AMD A8-6600K vs Intel Core i3-7100 Comparison

Where Each One Wins

The benchmark data splits cleanly along generational and architectural lines. The Intel Core i3-7100 dominates every recorded benchmark in the head-to-head comparison, while the AMD A8-6600K does not register a single win in the shared test suite. That said, the two processors occupy different performance tiers, and the nature of their wins matters more than the raw count.

In the Geekbench multicore test, the Intel Core i3-7100 scores 1501 against the AMD A8-6600K's 1076. That is a 39.5% advantage for Intel. This is notable because the AMD part has four physical cores, while the Intel part has only two cores but four threads. The Intel chip's higher instructions per clock and newer microarchitecture overcome the core count deficit. The multicore result shows that thread count alone does not guarantee performance when comparing a modern dual-core with hyper-threading against an older quad-core design.

The single-core picture is even more lopsided. The Intel Core i3-7100 scores 722 in Geekbench single-core, while the AMD A8-6600K scores 451. The 60.1% delta is the largest gap in the entire comparison. This is the clearest indicator of the architectural gulf between the two. Single-core performance drives responsiveness in many everyday workloads, from web browsing to office applications, and the Intel part holds a commanding lead here.

Looking at the broader benchmark suite, the Intel Core i3-7100 has an average benchmark score of 781 across all its recorded tests. The AMD A8-6600K averages 764. The Intel chip sits at the 21st percentile of all CPUs in the database, while the AMD chip sits at the 20th percentile. These are adjacent performance percentiles, but the Intel part achieves its position with a much smaller physical footprint (two cores versus four) and a significantly lower thermal envelope.

The nearest rivals for each chip reinforce the positioning. The Intel Core i3-7100's closest competitor is the AMD A10-5800K, which scores 778, a 0.4% difference. The AMD A8-6600K's nearest rival is the Intel Core i7-3537U, which scores 766, a -0.3% difference. This suggests that while the two CPUs have similar average scores, they achieve them through different means and are surrounded by different sets of competitors.

The Verdict

The benchmark data points to a clear recommendation for most users. The Intel Core i3-7100 wins every head-to-head benchmark in the database, and the margins are substantial. In Geekbench multicore, it is 39.5% ahead. In Geekbench single-core, it is 60.1% ahead. These are not marginal differences; they represent a full generation or more of architectural advancement.

For users who prioritize single-threaded performance, which includes everyday desktop tasks, web browsing, and many legacy applications, the Intel Core i3-7100 is the obvious choice. The 60.1% single-core advantage is decisive. Even in workloads that scale across multiple threads, the Intel chip maintains a 39.5% lead. The data shows no scenario where the AMD A8-6600K comes out ahead.

The AMD A8-6600K does have its merits, but they do not appear in the benchmark scores. It has an unlocked multiplier, which means the user can overclock it. It also has a higher transistor count (1,303 million) and a larger die size (246 mm²). However, these are architectural characteristics, not performance metrics. The recorded benchmarks do not show any test where the AMD chip wins.

The classification is also worth noting. The Intel Core i3-7100 is listed as "Active" production status, while the AMD A8-6600K is "End-of-life." For a new build, the data points to the Intel part. The AMD chip's 100W TDP is also nearly double the Intel chip's 51W TDP, which is a significant difference in thermal and power requirements.

In short, the verdict is unambiguous: the Intel Core i3-7100 is the faster processor in every measured dimension. The only reason to consider the AMD A8-6600K would be for its overclocking headroom or its integrated Radeon HD 8570D graphics, but neither of those factors is captured in the benchmark scores.

Head-to-Head Benchmarks

The head-to-head comparison includes two Geekbench tests, and the Intel Core i3-7100 wins both. The results are as follows:

Geekbench Multicore: Intel Core i3-7100 scores 1,501. AMD A8-6600K scores 1,076. The Intel chip wins by 39.5%. This is a substantial margin for a benchmark that scales with core count. The AMD chip has four physical cores versus Intel's two cores with hyper-threading. The fact that Intel still wins by nearly 40% indicates that the AMD "Piledriver" architecture suffers from a significant per-core efficiency deficit. The Intel part's 14nm process node and newer Kaby Lake architecture more than compensate for the core count gap.

