Intel Core i5-1335U vs Intel Core i7-10700F Comparison

Head-to-Head Benchmarks

The benchmark data reveals a clear split between the Intel Core i7-10700F and the Intel Core i5-1335U, with each processor dominating in different workloads. Out of 17 head-to-head comparisons, the i7-10700F claims 10 wins while the i5-1335U takes 7, but the margins tell a more nuanced story than the raw win count.

Starting with multi-threaded rendering, the i7-10700F posts a decisive victory in Cinebench R23 multicore with a score of 13689 against the i5-1335U's 8889.5, a 54% advantage. This pattern repeats in Cinebench R20 multicore, where the i7-10700F scores 5749 versus 4935, a 16.5% lead. The gap narrows in Cinebench R15 multicore, where the i5-1335U actually wins with 1464 points against 1379, a 5.8% edge. This reversal across Cinebench versions suggests that the older R15 test favors the mobile chip's architecture in ways that newer tests do not.

Single-core performance is similarly divided. The i5-1335U takes the PassMark single-thread test with 3336 points versus the i7-10700F's 2875, a 13.8% margin. It also wins Cinebench R15 singlecore with 238 versus 194, an 18.5% gap. However, the i7-10700F fights back in newer single-core tests: Cinebench R20 singlecore sees the i7-10700F at 811 versus 696, a 16.5% lead, and Cinebench R23 singlecore shows 1932 versus 1684.5, a 14.7% advantage.

The data compression test delivers one of the largest margins of the entire comparison. The i7-10700F scores 253358 in PassMark data compression, while the i5-1335U manages 159593, a 58.8% difference. Extended instruction throughput is even more lopsided: 16389 versus 8974, a 82.6% gap in favor of the desktop chip. Random string sorting also heavily favors the i7-10700F, with 31625 points against 17953, a 76.2% advantage.

Integer math performance shows the i7-10700F ahead by 22.1%, scoring 62579 versus 51244. Floating point math is closer, with the i7-10700F at 38578 against 35176, a 9.7% margin. The PassMark multithread score gives the i7-10700F a 13.6% edge at 16227 versus 14281.

Yet the i5-1335U has its own standout victories. Data encryption is a remarkable win for the mobile processor: it scores 10009 against 5378, a 46.3% advantage. This is the largest margin in the i5-1335U's favor and indicates a significant architectural advantage in cryptographic workloads. The i5-1335U also edges out the i7-10700F in PassMark physics (837 versus 803, a 4.1% margin) and in prime number finding (48 versus 47, a 2.1% margin).

Where Each One Wins

The i7-10700F is the clear choice for sustained multi-core rendering and compute-heavy desktop workloads. Its Cinebench R23 multicore score of 13689 places it far ahead of the i5-1335U, and the 54% delta in that test is the single largest multi-threaded gap in the dataset. The 82.6% lead in extended instructions and 76.2% lead in random string sorting reinforce this pattern: this is a processor built for heavy data manipulation and parallel execution. The 58.8% advantage in data compression further cements its position for archive handling and file system tasks. For integer math, the 22.1% lead means the i7-10700F handles algorithmic workloads with noticeably more headroom.

The i5-1335U excels in scenarios where single-thread responsiveness and encryption throughput matter more than raw core count. Its 13.8% lead in PassMark single-thread and 18.5% lead in Cinebench R15 singlecore indicate strong per-core performance for everyday applications. The 46.3% encryption advantage is particularly striking: the i5-1335U delivers nearly double the data encryption throughput, making it the better option for VPN traffic, disk encryption, and secure communication workloads. The physics test also favors the i5-1335U, suggesting an edge in certain simulation or gaming physics calculations.

The overall average benchmark scores place the two processors very close together: the i7-10700F averages 19499 while the i5-1335U averages 18982. Both sit at the 73rd percentile among all CPUs in the database. The i7-10700F's nearest rivals include the Intel Core i5-1345U (0.5% higher average), the AMD Ryzen 5 5500 (0.5% lower), and the AMD Ryzen AI 5 430 (0.6% lower). The i5-1335U's nearest rivals include the AMD EPYC 7773X (exactly equal), the Intel Core i5-12400F (0.3% higher), and the AMD Ryzen 5 7535HS (0.3% higher).

