AMD Ryzen 5 40 vs Intel Core 3 305 Comparison

The benchmark database comparison between the AMD Ryzen 5 40 and the Intel Core 3 305 is decisive. The Intel Core 3 305 wins every single recorded head-to-head benchmark, 15 out of 15, with the AMD Ryzen 5 40 failing to secure a victory in any test. The Intel part also holds a higher average benchmark score of 18302 compared to the AMD’s 15882, and it sits in the 72nd percentile of all CPUs, four points above the AMD’s 70th percentile.

Head-to-Head Benchmarks

The largest performance gap appears in the PassMark find prime numbers test, where the Intel Core 3 305 scores 115 against the AMD Ryzen 5 40’s 20, a delta of -82.6% for the AMD part. This is the most extreme single-test disparity in the dataset, indicating a massive advantage for Intel in this integer-heavy workload.

Multi-core rendering also shows a severe split. In Cinebench R23 multi-core, the Intel Core 3 305 scores 13123 versus the AMD’s 4841, a -63.1% delta. The Cinebench R15 multi-core test tells a similar story: Intel scores 1322 while AMD manages 790, a -40.2% delta. Floating point math follows the same pattern, with Intel at 42284 and AMD at 15194, a -64.1% delta. The PassMark physics test shows Intel at 1233 versus AMD’s 432, a -65% delta, reinforcing the multi-threaded dominance.

Single-threaded results are also firmly in Intel’s favor, though the margins are smaller than in multi-core. Cinebench R23 single-core has Intel at 1852 and AMD at 1150, a -37.9% delta. PassMark single-thread shows Intel at 3977 and AMD at 2477, a -37.7% delta. Cinebench R15 single-core is the closest race in the entire set: Intel scores 186 against AMD’s 165.5, a -11% delta.

Some tests show a much tighter competition. PassMark integer math has Intel at 32295 and AMD at 31598, a -2.2% delta, the narrowest margin recorded. PassMark data compression is nearly as close, with Intel at 146857 and AMD at 141533, a -3.6% delta. These two results indicate that in specific integer and compression workloads, the AMD Ryzen 5 40 remains competitive despite the overall Intel lead.

The remaining tests fall in between. PassMark extended instructions shows Intel at 13543 versus AMD’s 6437, a -52.5% delta. PassMark data encryption has Intel at 11019 and AMD at 6646, a -39.7% delta. PassMark multithread shows Intel at 15439 and AMD at 9341, a -39.5% delta. PassMark random string sorting has Intel at 17623 and AMD at 15124, a -14.2% delta.

Where Each One Wins

The Intel Core 3 305 wins in every category measured, so the use-case split is defined by the magnitude of the advantage rather than by any AMD victory. The AMD Ryzen 5 40’s closest results are in PassMark integer math and data compression, where the delta is only -2.2% and -3.6% respectively. For workloads dominated by these operations, the two processors are near-parity, and the AMD part could be considered functionally equivalent in those specific tasks.

The Intel Core 3 305 is the clear choice for rendering, physics simulation, encryption, extended instruction sets, and prime number calculations. The deltas in these tests range from -37.9% to -82.6%, all favoring Intel. The Cinebench R23 multi-core result of 13123 versus 4841 is particularly significant for any application that scales across cores.

For single-threaded responsiveness, the Intel part also leads, with a 37.7% advantage in PassMark single-thread and a 37.9% advantage in Cinebench R23 single-core. The Cinebench R15 single-core delta of -11% is the smallest single-thread gap, but Intel still wins.

The AMD Ryzen 5 40 does not have a single recorded win, so no workload category can be assigned to it as a superior option. Its value lies only in the narrow margins of the integer and compression tests, where it nearly matches Intel.

Architecture Differences

The two processors come from different foundries and process nodes. The AMD Ryzen 5 40 uses a 6 nm process from TSMC, while the Intel Core 3 305 uses a 3 nm process from Intel. The AMD part is based on the Zen 2 architecture with the Mendocino codename, while the Intel part uses the Wildcat Lake codename.

Core and thread counts differ significantly. The AMD Ryzen 5 40 has 4 cores and 8 threads, while the Intel Core 3 305 has 6 cores and 6 threads. The AMD part relies on simultaneous multithreading to reach 8 threads, while the Intel part runs 6 threads across 6 physical cores.

Cache configurations are structured differently. The AMD Ryzen 5 40 has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 4 MB of shared L3 cache. The Intel Core 3 305 lists 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The Intel part has more total L3 cache, and its L2 cache is presented as a single aggregate figure rather than a per-core allocation.

Clock speeds are identical at the top end. Both parts boost to 4.30 GHz, but the AMD Ryzen 5 40 has a base clock of 2.80 GHz while the Intel Core 3 305 has a base clock of 1.50 GHz. Both are rated at a 15 W TDP.

Memory support diverges. The AMD Ryzen 5 40 supports LPDDR5 memory over a dual-channel bus with 88.0 GB/s of bandwidth. The Intel Core 3 305 supports DDR5 and LPDDR5X over a single-channel bus with 59.7 GB/s of bandwidth. The Intel part has a PCIe Gen 4 interface with 6 lanes, while the AMD part uses PCIe Gen 3 with 4 lanes.

Integrated graphics also differ. The AMD Ryzen 5 40 uses the Radeon 610M, while the Intel Core 3 305 uses Intel Xe3 Graphics with 1 Xe core. Neither processor supports ECC memory, and neither has an unlocked multiplier.

The Verdict

The data points to a single conclusion: the Intel Core 3 305 is the stronger processor across every benchmark recorded. Its 15-0 win record, combined with a higher average score of 18302 versus 15882 and a higher percentile ranking of 72 versus 70, leaves no ambiguity. For multi-core rendering, physics, encryption, and extended instruction workloads, the Intel part is substantially ahead, with deltas ranging from -37.9% to -82.6%.

The AMD Ryzen 5 40 cannot be recommended for performance-sensitive tasks based on this dataset. Its only competitive results are in PassMark integer math and data compression, where the deltas are -2.2% and -3.6%, but even there it loses. The AMD part does offer dual-channel memory with 88.0 GB/s of bandwidth versus the Intel part’s single-channel 59.7 GB/s, and it has a higher base clock of 2.80 GHz versus 1.50 GHz, but these specifications do not translate into any benchmark win.

The Intel Core 3 305 is the processor to select for users prioritizing raw performance, single-threaded speed, and rendering capability. The AMD Ryzen 5 40 is only relevant for workloads that resemble integer math or data compression, where the performance difference is negligible, but it remains the losing option in every measured test.
