AMD Ryzen 5 7545U vs AMD Ryzen 7 5800 Comparison

The AMD Ryzen 5 7545U and AMD Ryzen 7 5800 represent two distinct design philosophies from AMD, separated by architecture, process node, and market segment. The recorded data shows a decisive overall winner in raw compute: the Ryzen 7 5800 wins 15 of the 17 shared benchmark comparisons, while the Ryzen 5 7545U takes the remaining two. The Ryzen 7 5800 posts an average benchmark score of 27535, while the Ryzen 5 7545U averages 26849. This places the Ryzen 7 5800 in the company of the Intel Core Ultra 5 125H (27507, 0.1 delta) and the Intel Core i5-12600K (27578, -0.2 delta), while the Ryzen 5 7545U sits near the Intel Core i7-1370P (26900, -0.2 delta) and the AMD Ryzen AI 7 445 (26936, -0.3 delta). Both processors hold the 79th percentile in the database's global ranking, yet their performance profiles diverge sharply across specific workloads.

Head-to-Head Benchmarks

The Ryzen 7 5800 establishes its dominance across the entire Cinebench suite. In Cinebench R23 multi-core, it scores 21953 against 17253, a 21.4% lead. The single-core R23 test shows a similar 21.4% gap, 3099 versus 2435. This pattern repeats in Cinebench R20 multi-core (9220 vs 7246, a 21.4% gap) and single-core (1301 vs 1022, a 21.4% gap). Even the older Cinebench R15 tests show the same margin: multi-core 2212 vs 1739 (21.4% gap) and single-core 312 vs 245 (21.5% gap). The consistency of this 21.4% delta across all Cinebench versions indicates a fundamental throughput advantage for the Ryzen 7 5800.

The largest deltas appear in Passmark integer math, where the Ryzen 7 5800 scores 92843 against 60206, a 35.2% advantage. Passmark find prime numbers shows a 38.2% gap (110 vs 68), the single largest margin in the entire comparison. Data encryption favors the Ryzen 7 5800 by 29.1% (20021 vs 14202), and floating point math by 28.8% (51588 vs 36754). Data compression is 24.7% higher on the Ryzen 7 5800 (316429 vs 238345). Extended instructions are 16.1% higher (21297 vs 17865). The multithread Passmark score is 25823 vs 20298, a 21.4% gap.

The Ryzen 5 7545U wins the Passmark single-thread test, scoring 3673 against 3393, an 8.3% advantage. This is its only head-to-head win, and it does not extend to Cinebench single-core tests, where the Ryzen 7 5800 leads by 21.4% to 21.5%. The closest margins are in Passmark physics (1141 vs 1057, a 7.4% lead for the Ryzen 7 5800) and random string sorting (32998 vs 30358, an 8% lead). These two tests show the Ryzen 5 7545U is competitive in specific latency-sensitive or lightly threaded operations, but the overall trend is unmistakable.

Where Each One Wins

The Ryzen 7 5800 is the clear choice for heavily threaded workloads. Rendering, data compression, encryption, and mathematical calculations all show substantial leads. The 21.4% advantage across all Cinebench multi-core versions indicates consistent scaling from its 8 cores and 16 threads. The 35.2% lead in integer math and 38.2% lead in prime number finding highlight its strength in CPU-bound computational tasks. For users running video encoding, 3D rendering, or scientific simulations, the Ryzen 7 5800 delivers a decisive performance edge.

The Ryzen 5 7545U wins specifically in the Passmark single-thread metric. This suggests a strong single-core burst capability, but the Cinebench single-core results contradict this, showing a 21.4% deficit. The data indicates the Ryzen 5 7545U's single-thread win is isolated to that specific Passmark test, which may measure different aspects of instruction handling. For systems without a discrete graphics card, the Ryzen 5 7545U includes a Radeon 740M integrated GPU, while the Ryzen 7 5800 has no integrated graphics. This is a functional advantage for the mobile chip in basic display tasks and systems that cannot accommodate a separate GPU.

