A: The Intel Core i7-14701TE has a 33 MB shared L3 cache, more than double the AMD Ryzen 7 7840U's 16 MB shared L3 cache. The AMD chip does have a smaller L2 cache per core at 1 MB versus the Intel's 2 MB per core.

Architecture Differences

The Intel Core i7-14701TE is built on Intel's Raptor Lake architecture, specifically the Raptor Lake-R refresh, using a 10 nm process node fabricated by Intel. It is a desktop part designed for Intel Socket 1700. The AMD Ryzen 7 7840U, in contrast, uses the Zen 4 architecture with the Phoenix codename, built on a 4 nm process at TSMC. It is a mobile processor using AMD Socket FP8. The process node difference is substantial: TSMC's 4 nm is a much denser process than Intel's 10 nm, which is reflected in the die sizes. The Intel chip has a die size of 257 mm², while the AMD chip measures 178 mm². The AMD chip also packs 25,000 million transistors into that smaller area.

Cache hierarchies differ notably. The Intel part offers 80 KB of L1 cache per core, 2 MB of L2 per core, and a 33 MB shared L3. The AMD part offers 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. This gives Intel a significant total cache advantage, which may explain its strong showing in Cinebench R23 multi-core where it leads by 33.9%.

Memory support also diverges. The Intel supports both DDR4 and DDR5, while the AMD supports only DDR5. Both use dual-channel memory buses. The AMD chip lists a memory bandwidth of 89.6 GB/s, while the Intel chip's bandwidth is not recorded. For PCIe, the Intel offers Gen 5 with 16 lanes (CPU only), whereas the AMD offers Gen 4 with 20 lanes (CPU only). The integrated graphics differ: Intel uses UHD Graphics 770, while AMD uses the Radeon 780M.

Clock speeds show a mixed picture. The AMD has a higher base clock at 3.30 GHz versus the Intel's 2.10 GHz, but the Intel has a higher boost clock at 5.20 GHz versus the AMD's 5.10 GHz. The Intel chip has a TDP of 45 watts, while the AMD is rated at 28 watts, indicating the AMD is designed for lower power envelopes typical of mobile parts. Both support ECC memory, and neither has an unlocked multiplier.

Head-to-Head Benchmarks

The head-to-head data reveals a processor pair that trades blows depending on the workload. The AMD Ryzen 7 7840U wins 11 of the 15 recorded head-to-head tests, while the Intel Core i7-14701TE wins 4. However, the margins tell a more nuanced story.

In Cinebench R15, the AMD wins both tests. In multi-core, it scores 1990 against the Intel's 1716, a 13.8% lead. In single-core, it scores 264 against 242, an 8.3% lead. These are moderate but clear wins for the AMD part in the older Cinebench version.

The tables turn dramatically in Cinebench R23. The Intel wins multi-core with 17035 versus 12719, a 33.9% advantage. In single-core, the Intel wins with 2405 versus 1677.5, a 43.4% lead. This is a remarkable reversal from R15 and suggests that the R23 workload is far more favorable to the Intel architecture, possibly due to its larger cache or higher boost clock.

PassMark results favor the AMD heavily. In data compression, the AMD scores 288604 against 220520, a 23.6% lead. Data encryption shows the AMD at 17691 versus 11699, a 33.9% win. Extended instructions go to the AMD 20432 versus 14354, a 29.7% margin. Integer math favors the AMD 90852 versus 65792, a 27.6% lead. Random string sorting goes to the AMD 33757 versus 22760, a 32.6% margin. Floating point math is close, with the AMD winning 51767 versus 50219, only a 3% difference. PassMark multi-thread goes to the AMD 24782 versus 20042, a 19.1% lead. PassMark single-thread goes to the AMD 3565 versus 2637, a 26% advantage.

The Intel's PassMark wins are narrower in count but large in margin. It wins find prime numbers 143 versus 80, a 78.8% lead, and physics 1860 versus 1256, a 48.1% lead. These are the two largest single-test margins in the entire comparison, both going to the Intel.

The Cinebench R23 results for the Intel are its strongest multi-threaded statement. The 33.9% lead in multi-core over the AMD is a substantial gap. Yet the AMD counters with equally decisive wins across most PassMark categories. The data suggests that the Intel chip excels in specific computational patterns, particularly prime number finding and physics simulations, while the AMD dominates general-purpose integer and encryption workloads.

The Verdict

The benchmark data paints a clear but split picture. The AMD Ryzen 7 7840U wins the majority of head-to-head tests, 11 out of 15, and its wins are spread across many PassMark categories including data compression, encryption, integer math, and single-thread performance. The Intel Core i7-14701TE wins only 4 tests, but two of those wins are by massive margins: 78.8% in find prime numbers and 48.1% in physics. It also wins both Cinebench R23 tests by large margins of 33.9% and 43.4%.

For users whose workloads align with Cinebench R23, the Intel is the clear choice. The 17035 multi-core score is a strong result, and the 2405 single-core score suggests excellent responsiveness in lightly threaded tasks within that benchmark's framework. The Intel's 5.20 GHz boost clock likely contributes to this advantage.

For users whose workloads resemble PassMark's suite, the AMD is the better pick. Its wins in data compression, encryption, extended instructions, integer math, random string sorting, and single-thread all exceed 23%, and it wins multi-thread by 19.1%. The AMD also does this at a 28 watt TDP, which is significantly lower than the Intel's 45 watt TDP, making it a more power-efficient option for sustained workloads in mobile or compact systems.

The overall average benchmark scores are close, with the Intel at 26013 and the AMD at 25432, a difference of about 2.3% in the Intel's favor. The percentile rankings are similarly close at 78 versus 77. This near-parity in overall scores masks the very different workload-specific results. The decision should hinge on which benchmark family best represents the intended use case.
