Intel Atom N450

The Intel Atom N450 is an end-of-life mobile processor from Intel. It belongs to the Atom architecture, with the codename Pineview and the generation label “Atom (Pineview)”; no series name is recorded in the database. The chip has one core, two threads, and a base clock of 1667.00 MHz, with no boost clock. It is rated at a TDP of 6 and uses the Intel BGA 559 socket. Intel manufactures the chip on a 45 nm process with 123 million transistors and a die size of 66 mm². The release date is 2009-12-20T17:00:00.000Z, and the part number is SLBMG. Memory support is DDR2, ECC is not supported, and the integrated graphics are listed as “On certain motherboards (Chipset feature)”. The database entry contains no benchmark samples and no nearest rivals; the average benchmark score is 0, and the percentile versus all CPUs is 50.

Benchmark Performance

Benchmark results are absent from this entry. The benchmarks array is empty, and the average benchmark score is 0. That 0 is not a tested score; it is the recorded value in a page with no samples. The only ranking number is percentileVsAllCpus, which is 50. A percentile of 50 places the Atom N450 at the median of the CPU database, but it does so without any measured benchmark to back the position. The nearestRivals array is also empty, so there are no rival scores and no deltaPct values to compare. No statement of the form “x percent faster than” can be made for any specific processor.

Without measured data, the performance picture is entirely spec-based. The entry lists one core, two threads, a 1667.00 MHz base clock, no boost clock, 56 KB of L1 cache per core, and 512 KB of L2 cache per core. No L3 cache is specified, so the cached working set is limited to the L1 and L2 levels. The 50th percentile is a database-wide ranking rather than a same-segment comparison; it is not filtered by mobile, Atom, or any other category. The empty benchmark array reinforces the point that the percentile is a placeholder position, not a measured performance claim. The specifications point to a low-frequency, lightweight execution profile, but the database does not quantify how that profile translates into application performance.

Single-Thread vs Multi-Thread Behavior

The N450 presents a single physical core with two threads. That two-thread count is the only parallel execution resource in the entry. Both threads operate on the same core, so a two-thread workload cannot draw on a second core. With no boost clock, the 1667.00 MHz base clock is the only frequency figure available for both single-thread and multi-thread workloads. A single-threaded process gets the full use of the one core and the full 512 KB L2 cache, since the L2 field is listed per core and there is exactly one core. Similarly, the L1 cache is 56 KB per core, making 56 KB the total L1 capacity. The absence of an L3 field means no additional level of cache is specified above the L2.

The multiplier is not unlocked, so there is no multiplier-based overclocking path. The 1667.00 MHz base clock is therefore the maximum sustained operating point in the data. For real workloads, the single-thread case is defined by that clock and by the 512 KB L2 cache. The multi-thread case depends on how well two logical threads can share the same physical core, its caches, and the same 1667.00 MHz frequency. The data does not include a boost clock, so neither workload type can expect a frequency increase beyond the listed base. This is a design where thread count and per-core cache are modest, and the database provides no second core for parallel execution.

Platform and Compatibility

The platform is built around the Intel BGA 559 socket. The market segment is Mobile, and the processor is end-of-life. Memory support is DDR2, ECC memory is false, and no memory bus or memory bandwidth figures are listed. PCIe support is not recorded in the database, so expansion interface information is unavailable. The integrated graphics entry reads “On certain motherboards (Chipset feature)”, meaning graphics availability depends on the motherboard rather than being a guaranteed part of the CPU. The processor uses Intel’s 45 nm manufacturing process, with 123 million transistors and a 66 mm² die size. The part number is SLBMG, and the release date is 2009-12-20T17:00:00.000Z. The multiplier is not unlocked, so user-controlled multiplier changes are not part of the feature set.

The architecture field is Atom, the codename is Pineview, and the generation is Atom (Pineview); the series field is not populated. With an end-of-life mobile BGA part, the upgrade path is tied to the original board platform. The data does not provide a socketed desktop upgrade route. The compatibility story is a fixed, low-power mobile platform with DDR2 memory support. The cache figures are expressed per core, and because the part has one core, the per-core L1 and L2 values also represent the total cache available to the system. The integrated graphics being a chipset feature means the complete platform includes a motherboard dependency, not just the processor itself.

How It Compares

The nearestRivals list is empty for this processor. There are no rival names, no rival benchmark scores, and no deltaPct values. The Atom N450 therefore cannot be placed against a specific competitor using a percentage difference. The only comparative field in the entry is percentileVsAllCpus, which is 50. That positions the part at the midpoint of all CPUs in the database, but the absence of nearest rivals means the percentile is not supported by head-to-head sample data. The empty benchmark array reinforces the same point: there are no measured values with which to separate the N450 from any other CPU.

The data supports a neutral comparison statement: the N450 is recorded at the 50th percentile, with no rival-specific deltas. No rival can be said to be faster or slower, because no rival entry is present. The 50th percentile is the sole ranking metric, and it represents a midpoint rather than a tested advantage. Without a nearestRivals block, the comparison section is defined by the absence of measured competitive data rather than by a table of scores.

Power and Thermals

The TDP is 6. That is a very low thermal envelope for a processor, and it aligns with the Mobile market segment. The entry does not list any other thermal figures, so the cooling tier must be inferred from the 6 TDP and the platform characteristics. The processor is made on a 45 nm process with 123 million transistors and a die size of 66 mm²; those physical figures define the power and thermal surface. There is no boost clock, so there is no additional turbo state above 1667.00 MHz that would raise thermal demand. The multiplier is not unlocked, so overclocking does not appear as a thermal variable in the data.

The production status is end-of-life, meaning the product is no longer in active production. For cooling, the 6 TDP rating implies a modest solution is sufficient. The database does not specify a cooler size or type, but the thermal class is low. The small die size and the low TDP are consistent with a lightweight mobile design, and the lack of a boost clock keeps the thermal envelope fixed at the base operating state. The 45 nm process, 123 million transistors, and 66 mm² die size are the recorded physical context for that thermal rating.
