Architecture Differences

The AMD Ryzen Embedded 8645HS and Intel Core 3 305 diverge significantly in their internal designs. The AMD chip uses the Zen 4 architecture under the Hawk Point codename, part of the 8000 series Ryzen Embedded family. It is built on a 4 nm process at TSMC, with 25,000 million transistors on a 178 mm² die. The Intel chip uses the Wildcat Lake codename under the Core 3 generation and is fabricated on Intel's 3 nm process. The database does not list transistor count or die size for the Intel part.

Cache organization differs sharply. The AMD processor allocates 64 KB of L1 cache per core and 1 MB of L2 cache per core, with 16 MB of shared L3 cache. The Intel processor lists 192 KB of L1 cache total, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The AMD design provides substantially more L3 capacity, which can benefit workloads that repeatedly access a large working set.

Clock speeds tell a different story. The AMD part runs at a 4.30 GHz base clock and boosts to 5.00 GHz. The Intel part runs at a much lower 1.50 GHz base clock and boosts to 4.30 GHz. The thermal design power reflects this: the AMD processor is rated at 45 W, while the Intel processor is rated at 15 W. This suggests the Intel chip targets lower power envelopes, while the AMD chip aims for higher sustained performance.

Memory architecture also separates the two. The AMD processor supports dual-channel DDR5 with 89.6 GB/s of bandwidth. The Intel processor supports single-channel DDR5 and LPDDR5X with 59.7 GB/s of bandwidth. ECC memory is supported on the AMD side only. PCIe connectivity differs as well: the AMD processor provides 20 Gen 4 lanes, while the Intel processor provides 6 Gen 4 lanes.

Integrated graphics differ in branding and structure. The AMD processor includes a Radeon 760M, while the Intel processor includes Intel Xe3 Graphics with 1 Xe core. Both are mobile-market parts, but the database does not provide comparative graphics benchmarks.

The Intel processor has a launch MSRP of $309. The AMD processor has no launch MSRP listed. The AMD part was released on 2024-04-01, while the Intel part was released on 2026-04-15.

The Verdict

The data supports a clear split based on workload and power constraints. The Intel Core 3 305 is the only part with measured performance, and its scores place it within 0.4 percent of several close rivals. Its 15 W TDP and single-channel memory controller indicate a design focused on efficiency and compact systems. Its 6 threads and 6 MB of L3 cache suggest it handles typical productivity tasks adequately, but the absence of simultaneous multithreading limits heavy parallel workloads.

The AMD Ryzen Embedded 8645HS offers 12 threads, a 5.00 GHz boost clock, 16 MB of L3 cache, dual-channel memory at 89.6 GB/s, ECC support, and 20 PCIe Gen 4 lanes. Those specifications point to a part intended for embedded applications that need more memory bandwidth, more PCIe connectivity, and error-correcting memory. The 45 W TDP indicates a higher power budget is acceptable.

Benchmark results for the AMD part are absent, so the verdict cannot claim measured superiority. The Intel part demonstrates competitive single-thread performance with a Cinebench R23 single-core score of 1,852 and a PassMark single-thread score of 3,977. For users who need measured data and low power draw, the Intel Core 3 305 is the only option with recorded results. For users who need 12 threads, ECC memory, dual-channel bandwidth, and more PCIe lanes, the AMD Ryzen Embedded 8645HS offers those specifications on paper.

Where Each One Wins

The Intel Core 3 305 wins in measured performance data. It has 17 benchmark results, an average score of 18,302, and a percentile rank of 72. Its Cinebench R23 multi-core score of 13,123 and PassMark multithread score of 15,439 show what the silicon can actually do. The 15 W TDP gives it a clear advantage in power-constrained designs, and the single-channel memory controller reduces board complexity. The launch MSRP of $309 provides a fixed reference point for procurement teams, though pricing comparisons are not covered here.

The AMD Ryzen Embedded 8645HS wins on specification breadth. It offers 12 threads versus 6, a 5.00 GHz boost clock versus 4.30 GHz, 16 MB of L3 versus 6 MB, dual-channel memory bandwidth of 89.6 GB/s versus 59.7 GB/s, ECC memory support, and 20 PCIe Gen 4 lanes versus 6. Those features matter for embedded workloads that move large data sets, require memory integrity, or need to attach multiple Gen 4 devices. The 45 W TDP is higher, but the database shows no power-efficiency benchmark to penalize it directly.

The Cinebench and PassMark numbers for the Intel part suggest it can handle single-threaded tasks well: the R23 single-core score of 1,852 and the PassMark single-thread score of 3,977 are respectable for a 15 W part. The data compression score of 146,857 and floating point math score of 42,284 indicate solid throughput for those specific operations. The AMD part has no such measurements, so its real-world performance cannot be confirmed from the database.

The choice between the two depends on whether measured results or listed capabilities matter more. The Intel Core 3 305 is the only one with proof of performance in the database. The AMD Ryzen Embedded 8645HS presents a stronger feature sheet for applications that need more threads, more memory bandwidth, ECC, and more PCIe connectivity.
