Intel Core i7-4790K vs Intel Xeon Gold 6342 Comparison

The benchmark data presents a stark generational and market-segment divide. The Intel Xeon Gold 6342 is decisively superior in every measured multi-threaded and single-threaded workload, with a 6-0 sweep in head-to-head comparisons. The Intel Core i7-4790K, a desktop part from the Haswell era, is not competitive on raw performance; its only statistical relevance is its near-identical average benchmark score, which places it in the same 67th percentile, but this is an artifact of averaging disparate workload types. The choice between them is not about performance equivalence but about workload requirements and platform priorities.

Where Each One Wins

The Xeon Gold 6342 wins everywhere that compute throughput matters. In Cinebench R23 multi-core, it scores 40014 against the i7-4790K’s 6855, a delta of -82.9% for the older chip. This pattern repeats across all Cinebench versions: R15 multi-core (4033 vs 690), R20 multi-core (16805 vs 2879), and even single-core tests, where the Xeon’s 5649 in R23 single-core crushes the i7-4790K’s 967. The data shows no workload category where the i7-4790K takes a win; its sole advantage is architectural, not performance-based, requiring a different platform entirely.

The i7-4790K’s only meaningful edge is its 88 W TDP versus the Xeon’s 230 W, making it a lower-power option for legacy desktop builds. It also offers integrated graphics (Intel HD 4600), which the Xeon lacks entirely, and an unlocked multiplier for overclocking, a feature absent on the Xeon. For a user with an existing Socket 1150 motherboard and DDR3 memory, the i7-4790K remains a functional, if outdated, choice. But in absolute compute terms, the Xeon Gold 6342 wins all six head-to-head benchmarks by margins ranging from -82.9% to -83% in the i7-4790K’s favor (meaning the Xeon is roughly 5.8x faster in those tests).

Architecture Differences

The two processors come from fundamentally different eras and design philosophies. The i7-4790K is built on Intel’s 22 nm Haswell node, featuring 4 cores and 8 threads, while the Xeon Gold 6342 uses the 10 nm Ice Lake-SP architecture with 24 cores and 48 threads. The process node difference alone explains a significant portion of the performance gap, but the core count disparity (6x more cores) is the dominant factor in multi-threaded workloads.

Cache hierarchies differ sharply. Both share 64 KB of L1 per core, but the Xeon’s L2 is 1 MB per core versus the i7-4790K’s 256 KB per core. The L3 cache is 36 MB shared on the Xeon versus 8 MB shared on the i7-4790K. This 4.5x L3 advantage, combined with the newer architecture, gives the Xeon a massive edge in data-heavy server workloads. Memory support also diverges: the i7-4790K uses dual-channel DDR3 with 25.6 GB/s bandwidth, while the Xeon uses eight-channel DDR4 with 204.8 GB/s bandwidth — an 8x increase in theoretical memory throughput. The Xeon also supports ECC memory, a critical feature for server reliability that the i7-4790K lacks.

PCIe capabilities further separate them. The Xeon provides Gen 4 with 64 lanes (CPU only), while the i7-4790K offers Gen 3 with 16 lanes. This makes the Xeon suitable for multi-GPU or high-speed storage configurations, whereas the i7-4790K is limited to a single mainstream graphics card. The Xeon’s socket is Intel Socket 4189, a server platform, versus the desktop Intel Socket 1150. Production status also differs: the i7-4790K is end-of-life, while the Xeon remains active, indicating ongoing availability and support.

The Verdict

Pick the Intel Xeon Gold 6342 if you need maximum multi-threaded performance, memory bandwidth, or ECC reliability. The data shows it delivers 40014 in Cinebench R23 multi-core, a score that is 5.8x higher than the i7-4790K’s 6855. Its 24 cores and 48 threads, combined with 204.8 GB/s memory bandwidth, make it the only rational choice for server, workstation, or heavy content-creation workloads. The Xeon also wins single-core tests (5649 vs 967 in R23), so there is no scenario where the i7-4790K offers better raw speed.

