Where Each One Wins

The benchmark data splits the two processors evenly in head-to-head comparisons, with each winning two tests. However, the nature of those wins reveals distinct use-case strengths.

The AMD Ryzen 5 6600HS wins in Cinebench R15 both multi-core and single-core. In R15 multi-core, it scores 1656 against 1121 for the Intel part, a 47.7 percent advantage. In R15 single-core, it scores 235 against 158, a 48.7 percent advantage. These are older benchmark tests that tend to favor lower-latency, higher-clock-speed cores. The AMD part has a base clock of 3.30 GHz and a boost clock of 4.50 GHz, which explains its dominance in these latency-sensitive workloads. For tasks that rely on quick responses from a single thread or a small number of threads, the AMD Ryzen 5 6600HS is clearly the stronger choice.

The Intel Atom P5342 wins in Cinebench R23 both multi-core and single-core. In R23 multi-core, it scores 11122 against 9131 for the AMD part, a 17.9 percent advantage. In R23 single-core, it scores 1570 against 1465, a 6.7 percent advantage. The R23 tests are newer and more demanding, particularly in multi-core scenarios that can scale across many threads. The Intel part's 16 physical cores allow it to sustain higher throughput in heavily parallel workloads. The single-core win in R23 is notable because it shows the Tremont cores, despite lower clocks, can outperform the Zen 3+ core in this specific test.

The split results suggest that the AMD Ryzen 5 6600HS is better suited for older or lighter workloads where single-thread latency matters most, while the Intel Atom P5342 is better suited for modern, heavily threaded applications that can use all 16 of its cores. The Intel part also benefits from its 71 watt TDP, which gives it more power headroom than the 35 watt AMD part.

For mobile users who need a responsive system for everyday tasks, the AMD part's high boost clock and strong R15 scores indicate an advantage. For server or workstation workloads that are designed to scale across many cores, the Intel part's R23 multi-core score suggests it can handle sustained parallel processing more effectively.

The largest win for the AMD Ryzen 5 6600HS comes in Cinebench R15 single-core. The AMD part scores 235, while the Intel Atom P5342 scores 158. This is a 48.7 percent difference, making it the largest performance gap in either direction. The AMD part's boost clock of 4.50 GHz likely drives this result, as single-core tests depend heavily on maximum clock speed rather than core count. The R15 multi-core test also favors AMD, with a score of 1656 versus 1121 for Intel, a 47.7 percent difference. This shows that even in a multi-core scenario, the AMD part's six faster cores with 12 threads can outperform Intel's 16 slower cores in this particular test.

The Intel Atom P5342 wins Cinebench R23 multi-core by a substantial margin. The Intel part scores 11122, while the AMD Ryzen 5 6600HS scores 9131. This is a 17.9 percent advantage for Intel. The R23 multi-core test is more demanding and can take advantage of the Intel part's 16 physical cores. The fact that Intel wins this test despite having no boost clock and a lower base clock of 2.20 GHz indicates that the workload scales effectively across many cores. The Intel part also wins Cinebench R23 single-core with a score of 1570 versus 1465 for AMD, a 6.7 percent advantage. This is a notable result because it shows the Tremont architecture can outperform Zen 3+ in this specific single-threaded test, despite the AMD part having a much higher boost clock.

The average benchmark scores reflect this split. The Intel Atom P5342 has an average score of 3217, while the AMD Ryzen 5 6600HS has an average score of 3122. The Intel part's nearest rivals include the AMD Ryzen 3 PRO 5350GE and AMD Ryzen 7 4800U, both with average scores of 3218 and a delta of 0 percent, as well as the Intel Core i5-1240P at 3202 and the Intel Core i3-13100T at 3198.

The overall win count is even at two each. However, the magnitude of AMD's wins in R15 is larger than the magnitude of Intel's wins in R23. AMD's R15 multi-core win is 47.7 percent, and its R15 single-core win is 48.7 percent. Intel's R23 multi-core win is 17.9 percent, and its R23 single-core win is 6.7 percent. If a user places more weight on the R15 tests, the AMD part appears stronger. If a user places more weight on the R23 tests, the Intel part appears stronger.

The Verdict

The data presents a clear choice based on workload type and platform requirements.

The AMD Ryzen 5 6600HS is the better choice for mobile platforms where power efficiency matters. Its 35 watt TDP is less than half of the Intel Atom P5342's 71 watt TDP. It includes Radeon 660M integrated graphics, so no discrete GPU is required. It supports DDR5 memory with 76.8 GB/s bandwidth, nearly double the Intel part's DDR4 bandwidth of 42.7 GB/s. Its boost clock of 4.50 GHz gives it a decisive edge in Cinebench R15 tests, where it outperforms the Intel part by nearly 49 percent in single-core. Users who run older software, latency-sensitive applications, or workloads that do not scale beyond a handful of threads will find the AMD part significantly faster. The lack of ECC support and the Mobile market segment classification confirm that this is not a server part.

The Intel Atom P5342 is the better choice for server or workstation environments where many threads and ECC memory are required. Its 16 physical cores deliver a 17.9 percent advantage over the AMD part in Cinebench R23 multi-core, the most demanding test in the dataset. It supports ECC memory, which is essential for data integrity in server workloads. Its 71 watt TDP, while higher, is acceptable in a chassis designed for continuous operation. The lack of integrated graphics is not a drawback in a server context where a discrete GPU is assumed. Its release date of June 5, 2022, and its recorded launch MSRP of $708 position it as a specific-purpose part for edge computing and network infrastructure. Users who run modern, heavily threaded workloads will find the Intel part faster in R23 tests.

The even split in head-to-head wins means the verdict depends entirely on the use case. For a mobile workstation or high-end laptop, the AMD Ryzen 5 6600HS offers superior single-thread performance, integrated graphics, lower power draw, and faster memory. For a server appliance or embedded system, the Intel Atom P5342 offers more cores, ECC support, and better performance in the newest Cinebench multi-core test. The database records both as Active production parts, so either can be sourced for new designs. The choice hinges on whether the workload favors the AMD part's R15 wins or the Intel part's R23 wins.
