AMD Ryzen 5 7520C

The AMD Ryzen 5 7520C is a 4-core, 8-thread mobile processor built on TSMC’s 6 nm process using the Zen 2 architecture, code-named Mendocino. It targets the low-power laptop segment with a 15 W TDP and integrates Radeon 610M graphics. Its average benchmark score of 2127 places it at the 48th percentile of all CPUs, indicating a middle-of-the-road standing that is closely contested by a cluster of Intel rivals.

How It Compares

Against the Intel Xeon E-2224G, the Ryzen 5 7520C is effectively tied, with a deltaPct of -0.1%. The Xeon’s average score of 2128 is just one point higher than the 7520C’s 2127. This is a notable result because the Xeon is a desktop-class part, while the 7520C is a low-power mobile chip; the benchmark data shows the 7520C delivering comparable aggregate performance despite its different market positioning.

The Intel Xeon E5-2630L v3 presents a similar picture, with an average score of 2129 and a deltaPct of -0.1% relative to the 7520C. That rival is an older, high-core-count server processor, yet the 4-core 7520C matches its average output. This suggests the Zen 2 cores in the 7520C are efficient enough to compensate for a lower core count in mixed workloads.

The Intel Core i5-1145G7E, a direct competitor in the mobile space, scores 2131 on average, putting the 7520C behind by 0.2%. The margin is minuscule — four points — and falls within typical run-to-run variance. The 7520C’s lower TDP (15 W) versus the i5-1145G7E’s expected class does not translate into a meaningful performance deficit in the aggregate data.

The only rival the 7520C leads is the Intel Core i5-8259U, which averages 2115. The deltaPct here is +0.5%, meaning the 7520C is 12 points ahead. The i5-8259U is a 28 W part from an older generation, and the data indicates the 7520C’s newer architecture and process node help it edge out that chip despite a lower thermal envelope.

Single-Thread vs Multi-Thread Behavior

The Cinebench scores reveal a pronounced split between single-thread and multi-thread performance. In Cinebench R23, the 7520C scores 1038 single-core and 7355 multi-core. The multi-core figure is roughly 7.1 times the single-core score, which is close to the theoretical 8-thread scaling limit, suggesting the scheduler and thermals allow all cores to boost effectively under load.

In Cinebench R20, the single-core score is 435 and multi-core is 3089, a ratio of about 7.1 as well. The consistency across R20 and R23 indicates the scaling behavior is stable across workloads. The R15 results show 104 single-core and 741 multi-core, a ratio of 7.1 again, reinforcing the pattern.

For real-world workloads, this means the 7520C behaves predictably: lightly threaded tasks like web browsing or office applications will rely on the 4.30 GHz boost clock, while heavily threaded tasks like video encoding will engage all 8 threads with near-linear gains. The 2.80 GHz base clock is relatively low, but the boost behavior compensates in bursty workloads. The multi-thread efficiency is strong for a 15 W part, as the scaling ratio indicates minimal thermal throttling during the benchmark runs.

Power and Thermals

The 7520C carries a 15 W TDP, classifying it as an ultra-low-power part designed for fanless or lightly cooled thin-and-light laptops. This TDP class implies that a basic heatpipe and small fan, or even a passive cooler in some chassis, is sufficient for sustained operation. The 6 nm process from TSMC helps keep power density low, which is critical for such a tight thermal budget.

The 100 mm² die size and 4 MB shared L3 cache are modest, and the lack of ECC memory support plus LPDDR5 memory interface (dual-channel, 88.0 GB/s bandwidth) align with a power-conscious design. The memory bandwidth is sufficient for the 4 Zen 2 cores, and the integrated Radeon 610M shares that bandwidth. The 15 W envelope means the CPU and iGPU must time-share power, so sustained all-core CPU load will reduce the headroom available for graphics. Cooling solutions for this class are typically low-profile; the data does not indicate any exotic cooling requirements.

The production status is Active, and the part uses AMD Socket FT6, which is a BGA package soldered to the motherboard. This reinforces the intended use in pre-built laptops rather than upgradeable desktop systems. The PCIe Gen 3 with 4 lanes (CPU only) further limits expansion, consistent with a thin client or entry-level Chromebook/Windows laptop.

A: The processor is manufactured by TSMC on a 6 nm process. The die size is 100 mm², and the architecture is Zen 2 with the codename Mendocino.

Benchmark Performance

The aggregate benchmark data places the 7520C at an average score of 2127, with a percentile rank of 48 among all CPUs. This means it sits just below the median, but the nearest rivals are extremely tightly packed — the spread between the lowest (i5-8259U at 2115) and highest (i5-1145G7E at 2131) is only 16 points, or 0.75%. The 7520C is thus in a dead heat with its direct competition.

Looking at the deltas, the 7520C trails the Intel Xeon E-2224G by 0.1%, trails the Intel Xeon E5-2630L v3 by 0.1%, trails the Intel Core i5-1145G7E by 0.2%, and leads the Intel Core i5-8259U by 0.5%. The differences are so small that they are unlikely to be perceptible in real applications; the data shows these four processors are functionally interchangeable in average performance.

The Cinebench R23 multi-core score of 7355 is the strongest result in the benchmark suite. For context, the R20 multi-core score of 3089 and R15 multi-core score of 741 follow the expected scaling curve between Cinebench versions. The single-core scores (1038 in R23, 435 in R20, 104 in R15) are modest, reflecting the 4-core design and the power constraints of the 15 W TDP.

The deltaPct values against the nearest rivals are all within ±0.5%, which is a remarkably tight cluster. The 7520C’s 0.5% lead over the i5-8259U is the largest margin any rival holds over another in this group. This indicates that for a buyer choosing among these four parts, the benchmark data offers no clear winner — the 7520C’s edge over the i5-8259U is real but negligible in magnitude, and its deficits against the other three are equally marginal.

The multi-thread scaling ratio of approximately 7.1x in all three Cinebench versions is a standout feature. This is close to the theoretical maximum of 8x for 8 threads, meaning the 7520C does not suffer from significant contention or thermal throttling during multi-threaded workloads. This is particularly impressive for a 15 W part, as many low-power CPUs show scaling ratios below 6x due to power limits. The data suggests that the 7520C can sustain full boost across all cores for the duration of the Cinebench multi-core tests.
