Intel Core i5-7500T vs Intel Xeon E3-1515M v5 Comparison

# Intel Core i5-7500T vs Intel Xeon E3-1515M v5

The Intel Core i5-7500T and Intel Xeon E3-1515M v5 are both 14nm Intel processors with four physical cores, but they target fundamentally different market segments—the i5-7500T is a 35W desktop part built for Socket 1151, while the Xeon E3-1515M v5 is a 45W server/workstation mobile processor on BGA 1440. Benchmark data shows a clear and consistent winner: the Xeon E3-1515M v5 takes all six head-to-head tests, with margins between 11.3% and 11.7% across Cinebench R15, R20, and R23 workloads. However, both processors occupy the same 38th percentile among all CPUs, and their average benchmark scores sit within 1.9% of each other, which suggests the performance gap is real but not transformative.

Where Each One Wins

The head-to-head results are unambiguous: the Intel Xeon E3-1515M v5 wins every single benchmark in the comparison set. It outperforms the Core i5-7500T in all six Cinebench tests—R15, R20, and R23, each in both multi-core and single-core variants. The Xeon's advantage ranges from an 11.3% lead in Cinebench R15 single-core to an 11.7% lead in both R20 single-core and R23 single-core. In multi-core tests, the Xeon holds a steady 11.6% advantage across all three Cinebench versions.

The Core i5-7500T, by contrast, wins no head-to-head benchmarks in this pairing. Its only statistical edge appears indirectly: the i5-7500T has an average benchmark score of 1483 across all tests, while the Xeon E3-1515M v5 averages 1456. This discrepancy arises because the i5-7500T includes Geekbench results (3062 multi-core, 1078 single-core) in its average, whereas the Xeon's benchmark set only covers Cinebench tests—the Geekbench scores are not present in the Xeon's data. When comparing only the shared Cinebench workloads, the Xeon is consistently ahead.

For use-case selection, the data points to the Xeon E3-1515M v5 for any workload where raw Cinebench performance matters, particularly threaded rendering. The i5-7500T's 35W TDP and Socket 1151 compatibility make it a plausible choice for low-power desktop builds, but the benchmark evidence shows it trails the Xeon in every measured compute task. The Xeon's ECC memory support and server/workstation market segment further position it for reliability-focused environments, though the i5-7500T's active production status and desktop orientation may appeal to system builders seeking a current, widely available part.

Architecture Differences

Both processors are built on Intel's 14nm process node, but they stem from different microarchitectures and platforms. The Core i5-7500T uses the Kaby Lake architecture (codename Kaby Lake), released in early 2017, while the Xeon E3-1515M v5 employs Skylake (codename Skylake-H), released roughly a year earlier in early 2016. This generational split explains some of the performance differences, though the Xeon's higher clocks and extra threads are more directly responsible.

The Xeon E3-1515M v5 has 8 threads versus the i5-7500T's 4 threads, a doubling that directly benefits multi-threaded workloads. The Xeon also runs at a higher base clock (2.80 GHz vs 2.70 GHz) and a higher boost clock (3.70 GHz vs 3.30 GHz), which contributes to its single-core superiority. Cache allocation differs as well: the Xeon carries 8 MB of shared L3 cache, while the i5-7500T has 6 MB. Both share identical L1 (64 KB per core) and L2 (256 KB per core) configurations.

Memory support marks another divergence. The i5-7500T supports only DDR4 with dual-channel memory and a theoretical bandwidth of 38.4 GB/s. The Xeon E3-1515M v5 supports both DDR3 and DDR4 (dual-channel), but its memory bandwidth is rated lower at 34.1 GB/s. The Xeon compensates with ECC memory support, a feature absent from the i5-7500T. Integrated graphics also differ: the i5-7500T pairs with HD 630, while the Xeon features Iris Pro Graphics P580. The Xeon's transistor count is listed at 2,300 million with a die size of 171 mm², while the i5-7500T's transistor and die size data are not provided.

The Xeon's socket (BGA 1440) is a ball-grid-array design, meaning it is soldered to the motherboard and not upgradeable, whereas the i5-7500T uses Socket 1151, a conventional LGA socket. Both processors have locked multipliers, so overclocking is not an option for either. The Xeon is marked as end-of-life in production status, while the i5-7500T remains active.

Head-to-Head Benchmarks

The Cinebench R15 multi-core test shows the Xeon E3-1515M v5 scoring 507 against the i5-7500T's 448, a delta of -11.6% from the i5's perspective. This 59-point gap represents the Xeon's thread advantage in action: 8 threads versus 4 threads at a 100 MHz higher base clock. The single-core R15 result narrows the margin slightly—71 vs 63, an 11.3% difference—indicating that the Xeon's higher boost clock (3.70 GHz vs 3.30 GHz) provides a meaningful single-thread uplift.

Moving to Cinebench R20, the Xeon scores 2115 multi-core versus the i5-7500T's 1870, again an 11.6% delta. The single-core R20 test produces a 298 vs 263 result, an 11.7% difference. These margins are remarkably consistent across R15 and R20, suggesting that the performance ratio between these two chips is stable regardless of workload intensity or renderer version.

Cinebench R23, the most recent test in the set, shows the Xeon at 5036 multi-core and the i5-7500T at 4454, preserving the 11.6% delta. The single-core R23 result is 711 for the Xeon and 628 for the i5-7500T, an 11.7% gap. Across all six comparisons, the Xeon's winning margin never deviates beyond 0.4 percentage points, which indicates a highly predictable performance relationship.

The nearest-rival data places both processors in similar company. The i5-7500T's closest rivals include the Intel Core i5-5575R (average score 1478, delta 0.4%), AMD Opteron 6344 (1492, -0.6%), Intel Core i5-4590S (1493, -0.6%), and Intel Core i7-4710HQ (1473, 0.7%). The Xeon E3-1515M v5 sits near the AMD Ryzen 3 PRO 2200GE (1461, -0.3%), Intel Core i3-7350K (1462, -0.4%), Intel Core i5-7300HQ (1448, 0.6%), and AMD Opteron 6378 (1447, 0.6%). Both chips cluster with mid-range processors from the same era, though the Xeon's average score of 1456 is slightly below the i5-7500T's 1483 due to the previously noted benchmark-set differences.
