AMD Ryzen 5 8645HS vs Intel Core i7-14701E Comparison

The AMD Ryzen 5 8645HS and Intel Core i7-14701E occupy the same performance tier, with average benchmark scores of 33244 and 33206 respectively — a razor-thin 0.1% gap. Yet beneath that statistical dead heat lies a dramatic divergence in workload behavior, architectural philosophy, and platform positioning. The data reveals a mobile Zen 4 chip that wins on specialized instruction efficiency while a desktop Raptor Lake part dominates raw throughput and single-thread speed.

Architecture Differences

The two CPUs come from fundamentally different design schools. AMD's Ryzen 5 8645HS is built on a 4 nm process at TSMC, packing 25,000 million transistors into a 178 mm² die. Intel's Core i7-14701E uses a 10 nm process at Intel's own foundry with a larger 257 mm² die. The AMD chip belongs to the Zen 4 architecture under the Hawk Point codename, while Intel runs Raptor Lake-R, part of the Raptor Lake Refresh generation.

Core counts differ significantly: Intel fields 8 cores and 16 threads against AMD's 6 cores and 12 threads. Cache hierarchies also diverge. Intel allocates 80 KB of L1 and 2 MB of L2 per core, plus a 33 MB shared L3. AMD provides 64 KB of L1 and 1 MB of L2 per core, with a 16 MB shared L3. Intel's larger L3 cache gives it a 33 MB total versus AMD's 16 MB.

Platform support tells a broader story. The AMD chip uses Socket FP8, targets mobile systems, and carries a 45 W TDP. Intel's part uses Socket 1700, is a desktop processor, and draws 65 W. Memory flexibility favors Intel with DDR4 and DDR5 support plus ECC; AMD only supports DDR5 without ECC. PCIe generations differ too — AMD offers Gen 4 with 20 CPU lanes, while Intel provides Gen 5 with 16 CPU lanes. Integrated graphics are Radeon 760M for AMD and UHD Graphics 770 for Intel. Both processors are locked (multiplier locked) and remain in active production.

Head-to-Head Benchmarks

The Intel Core i7-14701E wins 12 of 15 head-to-head tests, but the margins tell a nuanced story. In Cinebench R23 multi-core, Intel's victory is overwhelming: 22195 versus 13220, a 40.4% lead. The single-core R23 result is even starker — Intel scores 3133 against AMD's 1714, a 45.3% gap. Cinebench R15 shows a similar pattern, with Intel ahead 2237 to 2094 in multi-core (6.4%) and 315 to 270 in single-core (14.3%).

PassMark results amplify Intel's dominance in compute-heavy workloads. The find_prime_numbers test shows Intel at 176 versus AMD's 75, a 57.4% advantage — the largest delta in the entire benchmark suite. Physics testing follows closely: Intel scores 2399 against 1095, a 54.4% lead. Floating point math goes Intel's way at 61873 versus 44833 (27.5% ahead), and integer math favors Intel 81325 to 72640 (10.7%). The multithread test gives Intel 26112 against 22586 (13.5% ahead), while single-thread performance lands at 4305 versus 3653 (15.1% for Intel).

Yet AMD's three wins are concentrated and meaningful. Random string sorting goes to AMD with 31748 against Intel's 29158, an 8.9% edge. Extended instructions favor AMD at 20003 versus 18528, an 8% advantage. Data encryption rounds out AMD's wins at 15588 versus 14862, a 4.9% margin. Data compression is close — Intel wins 282939 to 265483, but only by 6.2%. The overall picture is clear: Intel dominates raw compute while AMD shows targeted strengths in specialized instruction handling and memory-access patterns.

Where Each One Wins

The Intel Core i7-14701E is the clear choice for any workload that scales with cores and raw clock speed. Its 40.4% Cinebench R23 multi-core lead and 45.3% single-core advantage make it the superior processor for rendering, video encoding, and general productivity where Cinebench-style performance matters. The 57.4% win in prime number finding and 54.4% lead in physics tests point to strengths in scientific computing and simulation workloads. For users running multithreaded applications, integer-heavy tasks, or floating-point math, Intel's 13.5% multithread, 10.7% integer, and 27.5% floating-point margins provide a substantial performance buffer.

The AMD Ryzen 5 8645HS carves out a different niche. Its wins in random string sorting (8.9% ahead) and extended instructions (8% ahead) suggest better efficiency in data parsing, sorting algorithms, and SIMD-style operations. The 4.9% data encryption edge indicates competitive security-focused workloads. For mobile users where the 45 W TDP versus Intel's 65 W matters, AMD's lower thermal envelope paired with its targeted performance wins could prove decisive. The data shows AMD is not universally slower — it simply wins in fewer, more specialized areas.

The Verdict

The benchmark data points to a straightforward conclusion: the Intel Core i7-14701E is the performance winner for most users. It wins 12 of 15 head-to-head tests, with particularly large margins in Cinebench R23 multi-core (40.4% ahead) and single-core (45.3% ahead). The Intel chip also offers greater core and thread counts, double the L3 cache (33 MB versus 16 MB), broader memory support including DDR4 and ECC, and a higher boost clock of 5.40 GHz. Its desktop platform and 65 W TDP support sustained performance in ways a mobile chip cannot match.

However, the AMD Ryzen 5 8645HS is not without merit. It delivers a 0.1% higher average benchmark score overall, despite losing most individual tests. Its wins in data encryption, extended instructions, and random string sorting show that certain workloads — particularly those involving cryptography, specialized instruction sets, and string manipulation — run more efficiently on Zen 4. The 4 nm process and smaller die size (178 mm² versus 257 mm²) suggest better power efficiency, supported by the 45 W TDP. For mobile users prioritizing battery life and portability, or for workloads specifically aligned with AMD's three benchmark wins, the Ryzen 5 8645HS presents a compelling case. For everyone else, the Intel Core i7-14701E's overwhelming compute performance makes it the data-backed choice.
