AMD Ryzen 3 PRO 5355G vs Intel Core i5-14400T Comparison

Head-to-Head Benchmarks

The benchmark data presents a strikingly one-sided contest. Across the eleven comparable PassMark workloads, the Intel Core i5-14400T wins every single test. The AMD Ryzen 3 PRO 5355G records zero wins, while the Intel part takes all eleven. This is not a marginal sweep; the deltas are substantial, ranging from an 11.8% deficit in single-threaded work to a 50.7% shortfall in prime number computation.

The largest gap appears in `passmark_find_prime_numbers`, where the Intel chip scores 73 against the AMD’s 36. That is a 50.7% advantage for Intel, indicating a massive lead in integer-heavy, branch-predictor-sensitive workloads. Floating-point math tells a similar story: Intel scores 49,139 versus AMD’s 25,245, a 48.6% delta. The physics test, which often reflects multi-core scaling in simulation workloads, shows Intel at 1,244 against AMD’s 701, a 43.6% margin.

Multi-threaded throughput also favors Intel decisively. In `passmark_multithread`, Intel scores 20,223 versus 14,033 for AMD, a 30.6% lead. Integer math follows with Intel at 65,667 against 45,910, a 30.1% delta. Data compression shows Intel at 235,636 against 168,041, a 28.7% gap. Even in encryption, where AMD’s Zen 3 architecture is typically competitive, Intel leads 13,244 to 10,288, a 22.3% margin.

The smallest gap is in single-thread performance. Intel’s score of 3,512 in `passmark_single_thread` is only 11.8% higher than AMD’s 3,096. That remains a clear win, but it suggests that in lightly-threaded, latency-sensitive tasks, the AMD part is comparatively closer to parity. Extended instructions also show a moderate gap: Intel at 14,562 versus AMD at 11,935, an 18% delta. Random string sorting completes the sweep, with Intel at 25,181 against 18,819, a 25.3% advantage.

Where Each One Wins

Given the clean sweep, the use-case split is straightforward. The Intel Core i5-14400T wins in every measured category. For workloads that stress multi-core parallelism—rendering, compilation, scientific simulation—the 30.6% lead in multithread score and 43.6% lead in physics suggest a substantial advantage. For single-threaded responsiveness, the 11.8% lead in single-thread score means the Intel part is faster, but the gap is less pronounced.

The AMD Ryzen 3 PRO 5355G, despite losing every benchmark, does have a structural advantage in one dimension: efficiency per core in a smaller package. The data shows it achieves a 79th percentile ranking among all CPUs, matching Intel’s 79th percentile. Its average benchmark score of 27,382 is actually slightly higher than Intel’s 27,166, despite losing every head-to-head test. This is because the AMD part’s nearest rivals include the Intel Core i7-13700H (delta 0.1%) and AMD Ryzen 7 5800 (delta -0.6%), while Intel’s nearest rivals include the Core i9-9900K (delta 0.3%) and Ryzen 7 5700G (delta 0.4%). The aggregate scores place both CPUs in the same performance class, but Intel’s wins are consistent across every workload.

For a user prioritizing raw compute throughput, the Intel part is the clear choice. For a user constrained by power or thermals, the AMD part may be relevant—it has a 65W TDP versus Intel’s 35W TDP, though the data shows Intel accomplishes more work despite the lower thermal envelope. There is no benchmark category where the AMD part emerges victorious, so any use-case analysis must concede that Intel holds the performance lead everywhere measured.

Specification Differences

The two processors differ across nearly every core specification. The AMD Ryzen 3 PRO 5355G has 4 cores and 8 threads, while the Intel Core i5-14400T offers 10 cores and 16 threads. Base clock speeds diverge significantly: AMD runs at 4.00 GHz, while Intel defaults to 1.50 GHz. Boost clocks reverse the order: AMD reaches 4.20 GHz, while Intel boosts to 4.50 GHz.

Thermal design power also differs. The AMD part carries a 65W TDP, while the Intel part is rated at 35W. Sockets are incompatible: AMD uses Socket AM4, Intel uses Socket 1700. Process nodes differ, with AMD on a 7 nm TSMC process and Intel on a 10 nm Intel process. Die size varies, with AMD at 180 mm² and Intel at 215 mm².

Cache hierarchies are dissimilar. AMD provides 64 KB of L1 per core, 512 KB of L2 per core, and 8 MB of L3. Intel provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3. Memory support differs: AMD supports DDR4 only, while Intel supports both DDR4 and DDR5. Memory bandwidth is listed for AMD at 51.2 GB/s, while Intel’s bandwidth is not specified in the data. PCIe generations differ, with AMD offering Gen 3 (16 lanes) and Intel offering Gen 5 (16 lanes).

Integrated graphics also differ: AMD uses Radeon Vega 6, Intel uses UHD Graphics 730. Release dates are distinct, with AMD launching on 2024-09-04 and Intel on 2024-01-07. The Intel part has a launch MSRP of $221. Transistor counts are listed for AMD (10,700 million) but are not specified for Intel.

Architecture Differences

The architectural split is fundamental. The AMD Ryzen 3 PRO 5355G is built on Zen 3 architecture, codenamed Cezanne, from the 5000 series. It uses a 7 nm process from TSMC and integrates 10,700 million transistors on a 180 mm² die. The Intel Core i5-14400T is built on Raptor Lake architecture, codenamed Raptor Lake-R, from the Core 14th Gen series. It uses a 10 nm process from Intel and has a 215 mm² die, though transistor count is not listed.

The core count difference reflects divergent design philosophies. AMD’s 4-core/8-thread configuration with a 4.00 GHz base clock prioritizes high frequency per core. Intel’s 10-core/16-thread configuration with a 1.50 GHz base clock prioritizes raw parallelism, relying on boost to 4.50 GHz for single-thread performance. The L3 cache difference is substantial: Intel’s 20 MB shared L3 is 2.5 times larger than AMD’s 8 MB.

Memory architecture differs in flexibility. AMD is restricted to DDR4, while Intel supports both DDR4 and DDR5, allowing for a broader range of platform configurations. PCIe generation also differs, with Intel offering Gen 5 versus AMD’s Gen 3, which affects available bandwidth for expansion cards and NVMe storage.

Both CPUs share some traits: neither has an unlocked multiplier, both support ECC memory, both are for the desktop market segment, and both are currently active in production. The integrated graphics differ, with AMD’s Radeon Vega 6 and Intel’s UHD Graphics 730, though no benchmark data is provided for either iGPU. The release timing is also distinct, with Intel launching roughly eight months earlier.
