AMD Ryzen 9 7900 vs AMD Ryzen 5 PRO 7545U vs AMD Ryzen 5 PRO 7540U
AMD Ryzen 9 7900
► remove from comparison
The AMD Ryzen 9 79 00 is a high-end desktop processorfrom the Raphael series with 12 cores and hyperthreading (SMT), which means it can process up to 24 threads simultaneously. Launched in early 2023, the Ryzen 9 7900 is the fastest 12-core processor with 65 watts TDP.
The Ryzen 9 7900 clocks at 3.7 GHz base clock and reaches up to 5.4 GHz on one core in Turbo mode. This is also the difference to the higher clocked Ryzen 9 7900X.
At first glance, the internal structure of the processor has not changed fundamentally. The AMD Ryzen 9 7900 is still based on the chiplet design consisting of two CCD clusters, each containing a CCX with 8 cores. However, the manufacturing process has been scaled down to 5 nm, which ensures higher clock rates. There is also the IO die, which contains the memory controller and the iGPU, among other things. This is now manufactured in a 6 nm structure width.
The AMD Ryzen 9 7900 can impress in games thanks to the significantly improved IPC.
AMD Ryzen 5 PRO 7545U
► remove from comparison
The AMD Ryzen 5 PRO 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.
Compared to the consumer Ryzen 5 7545U, 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 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).
