AMD Ryzen AI 5 435 vs AMD Ryzen AI 5 PRO 340 Comparison

Both AMD Ryzen AI 5 parts are 6-core/12-thread Zen 5 mobile processors on the same 4 nm TSMC node and FP8 socket, but the benchmark data reveals they are not identical performers. The Ryzen AI 5 PRO 340 takes the overall win count 10 to 5, powered by a higher 4.80 GHz boost clock and double the L3 cache. However, the Ryzen AI 5 435 fights back with wins in several specific workloads, including a single-core Cinebench victory and a notable 3% lead in extended instructions. The choice between them hinges on whether you need the PRO 340's broad multi-threaded and integer strength or the 435's targeted advantages in floating-point, compression, and sorting tasks.

FAQ

A: The largest delta is in PassMark find prime numbers, where the PRO 340 scores 74 versus the 435's 58, a 21.6% advantage. The next biggest gap is the 5.8% lead for the PRO 340 in Cinebench R15 single-core.

Q: Which CPU has a higher boost clock and what is the difference?

A: The Ryzen AI 5 PRO 340 has a boost clock of 4.80 GHz, which is 0.30 GHz higher than the Ryzen AI 5 435's 4.50 GHz boost. Both have the same 2.00 GHz base clock.

Architecture Differences

Both processors are built on the Zen 5 architecture, but they belong to different generations and codenames. The Ryzen AI 5 435 is from the Ryzen AI 400 series, codenamed Gorgon Point, while the Ryzen AI 5 PRO 340 is from the Ryzen AI PRO 300 series, codenamed Krackan Point. Despite this generational split, both share the same 4 nm TSMC process node and use a combination of Zen 5 and Zen 5c cores in their 6-core, 12-thread configuration.

The most significant architectural divergence is in cache hierarchy. The 435 is equipped with a 4 MB L3 cache, whereas the PRO 340 doubles that to 8 MB. This larger shared cache on the PRO 340 likely contributes to its superior performance in multi-threaded and integer-heavy tasks where data reuse is critical. Both chips offer 80 KB of L1 and 1 MB of L2 per core, so the difference is isolated to the last-level cache.

Other specifications are largely identical. Both use the AMD Socket FP8, support dual-channel DDR5 and LPDDR5X memory with 89.6 GB/s bandwidth, and include ECC memory support. The integrated graphics are the same Radeon 840M on both parts. The primary clock difference is the PRO 340's boost clock of 4.80 GHz versus the 435's 4.50 GHz, while base clocks are equal at 2.00 GHz. Both are unlocked multipliers, but the PRO 340 offers slightly more PCIe connectivity with 16 Gen 4 lanes (CPU only) versus the 435's 14 lanes. The PRO 340 also has a published die size of 195 mm², while that data is not listed for the 435.

Head-to-Head Benchmarks

The benchmark data shows a clear split in workload types. The Ryzen AI 5 PRO 340 dominates in integer and multi-threaded performance, while the Ryzen AI 5 435 excels in floating-point and specific data-processing tasks. Starting with the PRO 340's wins, its 21.6% lead in PassMark find prime numbers (74 vs 58) is the largest margin in the entire comparison, indicating a substantial advantage in integer-heavy algorithmic loops. It also leads in integer math by 3.5% (63233 vs 61026) and in Cinebench R15 multi-core by 3.3% (1743 vs 1686).

The PRO 340's single-core advantage is most pronounced in Cinebench R15, where it scores 276 versus 260, a 5.8% margin. Its Cinebench R23 multi-core lead is more modest at 1.7% (11534 vs 11333). Smaller wins for the PRO 340 include data encryption (0.9%, 11212 vs 11110), PassMark multithread (1.1%, 19215 vs 19000), physics (0.8%, 1084 vs 1075), and single-thread (0.6%, 3758 vs 3734).

The Ryzen AI 5 435's victories are narrower but consistent in specific areas. Its best win is in PassMark extended instructions, where it leads by 3% (16197 vs 15721). The 435 also wins floating-point math by 2.4% (40627 vs 39662) and random string sorting by 2.3% (24891 vs 24334). In data compression, it takes a 1.7% lead (225374 vs 221581). The 435's only single-core win is in Cinebench R23 single-core, where it edges out the PRO 340 by 0.8% (1816 vs 1802).

The aggregate averages tell a similar story. The 435 has an average benchmark score of 28128, placing it 0.2% behind the Intel Core i5-13490F and 0.2% ahead of the Intel Core i5-14500T. The PRO 340's average of 27932 puts it 0.1% ahead of the AMD Ryzen 7 5800X3D and 0.2% ahead of the AMD Ryzen 7 6800U. Both CPUs sit in the 80th percentile of all CPUs, indicating they are closely matched in overall capability.

Specification Differences

The core configuration is identical: both have 6 cores, 12 threads, a 2.00 GHz base clock, 28 W TDP, and 4 nm TSMC fabrication. The key differences are as follows:

• Boost Clock: The PRO 340 reaches 4.80 GHz, while the 435 tops out at 4.50 GHz.
• L3 Cache: The PRO 340 has 8 MB, double the 435's 4 MB.
• Codename/Generation: The 435 is Gorgon Point from the Ryzen AI 400 series; the PRO 340 is Krackan Point from the Ryzen AI PRO 300 series.
• PCIe Lanes: The PRO 340 offers 16 Gen 4 lanes (CPU only), versus 14 on the 435.
• Die Size: The PRO 340 lists a 195 mm² die size; the 435 does not report this figure.
• Release Date: The PRO 340 launched on 2025-01-05, while the 435 came later on 2026-01-04.
• Part Number: 100-000001600 for the PRO 340, 100-000001337 for the 435.

All other fields—memory support (DDR5, LPDDR5X), memory bus (dual-channel), memory bandwidth (89.6 GB/s), ECC support, integrated graphics (Radeon 840M), socket (FP8), and locked multiplier status—are identical.

The Verdict

The data points to the AMD Ryzen AI 5 PRO 340 as the stronger all-around processor for compute-heavy tasks. It wins 10 of the 15 head-to-head benchmarks, including all Cinebench multi-core tests and the majority of PassMark integer and threading tests. Its 21.6% advantage in prime number finding and 3.5% lead in integer math make it the clear choice for workloads that stress arithmetic logic and parallel execution. The higher 4.80 GHz boost clock and doubled 8 MB L3 cache are the likely drivers of this broad superiority.

The Ryzen AI 5 435 is not without merit. Its 3% lead in extended instructions suggests better optimization for SIMD or specialized instruction sets, and its 2.4% win in floating-point math makes it preferable for scientific or graphical calculations. The 435 also wins in data compression and random string sorting, which are common in database and file-management tasks. Its single-core win in Cinebench R23, while narrow, shows it can hold its own in lightly threaded scenarios.

The overall average benchmark scores are nearly identical—28128 for the 435 versus 27932 for the PRO 340, a difference of less than 1%. Both rank in the 80th percentile of all CPUs. For a buyer or system integrator choosing between the two, the PRO 340's extra cache and higher clock deliver more consistent wins across the board, making it the safer pick for general productivity and multi-threaded applications. The 435 should be selected only when the specific workloads it wins—floating-point math, extended instructions, compression, and string sorting—are the priority.
