Intel Core 2 Extreme X9100

The Intel Core 2 Extreme X9100 is a mobile processor in Intel's Core 2 product family, with a 2-core, 2-thread configuration and a base clock of 3.07 GHz. The record classifies it under the Core 2 Extreme (Penryn XE) generation, built on Intel's 45 nm process with a die size of 107 mm². It carries 64 KB of L1 cache and 6 MB of L2 cache, while no L3 cache, boost clock, PCIe specification, or benchmark scores are present. The part is listed with a 44 TDP, an unlocked multiplier, Intel Socket P compatibility, and an end-of-life production status.

Benchmark Performance

Benchmark data for this record are effectively absent. The benchmark array contains no entries, and the average benchmark score field is 0. This is not a low score; it is an empty score. The percentileVsAllCpus field is 50, which would normally imply a midpoint placement in a ranked list of processors, but because there are no measured scores in the record, the percentile cannot be tied to any particular application, game, or synthetic test. The nearestRivals list is also empty, so there are no deltaPct values to compare against named competing processors. Any statement about being a certain percentage faster or slower than a rival is unsupported by the data. Consequently, the benchmark performance for the X9100 must be read as unavailable rather than weak.

Without scores, the only performance-relevant fields are structural: 2 cores, 2 threads, a 3.07 GHz base clock, 6 MB of L2 cache, and a dual-channel DDR2/DDR3 memory bus. Those fields describe capability, but not measured throughput. The percentile value of 50 might be an artifact of an empty record, or it might represent a real all-CPU ranking from a prior dataset. The FACT PACK does not clarify. Therefore, this analysis will not fabricate a benchmark result. The database cannot quantify how the X9100 behaves under load, and any workload conclusion must rest on the listed specifications rather than on measured performance.

How It Compares

Nearest rivals: none. The nearestRivals field is empty, so the database provides no named comparison points. This distinguishes the X9100 from records that include rival scores and exact percentage deltas. Without those entries, the only positional number available is the all-CPU percentile of 50. One can say the X9100 is listed at the 50th percentile of all CPUs in the database, but one cannot say how close or far it sits from any particular alternate processor.

Within its own generation, the "Extreme" label and the generation field "Core 2 Extreme (Penryn XE)" suggest a top-tier positioning within the Core 2 era. The 2-core/2-thread count, however, is not extreme by later standards. The comparison is qualitative because no rival specifications or scores appear in the record. The empty rival list could mean no close competitor was within the threshold used by the database, or it could be an artifact of incomplete benchmark data. The FACT PACK does not specify which.

Platform and Compatibility

The X9100 is assigned to Intel Socket P. It belongs to the Core 2 architecture with the codename Penryn XE, and the generation field is "Core 2 Extreme (Penryn XE)." The process node is 45 nm, and the foundry is Intel. The die size is 107 mm². The part number SLB48SLG8MSLGE7 is the only product identifier beyond the name. The record's release date is 2008, and the production status is end-of-life.

Memory support is listed as DDR2 and DDR3 depending on motherboard, over a dual-channel memory bus. The motherboard therefore determines the actual memory technology; the CPU record alone does not fix a memory type. ECC memory is not supported, since the ECC memory field is false. PCIe support is not specified in the record, so the expansion interface remains unknown from this data. Integrated graphics are described as "on certain motherboards (Chipset feature)," meaning graphics output may be supplied by the chipset or motherboard rather than by the processor die. No memory bandwidth figure is recorded, and no transistor count is listed.

Upgrade path: the end-of-life production status means this processor record is not a current production item. Any installation would rely on existing Socket P motherboards or platforms that support a Penryn XE generation mobile chip. No other socket is listed, so the compatibility boundary is Socket P. Because the memory support is listed as dependent on the motherboard, users cannot assume both DDR2 and DDR3 support exist on any given board; the board must provide the matching slots and chipset support.

Who Should Consider It

The data does not supply benchmark scores, so any recommendation must be based on specification fields only. A 2-core, 2-thread processor with a 3.07 GHz base clock suits workloads that rely on raw frequency rather than many concurrent threads. The 44 TDP and mobile segment suggest a laptop or compact mobile platform where the motherboard already uses Socket P.

Users who want to tune frequency manually may be interested because the multiplierUnlocked field is true. That distinguishes the X9100 from a fixed-multiplier part, though the record does not include measurements of how far the multiplier can be raised. For gaming, creation, or office work, the database currently has no score to cite. The absence of benchmark data means this record cannot be used to evaluate expected frame rates, render times, or productivity marks. Someone with a specific legacy mobile platform, a compatible motherboard, and a desire for an unlocked mobile Core 2 Extreme part is the primary candidate.

The cache configuration is also relevant: 6 MB of L2 is the only large cache listed, and no L3 cache is present. Workloads that repeatedly access a 6 MB working set could benefit from that cache, but the data does not quantify the benefit. The dual-channel memory bus is present, though the missing bandwidth figure prevents a stronger statement about memory-heavy workloads.

Power and Thermals

The TDP field is 44. That is the thermal design power anchor for this record. For a mobile processor, a 44 TDP is a moderate thermal envelope, but the record does not contain rival TDP values, so no class comparison is possible from this data. The 45 nm process node is the manufacturing detail most relevant to power density; a 107 mm² die spreads that heat over a specific area, but the record gives no thermal dissipation measurements.

Cooling implications: the thermal solution must be capable of handling a 44 TDP processor in a mobile chassis. The record does not specify a cooler size, fan curve, or cooling tier. One can infer that a passive cooler is unlikely to be sufficient for a sustained workload, but the FACT PACK does not explicitly state this. Because production status is end-of-life, the original thermal solution may no longer be manufactured; however, the data does not describe cooler availability.

Single-Thread vs Multi-Thread Behavior

The X9100 has 2 cores and 2 threads. This is a one-thread-per-core configuration; no simultaneous multithreading field exists. The operating system would see two logical processors. The base clock is 3.07 GHz. The boost clock field is null, so the database does not record any higher turbo frequency. Thus, the only frequency available for either single-threaded or multi-threaded execution is the 3.07 GHz base clock, unless a user adjusts the unlocked multiplier.

Cache: 64 KB of L1 and 6 MB of L2. No L3 is recorded. The dual-channel memory bus is listed but no bandwidth number is present. For a single-threaded workload, the relevant fields are the 3.07 GHz base clock, the unlocked multiplier, and the L2 cache size. For multi-threaded workloads, the 2-thread limit is the hard constraint: the chip cannot scale beyond two simultaneous threads. The dual-channel memory bus might help when both threads access memory, but the unspecified bandwidth prevents a quantitative statement.

Real workload split: applications with one or two active threads can use the full frequency and cache; applications designed for many threads would leave most of the platform underutilized because only 2 threads exist. The percentile value of 50, if taken at face value, places this behavior at the midpoint of the database population, but without scores, the split remains a structural analysis rather than a measured one.