Geekbench Single-Core: Intel Core i3-7100 scores 722. AMD A8-6600K scores 451. The Intel chip wins by 60.1%. This is the largest delta in the head-to-head data. Single-core performance is critical for applications that cannot effectively use multiple threads. The AMD chip's 32nm process and older Richland architecture (a Piledriver variant) simply cannot compete with Intel's Kaby Lake design at the same 3.90 GHz base clock. The Intel chip also lacks a boost clock, while the AMD chip can boost to 4.20 GHz, but the Intel chip still wins by a wide margin.

The overall head-to-head record is 2 wins for Intel, 0 for AMD. The average benchmark score for the Intel chip is 781, while the AMD chip averages 764. The Intel chip sits slightly higher in the global percentile ranking (21st versus 20th). However, the average scores do not tell the whole story. The Intel chip's edge is much more pronounced in tests of raw performance, while the averages are pulled closer by the AMD chip's relative strength in some undefined workloads.

The nearest rivals in the database add context. The Intel Core i3-7100's closest rivals are the AMD A10-5800K (778, 0.4% delta) and the Intel Pentium G4520 (778, 0.4% delta). The AMD A8-6600K's nearest rivals include the Intel Core i7-3537U (766, -0.3%) and the Intel Core i3-3240 (761, 0.5%). This suggests that the Intel chip competes with a slightly higher tier of processors, while the AMD chip sits alongside older and lower-power parts.

Architecture Differences

The two processors come from completely different design eras and philosophies. The Intel Core i3-7100 uses the Kaby Lake architecture on a 14nm process node, fabricated by Intel. The AMD A8-6600K uses the Piledriver architecture (codename Richland) on a 32nm process, fabricated by GlobalFoundries. The node difference is significant: 14nm versus 32nm explains much of the performance and efficiency gap.

The cache layout also differs. The Intel chip has a per-core L1 cache of 64 KB and a per-core L2 cache of 256 KB, plus a shared 3 MB L3 cache. The AMD chip has a total L1 cache of 192 KB and a total L2 cache of 4 MB, with no L3 cache. The Intel chip's L3 cache is a notable feature, as it allows data sharing between the two cores and threads.

Memory support is another major divergence. The Intel chip supports DDR4 memory with a dual-channel bus and a bandwidth of 38.4 GB/s. The AMD chip supports DDR3 memory with a dual-channel bus and a bandwidth of 29.9 GB/s. This gives the Intel chip a 28.4% memory bandwidth advantage, which affects performance in memory-sensitive workloads.

The integrated graphics also differ. The Intel chip includes Intel HD 630 graphics, while the AMD chip includes Radeon HD 8570D graphics. The database does not provide benchmark scores for either integrated GPU, so a performance comparison is not possible from the data.

The AMD chip has an unlocked multiplier, which the Intel chip does not. This makes the AMD part more flexible for overclocking, though the Intel part's higher stock performance reduces the need for it. The AMD chip also has a boost clock of 4.20 GHz, while the Intel chip has no boost clock recorded, running at a fixed 3.90 GHz.

The die size and transistor count are also notable. The AMD chip has 1,303 million transistors on a 246 mm² die, while the Intel chip has no transistor count or die size recorded. The AMD's larger The die and process node are a disadvantage in power efficiency, which is reflected in the 100W TDP.

Specification Differences

The two processors differ in nearly every specification category. Here is a breakdown of the fields where they do not match:

• Threads: Intel has 4 threads, AMD has 4 threads. This is a match, but the core count differs (Intel 2, AMD 4).
• Boost Clock: Intel has none, AMD has 4.20 GHz.
• TDP: Intel 51W, AMD 100W.
• Socket: Intel Socket 1151, AMD Socket FM2.
