Intel Core i7-8750H vs Intel Xeon 6315P Comparison

Head-to-Head Benchmarks

The Intel Xeon 6315P and Intel Core i7-8750H present a study in contrasting design priorities. The Xeon 6315P dominates the head-to-head record with 14 wins out of 17 benchmark comparisons, while the i7-8750H manages 3 wins. The most striking result is in PassMark's find prime numbers test, where the Xeon scores 150 against the i7's 27, a 455.6% advantage. This is the largest single delta in the entire comparison and highlights the Xeon's raw arithmetic throughput.

In rendering workloads, the Xeon 6315P maintains a consistent edge. Across Cinebench R15, R20, and R23, the multicore deltas are remarkably stable: 22.4%, 22.5%, and 22.5% respectively. The single-core deltas are nearly identical, with R15 at 23.1%, R20 at 22.4%, and R23 at 22.4%. The Xeon's single-thread PassMark score of 3795 versus 2276 for the i7 represents a 66.7% gap, a much larger proportional difference than the Cinebench results suggest.

Encryption and floating-point workloads heavily favor the Xeon. Data encryption shows a 61.5% delta (5470 versus 3388), while floating-point math delivers a 51% advantage (33496 versus 22179). Physics simulation is another notable win for the Xeon: 1156 versus 604, a 91.4% delta. Extended instructions also go to the Xeon, with 10539 versus 8637, a 22% margin.

The Core i7-8750H claims its wins in three specific PassMark tests. Data compression favors the i7 by 15.1% (139418 versus 118313). Integer math sees the i7 at 35629 versus 27046, a 24.1% advantage. Random string sorting goes to the i7 by 22.2% (18622 versus 14487). These outcomes indicate the i7's higher core count and thread count can be leveraged in workloads that scale well with parallel resources.

The overall average benchmark scores place the Xeon at 14574 and the i7 at 13868. The Xeon's percentile ranking is 69 versus 68 for the i7, a narrow margin despite the 14-to-3 win tally. Looking at the nearest rivals in the database, the Xeon 6315P sits alongside the AMD EPYC 7473X at exactly 0% delta, and is 0.1% behind the AMD Ryzen 5 5500U and 0.2% behind the Intel Core i5-9600K. The i7-8750H, meanwhile, sits 0.5% behind the AMD EPYC 7443 and 1.2% behind the Intel Core i5-10400, while leading the AMD Ryzen Threadripper PRO 3975WX by 0.6% and the Intel Core 3 304 by 0.9%.

Where Each One Wins

The Intel Xeon 6315P is the clear choice for compute-heavy, single-thread-sensitive, and encryption-focused tasks. Its 66.7% lead in PassMark single-thread performance and 61.5% lead in data encryption make it suitable for workloads that depend on per-core efficiency and cryptographic throughput. The 455.6% advantage in prime number finding further cements its position for mathematical and scientific computing. The 51% edge in floating-point math and 91.4% lead in physics simulation point to strength in simulation and modeling environments.

The Core i7-8750H, despite its age and mobile pedigree, wins in integer math, data compression, and random string sorting. The 24.1% lead in integer math suggests that its 6 cores and 12 threads provide a meaningful parallel advantage for integer-heavy code. The 15.1% win in data compression and 22.2% win in random string sorting indicate that the i7 handles memory-intensive, parallel data manipulation tasks more effectively. This makes the i7 a reasonable fit for file archiving, text processing, and database-style operations that do not rely heavily on floating-point or encryption.

The data shows a clear split: the Xeon 6315P excels in scenarios where single-core speed, floating-point precision, and cryptographic operations dominate, while the i7-8750H holds an advantage in parallel integer and data-shuffling workloads. The Xeon's 22.4% to 22.5% Cinebench multicore margins are modest compared to its single-thread and specialty wins, which suggests that the i7's additional threads narrow the gap in general multicore rendering but cannot overcome the Xeon's architecture in more specialized tasks.

Specification Differences

The Intel Xeon 6315P and Intel Core i7-8750H differ across nearly every fundamental specification. The Xeon has 4 cores and 4 threads, while the i7 has 6 cores and 12 threads. Base clocks are 2.80 GHz for the Xeon and 2.20 GHz for the i7, with boost clocks of 4.70 GHz and 4.10 GHz respectively. The Xeon has a TDP of 55 watts versus 45 watts for the i7.

The socket types are incompatible: the Xeon uses Intel Socket 1700, while the i7 uses Intel BGA 1440. The Xeon supports both DDR4 and DDR5 memory in a dual-channel configuration, while the i7 supports only DDR4. ECC memory is supported by the Xeon but not by the i7. The Xeon offers PCIe Gen 5 with 16 lanes (CPU only), while the i7 has no listed PCIe specification. The Xeon has no integrated graphics, whereas the i7 includes UHD 630 graphics.

The Xeon carries a launch MSRP of $213. The i7 has no recorded launch MSRP in the database. The Xeon is marked as Active production status and was released on 2025-02-23, while the i7 is End-of-life with a release date of 2018-04-01. The Xeon's part number is SRPLX, and the i7's is SR3YY. Neither processor has an unlocked multiplier.

Architecture Differences

The architectural gap between these two processors is significant. The Xeon 6315P is built on Raptor Lake architecture, specifically Raptor Lake-R, and belongs to the Xeon 6 generation (Raptor Lake Refresh). It uses a 10 nm process node fabricated by Intel. The i7-8750H, by contrast, is based on Coffee Lake architecture, specifically Coffee Lake-H, and belongs to the Core i7 generation. It uses a 14 nm process node.

The die sizes are similar but not identical: the Xeon measures 163 mm², while the i7 measures 149 mm². Cache layouts differ substantially. The Xeon has 80 KB of L1 cache per core and 1.25 MB of L2 cache per core, while the i7 has 64 KB of L1 per core and 256 KB of L2 per core. Both share 12 MB of L3 cache, but the Xeon's larger per-core L2 is notable given its lower core count.

The Xeon is aimed at the Server/Workstation market segment, while the i7 is a Mobile part. This is reflected in the Xeon's ECC support, DDR5 compatibility, and lack of integrated graphics. The i7 includes integrated UHD 630 graphics and is limited to DDR4 memory. The Xeon's PCIe Gen 5 support with 16 lanes is a clear generation leap over the i7, which has no listed PCIe specification. The process node difference, 10 nm versus 14 nm, partially explains the Xeon's higher clock speeds despite a higher core count in the i7. The Xeon's boost clock of 4.70 GHz versus 4.10 GHz for the i7, combined with a 55-watt TDP, indicates a more power-dense design tuned for single-thread performance and server-grade reliability features.
