Intel Core i5-14600 vs Intel Core i7-14700HX Comparison

Architecture Differences

The Intel Core i7-14700HX and Intel Core i5-14600 both belong to Intel's Core 14th Gen series and share the Raptor Lake architecture, but they are distinct silicon variants aimed at different platforms. The i7-14700HX uses the Raptor Lake-HX refresh codename and is built for mobile systems, while the i5-14600 uses the Raptor Lake-R codename and targets desktop builds. Both are fabricated on Intel's 10 nm process with a 257 mm² die size, and both come from Intel's own foundry.

The most significant architectural divergence is in core and thread counts. The i7-14700HX offers 20 cores and 28 threads, while the i5-14600 provides 14 cores and 20 threads. That difference of six cores and eight threads directly explains the i7's advantage in heavily parallel workloads. The cache hierarchy also differs: the i7 carries 33 MB of shared L3 cache, while the i5 carries 24 MB. Both share the same per-core L1 (80 KB) and L2 (2 MB) configuration.

Clock speeds favor the desktop part. The i5-14600 has a 2.70 GHz base clock and a 5.20 GHz boost clock, while the i7-14700HX runs at 2.10 GHz base and 5.50 GHz boost. The i7 has the higher maximum boost, but the i5 has a notably higher base frequency, which matters for sustained single-threaded performance in power-constrained scenarios.

Both processors support DDR4 and DDR5 memory in dual-channel configuration, and both support ECC memory. PCIe connectivity is identical: Gen 5 with 16 lanes from the CPU. Integrated graphics are also the same, UHD Graphics 770. The i7-14700HX has an unlocked multiplier, whereas the i5-14600 is locked. The i7 uses the Intel BGA 1964 socket, and the i5 uses Intel Socket 1700. The i7 is rated at 55 W TDP, while the i5 is rated at 65 W TDP, reflecting the mobile versus desktop design priorities.

Where Each One Wins

The i7-14700HX wins in scenarios that demand raw core count and parallel throughput. Its 20 cores and 28 threads, combined with 33 MB of L3 cache, give it a clear edge in multi-threaded integer math, floating-point math, encryption, and prime number finding. The recorded data shows it wins 11 of the 19 head-to-head benchmark comparisons, including all the PassMark computational workloads except physics.

The i5-14600 wins in single-threaded and lightly threaded tasks. Its higher base clock and desktop power envelope translate into superior single-core performance in Cinebench R15, R23, Geekbench, and PassMark single-thread tests. It also wins in physics simulation and Geekbench multicore, despite having fewer cores, which indicates that its per-core efficiency and clock speed can overcome the i7's core advantage in certain real-world workloads. The i5 wins 8 of the 19 comparisons.

For mobile users, the i7-14700HX is the clear choice for content creation, video encoding, compilation, and heavy multitasking. For desktop users who prioritize snappy single-threaded response, office work, and applications that scale poorly beyond a few cores, the i5-14600 holds the advantage.

Specification Differences

The two processors differ in several measurable specifications. Core count is 20 versus 14 in favor of the i7-14700HX. Thread count is 28 versus 20, again favoring the i7. Base clock is 2.10 GHz for the i7 and 2.70 GHz for the i5. Boost clock is 5.50 GHz for the i7 and 5.20 GHz for the i5. TDP is 55 W for the i7 and 65 W for the i5.

The L3 cache is 33 MB shared on the i7 and 24 MB shared on the i5. The socket is Intel BGA 1964 for the i7 and Intel Socket 1700 for the i5. The codenames differ: Raptor Lake-HX versus Raptor Lake-R. The i7 is part of the Core i7 generation with the Raptor Lake-HX Refresh, while the i5 is Core i5 with Raptor Lake Refresh. The multiplier is unlocked on the i7 and locked on the i5. The market segment is Mobile for the i7 and Desktop for the i5. Both share the same process node, foundry, die size, memory support, memory bus, ECC support, PCIe configuration, and integrated graphics. Both were released on the same date, and both are currently Active in production.

Head-to-Head Benchmarks

The largest win for the i7-14700HX comes in Cinebench R15 multicore, where it scores 3812 against the i5's 3070, a 24.2% advantage. That is a substantial gap and reflects the i7's core and thread advantage in older Cinebench versions that scale strongly with core count. In Cinebench R20 multicore, the i7's lead shrinks to 2.1% (13059 versus 12794), suggesting that R20's workload is less dependent on raw core count. The i7 also wins Cinebench R20 singlecore by 2% (1843 versus 1806), a narrow but real victory.

In PassMark workloads, the i7 leads decisively in integer math with 131296 versus 117078, a 12.1% margin. Floating-point math shows a 9.4% edge (93836 versus 85759). Data encryption is 4% ahead (26092 versus 25082). Prime number finding is 6.5% ahead (165 versus 155). Data compression is 0.9% ahead (438539 versus 434620). Extended instructions are 0.2% ahead (25718 versus 25674). Random string sorting is 1% ahead (48544 versus 48043). PassMark multithread shows a 2% lead (36566 versus 35848).

The i5-14600 counters with its biggest win in Cinebench R23 singlecore, scoring 4300 versus 2103, a massive 51.1% advantage. That result is striking and indicates that the i5's single-threaded performance in R23 far exceeds the mobile i7. Cinebench R23 multicore also goes to the i5, 30464 versus 24595, a 19.3% margin. Cinebench R15 singlecore favors the i5 by 31.6% (433 versus 296). Geekbench singlecore is 12.7% higher on the i5 (2424 versus 2116). Geekbench multicore is 2% higher on the i5 (14680 versus 14390). PassMark physics is 3.3% higher (2330 versus 2252). PassMark single-thread is 5.3% higher (4167 versus 3947).

The overall benchmark record shows the i7 winning 11 tests and the i5 winning 8. However, the magnitude of the i5's single-core wins is often larger than the i7's multi-core wins, which explains why the i5's average benchmark score of 44889 is close to the i7's 45953, a difference of roughly 2.4%. Both CPUs sit at the 89th percentile among all CPUs in the database.
