Intel Core i5-1350P vs Intel Core i9-11900T Comparison

The Intel Core i5-1350P and Intel Core i9-11900T represent two distinct approaches to Intel processor design, separated by two generations and aimed at different market segments. The i5-1350P is a mobile-first Raptor Lake part, while the i9-11900T is a desktop Rocket Lake chip with a low-power TDP. Despite the i9’s higher tier and larger L3 cache, the benchmark data shows a consistent, narrow victory for the i5 across every Cinebench test, with deltas hovering around 6%. The i5-1350P’s average benchmark score of 4776 places it in the 59th percentile of all CPUs, while the i9-11900T’s 4685 average places it in the 58th percentile. This head-to-head analysis will break down where each processor wins, examine the architectural and specification differences, and detail the exact benchmark deltas.

FAQ

Q: Which processor has more cores and threads?

A: The Intel Core i5-1350P has 12 cores and 16 threads, while the Intel Core i9-11900T has 8 cores and 16 threads. The i5’s additional cores are a key factor in its multicore performance advantage.

Q: How do the two chips compare in single-core Cinebench R23 performance?

A: The i5-1350P scores 2331 in Cinebench R23 single-core, while the i9-11900T scores 2201. This gives the i5 a 5.9% lead in that specific test.

Q: What is the difference in their process nodes?

A: The i5-1350P is built on a 10 nm process, whereas the i9-11900T uses a 14 nm process. This node difference is a major architectural distinction between the two.

Q: Do both processors support the same memory types?

A: No. The i5-1350P supports both DDR4 and DDR5 memory, while the i9-11900T supports DDR4 only. The i9-11900T also has a listed memory bandwidth of 51.2 GB/s, a figure not provided for the i5.

Q: Which processor has a higher boost clock?

A: The i9-11900T has a higher boost clock at 4.90 GHz, compared to the i5-1350P’s 4.70 GHz. However, the i5 still wins all single-core benchmarks despite the lower clock.

Q: What are the launch MSRPs for these two processors?

A: The i5-1350P has a launch MSRP of $320, while the i9-11900T has a launch MSRP of $439. The i5 is the lower-priced part at launch.

Where Each One Wins

The data is unambiguous: the Intel Core i5-1350P wins all six head-to-head benchmark comparisons, leaving the Intel Core i9-11900T with zero wins. The i5’s victories are consistent across both single-core and multi-core workloads, with a uniform delta of 5.9% in four of the six tests. The only exception is Cinebench R20 single-core, where the i5 wins by a slightly larger 6% margin. This means the i5-1350P is the better performer in every Cinebench workload from R15 through R23, covering both rendering and single-threaded tasks.

For the i9-11900T, there is no benchmark category where it takes the lead. Its only available advantage lies in its specification sheet, not its measured performance. The i9 has a higher boost clock (4.90 GHz vs 4.70 GHz), a larger L3 cache (16 MB vs 12 MB), and a higher TDP (35 W vs 28 W), but these factors do not translate into any Cinebench win. The i5’s architecture and core count prove more decisive in practice, making it the winner in every measured workload.

Architecture Differences

The architectural gap between these two chips is substantial. The i5-1350P uses the Raptor Lake architecture, specifically the Raptor Lake-P variant, and is built on a 10 nm process node. In contrast, the i9-11900T uses the older Rocket Lake architecture on a 14 nm process. This node difference alone explains much of the performance parity despite the i9’s higher boost clock and larger cache, as the newer node allows for better efficiency and higher instructions per clock.

Core counts also differ significantly. The i5-1350P packs 12 cores and 16 threads, while the i9-11900T has 8 cores and 16 threads. The i5’s extra four physical cores provide a clear advantage in multi-threaded workloads, even though both have the same thread count. Cache layouts also diverge: the i5 has 2 MB of L2 cache per core, while the i9 has 512 KB per core. The i9’s L3 cache is larger at 16 MB shared, versus the i5’s 12 MB shared, but this does not overcome the i5’s core and process advantages.

