AMD Ryzen 9 7940HS vs Intel Core i7-12700F Comparison

The AMD Ryzen 9 7940HS and Intel Core i7-12700F represent two very different philosophies: a 35W mobile flagship built on TSMC's 4nm process versus a 65W desktop part from Intel's 10nm Alder Lake generation. While the Intel chip wins the majority of head-to-head tests (15 of 23), the AMD processor’s victories are concentrated in specific workloads that reveal a more modern architecture. Both CPUs land at the 82nd percentile among all processors, with the Ryzen 9 7940HS posting an average benchmark score of 31,593 against the Core i7-12700F’s 31,081 — a razor-thin 1.6% overall margin that masks significant per-test swings.

Head-to-Head Benchmarks

The most dramatic gap in the entire comparison belongs to Intel in floating-point math. The Core i7-12700F scores 81,804 in PassMark’s floating-point test, a 23.1% advantage over the Ryzen 9 7940HS’s 62,897. This is the single largest delta in either direction and signals a clear edge for the desktop chip in scientific and engineering workloads that rely heavily on FPU throughput.

Intel also dominates in thread-scaled 3DMark tests. The 3DMark max-threads score favors the Core i7-12700F by 19.6% (9,403 vs 7,558), while the 16-thread test shows a 13.5% lead (8,733 vs 7,553). The 8-thread test narrows to a 6.9% advantage (6,667 vs 6,205), and the 4-thread test to 2.9% (3,837 vs 3,725). Even the 2-thread test goes Intel’s way, though by just 1.6% (1,983 vs 1,952).

The AMD Ryzen 9 7940HS strikes back hardest in Cinebench R23 multi-core, where it posts 16,713 to Intel’s 15,291 — a 9.3% victory. That result is backed by a 1.8% win in Cinebench R15 multi-core (2,656 vs 2,610) and a 4.4% lead in Cinebench R15 single-core (283 vs 271). The Ryzen also takes PassMark’s extended instructions test by 10.9% (27,480 vs 24,783) and data encryption by 7.9% (21,777 vs 20,185).

Single-thread performance is essentially a coin flip. The Core i7-12700F edges ahead in 3DMark single-thread by 0.2% (1,005 vs 1,003), Geekbench single-core by 1.2% (2,169 vs 2,144), and Cinebench R23 single-core by 5.7% (1,898 vs 1,790). But the Ryzen 9 7940HS wins PassMark single-thread by 0.7% (3,878 vs 3,850). In Geekbench multi-core, Intel leads by 2.4% (13,039 vs 12,724).

Other notable Intel wins include PassMark floating-point math (already noted), data compression by 5% (384,463 vs 365,352), find prime numbers by 6.1% (98 vs 92), integer math by 3.7% (107,013 vs 103,044), multi-thread by 1.1% (30,445 vs 30,098), and physics by 2.6% (1,488 vs 1,450). AMD counterpoints with random string sorting at 6.4% (42,386 vs 39,852).

Where Each One Wins

The Intel Core i7-12700F is the clear choice for floating-point-heavy computation. Its 23.1% lead in PassMark floating-point math dwarfs every other benchmark difference. It also wins all five 3DMark thread-scaled tests, suggesting better scaling across 2, 4, 8, 16, and max-thread configurations. The desktop chip handles data compression 5% better and integer math 3.7% better, making it the stronger pick for general productivity, database work, and compression tasks.

The AMD Ryzen 9 7940HS excels in Cinebench R23 multi-core, beating Intel by 9.3% despite running at a 35W TDP versus Intel’s 65W. That result, combined with a 10.9% win in extended instructions and 7.9% in data encryption, points to superior efficiency per watt in bursty, AVX-style workloads. The Ryzen also wins random string sorting by 6.4%, which suggests an advantage in memory-access patterns or sorting algorithms.

