Architecture Differences

The AMD Ryzen Embedded 8645HS uses the Zen 4 architecture under the codename Hawk Point. It is built on a 4 nm process node at TSMC, with 25,000 million transistors on a die size of 178 mm². The Intel Core 5 330 uses the Wildcat Lake codename and is built on a 3 nm process node at Intel. The Intel processor does not have listed transistor count or die size data in the database.

Cache hierarchies differ substantially. The AMD processor has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel processor has 192 KB of L1 cache total, 2.5 MB of L2 cache total, and 6 MB of shared L3 cache. The AMD part offers more L3 cache overall, while the Intel part has a larger aggregate L1 cache.

The memory controllers are distinct. AMD supports DDR5 only, with a dual-channel bus and 89.6 GB/s bandwidth, plus ECC support. Intel supports both DDR5 and LPDDR5X, but uses a single-channel bus with 59.7 GB/s bandwidth and no ECC support. This gives the AMD processor a clear advantage in memory throughput and reliability features.

PCIe connectivity also differs. The AMD Ryzen Embedded 8645HS provides Gen 4 with 20 lanes (CPU only), while the Intel Core 5 330 provides Gen 4 with 6 lanes (CPU only). The AMD part has more than three times the PCIe lane count.

Integrated graphics differ as well. The AMD part uses Radeon 760M graphics, while the Intel part uses Intel Xe3 Graphics with 2 Xe cores. The sockets are different: AMD Socket FP8 for the AMD chip and Intel BGA 1516 for the Intel chip. Both are mobile market segments, and both are active in production. The Intel part has a launch MSRP of $309.

The Verdict

The data shows a clear split between the two processors. The AMD Ryzen Embedded 8645HS is built for higher sustained performance with a 45 W TDP, 12 threads, dual-channel memory at 89.6 GB/s, and 20 PCIe Gen 4 lanes. It excels in multithreaded workloads and memory-heavy tasks. The Intel Core 5 330 is built for efficiency with a 15 W TDP, 6 threads, single-channel memory at 59.7 GB/s, and only 6 PCIe Gen 4 lanes.

Benchmark results from the database show the Intel Core 5 330 holds a 72nd percentile ranking among all CPUs, with an average benchmark score of 18345. Its nearest rivals include the Intel Core i3-14100 (delta 0.1%), Intel Core 7 360 (delta -0.2%), Intel Core i3-13100 (delta -0.2%), and Intel Core 3 305 (delta 0.2%). These deltas indicate the Intel Core 5 330 performs essentially on par with these four processors, with margins under 0.2%.

The AMD Ryzen Embedded 8645HS has no recorded benchmarks in the database, so its measured performance cannot be compared directly. However, its specifications suggest it targets workloads that benefit from higher thread counts and memory bandwidth. Users who prioritize multithreaded performance and memory throughput should look to the AMD part. Users who prioritize low power consumption and have lighter single-threaded tasks may find the Intel part sufficient, though its benchmark data shows it is competitive with mid-range Intel Core i3 parts.

Head-to-Head Benchmarks

The database contains benchmark results for the Intel Core 5 330 but none for the AMD Ryzen Embedded 8645HS. Therefore, the head-to-head comparison relies entirely on the Intel part's recorded scores and its position relative to other CPUs.

The Intel Core 5 330 achieves a Cinebench R23 multicore score of 13150 and a single-core score of 1856. In Cinebench R20, it scores 5523 multicore and 779 single-core. In Cinebench R15, it scores 1325 multicore and 186 single-core. These results show a consistent pattern of strong multicore performance relative to its class.

In PassMark tests, the Intel part scores 15471 in multithread, 4088 in single-thread, 33258 in integer math, 43885 in floating point math, 12808 in extended instructions, and 11076 in data encryption. It also scores 145287 in data compression, 17771 in random string sorting, 1201 in physics, and 114 in find prime numbers.

The average benchmark score for the Intel Core 5 330 is 18345. Its nearest rival, the Intel Core i3-14100, has an average score of 18318, which is 0.1% lower. The Intel Core 7 360 scores 18374, which is 0.2% higher. The Intel Core i3-13100 scores 18380, also 0.2% higher. The Intel Core 3 305 scores 18302, which is 0.2% lower. These narrow deltas indicate the Intel Core 5 330 sits squarely in a cluster of similar-performing CPUs.

Without benchmark data for the AMD Ryzen Embedded 8645HS, the database cannot provide a direct score comparison. The AMD part's specifications, however, indicate it should outperform the Intel part in multithreaded tasks due to its 12 threads versus 6 threads, higher boost clock of 5.00 GHz versus 4.60 GHz, and dual-channel memory at 89.6 GB/s versus single-channel at 59.7 GB/s.

Where Each One Wins

The AMD Ryzen Embedded 8645HS wins in scenarios that demand high thread counts and memory bandwidth. Its 12 threads and dual-channel memory at 89.6 GB/s make it suitable for parallel workloads such as compiling, rendering, and data processing. The 20 PCIe Gen 4 lanes provide ample connectivity for multiple peripherals or expansion devices. The 45 W TDP indicates it is designed for more substantial mobile or embedded systems that can accommodate higher power draw. ECC memory support adds reliability for data-sensitive applications.

The Intel Core 5 330 wins in scenarios that prioritize low power consumption. Its 15 W TDP is one-third of the AMD part's rating, making it suitable for fanless or battery-constrained designs. The 3 nm process node at Intel suggests a focus on efficiency. The launch MSRP of $309 provides a known price point for the Intel part, while the AMD part has no listed MSRP. The Intel part's benchmark scores show it performs on par with mid-range Intel Core i3 processors, making it a capable choice for general-purpose computing.

For single-threaded tasks, the Intel Core 5 330's boost clock of 4.60 GHz is close to the AMD part's 5.00 GHz, though the AMD part still holds an advantage on paper. The Intel part's single-thread score of 4088 in PassMark places it in a competitive range, but the AMD part's higher boost clock suggests it would win in this category if measured.

For memory-intensive workloads, the AMD part wins decisively with dual-channel bandwidth at 89.6 GB/s versus 59.7 GB/s. For low-power embedded applications, the Intel part wins with its 15 W TDP and support for LPDDR5X memory, which is often used in power-sensitive designs.

The database shows the Intel Core 5 330 fits into a performance tier alongside the Intel Core i3-14100, Core i3-13100, Core 7 360, and Core 3 305, all within 0.2% of each other. The AMD Ryzen Embedded 8645HS, with its higher TDP and thread count, targets a different segment where power is less constrained and performance per thread is prioritized.
