AMD Ryzen 7 7735H vs Intel Core Ultra 5 225F Comparison

The Intel Core Ultra 5 225F and AMD Ryzen 7 7735H are both active processors that land in the 85th percentile of all CPUs, yet they are built for fundamentally different roles. The data shows a desktop part with a 65W TDP and a mobile part with a 35W TDP, yet their average benchmark scores are nearly identical — 37313 for the Intel and 37161 for the AMD. This makes the head-to-head comparison a study in how architectural priorities and thread counts can offset each other in real-world workloads.

Head-to-Head Benchmarks

The Intel Core Ultra 5 225F dominates the benchmark suite, winning 14 of the 15 recorded tests. The scale of that victory varies dramatically by workload. In Cinebench R23 multi-core, the Intel scores 16467 against the AMD's 10920, a 50.8% advantage. The gap is even more pronounced in Cinebench R15 multi-core, where the Intel's 2660 beats the AMD's 1825 by 45.8%. These are not marginal wins; they represent a generational leap in sustained multi-threaded throughput.

Single-thread performance tells a similar story, albeit with a smaller margin. The Intel leads Cinebench R23 single-core by 23.2% (1893 vs 1536) and Cinebench R15 single-core by 16.7% (287 vs 246). The PassMark single-thread test shows a 33.7% gap (4397 vs 3288). This consistent single-core advantage points to the Intel's higher 4.90GHz boost clock and newer architecture, which matter even when the AMD's 16 threads could theoretically help in lightly threaded tasks.

Some of the most striking deltas appear in specialized workloads. The PassMark find prime numbers test shows the Intel scoring 352 against the AMD's 59 — a 496.6% difference that suggests a massive efficiency advantage in integer-heavy, latency-sensitive loops. Floating-point math also favors the Intel heavily: 92554 vs 49260, a 87.9% lead. Physics simulation, another floating-point-heavy test, shows the Intel at 2430 vs the AMD's 1056, a 130.1% advantage.

The Intel also wins in memory-bandwidth-sensitive tasks. Data encryption shows a 19.3% lead (22648 vs 18990), and extended instructions come in 32.1% higher (28027 vs 21214). Even random string sorting, which often rewards cache size, goes to the Intel by 17.8% (37325 vs 31676). Data compression is the closest Intel win at just 2.4% (310843 vs 303502), indicating the AMD's 16 threads can nearly overcome the Intel's architectural edge in this specific workload.

The AMD's only victory comes in PassMark integer math, where it scores 86788 against the Intel's 66417 — a 23.5% swing in the opposite direction. This is a notable outlier, likely driven by the AMD's 16 threads being able to parallelize integer operations more effectively than the Intel's 10 threads. It is the single benchmark where the AMD's thread count translates into a decisive win.

Where Each One Wins

The Intel Core Ultra 5 225F is the clear choice for any workload that relies on heavy floating-point math or high-frequency single-thread execution. Its 87.9% lead in floating-point math and 130.1% lead in physics make it suited for scientific simulations, 3D rendering, and gaming physics calculations. The 50.8% Cinebench R23 multi-core advantage suggests it handles video encoding and 3D rendering pipelines with significantly more headroom. The 496.6% margin in prime number finding indicates an edge in cryptography and certain mathematical workloads.

The AMD Ryzen 7 7735H's win in integer math (23.5% ahead) points to its strength in database operations, compression algorithms, and general office productivity where integer operations dominate. The data compression result, where the AMD comes within 2.4% of the Intel despite losing nearly every other test, reinforces this. For users running spreadsheet-heavy calculations, legacy code, or certain types of financial modeling, the AMD's integer throughput could be the deciding factor.

Beyond raw compute, the AMD's 35W TDP versus the Intel's 65W means it is designed for systems where thermal headroom is precious. The AMD's integrated Radeon 680M graphics provides display output without a discrete GPU, while the Intel has no integrated graphics at all. This makes the AMD the practical choice for compact laptops or low-power mini PCs, while the Intel is meant for desktops with dedicated graphics.

Specification Differences

The most fundamental difference is core and thread count. The Intel has 10 cores and 10 threads, while the AMD has 8 cores and 16 threads. The AMD's simultaneous multithreading doubles its thread count, while the Intel does not use hyper-threading. Clock speeds differ modestly: the Intel boosts to 4.90 GHz versus the AMD's 4.75 GHz, with base clocks of 3.30 GHz and 3.20 GHz respectively.

TDP is a major differentiator. The Intel is rated at 65W, while the AMD is rated at 35W. This reflects their market segments: the Intel is a desktop part on Intel Socket 1851, while the AMD is a mobile part on AMD Socket FP7. The Intel uses a 3nm process node from TSMC, while the AMD uses a 6nm process node from the same foundry. The Intel's die size is 243 mm² with 17,800 million transistors; the AMD's die size is 208 mm² with no transistor count listed.

Memory bandwidth also differs. The Intel supports 102.4 GB/s, while the AMD supports 76.8 GB/s. Both use dual-channel DDR5. The Intel has no integrated graphics, while the AMD includes Radeon 680M. The Intel supports PCIe Gen 5, the AMD supports PCIe Gen 4, both with 20 lanes. ECC memory is supported only on the AMD. The Intel launched on 2025-01-06 with a launch MSRP of $231; the AMD launched on 2023-03-31 with no launch MSRP listed.

Architecture Differences

The Intel Core Ultra 5 225F is built on Arrow Lake-S architecture, part of the Core Ultra Series 2. It uses a 3nm process from TSMC and features a shared 20MB L3 cache. The AMD Ryzen 7 7735H uses Zen 3+ architecture (codename Rembrandt-R) on a 6nm process, with a shared 16MB L3 cache. The Intel's process node advantage allows for higher clock speeds at a higher TDP.

Cache organization differs significantly. The Intel allocates 192 KB of L1 cache per core and 3 MB of L2 cache per core. The AMD allocates 64 KB of L1 per core and 512 KB of L2 per core. This means the Intel has substantially more per-core cache, which helps explain its dominance in latency-sensitive workloads like prime number finding. The AMD's smaller per-core cache is partially offset by having more threads to share the workload.

The Intel's 10 cores and 10 threads represent a simpler thread model, relying on raw core efficiency rather than multi-threading. The AMD's 8 cores and 16 threads use simultaneous multi-threading to extract more parallelism. The benchmark results show the Intel's approach wins in most tests, but the AMD's thread count gives it a specific edge in integer math, suggesting that certain parallel integer workloads can fully utilize the additional threads.

Feature support differs at the platform level. The Intel uses PCIe Gen 5, which doubles the potential bandwidth for storage and graphics compared to the AMD's PCIe Gen 4. The AMD's ECC memory support makes it suitable for error-sensitive computing environments, a feature absent on the Intel. The AMD's integrated Radeon 680M graphics is a complete GPU solution, whereas the Intel requires a discrete graphics card. The Intel's higher memory bandwidth (102.4 GB/s vs 76.8 GB/s) gives it an advantage in memory-intensive operations, which is reflected in its 87.9% lead in floating-point math and 50.8% lead in multi-core Cinebench R23.
