AMD Ryzen 3 PRO 5355GE vs Intel Core 3 305 Comparison

AMD Ryzen 3 PRO 5355GE and Intel Core 3 305 are both active processors, but they target different segments: the Ryzen is a 35W desktop chip on Socket AM4, while the Core 3 is a 15W mobile part on BGA 1516. The benchmark data shows a decisive overall victory for the Intel Core 3 305, which wins 15 of the 17 head-to-head tests, but the AMD chip claims two notable wins in workloads where its architecture holds a clear advantage. This analysis breaks down the recorded scores, the architectural reasons behind them, and the use cases that favor each processor.

Head-to-Head Benchmarks

The Intel Core 3 305 dominates the multi-threaded and single-threaded rendering tests. In Cinebench R23, the Intel chip scores 13,123 in multi-core versus 10,846 for the AMD Ryzen, a delta of -17.4% in favor of Intel. The gap is consistent across older Cinebench versions: R20 multi-core shows 5,511 for Intel against 4,555 for AMD (-17.3%), and R15 multi-core shows 1,322 versus 1,093 (-17.3%). The single-core results follow the same pattern. Cinebench R23 single-core gives Intel 1,852 points against AMD’s 1,531 (-17.3%), R20 single-core gives 777 versus 643 (-17.2%), and R15 single-core gives 186 versus 154 (-17.2%). The Intel part is uniformly about 17% ahead in these CPU-bound tests.

The PassMark suite reveals a more varied picture. Intel wins the multithread test with 15,439 against 12,761 (-17.3%), matching the Cinebench margin. The single-thread PassMark test shows Intel at 3,977 versus 3,089 (-22.3%), a larger lead than in Cinebench. Intel also wins heavily in floating-point math, scoring 42,284 against AMD’s 24,115 (-43%), and in physics, 1,233 versus 552 (-55.2%). The find prime numbers test is a massive Intel victory: 115 versus 31 (-73%), the largest percentage gap in the entire data set. Extended instructions also favor Intel, 13,543 versus 10,368 (-23.4%), and data encryption goes to Intel, 11,019 versus 9,564 (-13.2%). Random string sorting is close, with Intel at 17,623 and AMD at 17,255 (-2.1%).

The AMD Ryzen 3 PRO 5355GE has two wins. Integer math is the standout: AMD scores 44,665 against Intel’s 32,295, a delta of +38.3% in AMD’s favor. This is the largest win for either side in percentage terms. The other AMD win is data compression, 152,885 versus 146,857 (+4.1%). These two results show that the Ryzen’s core design is highly efficient in specific integer-heavy and compression workloads, despite losing the broader multithread tests by 17-22%.

Overall, the Intel Core 3 305 wins 15 of 17 tests, with the average benchmark score confirming the trend: Intel at 18,302 versus AMD at 17,482. The Intel part sits at the 72nd percentile of all CPUs, while the AMD part is at the 71st. The nearest rival data reinforces this. The Intel Core 3 305 is within 0.4% of the AMD Ryzen 5 2600E (18,230) and within 0.2% of the Intel Core 5 330 (18,345). The AMD Ryzen 3 PRO 5355GE is within 0.9% of the AMD Ryzen 5 4500 (17,333) and 0.5% of the Intel Core 7 150U (17,395). The Intel chip’s average score is 4.7% higher than the AMD chip’s, a margin that matches the head-to-head results.

The Verdict

The data points to the Intel Core 3 305 as the stronger processor for almost all measured workloads. It leads in every Cinebench test, all PassMark tests except two, and its average score is higher. The single-thread performance is particularly notable: Intel leads by 22.3% in PassMark single-thread and by 17.2-17.3% in all Cinebench single-core tests. This makes the Intel part the clear choice for tasks that depend on per-core speed, such as lightly threaded applications and responsive general computing.

The AMD Ryzen 3 PRO 5355GE has a narrow but real niche. Its 38.3% lead in integer math and 4.1% lead in data compression indicate strong performance in specific calculation and data-handling workloads. However, these two wins do not offset the Intel part’s dominance elsewhere. The AMD chip loses the multithread tests by 17.3-17.4% and the floating-point tests by 43%, which limits its appeal for rendering, physics simulation, or any task that scales with FPU throughput.