For single-thread applications, the data is too close to call. The two chips trade wins across different single-thread tests, with the largest gap being Intel’s 5.7% Cinebench R23 single-core advantage. Users who prioritize raw multi-core rendering in Cinebench should favor AMD; those who need FPU throughput or heavy thread scaling should look at Intel.

Architecture Differences

The fundamental divergence starts with process node and foundry. The AMD Ryzen 9 7940HS uses TSMC’s 4nm process with 25,000 million transistors on a 178 mm² die. Intel’s Core i7-12700F uses Intel’s 10nm process on a larger 215 mm² die, with transistor count not listed in the data. This node advantage likely explains AMD’s ability to hit a 5.20 GHz boost clock at 35W TDP compared to Intel’s 4.90 GHz boost at 65W TDP.

Core configuration is another major split. The Ryzen 9 7940HS has 8 cores and 16 threads, all based on Zen 4 architecture (codename Phoenix). The Core i7-12700F has 12 cores and 20 threads using Alder Lake architecture (Alder Lake-S), which combines performance and efficiency cores — though the data pack does not specify the P-core/E-core split. Intel’s higher core and thread counts explain its wins in thread-scaled tests, while AMD’s newer Zen 4 architecture likely contributes to its Cinebench R23 multi-core victory despite fewer threads.

Cache hierarchies differ notably. Intel provides 80 KB L1 and 1.25 MB L2 per core, with 25 MB shared L3. AMD offers 64 KB L1 and 1 MB L2 per core, with 16 MB shared L3. Intel’s larger per-core caches and bigger L3 pool may support its compression and integer math wins. The Ryzen counterbalances with a higher base clock of 4.00 GHz versus Intel’s 2.10 GHz, though Intel’s boost reaches 4.90 GHz.

Memory support is a key differentiator. The Ryzen 9 7940HS supports DDR5 with dual-channel memory and 89.6 GB/s bandwidth, plus ECC memory. The Core i7-12700F supports both DDR4 and DDR5 in dual-channel mode, though its memory bandwidth is not listed, and it lacks ECC support. PCIe also splits: AMD offers Gen 4 with 20 CPU lanes, while Intel provides Gen 5 with 16 CPU lanes.

The Ryzen 9 7940HS includes integrated Radeon 780M graphics, while the Core i7-12700F has no integrated graphics listed. This makes AMD the only option here for a system without a discrete GPU, especially relevant given its mobile market segment. Intel’s part targets desktop with Socket 1700; AMD uses Socket FP8. The Ryzen is part of AMD’s 7000 series, and Intel is Core 12th Gen.

The Verdict

The Intel Core i7-12700F is the stronger all-around performer for most workloads, winning 15 of 23 tests with decisive margins in floating-point math (23.1%), max-thread 3DMark (19.6%), and 16-thread 3DMark (13.5%). Its 12 cores and 20 threads, larger 25 MB L3 cache, and dual DDR4/DDR5 support make it the pick for compression, integer math, and thread-scaled rendering tasks. The 65W TDP and desktop Socket 1700 footprint suit it for a full-size tower where power is less constrained.

The AMD Ryzen 9 7940HS wins where architecture efficiency matters most. Its 9.3% Cinebench R23 multi-core lead at nearly half the TDP (35W vs 65W) is the standout result, followed by 10.9% in extended instructions and 7.9% in data encryption. The integrated Radeon 780M and ECC support give it versatility that Intel lacks entirely. For a mobile platform or a compact system where power draw and integrated graphics are priorities, the Ryzen 9 7940HS is the data-backed choice.

Both chips sit at the 82nd percentile, and their nearest rivals confirm they are closely matched: the Ryzen 9 7940HS is just 0.3% above the Intel Core i5-13500, while the Core i7-12700F is effectively tied with the AMD Ryzen 9 8945HS at 0% delta. The final decision hinges on whether you favor Intel’s 15-test win count and FPU dominance, or AMD’s superior multi-core Cinebench score and platform features like ECC and integrated graphics.
