Intel Core i7-4940MX vs Intel Xeon E-2314 Comparison

The Intel Xeon E-2314 and Intel Core i7-4940MX are both 4-core processors, but they come from different eras and target different segments. The Xeon E-2314 is a Rocket Lake-E server/workstation chip, while the i7-4940MX is a Haswell mobile extreme edition. In the recorded head-to-head benchmarks, the Xeon wins all six Cinebench tests, with deltas around 14.8%. This analysis walks through the architecture, specifications, and benchmark results to show where each processor stands.

The Verdict

The benchmark data is unambiguous. The Intel Xeon E-2314 wins every head-to-head comparison against the Intel Core i7-4940MX. Across the six Cinebench tests, the Xeon leads by 14.8% in five of them and by 14.7% in the remaining single-core R20 test. The i7-4940MX, despite having twice the thread count (8 threads versus 4), cannot overcome the architectural and clock advantages of the newer Xeon.

The Xeon E-2314 also holds a higher average benchmark score: 1911 versus 1886 for the i7-4940MX. Both processors sit at the 43rd percentile among all CPUs in the database, but the Xeon's average score is 25 points higher. The i7-4940MX is end-of-life, while the Xeon is active, so for any new build the Xeon is the clear choice. The i7-4940MX does have an unlocked multiplier and integrated graphics, but those features do not translate into compute performance in the recorded tests. For raw processing power, the Xeon E-2314 is the winner.

Architecture Differences

The two processors are built on different architectures and process nodes. The Xeon E-2314 uses Rocket Lake-E, a 14 nm design, while the i7-4940MX uses Haswell on a 22 nm process. The Xeon has a die size of 276 mm², while the i7 is smaller at 177 mm². The i7-4940MX lists 1,400 million transistors; the Xeon does not have a transistor count in the database.

Core and cache configurations differ as well. Both have 4 physical cores, but the i7-4940MX supports 8 threads through Hyper-Threading, while the Xeon is limited to 4 threads. The Xeon has larger per-core caches: 80 KB L1 and 512 KB L2, compared to 64 KB L1 and 256 KB L2 on the i7. Both share 8 MB of L3 cache.

Memory support is another major split. The Xeon uses DDR4 with dual-channel memory and a bandwidth of 51.2 GB/s, while the i7 uses DDR3 with dual-channel memory and a bandwidth of 25.6 GB/s. The Xeon also supports ECC memory, which the i7 does not. PCIe connectivity differs: the Xeon offers Gen 4 with 20 lanes, while the i7 offers Gen 3 with 16 lanes.

The i7-4940MX includes integrated graphics (Intel HD 4600), while the Xeon has none. The Xeon is a server/workstation part on Intel Socket 1200, while the i7 is a mobile part on Intel Socket G3. The Xeon has a TDP of 65 W, the i7 has 57 W. The Xeon's base clock is 2.80 GHz with a boost of 4.50 GHz; the i7's base is 3.10 GHz with a boost of 4.00 GHz. The Xeon's multiplier is locked, the i7's is unlocked. The Xeon was released on 2021-09-07, the i7 on 2014-01-19. The Xeon's launch MSRP is $182, the i7's is $1096.

Head-to-Head Benchmarks

The head-to-head results are consistent across all six Cinebench tests. The Intel Xeon E-2314 wins every test, with deltas of 14.8% in five tests and 14.7% in one. The largest absolute margin is in Cinebench R23 multi-core, where the Xeon scores 6609 against the i7's 5759, a difference of 850 points. In single-core R23, the Xeon scores 933 versus 813, a 120-point gap.

In Cinebench R20, the Xeon leads with 2775 multi-core and 391 single-core, while the i7 scores 2418 and 341 respectively. The R15 results follow the same pattern: 666 versus 580 multi-core, and 93 versus 81 single-core. The i7-4940MX has no wins in any recorded benchmark.

The average benchmark scores reinforce this picture. The Xeon E-2314 averages 1911, while the i7-4940MX averages 1886. Both sit at the 43rd percentile, but the Xeon's nearest rival is the Intel Xeon E3-1575M v5 with an average score of 1910 and a delta of 0%. The i7's nearest rival is the Intel Xeon D-1531 with an average score of 1885 and a delta of 0.1%. These close rivalries show that both processors are competitive within their own performance tier, but the Xeon is clearly ahead of the i7.

Where Each One Wins

The Intel Xeon E-2314 wins in every compute benchmark recorded. Its higher boost clock, larger caches, and newer architecture give it a decisive edge in both single-threaded and multi-threaded Cinebench workloads. The Xeon also supports ECC memory and PCIe Gen 4, making it suitable for server and workstation tasks that require reliability and modern I/O. Its active production status and lower launch MSRP further position it as the practical choice for new systems.

The Intel Core i7-4940MX does have some advantages, but they are not reflected in the benchmark scores. It offers 8 threads, which could help in heavily threaded applications, yet it still loses in multi-core tests. It includes integrated graphics, which the Xeon lacks, and its unlocked multiplier allows overclocking. Its lower TDP of 57 W makes it more power-efficient on paper, and its mobile socket (G3) targets laptops. However, the recorded data shows no scenario where the i7 outperforms the Xeon in Cinebench. For users who need integrated graphics or a mobile form factor, the i7-4940MX remains an option, but for raw processing performance, the Xeon E-2314 is the definitive winner.
