Intel Core i5-7500T vs Intel Xeon E3-1225 v5 Comparison

The Intel Core i5-7500T and Intel Xeon E3-1225 v5 are both quad-core, four-thread processors on the Intel Socket 1151 platform, but they target very different market segments. The i5-7500T is a 35 W Kaby Lake desktop chip with integrated HD 630 graphics, while the Xeon E3-1225 v5 is an 80 W Skylake-DT server/workstation part with ECC memory support and a $224 launch MSRP. Benchmark data shows a decisive performance gap favoring the Xeon, but the i5-7500T’s efficiency profile tells a different story.

Head-to-Head Benchmarks

The Xeon E3-1225 v5 wins every single benchmark in the head-to-head comparison, taking all six tests by a remarkably consistent margin. In Cinebench R15 multi-core, the Xeon scores 510 against the i5-7500T’s 448, a 12.2% advantage. The single-core R15 test follows the same pattern: 72 versus 63, a 12.5% lead for the Xeon. This consistency suggests the gap is structural rather than workload-specific.

Moving to Cinebench R20, the Xeon again dominates. Its multi-core score of 2127 beats the i5-7500T’s 1870 by 12.1%, while the single-core result of 300 versus 263 represents a 12.3% edge. The newest Cinebench R23 test shows the same story: the Xeon scores 5065 multi-core against 4454, a 12.1% difference, and 715 single-core versus 628, a 12.2% margin.

The deltas are almost perfectly uniform across all six benchmarks, ranging only from 12.1% to 12.5%. This uniformity indicates that the Xeon’s advantage comes from raw clock speed rather than any architectural efficiency. The Xeon’s 3.30 GHz base clock and 3.70 GHz boost clock are substantially higher than the i5-7500T’s 2.70 GHz base and 3.30 GHz boost, explaining the near-constant 12% gap.

For the i5-7500T, there are no benchmark wins to highlight. Its average benchmark score of 1483 places it at the 38th percentile among all CPUs, with nearest rivals including the Intel Core i5-5575R (1478, 0.4% ahead), AMD Opteron 6344 (1492, 0.6% behind), and Intel Core i5-4590S (1493, 0.6% behind). The Xeon’s average score of 1465 also lands at the 38th percentile, with rivals like the Intel Core i3-7350K (1462, 0.2% ahead) and AMD Ryzen 3 PRO 2200GE (1461, 0.3% ahead) in close proximity.

Both processors sit in the same percentile band, meaning neither is an outlier in the broader CPU landscape. But head-to-head, the Xeon’s higher clock speeds translate directly into measurable performance superiority across every rendering workload tested.

Where Each One Wins

The benchmark results paint a clear picture: the Xeon E3-1225 v5 wins in every compute category tested. For multi-threaded workloads, it delivers 12.1-12.2% higher scores across Cinebench R15, R20, and R23, making it the stronger choice for rendering, video encoding, or any task that scales across all four cores. Single-threaded performance is equally lopsided, with the Xeon leading by 12.2-12.5% in all three Cinebench single-core tests, which matters for lightly-threaded applications or tasks with serial bottlenecks.

The i5-7500T’s only advantage is not visible in these benchmarks but is clear from its specifications. Its 35 W TDP is less than half the Xeon’s 80 W TDP, allowing for smaller, quieter cooling solutions and lower power draw in sustained workloads. This makes the i5-7500T a better fit for compact desktop builds or systems where thermal headroom is limited, even though it sacrifices 12% performance across the board.

For memory flexibility, the Xeon supports both DDR3 and DDR4, while the i5-7500T is limited to DDR4. However, the i5-7500T has a higher memory bandwidth rating at 38.4 GB/s versus the Xeon’s 34.1 GB/s, and both run dual-channel configurations. The Xeon also includes ECC memory support, a critical feature for error-sensitive server and workstation environments that the i5-7500T lacks entirely.

Integrated graphics differ as well: the i5-7500T uses HD 630, while the Xeon pairs with HD Graphics P530. Neither is a gaming powerhouse, but both provide basic display output. The Xeon’s server classification and end-of-life production status contrast with the i5-7500T’s active desktop status, suggesting the i5 is the more practical choice for new consumer builds despite its slower clocks.

