AMD A10-6800K vs Intel Pentium Silver J5040 Comparison

Head-to-Head Benchmarks

The recorded database does not contain any direct head-to-head benchmark results between the AMD A10-6800K and the Intel Pentium Silver J5040. Instead, the comparison must be built from their respective individual benchmark scores and average performance metrics.

The AMD A10-6800K delivers a Geekbench multi-core score of 1140 and a single-core score of 478. The Intel Pentium Silver J5040 has no Geekbench entries, but it provides Cinebench R15, R20, and R23 results. In Cinebench R15, the J5040 scores 276 multi-core and 91 single-core. In Cinebench R20, it scores 1150 multi-core and 162 single-core. In Cinebench R23, it scores 2739 multi-core and 386 single-core.

The average benchmark score for the A10-6800K is 809, placing it at the 22nd percentile of all CPUs. The J5040 averages 801, sitting at the 21st percentile. The A10-6800K is effectively tied with the Intel Core i7-870S (delta 0%), while it is 0.4% ahead of both the AMD Athlon X4 850 and the Intel Xeon X5482, and 0.5% behind the Intel Core i7-5550U. The J5040 matches the AMD A10-7700K and Intel Xeon E5530 exactly (delta 0%), trails the Intel Core i5-3320M by 0.2%, and lags the AMD Ryzen 3 2200U by 0.5%.

The data indicates that the two processors are extremely close in aggregate performance. The A10-6800K holds a marginal 1% advantage in average benchmark score (809 versus 801). However, the J5040’s newer Cinebench scores show a different picture in specific workloads. Its Cinebench R23 multi-core result of 2739 suggests strong sustained throughput for a 10 W part, while the A10-6800K’s single Geekbench multi-core score of 1140 is harder to map directly to Cinebench numbers. Without shared test suites, the only safe conclusion is a statistical near-tie: the A10-6800K edges ahead by 8 points in the aggregate metric, but the J5040’s percentile difference is just one point lower.

Architecture Differences

The two processors come from fundamentally different design eras and philosophies. The AMD A10-6800K uses the Piledriver architecture on the Richland codename, built on a 32 nm process at GlobalFoundries. It integrates 1,303 million transistors on a 246 mm² die. The Intel Pentium Silver J5040 uses the Goldmont Plus architecture on the Gemini Lake codename, fabricated on Intel’s 14 nm process with a 93 mm² die. Transistor count is not recorded for the J5040.

Both parts have four cores and four threads, but their cache layouts differ. The A10-6800K has 192 KB of L1 cache and 4 MB of L2 cache, with no L3 cache. The J5040 has 56 KB of L1 cache per core (224 KB total for four cores) and 4 MB of shared L2 cache, also with no L3 cache. The L2 total is the same at 4 MB, but the J5040’s shared design differs from the A10’s per-module arrangement.

Memory support separates them clearly. The A10-6800K uses dual-channel DDR3 with a measured memory bandwidth of 34.1 GB/s. The J5040 uses dual-channel DDR4 with a higher memory bandwidth of 38.4 GB/s. Neither supports ECC memory. PCIe connectivity is Gen 2 for both, but the J5040 is limited to 6 CPU lanes, while the A10-6800K’s lane count is not specified in the database.

The integrated graphics also differ. The A10-6800K carries a Radeon HD 8670D, while the J5040 includes Intel UHD Graphics 605. The A10-6800K has an unlocked multiplier, whereas the J5040 is locked. The A10-6800K has a 100 W TDP, while the J5040 consumes just 10 W, a tenfold difference. The A10-6800K uses the AMD Socket FM2, while the J5040 is soldered to Intel BGA 1090. The A10-6800K is classified as a desktop part, while the J5040 is classified as mobile. Both are end-of-life products. The A10-6800K was released in 2013, while the J5040 came in 2019.

The Verdict

The data supports a clear split decision based on workload type and platform constraints. For raw multi-threaded performance in older, single-test scenarios like Geekbench, the AMD A10-6800K holds a slight edge with a multi-core score of 1140 and an average of 809 versus the J5040’s 801. The A10-6800K also offers an unlocked multiplier, which allows overclocking on supported FM2 motherboards, a feature the J5040 lacks.

However, the Intel Pentium Silver J5040 wins decisively on efficiency and modern workload scaling. Its Cinebench R23 multi-core score of 2739 at a 10 W TDP is remarkable compared to the A10-6800K’s 100 W envelope. The J5040 also supports DDR4 memory with higher bandwidth (38.4 GB/s versus 34.1 GB/s), which contributes to better memory-bound performance. For systems where power consumption, heat output, or battery life matter, the J5040 is the only logical choice from the recorded data.

The A10-6800K should be chosen by users who need an upgradeable desktop CPU with an unlocked multiplier and are willing to tolerate high power draw. The J5040 should be chosen for compact, low-power, always-on systems where the 10 W TDP and modern Cinebench results indicate better efficiency per watt. The average benchmark scores are nearly identical, so the deciding factors are platform compatibility, power budget, and the specific benchmark suite used.
