AMD Ryzen AI 5 PRO 340 vs Intel Core 3 305 Comparison

Head-to-Head Benchmarks

The benchmark records split almost evenly between these two mobile processors, with the AMD Ryzen AI 5 PRO 340 taking 8 wins and the Intel Core 3 305 taking 7. However, the margins tell a more nuanced story than the win count suggests.

The AMD chip's largest victory comes in PassMark integer math, where it scores 63,233 against Intel's 32,295, a massive 95.8% advantage. That result dominates the arithmetic-heavy workloads. Data compression also favors AMD heavily: 221,581 versus 146,857, a 50.9% lead. Random string sorting goes to AMD by 38.1% (24,334 versus 17,623), and multithread performance favors AMD by 24.5% (19,215 versus 15,439). In Cinebench R15, AMD wins multicore by 31.8% (1,743 versus 1,322) and singlecore by 48.4% (276 versus 186). Extended instructions go AMD's way by 16.1% (15,721 versus 13,543), and data encryption is a narrow AMD win, 11,212 versus 11,019, a 1.8% edge.

The Intel Core 3 305 counters with Cinebench R23 multicore, scoring 13,123 against AMD's 11,534, a 12.1% advantage. That is a notable reversal from the R15 result. Intel also wins Cinebench R23 singlecore, 1,852 versus 1,802, a 2.7% lead. PassMark single-thread tests go Intel's way at 3,977 versus 3,758, a 5.5% margin. Prime number finding is Intel's best relative result: 115 versus 74, a 35.7% lead. Floating point math favors Intel by 6.2% (42,284 versus 39,662), and physics simulation goes Intel's way by 12.1% (1,233 versus 1,084).

The overall average benchmark score underscores the split. AMD's average sits at 27,932, placing it in the 80th percentile of all CPUs. Intel's average is 18,302, which lands in the 72nd percentile. AMD's nearest rivals include the AMD Ryzen 7 5800X3D (0.1% ahead), AMD Ryzen 7 6800U (0.2% ahead), and Intel Core i9-10900K (0.2% ahead), while the Intel Core i9-12900H trails by 0.3%. Intel's nearest rivals are the Intel Core i3-14100 (0.1% ahead), Intel Core 5 330 (0.2% ahead), and Intel Core 7 360 (0.4% ahead), with the AMD Ryzen 5 2600E trailing by 0.4%.

Where Each One Wins

The AMD Ryzen AI 5 PRO 340 delivers its strongest results in workloads that scale with thread count and integer throughput. The 12 threads versus Intel's 6 threads give it a clear structural edge in Cinebench R15 multicore, PassMark multithread, integer math, compression, and sorting. The data shows a consistent pattern: AMD wins every test that involves heavy parallel integer operations or data movement. The 50.9% compression advantage and 95.8% integer math lead are the two largest gaps in the entire comparison, so any application that compresses files, processes large datasets, or runs parallel integer code will see a substantial benefit from the AMD part.

The Intel Core 3 305 wins where single-thread efficiency and certain specialized instructions matter more. Its Cinebench R23 multicore win is curious given the thread deficit, but the R23 result suggests the Intel cores sustain higher throughput under that specific rendering workload. The 35.7% lead in prime number finding indicates strong performance on integer-heavy sequential loops. Floating point math, physics simulation, and single-thread tests all favor Intel, which points to a well-optimized core design for scalar and FP-heavy tasks. The R23 singlecore margin is small at 2.7%, but the PassMark single-thread margin of 5.5% reinforces the pattern.

The use-case split is straightforward. For content creation involving rendering in Cinebench R23, physics simulation, or floating point math, Intel holds the edge. For database work, file compression, encryption, sorting, and any multithreaded integer workload, AMD is clearly ahead. The R15 versus R23 multicore discrepancy is worth noting: AMD wins R15 by 31.8%, Intel wins R23 by 12.1%. That suggests the two processors respond differently to the rendering engine versions, so the choice depends on which Cinebench version matches the actual production workload.

Specification Differences

The core and thread counts differ significantly. Both have 6 cores, but the AMD Ryzen AI 5 PRO 340 has 12 threads while the Intel Core 3 305 has only 6 threads. Clock speeds favor AMD: 2.00 GHz base and 4.80 GHz boost versus Intel's 1.50 GHz base and 4.30 GHz boost. Thermal design power also differs, with AMD rated at 28W and Intel at 15W.