The integrated graphics differ as well. The i5-1350P features Iris Xe Graphics with 80 execution units, whereas the i9-11900T includes UHD Graphics 750. Both are desktop or mobile integrated solutions, but the i5’s Iris Xe is generally positioned as a more capable GPU. The i5 is also a mobile segment part on Intel BGA 1744, while the i9 is a desktop part on Intel Socket 1200.

Specification Differences

The specification tables reveal several key differences beyond the benchmarks. The i5-1350P has a base clock of 1900 MHz and a boost clock of 4.70 GHz, while the i9-11900T has a lower base clock of 1500 MHz but a higher boost clock of 4.90 GHz. TDP also differs: the i5 is rated at 28 W, making it more power-efficient on paper, while the i9 is rated at 35 W, despite being a desktop chip.

Memory support is another differentiator. The i5-1350P supports both DDR4 and DDR5, giving it future-proofing options, while the i9-11900T is limited to DDR4. The i9 does have a listed memory bandwidth of 51.2 GB/s, a figure not provided for the i5. PCIe support is identical, with both offering Gen 4 and 20 lanes (CPU only). The i9 has a larger die size at 276 mm², while the i5’s die size is not listed. The i5’s L2 cache is larger per core (2 MB vs 512 KB), but the i9’s L3 cache is larger overall (16 MB vs 12 MB).

Production status also differs: the i5-1350P is listed as Active, while the i9-11900T is End-of-life. The i5 was released on 2023-01-03, whereas the i9 was released earlier on 2021-03-15. The i5’s launch MSRP is $320, and the i9’s is $439. Both have locked multipliers and do not support ECC memory.

Head-to-Head Benchmarks

The head-to-head data shows a remarkably consistent pattern. In Cinebench R15 multicore, the i5-1350P scores 1664 against the i9-11900T’s 1572, a 5.9% win. The single-core R15 test follows the same 5.9% delta, with scores of 234 and 221, respectively. Moving to Cinebench R20, the i5 wins multicore with 6935 versus 6550 (5.9%) and single-core with 979 versus 924 (6.0%). The trend continues in Cinebench R23, where the i5 scores 16514 versus 15596 in multicore (5.9%) and 2331 versus 2201 in single-core (5.9%).

The consistency of the 5.9% delta across nearly every test suggests a uniform per-clock or per-core advantage for the i5-1350P. The i5’s higher core count explains the multicore wins, while its superior single-core score indicates that the 10 nm Raptor Lake architecture delivers better instructions per clock than the 14 nm Rocket Lake design, despite the i9’s higher boost clock. The i5 also holds an average benchmark score of 4776, compared to the i9’s 4685, a difference of about 2% in the i5’s favor, though the i9’s nearest rivals include the Intel Core i9-10900F with a 0.5% delta, indicating close competition around its score tier.

The Verdict

From the data alone, the Intel Core i5-1350P is the clear choice for anyone prioritizing Cinebench performance. It wins every single benchmark in the comparison, with a 5.9% to 6% advantage across the board. Its 12-core design and 10 nm process give it a decisive edge over the 8-core, 14 nm i9-11900T, even though the i9 has a higher boost clock and more L3 cache. The i5 also offers DDR5 support and a lower TDP, making it a more modern and efficient option.

The i9-11900T, however, is not without merit for specific users. It is a desktop part with a higher boost clock (4.90 GHz) and a larger L3 cache (16 MB), which may appeal to those who prefer a traditional socketed platform (Intel Socket 1200) over the i5’s mobile BGA 1744 package. The i9 also has a listed memory bandwidth of 51.2 GB/s, a figure the i5 lacks. But in terms of raw benchmark performance, the i9 loses all six comparisons and its percentile rank (58th) is one point lower than the i5’s (59th).

Ultimately, the i5-1350P is the better processor for anyone who values measured performance in Cinebench workloads, offering a consistent lead in both single-core and multi-core tests. The i9-11900T is an older, end-of-life desktop chip that, despite its higher boost clock and larger cache, cannot match the i5’s architectural efficiency. For new builds, the i5-1350P’s active production status and superior benchmark results make it the stronger pick, while the i9-11900T remains a viable option only for those specifically needing a Socket 1200 desktop part with a higher boost clock.
