Intel Celeron 887

The Intel Celeron 887 is a mobile processor from Intel with a Sandy Bridge architecture and a generation label of Celeron (Sandy Bridge). It contains 2 cores and 2 threads, with a base clock of 1500.00 and no boost clock. The part is built on a 32 nm process at Intel's foundry, using 504 million transistors on a 131 mm² die. It uses the Intel BGA 1023 socket and carries integrated graphics listed as Intel HD (Sandy Bridge). Memory support is DDR3 on a dual-channel bus, and ECC memory is disabled. The release timestamp is 2012-08-31T17:00:00.000Z, and the part number is SR0VA.

Benchmark Performance

The benchmarks array in the data set is empty, and the avgBenchmarkScore field is 0. This indicates that no aggregate performance value was recorded for the Intel Celeron 887. A non-zero score would imply at least one benchmark run; the data set shows no runs. The nearestRivals array is also empty, so no rival names, rival scores, or deltaPct values are available for comparison. Exact percentage deltas cannot be calculated from this data. No statement such as “ahead by a percentage” or “behind by a percentage” is possible, because the data set provides no comparison set.

The only comparative field present is percentileVsAllCpus, which is 50. That value places the processor at the midpoint of the database’s all-CPU percentile field. However, because the average benchmark score is 0 and the benchmark list is empty, this percentile is not accompanied by an observed performance number. It is a positional marker in the database rather than a measured performance result.

An empty benchmark section is itself informative. The Celeron 887 has not been assigned a score in this database, which is different from a processor with a meaningful average score of 0. The empty benchmarks array supports the interpretation that no score was recorded, while the avgBenchmarkScore of 0 is the default value in the same record. The empty nearestRivals array reinforces this reading: there is no sorted list of nearby CPUs, no best-case or worst-case deltas, and no peer ranking within the data set.

Single-Thread vs Multi-Thread Behavior

The Intel Celeron 887 presents 2 threads across 2 physical cores. Because the core count and thread count are equal, the processor does not expose any logical threads beyond the physical cores. A single-threaded workload has access to one core, one 64 KB L1 cache, and one 256 KB L2 cache. The shared 2 MB L3 cache is available to both cores, so even a single-core workload can use the full shared L3. The only clock in the data is baseClock at 1500.00; boostClock is null. Therefore, the data set does not list a higher frequency that a lightly loaded core could reach. For single-thread latency-sensitive tasks, the ceiling in the data is exactly 1500.00.

When both threads are active, the processor can use both cores. The aggregate cache resources are two 64 KB L1 slices, two 256 KB L2 slices, and one shared 2 MB L3 slice. The dual-channel DDR3 memory bus is shared by both cores. Because the multiplierUnlocked field is false, the data does not offer an unlocked ratio for changing the clock. The result is a symmetric dual-core part with no additional thread context. Multi-thread scaling is therefore limited to two threads.

Workloads that can use both cores will engage both physical cores; workloads that require more than two threads will have to be scheduled across those same two hardware threads. The distinction between single-thread and multi-thread behavior is essentially the difference between one active core and two active cores, with the same 1500.00 base clock in both cases. The memory interface and cache layout also remain the same whether one core or both cores are active. The shared 2 MB L3 is the main resource that connects the two cores, while L1 and L2 are described as per-core allocations.

Power and Thermals

The TDP field for the Intel Celeron 887 is 17. This is a low thermal envelope, and the marketSegment field identifies the part as Mobile. Taken together, these fields place the processor in a low-power mobile cooling tier. The 32 nm process node, Intel foundry, 504 million transistor count, and 131 mm² die size are the physical characteristics behind that envelope. A 131 mm² die with 504 million transistors is a compact chip, and the integrated graphics block labeled Intel HD (Sandy Bridge) is part of the same package. The graphics logic is contained within the same 17 TDP budget according to the data set.

The absence of a boost clock also matters for thermals. Because boostClock is null, the data set does not list a higher-frequency state that would create additional transient thermal load. The only clock present is 1500.00, and the TDP is 17. Memory support is DDR3 over a dual-channel bus, with ECC disabled. The DDR3 memory interface does not have ECC enabled, which is a specification detail rather than a thermal factor. The data set provides no cooler size or thermal solution, so the only thermal anchor is the 17 TDP and the mobile market segment.

Cooling for this processor can be designed around a 17 TDP part, but the the benchmark database does not specify any particular cooling apparatus. No other TDP value is present in the data, and no separate high-power operating mode is listed. What the data does show is a low-power mobile processor with a modest clock, no boost clock, and integrated graphics sharing the same thermal envelope.

How It Compares

The nearestRivals array for the Intel Celeron 887 is empty. In the data set, this array would be the source of rival names, rival scores, and deltaPct values for direct comparison. None are present, so no rival-by-rival paragraphs can be constructed. The only cross-CPU metric is percentileVsAllCpus, which is 50. A percentile of 50 places the processor at the midpoint of the database’s all-CPU ranking. It is neither above nor below the middle in that field. However, because the benchmark score that would normally be associated with that percentile is not stored in the pack, the percentile cannot be connected to an observed score.

Without nearest rivals, comparison is limited to the processor’s own specifications. It is a 2-core, 2-thread mobile part with a 1500.00 base clock and no boost clock. It carries Intel HD (Sandy Bridge) integrated graphics, supports DDR3 dual-channel memory, and does not support ECC. The socket is Intel BGA 1023, the release timestamp is 2012-08-31T17:00:00.000Z, and the part number is SR0VA. These fields are the only comparative anchors in the data set.

FAQ

Q: How many cores and threads does the Intel Celeron 887 have?

A: It has 2 cores and 2 threads. Because the counts match, the processor does not expose more than one thread per core.

Q: Does the processor have a boost clock?

A: No. The boostClock field is null; the only clock value in the data is baseClock at 1500.00.

Q: What is the cache layout?

A: The data lists 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 2 MB of shared L3 cache.

Q: What memory support is documented?

A: The processor supports DDR3 memory on a dual-channel bus, and ECC memory is not enabled.

Q: What TDP and market segment are recorded?

A: The TDP is 17, and the market segment is Mobile.

Q: Is the multiplier unlocked?

A: No. The multiplierUnlocked field is false, so the data does not identify this part as unlocked.
