AMD Ryzen 5 7545U vs AMD Ryzen 7 5700G Comparison

The AMD Ryzen 7 5700G and AMD Ryzen 5 7545U represent two very different philosophies: a desktop chip built for raw multi-threaded throughput versus a mobile processor engineered for efficiency and single-core speed. While both land at the 79th percentile among all CPUs, their benchmark profiles show a clear split in strengths. The 5700G takes the majority of wins (8 of 15 head-to-head tests), but the 7545U counters with decisive victories in the most modern workloads.

Head-to-Head Benchmarks

The most dramatic split appears in Cinebench. The Ryzen 7 5700G wins the Cinebench R15 multicore test with a score of 2107 against 1739 for the 7545U, a 21.2% advantage. But the tables turn completely in Cinebench R23. There, the 7545U posts 17253 versus 12830.5 for the 5700G — a 25.6% swing in the mobile chip’s favor. This inversion suggests the 7545U scales far better with the newer R23 benchmark’s workload characteristics.

Single-core results heavily favor the 7545U. In Cinebench R23 single-core, the 7545U hits 2435 versus 1494 for the 5700G, a commanding 38.6% lead. The gap narrows in Cinebench R15 single-core (245 vs 242.5, just 1% for the 7545U) and in PassMark single-thread (3673 vs 3283, a 10.6% edge). The 7545U also wins PassMark physics (1057 vs 999, 5.5% ahead) and PassMark find prime numbers (68 vs 59, 13.2% ahead).

The 5700G dominates the math-heavy PassMark suite. Its integer math score of 91541 crushes the 7545U’s 60206 — a 52% margin, the largest of any test. Floating point math also goes decisively to the desktop chip: 51296 vs 36754, a 39.6% win. Data encryption (20325 vs 14202, 43.1% ahead) and data compression (318262 vs 238345, 33.5% ahead) follow the same pattern. Extended instructions (21847 vs 17865, 22.3%) and multithread (24419 vs 20298, 20.3%) round out the 5700G’s advantages. Random string sorting is closer, with the 5700G winning 33384 vs 30358 at 10%.

Where Each One Wins

The Ryzen 7 5700G is the clear pick for any workload that leverages many cores simultaneously. Its 8-core/16-thread configuration gives it a natural advantage in integer math, encryption, compression, and general multithreaded throughput. The data shows a 20% or greater edge in six separate tests, making it the better engine for content creation, data processing, and compilation tasks that can use all available threads. The 43% encryption lead and 52% integer math lead are particularly striking for server-style or heavy productivity workloads.

The Ryzen 5 7545U wins where single-core performance and modern instruction efficiency matter. Its 38.6% Cinebench R23 single-core victory is the headline, but the PassMark single-thread win (10.6%) and physics score (5.5%) both point to superior per-thread execution. The 13.2% win in find prime numbers suggests better branch prediction or arithmetic efficiency. For everyday responsiveness, light gaming, and applications that still rely heavily on one or two threads, the 7545U’s profile is clearly stronger. Its Cinebench R23 multicore win (25.6% over the 5700G) also shows that in the newest rendering benchmark, the newer architecture more than compensates for its two fewer cores.

Architecture Differences

The two chips come from different worlds. The 5700G is a desktop part on AMD Socket AM4, built on TSMC’s 7 nm process with the Zen 3 architecture (codenamed Cezanne). It packs 10,700 million transistors into a 180 mm² die. The 7545U is a mobile part on AMD Socket FP7, using TSMC’s 4 nm process with the Zen 4 architecture (codenamed Phoenix2). It contains 20,900 million transistors on a smaller 137 mm² die — nearly double the transistor count in 24% less area.

Core counts differ: the 5700G has 8 cores and 16 threads, while the 7545U has 6 cores and 12 threads. Clock speeds tell a nuanced story. The 5700G has a higher base clock (3.80 GHz vs 3.20 GHz) but a lower boost clock (4.60 GHz vs 4.90 GHz). The 7545U’s higher boost explains its single-core dominance. Power envelopes are radically different: the 5700G runs at 65 W TDP, while the 7545U draws just 28 W — a 37 W difference that makes the mobile chip far more suitable for thin laptops.

Cache layouts are similar in L3 (16 MB for both, though the 7545U’s is shared while the 5700G’s is not specified as such), but L2 differs: 512 KB per core on the 5700G versus 1 MB per core on the 7545U. Memory support reflects their generations: the 5700G uses DDR4 with 51.2 GB/s bandwidth, while the 7545U uses DDR5 with 89.6 GB/s. The 7545U also supports ECC memory (the 5700G does not). PCIe is another generational jump: Gen 3 with 16 lanes on the desktop chip versus Gen 4 with 14 lanes on the mobile chip.

Integrated graphics differ as well: the 5700G has Radeon Vega 8, while the 7545U has Radeon 740M. The 5700G has an unlocked multiplier for overclocking; the 7545U does not. Release dates are nearly two years apart (April 2021 for the 5700G, November 2023 for the 7545U), which explains the architectural gap.

The Verdict

The data supports a clear split based on use case. Choose the AMD Ryzen 7 5700G if your priority is raw multi-threaded compute in a desktop system. Its 8-core/16-thread design delivers a 52% lead in integer math, a 43.1% lead in encryption, and a 39.6% lead in floating-point math over the 7545U. It also wins data compression by 33.5% and multithread by 20.3%. The 5700G’s 65 W TDP and unlocked multiplier make it a solid choice for a mainstream desktop build where power draw is secondary and overclocking is desired.

Choose the AMD Ryzen 5 7545U if you need modern single-core speed or are building a mobile system. Its 38.6% Cinebench R23 single-core advantage and 10.6% PassMark single-thread lead are decisive. The 7545U also wins Cinebench R23 multicore by 25.6%, proving that its Zen 4 architecture plus higher boost clock (4.90 GHz) can overcome a two-core deficit in modern rendering workloads. Its 28 W TDP, DDR5 support, and ECC capability make it the better fit for battery-powered devices and memory-sensitive applications.

Both chips sit at the 79th percentile of all CPUs and have nearly identical average benchmark scores (27051 for the 5700G, 26849 for the 7545U). The 5700G’s nearest rival is the Intel Core i9-9900K (0.2% behind), while the 7545U matches closely with the Intel Core i7-1370P (0.2% behind). The real differentiator is workload: desktop multithreading favors the 5700G; mobile efficiency and single-core tasks favor the 7545U.
