Intel Core 3 305 vs Intel Core i7-14700F Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive victory for the Intel Core i7-14700F across all 17 recorded comparisons, with zero wins for the Intel Core 3 305. The most dramatic gap appears in integer math, where the Core i7-14700F scores 155,808 against the Core 3 305's 32,295, a delta of -79.3%. This workload, which stresses arithmetic throughput, favors the desktop chip's massive core count advantage.

Data compression tells a similar story. The Core i7-14700F posts 505,885 in PassMark's compression test, while the Core 3 305 manages 146,857, putting the mobile part 71% behind. The gap narrows considerably in extended instructions, where the Core i7-14700F's 28,564 is only 52.6% ahead of the Core 3 305's 13,543, but the desktop part still wins by a wide margin.

Cinebench results follow a consistent pattern. In R23 multicore, the Core i7-14700F scores 35,122 versus 13,123 for the Core 3 305, a 62.6% difference. The single-core R23 test shows the Core i7-14700F at 4,958 versus 1,852, a 62.6% gap as well. Across R15, R20, and R23, both multicore and single-core deltas hover between 62.6% and 62.7%, indicating that the performance ratio holds steady regardless of the workload intensity.

The closest contest comes in PassMark single-thread performance. The Core i7-14700F scores 4,257, while the Core 3 305 scores 3,977, a delta of only -6.6%. This suggests that in lightly threaded tasks, the newer mobile architecture partially compensates for its lower boost clock and smaller cache. Yet even here, the desktop chip retains the advantage.

Random string sorting shows a 68.5% gap, with the Core i7-14700F at 55,918 and the Core 3 305 at 17,623. Floating-point math reveals a 60.5% difference (107,005 versus 42,284), and physics simulation shows a 49.8% gap (2,455 versus 1,233). The smallest margins outside single-thread tests appear in prime number finding, where the Core i7-14700F's 176 beats the Core 3 305's 115 by 34.7%.

Data encryption delivers a 63.4% delta (30,144 versus 11,019), and multithread performance mirrors the Cinebench pattern with a 62.6% gap (41,317 versus 15,439). Across the entire benchmark suite, the average benchmark score tells the broader story: the Core i7-14700F averages 53,620, while the Core 3 305 averages 18,302. In percentile terms, the Core i7-14700F ranks in the 91st percentile of all CPUs, while the Core 3 305 sits in the 72nd.

Architecture Differences

The two processors represent fundamentally different design approaches. The Intel Core 3 305 uses Wildcat Lake architecture built on a 3 nm process, while the Intel Core i7-14700F uses Raptor Lake architecture on a 10 nm process. This node difference explains why the Core 3 305 achieves competitive single-thread performance despite having far fewer resources.

Core counts diverge sharply. The Core 3 305 has 6 cores and 6 threads, all presumably performance-oriented. The Core i7-14700F has 20 cores and 28 threads, indicating a hybrid arrangement with both performance and efficiency cores. The extra threads come from hyper-threading on the performance cores, which the Core 3 305 lacks entirely.

Cache hierarchies reflect the different design philosophies. The Core 3 305 has 192 KB of L1 cache, 2.5 MB of L2, and 6 MB of shared L3. The Core i7-14700F has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The desktop chip's larger L3 pool gives it a substantial advantage in data reuse scenarios, particularly for multi-threaded workloads.

Memory support also differs. The Core 3 305 supports DDR5 and LPDDR5X over a single-channel memory bus with 59.7 GB/s bandwidth. The Core i7-14700F supports DDR4 and DDR5 over a dual-channel bus. ECC memory is supported on the Core i7-14700F but not on the Core 3 305.

PCIe capabilities favor the desktop part. The Core i7-14700F offers Gen 5 with 16 CPU lanes, while the Core 3 305 offers Gen 4 with 6 CPU lanes. This has implications for bandwidth-hungry peripherals and GPU connectivity.

The integrated graphics situation is inverted. The Core 3 305 includes Intel Xe3 Graphics with 1 Xe core, while the Core i7-14700F has no integrated graphics (the F suffix indicates this). Users of the Core i7-14700F must have a discrete GPU, whereas the Core 3 305 can run with display output from the iGPU.

Physical specifications differ substantially. The Core 3 305 uses Intel BGA 1516, a mobile socket, while the Core i7-14700F uses Intel Socket 1700 for desktop. The die size of the Core i7-14700F is 257 mm², while no die size is recorded for the Core 3 305.

The TDP difference is striking: 15 W for the Core 3 305 versus 65 W for the Core i7-14700F. This reflects the mobile versus desktop positioning. The Core 3 305 is designed for power-constrained laptops, while the Core i7-14700F targets desktop systems where cooling and power delivery are less restrictive.

The release dates show the Core 3 305 is newer, coming out in 2026 versus 2024 for the Core i7-14700F. The newer process node (3 nm versus 10 nm) allows the Core 3 305 to deliver competitive single-thread performance at a fraction of the power draw.

Where Each One Wins

The Intel Core i7-14700F wins in every measured benchmark, but the nature of its victories varies. For multi-threaded productivity workloads, the desktop chip's advantage is overwhelming. Cinebench R23 multicore shows a 62.6% lead, and PassMark multithread shows the same margin. Integer math, data compression, and random string sorting all show gaps between 68.5% and 79.3%, indicating that heavily parallel tasks see the largest benefit from the Core i7-14700F's 20 cores and 28 threads.

The Core i7-14700F also wins in memory-intensive scenarios. Its 33 MB of shared L3 cache, dual-channel memory bus, and support for both DDR4 and DDR5 give it flexibility that the Core 3 305 lacks. The desktop chip's PCIe Gen 5 with 16 lanes further separates it from the mobile part's Gen 4 with 6 lanes, making it the clear choice for systems with high-bandwidth GPUs or NVMe storage.

The Intel Core 3 305 does not win any benchmark, but its closest margins reveal where it remains competitive. In PassMark single-thread tests, the Core 3 305 trails by only 6.6%, which is notable given the Core i7-14700F's 5.40 GHz boost clock versus the Core 3 305's 4.30 GHz. The mobile chip's 3 nm process and Wildcat Lake architecture deliver strong per-clock performance, allowing it to nearly match the older, higher-clocked desktop part in lightly threaded tasks.

The Core 3 305 also shows relative strength in prime number finding, where its 115 points are only 34.7% behind the Core i7-14700F's 176. This is the second-smallest gap after single-thread performance. The extended instructions test shows a 52.6% gap, indicating that SIMD-heavy workloads see less differentiation than raw integer math.

For use-case analysis, the Core i7-14700F is the appropriate choice for rendering, compilation, data processing, and any workload that can scale across many threads. Its 91st percentile ranking places it among the top desktop processors in the database. The Core 3 305, with its 15 W TDP and integrated graphics, fits scenarios where power efficiency and portability take priority over raw throughput. Its 72nd percentile ranking reflects solid overall performance for a mobile part, but the benchmark data shows it cannot match the desktop chip's multi-core dominance.

The average benchmark scores summarize the hierarchy: 53,620 for the Core i7-14700F versus 18,302 for the Core 3 305. The nearest rivals confirm this positioning, with the Core i7-14700F competing against server and workstation parts like the Intel Xeon 6505P and AMD EPYC 7313P, while the Core 3 305 sits alongside entry-level desktop and mobile processors such as the Intel Core i3-14100 and AMD Ryzen 5 2600E.
