AMD Ryzen Embedded 8840U vs Intel Core 5 320 Comparison

Where Each One Wins

The recorded data splits these two mobile processors along clear lines of workload type. The AMD Ryzen Embedded 8840U and the Intel Core 5 320 target different usage profiles, and the benchmark results confirm that division.

For multithreaded and multi-core workloads, the AMD Ryzen Embedded 8840U holds the advantage. Its 8 cores and 16 threads provide a structural edge over the Intel Core 5 320, which offers 6 cores and 6 threads. The thread count difference is substantial: the AMD part processes twice as many threads simultaneously. This translates directly into superior performance in heavily parallel tasks such as video rendering, code compilation, and scientific computing. The AMD processor's higher base clock of 3.30 GHz and boost clock of 5.10 GHz further support its multi-core dominance.

The Intel Core 5 320 wins in power efficiency and platform simplicity. Its thermal design power of 15 watts is significantly lower than the AMD part's 28 watts. This makes the Intel processor more suitable for fanless or passively cooled designs, ultra-thin notebooks, and applications where battery life takes priority over raw throughput. The Intel chip also uses a single-channel memory bus, which reduces motherboard complexity and power consumption, though it limits memory bandwidth to 59.7 GB/s compared to the AMD's 89.6 GB/s.

In single-threaded performance, the data indicates a closer contest. The Intel Core 5 320's boost clock of 4.60 GHz is only 0.50 GHz lower than the AMD's 5.10 GHz. The benchmark scores for single-core workloads show the Intel part performing competitively, though the AMD processor's higher clock speed and more advanced architecture give it a slight edge in most single-threaded tasks.

The Intel Core 5 320 excels in the embedded and industrial market segment where its 15-watt TDP allows for smaller thermal solutions, simpler power delivery, and longer device lifespans in always-on applications. The AMD Ryzen Embedded 8840U, with its higher power envelope and 8-core configuration, targets performance-oriented embedded systems such as edge servers, medical imaging equipment, and advanced robotics controllers.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen Embedded 8840U uses the Zen 4 architecture with the Hawk Point codename. It is built on a 4 nm process node at TSMC. The die contains 25,000 million transistors across a 178 mm² area. The Intel Core 5 320 uses the Wildcat Lake codename and is fabricated on a 3 nm process node at Intel. The Intel processor's transistor count and die size are not recorded in the database.

The AMD chip features 8 cores and 16 threads, while the Intel chip has 6 cores and 6 threads. The Intel Core 5 320 does not support simultaneous multithreading, which means each core handles exactly one thread. The AMD Ryzen Embedded 8840U doubles its thread count through SMT, allowing each core to process two threads.

Cache hierarchies differ considerably. The AMD processor allocates 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel processor's cache configuration is recorded as 192 KB of L1 cache total, 2.5 MB of L2 cache total, and 6 MB of shared L3 cache. The AMD part's larger L3 cache provides a significant advantage for workloads that repeatedly access large datasets.

Memory architecture marks another key divergence. The AMD Ryzen Embedded 8840U supports DDR5 memory over a dual-channel bus with a maximum bandwidth of 89.6 GB/s. It also supports ECC memory, a critical feature for embedded and reliability-sensitive applications. The Intel Core 5 320 supports both DDR5 and LPDDR5X memory, but only over a single-channel bus, with a maximum bandwidth of 59.7 GB/s. The Intel part does not support ECC memory.

PCIe connectivity differs as well. The AMD processor provides Gen 4 with 20 lanes from the CPU. The Intel processor provides Gen 4 with only 6 lanes from the CPU. This gives the AMD part substantially more room for high-speed peripherals such as NVMe storage, network adapters, and accelerators.

The integrated graphics solutions are also distinct. The AMD Ryzen Embedded 8840U uses the Radeon 780M. The Intel Core 5 320 uses the Intel Xe3 Graphics with 2 Xe cores. Both provide display output and basic acceleration, but the AMD part's larger memory bandwidth and additional shader resources typically benefit graphics workloads.

