Intel Core i5-13400T vs Intel Core i5-14401E Comparison

The Intel Core i5-14401E and Intel Core i5-13400T are both 10nm Raptor Lake desktop chips on Socket 1700, but they target different ends of the power spectrum. The 14401E is a 65W part with 6 cores and 12 threads, while the 13400T is a 35W low-power part with 10 cores and 16 threads. Benchmark data shows the 14401E wins every single head-to-head test, but the 13400T counters with more cores, a lower TDP, and a wider PCIe lane allocation. The average benchmark scores are extremely close — 5253 for the 14401E versus 5210 for the 13400T — placing both at the 60th percentile of all CPUs.

FAQ

Q: Which CPU has more cores and threads?

A: The Intel Core i5-13400T has 10 cores and 16 threads, while the Intel Core i5-14401E has 6 cores and 12 threads. Despite this core deficit, the 14401E still wins all six head-to-head Cinebench tests.

Q: What is the TDP difference between the two?

A: The 13400T is rated at 35W TDP, while the 14401E is rated at 65W TDP. This makes the 13400T the more power-efficient option on paper, though benchmark scores suggest the 14401E extracts more performance per core.

Q: How do their boost clocks compare?

A: The 14401E boosts to 4.70 GHz, which is higher than the 13400T's 4.40 GHz boost clock. The 13400T has a base clock of 1300.00 MHz, while the 14401E has a base clock of 2.50 GHz.

Q: Do both CPUs support ECC memory?

A: No. The 14401E supports ECC memory, but the 13400T does not. This is a notable differentiator for workstation or server-oriented builds.

Q: Which CPU has a higher average benchmark score?

A: The 14401E has an average benchmark score of 5253, compared to 5210 for the 13400T. The delta is 0.8% in favor of the 14401E.

Q: What is the launch MSRP of the 13400T?

A: The 13400T had a launch MSRP of $221. The 14401E has no launch MSRP listed in the data.

Where Each One Wins

The 14401E wins decisively in raw compute throughput. In Cinebench R23 multi-core, it scores 18161 versus 17029 for the 13400T, a 6.6% margin. Single-core performance also favors the 14401E: 2564 versus 2404 in R23 single-core, also a 6.7% edge. Every Cinebench test — R15, R20, and R23, both multi-core and single-core — goes to the 14401E with a consistent 6.6% delta. If your workload is heavily threaded rendering or compilation, the 14401E is the clear pick.

The 13400T wins where efficiency and platform flexibility matter. Its 35W TDP is nearly half the 14401E's 65W rating, making it suitable for compact or passively cooled builds. It also offers 20 PCIe Gen 5 lanes (CPU only) versus 16 on the 14401E, which matters if you need more direct CPU-attached storage or expansion. The 13400T also has 4 more cores and 4 more threads, which could help in lightly threaded or highly parallel workloads that scale beyond 12 threads — though the benchmark data does not show this advantage materializing in Cinebench.

Architecture Differences

Both CPUs are built on Intel's 10nm process and share the Raptor Lake architecture, but they come from different refresh generations. The 14401E is from the Raptor Lake Refresh generation (Core 14th Gen), while the 13400T is from the original Raptor Lake generation (Core 13th Gen). Both have a die size of 215 mm² and are fabricated by Intel.

The core configurations differ significantly. The 14401E has 6 cores and 12 threads, while the 13400T has 10 cores and 16 threads. Both CPUs share identical cache hierarchies: 80 KB L1 per core, 1.25 MB L2 per core, and 20 MB shared L3. The 14401E's higher clock speeds — 4.70 GHz boost versus 4.40 GHz — compensate for its lower core count in threaded workloads.

ECC memory support is another architectural split. The 14401E supports ECC memory, while the 13400T does not. Both support DDR4 and DDR5 memory in dual-channel mode, and both feature UHD Graphics 730 integrated graphics. The 13400T offers more PCIe Gen 5 lanes (20 versus 16), which is a platform-level difference rather than a core architectural one.

The rest of the specifications are identical: both use Intel Socket 1700, 10nm process, 215 mm² die size, 80 KB L1 per core, 1.25 MB L2 per core, 20 MB shared L3, DDR4/DDR5 dual-channel memory support, UHD Graphics 730, and are locked (multiplier not unlocked). Both are active production parts for the desktop market.

Head-to-Head Benchmarks

The 14401E wins all six head-to-head benchmark tests with a nearly uniform margin. In Cinebench R15 multi-core, the 14401E scores 1830 against 1716 for the 13400T, a 6.6% lead. The single-core R15 result is 258 versus 242, again a 6.6% delta. Moving to R20, the 14401E posts 7627 multi-core and 1076 single-core, versus 7152 and 1009 for the 13400T — both 6.6% ahead.

Cinebench R23 shows the same pattern: 18161 multi-core versus 17029, a 6.6% win, and 2564 single-core versus 2404, a 6.7% win. The consistency of these margins is striking — every test lands within a 6.6% to 6.7% range. This suggests the 14401E's advantage comes from clock speed rather than architectural efficiency, since the core count difference does not produce a larger multi-core gap.

The 13400T has additional Geekbench scores in its benchmark list — 10227 multi-core and 1899 single-core — but the 14401E has no Geekbench results in the data. Head-to-head comparisons are limited to Cinebench, where the 14401E is unbeaten. The 13400T's average benchmark score of 5210 is dragged down by its Cinebench performance, while the 14401E's 5253 average reflects its consistent leads.

The Verdict

The data points to a clear performance hierarchy: the Intel Core i5-14401E is the faster CPU in every measured benchmark. If you prioritize raw compute — rendering, encoding, or heavy multitasking — the 14401E's 6.6% lead across Cinebench R15, R20, and R23 makes it the straightforward choice. Its higher boost clock of 4.70 GHz and lower core count but faster per-core performance are exactly what single-threaded and moderately threaded workloads need.

The 13400T is the pick for efficiency-focused builds. Its 35W TDP is the standout feature, enabling quieter cooling and lower operating costs. The extra 4 cores and 4 threads give it a theoretical advantage in highly parallel scenarios, though the benchmark data does not confirm this in Cinebench. The 20 PCIe Gen 5 lanes also provide more expansion headroom for storage or accelerators.

The 14401E also offers ECC memory support, which the 13400T lacks — a meaningful feature for data integrity in workstation tasks. Both CPUs sit at the 60th percentile of all CPUs, and their average scores are within 0.8% of each other, so neither is a dramatic outlier. The 13400T's launch MSRP of $221 provides a reference point, but the 14401E has no listed launch price.

For most users, the 14401E is the better buy based on benchmarks alone. It wins every test, supports ECC, and its 65W TDP is still manageable for standard desktop cooling. The 13400T makes sense only if you specifically need the lower power envelope or the extra PCIe lanes, and you are willing to accept a consistent 6.6% performance deficit in Cinebench workloads. The 13400T's 10-core configuration may also appeal to those who trust core count over benchmark scores for future scaling, but the present data favors the 14401E without exception.
