Intel Core i5-1345U vs Intel Core i7-10700F Comparison

The Verdict

The Intel Core i7-10700F and Intel Core i5-1345U sit at nearly identical overall performance levels, with the desktop chip holding a razor-thin 0.5% average benchmark lead over the mobile part. The data shows a clear split: the i7-10700F is the choice for sustained multi-threaded workloads, winning 12 of 17 head-to-head comparisons, while the i5-1345U offers superior single-thread responsiveness and markedly better efficiency metrics. Buyers needing maximum throughput for rendering, compression, or extended instruction workloads should select the i7-10700F. Users prioritizing portability, integrated graphics, and newer platform features will find the i5-1345U more appropriate, despite its lower multi-core ceiling. The i7-10700F's aggregate score of 19499 against the i5-1345U's 19411 places both in the 73rd percentile of all CPUs, indicating that neither part is a clear overall winner.

Architecture Differences

The two processors represent fundamentally different Intel design philosophies. The i7-10700F uses the Comet Lake architecture on a 14 nm process node, while the i5-1345U employs the newer Raptor Lake architecture on a 10 nm node. The desktop part is built for the Intel Socket 1200 platform and targets the Desktop market segment, whereas the mobile chip uses Intel BGA 1744 and belongs to the Mobile segment. The i7-10700F features 8 cores and 16 threads, while the i5-1345U offers 10 cores but only 12 threads — an unusual configuration that reflects its hybrid efficiency-oriented design. The i5-1345U integrates Iris Xe Graphics 80EU, while the i7-10700F has no integrated graphics at all. Cache hierarchies differ substantially: the i7-10700F provides 64 KB L1 and 256 KB L2 per core with 16 MB shared L3, while the i5-1345U provides 80 KB L1 per core, 1.25 MB L2 per core, and a smaller 12 MB shared L3. The mobile part supports both DDR4 and DDR5 memory, whereas the desktop chip is limited to DDR4. PCIe capabilities also diverge, with the i7-10700F offering Gen 3 with 16 lanes versus the i5-1345U's Gen 4 with 8 lanes.

Head-to-Head Benchmarks

The multi-core Cinebench results heavily favor the desktop processor. In Cinebench R23 multi-core, the i7-10700F scores 13689 against the i5-1345U's 7724, a commanding 77.2% advantage. The R20 multi-core test shows a 16.3% lead (5749 vs 4942), and R15 multi-core shows a smaller 5.2% edge (1379 vs 1311). The i7-10700F also dominates in PassMark extended instructions, posting 16389 versus 9178 — a 78.6% gap that highlights its superior SIMD throughput. Data compression follows suit: the i7-10700F scores 253358 against 164005, a 54.5% difference. Random string sorting shows a 67.4% lead (31625 vs 18888), and integer math goes to the i7-10700F by 18.4% (62579 vs 52847). Floating point math is closer, with the desktop chip ahead by 7.3% (38578 vs 35939), and PassMark multi-thread shows an 11.8% edge (16227 vs 14511).

The i5-1345U wins its five head-to-head matchups on different grounds. Its most decisive victory comes in PassMark data encryption, where it scores 10288 versus 5378, a 47.7% advantage that suggests hardware acceleration advantages in the newer architecture. Single-thread performance also favors the mobile chip: PassMark single-thread shows 3415 versus 2875, a 15.8% lead, and Cinebench R15 single-core shows 240 versus 194, a 19.2% margin. The i5-1345U also wins PassMark physics by a slim 1.8% (818 vs 803). Interestingly, Cinebench R20 single-core bucks this trend, with the i7-10700F ahead 811 to 697 (16.4%), and R23 single-core also goes to the desktop part (1932 vs 1724, a 12.1% gain). The two chips tie exactly in PassMark find prime numbers at 47 each.

Specification Differences

The i7-10700F and i5-1345U differ across nearly every core specification. Clock speeds present a notable contrast: the desktop chip has a 2.90 GHz base clock and 4.80 GHz boost, while the mobile part lists a 1600.00 MHz base (which by convention indicates a different measurement methodology) and a 4.70 GHz boost. Thermal design power differs by a factor of more than four — 65 W for the i7-10700F versus 15 W for the i5-1345U — which explains the mobile part's suitability for thin laptops. The i7-10700F offers 16 threads from 8 cores, while the i5-1345U provides 12 threads from 10 cores, reflecting its hybrid configuration. Memory bandwidth is specified only for the desktop chip at 46.9 GB/s; the mobile part's bandwidth is not listed. Neither processor supports ECC memory, and neither has an unlocked multiplier. Release dates are nearly three years apart: the i7-10700F launched on 2020-04-29, while the i5-1345U arrived on 2023-01-03. The i5-1345U has a launch MSRP of $309. The mobile chip's part number is SRMLZ, while the desktop part is SRH70.
