AMD Ryzen 5 7545U vs AMD Ryzen 5 7600 Comparison

The AMD Ryzen 5 7545U and AMD Ryzen 5 7600 are both six-core, twelve-thread Zen 4 processors, but they target entirely different segments. The 7545U is a mobile chip with a 28 W TDP, while the 7600 is a desktop part with a 65 W TDP. Benchmark results show a clear split: the 7600 wins 13 of the 15 head-to-head comparisons, while the 7545U wins only 2, but those 2 wins are in the Cinebench R23 suite. The average benchmark scores are close, at 26849 for the 7545U and 26324 for the 7600, yet the per-workload outcomes vary dramatically.

Where Each One Wins

The AMD Ryzen 5 7545U claims victory in Cinebench R23, both multi-core and single-core. In the multi-core test, it scores 17253 against the 7600's 12735, a 35.5% advantage. In single-core, it posts 2435 versus 1852, a 31.5% lead. These are substantial margins, and they indicate that the mobile chip's boost behavior and memory configuration can produce superior results in this specific rendering workload.

The AMD Ryzen 5 7600 dominates nearly everything else. It wins all PassMark tests: data compression (304942 vs 238345, 21.8% ahead), data encryption (17704 vs 14202, 19.8% ahead), extended instructions (23071 vs 17865, 22.6% ahead), find prime numbers (200 vs 68, 66% ahead), floating point math (48107 vs 36754, 23.6% ahead), integer math (80581 vs 60206, 25.3% ahead), multithread (27058 vs 20298, 25% ahead), physics (1776 vs 1057, 40.5% ahead), random string sorting (35904 vs 30358, 15.4% ahead), and single thread (3910 vs 3673, 6.1% ahead). It also wins the older Cinebench R15 tests: multi-core (2339 vs 1739, 25.7% ahead) and single-core (298 vs 245, 17.8% ahead).

The workload split is telling. The 7600 excels at sustained computational tasks like integer and floating point math, encryption, and physics simulations. The 7545U wins only in R23, which suggests its architecture can hit a higher performance peak in that particular benchmark. This is not a case of one processor being uniformly faster; it is a case of two different design priorities producing divergent results.

Architecture Differences

The two processors share the Zen 4 architecture, but they are built on different nodes and have different physical characteristics. The 7545U uses a 4 nm process from TSMC, while the 7600 uses a 5 nm process. The mobile chip has 20,900 million transistors on a 137 mm² die, whereas the desktop chip has 6,570 million transistors on a 71 mm² die. This is a significant difference in transistor density, reflecting the different design goals.

Both have 6 cores and 12 threads, with 64 KB L1 cache per core and 1 MB L2 cache per core. The L3 cache differs: the 7545U has 16 MB shared, while the 7600 has 32 MB shared. That extra L3 cache on the desktop part likely contributes to its strong PassMark performance, particularly in data compression and encryption.

The sockets are different as well. The 7545U uses AMD Socket FP7, a mobile package, while the 7600 uses AMD Socket AM5, a desktop socket. Memory support is DDR5 dual-channel for both, but the 7545U has a higher memory bandwidth at 89.6 GB/s versus 83.2 GB/s for the 7600. Both support ECC memory. PCIe connectivity differs: the 7545U offers Gen 4 with 14 lanes, while the 7600 offers Gen 5 with 24 lanes. The integrated graphics differ: the 7545U has a Radeon 740M, while the 7600 has a generic Radeon Graphics solution.

Clock speeds also differ. The 7545U has a base clock of 3.20 GHz and a boost clock of 4.90 GHz. The 7600 has a base clock of 3.80 GHz and a boost clock of 5.10 GHz. Despite the higher clocks on the desktop part, the 7545U wins R23, which indicates that clock speed alone does not determine benchmark outcomes.

Head-to-Head Benchmarks

The largest win for the 7600 is in PassMark find prime numbers, where it scores 200 versus 68, a 66% advantage. This is a massive gap and suggests the desktop chip's higher sustained clocks and larger cache are decisive for this integer-heavy workload. The physics test shows a 40.5% lead for the 7600, with 1776 versus 1057, which is another strong indicator of its computational muscle.

The 7545U's wins are equally striking. In Cinebench R23 multi-core, it leads by 35.5%, scoring 17253 against 12735. In single-core R23, it leads by 31.5%, with 2435 versus 1852. These are not minor edges; they are dominant margins that flip the expected outcome based on TDP and clock speed. The mobile chip appears to have a more efficient boost algorithm or better thermal headroom in that particular test.

The PassMark single-thread tests show a narrower gap. The 7600 scores 3910 versus 3673, a 6.1% lead. This is the closest margin among the 7600's wins, indicating that the 7545U is nearly competitive in single-threaded PassMark workloads. The random string sorting test shows a 15.4% lead for the 7600, with 35904 versus 30358, which is moderate.

The R15 results favor the 7600: multi-core 2339 versus 1739 (25.7% ahead) and single-core 298 versus 245 (17.8% ahead). These older benchmarks align more closely with the PassMark results, suggesting that the R23 outcome for the 7545U is an outlier rather than a general trend.

The Verdict

The data supports a clear decision for most users. The AMD Ryzen 5 7600 is the stronger processor for general computational tasks. It wins 13 of 15 head-to-head benchmarks, including all PassMark tests and Cinebench R15. Its 66% lead in prime number finding, 40.5% lead in physics, and 25% lead in multithread PassMark show that it handles sustained, varied workloads with more authority. The larger 32 MB L3 cache and higher 5.10 GHz boost clock are likely contributors to this advantage.

The AMD Ryzen 5 7545U is not without merit. Its wins in Cinebench R23, with a 35.5% multi-core lead and a 31.5% single-core lead, are impressive. For users who specifically rely on R23 as their primary benchmark, this mobile chip outperforms the desktop part. Its 4 nm process and 89.6 GB/s memory bandwidth may give it an edge in certain memory-sensitive rendering tasks.

The average benchmark scores are nearly identical, with the 7545U at 26849 and the 7600 at 26324, a difference of only 525 points. This means that for an average workload mix, the two are comparable. However, the distribution of wins matters. The 7600 provides more consistent performance across a wider range of tests, while the 7545U appears specialized for R23.

Users with a desktop build should choose the 7600. Its Gen 5 PCIe with 24 lanes and unlocked multiplier offer additional flexibility for expansion and overclocking. The 7545U, with its mobile socket and Gen 4 PCIe, is designed for laptops and compact systems, where its lower TDP is a primary advantage.
