About Intel Pentium 4 506
The Intel Pentium 4 506 is a Socket 775 desktop processor from Intel's Prescott-generation NetBurst line, released on 2005-05-31 and listed as end-of-life. It has one core and one thread, a 2.66 GHz base clock with no boost clock, and a 90 nm Intel process implementation with 125 million transistors on a 109 mm² die. The database assigns no series to this part and places it at the 50th percentile of all CPUs, while its benchmark list remains empty.
Benchmark Performance
The benchmark array is empty. The average benchmark score is recorded as 0, which means there are no measured workload scores in the record. As a result, the database provides no absolute performance figures for the Pentium 4 506 and no exact percentage deltas against any competitor.
The comparative field that does exist is the percentile: 50. A 50th-percentile position is the median of the database population, indicating that half of all recorded CPUs are above this processor and half are below it. That is a useful placement because it excludes both a near-bottom and a near-top ranking. The nearestRivals list is empty, so no rival name, rival score, or deltaPct value is available. The benchmark conclusion is limited to a median standing, with no score-based evidence behind that placement.
How It Compares
The nearestRivals field contains no entries. There is therefore no named rival to compare against, and no pairwise score gap can be reported. The closest thing to a comparison is the 50th percentile, which puts the Pentium 4 506 in the middle of the recorded CPU distribution. Without rival identities, the record cannot say which specific parts sit immediately above or below it.
The 1-core/1-thread configuration is the other comparative signal. Any multi-core or multi-threaded competitor would be able to execute more than one thread at a time; this part cannot, because one thread is its total execution resource. No such competitor is listed in the nearestRivals data, so the comparison remains architectural rather than score-based.
Power and Thermals
The processor is rated at an 84 W TDP. That TDP defines the thermal output and therefore the cooling requirement: the platform needs to dissipate 84 W under load. The physical details behind that figure are the 90 nm process node, 125 million transistors, and 109 mm² die size.
There is no boost clock, so the 2.66 GHz base clock is also the maximum sustained frequency. The absence of a boost clock removes any extra thermal allowance for frequency boosting. The cache layout includes a 16 KB L1 and a 1 MB L2, with no L3, which means the 1 MB L2 is the primary cache resource for reused data. ECC memory is not supported, so the platform does not require ECC memory components. The implied cooling tier is a standard desktop cooler for an 84 W processor.
Who Should Consider It
The Pentium 4 506 fits workloads that do not parallelize across threads. Office productivity, legacy desktop applications, and older single-threaded software are the natural candidates, because the processor has exactly one core and one thread. The 2.66 GHz base clock sets the maximum frequency a single thread will receive, with no boost above that level. The 1 MB L2 gives single-threaded code a reasonably large working set, while the 16 KB L1 handles immediate data.
Users with a Socket 775 motherboard that supports DDR1, DDR2, or DDR3 can use this processor with any of those memory types on a dual-channel bus. That memory flexibility makes it a plausible drop-in for an existing board in that socket family. However, software that expects parallel execution will not gain any multi-thread scaling, because there is no second thread to schedule. The end-of-life production status also means this is not a forward-looking platform choice.
Integrated graphics are not guaranteed by the CPU. The record describes them as "On certain motherboards (Chipset feature)", so a user must verify whether the motherboard chipset provides display output. Builders who already own a compatible Socket 775 board, or who need a single-thread part for a defined legacy workload, are the audience the data points toward.
Single-Thread vs Multi-Thread Behavior
The core and thread counts are both 1. There is no operating-system-visible second thread, so there is no parallel execution capability within this processor. All behavior is single-thread behavior, and multi-threaded software will run as a single thread on this part.
The fixed 2.66 GHz base clock with no boost clock means the frequency does not rise for a single-threaded burst. A given thread runs at the same clock speed consistently. The cache hierarchy supports that thread with a 16 KB L1 and a 1 MB L2, with no L3. Workloads whose active data fits in 1 MB will have a better time reusing cached data, while workloads that exceed the L2 must go to system memory. For multi-threaded workloads, the record offers no additional cores or threads, so throughput is capped by what one thread can do at 2.66 GHz.
Platform and Compatibility
The Pentium 4 506 uses the Intel Socket 775 interface. Memory support includes DDR1, DDR2, and DDR3, on a dual-channel memory bus, which gives a Socket 775 platform flexibility across three memory generations. ECC memory is not supported, so the platform is aimed at non-ECC desktop memory. The PCIe support is Gen 2, which applies to add-in expansion such as graphics and storage controllers.
Integrated graphics are a chipset feature rather than a CPU feature, as recorded: "On certain motherboards (Chipset feature)". The multiplier is locked, with multiplierUnlocked set to false, so the processor does not support multiplier-based overclocking. The market segment is desktop, and the production status is end-of-life. The part number is SL8PL, and the release date is 2005-05-31. The database records no series, no nearest rivals, and no benchmark scores for this processor. An upgrade path on Socket 775 would require another Socket 775 part, but this record lists no compatible or successor processors.
