About Intel Celeron 667
The Intel Celeron 667 is a desktop processor in the Celeron (Timna) generation, built on the P6 architecture at Intel's 180 nm process. The die size is 129 mm², and the part number is QV18. It has one core and one thread, with a base clock of 667.00 MHz and no boost clock. The package uses Intel Socket 370S, and the integrated graphics block is the Intel i752. The memory bus is single-channel, and memory support is listed as unknown because it depends on the motherboard. ECC memory is not supported, and the production status is end-of-life.
Benchmark Performance
The database record for the Celeron 667 contains an empty benchmarks array, so no measured benchmark scores are available for this processor. The avgBenchmarkScore field is recorded as 0, which is consistent with the absence of benchmark entries. Because no measured scores exist, that 0 should be treated as an unpopulated field rather than a performance result. The percentileVsAllCpus field is 50, which places the processor at the median of all CPUs in the database. This percentile is the only aggregate performance indicator present in the record. The base clock is 667.00 MHz, and since boostClock is null, the operating frequency is fixed rather than adaptive. With one core and one thread, the processor provides a single logical execution path. The cache hierarchy comprises 32 KB of L1 cache and 128 KB of L2 cache, with no L3 cache listed. The memory bus is single-channel, but memory bandwidth is not listed, so the memory subsystem cannot be quantified. No nearestRivals entries exist in the record, meaning there are no rival names, scores, or deltaPct values to report. Without those fields, no percentage differences against specific processors can be derived. The only comparative context is the 50th-percentile position, an aggregate value with no supporting benchmark rows in this entry.
Who Should Consider It
The market segment is Desktop, so the Celeron 667 is positioned for desktop platforms rather than mobile or server systems. The production status is End-of-life, which limits practical use to existing Socket 370S systems. The integrated Intel i752 graphics provides display output without a separate graphics card, making the part usable for basic desktop builds. Since the processor has one core and one thread, workloads that scale across multiple threads will not gain additional hardware execution resources. With a fixed 667.00 MHz base clock and no boost clock, the performance ceiling for that single thread is fixed. Memory support is listed as unknown and depends on the motherboard, so memory configuration is a board-level decision. ECC memory is not supported, which rules out configurations that require ECC. The listed cache amounts, 32 KB of L1 and 128 KB of L2, define the working set capacity visible to the single core; no L3 cache is present in the record. PCIe information is not listed, so expansion interface capabilities are unspecified in the database. The empty benchmark array means no gaming, office, or content-creation score is recorded; recommendations must therefore rely on the listed processor structure rather than measured workloads. Users with a light, single-threaded desktop workload and a compatible motherboard are the most plausible audience for this part. The i752 graphics is included in the package, but no graphics benchmark data exists to support a gaming assessment. The record does not list a release date, so the production timeline is defined only by the End-of-life status. For content creation, the lack of additional cores and the absence of creation benchmark scores make a creation-focused recommendation unsupported by the data. For heavier multithreaded tasks, the single-thread, single-core design is the limiting factor.
How It Compares
The nearestRivals array in this record is empty. No rival processor names are listed, so a paragraph-by-paragraph comparison against specific competitors cannot be written. Because no rival entries exist, there are no deltaPct values to report. The only comparative value present is percentileVsAllCpus, which is 50. This places the Celeron 667 at the median of the database's CPU distribution. However, the empty benchmarks array means that percentile is not backed by measured score entries in this record. The avgBenchmarkScore of 0 reflects the lack of measured benchmark data rather than a tested performance level. Without rival IDs, this processor cannot be said to lead or trail another CPU by any percentage. No nearest rival data is present in the database for this part. Any relative performance statement would require information not contained in the record. Therefore, the comparison section is confined to the aggregate percentile field and the absence of specific rival deltas.

Power and Thermals
The Celeron 667 has a TDP of 30 W. This 30 W value is the only thermal design point in the record. The manufacturing data lists a 180 nm process node and a 129 mm² die size, while the transistor count is not listed. The socket is Intel Socket 370S, so any cooling hardware must physically match that socket. The multiplierUnlocked field is false, meaning the multiplier is not available for user overclocking. With no boost clock, the thermal specification corresponds to the 667.00 MHz base-clock operating point. The integrated Intel i752 graphics is contained in the package, but the record does not provide a separate graphics power number. A 30 W TDP implies a modest cooling tier, and no reference cooler is listed in the database. The single-thread, single-core design at 667.00 MHz sets the workload envelope covered by the 30 W thermal specification. The locked multiplier keeps the thermal profile anchored to the stock frequency. The record provides no additional thermal measurements, so the 30 W TDP remains the sole thermal metric for this processor.
