Intel Core i5-9500T vs Intel Xeon D-1540 Comparison

The Intel Core i5-9500T and Intel Xeon D-1540 are both 14 nm Intel parts, but they target opposite ends of the computing spectrum. The i5-9500T is a 35 W desktop chip with six cores and integrated graphics, while the Xeon D-1540 is a 45 W server processor with eight cores and sixteen threads. Benchmark data shows the Xeon D-1540 winning all six head-to-head Cinebench tests, though by margins of only about 3% across the board. The i5-9500T counters with a higher single-core boost clock and consumer-oriented features, while the Xeon brings ECC memory support and more PCIe lanes. Their average benchmark scores are nearly identical, placing both in the late-40s percentile against all CPUs.

FAQ

Q: Which processor has more cores and threads?

A: The Intel Xeon D-1540 has 8 cores and 16 threads, while the Intel Core i5-9500T has 6 cores and 6 threads. The Xeon's hyper-threading doubles its thread count, giving it a significant advantage in heavily parallel workloads.

Q: How do their Cinebench R23 scores compare?

A: The Xeon D-1540 scores 8531 in multi-core and 1204 in single-core. The i5-9500T scores 8264 and 1166 respectively. The Xeon leads by 3.1% in multi-core and 3.2% in single-core, a surprisingly narrow margin given the core count difference.

Q: Which chip supports ECC memory?

A: The Intel Xeon D-1540 supports ECC memory, while the Intel Core i5-9500T does not. This makes the Xeon suitable for error-sensitive server and workstation environments where data integrity is critical.

Q: What are the integrated graphics options?

A: The i5-9500T includes Intel UHD Graphics 630, while the Xeon D-1540 has no integrated graphics at all. Systems built around the Xeon require a discrete GPU or a headless server setup.

Q: Do both processors use the same process node?

A: Yes, both are built on Intel's 14 nm process node. However, the i5-9500T uses the Coffee Lake architecture, while the Xeon D-1540 uses the older Broadwell architecture, which explains some of the performance characteristics.

Q: Which chip has a higher average benchmark score?

A: The i5-9500T has an average benchmark score of 2493, compared to 2467 for the Xeon D-1540. The i5 also sits at the 49th percentile versus the Xeon's 48th, meaning the desktop part edges out the server chip in aggregate performance.

Where Each One Wins

The Intel Xeon D-1540 wins on raw multi-threaded throughput in every recorded Cinebench test. Its 8-core, 16-thread configuration outperforms the i5-9500T's 6-core, 6-thread layout by roughly 3% in both multi-core and single-core workloads. The Xeon's lead appears consistent across all three Cinebench versions, with multi-core deltas of -3.1% in R15, -3.2% in R20, and -3.1% in R23, where negative deltaPct indicates the Xeon is the reference winner. This makes the Xeon the better choice for rendering, compilation, and heavy server workloads that scale with thread count.

The Intel Core i5-9500T wins on efficiency and platform flexibility. At 35 W TDP, it consumes 10 W less than the Xeon's 45 W rating. The i5 also includes integrated UHD Graphics 630, eliminating the need for a separate GPU in basic desktop systems. Its higher boost clock of 3.70 GHz versus the Xeon's 2.60 GHz gives it a theoretical advantage in bursty, lightly threaded tasks, even though Cinebench single-core scores show the Xeon ahead by about 3%. The i5's Socket 1151 platform is far more common than the Xeon's BGA 1667, making it easier to build and upgrade.

For systems requiring ECC memory or more PCIe lanes, the Xeon D-1540 is the clear winner. It supports both DDR3 and DDR4 memory with error correction, while the i5 is limited to non-ECC DDR4. The Xeon also provides 24 PCIe Gen 3 lanes versus the i5's 16, which matters for servers with multiple NVMe drives or network cards. The Xeon remains in active production, while the i5 is end-of-life, making the Xeon the safer long-term procurement choice for enterprise deployments.

Architecture Differences

The i5-9500T is built on the Coffee Lake architecture, specifically the Coffee Lake Refresh generation. It uses a monolithic die with six cores and no hyper-threading, resulting in six threads total. The Xeon D-1540 uses the Broadwell architecture, specifically Broadwell-DE, with eight cores and hyper-threading enabled for sixteen threads. Both use Intel's 14 nm process node and are fabricated by Intel, but the Xeon is the older design, released in 2015 versus the i5's 2018 launch.

