Intel Core i5-7600K vs Intel Xeon E3-1285L v4 Comparison

Head-to-Head Benchmarks

The recorded Cinebench data gives the Intel Xeon E3-1285L v4 a clean sweep across all six head-to-head comparisons. The Xeon wins every multi-core and single-core test by a margin that stays remarkably consistent, between 18.3% and 18.9%. In Cinebench R15 multi-core, the Xeon scores 693 against the Core i5-7600K’s 583, an 18.9% advantage. The single-core R15 result follows the same pattern: 97 versus 82, a delta of 18.3%. This consistency suggests the performance gap is structural rather than workload-specific.

Moving to Cinebench R20, the Xeon again leads by 18.9% in multi-core with a score of 2891 versus 2432. The single-core R20 result is 407 against 343, an 18.7% margin. The latest Cinebench R23 test reinforces the trend: the Xeon posts 6884 in multi-core versus 5792, another 18.9% delta, and 971 versus 817 in single-core, an 18.8% gap. The fact that the margin barely moves from R15 to R23 indicates that the Xeon’s advantage is not tied to any particular rendering workload or software version.

The Core i5-7600K does have one benchmark in the database that the Xeon lacks: Geekbench multi-core at 4239 and single-core at 1522. Without a corresponding Geekbench score for the Xeon, a direct comparison in that test is not possible from the recorded data. The Xeon’s six wins stand against zero for the i5 in the shared benchmark suite. The average benchmark score tells a similar story, with the Xeon at 1991 and the i5 at 1976, a slim 0.8% difference in aggregate, though this includes the i5’s Geekbench results which the Xeon does not have.

FAQ

Q: Which CPU wins the Cinebench R23 multi-core test, and by how much?

A: The Intel Xeon E3-1285L v4 wins with a score of 6884 against the Core i5-7600K’s 5792, an 18.9% advantage.

Q: Is the Xeon also faster in single-core workloads?

A: Yes. The Xeon leads in all three single-core Cinebench tests: R15 at 97 versus 82 (18.3%), R20 at 407 versus 343 (18.7%), and R23 at 971 versus 817 (18.8%).

Q: Does the Core i5-7600K win any benchmark in the head-to-head data?

A: No. The database records zero wins for the i5-7600K across the six shared Cinebench tests. The i5 does have Geekbench scores of 4239 multi-core and 1522 single-core, but there is no matching Geekbench result for the Xeon in the recorded data.

Q: Which CPU has a higher average benchmark score?

A: The Xeon E3-1285L v4 has an average benchmark score of 1991, slightly above the i5-7600K’s 1976. The difference is only 0.8%.

Q: How does the Xeon’s performance compare to its nearest rivals in the database?

A: The Xeon E3-1285L v4 sits at the 44th percentile among all CPUs. Its closest rival, the AMD Ryzen 5 1500X has an average score of 1992, a delta of 0%. The Intel Core i7-7920HQ matches at 1992 with a -0.1% delta, and the Intel Xeon E3-1585L v5 trails at 1989 with a 0.1% delta.

Architecture Differences

The Xeon E3-1285L v4 is built on Intel’s Broadwell architecture, specifically the Broadwell-DT codename, and belongs to the Xeon E3 (Broadwell-DT generation. The Core i5-7600K uses the Kaby Lake architecture with the Kaby Lake codename and comes from the Core i5 (Kaby Lake) generation. Both CPUs use a 14 nm process node from Intel, but the Xeon adds details the i5 lacks entirely. The Xeon has transistor count listed at 1,400 million transistors and a die size of 160 mm². The i5 has no recorded transistor count, die size, or die size data in the database.

Cache layout is identical in structure: 64 KB of L1 per core and 256 KB of L2 per core, with 6 MB of shared L3 for both processors. The Xeon supports DDR3 memory, while the i5 supports DDR4. This difference affects memory bandwidth: the Xeon reaches 29.9 GB/s, the i5 reaches 38.4 GB/s. Both are dual-channel designs. The Xeon supports ECC memory, the i5 does not. The integrated graphics differ as well: the Xeon features Intel Iris Pro P6300, while the i5 has HD 630. The Xeon is classified for the server and workstation market segment, while the i5 targets desktop.

Specification Differences

The two CPUs diverge on several key specification fields. The Xeon E3-1285L v4 has 4 cores and 8 threads, while the Core i5-7600K has 4 cores and 4 threads. Base clock speeds differ: the Xeon runs at 3.40 GHz, the i5 at 3.80 GHz. Boost clocks also differ: the Xeon reaches 3.80 GHz, the i5 reaches 3.80 GHz. The Xeon has a TDP of 65 W, while the i5 has a 91 W TDP, a substantial power envelope difference.

Sockets are not shared: the Xeon uses Intel Socket 1150, the i5 uses Intel Socket 1151. The memory type differs, with the Xeon on DDR3 and the i5 on DDR4, and the measured memory bandwidth reflects that, 29.9 GB/s versus 38.4 GB/s. ECC support is present only on the Xeon. The i5 has an unlocked multiplier, making it overclockable, while the Xeon’s multiplier is locked. The market segment separates the two: the Xeon is server and workstation oriented, the i5 is desktop oriented. The production status also differs: the Xeon is end-of-life, the i5 is listed as active. The release dates place the Xeon in June 2015 and the i5 in January 2017. The launch MSRP for the Xeon is $445; the i5 has no recorded launch MSRP. The Xeon’s part number is SR2B1, the i5’s is SR32V. The PCIe specification is Gen 3 for both, but the i5 notes 16 lanes (CPU only) while the Xeon simply lists Gen 3.

Where Each One Wins

The Xeon E3-1285L v4 wins in threaded rendering workloads. Its 8 threads give it a clear edge over the i5-7600K’s 4 threads, and the Cinebench multi-core results confirm this: an 18.9% margin in R15, R20, and R23. The Xeon also wins single-core tests, which is more surprising given its lower base and boost clocks. The Xeon’s 3.40 GHz base and 3.80 GHz boost trail the i5’s 3.80 GHz base and 4.20 GHz boost, yet the Xeon still posts 18.3% to 18.8% single-core advantages in Cinebench. The data suggests the Broadwell architecture extracts more instructions per clock than the higher-clocked Kaby Lake design. For server and workstation users, the Xeon also offers ECC memory support, a feature absent on the i5, and does so at a lower TDP of 65 W versus 91 W. The Xeon’s Iris Pro P6300 integrated graphics is a more capable iGPU tier than the HD 630.

The Core i5-7600K’s wins are narrower and more situational. It has a higher base clock and boost clock, and the recorded Geekbench scores of 4239 multi-core and 1522 single-core are present in the database, though they cannot be compared directly to the Xeon without a matching Geekbench score. The i5 supports DDR4 memory with a higher bandwidth of 38.4 GB/s, which may benefit memory-sensitive tasks. The unlocked multiplier is a clear advantage for enthusiasts who want to push clocks beyond stock, something the locked Xeon cannot offer. The i5 is also listed as active production, while the Xeon is end-of-life, which matters for availability and long-term system planning. The i5’s active status and overclocking headroom make it a reasonable pick for desktop builders who prioritize clock speed flexibility, but the benchmark data shows no measured workload where the i5 beats the Xeon.
