AMD Ryzen 5 40 vs Intel Core i7-14701E Comparison

The AMD Ryzen 5 40 and Intel Core i7-14701E occupy different corners of the processor market, and the benchmark data reflects that divide clearly. The Ryzen 5 40 is a low-power mobile chip built on AMD’s Zen 2 architecture, while the Core i7-14701E is a desktop part from Intel’s Raptor Lake Refresh family. Across every recorded benchmark, the Intel processor posts a higher score, with the margin ranging from moderate to overwhelming. The data shows a consistent pattern: the Core i7-14701E leads in all 15 head-to-head comparisons, while the Ryzen 5 40 records zero wins. That does not make the AMD part irrelevant, as its design goals differ fundamentally, but the performance gap is unambiguous.

Head-to-Head Benchmarks

The largest single margin appears in the Cinebench R23 multi-core test. The Intel Core i7-14701E scores 22195, while the AMD Ryzen 5 40 scores 4841, a difference of 78.2% in favor of Intel. This is not a close contest by any measure. The Cinebench R15 multi-core test tells a similar story: Intel scores 2237, AMD scores 790, a 64.7% gap. These multi-threaded workloads rely heavily on core count and sustained power delivery, both of which favor the Intel part’s 8 cores and 16 threads over the AMD part’s 4 cores and 8 threads.

Single-core performance shows a narrower but still decisive gap. In Cinebench R23 single-core, the Intel chip scores 3133 against 1150 for AMD, a 63.3% difference. Cinebench R15 single-core sees Intel at 315 and AMD at 165.5, a 47.5% gap. The PassMark single-thread test repeats the pattern: Intel scores 4305, AMD scores 2477, a 42.5% difference. The Intel processor’s higher boost clock of 5.40 GHz, compared to 4.30 GHz for the AMD chip, likely explains much of this advantage, though the architectural differences also play a role.

The PassMark suite provides additional detail. In integer math, Intel scores 81325 against AMD’s 31598, a 61.1% lead. Floating-point math shows an even larger gap: 61873 for Intel versus 15194 for AMD, a 75.4% difference. Data compression follows with Intel at 282939 and AMD at 141533, a 50% gap. Data encryption sees Intel at 14862 and AMD at 6646, a 55.3% difference. Extended instructions, which test SIMD and other advanced operations, show Intel at 18528 and AMD at 6437, a 65.3% gap.

The remaining PassMark tests follow suit. Find prime numbers, a heavily integer-bound workload, shows Intel at 176 and AMD at 20, an 88.6% difference, the largest proportional gap in the entire dataset. Physics simulation scores 2399 for Intel and 432 for AMD, an 82% difference. Random string sorting sees Intel at 29158 and AMD at 15124, a 48.1% gap. The multithread score, which aggregates several workloads, shows Intel at 26112 and AMD at 9341, a 64.2% difference. Across every test, the Intel Core i7-14701E delivers at least 42.5% higher performance, with most margins exceeding 50%.

Architecture Differences

The two processors diverge at almost every level of their design. The AMD Ryzen 5 40 uses the Zen 2 architecture with the Mendocino codename, built on a 6 nm process at TSMC. The Intel Core i7-14701E uses the Raptor Lake architecture with the Raptor Lake-R codename, fabricated on Intel’s 10 nm process. The process node difference is notable, as the AMD chip’s smaller node allows for lower power consumption, but the Intel chip’s larger die, 257 mm² versus 100 mm², accommodates more transistors and more functional blocks.

Core counts differ substantially. The AMD part has 4 cores and 8 threads, while the Intel part has 8 cores and 16 threads. This doubling of cores and threads directly explains the multi-core benchmark results. Cache hierarchies also differ. The AMD chip has 64 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The Intel chip has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Intel part’s L3 cache is more than eight times larger, which helps with data reuse in larger working sets.

Memory support diverges as well. The AMD Ryzen 5 40 supports LPDDR5 memory with a dual-channel bus and a measured bandwidth of 88.0 GB/s. The Intel Core i7-14701E supports both DDR4 and DDR5, also with a dual-channel bus, though the database does not list a bandwidth figure for it. The Intel chip also supports ECC memory, while the AMD chip does not. PCIe connectivity differs sharply: the AMD part offers Gen 3 with 4 lanes from the CPU, while the Intel part offers Gen 5 with 16 lanes. This makes the Intel chip far more suitable for high-bandwidth expansion cards and storage.

