Intel Celeron 847

Intel Celeron 847 is a dual-core mobile processor from Intel’s Sandy Bridge generation, built on a 32 nm process with 504 million transistors on a 131 mm² die. It operates at a fixed 1100.00 MHz base clock with no boost capability, and it is an end-of-life part designed for the Intel BGA 1023 socket. The chip includes 64 KB of L1 cache per core, 256 KB of L2 per core, and 2 MB of shared L3 cache, alongside dual-channel DDR3 memory support and integrated Intel HD (Sandy Bridge) graphics. Its market segment is mobile, and it carries a 17 W TDP, positioning it as a low-power entry point in Intel’s lineup. The data shows a 50th percentile ranking among all CPUs, indicating a mid-pack standing when viewed against the full spectrum of processors, though the average benchmark score of zero and an absence of rival entries make direct quantitative positioning sparse.

Benchmark Performance

The Intel Celeron 847 presents a unique case in the benchmark database: its `avgBenchmarkScore` is recorded as zero, and its `nearestRivals` list is empty. This absence of comparative scores means that no percentage deltas can be calculated against direct competitors from the provided data. The `percentileVsAllCpus` value of 50 places it exactly at the median of all CPUs tracked by the database, which is a statistical midpoint rather than a performance verdict. In practical terms, this score suggests that the Celeron 847 sits in the middle of the distribution when all processors are ranked, but the zero average score indicates that the chip either has not been subjected to the standard benchmark suite or that its results are not aggregated in the current dataset. Without rival scores, the benchmark performance must be interpreted cautiously: the 50th percentile is a positional marker, not a measure of computational throughput. The dual-core, dual-thread configuration with a 1.10 GHz base clock would inherently limit raw performance, but the data does not provide any absolute score to confirm this expectation. The lack of a boost clock further means that all workloads run at a single, fixed frequency, which is unusual in modern processors and likely contributes to modest sustained performance in any multithreaded or single-threaded task. The benchmark section therefore relies entirely on the percentile field, which indicates a balanced position across the database, though the zero score tempers any claim of measured capability.

Power and Thermals

The TDP for the Intel Celeron 847 is 17 W, a figure that classifies it firmly in the ultra-low-power segment for mobile processors. This thermal design power is indicative of a chip that can be cooled by a passive heatsink or a very small, low-speed fan, as typical for thin-and-light laptops or embedded systems from the Sandy Bridge era. The 32 nm process node, while not cutting-edge by modern standards, was efficient enough to allow such a low TDP with two active cores. The absence of a boost clock means the processor never exceeds its 1100.00 MHz base frequency, which reduces peak power draw and thermal spikes; the chip operates at a constant thermal load. The integrated Intel HD (Sandy Bridge) graphics share the same thermal envelope, which is a consideration for system designers because GPU load adds to the 17 W budget. Cooling requirements are modest: a basic heatpipe and small fan assembly would suffice, and the low TDP allows for fanless designs in some chassis, though the data does not specify any particular cooler tier. The 17 W figure is the sole thermal metric provided, and it implies that the Celeron 847 is suited for devices where battery life and low heat output are prioritized over performance. In a benchmark context, this low TDP means that thermal throttling is unlikely to be a factor in sustained workloads, as the chip simply does not generate enough heat to overwhelm even a minimal cooling solution.

Single-Thread vs Multi-Thread Behavior

With 2 cores and 2 threads, the Intel Celeron 847 has no hyper-threading, meaning it can execute exactly two threads concurrently. The base clock of 1100.00 MHz applies to both cores, and the absence of a boost clock means there is no single-thread turbo headroom. This configuration has a direct impact on workload behavior: single-threaded tasks run at the same 1.10 GHz as multi-threaded tasks, so there is no frequency advantage for lightly threaded applications. The 2 MB shared L3 cache is small by modern standards, which may limit performance in workloads that require frequent data reuse across cores. In multi-threaded scenarios, the processor can utilize both cores, but the low clock speed and lack of SMT mean that scaling from one to two threads is linear in terms of core count but not in efficiency, the shared cache and memory bus are potential bottlenecks. For real-world use, this split suggests that the Celeron 847 is adequate for basic productivity tasks like web browsing or document editing, which are often single-threaded, but it will struggle with modern multi-threaded applications that expect higher frequencies and more cores. The data shows no separate single-thread or multi-thread scores, so the behavioral analysis is derived from the core/thread count and clock speed. The fixed 1.10 GHz clock is the key differentiator: many processors offer a higher single-core boost, but this chip does not, so single-thread performance is identical to multi-thread performance per core. This makes the Celeron 847 predictable but unremarkable in both domains, with the 50th percentile ranking suggesting it is neither a standout nor a laggard in the aggregate.

How It Compares

The `nearestRivals` array is empty in the FACT PACK, which means there are no direct comparison points from the database for the Intel Celeron 847. This absence of rivals is notable because it prevents any percentage-based analysis against similar low-power dual-core processors. In the absence of named competitors, the only available comparison is the `percentileVsAllCpus` of 50, which places it at the median of all CPUs. This implies that, while there are no specific rivals listed, the Celeron 847 sits in the middle of the performance distribution when all processors are considered. The zero average benchmark score further complicates direct comparison, as there is no numerical baseline to measure against. For a user evaluating this chip, the lack of rival data means that positional analysis is limited to the percentile field, which is a relative ranking rather than a head-to-head delta. The chip’s low clock speed and dual-core design would suggest it is outclassed by more modern low-power parts like Intel Atom or Celeron N-series, but those are not listed in the FACT PACK. Therefore, the comparison section must state clearly that no rival data exists, and the only quantitative statement is the 50th percentile, which indicates a median position in the database’s overall CPU ranking. Without rival scores or deltaPct values, no further comparative claims can be made.

FAQ

Q: What is the processor’s position relative to all CPUs in the database?

A: The Intel Celeron 847 has a `percentileVsAllCpus` of 50, meaning it sits exactly at the median of all processors tracked by the database, with an average benchmark score of zero.

Q: Does the processor support boost clocks?

A: No, the `boostClock` field is null, and the `baseClock` is fixed at 1100.00 MHz, so the chip operates at a constant frequency without any turbo or boost capability.

Q: How many cores and threads does the Celeron 847 have?

A: It has 2 cores and 2 threads, with no hyper-threading support, as indicated by the `threads` field being equal to the `cores` field.

Q: What is the thermal design power, and what does it imply for cooling?

A: The TDP is 17 W, which is a low-power figure that implies modest cooling requirements, such as a small fan or passive heatsink, suitable for thin-and-light mobile devices.

Q: What type of memory does this processor support?

A: It supports DDR3 memory in a dual-channel configuration, with ECC memory not supported, according to the `memorySupport` and `eccMemory` fields.

Q: Is the processor still in production?

A: No, the production status is listed as “End-of-life,” and the release date is 2011-06-18, indicating it is a legacy part from the Sandy Bridge generation.

Q: Does the processor have an unlocked multiplier for overclocking?

A: No, the `multiplierUnlocked` field is false, so the clock frequency cannot be adjusted by the user.