The market segment difference is critical. The Intel Core 3 305 is a mobile processor with a 15W TDP, while the AMD Ryzen 3 PRO 5355GE is a desktop processor with a 35W TDP. Despite the higher power envelope, the AMD chip fails to match the Intel part in most benchmarks. The Intel part achieves its superior scores at lower power, which is a decisive factor for mobile systems. The AMD part’s only advantage is its two specific workload wins, which do not translate into a general performance lead.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen 3 PRO 5355GE is built on TSMC’s 7 nm process and uses the Zen 3 architecture, codenamed Cezanne. It has 4 cores and 8 threads, with a base clock of 3.60 GHz and a boost clock of 4.20 GHz. The L1 cache is 64 KB per core, L2 is 512 KB per core, and L3 is 8 MB total. The chip uses DDR4 memory in dual-channel mode with 51.2 GB/s bandwidth and supports ECC memory. It has 16 PCIe Gen 3 lanes from the CPU and integrates Radeon Vega 6 graphics. The die size is 180 mm² with 10,700 million transistors.

The Intel Core 3 305 uses Intel’s 3 nm process with the Wildcat Lake codename. It has 6 cores and 6 threads, meaning it lacks simultaneous multithreading. The base clock is 1.50 GHz, but the boost clock reaches 4.30 GHz, higher than the AMD chip’s 4.20 GHz. The cache layout is different: L1 is 192 KB (not per-core), L2 is 2.5 MB, and L3 is 6 MB shared. It supports DDR5 and LPDDR5X memory in single-channel mode with 59.7 GB/s bandwidth. ECC memory is not supported. The PCIe interface is Gen 4 with 6 lanes from the CPU, and the integrated graphics is Intel Xe3 Graphics with 1 Xe core.

The core and thread count difference is significant. The AMD chip has 4 cores and 8 threads, while the Intel chip has 6 cores and 6 threads. The Intel part uses more physical cores but no hyper-threading, while the AMD part uses fewer cores with simultaneous multithreading. The benchmark results show that the Intel chip’s 6 physical cores win the multithread tests by about 17%, despite the AMD chip’s thread advantage. The single-thread results show the Intel chip’s higher boost clock (4.30 GHz versus 4.20 GHz) and newer architecture yield a 17-22% lead.

The memory subsystem differs substantially. The AMD chip uses dual-channel DDR4, while the Intel chip uses single-channel DDR5/LPDDR5X. Despite having one channel, the Intel part’s memory bandwidth is higher at 59.7 GB/s versus 51.2 GB/s. The process node advantage is also clear: Intel’s 3 nm versus TSMC’s 7 nm. The Intel chip integrates fewer PCIe lanes (6 versus 16), but they are Gen 4 versus Gen 3. The Intel part also lacks ECC support, which the AMD part provides.

Where Each One Wins

The Intel Core 3 305 wins in rendering and compute-heavy workloads. All three Cinebench versions (R15, R20, R23) show Intel ahead by 17.2-17.4% in both single-core and multi-core tests. The PassMark multithread test confirms this, with Intel at 15,439 versus 12,761 (-17.3%). Intel also wins the PassMark single-thread test by 22.3%, making it the better choice for applications that depend on high per-core performance. The floating-point math result (42,284 versus 24,115, -43%) and the physics test (1,233 versus 552, -55.2%) show Intel’s strength in FPU-intensive tasks. The find prime numbers test is a massive Intel win (115 versus 31, -73%), indicating a strong integer unit for certain algorithms. Extended instructions (13,543 versus 10,368, -23.4%) and data encryption (11,019 versus 9,564, -13.2%) also go to Intel.

The AMD Ryzen 3 PRO 5355GE wins in two specific areas. The integer math score of 44,665 versus 32,295 (+38.3%) is the largest win in the comparison. This suggests AMD’s Zen 3 cores have a substantial advantage in pure integer arithmetic operations. The data compression score of 152,885 versus 146,857 (+4.1%) shows a smaller but clear lead. These two wins indicate the AMD chip is suited for workloads that are heavily integer-based or involve data compression algorithms, such as certain database operations or file archiving. However, these are isolated victories in a data set where Intel wins 15 of 17 tests.