The Verdict

The data is unambiguous: the Intel Xeon E3-1225 v5 outperforms the Intel Core i5-7500T in every benchmark recorded, with margins between 12.1% and 12.5%. For users who prioritize raw compute performance in Cinebench workloads, the Xeon is the clear choice, despite its 80 W TDP and end-of-life status. Its 8 MB shared L3 cache versus the i5-7500T’s 6 MB, combined with higher base and boost clocks, delivers consistent wins across all six tests.

The i5-7500T is the better option only when power efficiency is paramount. Its 35 W TDP enables a smaller thermal footprint, and its active production status means it remains a current product. For a compact desktop where rendering performance is secondary to low power draw and quiet operation, the i5-7500T’s 12% deficit may be acceptable.

Server or workstation builders should choose the Xeon without hesitation. Its ECC memory support alone justifies its selection for data-integrity-critical applications, and the performance edge in both multi-core and single-core tests reinforces that decision. Consumers building a general-purpose desktop who never touch server features will find the i5-7500T adequate, but benchmark results show they are leaving measurable performance on the table.

The Xeon’s $224 launch MSRP, stated once here, positions it as a premium part, but the data shows the premium buys real performance. The i5-7500T, with no launch MSRP listed, competes on efficiency rather than speed. For most compute-bound tasks, the Xeon E3-1225 v5 is the data-backed winner.

A: The i5-7500T has a 35 W TDP, while the Xeon E3-1225 v5 has an 80 W TDP. The i5-7500T’s rating is less than half the Xeon’s, offering significantly lower power draw.

Q: Which processor has a larger L3 cache?

A: The Xeon E3-1225 v5 has 8 MB of shared L3 cache, compared to the i5-7500T’s 6 MB. Both feature 64 KB L1 and 256 KB L2 cache per core.

Q: Are both processors on the same socket?

A: Yes, both use Intel Socket 1151. The i5-7500T is based on Kaby Lake architecture, while the Xeon E3-1225 v5 uses Skylake-DT architecture, with both built on Intel’s 14 nm process node.

Architecture Differences

The two processors share a common foundation: both are Intel Socket 1151 parts with four cores and four threads, built on a 14 nm process node at Intel’s foundry. Both use a dual-channel memory bus with 16 PCIe Gen 3 lanes from the CPU. The similarities end there, as architectural choices diverge significantly.

The i5-7500T uses Kaby Lake architecture, while the Xeon E3-1225 v5 is built on Skylake-DT. Both are quad-core designs without hyper-threading, but the Xeon’s Skylake lineage targets server reliability, evidenced by its ECC memory support and DDR3/DDR4 compatibility. The i5-7500T supports only DDR4, a consumer-oriented simplification. Memory bandwidth favors the i5-7500T at 38.4 GB/s versus the Xeon’s 34.1 GB/s, though the Xeon’s ECC capability may be more critical for certain workloads.

Cache hierarchies differ in the shared L3 tier: the i5-7500T has 6 MB, while the Xeon has 8 MB, a 33% advantage for the server chip. Both use 64 KB L1 and 256 KB L2 per core, so the extra L3 is the key cache difference. Clock speeds strongly favor the Xeon, with a 3.30 GHz base and 3.70 GHz boost versus the i5-7500T’s 2.70 GHz base and 3.30 GHz boost, explaining the benchmark gap.

The Xeon’s transistor count of 1,750 million and die size of 122 mm² are listed, while the i5-7500T’s are not provided. The Xeon’s die is a Skylake-DT design, and its integrated graphics is HD Graphics P530, compared to the i5-7500T’s HD 630. The Xeon is classified as server/workstation with an end-of-life production status, while the i5-7500T is an active desktop part. The Xeon’s part number is SR2LJ; the i5-7500T’s is SR337. Neither processor has an unlocked multiplier, so overclocking is not an option for either. The Xeon’s $224 launch MSRP contrasts with the i5-7500T’s lack of a listed MSRP, and the Xeon’s release date of 2015-10-18 precedes the i5-7500T’s 2017-01-02 release.
