Intel Core i5-1345UE vs Intel Core i7-9700T Comparison

The Intel Core i5-1345UE is the clear benchmark winner in this comparison, taking 6 out of 6 head-to-head tests against the Intel Core i7-9700T. While the i7-9700T is an older desktop part with a higher base clock, the data shows the mobile i5-1345UE consistently outperforms it by approximately 10.7-10.8% across both single-core and multi-core Cinebench workloads. This is a notable result given that the i5-1345UE is a 15W mobile processor facing a 35W desktop chip.

Head-to-Head Benchmarks

The i5-1345UE wins every benchmark in the comparison, with margins that are remarkably consistent. In Cinebench R15 multi-core, the i5-1345UE scores 940 against the i7-9700T's 839, a delta of -10.7% (negative delta indicating the i7-9700T trails). The single-core R15 result follows the same pattern: 132 for the i5-1345UE versus 118 for the i7-9700T, again a -10.6% gap.

Moving to Cinebench R20, the margins tighten slightly but remain decisive. The i5-1345UE posts 3918 multi-core and 553 single-core, while the i7-9700T manages 3496 and 493 respectively. Both deltas sit at -10.8%, meaning the i7-9700T is just under 11% slower in each case. This consistency across test versions suggests a fundamental per-clock advantage for the newer architecture rather than a workload-specific quirk.

Cinebench R23 tells the same story. The i5-1345UE reaches 9329 multi-core and 1317 single-core, while the i7-9700T trails at 8325 and 1175. The -10.8% delta appears again for both metrics. The i7-9700T does have Geekbench results (5503 multi-core, 1392 single-core) that the i5-1345UE lacks in the head-to-head data, but this does not offset the Cinebench sweep. The average benchmark score reinforces the picture: the i5-1345UE sits at 2698 versus 2668 for the i7-9700T, a small but consistent overall edge.

The i7-9700T's closest rivals in the overall database include the Intel Core i5-9500F (deltaPct -0.1) and the Intel Xeon E5-4650 v3 (deltaPct 0.1), while the i5-1345UE's nearest competitors are the Intel Core i7-8700T (deltaPct -0.1) and the Intel Core i7-1185G7E (deltaPct -0.2). Both processors sit at the 50th percentile among all CPUs, meaning they occupy a similar middle-ground tier despite the i5-1345UE's per-test advantage.

Architecture Differences

The two processors come from different eras and design philosophies. The i7-9700T uses the Coffee Lake architecture on a 14nm process node, with a die size of 180.3 mm². It is a desktop part released in 2019, now marked as end-of-life. The i5-1345UE uses the newer Raptor Lake architecture (specifically Raptor Lake-U) on a 10nm process node, released in 2023 and still active in production.

Core counts differ substantially. The i7-9700T has 8 cores and 8 threads, while the i5-1345UE offers 10 cores and 12 threads. That extra thread count comes from a hybrid configuration typical of newer Intel mobile parts, though the fact pack does not specify performance versus efficiency core breakdowns. The i5-1345UE's base clock is 1.40 GHz, significantly lower than the i7-9700T's 2.00 GHz, but its boost clock of 4.60 GHz exceeds the i7-9700T's 4.30 GHz. This higher boost ceiling helps explain the single-core wins.

Cache layouts also differ. The i7-9700T has 64 KB of L1 per core, 256 KB of L2 per core, and 12 MB of shared L3. The i5-1345UE has 80 KB of L1 per core, 1.25 MB of L2 per core, and also 12 MB of shared L3. The larger per-core L2 on the i5-1345UE is a meaningful architectural advantage for workloads that reuse data locally.

Memory support and PCIe differ as well. The i7-9700T supports only DDR4 with dual-channel memory and a bandwidth of 42.7 GB/s. The i5-1345UE supports both DDR4 and DDR5, also dual-channel, though its bandwidth figure is not provided in the data. PCIe lanes differ: the i7-9700T offers Gen 3 with 16 lanes, while the i5-1345UE offers Gen 4 with 8 lanes. The i5-1345UE also ships with Iris Xe Graphics 80EU integrated graphics, a more capable iGPU than the UHD Graphics 630 found in the i7-9700T, though no gaming or graphics benchmarks are in the fact pack to quantify that difference.

