Intel Core i5-1345UE vs Intel Core i7-9750HF Comparison

The Intel Core i7-9750HF and the Intel Core i5-1345UE occupy opposite ends of the mobile computing spectrum, yet their benchmark scores place them in a surprisingly tight contest. The data shows the i5-1345UE wins every single head-to-head benchmark, but the margins are consistently narrow, hovering around 6.8 percent. The i7-9750HF is a six-core, 12-thread Coffee Lake-HR part from 2019 with a 45 W TDP, while the i5-1345UE is a ten-core, 12-thread Raptor Lake-U processor from 2023 with a 15 W TDP. The newer chip's efficiency and architectural advantages translate into a clean sweep, but the older chip's higher base clock and dedicated thermal headroom keep it competitive in absolute performance terms.

The Verdict

The benchmark data presents a clear, if modest, victory for the Intel Core i5-1345UE. It wins all six head-to-head tests, with a consistent deltaPct of -6.8 percent against the i7-9750HF across Cinebench R15, R20, and R23 in both single-core and multi-core workloads. This means the i5-1345UE delivers roughly 7 percent more performance in every measured scenario. For users prioritizing raw benchmark scores, the i5-1345UE is the superior choice, and it achieves this while operating at a 15 W TDP compared to the i7-9750HF’s 45 W TDP. The data does not show a single test where the i7-9750HF pulls ahead; its wins tally is zero.

The i7-9750HF is not without merit, however. Its average benchmark score of 2662 is only 1.4 percent lower than the i5-1345UE’s 2698 average. The i7-9750HF’s nearest rivals include the Intel Xeon E5-4650 v3 and the Intel Core i7-9700T, with deltaPct values of -0.1 and -0.2, respectively, indicating it sits in a well-populated performance tier. The i5-1345UE’s nearest rivals are the Intel Core i7-8700T and Intel Core i7-1185G7E, with deltaPct values of -0.1 and -0.2. Both chips land at the 50th percentile among all CPUs, meaning they are neither weak nor exceptional in the broader market context.

For a system builder, the choice hinges on platform and power constraints. The i5-1345UE is the better performer and is an active, current production part with a 2023 release date, making it suitable for new designs. The i7-9750HF is end-of-life, released in 2019, and its 45 W TDP suggests it belongs in a larger chassis with more substantial cooling. The i5-1345UE, with its integrated Iris Xe Graphics 80EU, also offers a built-in GPU, whereas the i7-9750HF has no integrated graphics in the data. If the workload is purely CPU-bound and the platform is already fixed to BGA 1440, the i7-9750HF is serviceable; otherwise, the i5-1345UE is the data-backed winner.

Architecture Differences

The two processors come from different Intel generations and use different process nodes. The i7-9750HF is built on the Coffee Lake architecture, specifically the Coffee Lake-HR codename, using a 14 nm process node from Intel. Its die size is 149 mm². The i5-1345UE is a Raptor Lake part, with the Raptor Lake-U codename, manufactured on a 10 nm process node. This process difference is a primary driver of the efficiency gap: the i5-1345UE’s 10 nm node allows for a 15 W TDP while still delivering higher performance than the i7-9750HF’s 45 W TDP on 14 nm.

Core and thread counts differ significantly. The i7-9750HF has 6 cores and 12 threads, while the i5-1345UE has 10 cores and 12 threads. This means the i5-1345UE has more physical cores but an equal number of threads, suggesting a hybrid or efficiency-oriented core arrangement. Cache configurations also differ per-core. The i7-9750HF has 64 KB of L1 per core and 256 KB of L2 per core, while the i5-1345UE has 80 KB of L1 per core and 1.25 MB of L2 per core. Both share 12 MB of L3 cache, making their total cache pools equal in size but differently distributed.

