Intel Core i5-3570T vs Intel Xeon D-1518 Comparison

Head-to-Head Benchmarks

The recorded data paints a clear picture: the Intel Xeon D-1518 dominates the Intel Core i5-3570T across every single benchmark in the head-to-head comparison. The Xeon D-1518 wins all five recorded tests, with the Core i5-3570T failing to secure a single victory. The margins are remarkably consistent, hovering near 15% across both multi-core and single-core workloads.

In Cinebench R15 multi-core, the Xeon D-1518 scores 390 against the i5-3570T’s 331, a 15.1% advantage. Moving to Cinebench R20 multi-core, the Xeon posts 1628 versus 1383, a 15% lead. The multi-core gap persists in Cinebench R23, where the Xeon reaches 3877 compared to 3293, again 15.1% ahead. These consistent deltas suggest a structural advantage rather than a workload-specific quirk.

Single-core performance tells a similar story, though the margins are slightly narrower. In Cinebench R20 single-core, the Xeon D-1518 scores 229 against 195 for the i5-3570T, a 14.8% edge. Cinebench R23 single-core shows the Xeon at 547 versus 465, a 15% improvement. The i5-3570T’s higher boost clock of 3.30 GHz (the Xeon has no listed boost clock) is not enough to overcome the architectural gap.

The Xeon D-1518 also posts a higher average benchmark score of 1121, though the i5-3570T sits slightly higher at 1136. This discrepancy is explained by the i5-3570T’s inclusion of Geekbench results, which the Xeon lacks in the database. Both processors land in the 32nd percentile of all CPUs, indicating they occupy a similar overall performance tier despite the Xeon’s clear head-to-head superiority.

Where Each One Wins

The Xeon D-1518 wins everywhere the data records a direct comparison. Its multi-threaded advantage stems from 8 threads versus 4, doubling the logical core count. This translates to a 15.1% lead in Cinebench R15 multi-core, 15% in R20 multi-core, and 15.1% in R23 multi-core. For threaded workloads like rendering, compiling, or server-side tasks, the Xeon is consistently faster.

Single-core results also favor the Xeon D-1518, despite the i5-3570T’s higher boost clock. The Xeon’s 14.8% lead in R20 single-core and 15% in R23 single-core suggest its Broadwell architecture extracts more instructions per clock than the older Ivy Bridge design. This makes the Xeon the better choice even for lightly threaded applications.

The i5-3570T does have one indirect advantage: it includes integrated graphics (Intel HD 2500), while the Xeon D-1518 has none. For systems requiring a display output without a discrete GPU, the i5-3570T is the only viable option. The i5-3570T also carries a Geekbench multi-core score of 1705 and single-core of 578, whereas no Geekbench results exist for the Xeon in the database, leaving that comparison unresolved.

The Xeon’s ECC memory support and 24 PCIe lanes (versus 16 for the i5) position it for reliability-focused server roles. The i5-3570T, with its desktop socket and integrated graphics, suits basic desktop builds. The data shows no benchmark scenario where the i5-3570T outperforms the Xeon D-1518.

Architecture Differences

The two processors come from different Intel generations and manufacturing nodes. The Core i5-3570T uses Ivy Bridge architecture on a 22 nm process, while the Xeon D-1518 uses Broadwell architecture on a 14 nm node. This node advantage contributes to the Xeon’s higher transistor count: 3,200 million versus 1,400 million for the i5. The Xeon’s die size is also larger at 246 mm² compared to 160 mm².

Both processors feature 4 physical cores, but the Xeon D-1518 doubles the thread count to 8 via Hyper-Threading, while the i5-3570T is limited to 4 threads. Cache configurations differ notably. The i5-3570T has 6 MB of shared L3 cache, while the Xeon D-1518 allocates 1.5 MB of L3 per core, totaling 6 MB across four cores. Both share 64 KB L1 and 256 KB L2 per core.

Memory support diverges: the i5-3570T supports only DDR3, while the Xeon D-1518 supports both DDR3 and DDR4. Both use dual-channel memory buses. The Xeon adds ECC memory support, a critical feature for server reliability, which the i5 lacks. PCIe lane counts also differ: the Xeon provides 24 Gen 3 lanes (CPU only) versus 16 for the i5.

Thermal and power profiles shift as well. The Xeon D-1518 has a 35 W TDP, lower than the i5-3570T’s 45 W, despite the Xeon’s higher performance. This efficiency comes from the newer 14 nm process. The i5-3570T uses the Intel Socket 1155, while the Xeon D-1518 uses Intel BGA 1667, indicating a soldered, embedded-style design for the latter.

The Xeon D-1518 remains in active production, while the i5-3570T’s production status is not recorded. Release dates differ by nearly three years: the i5-3570T launched on 2012-04-28, the Xeon D-1518 on 2015-03-08. The Xeon’s launch MSRP is $193, though the i5 has no recorded MSRP.
