CPU Comparison

The Intel Xeon D-1528 and Intel Core i7-6700TE are both 35 W processors aimed at different corners of the market, yet benchmark data shows a consistent, if modest, performance advantage for the Xeon. Across every head-to-head benchmark recorded, the Xeon D-1528 finishes ahead, making the comparison less about raw speed and more about platform-level trade-offs like memory support, integrated graphics, and socket compatibility. The data is unambiguous: the Xeon D-1528 wins all six tests, while the Core i7-6700TE records zero victories.

Head-to-Head Benchmarks

The most striking pattern in the benchmark results is the uniformity of the Xeon D-1528's lead. In Cinebench R15, the Xeon scores 584 in multi-core against the Core i7-6700TE's 531, a 10% advantage. The single-core R15 result is similarly lopsided: 82 versus 74, a 10.8% delta. This is not a case where one chip wins on multi-threaded workloads and the other claws back ground in lightly-threaded tasks; the Xeon D-1528 dominates both.

That trend continues into newer Cinebench versions. In Cinebench R20, the Xeon D-1528 posts 2435 multi-core and 343 single-core, compared to 2214 and 312 for the Core i7-6700TE. The deltas are 10% and 9.9%, respectively. Cinebench R23 tells the same story: the Xeon's 5799 multi-core score beats the Core i7's 5273 by 10%, and its 818 single-core score beats 744 by 9.9%. The consistency of these margins, hovering around 10% across every test, suggests a fundamental per-core efficiency advantage for the Xeon D-1528, not just a core-count benefit.

Interestingly, the Core i7-6700TE has additional Geekbench results in its benchmark list, 3154 multi-core and 1028 single-core, but the Xeon D-1528 has no corresponding Geekbench entries, so those scores cannot be compared directly. The available head-to-head data is exclusively Cinebench, and it is entirely one-sided.

The overall average benchmark scores reflect this narrow but consistent gap. The Xeon D-1528 averages 1677 across all its benchmarks, while the Core i7-6700TE averages 1666. That is a 0.6% difference in the aggregate, which is far smaller than the 10% margins seen in individual Cinebench tests. This discrepancy arises because the Xeon's average includes no Geekbench results, while the Core i7's average is pulled down by its lower Geekbench scores relative to its Cinebench performance. In the direct head-to-head tests, the Xeon's lead is clear and repeatable.

Where Each One Wins

Based strictly on the benchmark data, the Xeon D-1528 wins every measurable performance category. It holds a 10% edge in multi-core Cinebench R15, R20, and R23, and a slightly larger 9.9% to 10.8% edge in single-core versions of those same tests. There is no test in the head-to-head set where the Core i7-6700TE comes out ahead.

That said, the Core i7-6700TE has advantages that are not captured by Cinebench scores. It includes integrated HD Graphics 530, whereas the Xeon D-1528 has no integrated graphics listed. For a system that needs display output without a discrete GPU, the Core i7 is the only viable option. The Core i7 also has a higher base clock of 2.40 GHz and boost clock of 3.40 GHz, compared to the Xeon's 1.90 GHz and 2.50 GHz, which could translate to better responsiveness in workloads that are not well-represented by Cinebench's rendering-oriented tests. The Xeon compensates with 6 cores and 12 threads versus the Core i7's 4 cores and 8 threads, which explains its multi-core lead despite lower clock speeds.

The Xeon D-1528 also supports ECC memory, a feature entirely absent from the Core i7-6700TE. That makes the Xeon appropriate for server or workstation environments where data integrity is critical. The Core i7, with its desktop socket and integrated graphics, is better suited to compact or embedded desktop builds where the CPU's lower thread count is acceptable.

Specification Differences

The two processors differ in nearly every physical and platform specification. The Xeon D-1528 uses 6 cores and 12 threads, versus 4 cores and 8 threads on the Core i7-6700TE. Base clocks are 1.90 GHz for the Xeon and 2.40 GHz for the Core i7; boost clocks are 2.50 GHz and 3.40 GHz, respectively. Both have a 35 W TDP.

The sockets are incompatible: the Xeon D-1528 uses Intel BGA 1667, while the Core i7-6700TE uses Intel Socket 1151. Memory support also differs. The Xeon supports both DDR3 and DDR4, while the Core i7 supports only DDR4. The Xeon has ECC memory support; the Core i7 does not. PCIe lane counts differ as well, with the Xeon offering Gen 3 with 24 lanes versus the Core i7's Gen 3 with 16 lanes. The Core i7 includes integrated HD Graphics 530, while the Xeon has none. The Xeon has a launch MSRP of $320; the Core i7's launch MSRP is not listed.

Cache configurations are notably different. Both have 64 KB L1 and 256 KB L2 per core, but the Xeon has 1.5 MB of L3 per core, while the Core i7 has 8 MB of shared L3. The Core i7 lists a memory bandwidth of 34.1 GB/s, while the Xeon does not list a bandwidth figure.

Architecture Differences

The two chips come from different Intel microarchitectures. The Xeon D-1528 is based on Broadwell, specifically the Broadwell-DE generation, built on a 14 nm process with 3,200 million transistors on a 246 mm² die. The Core i7-6700TE is Skylake-based, also on 14 nm, but transistor count and die size are not listed in the data.

The core topology differs beyond raw counts. The Xeon's L3 cache is allocated per core at 1.5 MB each, implying a total of 9 MB across six cores, though the total is not explicitly stated. The Core i7 uses a shared 8 MB L3 cache, which is a classic desktop arrangement. This structural difference, combined with the Xeon's two extra cores, explains its consistent multi-core advantage.

The memory controllers reflect their intended markets. The Xeon's support for both DDR3 and DDR4, along with ECC, points to a flexible server/embedded design. The Core i7's exclusive DDR4 support and lack of ECC align with mainstream desktop use. The Xeon's 24 PCIe lanes versus the Core i7's 16 further reinforce the server orientation. The Core i7's integrated graphics are a clear architectural addition for desktop systems that lack a discrete GPU, whereas the Xeon omits this entirely.

The Verdict

The benchmark data is decisive: the Intel Xeon D-1528 outperforms the Intel Core i7-6700TE in every recorded head-to-head test, with margins between 9.9% and 10.8%. Any user prioritizing raw Cinebench performance, whether single-core or multi-core, should choose the Xeon D-1528 without hesitation. Its 6-core, 12-thread configuration combined with a per-core advantage over the Core i7 makes it the stronger processor in both lightly-threaded and heavily-threaded scenarios.

However, the choice is not purely about benchmark scores. The Core i7-6700TE is the only one of the two with integrated graphics, making it the sole option for systems that require on-chip display output. It also has higher clock speeds, which could benefit certain latency-sensitive applications not captured by Cinebench. The Xeon counters with ECC memory support, dual-generation memory compatibility, and more PCIe lanes, making it the appropriate pick for servers, workstations, or embedded deployments where reliability and expandability matter more than integrated graphics.

For a desktop user building a compact system with no discrete GPU, the Core i7-6700TE is the practical choice despite its lower scores. For anyone running a server or workstation where ECC memory and additional PCIe lanes are required, the Xeon D-1528 is the clear winner, and it happens to also be faster in every benchmark measured. The data favors the Xeon; the only reasons to choose the Core i7 are platform features the Xeon simply does not offer.
