AMD Ryzen 9 7940HX vs Intel Core i7-14700 Comparison

The Intel Core i7-14700 and AMD Ryzen 9 7940HX occupy nearly the same performance tier, with the AMD part holding a slight edge in average benchmark score (60,695 vs. 59,621) and both sitting at the 95th percentile of all CPUs. However, they are fundamentally different products: the i7-14700 is a desktop processor built on Intel’s Raptor Lake architecture, while the 7940HX is a mobile flagship from AMD’s Zen 4 Dragon Range family. The data reveals a consistent pattern—the AMD chip wins the overwhelming majority of head-to-head tests, often by substantial margins, while the Intel part counters with a single-threaded Passmark victory and a lower launch MSRP. This analysis breaks down the architecture, specifications, and benchmark results to clarify which processor fits which use case.

FAQ

A: The Intel Core i7-14700 has 20 cores and 28 threads, while the AMD Ryzen 9 7940HX has 16 cores and 32 threads. Despite having fewer cores, the AMD part’s higher thread count (32 vs. 28) contributes to its multi-threaded performance advantage.

Q: How do the two compare in average benchmark score?

A: The AMD Ryzen 9 7940HX has an average benchmark score of 60,695, which is 1.8% higher than the Intel Core i7-14700’s 59,621. Both processors rank in the 95th percentile of all CPUs.

Q: Which chip wins in single-threaded performance?

A: The Intel Core i7-14700 wins in the Passmark single-thread test with a score of 4,270 versus 3,953 for the AMD Ryzen 9 7940HX, a margin of 8%. However, the AMD part wins all Cinebench single-core tests (R15, R20, R23) by 22.9% to 23%.

Q: What is the biggest performance gap between the two?

A: The largest difference is in Passmark extended instructions, where the AMD Ryzen 9 7940HX scores 52,217 versus 29,405 for the Intel Core i7-14700, a delta of 43.7% in AMD’s favor.

Q: Are both processors currently in production?

A: Yes, both the Intel Core i7-14700 and the AMD Ryzen 9 7940HX have an active production status. The Intel chip was released on January 7, 2024, while the AMD chip followed on January 16, 2024.

Q: Do both processors support the same memory type?

A: No. The Intel Core i7-14700 supports both DDR4 and DDR5 memory, while the AMD Ryzen 9 7940HX supports only DDR5. The AMD part also has a specified memory bandwidth of 83.2 GB/s, which the Intel chip lacks in the data.

Architecture Differences

The two processors diverge sharply at the architectural level. The Intel Core i7-14700 is built on Intel’s Raptor Lake architecture, specifically the Raptor Lake-R refresh, using a 10 nm process node manufactured by Intel. Its 20 cores comprise a hybrid layout that is typical of Raptor Lake, with a die size of 257 mm². In contrast, the AMD Ryzen 9 7940HX uses the Zen 4 architecture under the Dragon Range codename, fabricated on a 5 nm process at TSMC. The AMD chip integrates 13,140 million transistors across a dual-die design measuring 2x 71 mm², totaling 142 mm²—a smaller physical footprint than Intel’s monolithic die.

Cache hierarchies also differ notably. Intel allocates 80 KB of L1 cache per core and 2 MB of L2 per core, with a shared 33 MB L3 cache. AMD uses 64 KB L1 per core and 1 MB L2 per core, but provides a much larger shared 64 MB L3 cache. This doubled L3 capacity likely contributes to AMD’s significant wins in memory-sensitive workloads like Passmark random string sorting, where it leads by 32.7%. The AMD chip also features an unlocked multiplier, whereas the Intel part is locked, and the AMD CPU exposes 28 PCIe Gen 5 lanes versus Intel’s 16 lanes.

The market positioning is reflected in the sockets and integrated graphics. Intel uses Socket 1700 with UHD Graphics 770, while AMD uses Socket FL1 with the Radeon 610M. The Intel chip supports ECC memory; the AMD part does not. Power envelopes differ as well, with Intel rated at a 65 W TDP and AMD at 55 W, though the AMD chip is a mobile processor and the Intel chip is desktop-class. The process node advantage (5 nm vs. 10 nm) and the larger L3 cache are the most probable drivers of AMD’s benchmark dominance.

The Verdict

Based strictly on the benchmark data, the AMD Ryzen 9 7940HX is the superior performer for almost every workload. It wins 15 of the 17 head-to-head comparisons, including all Cinebench tests (R15, R20, R23) in both single-core and multi-core, with deltas ranging from 10.6% to 23%. In Passmark workloads, AMD leads by double digits in data compression (27.1%), encryption (28.2%), integer math (22.5%), multithread (23%), and random string sorting (32.7%). The only test where Intel wins is Passmark single-thread (4,270 vs. 3,953, an 8% margin), and the two are nearly tied in Passmark physics (2,307 vs. 2,313, a 0.3% difference). Users who prioritize raw multi-threaded throughput, encryption, or instruction-heavy workloads should choose the AMD Ryzen 9 7940HX.

