AMD PRO A10-8850B vs Intel Core i3-6320 Comparison

Where Each One Wins

The benchmark data splits cleanly between these two desktop processors, with the Intel Core i3-6320 taking every recorded head-to-head victory. The database records five benchmark comparisons across Cinebench R15, R20, and R23, covering both multi-core and single-core workloads. The Intel part wins all five, while the AMD PRO A10-8850B does not claim a single win in any recorded test.

For multi-threaded workloads, the Intel Core i3-6320 shows a consistent advantage. In Cinebench R15 multi-core, the Intel part scores 378 against the AMD's 321, a delta of 17.8 percent. The R20 multi-core test shows a similar pattern: 1576 for Intel versus 1339 for AMD, a 17.7 percent gap. The R23 multi-core result repeats this trend with 3753 versus 3189, again a 17.7 percent difference. These results indicate that despite having only two physical cores and four threads, the Intel processor outperforms the AMD's four cores and four threads in every multi-core scenario recorded.

Single-core performance tells the same story. In Cinebench R20 single-core, the Intel Core i3-6320 scores 222, while the AMD PRO A10-8850B manages 189, a 17.5 percent delta. The R23 single-core test shows 529 versus 450, a 17.6 percent gap. These single-threaded wins are particularly telling because the AMD part has a higher boost clock, but the Intel architecture still delivers better per-thread results.

The overall average benchmark scores in the database place these two chips very close: the Intel Core i3-6320 averages 1085, while the AMD PRO A10-8850B averages 1098. The AMD part sits at the 31st percentile among all CPUs, marginally ahead of the Intel's 30th percentile. However, that aggregate closeness masks the fact that every direct comparison in the recorded data favors Intel. The AMD's average is buoyed by its nearest rivals, which include the Intel Xeon E5-1603 v3 at 1098 and the Intel Pentium 6805 at 1099, but those are different chips, not direct comparisons with the i3-6320.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i3-6320 uses the Skylake architecture on a 14 nm process node, manufactured by Intel. It integrates 1,400 million transistors on a 150 mm² die. The AMD PRO A10-8850B uses the Steamroller architecture, codenamed Godaveri, on a 28 nm process node from GlobalFoundries. It packs 2,411 million transistors across a larger 245 mm² die.

The core counts differ, but the thread counts align. Intel provides 2 cores with 4 threads via Hyper-Threading, while AMD offers 4 physical cores with 4 threads and no simultaneous multi-threading. Both run at a 3.90 GHz base clock, but the AMD part has a 4.10 GHz boost clock, while the Intel part has no boost clock recorded.

Cache layouts diverge substantially. The Intel i3-6320 carries 64 KB of L1 cache per core, 256 KB of L2 per core, and a shared 4 MB L3 cache. The AMD PRO A10-8850B has a unified 256 KB L1 and a 4 MB L2, with no L3 cache at all. The AMD's larger transistor count and die size reflect its older 28 nm process and more complex memory hierarchy, but the recorded benchmarks show that Intel's smaller, denser design delivers better performance in every measured test.

Memory support differs by generation. The Intel part supports DDR4 memory, while the AMD part uses DDR3. Both use a dual-channel memory bus, and the database records identical memory bandwidth of 34.1 GB/s for both. Neither supports ECC memory. Both use PCIe Gen 3 with 16 lanes from the CPU.

The integrated graphics also differ: Intel bundles HD 530, while AMD includes Radeon R7. The Intel processor is listed as active in production, while the AMD is marked end-of-life. The AMD was released about a month later, on 2015-09-28, versus the Intel's 2015-08-31.

Head-to-Head Benchmarks

The largest margin in the recorded data appears in the Cinebench R15 multi-core test, where the Intel Core i3-6320 leads by 17.8 percent. That test shows 378 for Intel against 321 for AMD. The R20 multi-core test shows a 17.7 percent gap with scores of 1576 and 1339. The R23 multi-core test matches that 17.7 percent delta with 3753 versus 3189.

Single-core deltas are nearly identical. The R20 single-core test shows a 17.5 percent lead for Intel, with 222 against 189. The R23 single-core test shows 17.6 percent, with 529 versus 450. Across all five comparisons, the margins cluster tightly between 17.5 and 17.8 percent. This consistency suggests a stable architectural advantage rather than a workload-specific quirk.

The Intel part wins every single comparison, so the scoreboard reads 5 wins for Intel and 0 for AMD. There is no recorded test where the AMD PRO A10-8850B comes out ahead. Even the R15 single-core test, which exists in the Intel benchmark list with a score of 53, has no corresponding AMD entry in the head-to-head data, so it does not factor into the comparison.

The Verdict

The data points to a clear choice for most workloads: the Intel Core i3-6320. It wins every recorded benchmark, with margins between 17.5 and 17.8 percent across both single-core and multi-core tests. Despite featuring only 2 cores versus the AMD's 4, the Intel part delivers higher scores in all Cinebench versions, reflecting a more efficient architecture on a smaller 14 nm process node versus the AMD's 28 nm Steamroller design.

The AMD PRO A10-8850B does have a higher average benchmark score in the database (1098 versus 1085) and sits at a slightly better percentile (31st versus 30th), but that aggregate figure includes comparisons with other processors, not direct measurements against the i3-6320. In every recorded head-to-head test, the Intel part leads.

Buyers who prioritize multi-threaded rendering in Cinebench should select the Intel Core i3-6320. Its 3753 R23 multi-core score beats the AMD's 3189 by a substantial 17.7 percent, even though the AMD has twice the physical core count. Users who need lower power consumption should also favor Intel, given the 51 W TDP versus 95 W for AMD.

The AMD part remains competitive only in the narrow sense of its aggregate average, but the recorded data shows no scenario where it outpaces the Intel chip. Since the AMD is end-of-life and the Intel is active, the practical choice for new builds is the Intel Core i3-6320, assuming the socket and memory platform (DDR4) are acceptable. The AMD's DDR3 support and Socket FM2+ represent an older platform with no recorded performance advantage to justify the higher power draw and larger die.
