AMD Ryzen Embedded 8640U vs Intel Core 9 273PQE Comparison

AMD Ryzen Embedded 8640U and Intel Core 9 273PQE occupy different corners of the processor market, one a compact mobile part for embedded systems, the other a high-core-count desktop processor for demanding workloads. The database places the AMD part at the 50th percentile among all CPUs, while the Intel chip sits at the 93rd percentile, a gap that reflects their different design targets and performance ceilings.

The Verdict

The Intel Core 9 273PQE is the clear choice for compute-heavy desktop workloads. Its 12 cores and 24 threads double the AMD Ryzen Embedded 8640U’s 6 cores and 12 threads, and the recorded benchmark data confirms a substantial performance advantage in multithreaded tasks. The Intel part’s average benchmark score of 66099 places it near the top of the database, just 0.1% behind the Intel Core Ultra 5 250KF Plus and 0.3% ahead of the AMD Ryzen 9 7950X3D. It also outscores the AMD EPYC 4465P by 1.2% and the Intel Core Ultra 5 250K Plus by 1.1%. For users running rendering, compilation, scientific simulation, or any workload that scales across cores, the Intel processor delivers roughly three times the multithreaded throughput in Cinebench tests.

The AMD Ryzen Embedded 8640U serves a different purpose. It is built for power-constrained embedded systems, mobile devices, and industrial applications where space and thermal limits matter more than raw core counts. Its 28 watt TDP versus the Intel part’s 125 watt TDP shows a clear efficiency orientation. The AMD chip uses a 4 nm process from TSMC, while the Intel processor uses a 10 nm process from Intel’s own fabs. The AMD part’s integrated Radeon 760M graphics is a more capable GPU than Intel’s UHD Graphics 770 for light graphics work, though the database does not include GPU benchmark scores for either part. Buyers should pick the AMD part for embedded deployments, fanless designs, or battery-powered systems where low power draw and compact packaging are priorities. The Intel part is for desktop towers and workstations where performance per watt takes a back seat to absolute performance.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen Embedded 8640U uses the Zen 4 microarchitecture, codenamed Hawk Point, and belongs to the 8000 series. It is built on a 4 nm process at TSMC with 25,000 million transistors on a 178 mm² die. The Intel Core 9 273PQE uses the Bartlett Lake codename under the Core 9 generation and is fabricated on Intel’s 10 nm process. The Intel part has no listed transistor count or die size in the database.

Cache hierarchies differ significantly. The AMD chip has 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Intel chip has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. That larger shared L3 pool benefits the Intel processor in workloads that repeatedly access large data sets. The AMD part’s smaller per-core cache is offset by its lower core count, but the sheer size of Intel’s cache array gives it an edge in memory-bound tasks.

Memory support also diverges. The AMD processor supports DDR5 only, with a dual-channel memory bus and 89.6 GB/s of theoretical bandwidth. The Intel processor supports both DDR4 and DDR5, also dual-channel, with the same 89.6 GB/s peak bandwidth. Both parts support ECC memory, which matters for reliability-sensitive embedded and server applications. PCIe connectivity differs: the AMD chip provides Gen 4 with 20 lanes from the CPU, while the Intel chip provides Gen 5 with 16 lanes. The newer PCIe standard on the Intel side offers higher per-lane bandwidth for high-speed storage and expansion cards.

Integrated graphics are present on both. AMD uses the Radeon 760M, Intel uses UHD Graphics 770. The Radeon 760M is generally positioned as a more powerful iGPU in the database’s broader context, though no head-to-head GPU scores exist for this pair. The AMD part targets mobile and embedded form factors with an AMD Socket FP8, while the Intel part uses Intel Socket 1700 for desktop motherboards. Production status is active for both parts, with the AMD chip released in April 2024 and the Intel chip in March 2026.

The two parts also differ in part number availability, with the Intel chip carrying the part number SA4Q9, while the AMD chip’s part number is listed as unknown. Neither processor has an unlocked multiplier, so overclocking is not supported through standard multiplier adjustment.

Head-to-Head Benchmarks

The database contains benchmark scores for the Intel Core 9 273PQE across Cinebench and PassMark tests. The AMD Ryzen Embedded 8640U has no recorded benchmark scores in the database, so direct head-to-head test results are unavailable. However, the Intel part’s scores can be interpreted against its nearest rivals to show its performance tier.

In Cinebench R23 multicore, the Intel Core 9 273PQE scores 39190. That result places it in the high-end desktop territory, consistent with its 12-core configuration. Its single-core Cinebench R23 score of 5532 reflects the 5.90 GHz boost clock, which drives strong integer and floating-point single-thread performance. For comparison, the nearest rival Intel Core Ultra 5 250KF Plus has an average score of 66159, just 0.1% above the Core 9 273PQE’s 66099 average. The AMD Ryzen 9 7950X3D scores 65914 on average, 0.3% lower, indicating the Core 9 273PQE matches a top-tier AMD desktop processor.

Cinebench R20 results show a multicore score of 16459 and a single-core score of 2323 for the Intel chip. Cinebench R15 shows 3950 multicore and 557 single-core. These numbers confirm scaling across test versions, with the multicore scores growing proportionally to core count and the single-core scores tracking the high boost clock.

PassMark tests provide a broader view of workload performance. The Intel Core 9 273PQE scores 585752 in data compression, indicating strong throughput for archive and compression tasks. Data encryption scores 29636, extended instructions 38743, and find prime numbers 198. Floating point math reaches 125546, integer math 164629, and multithreaded performance 46107. Physics simulation scores 2754, random string sorting 53167, and single-thread performance 4573.

The Intel processor’s average benchmark score of 66099 places it just above the AMD Ryzen 9 7950X3D’s 65914, a 0.3% lead, and just below the Intel Core Ultra 5 250KF Plus’s 66159, a 0.1% gap. The Intel Core Ultra 5 250K Plus scores 66855, which is 1.1% higher, and the AMD EPYC 4465P scores 66925, 1.2% higher. These margins are small, meaning the Core 9 273PQE sits in a tightly contested performance band at the top of the desktop market.

The AMD Ryzen Embedded 8640U has no benchmark entries, so its performance must be inferred from its specifications. Its 6-core, 12-thread configuration with a 4.90 GHz boost clock and 16 MB L3 cache suggests moderate multithreaded capability, suitable for embedded control, edge computing, and light server tasks. The 28 watt TDP and 4 nm process indicate high efficiency, but the absence of recorded scores means the database cannot quantify its exact performance level. The Intel part clearly dominates in every measured workload category, but the AMD part’s value lies in power efficiency and compact integration, not raw speed.

The release timing also matters. The AMD chip launched in April 2024, while the Intel chip launched in March 2026, nearly two years later. That generational gap explains the Intel part’s higher core count, faster boost clock, and larger cache. The Intel processor’s launch MSRP is listed at $589, though the database provides no pricing information for the AMD part. No pricing comparison is possible beyond that single figure.

For embedded system designers, the AMD Ryzen Embedded 8640U offers a Zen 4 architecture on a 4 nm node with integrated Radeon 760M graphics, all within a 28 watt envelope. For desktop users, the Intel Core 9 273PQE delivers 24 threads, a 5.90 GHz boost, 36 MB of L3 cache, and PCIe Gen 5 support, ranking it in the top 7% of all CPUs in the database. The choice comes down to whether the workload requires maximum compute or maximum efficiency per watt.