Architecture Differences

The architectural gap between these two processors is substantial. The i7-10700F uses Intel's Comet Lake architecture on a 14 nm process node, while the i5-1335U employs Raptor Lake on a 10 nm node. This process difference explains much of the efficiency and single-thread behavior observed in the benchmarks.

The core configurations are fundamentally different. The i7-10700F provides 8 cores and 16 threads, while the i5-1335U offers 10 cores but only 12 threads. The i5-1335U's hybrid design combines performance and efficiency cores, which is why it has more cores but fewer threads. Base clock speeds reflect their intended segments: the i7-10700F runs at 2.90 GHz with a 4.80 GHz boost, while the i5-1335U has a 1300.00 MHz base clock and 4.60 GHz boost. The i7-10700F carries a 65 W TDP, whereas the i5-1335U is rated at just 15 W, making it far more suitable for thin-and-light laptops.

Cache hierarchies also differ. The i7-10700F has 64 KB of L1 cache per core, 256 KB of L2 per core, and 16 MB of shared L3 cache. The i5-1335U has 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3. The i5-1335U's larger per-core L2 cache likely contributes to its single-thread wins in older Cinebench tests.

Memory support diverges significantly. The i7-10700F supports DDR4 only, with dual-channel memory and 46.9 GB/s bandwidth. The i5-1335U supports both DDR4 and DDR5, also dual-channel, though no bandwidth figure is recorded. The i7-10700F uses Intel Socket 1200 with PCIe Gen 3 and 16 CPU lanes, while the i5-1335U uses Intel BGA 1744 with PCIe Gen 4 and 8 CPU lanes. The i5-1335U also integrates Iris Xe Graphics with 80 execution units, whereas the i7-10700F has no integrated graphics.

The i7-10700F was released on 2020-04-29, while the i5-1335U launched on 2023-01-03. The i5-1335U has a launch MSRP of $340, while the i7-10700F has no recorded launch MSRP. Both processors remain in active production, and neither has an unlocked multiplier.

The Verdict

The data supports a clear division of purpose. The Intel Core i7-10700F is the superior choice for multi-threaded desktop workloads, sustained rendering, and data-heavy computation. Its 54% lead in Cinebench R23 multicore, 58.8% advantage in data compression, and 82.6% lead in extended instructions make it the stronger processor for content creation, scientific computing, and server-like tasks. The 16.5% wins in both Cinebench R20 multicore and singlecore show that its older Comet Lake architecture still delivers competitive performance in modern rendering tests.

The Intel Core i5-1335U is the better option for single-thread responsiveness, cryptographic workloads, and mobile efficiency. Its 13.8% lead in PassMark single-thread, 18.5% lead in Cinebench R15 singlecore, and 46.3% encryption advantage make it attractive for everyday productivity, secure communications, and battery-conscious devices. The 15 W TDP against the i7-10700F's 65 W TDP means the i5-1335U can operate in laptops without active cooling solutions, while the i7-10700F requires a desktop chassis with adequate thermal management.

The overall average benchmark scores are close, with the i7-10700F at 19499 and the i5-1335U at 18982, and both processors rank at the 73rd percentile. The i5-1335U also benefits from newer architecture, Raptor Lake on 10 nm versus Comet Lake on 14 nm, plus support for DDR5 memory and integrated Iris Xe Graphics. However, the i7-10700F compensates with more PCIe lanes (16 versus 8) and higher memory bandwidth at 46.9 GB/s.

Users who need maximum multi-threaded throughput and are building a desktop system should choose the i7-10700F. Users who prioritize single-thread speed, encryption performance, and portability should select the i5-1335U. The choice is not about which processor is universally better, but which workload profile matches the user's needs.