The Intel Core i7-14700’s case rests on its single-thread Passmark score and its desktop platform benefits. It is the only chip among the two with ECC memory support and DDR4 compatibility, and it carries a launch MSRP of $384, whereas the AMD part has no listed launch MSRP. For workloads that favor the Passmark single-thread metric, the Intel chip is 8% faster. However, the Cinebench single-core tests tell the opposite story, with AMD leading by 23% in R23 single-core (6,469 vs. 4,981). The data indicates that the AMD Ryzen 9 7940HX is the better choice for compute-heavy tasks, while the Intel chip is preferable for legacy memory compatibility or ECC requirements. Given AMD’s near-total sweep of the head-to-head tests, the 7940HX is the stronger processor overall.

Specification Differences

The two CPUs differ across nearly every fundamental specification except for production status and release timing. The Intel Core i7-14700 has 20 cores and 28 threads, while the AMD Ryzen 9 7940HX has 16 cores and 32 threads. Clock speeds are close: Intel’s base is 2.10 GHz with a 5.40 GHz boost, versus AMD’s 2.40 GHz base and 5.20 GHz boost. The Intel chip has a higher TDP (65 W vs. 55 W) and uses Socket 1700, while AMD uses Socket FL1. The process node is a major difference—Intel is on 10 nm, AMD on 5 nm—with the AMD part manufactured by TSMC and featuring 13,140 million transistors across 2x 71 mm² dies, compared to Intel’s 257 mm² monolithic die.

Cache configurations diverge: Intel has 80 KB L1 and 2 MB L2 per core with 33 MB shared L3; AMD has 64 KB L1 and 1 MB L2 per core with 64 MB shared L3. Memory support differs, with Intel supporting DDR4 and DDR5 and AMD supporting only DDR5; AMD also specifies 83.2 GB/s memory bandwidth. ECC memory is supported only on Intel. PCIe lanes favor AMD (Gen 5, 28 lanes vs. Gen 5, 16 lanes). Integrated graphics are UHD Graphics 770 on Intel and Radeon 610M on AMD. The Intel chip has a locked multiplier, while AMD’s is unlocked. Intel lists a launch MSRP of $384; AMD has none.

Head-to-Head Benchmarks

The benchmark results are decisively lopsided in favor of the AMD Ryzen 9 7940HX. Across the Cinebench suite, AMD leads every test by nearly the same margin. In Cinebench R15 multi-core, AMD scores 4,618 against Intel’s 3,556, a 23% advantage. The single-core R15 test shows 651 vs. 502, a 22.9% delta. Cinebench R20 multi-core (19,245 vs. 14,820) and single-core (2,716 vs. 2,092) both show a 23% lead for AMD. The pattern holds in Cinebench R23: multi-core 45,822 vs. 35,287 and single-core 6,469 vs. 4,981, each 23% in AMD’s favor. This consistency suggests a fundamental per-thread efficiency advantage for Zen 4, not just a core-count effect.

In Passmark workloads, AMD’s wins are larger. Data compression shows 706,097 vs. 514,933 (27.1% delta), and data encryption shows 42,557 vs. 30,569 (28.2% delta). Extended instructions produce the largest gap: 52,217 vs. 29,405, a 43.7% lead for AMD. Find prime numbers yields 274 vs. 170 (38% delta), and random string sorting shows 83,100 vs. 55,958 (32.7% delta). Integer math is 205,157 vs. 159,034 (22.5% delta), and multithread is 53,904 vs. 41,524 (23% delta). Floating-point math is closer at 122,952 vs. 109,880, a 10.6% lead for AMD. Physics is essentially a tie: 2,313 vs. 2,307, a 0.3% delta.

The Intel Core i7-14700’s only wins are in Passmark single-thread, where it scores 4,270 versus AMD’s 3,953, an 8% margin. This appears in both the "single_thread" and "singlethread" test entries, which are identical. The average benchmark score also favors AMD slightly (60,695 vs. 59,621), and the nearest rivals list confirms the two are close: AMD’s average score is 1.8% higher than Intel’s, and both are within 1.9% of the Intel Core i9-14900F. The 15-2 win count in head-to-head tests leaves no ambiguity: the AMD Ryzen 9 7940HX is the performance leader, with Intel’s single-thread Passmark win being the lone counterpoint.
