► remove from comparison![AMD R5 7545U](fileadmin/_processed_/a/2/csm_7040_Angle_3_161633f8ac.png)
The AMD Ryzen 5 7545U is a fast mid-range laptop processor of the Phoenix series. It offers 6 cores (hexa core) based on the Zen 4 architecture that supports hyperthreading (12 threads). The cores clock from 3.2 (base) up to 4.9 GHz (single core boost). The processor includes 6 MB L2 cache and 16 MB L3 cache.
Thanks to the new Zen 4 architecture and higher clock speeds, the R5 7545U is clearly faster than the old Ryzen 5 6600U (Zen 3, 6 cores, 4.5 GHz). Compared to the similar 7640U, the 7545U offers a lower base clock and a slower iGPU. Compared to the similar Ryzen 5 7540U, the 7545U offers a higher clocked GPU and uses the smaller Zen 4c cores for 4 of the 6 CPU cores.
The chip integrates a modern and fasts RDNA 3 graphics card (iGPU) called Radeon 740M with 4 of the 12 CUs and 2.5 GHz clock speed. Furthermore, the Phoenix series include a video engine with AV1 de- and encoding, 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 new Xilinx FPGA based XDNA AI accelerator (Ryzen AI) is not included in the 7545U.
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 (28 Watt default).
Intel Core i5-13450HX
► remove from comparison![Intel i5-13450HX](fileadmin/_processed_/8/d/csm_Intel_Raptor_Lake_86e1e40c2a.jpg)
The Intel Core i5-13450HX is a fast mid-range mobile processor of the Raptor Lake series. Is was announced in early 2023. The CPU integrates 6 fast Raptor Cove performance cores (P-cores) with HyperThreading and 4 Gracemont efficiency cores without HyperThreading. The P-Cores clock between 2.4 GHz (base) up to 4.6 GHz (single core boost, all-core 4.5 GHz). The smaller E-Cores clock between 1.8 and 3.4 GHz. All cores can access the combined 20 MB L3 cache (compared to the 36 MB of the i9 models).
Compared to Alder Lake, Raptor Lake offers improved P-Cores (Raptor Cove micro-architecture) with bigger Caches and more E-Cores (same Gracemont micro-architecture). Furthermore, the chip supports faster DDR5 memory (up to 5600 MHz for the 13980HX, but only 4800 MHz for the i5).
Performance
While we have not tested a single system built around the 13450HX as of August 2023, we have tested several systems featuring the Core i5-12600K, a CPU with very similar specs (six P-cores mated to four E-cores, both running at insignificantly faster clock speeds than what the 13450HX has). Based on that, we expect the 13450HX to be 10% to 15% behind the Ryzen 7 7840HS and the Ryzen 9 7940HS, as far as multi-thread benchmark scores are concerned.
Your mileage may vary depending on how competent the system's cooling solution is and how high the CPU power limits are.
Power consumption
The chip's "minimum assured" power consumption sits at 45 W. Its Turbo power consumption is not supposed to go over 157 W and its "base" power consumption is supposed to be around 55 W. Most laptop makers will probably go for a value much higher than 55 W to extract as much performance out of the chip as possible.
The i5-13450HX is built with Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.
AMD Ryzen 5 PRO 7640U
► remove from comparison![AMD R5 PRO 7640U](fileadmin/_processed_/a/2/csm_7040_Angle_3_161633f8ac.png)
The AMD Ryzen 5 PRO 7640U is a fast mid-range laptop processor of the Phoenix series. It offers 6 cores (hexa core) based on the Zen 4 architecture that supports hyperthreading (12 threads). The cores clock from 3.5 (base) up to 4.9 GHz (single core boost). The processor includes 6 MB L2 cache and 16 MB L3 cache.
Compared to the consumer Ryzen 5 7640U, the PRO models offer additional security, manageability, and reliability features designed for professional users and workstation environments.
Thanks to the new Zen 4 architecture and higher clock speeds, the R5 PRO 7640U is clearly faster than the old Ryzen 5 6600U (Zen 3, 6 cores, 4.5 GHz). Compared to the similar 7640HS, the U-series offers a lower TDP and slightly lower core clocks.
The chip integrates a modern and fasts RDNA 3 graphics card (iGPU) called Radeon 760M with 8 of the 12 CUs and 2.6 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 35 and 45 Watt.
