AMD A10-7850K vs Intel Core i3-7100 Comparison

The Verdict

The data in this comparison is one-sided. The Intel Core i3-7100 wins every recorded head-to-head benchmark against the AMD A10-7850K. For a builder choosing between these two desktop processors today, the decision hinges on what you prioritize: the Intel chip delivers clearly superior CPU performance in both single-core and multi-core workloads, while the AMD part offers an unlocked multiplier and an older, end-of-life platform.

Benchmark results show the Core i3-7100 takes the Geekbench multi-core test with a score of 1501 against 1139 for the A10-7850K, a 24.1% gap. In single-core, the Intel part scores 722 versus 453, a 37.3% lead. The A10-7850K has zero benchmark wins in the recorded head-to-head data. If you need raw processing power, the Core i3-7100 is the clear pick. If you value an unlocked multiplier for overclocking and do not mind an older socket, the A10-7850K remains a functional option, but the performance penalty is substantial.

Architecture Differences

The two processors come from different design eras and foundries. The AMD A10-7850K uses the Steamroller architecture, codenamed Kaveri, built on a 28 nm process at GlobalFoundries. It integrates a Radeon R7 graphics unit and fits into the AMD Socket FM2+. The Intel Core i3-7100 uses the Kaby Lake architecture, also codenamed Kaby Lake, built on a 14 nm process at Intel. It integrates Intel HD 630 graphics and fits into Intel Socket 1151.

The core configurations differ significantly. The A10-7850K has 4 physical cores and 4 threads, while the Core i3-7100 has 2 physical cores and 4 threads, using Hyper-Threading to reach the same thread count. The AMD part has a base clock of 3.70 GHz and a boost clock of 4.00 GHz. The Intel part has a higher base clock of 3.90 GHz and no boost clock, relying on its higher base frequency and architectural efficiency.

Cache layouts also diverge. The A10-7850K has 256 KB of L1 cache and 4 MB of L2 cache, with no L3 cache. The Core i3-7100 has 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 3 MB of shared L3 cache. The Intel chip also supports DDR4 memory with dual-channel configuration and a memory bandwidth of 38.4 GB/s, while the AMD part supports DDR3. Both have PCIe Gen 3 with 16 lanes from the CPU. The A10-7850K has an unlocked multiplier for overclocking; the Core i3-7100 does not.

Head-to-Head Benchmarks

The recorded head-to-head data contains two Geekbench tests, and the Intel Core i3-7100 wins both. In Geekbench multi-core, the Core i3-7100 scores 1501, which is 24.1% higher than the A10-7850K's 1139. This is notable because the AMD part has twice the physical core count. The Intel chip's higher base clock and more efficient architecture overcome the core deficit.

In Geekbench single-core, the gap widens. The Core i3-7100 scores 722, a 37.3% advantage over the A10-7850K's 453. This is a decisive margin for any workload that relies on single-threaded performance, such as older games or lightly threaded applications. The A10-7850K simply cannot keep pace in this metric.

The overall average benchmark score tells a similar story. The A10-7850K averages 796 points, while the Core i3-7100 averages 781 points. Despite the Intel chip winning both head-to-head tests, the averages are close because the AMD part has a higher score in one of its nearest rival comparisons. Both processors sit at the 21st percentile among all CPUs in the database, meaning they occupy a similar overall performance tier, but the specific test results show the Intel part is stronger in the measured areas.

FAQ

Where Each One Wins

The AMD A10-7850K does not win any recorded head-to-head benchmark. Its strengths lie outside the measured tests. It has an unlocked multiplier, allowing overclocking flexibility for users who want to push the chip beyond stock settings. It also has 4 physical cores, which can be beneficial in workloads that scale with raw core count, even though the benchmark data shows the Intel chip wins multi-core tests anyway. The A10-7850K also integrates a Radeon R7 GPU, which may offer different graphics capabilities compared to the Intel HD 630, though the benchmark data does not cover graphics performance.

The Intel Core i3-7100 wins every recorded benchmark comparison. It is the better choice for single-threaded applications, where its 37.3% lead in Geekbench single-core matters most. It also wins multi-threaded workloads by 24.1%, making it the stronger all-around CPU for general computing, productivity, and gaming tasks that rely on CPU performance. Its lower TDP of 51 watts versus 95 watts for the AMD part also suggests it runs cooler and more efficiently, though the exact cooling requirements are not specified in the data. The Core i3-7100 is also the only one of the two that remains in active production, which can matter for availability and long-term support.
