Intel Celeron 877

Intel Celeron 877 is a 32 nm mobile processor from the Sandy Bridge architecture family, with two cores and two threads. It runs at a 1400.00 MHz base clock, has no recorded boost clock, and integrates Intel HD (Sandy Bridge) graphics. The chip is built for the Intel BGA 1023 socket, supports dual-channel DDR3 memory, and is classified as a Mobile part. Its listed release date is 2012-06-30.

Platform and Compatibility

Compatibility begins with the socket. The data records Intel BGA 1023 as the only socket, and the market segment is Mobile, so this is a portable-platform processor rather than a desktop part. The architecture and codename are both Sandy Bridge, and the generation is listed as Celeron (Sandy Bridge). Intel is the listed foundry, and the manufacturing process is 32 nm. The silicon contains 504 million transistors on a 131 mm² die.

For memory, the Celeron 877 supports DDR3 with a dual-channel bus. ECC memory support is marked false, so the memory path is non-ECC. The fact pack does not include a memory bandwidth figure, so no throughput number can be cited from the data. PCIe support is also not specified in the record; there are no lane counts, revisions, or interface details to report. The upgrade path is therefore limited to the documented platform: the Intel BGA 1023 socket, the Sandy Bridge architecture, and the mobile segment. The fact pack lists no alternative socket compatibility and no other platform-level expansion information beyond the socket and memory controller.

Single-Thread vs Multi-Thread Behavior

The core layout is straightforward: two cores and two threads. Because the thread count is identical to the core count, there are no additional logical processors for the operating system to schedule. The base clock is 1400.00 MHz, and the fact pack does not list a boost clock. That absence matters: the processor’s only documented operating frequency is 1400.00 MHz. The multiplier is not unlocked either, so no user-directed frequency increase is recorded in the specification.

The cache hierarchy is split between per-core and shared resources. Each core has 64 KB of L1 cache and 256 KB of L2 cache. The two cores share a 2 MB L3 cache. For single-threaded work, the 1400.00 MHz base clock is the primary frequency constraint; there is no higher single-core boost recorded to accelerate lightly threaded tasks. For multi-threaded work, both cores can participate, but the workload is limited to exactly two threads. The shared 2 MB L3 cache gives both cores a common data pool, which can help when two threads access overlapping data. In practical terms, this is a small dual-core, dual-thread execution engine with a fixed base frequency and no boost headroom in the dataset.

Power and Thermals

The TDP is 17 W, and that is the only power figure in the fact pack. It places the Celeron 877 in a low-power class within the mobile segment. A 17 W envelope implies a modest thermal solution rather than a large cooler; the data does not include a cooler recommendation, but the TDP is the thermal reference point. The 32 nm process and the 504-million-transistor count are the available silicon design details. The integrated Intel HD (Sandy Bridge) graphics block shares the package, and its operation falls under the same 17 W TDP classification, though no separate graphics power figure is listed.

The fact pack contains no maximum temperature values, no thermal design current, and no cooling specification. The thermal analysis is therefore based on the TDP and the mobile platform context. The low TDP aligns with the mobile market segment and points to a lightweight cooling solution. The exact cooling tier is not defined in the data, but the power envelope is clearly a low-wattage design for portable systems.

How It Compares

The nearestRivals list for this processor is empty. There are no rival names, no comparison scores, and no deltaPct values in the fact pack. Because no nearest rivals are recorded, a per-rival comparison cannot be produced from the data. The only global position field is percentileVsAllCpus, which is 50. That percentile places the Celeron 877 at the midpoint of all CPUs in the database, but without named rivals there is no way to translate that midpoint into a specific margin against another processor.

The field name indicates that the comparison group is all CPUs, rather than a curated set of competitors. As a result, the percentile provides a neutral database position, not a measured performance ranking against a particular chip. The fact pack simply has no comparative material to work with.

Benchmark Performance

The benchmarks array in the fact pack is empty. No workload scores, synthetic results, or application-level measurements are present. The average benchmark score recorded for the part is 0. In a record with zero benchmark entries, that 0 is best understood as a placeholder rather than a measured result.

The percentileVsAllCpus field is 50, placing the CPU at the median of the global distribution. The pairing of a 0 average benchmark score with a 50th percentile is a signal of sparse data rather than a performance claim. There are no deltaPct values because nearestRivals is empty, so exact percentage comparisons against other CPUs cannot be made. No percentage advantages or deficits over any specific processor exist in the fact pack.

The benchmark summary is therefore a data-quality statement: the Celeron 877 has a neutral database position, but no measured benchmark evidence is present in the fact pack. The only numerical signals are the 0 aggregate score and the 50th percentile placement. Without benchmark records or rival deltas, the performance section of this database entry cannot support a score-based verdict.