The Ryzen 5 7545U operates at a 28 W TDP, while the Ryzen 7 5800 operates at 65 W. This makes the Ryzen 5 7545U more suitable for power-constrained mobile environments, though the benchmark scores reflect the higher power budget of the desktop part. The Ryzen 5 7545U also supports DDR5 memory with a bandwidth of 89.6 GB/s, compared to the DDR4 and 51.2 GB/s of the Ryzen 7 5800, which can benefit memory-sensitive applications despite the core count disadvantage.

Architecture Differences

The Ryzen 5 7545U uses the Zen 4 architecture on the Phoenix2 codename, while the Ryzen 7 5800 uses Zen 3 on Vermeer. The process node differs: 4 nm for the Ryzen 5 7545U versus 7 nm for the Ryzen 7 5800, both fabricated by TSMC. Transistor counts differ dramatically. The Ryzen 5 7545U packs 20,900 million transistors on a 137 mm² die, while the Ryzen 7 5800 has 4,150 million transistors on a 74 mm² die. The higher transistor density of the Ryzen 5 7545U enables its integrated graphics and newer memory controller, but the Ryzen 7 5800 compensates with a larger physical core count.

Cache hierarchies also diverge. The Ryzen 5 7545U's L2 cache is 1 MB per core, double the 512 KB per core of the Ryzen 7 5800. However, the Ryzen 7 5800 has a larger shared L3 cache at 32 MB, compared to 16 MB on the Ryzen 5 7545U. This larger L3 cache is a significant factor in the Ryzen 7 5800's multi-threaded performance, as it reduces memory latency for frequently accessed data across all cores. The Ryzen 5 7545U's smaller L3 cache is partially offset by its faster DDR5 memory bandwidth.

Memory support diverges: the Ryzen 5 7545U uses DDR5 with a bandwidth of 89.6 GB/s, while the Ryzen 7 5800 uses DDR4 with 51.2 GB/s. Both support ECC memory and dual-channel buses. PCIe connectivity differs: the Ryzen 5 7545U provides 14 Gen 4 lanes, while the Ryzen 7 5800 provides 20 Gen 4 lanes. The Ryzen 5 7545U is built for the AMD Socket FP7, while the Ryzen 7 5800 uses AMD Socket AM4. The Ryzen 5 7545U is a mobile part, while the Ryzen 7 5800 is a desktop part, which explains the socket and power differences.

The Verdict

The data clearly favors the AMD Ryzen 7 5800 for raw performance. It wins 15 of 17 head-to-head comparisons, including every Cinebench test and the majority of Passmark workloads. Its average benchmark score of 27535 is higher than the 26849 of the Ryzen 5 7545U. The Ryzen 7 5800's 8 cores, 16 threads, and 32 MB of L3 cache provide a substantial advantage in multi-threaded and compute-intensive tasks, making it the superior choice for desktop users who prioritize performance over power efficiency.

The Ryzen 5 7545U is the better fit for mobile platforms. It offers a lower 28 W TDP, integrated Radeon 740M graphics, and a newer 4 nm process. Its single Passmark single-thread win (3673 vs 3393) shows a specific strength, but it cannot overcome the Ryzen 7 5800's core count and cache advantage in sustained multi-threaded tasks. The Ryzen 5 7545U also supports faster DDR5 memory, which may benefit certain workloads, but the overall compute deficit remains.

Users building a desktop system with a discrete GPU should choose the Ryzen 7 5800. Users needing an integrated GPU for a compact or mobile system should choose the Ryzen 5 7545U. The Ryzen 7 5800's unlocked multiplier also allows overclocking, a feature absent on the Ryzen 5 7545U. The verdict is straightforward: the Ryzen 7 5800 wins on performance, while the Ryzen 5 7545U wins on platform flexibility and power efficiency.