Pick the Intel Core i7-4790K only if you are constrained to an existing legacy platform. Its 4 cores and 8 threads at a 4.40 GHz boost clock are sufficient for basic desktop tasks, and its 88 W TDP makes it easier to cool than the 230 W Xeon. The integrated Intel HD 4600 graphics eliminate the need for a discrete GPU in a simple build. However, the data is unambiguous: the i7-4790K loses every benchmark by over 82%, and its average benchmark score of 11745 is only 1.5% higher than the Xeon’s 11574 — a negligible difference that does not reflect real-world compute capability.

The Xeon’s nearest rival, the AMD Ryzen 9 PRO 7945, scores 11469 (0.9% lower), and the AMD EPYC 73F3 scores 11334 (2.1% lower), but neither appears in the head-to-head data. The i7-4790K’s closest competitors are the Intel Core i7-1185G7 (0.4% higher) and Intel Core i7-7700 (1.4% higher), which are also desktop parts. This reinforces that the i7-4790K belongs to a different performance class despite similar average scores.

FAQ

Q: Which processor is faster in multi-core workloads?

A: The Intel Xeon Gold 6342 is overwhelmingly faster. In Cinebench R23 multi-core, it scores 40014 versus the i7-4790K’s 6855, a -82.9% delta for the i7-4790K. The Xeon wins all multi-core tests by similar margins.

Q: Does the i7-4790K have any performance advantage?

A: No. The Xeon Gold 6342 wins all six head-to-head benchmarks, including single-core tests (Cinebench R23 single-core: 5649 vs 967). The i7-4790K’s only advantages are lower TDP (88 W vs 230 W), integrated graphics, and an unlocked multiplier.

A: The i7-4790K supports dual-channel DDR3 with 25.6 GB/s bandwidth. The Xeon Gold 6342 supports eight-channel DDR4 with 204.8 GB/s bandwidth and ECC memory, which the i7-4790K does not support.

Q: Are these processors comparable in average benchmark score?

A: Yes, their average scores are close: the i7-4790K scores 11745 and the Xeon Gold 6342 scores 11574, a 1.5% difference. Both are in the 67th percentile of all CPUs. However, this average masks the Xeon’s dominance in compute-heavy tests.

Q: Which processor has more cores and threads?

A: The Xeon Gold 6342 has 24 cores and 48 threads, while the i7-4790K has 4 cores and 8 threads. The Xeon also has a larger L3 cache (36 MB vs 8 MB) and per-core L2 (1 MB vs 256 KB).

A: No. The i7-4790K uses Intel Socket 1150, a desktop socket, while the Xeon Gold 6342 uses Intel Socket 4189 for server platforms. They are not interchangeable.

Head-to-Head Benchmarks

The Cinebench R15 multi-core test shows the Xeon Gold 6342 scoring 4033 against the i7-4790K’s 690, a -82.9% delta. This ratio is consistent across all multi-core tests: R20 (16805 vs 2879) and R23 (40014 vs 6855) all show the same -82.9% gap, indicating a fixed performance ratio of roughly 5.8x. The Xeon’s 24 cores and 48 threads scale almost linearly in these tests, while the i7-4790K’s 4 cores and 8 threads are saturated quickly.

Single-core results are equally one-sided. In Cinebench R15 single-core, the Xeon scores 569 versus the i7-4790K’s 97, a -83% delta. R20 single-core (2372 vs 406) and R23 single-core (5649 vs 967) show the same -82.9% pattern. This is notable because single-core performance is not purely core-count dependent; it reflects the Xeon’s newer 10 nm architecture and higher IPC. The i7-4790K’s 4.40 GHz boost clock is higher than the Xeon’s 3.50 GHz, but the architectural advantage of Ice Lake-SP more than compensates.

The largest absolute win for the Xeon is in Cinebench R23 multi-core, where it exceeds the i7-4790K by 33159 points. The smallest absolute difference is in R15 single-core, where the Xeon leads by 472 points. In every case, the deltaPct is approximately -83%, meaning the i7-4790K scores about 17% of the Xeon’s result. No benchmark reverses this trend; the winsB count is 6, and winsA is 0.