Integrated graphics also differ. The AMD chip uses the Radeon 610M, while the Intel chip uses UHD Graphics 770. The database does not provide benchmark scores for either iGPU, so a direct comparison is not possible from the recorded data. The market segments separate them further: the AMD part is classified as Mobile, while the Intel part is Desktop. The AMD chip’s TDP of 15 W versus the Intel chip’s 65 W reinforces this split, as does the socket: AMD Socket FT6 for the mobile chip, Intel Socket 1700 for the desktop chip.

Where Each One Wins

The benchmark data shows no test where the AMD Ryzen 5 40 outperforms the Intel Core i7-14701E. However, the context matters. The AMD chip is designed for mobile devices where power draw is a primary constraint. Its 15 W TDP, compared to 65 W for the Intel part, suggests it can operate in thin-and-light laptops with limited cooling. The Intel chip, by contrast, requires a desktop platform with more substantial cooling and power delivery. The database does not include efficiency metrics like performance-per-watt, so those conclusions remain qualitative, but the TDP figures are recorded.

For single-threaded tasks, the Intel chip’s 5.40 GHz boost clock and higher single-core scores make it the better choice for applications that rely on one or two threads, such as lightweight productivity or older software. The 42.5% lead in PassMark single-thread performance confirms this. For multi-threaded workloads like video encoding, 3D rendering, or compilation, the Intel chip’s 8 cores and 16 threads, combined with its larger L3 cache, produce a 64.2% to 78.2% advantage in the Cinebench and PassMark multi-core tests. The Intel part also wins decisively in memory-sensitive workloads like data compression, where its 33 MB L3 cache likely helps sustain higher throughput.

The AMD chip’s strengths lie outside raw performance. Its 6 nm process and 15 W TDP indicate a focus on energy efficiency, which the database confirms through the power figures. Its LPDDR5 support suggests it pairs with low-power memory in compact devices. The Radeon 610M integrated graphics may provide adequate display output for basic tasks, though no comparative iGPU data exists in the database. The AMD chip’s smaller die size, 100 mm² versus 257 mm², also hints at lower manufacturing cost per wafer, though pricing data is not available.

The Verdict

The data points to a clear conclusion for raw performance: the Intel Core i7-14701E dominates the AMD Ryzen 5 40 in every measured workload. The 8-core, 16-thread configuration, higher boost clock, larger cache, and broader PCIe support combine to produce leads of 42.5% to 88.6% across the benchmark suite. Users who need multi-core throughput for rendering, simulation, or compilation should favor the Intel chip without hesitation. Its 33 MB L3 cache and 5.40 GHz boost clock also serve single-threaded tasks well, as the 63.3% Cinebench R23 single-core lead demonstrates.

The AMD Ryzen 5 40 serves a different purpose. Its 15 W TDP, LPDDR5 memory support, and mobile classification indicate a design optimized for battery-powered devices where performance takes a back seat to efficiency. The 6 nm process and smaller die size further confirm this focus. For a thin laptop needing basic productivity and long battery life, the AMD chip may be the sensible choice, though the database does not include battery or efficiency benchmarks to quantify that trade-off. The Intel chip’s 65 W TDP and Desktop segment make it unsuitable for such use, while the AMD chip’s 4 cores and 8 threads would struggle in the multi-threaded workloads where the Intel chip excels.

The percentile rankings reinforce the gap. The Intel Core i7-14701E sits in the 83rd percentile of all CPUs, while the AMD Ryzen 5 40 sits in the 70th percentile. The average benchmark score for Intel is 33206, more than double the AMD chip’s 15882. These figures place the Intel chip alongside competitors like the AMD Ryzen 9 PRO 6950H and Intel Core i7-13650HX, while the AMD chip’s nearest rivals include server parts like the AMD EPYC 75F3 and EPYC 9354P, indicating a different performance class entirely. The choice between these two processors depends on the platform: mobile efficiency from AMD, desktop performance from Intel.
