Intel Core i3-13100T vs Intel Core i5-11400T Comparison

Intel Core i5-11400T and Intel Core i3-13100T are both 35W TDP desktop processors, but they represent different generations and design philosophies. The i5-11400T is a 6-core, 12-thread Rocket Lake part from the 11th Gen, while the i3-13100T is a 4-core, 8-thread Raptor Lake part from the 13th Gen. The benchmark data shows a clear split: the older i5 wins in nearly every multi-threaded and Cinebench test, while the newer i3 takes a decisive victory in Geekbench single-core performance. This matchup is about core count versus architectural efficiency, and the database results show where each approach pays off.

Where Each One Wins

The Intel Core i5-11400T is the multi-core workhorse in this comparison. It wins 7 of the 8 recorded head-to-head benchmarks, including every Cinebench test and both Geekbench tests except one. The largest victory comes in Geekbench multi-core, where the i5-11400T scores 5591 against the i3-13100T's 4993, a 12% advantage. This makes sense given the core count difference: the i5 packs 6 cores and 12 threads, while the i3 has 4 cores and 8 threads. For workloads that scale across cores, such as video rendering, code compilation, or running multiple applications simultaneously, the i5-11400T is the stronger choice. Its Cinebench R23 multi-core score of 11113 versus 10840 confirms this, even if the margin is smaller at 2.5%.

The Intel Core i3-13100T has one clear win: Geekbench single-core. It scores 1780 there, beating the i5-11400T's 1597 by 10.3%. This is a significant gap and highlights the architectural advantage of Raptor Lake over Rocket Lake in lightly-threaded tasks. Applications that rely on a single thread, such as older games, spreadsheet calculations, or everyday web browsing, will feel snappier on the i3-13100T. The i3 also has a higher boost clock of 4.20 GHz compared to the i5's 3.70 GHz, which helps explain this single-core supremacy. If your primary concern is responsiveness in single-threaded software, the i3-13100T is the better pick.

The overall average benchmark score tells a similar story: the i5-11400T sits at 3309, slightly ahead of the i3-13100T's 3198. Both CPUs land in similar broad percentiles, 54th and 53rd respectively, so neither is a league above the other in the total CPU landscape. The data suggests the i5 is the safer choice for mixed workloads, while the i3 is specialized for single-thread speed.

Architecture Differences

The two processors come from different generations and use different manufacturing processes. The i5-11400T is built on Intel's 14 nm process as part of the Rocket Lake architecture, while the i3-13100T uses the 10 nm process with the Raptor Lake architecture. This node difference is reflected in die size: the i5-11400T has a die size of 276 mm², while the i3-13100T is much smaller at 163 mm². The smaller die on a newer process generally means better power efficiency per transistor, though both chips share the same 35W TDP.

Core and thread counts differ significantly. The i5-11400T offers 6 cores and 12 threads, while the i3-13100T offers 4 cores and 8 threads. This gives the i5 a 50% core advantage and a 50% thread advantage, which directly drives its multi-core benchmark wins. Cache layouts also differ. Both have 80 KB of L1 cache per core and 12 MB of shared L3 cache, but the L2 cache is different: the i5-11400T has 512 KB per core, while the i3-13100T has 1.25 MB per core. The i3's larger L2 cache per core helps with single-threaded performance, as more data can be stored closer to the execution units.

Memory support is another differentiator. The i5-11400T supports only DDR4 memory, while the i3-13100T supports both DDR4 and DDR5. The i5 has a recorded memory bandwidth of 51.2 GB/s, while the i3's memory bandwidth is not listed in the data. Both use dual-channel memory buses. PCIe capabilities also differ: the i5-11400T uses Gen 4 with 20 CPU lanes, while the i3-13100T uses Gen 5 with 20 CPU lanes. This means the i3 offers a newer PCIe interface, which could matter for future expansion cards or storage devices. The integrated graphics are identical: both use UHD Graphics 730.

Socket compatibility is a major practical difference. The i5-11400T fits Intel Socket 1200, while the i3-13100T fits Intel Socket 1700. This means they are not interchangeable on the same motherboard, and the platform choice will dictate which CPU you can use. The i5 was released on 2021-03-15 and is marked as end-of-life, while the i3 was released on 2023-01-03 and is still active production. Neither CPU has an unlocked multiplier, so overclocking is not officially supported on either.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent, narrow lead for the i5-11400T across all versions. In Cinebench R15 multi-core, the i5 scores 1120 against the i3's 1092, a 2.6% win. In R15 single-core, the i5 leads 157 to 154, a 1.9% margin. Moving to R20, the i5 wins multi-core 4667 to 4552 and single-core 658 to 642, both with a 2.5% delta. Cinebench R23 follows the same pattern: multi-core goes to the i5 with 11113 versus 10840, and single-core goes to the i5 with 1569 versus 1530, both again at 2.5%. These results show that despite the i3's architectural advantages, the i5's extra cores and threads keep it ahead in Cinebench's mixed workload, and even in single-core tests the i5 manages to edge out the i3.

Geekbench tells a different story. The multi-core test goes decisively to the i5-11400T with 5591 versus 4993, a 12% margin, which is the largest delta in any recorded benchmark. This reflects the i5's 6-core advantage in a test that scales well with core count. However, Geekbench single-core is where the i3-13100T strikes back. The i3 scores 1780, beating the i5's 1597 by 10.3%. This is the only benchmark where the i3 wins, but it is a substantial one, showing that Raptor Lake's newer IPC and higher boost clock give it a real edge when only one core is active. The overall win count stands at 7 for the i5 and 1 for the i3.

The Verdict

The data points to a simple conclusion: choose the Intel Core i5-11400T if your workloads are multi-threaded or mixed. It wins 7 of 8 benchmarks, including all Cinebench tests and Geekbench multi-core, and its 6 cores and 12 threads provide a solid foundation for rendering, compiling, or multitasking. Its average benchmark score of 3309 is higher than the i3's 3198, and it sits at the 54th percentile versus the i3's 53rd, so it is marginally stronger overall in the database's aggregate metrics. The i5 also carries a higher launch MSRP of $182, which reflects its higher core count.

Choose the Intel Core i3-13100T if single-threaded performance is your priority. Its Geekbench single-core score of 1780 is 10.3% ahead of the i5, and its higher boost clock of 4.20 GHz makes it more responsive in lightly-threaded applications. It also offers newer platform features, such as DDR5 memory support and PCIe Gen 5, which the i5 lacks. The i3 is the more modern part, still active in production, with a launch MSRP of $134. However, its 4 cores and 8 threads mean it falls behind in multi-core tests, and its overall average score is lower. For most builders who need balanced performance, the i5-11400T is the safer bet; for those who only care about single-thread speed and platform modernity, the i3-13100T is the data-backed pick.
