AMD's nearest rival, the Xeon w5-3525, scores 67673, putting the EPYC 4465P 1.1% behind it; the Core Ultra 5 250K Plus scores 66855, with AMD 0.1% ahead. The data shows a clear split: Intel for desktop compute, AMD for server efficiency.

Architecture Differences

The two processors come from different foundries and process nodes. Intel uses its own 10nm process for the Raptor Lake architecture, while AMD uses TSMC's 4nm process for the Zen 5 architecture, codenamed Grado. Intel's die is 257 mm²; AMD's is two dies of 70.6 mm² each, with 16,630 million transistors. Intel's generation is listed as Core i7 (Raptor Lake Refresh), and AMD's as EPYC (Zen 5 (Grado)). Both parts are listed as Active in production status.

Core counts differ substantially. Intel provides 20 cores and 28 threads, while AMD provides 12 cores and 24 threads. Base clocks are identical at 3.40 GHz, but Intel boosts to 5.60 GHz versus AMD's 5.40 GHz. TDP is a major differentiator: Intel draws 125W, AMD only 65W. Cache layouts also diverge. Both have 80 KB of L1 per core. Intel has 2 MB of L2 per core and 33 MB of shared L3; AMD has 1 MB of L2 per core and 64 MB of shared L3.

Memory support differs as well. Intel supports both DDR4 and DDR5 in a dual-channel configuration, while AMD supports only DDR5, also dual-channel, with a recorded memory bandwidth of 89.6 GB/s. Both support ECC memory. PCIe connectivity favors AMD: Gen 5 with 24 lanes from the CPU, versus Intel's Gen 5 with 16 lanes. AMD also includes integrated Radeon Graphics, while Intel has no integrated graphics. The sockets are incompatible: Intel uses Socket 1700, AMD uses AM5. Intel's multiplier is unlocked; AMD's is locked. Release dates are 2023-10-16 for Intel and 2025-05-12 for AMD, and the market segments are Desktop for Intel and Server/Workstation for AMD. The part numbers are SRN3Y for Intel and 100-000001558 for AMD.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent Intel advantage. In R15 multi-core, Intel scores 4452 against AMD's 4326, a 2.9% lead. R15 single-core is 628 vs 610, a 3% lead. R20 multi-core is 18550 vs 18025, 2.9%; R20 single-core is 2618 vs 2544, 2.9%. R23 multi-core is 44167 vs 42918, 2.9%; R23 single-core is 6235 vs 6059, 2.9%. The margins are nearly uniform, suggesting a stable architectural edge in this workload. Notably, the single-core margins match the multi-core margins almost exactly, which points to a per-thread advantage rather than a core-count effect.

The Passmark suite reveals larger swings. Intel's biggest wins come in data encryption, where it scores 40046 against 32184, a 24.4% margin, and floating-point math, 134393 vs 105833, a 27% margin. Data compression goes to Intel at 694963 vs 577210, a 20.4% margin. Random string sorting favors Intel at 74723 vs 67597, a 10.5% margin. Multithread is 52425 vs 49871, a 5.1% margin, and integer math is 183056 vs 174551, a 4.9% margin. These wins are spread across memory-heavy and compute-heavy tasks, giving Intel a broad lead in general-purpose throughput.

AMD's wins are concentrated in specific workloads. Find prime numbers is the largest: 338 vs 212, a 37.3% margin for AMD. Physics goes to AMD at 3647 vs 2961, an 18.8% margin. Extended instructions, a Passmark test category, favor AMD at 42867 vs 40660, a 5.1% margin. Single-thread Passmark is 4575 vs 4480, a 2.1% margin for AMD. The single-thread test appears twice in the database with identical scores, so it counts as two wins in the overall tally. The pattern is clear: AMD wins where the workload is narrow and specialized, while Intel wins where the workload is broad and parallel.

Where Each One Wins

The Intel Core i7-14700KF wins in rendering and content-creation workloads. Every Cinebench test, from R15 to R23, single-core and multi-core, goes to Intel with margins of 2.9% to 3%. It also dominates data compression and encryption, with margins of 20.4% and 24.4% respectively, making it the stronger choice for file archiving, database workloads, and encrypted storage. Floating-point math is a 27% win, integer math a 4.9% win, and multithread a 5.1% win. Random string sorting, a proxy for sorting algorithms, goes to Intel by 10.5%. For a desktop user running Cinebench, compression tools, or math-heavy applications, the data points squarely at Intel. The unlocked multiplier and support for both DDR4 and DDR5 add flexibility for desktop builders.

The AMD EPYC 4465P wins in server-oriented and efficiency-sensitive scenarios. Its 37.3% margin in find prime numbers indicates a strong integer prime-search capability, useful in workloads that stress prime number generation. Physics simulation goes to AMD by 18.8%. Extended instructions favor AMD by 5.1%. Single-thread Passmark goes to AMD by 2.1%, so lightly threaded tasks see a small AMD edge. The 65W TDP, 64MB L3 cache, 24 PCIe Gen 5 lanes, and integrated Radeon Graphics make it the better fit for a workstation or server chassis where power, cache capacity, and I/O expansion matter. The data shows a clean split: Intel for desktop compute throughput, AMD for server efficiency and specialized instruction workloads.
