MagyarAMD Ryzen 5 PRO 7540U vs AMD Ryzen 9 7950X3D
AMD Ryzen 5 PRO 7540U
► remove from comparison
The AMD Ryzen 5 PRO 7540U 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 7540U, 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 7540U is clearly faster than the old Ryzen 5 6600U (Zen 3, 6 cores, 4.5 GHz). Compared to the similar PRO 7640U, the 7540U offers a lower base clock and a slower iGPU.
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, 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.
AMD Ryzen 9 7950X3D
► remove from comparison
The AMD Ryzen 9 7950X3D is a high-end desktop processor of the Raphael series with 16 cores and SMT (Simultaneous Multithreading), which means it can process up to 32 threads simultaneously. With the release in February 2023, the Ryzen 9 7950X3D is AMD's fastest consumer processor and the new top model of the 7000 series. The CPU cores clock from 4.2 GHz (base clock) up to 5.7 GHz (single core Turbo). In addition, the AMD Ryzen 9 7950X3D has a CCD with 8 cores that can access the fast 3D V-cache, which offers considerably more gaming performance.
The performance of the AMD Ryzen 9 7950X3D is consistently excellent in all applications tested. In addition, AMD was again able to increase the single-thread performance compared to the non-X3D models. Nevertheless, the lower base clock compared to the AMD Ryzen 9 7950X means that a small drop in multi-thread performance has to be accepted.
The internal structure of the processor is comparable to the previous AMD Ryzen 9 7950X. The AMD Ryzen 9 7950X3D is also still based on the chiplet design consisting of two CCD clusters with 8 cores each. However, the two CCDs differ significantly from each other because one offers the fast 3D V-Cache, which primarily improves gaming performance. In testing, the AMD Ryzen 9 7950X3D was able to put the Intel Core i9-13900K in second place and is the fastest gaming CPU on the market at the time of testing.
The AMD Ryzen 9 7950X3D is an extremely energy-efficient CPU with up to 162 watts (PPT) and is significantly more frugal under load than an AMD Ryzen 9 7950X (max. 230 watts).
