AMD Ryzen 7 PRO 8840U vs Intel Core 3 305 Comparison

The Verdict

The benchmark data presents a clear hierarchy between these two mobile processors. The AMD Ryzen 7 PRO 8840U wins 13 of the 17 recorded head-to-head comparisons, while the Intel Core 3 305 takes 4 wins. The AMD part holds a decisive lead across almost every multi-threaded and memory-sensitive workload. Its average benchmark score of 32233 places it in the 83rd percentile of all CPUs, while the Intel Core 3 305 averages 18302, sitting in the 72nd percentile. For workloads that scale with core count, memory bandwidth, or sustained throughput, the Ryzen 7 PRO 8840U is the stronger choice. The Intel Core 3 305, however, demonstrates superior results in single-thread integer-style PassMark tests, prime number finding, and physics simulations, making it the better option for those specific narrow workloads. The data does not support a general recommendation for the Intel part outside of those niches.

Architecture Differences

The AMD Ryzen 7 PRO 8840U is built on the Zen 4 architecture, codenamed Hawk Point, using TSMC's 4 nm process node. It integrates 8 cores and 16 threads, with a base clock of 3.30 GHz and a boost clock of 5.10 GHz. The thermal design power is 28 W. The chip contains 25,000 million transistors on a 178 mm² die. Cache is organized as 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. Memory support includes DDR5 over a dual-channel bus, delivering a memory bandwidth of 89.6 GB/s. ECC memory is supported. PCIe connectivity is Gen 4 with 20 lanes from the CPU. The integrated graphics are Radeon 780M. The socket is AMD Socket FP7.

The Intel Core 3 305, codenamed Wildcat Lake, uses Intel's 3 nm process node. It provides 6 cores and 6 threads, with a base clock of 1.50 GHz and a boost clock of 4.30 GHz. The thermal design power is 15 W. Cache totals 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. Memory support covers DDR5 and LPDDR5X over a single-channel bus, yielding a memory bandwidth of 59.7 GB/s. ECC memory is not supported. PCIe connectivity is Gen 4 with 6 lanes from the CPU. The integrated graphics are Intel Xe3 Graphics with 1 Xe core. The socket is Intel BGA 1516. The launch MSRP for the Intel part is $309.

The architectural contrasts are substantial. The AMD chip has two more cores, ten more threads, and roughly 50% more L3 cache. Its memory bus is dual-channel versus single-channel, and its bandwidth advantage is 89.6 GB/s versus 59.7 GB/s. The Intel part has a higher process node count at 3 nm versus 4 nm, but the measurable performance difference does not favor it. The AMD chip also has a much higher boost clock, 5.10 GHz versus 4.30 GHz, and a higher base clock, 3.30 GHz versus 1.50 GHz. The Intel part consumes less power on paper, 15 W versus 28 W, which may matter for fanless or ultra-light designs, but the recorded benchmark scores do not translate that efficiency into performance wins.

Where Each One Wins

The AMD Ryzen 7 PRO 8840U dominates nearly every category in the recorded data. In Cinebench tests, it wins all six variants: R15 multicore, R15 singlecore, R20 multicore, R20 singlecore, R23 multicore, and R23 singlecore. The margins are consistent, ranging from 54.3% to 54.8% across those tests. In PassMark workloads, the AMD part wins data compression, data encryption, extended instructions, floating point math, integer math, multithread, and random string sorting. The integer math result is especially pronounced, with a 173.5% advantage over the Intel chip. Random string sorting shows an 87.9% lead, and data compression shows an 85.7% lead. These results indicate that the AMD part is the preferred choice for compression, encryption, sorting, integer-heavy computation, and general multithreaded productivity.

The Intel Core 3 305 wins four recorded comparisons. It takes passmark_find_prime_numbers with a score of 115 versus 76, a 33.9% advantage. It wins passmark_physics with 1233 versus 1174, a 4.8% edge. It also wins passmark_single_thread (and the duplicate passmark_singlethread entry) with 3977 versus 3641, an 8.4% advantage. These wins suggest that the Intel part handles certain single-threaded integer workloads and physics simulations better, despite having fewer cores and a lower boost clock. The single-thread PassMark score is notable because it runs counter to the Cinebench single-core results, where the AMD part leads by 54.4% to 54.8%. This divergence likely reflects different instruction-level behaviors in the two benchmark suites, but the recorded data does not explain the cause beyond what is listed.

Head-to-Head Benchmarks

The largest single win for the AMD Ryzen 7 PRO 8840U comes in passmark_integer_math, where it scores 88339 against the Intel Core 3 305's 32295. That is a 173.5% advantage, the biggest delta in the entire comparison. The AMD part also posts enormous margins in passmark_random_string_sorting (33109 versus 17623, an 87.9% lead) and passmark_data_compression (272664 versus 146857, an 85.7% lead). These three workloads, all heavily dependent on memory throughput and parallel execution, illustrate the practical impact of the AMD chip's 8 cores, 16 threads, and dual-channel memory bus.

The Cinebench results are uniformly lopsided. In Cinebench R23 multicore, the AMD part scores 20254 versus 13123, a 54.3% lead. Cinebench R23 singlecore shows 2859 versus 1852, a 54.4% lead. Cinebench R20 multicore delivers 8506 versus 5511, a 54.3% lead, and Cinebench R20 singlecore delivers 1200 versus 777, a 54.4% lead. Cinebench R15 multicore gives 2041 versus 1322, a 54.4% lead, and Cinebench R15 singlecore gives 288 versus 186, a 54.8% lead. The consistency of these margins, all clustered around 54% to 55%, suggests a systematic advantage rather than a workload-specific quirk.

The PassMark multithread test reinforces the same story. The AMD part scores 23850 versus 15439, a 54.5% lead. PassMark data encryption shows 16441 versus 11019, a 49.2% lead. Extended instructions come in at 19132 versus 13543, a 41.3% lead. Floating point math shows a smaller but still clear margin: 50746 versus 42284, a 20% lead.

The Intel Core 3 305's wins are narrower in absolute terms. Its best result is passmark_find_prime_numbers, where it scores 115 against the AMD part's 76, a 33.9% advantage. That is the only Intel win with a double-digit margin. The other three wins are much closer. Passmark_physics gives Intel 1233 versus 1174, a 4.8% edge. The two single-thread PassMark entries, passmark_single_thread and passmark_singlethread, both show 3977 versus 3641, an 8.4% lead for Intel.

The overall win count is 13 for the AMD Ryzen 7 PRO 8840U and 4 for the Intel Core 3 305. The percentile placement reflects that split: 83rd percentile for AMD, 72nd for Intel. The nearest rivals in the database for the AMD part are the Intel Core i9-11900 (average score 32226, 0% delta), Intel Core i5-14400F (32279, -0.1%), Intel Core i7-12800H (32121, 0.3%), and Intel Core i5-14400 (32115, 0.4%). The Intel Core 3 305 sits closest to the Intel Core i3-14100 (18318, -0.1%), Intel Core 5 330 (18345, -0.2%), Intel Core 7 360 (18374, -0.4%), and AMD Ryzen 5 2600E (18230, 0.4%).
