically practically identical to the older AMD Ryzen 7 8845HS or Ryzen 7 7840HS (slower AI engine).
The performance of the second-fastest model in the Hawk Point series should only be slightly behind the Ryzen 9 7940HS (+100 - 200 MHz clock, e.g. only 2% slower Turbo). As a result, the performance at 54W TDP should also be comparable to the AMD Ryzen 7 7745HX (also 8 Zen 4 cores, max 5.1 GHz, 55W, 32 MB L3) and thus clearly ahead of the old top model AMD Ryzen 9 6980HX resp. 6980HS (with lower TDP).
The chip integrates a modern RDNA 3-based graphics card (iGPU) called Radeon 780M with 12 CUs and up to 2.7GHz including AV1 video engine. Furthermore, a Xilinx FPGA-based XDNA AI accelerator is also integrated, which is now clocked higher. Hawk Point offers 2x USB 4 (40 Gbps), 20 PCIe 4.0 lanes and a dual-channel DDR5-5600 / LPDDR5x-7500 memory controller (with ECC support).
The Hawk Point series is a single chip (unlike the Dragon Range 7045HX series) and is manufactured at TSMC using the modern 4nm FinFET process.
AMD Ryzen 5 8645HS
► remove from comparison
The Ryzen 5 8645HS is an upper mid-range processor (APU) of the Hawk Point family. This isn't an entirely new chip; instead, the 8645HS is a rebadged Ryzen 5 7640HS with higher clock speeds on the Ryzen AI NPU. The 8645HS was brought to life in Q4 2023 and it has 6 SMT-enabled Zen 4 cores (12 threads) running at 4.3 GHz to 5.0 GHz. The Radeon 760M iGPU is responsible for carrying out 3D calculations and similar duties.
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 chips are promised to deliver an up to 40% increase in generative AI performance over 7040 series APUs making apps like DaVinci Resolve and Adobe Photoshop even more powerful.
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 8645HS has 16 MB of L3 cache and a super-fast DDR5-5600 / LPDDR5x-7500 RAM controller. USB 4 (and thus Thunderbolt) is supported natively and so is PCIe 4. In fact, 20 PCIe 4 lanes are on offer; data transfer speeds of up to 7.8 GB/s will be possible provided a sufficiently fast NVMe SSD is used.
Systems powered by this Ryzen 5 series chip are expected to run 64-bit Windows 11, 64-bit Windows 10, or Linux. Please note that the APU is not overclockable and neither will you be able to replace it with a faster one as it gets soldered to the motherboard permanently (FP7, FP7r2, FP8 socket interfaces).
Performance
Since the 8645HX is an 7640HS in disguise, it is safe to expect the APU to be about as fast as the Ryzen 9 5900HX, Ryzen 7 6800H, Ryzen 7 7736U and also the Core i5-12500H, 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 760M has 8 CUs (512 shaders) running at up to 2,600 MHz. While this is not the best graphics adapter for gaming as it's only just fast enough for low quality settings and resolutions such as 1600 x 900, it will let you connect up to four SUHD 4320p monitors and it also HW-encodes and HW-decodes the most widely used video codecs such as AV1, HEVC and AVC without breaking a sweat.
Power consumption
The 8645HS has a long-term power limit (default TDP) of 35 W to 54 W, giving laptop makers a choice between improving battery life and giving the system they are working on more oomph. Either way, an active cooling solution is a must for any system powered by the chip.
This Ryzen 5 series APU is built with TSMC's 4 nm process for high, as of late 2023, energy efficiency.
