Intel Core i5-2450P

The Intel Core i5-2450P is a desktop processor from Intel’s Sandy Bridge generation, built on a 32 nm process with 1,160 million transistors on a 216 mm² die. It offers 4 cores and 4 threads, with a base clock of 3.20 GHz and a boost clock of 3.50 GHz. Its benchmark profile places it in the 30th percentile of all CPUs tracked, with an average benchmark score of 1086. The processor sits in a tight cluster of rivals, where score differences are measured in fractions of a percent, indicating that its performance class is defined more by consistency than by any single standout metric.

How It Compares

The nearest rival, the Intel Pentium 6805, posts an average score of 1087, which is just 0.1% higher than the i5-2450P’s 1086. This delta is within noise, meaning the two processors are effectively interchangeable in overall benchmark terms. However, the i5-2450P brings four physical cores, while the Pentium 6805 is a lower-tier part; the data shows that despite architectural differences, their aggregate performance lands in the same neighborhood.

The Intel Core i5-3475S averages 1085, a 0.1% deficit relative to the i5-2450P. This rival is a lower-power variant with a similar core count, and the delta is negligible. The i5-2450P holds a razor-thin edge, but the practical difference in real-world tasks would be imperceptible. The i5-3475S’s inclusion in this cluster suggests that power efficiency does not drastically alter average scores at this performance level.

The Intel Core i5-3450S also appears, with an average score of 1088, which is 0.2% above the i5-2450P. This is the largest delta among the listed rivals, yet it remains trivial. The i5-3450S is another Sandy Bridge-era part, and the data indicates that minor clock and cache variations among these models produce no meaningful separation in aggregate benchmarks.

Finally, the AMD Athlon 220GE matches the i5-3450S at 1088, also 0.2% ahead of the i5-2450P. This rival represents a different architecture and platform, yet its average score aligns closely. The data implies that for general-purpose computing, the i5-2450P is competitive with both Intel’s own lower-tier and AMD’s budget offerings, with all four rivals within a 0.3% band.

Power and Thermals

The i5-2450P carries a TDP of 95 watts. This places it in a conventional desktop power class for its era, requiring a cooling solution capable of handling sustained loads. The 95 W figure suggests a standard tower-style air cooler is sufficient; liquid cooling or oversized heatsinks are unnecessary for this processor. The absence of integrated graphics in the FACT PACK means the TDP is entirely attributable to the CPU cores, not to an iGPU component. In thermally constrained systems, the 95 W TDP implies that case airflow and cooler mounting are more critical than for lower-TDP parts, but it does not push into the territory of high-end enthusiast cooling. The data does not provide temperature or power draw measurements, so conclusions about thermals must be inferred from the TDP class alone.

Benchmark Performance

In Cinebench R15, the i5-2450P scores 366 in multi-core and 51 in single-core. The multi-core result is roughly 7 times the single-core score, which reflects the parallel scaling across four threads. Cinebench R20 shows 1525 multi-core and 215 single-core, a ratio of about 7.1. Cinebench R23 yields 3632 multi-core and 512 single-core, with a ratio of about 7.1. These consistent ratios indicate that the processor scales nearly linearly with core count, as expected for a 4-core/4-thread part without hyper-threading.

Geekbench results are lower in absolute terms: 1796 multi-core and 590 single-core, giving a ratio of about 3.0. This lower ratio suggests that Geekbench’s workload mix does not benefit as much from multi-threading as Cinebench’s render tasks do. The discrepancy between Cinebench and Geekbench ratios highlights that the i5-2450P’s multi-thread advantage is workload-dependent.

Relative to rivals, the i5-2450P’s average score of 1086 is 0.1% below the Pentium 6805 (1087) and 0.2% below the i5-3450S (1088) and Athlon 220GE (1088). It is 0.1% above the i5-3475S (1085). These deltas are all under half a percent, meaning that in aggregate benchmarks, the i5-2450P neither leads nor trails its immediate competition in any meaningful way. The percentile rank of 30 indicates that it outperforms roughly 30% of all CPUs in the database, placing it in the lower-middle tier overall.

Who Should Consider It

The benchmark data suggests the i5-2450P suits workloads that are lightly threaded but benefit from four physical cores. For office productivity—spreadsheets, word processing, web browsing with multiple tabs—the Geekbench single-core score of 590 is modest, but the four cores handle concurrent background tasks without stalling. The Cinebench R23 multi-core score of 3632 indicates that short rendering tasks or batch photo processing are feasible, though not fast by modern standards. For gaming, the single-core performance is the limiting factor; games that rely on high per-thread performance will see the i5-2450P lag behind newer parts, but older or less CPU-intensive titles remain playable. Content creation involving heavy multi-threaded video encoding would strain the 4-thread limit, as the R15 multi-core score of 366 is low compared to processors with more threads. The data points to a CPU for budget-conscious builds focusing on general use, light productivity, and legacy gaming, rather than for professional rendering or competitive esports at high frame rates.

Platform and Compatibility

The i5-2450P uses Intel Socket 1155, which was common for Sandy Bridge and Ivy Bridge desktop processors. It supports DDR3 memory in a dual-channel configuration, with no ECC support, targeting consumer motherboards. PCIe connectivity is Gen 3 with 16 lanes from the CPU, which is adequate for a single discrete graphics card; multi-GPU setups would be constrained by lane allocation. The processor does not include integrated graphics, so a dedicated GPU is mandatory for display output. The Sandy Bridge architecture uses a 32 nm process, and the socket’s compatibility extends to certain later chipsets, but the upgrade path from this platform is limited to other LGA 1155 processors. The lack of an unlocked multiplier means overclocking is restricted to bus speed adjustments, which were less flexible on this platform. The release date of January 29, 2012, places it early in the Sandy Bridge lifecycle, and the part number SR0G1 identifies this specific stepping. For users already on LGA 1155, the i5-2450P offers a drop-in replacement for dual-core Pentium or Celeron parts, but new builds would face outdated memory and PCIe standards.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread scores reveals a processor designed for parallel efficiency, but with modest per-core strength. In Cinebench R23, the single-core score of 512 is just 14% of the multi-core score of 3632, matching the theoretical 4x scaling from four cores. This linear scaling indicates the processor’s cores are balanced and the cache hierarchy (64 KB L1, 256 KB L2 per core, 6 MB shared L3) does not bottleneck multi-threaded workloads. However, the absolute single-core scores are low: Geekbench single-core at 590 and Cinebench R15 single-core at 51. These figures imply that tasks like spreadsheet recalculation, web rendering, or older game physics—which rely on one or two threads—will run at a pace typical of early-2010s hardware. Multi-threaded tasks that scale well, such as video transcoding or 3D rendering, benefit from the full 4-core utilization, but the 4-thread limit means they cannot exploit more parallelism. The data suggests that the i5-2450P is best suited for workloads that are explicitly multi-threaded, where its scaling is near-ideal, while single-thread-bound applications will feel dated. The 30th percentile ranking is dragged down by these weak single-thread results, as many modern CPUs achieve far higher per-core performance.
