Intel Core 5 315 vs Intel Core i7-14701E Comparison

Head-to-Head Benchmarks

The benchmark data records 17 head-to-head comparisons between the Intel Core 5 315 and the Intel Core i7-14701E, and the Core i7-14701E wins every single one of them. The widest margin appears in Passmark integer math, where the Core i7-14701E scores 81,325 against the Core 5 315's 31,690, a delta of -61% from the Core 5 315's perspective. That gap is more than double the next largest margin, which is Passmark physics at -51.5% (2,399 versus 1,163).

The Cinebench suite shows a remarkably consistent pattern. Across R15, R20, and R23, both single-core and multi-core tests, the delta sits at -41.5% or -41.6%. The Core i7-14701E posts 2,237 in Cinebench R15 multi-core versus 1,308 for the Core 5 315; in R20 multi-core it is 9,321 versus 5,452; and in R23 multi-core it is 22,195 versus 12,981. Single-core Cinebench scores follow the same shape: R15 at 315 versus 184, R20 at 1,315 versus 769, and R23 at 3,133 versus 1,832. The consistency of roughly 41.5% across all six Cinebench tests indicates a structural advantage in both frequency and core count rather than a workload-specific quirk.

The Passmark suite offers a broader spread of deltas. Data compression shows -48.3% (282,939 versus 146,143), random string sorting shows -39.8% (29,158 versus 17,551), and find prime numbers shows -36.4% (176 versus 112). Extended instructions are closer at -29.1% (18,528 versus 13,143), and data encryption is the narrowest of the multi-threaded tests at -25.2% (14,862 versus 11,119). Floating point math sits at -31.4% (61,873 versus 42,441). The single-thread Passmark tests are the closest overall: 4,305 versus 4,021, a delta of only -6.6%. That single-thread gap is less than one-seventh of the integer math gap, which suggests the Core 5 315's per-core performance is comparatively strong even though its overall throughput lags badly.

The aggregate data confirms the direction. The Core i7-14701E holds an average benchmark score of 33,206 against 18,188 for the Core 5 315, and its percentile versus all CPUs is 83 compared to 72 for the Core 5 315. The Core i7-14701E's nearest rivals include the AMD Ryzen 9 PRO 6950H at 33,201 (delta 0%), the AMD Ryzen 5 8645HS at 33,244 (-0.1%), and the AMD Ryzen 7 7745HX at 33,091 (0.3%). The Core 5 315's nearest rivals include the AMD EPYC 9274F at 18,189 (0%), the Intel Core i7-9700 at 18,180 (0%), and the Intel Core i7-1365U at 18,177 (0.1%). Both chips sit within a narrow band of comparable performers, but that band is roughly 45% higher for the Core i7-14701E.

Architecture Differences

The two processors come from different Intel product lines with different design goals. The Core 5 315 is built on the Wildcat Lake codename and uses a 3 nm process node, while the Core i7-14701E uses the Raptor Lake-R codename, part of the Core 14th Gen series, on a 10 nm process node. The process difference alone explains much of the power and efficiency gap: the Core 5 315 has a TDP of 15, while the Core i7-14701E has a TDP of 65.

The core configuration differs substantially. The Core 5 315 has 6 cores and 6 threads, meaning no hyperthreading, while the Core i7-14701E has 8 cores and 16 threads. That doubles the thread count while adding only two physical cores. The Core i7-14701E also runs at a higher base clock of 2.60 GHz versus 1.50 GHz, and a higher boost clock of 5.40 GHz versus 4.40 GHz. The combination of more cores, more threads, and higher clocks across the board drives the large multi-threaded margins.

Cache hierarchies are organized differently. The Core 5 315 has 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. The Core i7-14701E has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The L3 advantage for the Core i7-14701E is substantial, more than five times the shared cache. The per-core L2 allocation also favors the Core i7-14701E on a per-thread basis when considering its 16 threads.

Memory support and I/O are also divergent. The Core 5 315 supports DDR5 and LPDDR5X over a single-channel bus with 59.7 GB/s of bandwidth. The Core i7-14701E supports both DDR4 and DDR5 over a dual-channel bus; the database does not record a bandwidth figure for it. The Core 5 315 has PCIe Gen 4 with 6 CPU lanes, while the Core i7-14701E has PCIe Gen 5 with 16 CPU lanes. The Core i7-14701E also supports ECC memory, which the Core 5 315 does not.