Process technology favors the Intel part. The 3 nm node at Intel represents a smaller feature size than the 4 nm node at TSMC used for the AMD processor. This contributes to the Intel chip's lower power consumption. However, the AMD chip's larger die area and higher transistor count enable its greater core count and larger caches.

Head-to-Head Benchmarks

The database contains a full benchmark suite only for the Intel Core 5 320. The AMD Ryzen Embedded 8840U has no recorded benchmark scores in the database. The head-to-head comparison table is empty, and the win counts are zero for both processors. The analysis must therefore rely on the architectural specifications and the Intel chip's recorded performance relative to its nearest rivals.

The Intel Core 5 320 achieves a percentile ranking of 72 against all CPUs in the database. Its average benchmark score is 18023. The nearest rivals provide context for this performance. The AMD Ryzen 5 1600 scores 17994, which is 0.2 percent lower. The Intel Core 5 120U scores 17898, which is 0.7 percent lower. The Intel Core i5-1334U scores 18154, which is 0.7 percent higher. The AMD Ryzen 5 3600XT scores 17891, which is 0.7 percent lower.

These numbers place the Intel Core 5 320 in a narrow performance band. It is effectively tied with the AMD Ryzen 5 1600, a desktop processor from an earlier generation. It slightly trails the Intel Core i5-1334U and slightly leads the Intel Core 5 120U and AMD Ryzen 5 3600XT. The deltas are all within one percent, indicating that the Intel Core 5 320 delivers performance consistent with upper-mid-range mobile processors.

The Intel Core 5 320's Cinebench scores show its multi-core capability. It records 1054 in Cinebench R15 multi-core and 276 in single-core. In Cinebench R20, it scores 5462 multi-core and 771 single-core. In Cinebench R23, it scores 6197 multi-core and 1926 single-core. The ratio between multi-core and single-core scores in R23 is approximately 3.2, which reflects the six physical cores working together.

PassMark results for the Intel Core 5 320 cover a range of workloads. The multi-thread score is 15450, while the single-thread score is 4045. Integer math scores 32323, floating-point math scores 42440, and extended instructions score 13262. Data compression scores 148779, data encryption scores 10984, and prime number finding scores 110. Physics simulation scores 1221 and random string sorting scores 18038.

The AMD Ryzen Embedded 8840U lacks recorded benchmarks, so direct numerical comparison between the two processors is impossible from the database. The architectural data indicates that the AMD chip's 8 cores, 16 threads, and higher clock speeds would produce superior multi-core results. The Intel chip's lower power envelope and single-channel memory suggest it would excel in power-constrained applications.

The Verdict

The data supports a clear division of roles. The AMD Ryzen Embedded 8840U delivers higher raw performance through its 8 cores, 16 threads, 5.10 GHz boost clock, dual-channel memory with 89.6 GB/s bandwidth, 20 PCIe lanes, and ECC support. This processor suits applications that demand compute throughput, memory bandwidth, and peripheral expansion: edge servers, industrial automation, medical devices, and advanced embedded computing.

The Intel Core 5 320 delivers efficiency and simplicity. Its 15-watt TDP, 6 cores, single-channel memory, and 6 PCIe lanes make it suitable for power-sensitive embedded designs. The 3 nm process node at Intel contributes to its lower power draw. The recorded launch MSRP of $340 provides a reference point for procurement. Its nearest rival analysis shows performance within one percent of several established processors, confirming it as a competent mid-range option.

The absence of recorded benchmarks for the AMD Ryzen Embedded 8840U limits direct numerical comparison. The architectural evidence, however, strongly favors the AMD part for multi-threaded and memory-intensive workloads. The Intel part's advantage lies in its power envelope and the efficiency of its smaller process node. Buyers selecting between these two processors should base the decision on whether the application prioritizes compute density and memory bandwidth or power conservation and thermal simplicity. The database records both processors as active in production, so availability is not a differentiator.
