AMD Ryzen 5 7535HS vs Intel Core i5-12400 Comparison

Head-to-Head Benchmarks

The benchmark comparison between the AMD Ryzen 5 7535HS and Intel Core i5-12400 shows a decisive overall victory for Intel, with 17 wins against 6 for AMD. However, the margin of victory varies dramatically across workload types, revealing distinct strengths for each processor.

The single largest gap appears in Cinebench R23 multi-core, where the Intel Core i5-12400 scores 15,989 against the AMD's 8,613, a delta of -46.1%. This near-doubling of multi-threaded rendering performance is the most lopsided result in the entire comparison. The same test in single-core shows Intel ahead by 36%, with scores of 2,257 versus 1,445. These Cinebench results indicate a substantial architectural advantage for Intel in sustained multi-core workloads.

Geekbench results follow the same pattern. Intel leads multi-core with 8,564 versus 7,354, a 14.1% advantage, and single-core with 1,848 versus 1,654, a 10.5% edge. The 3DMark suite shows Intel winning the 16-thread test (5,873 vs 5,292, -9.9%), the max-thread test (5,890 vs 5,285, -10.3%), the 8-thread test (4,745 vs 4,537, -4.4%), and the single-thread test (910 vs 872, -4.2%). The only 3DMark exception is the 4-thread test, where AMD wins 3,164 versus 3,012, a 5% advantage.

PassMark results are mixed. Intel wins the multithread test 18,747 versus 17,914 (-4.4%), floating point math 45,494 versus 35,540 (-21.9%), physics 1,105 versus 844 (-23.6%), find prime numbers 68 versus 49 (-27.9%), and single-thread 3,456 versus 3,123 (-9.6%). AMD counters with wins in integer math (62,372 vs 58,366, +6.9%), data encryption (13,656 vs 11,418, +19.6%), extended instructions (15,411 vs 15,399, +0.1%), and random string sorting (22,781 vs 22,366, +1.9%). Data compression is nearly a tie, with Intel ahead 226,908 versus 221,668 (-2.3%).

The Cinebench R15 results are notable: Intel wins multi-core 1,611 versus 1,457 (-9.6%), but AMD wins single-core 232 versus 227 (+2.2%). This single-core R15 win is one of only two AMD victories outside of PassMark (the other being the 3DMark 4-thread test).

Architecture Differences

The two processors represent fundamentally different design philosophies. The AMD Ryzen 5 7535HS uses the Zen 3+ architecture, codenamed Rembrandt-R, built on a 6 nm process at TSMC. The Intel Core i5-12400 uses Alder Lake-S architecture on Intel's 10 nm process. Both have 6 cores and 12 threads, but the similarities end there.

The AMD processor is a mobile part with a 35 W TDP, while the Intel chip is a desktop processor rated at 65 W TDP. This power envelope difference helps explain the large Cinebench R23 multi-core gap, as the Intel part can sustain higher clocks under load. The AMD base clock is 3.30 GHz with a boost of 4.55 GHz, while Intel runs at 2.50 GHz base and 4.40 GHz boost. Despite the lower base clock, Intel's higher sustained performance suggests better power delivery and thermal headroom in desktop conditions.

Cache hierarchies differ substantially. AMD provides 64 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3. Intel offers 80 KB L1 per core, 1.25 MB L2 per core, and 18 MB shared L3. Intel's larger per-core L2 and total L3 likely contribute to its single-thread performance advantage, while AMD's smaller cache footprint may explain its mixed results in certain workloads.

Memory support is another differentiator. AMD supports DDR5 only, with dual-channel configuration and 76.8 GB/s bandwidth. Intel supports both DDR4 and DDR5 in dual-channel mode, offering flexibility for system builders. Neither supports ECC memory. PCIe connectivity differs: AMD provides Gen 4 with 20 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only). Intel's newer PCIe generation offers more bandwidth per lane, though AMD has more total lanes.

The integrated graphics differ as well. AMD uses Radeon 660M, while Intel uses UHD Graphics 730. Both are active production parts. The AMD processor uses AMD Socket FP7, while Intel uses Socket 1700. The AMD die size is 208 mm², larger than Intel's 163 mm². Neither processor has an unlocked multiplier.

Where Each One Wins

The Intel Core i5-12400 is the clear choice for multi-threaded rendering and content creation workloads. The Cinebench R23 multi-core result is decisive: Intel scores 15,989 versus AMD's 8,613, a 46.1% advantage. This extends to Cinebench R15 multi-core, where Intel leads 1,611 versus 1,457. For users running video encoding, 3D rendering, or other heavily threaded production tasks, the data strongly favors Intel.

Intel also wins in general-purpose computing. Geekbench multi-core shows a 14.1% lead, and single-core a 10.5% lead. The 3DMark suite, which simulates gaming workloads, shows Intel ahead in most thread counts, including a 10.3% advantage at max threads. Floating point math is another Intel strength, with a 21.9% lead. Physics calculations, important for gaming engines, favor Intel by 23.6%. Prime number finding, a test of integer-heavy iterative work, shows Intel ahead by 27.9%.

The AMD Ryzen 5 7535HS has a narrower but distinct set of strengths. Data encryption is its biggest win, scoring 13,656 versus 11,418, a 19.6% advantage. This suggests AMD's cryptographic instruction implementation is more efficient. Integer math favors AMD by 6.9%, which could benefit certain calculation-heavy workloads. The extended instructions test shows a marginal 0.1% AMD lead, and random string sorting shows a 1.9% advantage.

The 3DMark 4-thread test is an interesting outlier, with AMD winning 3,164 versus 3,012 (5%). This suggests AMD's mid-range thread scaling is efficient relative to Intel. Cinebench R15 single-core also favors AMD by 2.2%, a small but real win.

For mobile users, the AMD's 35 W TDP is a significant factor. The Intel desktop part requires 65 W, which typically means a larger cooling solution and power supply. The AMD processor's mobile market segment and lower TDP make it suitable for thin-and-light laptops, while the Intel part is designed for desktop systems with more thermal headroom.
