Intel Core M-5Y10c

The Intel Core M-5Y10c is a 2-core, 4-thread mobile processor from the Broadwell-Y generation, built on Intel’s 14 nm process node. It operates with a base clock of 800.00 MHz and a boost clock of 2000.00 MHz, aimed at fanless, ultra-portable devices. Its benchmark profile places it at the 11th percentile among all CPUs, with an average benchmark score of 557, indicating a low-power part designed for basic productivity rather than heavy compute.

Who Should Consider It

The data suggests this chip suits users whose workloads are light, intermittent, and latency-tolerant. In Cinebench R23 multi-core, it scores 1619, which is modest but workable for document editing, web browsing, and video playback. The single-core score of 228 in Cinebench R23 indicates that everyday tasks that rely on one thread — like opening applications or scrolling through complex web pages — will feel responsive enough for casual use, but not snappy under sustained load.

For office productivity, the 4-thread design (2 cores with Hyper-Threading) can handle spreadsheet recalculation, email clients, and presentation software without significant strain, provided the user does not multitask heavily. The Cinebench R20 multi-core score of 679 and single-core score of 95 reinforce this: the part is roughly four times slower in multi-threaded rendering than a mainstream desktop chip, but such rendering is not its intended role.

Creative workloads, such as photo editing in layers or 1080p video encoding, are possible but slow. The Cinebench R15 multi-core score of 162 suggests that even light rendering tasks will take noticeable time. Gamers should avoid this processor for anything beyond casual 2D titles or very old 3D games; its integrated Intel HD 5300 graphics and low clock speeds (max 2000.00 MHz) are not suited for modern 3D engines. Instead, this is a companion for a secondary laptop or a thin-and-light notebook where battery life and silence matter more than raw speed.

Single-Thread vs Multi-Thread Behavior

The split between single-core and multi-core scores reveals a processor that scales reasonably well with additional threads, but the absolute numbers are low. In Cinebench R23, the multi-core score of 1619 is roughly 7.1 times the single-core score of 228, which is expected for a 2-core/4-thread part — Hyper-Threading provides a modest boost, but the physical core count limits scaling. In Cinebench R20, the multi-core score of 679 is about 7.1 times the single-core score of 95, showing consistent scaling across benchmark versions.

This behavior implies that multi-threaded applications, such as file compression or batch photo processing, will utilize all four threads, but the performance ceiling is low because each core is slow. The base clock of 800.00 MHz is unusually low, suggesting the chip spends most of its time in a power-saving state; the boost clock of 2000.00 MHz is reached only for short bursts. Real-world workloads that alternate between idle and active — like checking email or reading PDFs — will see the processor ramp up and down, delivering adequate responsiveness without sustained heat generation. Conversely, any task that holds all threads busy for minutes (e.g., video transcoding) will cause the chip to settle at a lower clock, further reducing throughput.

How It Compares

Intel Core i3-3130M: The data shows a deltaPct of 0, meaning the two processors have identical average benchmark scores of 557. However, the i3-3130M is a much older, higher-power part from the Ivy Bridge era, while the M-5Y10c achieves the same result with a 5 W TDP. This suggests the M-5Y10c is far more efficient per watt, but the i3-3130M likely sustains its performance longer under load due to a higher thermal envelope.

Intel Atom x5-E3940: This rival also scores 557, with a deltaPct of -0.1, making it essentially tied. The Atom is a quad-core, low-power part (typically 6-12 W), so the comparison highlights that the M-5Y10c’s two faster cores can match four weaker Atom cores in mixed workloads. For single-threaded tasks, the M-5Y10c’s higher boost clock (2000.00 MHz vs. the Atom’s lower frequency) gives it an edge, but for heavily parallel workloads, the Atom’s extra cores might narrow the gap.

Intel Xeon E5507: The Xeon E5507 matches the average score of 557 with a deltaPct of 0.1. This is a server-oriented processor from 2009, featuring 4 cores (no Hyper-Threading) and a much higher TDP. The fact that a 2014 ultra-mobile chip matches a server part from five years earlier underscores how far mobile efficiency has come, but also warns that the Xeon’s older architecture is not a meaningful performance reference for modern software.

Intel Celeron G1850: With a deltaPct of 0.1 and an average score of 557, the Celeron G1850 is again a statistical tie. This is a desktop dual-core part (no Hyper-Threading) with a significantly higher clock speed and TDP. The M-5Y10c’s ability to match it while consuming a fraction of the power indicates that the Broadwell architecture’s IPC improvements offset the lower clock speeds, but the Celeron would still be preferable for sustained workloads that don’t benefit from Hyper-Threading.

FAQ

Q: Is this processor suitable for everyday web browsing and office work?

A: Yes, benchmark results indicate it scores 228 in Cinebench R23 single-core, which is adequate for basic tasks like web browsing, email, and word processing, though it will feel slower than modern mainstream chips.

Q: How does it handle multitasking with many open applications?

A: The 4 threads (2 cores) allow some multitasking, but the low multi-core scores (1619 in R23, 679 in R20) mean that heavy simultaneous workloads, like video conferencing while compiling code, will cause noticeable slowdowns.