Cache configurations differ significantly. The i5-9500T has 64 KB L1 and 256 KB L2 per core, plus a shared 9 MB L3 cache. The Xeon D-1540 also has 64 KB L1 and 256 KB L2 per core, but its L3 cache is allocated at 1.5 MB per core, totaling 12 MB across eight cores. This larger aggregate L3 cache benefits the Xeon in workloads with large working sets, though the per-core allocation is smaller than the i5's shared pool.

The Xeon D-1540 has a significantly larger physical die, measuring 246 mm² with 3,200 million transistors. The i5-9500T's die size and transistor count are not specified in the data. The Xeon's larger die reflects its additional cores and server-oriented features. Both chips are locked, with no unlocked multiplier for overclocking. The Xeon supports ECC memory and both DDR3 and DDR4, while the i5 only supports DDR4 without ECC. The Xeon also offers more PCIe lanes: 24 Gen 3 lanes versus 16 Gen 3 lanes on the i5.

Specification Differences

The core and thread counts differ substantially: the i5-9500T has 6 cores and 6 threads, while the Xeon D-1540 has 8 cores and 16 threads. Base clocks also diverge, with the i5 at 2.20 GHz and the Xeon at 2000.00 MHz (2.00 GHz). Boost clocks show a larger gap: the i5 boosts to 3.70 GHz, while the Xeon tops out at 2.60 GHz. TDP ratings are 35 W for the i5 and 45 W for the Xeon.

Memory support differs in both type and error correction. The i5 supports only DDR4 with dual-channel memory and a bandwidth of 42.7 GB/s. The Xeon supports both DDR3 and DDR4, also dual-channel, but its memory bandwidth is not specified. ECC memory is supported on the Xeon but not on the i5.

The socket and form factor are completely different. The i5 uses Intel Socket 1151, a standard desktop socket, while the Xeon uses Intel BGA 1667, which is soldered to the board. The Xeon has 24 PCIe Gen 3 lanes versus 16 on the i5. Integrated graphics are present only on the i5, which includes UHD Graphics 630; the Xeon has none. Market segments also differ: the i5 is a desktop part, while the Xeon is a server/workstation part. Production statuses differ as well, with the i5 marked end-of-life and the Xeon active.

Head-to-Head Benchmarks

The Xeon D-1540 wins all six head-to-head Cinebench comparisons, but the margins are remarkably consistent. In Cinebench R15, the Xeon scores 859 multi-core against the i5's 832, a delta of -3.1%. Single-core R15 sees the Xeon at 121 versus 117, a -3.3% delta. These are the largest margins in the entire comparison, yet still under 4%.

Cinebench R20 results follow the same pattern. The Xeon leads multi-core with 3583 versus 3470, a -3.2% delta. Single-core R20 has the Xeon at 505 versus 489, also a -3.2% delta. The consistency of these percentages suggests the Xeon holds a steady architectural advantage across different Cinebench versions, rather than a workload-specific edge.

Cinebench R23 closes the comparison with the tightest multi-core margin. The Xeon scores 8531 versus the i5's 8264, a -3.1% delta. Single-core R23 shows 1204 versus 1166, a -3.2% delta. Across all six tests, the Xeon's lead hovers between 3.1% and 3.3%, which is notable given that the Xeon has two more cores and ten more threads.

The i5-9500T counters in single-core performance outside the Cinebench suite. Its boost clock of 3.70 GHz is substantially higher than the Xeon's 2.60 GHz, and its Geekbench scores reflect this: the i5 scores 1198 single-core and 4407 multi-core, though no Geekbench data is available for the Xeon to make a direct comparison. The average benchmark scores also favor the i5, with 2493 versus 2467 for the Xeon, a 1% advantage. The i5's nearest rival is the Core i5-1155G7 with an average score of 2496, just 0.1% higher, while the Xeon's closest competitor is the Core i3-12100TE at 2475, 0.3% higher. Both chips sit in the 48th-49th percentile range, indicating they are mid-pack performers against the broader CPU landscape.