Memory support and I/O are notable divergences. The i7-9750HF supports DDR4 memory only, with a dual-channel bus and a measured memory bandwidth of 42.7 GB/s. The i5-1345UE supports both DDR4 and DDR5, also on a dual-channel bus, though its memory bandwidth is not listed. The i5-1345UE also features PCIe Gen 4 with 8 lanes (CPU only), while the i7-9750HF uses PCIe Gen 3. The i5-1345UE includes integrated Iris Xe Graphics 80EU; the i7-9750HF has no integrated graphics listed. The i5-1345UE is an active production part, while the i7-9750HF is end-of-life, and neither has a launch MSRP in the data.

Where Each One Wins

The i5-1345UE wins in every benchmark category measured, making it the outright leader in both single-core and multi-core performance. Its single-core advantage is consistent: 132 versus 123 in Cinebench R15, 553 versus 515 in Cinebench R20, and 1317 versus 1227 in Cinebench R23. These are the same 6.8 percent deltas seen in multi-core tests. The i5-1345UE’s higher boost clock of 4.60 GHz, compared to the i7-9750HF’s 4.50 GHz, likely contributes to this edge, though the base clock of the i7-9750HF is much higher at 2.60 GHz versus the i5-1345UE’s 1400.00 MHz.

Multi-core performance tells a similar story. The i5-1345UE scores 940 versus 876 in Cinebench R15, 3918 versus 3652 in Cinebench R20, and 9329 versus 8696 in Cinebench R23. The i5-1345UE’s 10 cores provide a structural advantage in threaded workloads, even though the thread count is identical at 12. The i7-9750HF has no wins in any test, so there is no workload category where the data shows it outperforming the i5-1345UE. The i7-9750HF’s only potential advantage lies in its higher base clock, which may sustain performance in short bursts, but no benchmark in the pack confirms this.

For users on a strict power budget, the i5-1345UE is the clear winner, offering higher performance at one-third the TDP. For users with a platform already designed around the i7-9750HF’s BGA 1440 socket, the i5-1345UE is not a drop-in replacement, as it uses BGA 1744. The i7-9750HF’s 45 W TDP also suggests it may sustain peak boost clocks longer under heavy load, but the data shows the i5-1345UE still wins all multi-core tests, so this theoretical advantage does not materialize in the benchmarks.

Head-to-Head Benchmarks

The head-to-head benchmark table is unambiguous: the i5-1345UE wins all six tests, and the i7-9750HF wins none. The largest absolute gap is in Cinebench R23 multi-core, where the i5-1345UE scores 9329 against the i7-9750HF’s 8696, a difference of 633 points. The smallest absolute gap is in Cinebench R15 single-core, where the i5-1345UE scores 132 against 123, a difference of just 9 points. In every test, the deltaPct is -6.8 or -6.9 percent, indicating a remarkably consistent performance advantage.

In multi-core workloads, the i5-1345UE’s lead is steady. Cinebench R15 multi-core shows 940 versus 876, Cinebench R20 multi-core shows 3918 versus 3652, and Cinebench R23 multi-core shows 9329 versus 8696. These results suggest the i5-1345UE’s 10-core configuration scales better in threaded rendering tasks than the i7-9750HF’s 6-core setup, despite both having 12 threads. Single-core tests follow the same pattern: R15 single-core is 132 versus 123, R20 single-core is 553 versus 515, and R23 single-core is 1317 versus 1227.

The consistency of the 6.8 percent delta across all tests is notable. It implies the performance gap is not workload-dependent but rather a uniform architectural advantage. The i5-1345UE’s newer 10 nm process and higher boost clock of 4.60 GHz appear to deliver a systematic improvement over the i7-9750HF’s 14 nm process and 4.50 GHz boost clock. The i7-9750HF’s higher base clock of 2.60 GHz does not translate into any benchmark win, suggesting that sustained boost behavior favors the i5-1345UE. The average benchmark scores reinforce this: the i5-1345UE averages 2698, while the i7-9750HF averages 2662, a difference of 36 points. Both sit at the 50th percentile, but the i5-1345UE is consistently the faster part.
