Intel Core i7-14700KF vs Intel Xeon 6515P Comparison

The Verdict

The Intel Core i7-14700KF and Intel Xeon 6515P target fundamentally different environments, and the benchmark data reflects that split. The i7-14700KF wins 14 of the 17 recorded head-to-head tests, with decisive margins in Cinebench R15, R20, and R23 across both multicore and singlecore loads, all at exactly a 14.6% delta. It also leads in PassMark integer math by 24.5%, data compression by 17.3%, multithread by 15.6%, random string sorting by 16%, floating point math by 4.2%, and data encryption by 31.4%. The Xeon 6515P takes only 3 wins: extended instructions, find prime numbers, and physics, with deltas of -23.8%, -44.9%, and -22.7% respectively. The PassMark single-thread result is especially lopsided: 4480 for the i7 versus 2855 for the Xeon, a 56.9% lead.

For desktop users, content creators, and anyone running heavily threaded productivity workloads with single-thread responsiveness, the i7-14700KF is the clear choice from the recorded data. For server racks, memory-bandwidth-bound workloads, or applications that lean on extended instruction sets and prime-number math, the Xeon 6515P shows targeted strengths but lags elsewhere. The average benchmark scores put the i7 at 70163 versus 67006 for the Xeon, with percentiles of 94 versus 93 against all CPUs. The i7 also sits 0.2% above the AMD Ryzen 7 9700F and 0.4% above the AMD Ryzen 9 7940HX, while the Xeon is 0.1% ahead of the AMD EPYC 4465P and 0.2% ahead of the Intel Core Ultra 5 250K Plus. Neither processor dominates its rival cluster by much, but the i7 edges out a higher percentile ranking.

Architecture Differences

The i7-14700KF uses Raptor Lake architecture, specifically the Raptor Lake-R codename, built on Intel's 10 nm process with a die size of 257 mm². It has 20 cores and 28 threads, a base clock of 3.40 GHz, a boost clock of 5.60 GHz, and a TDP of 125 W. The cache layout is 80 KB L1 per core, 2 MB L2 per core, and 33 MB shared L3. Memory support includes both DDR4 and DDR5 in dual-channel configuration, with ECC memory supported. The PCIe implementation is Gen 5 with 16 lanes from the CPU only. It is an unlocked multiplier part (part number SRN3Y), fits the Intel Socket 1700, and launched on 2023-10-16 with a launch MSRP of $384.

The Xeon 6515P uses Granite Rapids architecture, with the same Granite Rapids codename, built on Intel's 5 nm process. It has 16 cores and 32 threads, a base clock of 2.30 GHz, a boost clock of 3.80 GHz, and a TDP of 150 W. The cache layout is 112 KB L1 per core, 2 MB L2 per core, and 72 MB shared L3. Memory support is DDR5 only, but over an eight-channel bus with a recorded memory bandwidth of 409.6 GB/s. PCIe is Gen 5 with 88 lanes from the CPU only. The multiplier is locked (part number SRVU6), it uses the Intel Socket 4710, and it launched on 2025-02-23 with a launch MSRP of $740. There is no integrated graphics on the Xeon, while the i7's integrated graphics field is not recorded.

The process difference is notable: 10 nm for the i7 versus 5 nm for the Xeon. The Xeon's per-core L1 is larger (112 KB versus 80 KB), and its L3 is more than double (72 MB versus 33 MB). The Xeon also offers 88 PCIe lanes versus 16, and an eight-channel memory bus versus dual-channel, which explains the massive bandwidth figure. The i7 counters with higher clocks on both base and boost, plus more cores and a lower TDP. The i7 also has 28 threads to the Xeon's 32, meaning the Xeon extracts more threads per core, but the i7's core count advantage (20 versus 16) gives it more total execution units.

Head-to-Head Benchmarks

Cinebench results are uniform: the i7-14700KF wins every R15, R20, and R23 test, both multicore and singlecore, with the same 14.6% delta in each case. The multicore scores are 4452 versus 3885 in R15, 18550 versus 16189 in R20, and 44167 versus 38547 in R23. Singlecore scores are 628 versus 548, 2618 versus 2285, and 6235 versus 5442. This consistency suggests the i7's clock advantage and core count translate directly across Cinebench's scaling.

PassMark results are more mixed. The i7 leads in multithread (52425 versus 45350, a 15.6% delta), integer math (183056 versus 147047, 24.5%), data compression (694963 versus 592645, 17.3%), data encryption (40046 versus 30476, 31.4%), random string sorting (74723 versus 64425, 16%), and floating point math (134393 versus 128954, 4.2%). The i7 also wins single-thread with 4480 versus 2855, a 56.9% advantage that is the largest delta in the entire comparison.

The Xeon's three wins are telling. Extended instructions: 53383 versus 40660, a 23.8% lead for the Xeon. Find prime numbers: 385 versus 212, a 44.9% lead. Physics: 3829 versus 2961, a 22.7% lead. These are workloads that often benefit from larger caches, wider memory buses, or different instruction scheduling. The Xeon's 72 MB L3 and eight-channel DDR5 at 409.6 GB/s likely contribute to the prime-number and physics results, while its extended instruction score suggests a more capable SIMD pipeline for that specific test.

The overall winner count is 14 for the i7 versus 3 for the Xeon. But the magnitude matters: the i7's wins range from 4.2% to 56.9%, while the Xeon's wins range from 22.7% to 44.9%. The Xeon is not merely competitive in its three categories; it leads substantially. Still, the i7's single-thread dominance and broad multicore superiority make it the better all-round performer in the recorded data.
