Intel Core i5-1340P vs Intel Core i9-11900T Comparison

Head-to-Head Benchmarks

The benchmark data shows a remarkably consistent picture: the Intel Core i5-1340P wins every single recorded head-to-head comparison against the Intel Core i9-11900T. Across six Cinebench tests, the mobile chip takes the top spot each time, though the margins are uniformly narrow, ranging from 0.8% to 0.9%. This is not a rout by any means, but the direction of the results is unmistakable.

In Cinebench R15 multi-core, the i5-1340P scores 1584 against 1572 for the i9-11900T, a delta of 0.8%. The single-core result in the same test shows 223 versus 221, a 0.9% edge. Moving to Cinebench R20, the multi-core result reads 6600 for the i5-1340P and 6550 for the i9-11900T, again a 0.8% gap. The single-core R20 score is 931 against 924, also 0.8%. Cinebench R23 follows the same script: 15716 versus 15596 in multi-core and 2218 versus 2201 in single-core, both with a 0.8% delta.

What stands out is the consistency of the margin. The i5-1340P does not have a single dominant workload category where it pulls far ahead; instead, it wins by a small but repeatable amount across every rendering scenario. The i9-11900T, for its part, never manages to flip a result, even in single-core tests where older architectures sometimes retain an edge. The data shows a 6-0 sweep for the i5-1340P in the recorded head-to-head suite.

The average benchmark scores tell a slightly different story. The i9-11900T posts an average benchmark score of 4685, while the i5-1340P lands at 4545. This puts the i9-11900T about 3% higher in the aggregate metric, a result that reflects a broader benchmark set than the six Cinebench tests. Both chips sit in the 58th percentile of all CPUs in the database, an identical ranking. The nearest rivals for the i9-11900T include the Intel Core i9-10900F at 4664 (0.5% delta), the Intel Core i9-10900E at 4708 (-0.5% delta), the Intel Core i9-9900KF at 4652 (0.7% delta), and the Intel Core i7-6950X at 4734 (-1% delta). For the i5-1340P, the closest competitors are the Intel Core i7-10700KF at 4547 (0% delta), the Intel Xeon E-2356G at 4548 (-0.1% delta), the AMD Ryzen Embedded V2748 at 4532 (0.3% delta), and the Intel Core i5-1250P at 4515 (0.7% delta). The i9-11900T sits among older high-core desktop parts, while the i5-1340P aligns with a mix of desktop and embedded processors.

Architecture Differences

The two processors come from different Intel design eras and target different physical envelopes. The i9-11900T is built on Rocket Lake, a 14 nm desktop architecture with a 276 mm² die size, while the i5-1340P uses Raptor Lake-P, a 10 nm mobile design with no listed die size. The process node difference is significant: 14 nm versus 10 nm, which explains some of the efficiency characteristics reflected in the power envelopes.

Core counts differ sharply. The i9-11900T has 8 cores and 16 threads, all of them full-size performance cores. The i5-1340P has 12 cores and 16 threads, indicating a hybrid arrangement where some cores handle lighter workloads. Both parts present 16 threads to the operating system, but the i5-1340P reaches that thread count with more physical cores. The cache layouts also diverge. Both chips use an 80 KB L1 per core, but the L2 cache jumps from 512 KB per core on the i9-11900T to 2 MB per core on the i5-1340P. The i9-11900T counters with a larger shared L3: 16 MB versus 12 MB on the i5-1340P.

Clock speeds favor the desktop part. The i9-11900T has a base clock of 1500 MHz and a boost clock of 4.90 GHz. The i5-1340P starts higher at 1900 MHz base but tops out at 4.60 GHz boost. The i9-11900T therefore has a 300 MHz advantage in maximum boost, though the i5-1340P holds a 400 MHz lead at base frequency. The thermal design power ratings reflect their different roles: 35 W for the i9-11900T and 28 W for the i5-1340P, meaning the mobile chip delivers its benchmark results within a lower power envelope.

Memory support diverges as well. The i9-11900T supports DDR4 only, with dual-channel access and a listed memory bandwidth of 51.2 GB/s. The i5-1340P supports both DDR4 and DDR5, also dual-channel, though no bandwidth figure is recorded. Neither chip supports ECC memory. Both use PCIe Gen 4 with 20 lanes from the CPU. The integrated graphics differ: the i9-11900T ships with UHD Graphics 750, while the i5-1340P includes Iris Xe Graphics 80EU. The i9-11900T uses the Intel Socket 1200 platform, while the i5-1340P is soldered to BGA 1744, a mobile socket. Neither processor has an unlocked multiplier.

The Verdict

The i5-1340P is the clear winner in the recorded Cinebench suite, taking all six head-to-head tests. The margins are small, between 0.8% and 0.9%, but they are consistent across both single-core and multi-core workloads. For users who prioritize Cinebench rendering performance, the data points squarely to the i5-1340P.

That said, the i9-11900T has its own case. Its average benchmark score of 4685 exceeds the i5-1340P's 4545 by roughly 3%, and it does so while drawing 35 W versus 28 W. The i9-11900T also reaches a higher boost clock at 4.90 GHz, and it carries more shared L3 cache at 16 MB. The desktop platform with Socket 1200 offers upgrade and cooling flexibility that a soldered mobile chip cannot match.

The i5-1340P counters with a newer 10 nm process, more physical cores, a substantially larger L2 cache, and support for both DDR4 and DDR5 memory. It is also an active production part, while the i9-11900T is end-of-life. The i5-1340P launched in January 2023, nearly two years after the i9-11900T's March 2021 release. For a mobile platform, the i5-1340P delivers comparable or better Cinebench results within a lower power budget.

The choice depends on platform. The i9-11900T suits a desktop build where Socket 1200 boards, DDR4 memory, and a 35 W power envelope are acceptable, and where the higher average benchmark score matters. The i5-1340P suits a mobile or compact system where the 28 W envelope, 10 nm efficiency, and multi-core Cinebench superiority take priority. The data does not declare an absolute winner; it declares a workload and platform split. On raw Cinebench performance, the i5-1340P edges ahead. On aggregate performance across the broader database, the i9-11900T leads.
