Intel Core i5-1250P vs Intel Core i5-1340P Comparison

The Intel Core i5-1340P and Intel Core i5-1250P are two 12-core mobile processors that appear nearly identical on paper. Both share the same core and thread counts, the same 28 W TDP, and the same Intel BGA 1744 socket. Yet the benchmark data reveals a consistent, albeit narrow, edge for the newer Raptor Lake part across every single test. The question is not whether the i5-1340P is faster, but whether the margins it posts justify a closer look at what changed under the hood.

Head-to-Head Benchmarks

The benchmark results are remarkably one-sided. Across all six Cinebench tests, the Intel Core i5-1340P wins outright, with zero victories for the i5-1250P. The largest margin appears in the Cinebench R15 multi-core test, where the i5-1340P scores 1584 against the i5-1250P’s 1573, a 0.7% advantage. That same 0.7% delta repeats in Cinebench R20 multi-core, with scores of 6600 versus 6556, and again in Cinebench R23 multi-core, where the i5-1340P posts 15716 compared to 15610.

The single-core results tell a similar story, though the gaps are slightly tighter. In Cinebench R15 single-core, the i5-1340P edges ahead with 223 points versus 222, a 0.5% lead. Cinebench R20 single-core shows 931 against 925, a 0.6% margin. The Cinebench R23 single-core test rounds out the sweep with 2218 versus 2203, again a 0.7% difference. The pattern is clear: the i5-1340P gains ground in both single-threaded and multi-threaded workloads, but the improvements are incremental rather than transformative.

Looking at the broader competitive landscape, both processors sit in the 58th percentile of all CPUs, and their average benchmark scores are extremely close: 4545 for the i5-1340P and 4515 for the i5-1250P. The i5-1340P’s nearest rival list includes the Intel Core i7-10700KF at 4547, which is essentially a dead heat. The i5-1250P, meanwhile, sits just 0.7% behind its newer sibling, with the Intel Core i7-12700TE at 4513 as its closest competitor. These numbers suggest that neither chip is a performance outlier; both are solidly mid-pack mobile processors.

Where Each One Wins

Given the sweep, the use-case split is straightforward. The i5-1340P wins across the board, but the margins are so small that the practical difference in everyday tasks will be negligible. The data shows the i5-1340P is better suited for anyone who wants the absolute highest Cinebench scores available from these two parts, whether that is in single-core responsiveness or multi-core rendering. It wins every benchmark, so there is no scenario where the i5-1250P is the faster choice based on this data.

The i5-1250P does not win any benchmark category, but that does not mean it is a poor performer. Its scores are close enough that in real-world use, the difference between 15716 and 15610 in Cinebench R23 multi-core would be imperceptible. The i5-1250P’s strength lies in being a nearly equivalent alternative, particularly if the slightly older platform is more readily available. For users who prioritize the specific benchmark numbers, the i5-1340P is the clear pick; for those who just need a capable 12-core mobile chip, the i5-1250P remains entirely viable.

The percentile rankings reinforce this: both CPUs land at exactly the 58th percentile of all CPUs, meaning they occupy the same performance tier. The 0.7% delta in average benchmark score is within the noise of typical benchmarking variance. The i5-1340P wins, but it wins by fractions of a percent, not by leaps.

Architecture Differences

The core difference between these two processors lies in their underlying architectures. The i5-1340P is built on Raptor Lake, specifically the Raptor Lake-P codename, while the i5-1250P uses Alder Lake, with the Alder Lake-P codename. Both are fabricated on Intel’s 10 nm process node, and both use the same Intel BGA 1744 socket, so the physical platform is unchanged. The i5-1250P has a documented die size of 217 mm², while the i5-1340P does not list a die size in the data.

The cache configurations reveal a notable difference. Both chips share the same 80 KB L1 cache per core and 12 MB of shared L3 cache, but the L2 cache differs: the i5-1340P has 2 MB per core, while the i5-1250P has 1.25 MB per core. This larger L2 cache on the Raptor Lake part could contribute to its slightly higher benchmark scores, particularly in workloads that benefit from faster access to frequently used data.

Clock speeds also differ. The i5-1340P has a base clock of 1900 MHz and a boost clock of 4.6 GHz, while the i5-1250P runs at a 1700 MHz base and a 4.4 GHz boost. The higher boost clock on the i5-1340P aligns with its single-core benchmark advantage, while the higher base clock helps in sustained multi-core loads. Both processors feature the Iris Xe Graphics 80EU integrated GPU, support DDR4 and DDR5 memory in dual-channel configuration, and offer Gen 4 PCIe with 20 lanes from the CPU. Neither supports ECC memory, and both are locked (multiplier unlocked: false).

The release dates differ by roughly eleven months: the i5-1250P launched on 2022-02-22, while the i5-1340P followed on 2023-01-03. The i5-1340P carries a launch MSRP of $353, while the i5-1250P has no listed launch MSRP in the data. Both remain in active production.

The Verdict

The data is unambiguous: the Intel Core i5-1340P is the faster processor in every benchmark recorded. It wins all six Cinebench tests, with margins ranging from 0.5% to 0.7%. The i5-1250P never takes a single win. For anyone choosing strictly on performance, the i5-1340P is the correct pick, particularly if the higher boost clock and larger L2 cache matter for their specific workload.

However, the magnitude of the i5-1340P’s victory is small. A 0.7% difference in multi-core scores is unlikely to be noticeable outside of synthetic benchmarks. The i5-1250P remains a perfectly capable processor that performs within the same percentile band and delivers nearly identical average scores. The decision may come down to availability, platform familiarity, or the fact that the i5-1340P carries a known launch MSRP of $353 while the i5-1250P’s pricing is not documented.

Users who need the absolute peak Cinebench performance from this pair should select the i5-1340P. Users who encounter the i5-1250P at a favorable price or in a pre-built system should not feel shortchanged; the data shows they are getting 99.3% of the i5-1340P’s multi-core performance in the R23 test. The i5-1340P is the winner, but it is a narrow victory.