Q: Can it play games?

A: The integrated Intel HD 5300 graphics and low boost clock (2000.00 MHz) are not designed for gaming. Only very light or older 2D titles are feasible; any modern 3D game would be unplayable.

Q: How does its performance compare to a modern low-end laptop CPU?

A: The 11th percentile ranking among all CPUs indicates it is in the bottom tier. Most current budget processors, even Atom-class parts, will match or exceed its scores in multi-threaded tasks.

Q: Is the 14 nm process a benefit?

A: Yes, the 14 nm node allows a 5 W TDP, which enables fanless designs and long battery life, but the trade-off is lower sustained performance compared to larger, higher-power chips.

Q: What is the difference between its base and boost clocks?

A: The base clock is 800.00 MHz, which is very low for idle efficiency, while the boost clock of 2000.00 MHz provides short bursts of higher performance. Sustained loads will likely see clocks drop below boost due to thermal and power limits.

Power and Thermals

The TDP is 5 W, which classifies this processor as an ultra-low-power part. This is among the lowest TDPs for any x86 CPU, enabling designs without active cooling — a fanless chassis is typical. The 14 nm process node and small die size of 50 mm² contribute to this efficiency, as does the Broadwell-Y architecture’s focus on idle power reduction. The base clock of 800.00 MHz is a clear indicator that the chip spends most of its time at very low power, only ramping to 2000.00 MHz when needed.

Thermals are a direct consequence of the TDP: a simple heatsink or even a heat spreader attached to the chassis is sufficient to keep temperatures in check. There is no need for a high-end air cooler or liquid cooling; the data implies that any passive cooling solution designed for thin laptops will suffice. However, users should expect that prolonged multi-threaded workloads will cause the chip to throttle, as the 5 W envelope limits the maximum sustained clock. For workloads like Cinebench R23 multi-core (scoring 1619), the processor will likely hit the power limit quickly and reduce clocks, making the boost clock of 2000.00 MHz a transient state rather than a sustained capability.

Platform and Compatibility

This processor uses the Intel BGA 1234 socket, which means it is soldered to the motherboard and not upgradeable. It belongs to the Broadwell-Y generation, with the codename Broadwell-Y, and is part of the Core M family. Memory support is DDR4, although the memory bus and bandwidth are not specified in the data; this limits users to the memory configuration chosen by the device manufacturer. ECC memory is not supported, which is expected for a consumer mobile chip.

PCIe specifications are not listed, so the expansion capabilities are unknown, but given the mobile segment and BGA socket, users will be limited to whatever the laptop’s motherboard provides — typically a few PCIe lanes for an M.2 SSD and wireless card. The integrated graphics is Intel HD 5300, which handles video decode and display output but offers no discrete GPU support beyond that. The production status is "Active," and the release date is 2014-10-26, so this is an older part, but still in production for legacy designs. The upgrade path is essentially nonexistent: because it is BGA-soldered, users cannot swap in a faster CPU. The platform’s value lies in its pre-configured integration, not in future expandability.

Benchmark Performance

The average benchmark score of 557 places this chip at the 11th percentile, meaning it outperforms only about 11% of all CPUs in the database. This is a definitive low-tier position. In Cinebench R23, the multi-core score of 1619 and single-core score of 228 show a wide gap; for context, the multi-core score is about 7.1 times the single-core score, which is typical for a 2-core/4-thread part. The Cinebench R20 results (multi-core 679, single-core 95) show a similar ratio of about 7.1, confirming that the scaling is consistent.

Compared to its nearest rivals, the M-5Y10c is statistically tied with all four: the Intel Core i3-3130M (deltaPct 0), Intel Atom x5-E3940 (deltaPct -0.1), Intel Xeon E5507 (deltaPct 0.1), and Intel Celeron G1850 (deltaPct 0.1). This means that in aggregate benchmark scores, they are indistinguishable. However, the deltaPct values are all within 0.1%, which is essentially noise. The real differences lie in workload behavior: the Atom x5-E3940 likely has more cores (4) but lower per-core performance, while the Celeron G1850 has higher clocks but fewer threads. The M-5Y10c’s advantage is its efficiency — matching these parts while consuming 5 W, versus the likely 35-65 W TDP of the i3-3130M, Xeon E5507, and Celeron G1850.

In single-threaded tests, the M-5Y10c’s boost clock of 2000.00 MHz is modest, but the Broadwell architecture’s IPC is strong enough to keep it competitive with older desktop parts. The Cinebench R23 single-core score of 228 is low in absolute terms, but it aligns with the processor’s positioning as a low-power mobile chip. Multi-threaded performance, as seen in the R20 score of 679, is adequate for light parallel tasks but will bottleneck in any serious rendering or compilation. The benchmark data collectively paints a picture of a processor that excels at energy efficiency and basic responsiveness, but falls far short of anything demanding. The 11th percentile ranking is a stark reminder that this is a niche product for specific ultra-mobile use cases, not a general-purpose workhorse.