Integrated graphics differ as well. The Core 5 315 carries Intel Xe3 Graphics with 2 Xe cores, while the Core i7-14701E carries UHD Graphics 770. The sockets are incompatible: the Core 5 315 uses Intel BGA 1516, a mobile package, while the Core i7-14701E uses Intel Socket 1700, a desktop package. The market segments reflect this: the Core 5 315 is classified as Mobile, the Core i7-14701E as Desktop. The Core i7-14701E also has a larger die at 257 mm², while the Core 5 315 has no recorded die size. Release dates differ by roughly two years, with the Core 5 315 dated 2026-04-15 and the Core i7-14701E dated 2024-06-30.

The Verdict

The recorded data presents a clear performance hierarchy. The Intel Core i7-14701E leads the Intel Core 5 315 in every benchmark category measured, from single-thread Passmark at -6.6% to integer math at -61%. The average benchmark score gap is 33,206 versus 18,188, and the percentile ranking gap is 83 versus 72. For any workload that depends on raw throughput, multi-threading, or sustained compute, the Core i7-14701E is the stronger part.

The Core 5 315 does have structural advantages. Its 15 W TDP versus 65 W, its 3 nm process versus 10 nm, and its mobile BGA socket versus desktop Socket 1700 all point to a low-power, thin-and-light design. Its single-thread Passmark score of 4,021 is within 6.6% of the Core i7-14701E's 4,305, which is a modest gap given the TDP difference. The Core 5 315 also uses the newer integrated graphics (Xe3 versus UHD 770), supports LPDDR5X memory, and carries a launch MSRP of $340. The Core i7-14701E has no recorded launch MSRP.

For a desktop system where power draw and physical size are not constraints, the Core i7-14701E is the clear choice based on benchmark evidence. For a mobile platform where battery life and cooling matter, the Core 5 315's much lower TDP and newer process node make it a viable alternative, but the performance penalty is severe in multi-threaded tests. The data does not support any scenario where the Core 5 315 outperforms the Core i7-14701E on compute metrics.

Where Each One Wins

The Intel Core i7-14701E wins every recorded benchmark, so the practical question is where the Core 5 315's narrower losses make it competitive enough for specific roles.

The Core 5 315 is closest in single-thread Passmark, at -6.6%. For light, latency-sensitive tasks that rely on one or two threads, such as basic office work or web browsing, the Core 5 315's per-core performance is nearly on par with the Core i7-14701E despite using far less power. Its 1.50 GHz base clock and 4.40 GHz boost clock, combined with 6 threads, are sufficient for such workloads. The 15 W TDP and mobile socket also make it the only one of the two that fits into a portable chassis.

The Core i7-14701E dominates in every throughput-oriented category. The Cinebench suite, which stresses sustained multi-core rendering, shows a consistent -41.5% gap. Passmark integer math shows the worst case at -61%, and Passmark physics is nearly as bad at -51.5%. Data compression at -48.3% and random string sorting at -39.8% further confirm that the Core i7-14701E's 8 cores, 16 threads, and 33 MB L3 cache are decisive for parallel workloads. Its 65 W TDP and desktop socket also allow for higher sustained clocks, as reflected in its 5.40 GHz boost.

Memory bandwidth and I/O favor the Core i7-14701E as well. It supports dual-channel DDR4 and DDR5, while the Core 5 315 is limited to single-channel DDR5 or LPDDR5X. The Core i7-14701E also offers PCIe Gen 5 with 16 lanes versus Gen 4 with 6 lanes, which matters for users connecting high-speed storage or discrete GPUs. The ECC memory support on the Core i7-14701E adds reliability for workstation or server-adjacent use cases.

The Core 5 315's advantages are purely in power efficiency and newer platform elements. Its 3 nm process and 15 W TDP are unmatched by the Core i7-14701E's 10 nm and 65 W. The integrated Xe3 Graphics with 2 Xe cores is a newer design than the UHD Graphics 770. For a fanless or low-power mobile device, the Core 5 315 is the appropriate part. For anything requiring compute performance, the Core i7-14701E is the only choice supported by the benchmark data.
