Intel Core i7-9750H vs Intel Xeon 6315P Comparison

The Intel Core i7-9750H and Intel Xeon 6315P represent fundamentally different design philosophies, despite both being Intel parts. The i7-9750H is a 6-core, 12-thread mobile processor from the Coffee Lake-HR generation, built on a 14 nm node, while the Xeon 6315P is a 4-core, 4-thread server/workstation chip from the Raptor Lake Refresh generation, built on a 10 nm node. The benchmark data reveals a stark split: the Xeon wins 14 of 17 head-to-head tests, but the i7-9750H secures decisive victories in specific workloads. Both processors sit at the 69th percentile among all CPUs, with the i7-9750H averaging a score of 14886 and the Xeon 6315P averaging 14574. This near-parity in overall standing makes the individual benchmark deltas all the more telling.

Where Each One Wins

The Intel Xeon 6315P dominates the overwhelming majority of compute benchmarks, winning every Cinebench test across R15, R20, and R23, in both single-core and multi-core variants. Its lead is consistent, ranging from 11.5% to 11.8% across all Cinebench tests. For instance, in Cinebench R23 multi-core, the Xeon scores 10134 against the i7-9750H's 8973, a delta of -11.5% from the i7's perspective. The Xeon also takes PassMark's floating-point math (33496 vs 23343, a 30.3% advantage), extended instructions (10539 vs 9187, a 12.8% advantage), and physics (1156 vs 670, a 42% advantage). Its single-thread PassMark score of 3795 is 36.7% higher than the i7-9750H's 2404, showcasing a massive per-core performance gap.

The Intel Core i7-9750H, however, wins in three specific PassMark sub-tests, all of which involve memory or parallel integer workloads. Its most significant victory is in integer math, where it scores 37822 against the Xeon's 27046, a 39.8% advantage. It also wins in data compression (150443 vs 118313, a 27.2% edge) and random string sorting (19862 vs 14487, a 37.1% advantage). These wins are not marginal; they are substantial, suggesting that the i7-9750H's higher core count and thread count provide a decisive edge in workloads that scale well with parallel integer operations. The data shows a clear trade-off: the Xeon excels at single-threaded and floating-point tasks, while the i7-9750H dominates in multi-threaded integer-heavy processing.

Architecture Differences

The architectural divide between these two processors explains the benchmark results. The i7-9750H features 6 cores and 12 threads, with a base clock of 2.60 GHz and a boost clock of 4.50 GHz. It is built on Intel's 14 nm process with a die size of 149 mm² and belongs to the Coffee Lake-HR generation. Its cache hierarchy includes 64 KB of L1 per core, 256 KB of L2 per core, and 12 MB of shared L3 cache. The processor supports dual-channel DDR4 memory with a bandwidth of 42.7 GB/s and does not support ECC memory. It integrates UHD 630 graphics and uses PCIe Gen 3 connectivity, targeting the mobile market segment.

The Xeon 6315P, by contrast, offers only 4 cores and 4 threads, with no hyper-threading. Its base clock is 2.80 GHz, boosting to 4.70 GHz, which is higher than the i7-9750H's max boost. It is fabricated on a 10 nm node with a larger die size of 163 mm², belonging to the Raptor Lake Refresh generation. Its caches are substantially larger per core: 80 KB of L1 per core and 1.25 MB of L2 per core, though it shares the same 12 MB of L3 cache. The Xeon supports both DDR4 and DDR5 memory (dual-channel), includes ECC memory support, and offers PCIe Gen 5 with 16 lanes (CPU only). It has no integrated graphics and is aimed at the server/workstation segment. The combination of a newer process node, higher clocks, and larger per-core caches gives the Xeon a significant single-threaded advantage, which is reflected in its 36.7% higher PassMark single-thread score.

The Verdict

Based strictly on the data, the Intel Xeon 6315P is the superior processor for most compute-intensive tasks. It wins every Cinebench test, dominating in both single-core and multi-core rendering scenarios. Its 11.5% lead in Cinebench R23 multi-core (10134 vs 8973) is notable, given that the i7-9750H has 50% more cores and 200% more threads. The Xeon's edge in floating-point math (30.3%), physics (42%), and extended instructions (12.8%) further cements its position as the better choice for scientific, engineering, and simulation workloads. For users prioritizing raw single-thread performance or floating-point throughput, the Xeon 6315P is the clear winner, with its PassMark single-thread score of 3795 dwarfing the i7-9750H's 2404.

The Intel Core i7-9750H is the better option only in specific integer-heavy, multi-threaded scenarios. Its 39.8% lead in integer math, 27.2% advantage in data compression, and 37.1% edge in random string sorting indicate that it can outperform the Xeon in tasks like database operations, file compression, and certain cryptographic workloads that leverage parallel integer execution. However, these wins are narrow in scope compared to the Xeon's broad dominance across rendering, physics, and single-threaded tasks. The i7-9750H's 6-core/12-thread configuration gives it a niche, but the Xeon's newer architecture and higher per-core efficiency make it the more versatile choice for most professional applications. The Xeon 6315P is the recommended part for general workstation use, while the i7-9750H suits workloads specifically optimized for high thread counts and integer math.

Head-to-Head Benchmarks

The head-to-head data reveals a pattern of consistent Xeon superiority in most tests, punctuated by three significant i7-9750H victories. Starting with the Cinebench suite, the Xeon 6315P wins all six tests with nearly identical deltas. In Cinebench R15, the Xeon scores 1021 multi-core and 144 single-core, against the i7-9750H's 904 and 127, respectively, both showing an 11.5% and 11.8% delta. This pattern holds for Cinebench R20 (4256 vs 3768 multi-core; 600 vs 531 single-core) and Cinebench R23 (10134 vs 8973 multi-core; 1430 vs 1266 single-core), with the delta consistently at -11.5% for multi-core and -11.5% for single-core in the later tests. The consistency of these margins indicates a fundamental per-core performance advantage for the Xeon, which cannot be overcome by the i7-9750H's additional cores in these rendering workloads.

The PassMark results tell a more nuanced story. The Xeon wins in data encryption (5470 vs 3756, a 31.3% edge), extended instructions (10539 vs 9187, 12.8%), find prime numbers (150 vs 32, a massive 78.7% delta), floating-point math (33496 vs 23343, 30.3%), multithread (11923 vs 10671, 10.5%), physics (1156 vs 670, 42%), and single-thread (3795 vs 2404, 36.7%). The find prime numbers result is particularly stark, with the Xeon scoring 150 to the i7-9750H's 32, highlighting an extreme advantage in this specific integer-heavy, latency-sensitive workload. However, the i7-9750H fights back in data compression, scoring 150443 vs the Xeon's 118313, a 27.2% win, and in random string sorting, with 19862 vs 14487, a 37.1% margin. Its largest win comes in integer math, where it scores 37822 against the Xeon's 27046, a 39.8% advantage. These three wins suggest that the i7-9750H's 12 threads provide a tangible benefit in parallel integer operations, but they are insufficient to offset the Xeon's dominance in the broader benchmark suite, where the Xeon claims 14 of 17 total wins.