Memory configuration separates the two clearly. AMD uses a dual-channel memory bus with 89.6 GB/s bandwidth and supports ECC memory. Intel uses a single-channel bus with 59.7 GB/s bandwidth and does not support ECC. Both support DDR5 and LPDDR5X memory types.

PCIe lanes differ as well. AMD provides Gen 4 with 16 CPU-only lanes, while Intel provides Gen 4 with 6 CPU-only lanes. The integrated graphics units differ: AMD uses a Radeon 840M, Intel uses Intel Xe3 Graphics with 1 Xe core. The sockets are different: AMD Socket FP8 for AMD, Intel BGA 1516 for Intel. The AMD part number is 100-000001600, and the Intel part number is SAE3L. Neither processor has an unlocked multiplier.

Architecture Differences

The AMD Ryzen AI 5 PRO 340 uses the Zen 5 architecture under the Krackan Point codename, part of the Ryzen AI PRO 300 generation that combines Zen 5 and Zen 5c cores. It is built on a 4 nm process at TSMC with a die size of 195 mm². The cache layout includes 80 KB L1 per core, 1 MB L2 per core, and 8 MB L3.

The Intel Core 3 305 uses the Wildcat Lake codename from the Core 3 generation. It is built on a 3 nm process at Intel with no die size recorded. The cache layout is different: 192 KB L1 total, 2.5 MB L2 total, and 6 MB shared L3.

The cache structures reflect the different design philosophies. AMD's per-core L1 and L2 allocation favors its 12-thread configuration, while Intel's shared L3 and larger total L1 (192 KB versus 80 KB per core, though AMD's 80 KB is per core) suit a lower-thread design. The process node advantage goes to Intel at 3 nm versus AMD's 4 nm, but the performance data shows AMD still holds the overall average score lead.

The memory controllers differ in channel count, which affects bandwidth. AMD's dual-channel design provides 89.6 GB/s, while Intel's single-channel design provides 59.7 GB/s. ECC support is present on AMD but absent on Intel, making the AMD part more suitable for error-sensitive workloads. The PCIe lane count also differs: 16 lanes on AMD versus 6 lanes on Intel, which affects expansion capability for GPUs or NVMe drives.

The integrated graphics differ in architecture. AMD uses the Radeon 840M, while Intel uses Xe3 Graphics with a single Xe core. The database does not include graphics benchmarks, so relative GPU performance cannot be assessed from the recorded data.

The Verdict

The benchmark data points to the AMD Ryzen AI 5 PRO 340 for users who prioritize multithreaded integer performance, data compression, encryption, and sorting. The 24.5% multithread lead, 50.9% compression lead, and 95.8% integer math lead make it the clear choice for database workloads, file archiving, and parallel processing tasks. The dual-channel memory bus with 89.6 GB/s bandwidth and 16 PCIe lanes also give it a structural advantage for memory-heavy and expansion-heavy mobile systems. The 80th percentile ranking versus Intel's 72nd reinforces the overall performance lead.

The Intel Core 3 305 suits workloads that depend on single-thread speed, floating point math, and prime number calculations. Its 5.5% single-thread lead and 35.7% prime number lead indicate strong scalar performance. The 15W TDP makes it a lower-power option compared to AMD's 28W rating, which matters for fanless or ultraportable designs. The R23 multicore win of 12.1% shows that in certain rendering scenarios, the Intel part can outperform despite having half the threads. The 3 nm process node also gives Intel a manufacturing advantage.

The choice depends on the workload mix. AMD wins 8 of the 15 head-to-head benchmark comparisons, and its wins include some of the largest margins in the entire comparison. Intel wins 7, but several are narrow. The average benchmark score difference is substantial: 27,932 versus 18,302, a difference of 9,630 points. The AMD part's nearest rivals include desktop-class processors like the Ryzen 7 5800X3D and Core i9-10900K, while Intel's nearest rivals are lower-tier mobile and desktop parts like the Core i3-14100 and Ryzen 5 2600E. That positioning alone tells most of the story. For raw throughput across a broad range of tasks, the AMD Ryzen AI 5 PRO 340 is the stronger processor. For specific single-thread and FP-heavy workloads in a lower-power envelope, the Intel Core 3 305 has its place.
