Architecture Differences

The Intel Core i7-14701E is built on Intel’s Raptor Lake architecture, specifically the Raptor Lake-R refresh die, using a 10 nm process at Intel’s own foundry. The die measures 257 mm². The AMD Ryzen 5 PRO 7645 uses TSMC’s 5 nm process for the Zen 4 Raphael architecture, with a much smaller 71 mm² die and a transistor count of 6,570 million. This process and die size disparity reflects fundamentally different design philosophies: Intel uses a larger, higher-power envelope to fit more x86 cores, while AMD relies on a denser, more efficient process node.

Cache hierarchies differ in both capacity and placement. The Intel part offers 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The AMD part has 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. The Intel L3 is marginally larger, but the per-core L2 advantage (2 MB versus 1 MB) is more significant for workloads that fit in that tier. Neither processor features 3D V-Cache.

Memory support diverges sharply. The Intel chip supports both DDR4 and DDR5, while the AMD chip supports only DDR5. Both use dual-channel memory buses, but the database lists an explicit 83.2 GB/s memory bandwidth figure for the AMD part only. ECC memory is supported on both processors, which is notable for workstation and server use.

PCIe lane counts also differ. The Intel i7-14701E provides Gen 5 with 16 CPU lanes, while the AMD Ryzen 5 PRO 7645 provides Gen 5 with 24 CPU lanes. This gives the AMD platform more headroom for expansion cards, NVMe drives, or other Gen 5 devices directly attached to the CPU.

Integrated graphics differ as well. The Intel part includes UHD Graphics 770, while the AMD part includes Radeon Graphics. Neither is a discrete-class GPU, but the presence of any iGPU means both can drive displays without an add-in card.

The market segments differ in the database: the Intel chip is listed as Desktop, while the AMD chip is listed as Server/Workstation. This aligns with the AMD part’s ECC support and higher PCIe lane count, making it more suitable for memory-intensive or I/O-heavy server tasks despite its lower core count.

The release dates are about a year apart. The AMD Ryzen 5 PRO 7645 launched in June 2023, while the Intel Core i7-14701E launched in June 2024. Both remain in active production.

Head-to-Head Benchmarks

The head-to-head data shows 12 wins for the Intel Core i7-14701E and 5 wins for the AMD Ryzen 5 PRO 7645 across 17 recorded tests. The Intel part wins every Cinebench test by a consistent 2.2% to 2.3% margin, indicating a stable per-clock advantage in rendering workloads. Specifically, Cinebench R15 multi-core scores 2237 versus 2188, R15 single-core scores 315 versus 308, R20 multi-core scores 9321 versus 9118, R20 single-core scores 1315 versus 1287, R23 multi-core scores 22195 versus 21710, and R23 single-core scores 3133 versus 3065.

The Intel part’s largest win comes in PassMark physics, where it scores 2399 versus 1598, a 50.1% advantage. This is the single biggest delta in the entire comparison. Floating point math also heavily favors Intel, with a score of 61873 versus 45202, a 36.9% lead. Integer math goes to Intel with 81325 versus 74782, an 8.7% lead. PassMark multithread shows Intel ahead with 26112 versus 25489, a 2.4% margin, and single-thread tests show Intel at 4305 versus 3652, a 17.9% advantage. The two single-thread PassMark tests are identical in score, confirming the result.

The AMD Ryzen 5 PRO 7645 takes the remaining five tests, all in PassMark sub-tests. Random string sorting is its biggest win, 34557 versus 29158, a 15.6% lead. Extended instructions follow with 21813 versus 18528, a 15.1% lead. Find prime numbers goes to AMD at 198 versus 176, an 11.1% lead. Data encryption shows AMD ahead at 16657 versus 14862, a 10.8% lead. Data compression is the narrowest AMD win, 286298 versus 282939, just 1.2% ahead.

