Intel Core i5-7640X vs Intel Xeon D-1715TER Comparison

The Verdict

The recorded data presents a clear hierarchy between these two Intel processors. The Intel Xeon D-1715TER wins all six head-to-head benchmark comparisons against the Intel Core i5-7640X, with a consistent margin of 28.3% across every Cinebench test. This is not a narrow victory; it is a systematic advantage that repeats across single-core and multi-core workloads alike. Users who prioritize raw compute performance in Cinebench should select the Xeon D-1715TER without hesitation. The Core i5-7640X, despite its higher base and boost clocks, consistently trails in every measured metric.

However, the decision is not purely about benchmark scores. The two chips target entirely different market segments. The Xeon D-1715TER is a Server/Workstation part, built on a 10 nm process with 4 cores and 8 threads, while the Core i5-7640X is a Desktop part, built on a 14 nm process with 4 cores and 4 threads. The Xeon supports ECC memory and PCIe Gen 4, features that matter in server environments. The Core i5 has an unlocked multiplier, appealing to desktop overclockers. The data suggests that the Xeon is the superior compute engine, but the Core i5 retains relevance for desktop users who value its overclocking capability and quad-channel memory support. The average benchmark score reinforces this: the Xeon sits at 2238, while the Core i5 sits at 2167, a gap of about 3.3%. Both chips occupy the 47th percentile among all CPUs, indicating they are mid-pack performers overall, but within this pairing, the Xeon is the clear winner.

FAQ

A: The Xeon D-1715TER uses triple-channel memory and lists a memory bandwidth of 64.0 GB/s. The Core i5-7640X uses quad-channel memory, though its bandwidth figure is not recorded in the database.

Q: Which processor has a higher average benchmark score?

A: The Xeon D-1715TER has an average benchmark score of 2238, compared to 2167 for the Core i5-7640X. The Xeon's nearest rival, the Intel Xeon D-1548, scores 2231, just 0.3% behind, while the Core i5's nearest rival, the Intel Core i5-1145G7E, scores 2174, 0.3% ahead.

Architecture Differences

The two processors come from different architectural eras and are built on different manufacturing processes. The Xeon D-1715TER uses the Ice Lake architecture, specifically the Ice Lake-D codename, on a 10 nm process node. The Core i5-7640X uses the older Kaby Lake architecture, codenamed Kaby Lake-X, on a 14 nm process. This generational gap is reflected in their feature sets and efficiency profiles. The Xeon's 10 nm process allows for a significantly lower thermal design power of 50 watts, while the Core i5 draws 112 watts. Despite the lower power envelope, the Xeon delivers higher performance in all recorded benchmarks.

The Xeon D-1715TER belongs to the Xeon D (Ice Lake-D) generation, a server-focused lineup. It supports ECC memory, a critical feature for data integrity in server environments. Its PCIe implementation is Gen 4 with 16 lanes (CPU only). The Core i5-7640X, by contrast, belongs to the Core i5 (X-Series 7th Gen) generation, a desktop enthusiast platform. It supports PCIe Gen 3 and does not offer ECC memory. The Core i5 has an unlocked multiplier, enabling overclocking, while the Xeon's multiplier is locked.

Cache hierarchies also differ substantially. The Xeon D-1715TER has 80 KB of L1 cache per core and 1.25 MB of L2 cache per core, with 10 MB of shared L3 cache. The Core i5-7640X has 64 KB of L1 cache per core and 256 KB of L2 cache per core, with only 6 MB of shared L3 cache. The Xeon's larger cache allocations, particularly the 10 MB L3 versus 6 MB, likely contribute to its performance advantage. Both chips lack integrated graphics, and neither has a listed die size or transistor count in the database.

Specification Differences

The specification tables highlight several key differences beyond raw performance. The Xeon D-1715TER has a base clock of 2.40 GHz and a boost clock of 3.50 GHz. The Core i5-7640X has a much higher base clock of 3.90 GHz and a boost clock of 4.30 GHz. Despite the higher clocks, the Core i5 loses every benchmark, indicating that clock speed alone does not compensate for architectural and cache differences.

Power consumption differs dramatically. The Xeon D-1715TER has a TDP of 50 watts, while the Core i5-7640X has a TDP of 112 watts. This makes the Xeon more than twice as power-efficient in terms of performance per watt, given its superior scores. The Xeon uses an Intel BGA 2227 socket, a soldered server platform, while the Core i5 uses Intel Socket 2066, a desktop socket with replaceable processors. The Xeon supports triple-channel memory, while the Core i5 supports quad-channel memory. The Xeon lists a memory bandwidth of 64.0 GB/s; no bandwidth figure is recorded for the Core i5.

The Xeon D-1715TER has a release date of 2022-02-23, while the Core i5-7640X was released on 2017-06-25. The Xeon is currently marked as Active in production status, while the Core i5's production status is not recorded. The Xeon has a part number of SRLBX; the Core i5's part number is not recorded. The Xeon's market segment is Server/Workstation, and the Core i5's is Desktop. Neither processor has a launch MSRP recorded in the database.

Head-to-Head Benchmarks

The head-to-head results are remarkably consistent. Across all six Cinebench tests, the Xeon D-1715TER wins by exactly 28.3%. This uniformity suggests a fundamental architectural advantage rather than a workload-specific quirk. In Cinebench R23 multi-core, the Xeon scores 7738 versus 6031 for the Core i5. In R23 single-core, the Xeon scores 1092 versus 851. The pattern repeats in Cinebench R20: 3249 versus 2533 multi-core, and 458 versus 357 single-core. In Cinebench R15, the Xeon scores 779 versus 607 multi-core, and 109 versus 85 single-core.

The Core i5-7640X does have additional Geekbench scores recorded in the database: 5137 multi-core and 1736 single-core. The Xeon D-1715TER does not have Geekbench scores listed. However, this absence does not offset the Xeon's sweeping victory in the Cinebench suite. The Core i5's best performance relative to its rival comes in its average benchmark score, where it sits at 2167, about 3.3% behind the Xeon's 2238. Its nearest rivals include the Intel Core i5-1145G7E (2174, 0.3% ahead) and the AMD Ryzen 5 3400GE (2175, 0.3% ahead), indicating it is competitive within its own tier. The Xeon's nearest rivals include the Intel Xeon D-1548 (2231, 0.3% behind) and the AMD Ryzen 5 PRO 1500 (2246, 0.3% ahead), showing it sits in a similar performance band. The data is unambiguous: for users comparing these two specific chips, the Xeon D-1715TER is the faster processor in every recorded test, and the Core i5-7640X cannot close the gap despite its higher clocks and unlocked multiplier.