A: No. In the head-to-head data, the i7-9700T wins 0 tests and the i5-1345UE wins all 6. The i7-9700T does have Geekbench scores (5503 multi-core, 1392 single-core) that are not matched against the i5-1345UE in the provided data, but those are not head-to-head comparisons.

Q: How do their average benchmark scores compare?

A: The i5-1345UE has an average benchmark score of 2698, while the i7-9700T averages 2668. Both sit at the 50th percentile among all CPUs, indicating they are statistically near the middle of the performance distribution.

Q: What are the core and thread counts?

A: The i7-9700T has 8 cores and 8 threads. The i5-1345UE has 10 cores and 12 threads. The i5-1345UE's higher thread count comes from its hybrid architecture, though the fact pack does not detail the exact core type split.

Q: How do the boost clocks compare?

A: The i5-1345UE boosts to 4.60 GHz, which is higher than the i7-9700T's 4.30 GHz. The i7-9700T has a higher base clock at 2.00 GHz versus 1.40 GHz, but the boost advantage favors the i5-1345UE.

The Verdict

The data is unambiguous: the Intel Core i5-1345UE is the faster processor in every measured benchmark. It wins all six Cinebench tests with a consistent ~10.8% margin, despite having a lower base clock and a dramatically lower TDP. The i5-1345UE's advantage comes from its newer architecture, higher boost clock, and greater core/thread count. For anyone choosing between these two based purely on benchmark performance, the i5-1345UE is the correct pick.

However, the i7-9700T is not without merit. It is a desktop part with a higher base clock and a larger PCIe lane allocation (16 lanes of Gen 3 versus 8 lanes of Gen 4). Its 35W TDP, while higher than the i5-1345UE's 15W, is still modest for a desktop chip. The i7-9700T also has a known launch MSRP of $323, while the i5-1345UE's pricing is not available. The i7-9700T's Geekbench scores (5503 multi-core, 1392 single-core) are respectable, but they are not directly compared against the i5-1345UE in the head-to-head data.

The percentile rankings are identical at 50%, and the average benchmark scores are close (2698 vs 2668), but the head-to-head results are decisive. The i5-1345UE is the better processor for raw performance in Cinebench-style workloads. The i7-9700T remains a viable option only if desktop socket compatibility, higher PCIe lane count, or the specific DDR4-only memory configuration are priorities — but those are use-case considerations, not performance advantages.

Where Each One Wins

The i5-1345UE wins every multi-core and single-core Cinebench test: R15, R20, and R23. This makes it the stronger choice for CPU-bound productivity tasks like video rendering, 3D modeling, and batch processing, where its 10 cores and 12 threads outperform the i7-9700T's 8 cores and 8 threads. Its higher boost clock of 4.60 GHz also gives it the edge in single-threaded responsiveness.

The i7-9700T's strengths lie outside the benchmark suite. It offers 16 PCIe Gen 3 lanes versus the i5-1345UE's 8 Gen 4 lanes, which could matter for systems with multiple expansion cards or high-bandwidth peripherals. Its 42.7 GB/s memory bandwidth is specified, whereas the i5-1345UE's is not. The i7-9700T also uses the standard desktop Socket 1151, making it compatible with existing desktop motherboards, whereas the i5-1345UE requires BGA 1744, a soldered mobile socket. For a desktop build with specific I/O requirements, the i7-9700T has practical advantages that benchmarks do not capture.

The i5-1345UE, by contrast, is designed for mobile systems with a 15W TDP, making it suitable for thin-and-light laptops where power efficiency is critical. Its support for both DDR4 and DDR5 memory offers flexibility in system design. The integrated Iris Xe Graphics 80EU is also a more modern iGPU solution than the UHD Graphics 630, though no graphics benchmarks are available to quantify the difference. In summary, the i5-1345UE wins on performance and efficiency, while the i7-9700T wins on desktop platform compatibility and I/O expandability.