This split paints a clear picture: Intel dominates in physics simulation, floating point math, and single-thread integer performance, while AMD counters in string sorting, encryption, and vectorized instruction throughput. The Intel part’s core count advantage (8 versus 6) helps in multi-threaded rendering, but AMD’s Zen 4 architecture is strong in memory-latency-sensitive and instruction-level parallel workloads.

Specification Differences

The two processors differ in several key specification fields. The Intel Core i7-14701E has 8 cores and 16 threads, while the AMD Ryzen 5 PRO 7645 has 6 cores and 12 threads. Base clocks differ: Intel runs at 2.60 GHz, AMD at 3.80 GHz. Boost clocks also differ: Intel reaches 5.40 GHz, AMD reaches 5.10 GHz. The TDP is identical at 65 W for both.

Process nodes differ: Intel uses 10 nm, AMD uses 5 nm. The Intel die is 257 mm², AMD’s is 71 mm². Transistor count is listed only for AMD at 6,570 million. Cache sizes differ across all levels: L1 per core is 80 KB for Intel versus 64 KB for AMD; L2 per core is 2 MB for Intel versus 1 MB for AMD; L3 shared is 33 MB for Intel versus 32 MB for AMD.

Memory support differs: Intel supports DDR4 and DDR5, AMD supports only DDR5. Memory bandwidth is listed only for AMD at 83.2 GB/s. PCIe lanes differ: Intel has Gen 5 with 16 lanes, AMD has Gen 5 with 24 lanes. Integrated graphics differ: Intel has UHD Graphics 770, AMD has Radeon Graphics. Market segment differs: Intel is Desktop, AMD is Server/Workstation. Release dates differ: Intel launched in June 2024, AMD in June 2023. Socket types differ: Intel uses Socket 1700, AMD uses Socket AM5. Part numbers also differ: Intel is Q49FSRNJK, AMD is 100-000000600.

The Verdict

The data supports a clear split recommendation based on workload type. For users running Cinebench rendering, physics simulation, or floating point math, the Intel Core i7-14701E is the stronger choice. It wins all six Cinebench tests by 2.2% to 2.3%, and its 50.1% lead in PassMark physics is decisive. Single-thread performance also favors Intel by 17.9% in PassMark, making it the better pick for lightly threaded applications that rely on high boost clocks.

For users handling data encryption, string sorting, or extended instruction workloads, the AMD Ryzen 5 PRO 7645 delivers meaningful wins. It leads by 10.8% in encryption, 15.1% in extended instructions, and 15.6% in random string sorting. These are not trivial margins, and they indicate that the Zen 4 architecture handles certain instruction-level parallel tasks more efficiently despite having fewer cores.

The AMD part also offers more PCIe lanes (24 versus 16) and a smaller, more power-dense die on a more advanced 5 nm process. This makes it a better fit for server or workstation environments that need I/O expansion. The Intel part counters with a larger L3 cache and per-core L2 cache, plus support for both DDR4 and DDR5 memory, which may ease platform migration for existing Intel users.

The overall win count is 12 to 5 in favor of Intel, and the average benchmark score is higher for Intel (33206 versus 32446). However, the AMD part’s wins are concentrated in specific, repeatable workloads, not random noise. Users who know their primary applications fall into the AMD-favored categories should not be swayed by the overall score alone. Conversely, users with mixed workloads will likely benefit more from the Intel part’s broad dominance in rendering and physics.

Both processors sit at the 83rd percentile, meaning they are in the same performance tier overall. The choice comes down to whether the user prioritizes the Intel part’s multi-core rendering and physics strengths or the AMD part’s encryption, string sorting, and instruction-level advantages. With identical 65 W TDPs, power consumption is not a differentiating factor in the recorded data. The absence of unlocked multipliers on both parts means overclocking headroom is not a selling point for either.

In summary, the Intel Core i7-14701E is the recommended pick for general desktop workloads, creative rendering, and physics-heavy simulation. The AMD Ryzen 5 PRO 7645 is the recommended pick for server-side tasks involving encryption, data sorting, and extended instruction processing, especially where the extra PCIe lanes are valuable.
