Intel Core i3-9100T vs Intel Xeon D-1528 Comparison

The Verdict

The benchmark database places these two Intel parts at nearly the same overall performance tier, but they serve completely different roles. The Intel Core i3-9100T and Intel Xeon D-1528 both sit at a 35 W thermal envelope, yet the Xeon wins every single recorded benchmark in the head-to-head comparison. The data shows the Xeon D-1528 taking all six Cinebench tests, with margins ranging from 17.4% to 18.3% across both single-core and multi-core workloads. The Core i3-9100T is a desktop-oriented part with integrated graphics, while the Xeon D-1528 is a server/workstation chip without any graphics core. For buyers who need a low-power desktop processor with display output, the i3-9100T is the only choice between these two. For anyone building a headless server or embedded system that prioritizes raw compute throughput, the Xeon D-1528 delivers consistently higher scores. The database shows the Xeon achieving a 39th percentile ranking versus the i3's 39th percentile, meaning both are mid-pack performers overall, but the Xeon's 1677 average benchmark score edges out the i3's 1620 average.

Where Each One Wins

The Core i3-9100T has no benchmark wins in this comparison. It loses every single test in the head-to-head table. However, it wins on platform features that do not appear in raw compute scores. The i3-9100T includes Intel UHD Graphics 630, which means it can drive a display without a discrete GPU. The Xeon D-1528 has no integrated graphics at all. The i3 also uses the Intel Socket 1151, a mainstream desktop socket with broad motherboard availability, while the Xeon D-1528 uses Intel BGA 1667, which is a soldered ball-grid-array package typically found on embedded or server boards. The i3 was released later, in August 2018, versus the Xeon's October 2015 launch date. The i3 is also marked as end-of-life while the Xeon is still listed as active production. On the memory side, the i3 supports only DDR4, while the Xeon supports both DDR3 and DDR4. Both parts support ECC memory, which is unusual for a Core i3 part and is an important consideration for reliability-focused builds. The Xeon offers more PCIe lanes, 24 versus 16, making it better suited for expansion-heavy server workloads.

Architecture Differences

The two processors come from different Intel microarchitectures. The Core i3-9100T is built on Coffee Lake, specifically the Coffee Lake Refresh generation, while the Xeon D-1528 uses Broadwell, part of the Broadwell-DE family. Both are manufactured on the same 14 nm process node at Intel's foundry. The die sizes differ substantially: the i3 measures 126 mm² while the Xeon is much larger at 246 mm². The Xeon also packs 3,200 million transistors, a figure not provided for the i3. Core counts differ significantly: the i3 has 4 cores and 4 threads, while the Xeon has 6 cores and 12 threads thanks to Hyper-Threading. Clock speeds tell an interesting story. The i3 has a base clock of 3.10 GHz and a boost clock of 3.70 GHz, far higher than the Xeon's 1900.00 MHz base and 2.50 GHz boost. Despite the Xeon's lower clocks, its extra cores and threads allow it to outperform the i3 in every recorded test, including single-core tests where clock speed usually matters most. Cache layouts also differ: the i3 has 64 KB of L1 per core, 256 KB of L2 per core, and a shared 6 MB L3 cache. The Xeon has the same per-core L1 and L2 sizes but allocates 1.5 MB of L3 per core, which totals 9 MB across six cores. The Xeon's larger transistor count and die size reflect its server-oriented design with additional on-die features. PCIe connectivity favors the Xeon at 24 lanes versus the i3's 16 lanes, both on Gen 3. Memory bandwidth is only listed for the i3 at 38.4 GB/s; the Xeon's figure is not recorded in the database.

FAQ

Q: Which processor is faster in single-core performance?

A: The Intel Xeon D-1528 wins every single-core test. In Cinebench R23 single-core, it scores 818 versus the Core i3-9100T's 675, a 17.5% advantage.

Q: Does the Core i3-9100T have integrated graphics?

A: Yes, it includes Intel UHD Graphics 630. The Xeon D-1528 has no integrated graphics whatsoever, so it requires a discrete GPU or a headless setup.

Q: Can both processors use ECC memory?

A: Yes, both the Core i3-9100T and the Xeon D-1528 support ECC memory. This is notable because ECC support is rare on desktop-oriented Core i3 parts.

Q: What is the thermal design power of each chip?

A: Both processors have a 35 W TDP. They draw the same rated power despite the Xeon having 6 cores and 12 threads versus the i3's 4 cores and 4 threads.

Q: Which processor has more PCIe lanes?

A: The Xeon D-1528 provides 24 PCIe Gen 3 lanes, while the Core i3-9100T offers 16 PCIe Gen 3 lanes.

Q: How do their average benchmark scores compare?

A: The Xeon D-1528 has an average benchmark score of 1677, while the Core i3-9100T averages 1620. The Xeon also ranks at the 40th percentile versus all CPUs, compared to the i3's 39th percentile.

Head-to-Head Benchmarks

The head-to-head benchmark table shows a clean sweep for the Intel Xeon D-1528 across all six Cinebench tests. The margins are remarkably consistent, hovering around 17.5% in most cases. In Cinebench R15 multi-core, the Xeon scores 584 against the i3's 482, a 17.5% difference. The single-core R15 test shows the Xeon at 82 versus 67, an 18.3% gap, which is the largest margin in the entire comparison. Moving to Cinebench R20, the multi-core test has the Xeon at 2435 and the i3 at 2010, again a 17.5% delta. The R20 single-core test repeats the pattern: 343 for the Xeon and 283 for the i3, a 17.5% difference. In the most recent Cinebench R23 tests, the multi-core score shows the Xeon at 5799 versus 4788, a 17.4% margin. The R23 single-core test has the Xeon at 818 and the i3 at 675, which is a 17.5% gap. The consistency of these deltas is notable. It suggests the Xeon's advantage is structural, stemming from its 6-core, 12-thread configuration, rather than workload-specific. Even in single-core tests, where the i3's higher clock speeds should help, the Xeon still prevails by roughly the same margin. This points to the Xeon's Broadwell architecture having superior per-clock efficiency, or the recorded boost behavior favoring the Xeon in sustained loads. The Core i3-9100T does have a Geekbench multi-core score of 3443 and a single-core score of 1215 recorded in its benchmark list, but the Xeon has no Geekbench scores in the database, so no direct comparison is possible on that test suite. The overall picture is clear: the Xeon D-1528 is the faster processor in every measurable compute test, while the i3-9100T remains the practical choice for desktop systems needing integrated graphics and a standard socket. The Xeon's nearest rivals in the database include the Intel Core i5-4690K at 1682 average score, a 0.3% difference, and the Intel Core i7-3770K at 1688, a 0.6% difference, showing the Xeon slots into a familiar performance bracket. The i3-9100T's nearest rivals include the Intel Core i7-970 at 1613, a 0.4% difference, and the Intel Pentium Gold G7400T at 1628, a 0.5% difference, placing it at the edge of a similar performance tier.
