AMD Ryzen 7 7735U vs Intel Core i5-12600KF Comparison

The Verdict

The data set is unusually one-sided. The Intel Core i5-12600KF wins all 17 head-to-head benchmark comparisons against the AMD Ryzen 7 7735U, with zero wins for the AMD part. If raw compute performance is the sole criterion, the i5-12600KF is the clear pick for any desktop workload that benefits from high multi-threaded and single-threaded throughput.

However, the two chips serve entirely different market segments. The i5-12600KF is a desktop processor with a 125 W TDP, an unlocked multiplier, and a launch MSRP of $264. The Ryzen 7 7735U is a mobile part with a 28 W TDP, a locked multiplier, and integrated Radeon 680M graphics. The data shows the i5-12600KF is 131.9% ahead in Cinebench R23 multi-core and 121.6% ahead in single-core. That is not a close contest.

Choose the i5-12600KF if you are building a desktop system where power draw is not the primary constraint and you want maximum CPU performance for the price tier. Choose the Ryzen 7 7735U if you need a mobile processor with integrated graphics, lower power consumption, and ECC memory support, and you can accept significantly lower benchmark scores. The Ryzen 7 7735U still holds an 80th percentile ranking among all CPUs, so it is not a slow chip; it is simply outclassed by the Intel part in every measured test.

Architecture Differences

The Intel Core i5-12600KF uses the Alder Lake architecture, built on Intel's 10 nm process with a die size of 215 mm². It has 10 cores and 16 threads. The cache layout is 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. It supports DDR4 and DDR5 memory in a dual-channel configuration. The CPU provides 20 PCIe Gen 4 lanes. It has no integrated graphics, which means a discrete GPU is required. The multiplier is unlocked, and it uses the Intel Socket 1700.

The AMD Ryzen 7 7735U uses the Zen 3+ architecture, codenamed Rembrandt-R, built on TSMC's 6 nm process with a die size of 208 mm². It has 8 cores and 16 threads. The cache layout is 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. It supports DDR5 memory only, in a dual-channel configuration, with a memory bandwidth of 76.8 GB/s. It also provides 20 PCIe Gen 4 lanes. It includes integrated Radeon 680M graphics, supports ECC memory, and has a locked multiplier. The socket is AMD Socket FP7.

The architectural split is clear: Intel uses a larger process node (10 nm vs 6 nm) and a larger die (215 mm² vs 208 mm²), but AMD packs more L3 cache per core relative to its thread count. The Intel part has 10 cores versus 8, and its L3 cache is 20 MB versus 16 MB. The AMD part compensates with a smaller process node and integrated graphics, which the Intel desktop part completely lacks.

Head-to-Head Benchmarks

The most dramatic gap appears in Cinebench R23 multi-core, where the i5-12600KF scores 23391 against 10085 for the Ryzen 7 7735U, a 131.9% difference. The single-core R23 result is similarly lopsided: 3302 versus 1490, a 121.6% gap. In Cinebench R15, the Intel part leads multi-core by 38.8% (2357 vs 1698) and single-core by 41.9% (332 vs 234). These are massive margins, not incremental leads.

Geekbench results follow the same pattern. Multi-core shows 12137 for Intel against 7216 for AMD, a 68.2% lead. Single-core is 2157 versus 1442, a 49.6% lead. The Passmark suite confirms the trend across every category. In integer math, the Intel part scores 87830 versus 79580, a relatively modest 10.4% lead. In floating point math, the gap widens to 56.1% (67074 vs 42966). Data compression shows a 37% lead (343231 vs 250457). Data encryption is closer at 16.6% (18445 vs 15825). Extended instructions show a 34.6% lead (22003 vs 16349). Prime number finding is a 59.6% lead (91 vs 57). Physics simulation is a 54.5% lead (1539 vs 996). Random string sorting is a 35% lead (35602 vs 26365). Passmark multi-thread shows a 33.1% lead (27575 vs 20723), and single-thread shows a 21.3% lead (3925 vs 3236).

The smallest margin is integer math at 10.4%, which suggests the AMD part has competitive integer throughput per core. The largest margins are in Cinebench R23, where the Intel part more than doubles the AMD score. The database also records 3DMark results for the Intel part only: 7956 in 16-thread, 1995 in 2-thread, 3806 in 4-thread, 6128 in 8-thread, 7952 in max-thread, and 1016 in single-thread. The Ryzen 7 7735U has no recorded 3DMark scores, so no direct comparison is possible in that suite.

Specification Differences

The two processors differ in nearly every core specification. The Intel part has 10 cores versus 8, a base clock of 3.70 GHz versus 2.70 GHz, and a boost clock of 4.90 GHz versus 4.75 GHz. The TDP is 125 W for Intel versus 28 W for AMD, a 97 W gap that explains the performance difference in sustained workloads. The Intel part uses Socket 1700; the AMD part uses Socket FP7.

Cache sizes differ as well. Intel has 80 KB L1 per core against 64 KB, and 1.25 MB L2 per core against 512 KB. The L3 cache is 20 MB shared versus 16 MB shared. Memory support differs: Intel supports both DDR4 and DDR5, while AMD supports only DDR5. The AMD part has a recorded memory bandwidth of 76.8 GB/s, while Intel has no such figure in the database. ECC memory is supported only on the AMD part. Integrated graphics are present only on the AMD part (Radeon 680M); the Intel part has none. The multiplier is unlocked on Intel, locked on AMD. The process node is 10 nm for Intel versus 6 nm for AMD, with the foundry being Intel versus TSMC.

The release dates differ: Intel launched on 2021-11-03, AMD on 2023-01-03. The Intel part has a launch MSRP of $264; the AMD part has no recorded launch MSRP. The Intel part number is SRL4U; the AMD part number is 100-000000987 (FP7) or 100-000000991 (FP7r2). Both are marked as Active production status. Both support dual-channel memory and 20 PCIe Gen 4 lanes.

Q: How do their average benchmark scores compare overall?

A: The AMD Ryzen 7 7735U has a higher average benchmark score of 28350 against 27799 for the Intel part. This is despite losing every head-to-head test, which indicates the AMD part's average is buoyed by its performance relative to the broader CPU population. The AMD part sits at the 80th percentile among all CPUs, while the Intel part sits at the 79th percentile.

Where Each One Wins

The Intel Core i5-12600KF wins in every measured compute workload. The largest advantages are in Cinebench R23 multi-core (131.9% lead) and single-core (121.6% lead), which represent sustained all-core rendering and lightly threaded tasks respectively. It also leads heavily in floating point math (56.1%), physics simulation (54.5%), and prime number finding (59.6%). For content creation, 3D rendering, scientific computing, and any task that scales with thread count, the data clearly favors the Intel part.

The AMD Ryzen 7 7735U does not win any benchmark, but its use case is different. It has a 28 W TDP versus 125 W for Intel, which makes it suitable for thin-and-light laptops where power draw and heat output are critical constraints. It includes integrated Radeon 680M graphics, so it can handle display output and light graphics work without a discrete GPU. It supports ECC memory, which is valuable for certain workstation or server scenarios where data integrity matters more than raw speed. Its average benchmark score is slightly higher (28350 vs 27799), and it sits at a higher percentile (80th vs 79th), indicating that relative to the entire CPU landscape, it is not a weak processor. The Intel part is simply a much stronger performer in every direct comparison.

For a desktop builder who wants maximum CPU throughput and can supply adequate cooling and power, the i5-12600KF is the obvious choice. For a mobile user who needs a low-power processor with integrated graphics and ECC support, the Ryzen 7 7735U is the only viable option among these two, despite its lower scores.
