AMD A8-7670K vs Intel Core i3-1110G4 Comparison

The Intel Core i3-1110G4 and AMD A8-7670K present a fascinating study in architectural contrast. Despite the AMD chip offering double the physical cores, the benchmark data shows a consistent and decisive victory for the Intel part across every single test. The aggregate data places them nearly identically in the overall database — the i3-1110G4 holds an average benchmark score of 945, while the A8-7670K sits at 944, a negligible 0.1% difference. However, this near-parity in the aggregate is misleading, as the head-to-head Cinebench results reveal a different story, one of consistent single-thread and multi-thread dominance for the newer Intel processor.

Head-to-Head Benchmarks

The most striking outcome is the complete sweep. The Intel Core i3-1110G4 wins all five recorded head-to-head benchmark comparisons, with the AMD A8-7670K failing to secure a single victory. The margin of victory is remarkably consistent across all tests, hovering around 16.7%. For instance, in Cinebench R23 multi-core, the Intel chip scores 3202 against the AMD's 2745, a 16.6% advantage. This is particularly noteworthy because the AMD A8-7670K is a quad-core processor, while the Intel i3-1110G4 is only a dual-core part. The data implies that Intel's architecture is extracting far more work per core than AMD's older Steamroller design.

The single-core results are even more telling. In Cinebench R23 single-core, the i3-1110G4 achieves a score of 452, while the A8-7670K manages 387. The 16.8% lead in this test highlights a fundamental efficiency gap. This isn't just about having more cores; it's about the raw processing power of each individual core. The Intel chip’s 3.90 GHz boost clock matches the AMD's maximum boost, yet the Intel part still delivers a significantly higher score. This suggests that instructions per clock (IPC) is the decisive factor, not raw clock speed.

Looking at the Cinebench R20 results, the pattern holds. The i3-1110G4 scores 1344 in multi-core versus the A8-7670K’s 1152, and 189 versus 162 in single-core. The consistency of this ~16.7% delta across different benchmark versions and workloads suggests a systemic architectural advantage rather than a workload-specific quirk. Even in the older Cinebench R15 multi-core test, the Intel part leads with 322 points against the AMD's 276, a 16.7% margin. The data is unambiguous: for these rendering workloads, the Intel Core i3-1110G4 is the superior processor by a substantial and consistent margin.

Architecture Differences

The benchmark results are a direct consequence of the profound architectural differences between these two processors. The Intel Core i3-1110G4 is built on a modern 10 nm process node, codenamed Tiger Lake-U, and features the Willow Cove microarchitecture. In contrast, the AMD A8-7670K uses a much older 28 nm process node and the Steamroller architecture, codenamed Godaveri. This generational gap in manufacturing technology alone explains much of the performance and efficiency disparity, as the smaller node allows for more transistors in a smaller space and lower power consumption.

The core counts differ significantly. The Intel chip has 2 physical cores but supports 4 threads via Hyper-Threading. The AMD chip has 4 physical cores and 4 threads, with no equivalent technology. Despite having half the physical cores, the Intel processor still wins in multi-threaded workloads, as the benchmark scores demonstrate. This is a powerful statement about the efficiency of the Willow Cove cores versus the Steamroller cores. The cache hierarchy also tells a story. The Intel i3-1110G4 has a 6 MB shared L3 cache, while the AMD A8-7670K has no L3 cache at all, relying instead on a larger 4 MB L2 cache. The Intel's per-core L1 cache is listed as 96 KB, while the AMD's total L1 is 256 KB, but the way these caches are utilized differs dramatically.

Memory support is another major differentiator. The Intel processor supports DDR4 memory with a dual-channel bus, yielding a theoretical memory bandwidth of 59.7 GB/s. The AMD part is limited to DDR3, also dual-channel, with a significantly lower bandwidth of 34.1 GB/s. This higher bandwidth is crucial for integrated graphics and memory-intensive tasks. The integrated GPUs also reflect their respective eras: the Intel chip features Iris Xe Graphics G4, while the AMD has Radeon R7. The platform is fundamentally different, with the Intel being a mobile part on the BGA 1598 socket and the AMD being a desktop part on the FM2+ socket. The Intel chip is also an active production part, while the AMD A8-7670K is end-of-life.

The Verdict

The data in this comparison is unequivocal. For compute-intensive tasks like video rendering, the Intel Core i3-1110G4 is the superior processor, winning every benchmark by a consistent margin of approximately 16.7%. The near-identical aggregate scores (945 vs 944) are a statistical artifact that obscures the fact that the Intel chip wins in every specific workload tested. The AMD A8-7670K's advantage in physical core count is completely neutralized by the older, less efficient Steamroller architecture.

The choice between these two is clear from the benchmark results. The Intel Core i3-1110G4 is the better performer for Cinebench workloads, offering higher scores in both single-core and multi-core tests. The fact that it achieves this with a 15 W TDP compared to the AMD's 95 W TDP further underscores its efficiency. The AMD A8-7670K, being an end-of-life product on an older platform, cannot compete with the modern Tiger Lake-U architecture of the Intel chip. For anyone looking at raw processing power as measured by these benchmarks, the Intel Core i3-1110G4 is the definitive choice. The AMD part's only remaining appeal would be its unlocked multiplier, but the benchmark data shows no performance benefit from this feature in the tests conducted.

Specification Differences

The two processors differ in nearly every fundamental specification. The Intel Core i3-1110G4 is a 2-core, 4-thread mobile processor with a base clock of 1800.00 MHz and a boost clock of 3.90 GHz. The AMD A8-7670K is a 4-core, 4-thread desktop processor with a base clock of 3.60 GHz and an identical 3.90 GHz boost clock. The Intel part has a TDP of 15 W, while the AMD part has a TDP of 95 W.

The manufacturing process is a major difference: the Intel chip uses a 10 nm node from Intel, while the AMD chip uses a 28 nm node from GlobalFoundries. The AMD chip has a listed transistor count of 2,411 million and a die size of 245 mm²; the Intel chip has no listed figures for these. The cache configurations are also different: the Intel chip has 96 KB of L1 cache per core and 1.25 MB of L2 cache per core, plus a 6 MB shared L3 cache. The AMD chip has 256 KB of L1 cache and 4 MB of L2 cache, with no L3 cache.

Memory support differs significantly, with the Intel part supporting DDR4 and the AMD part supporting DDR3. The Intel's memory bandwidth is 59.7 GB/s, while the AMD's is 34.1 GB/s. They also use different sockets: Intel BGA 1598 for the i3-1110G4 and AMD Socket FM2+ for the A8-7670K. The integrated graphics are different (Iris Xe Graphics G4 vs Radeon R7), as are the PCIe versions (Gen 4 vs Gen 3). Finally, the Intel chip is an active production part released in 2020, while the AMD chip is end-of-life and was released in 2015. The AMD A8-7670K has an unlocked multiplier, which the Intel chip does not.

Where Each One Wins

Based strictly on the benchmark data, the Intel Core i3-1110G4 wins in every category that was tested. It achieves victory in all five head-to-head Cinebench tests, covering both single-core and multi-core workloads across R15, R20, and R23 versions. This means the Intel chip is the better choice for any application that relies on CPU rendering performance, whether that workload is lightly threaded or heavily threaded. The consistent 16.7% lead suggests that the Intel architecture is more efficient at executing instructions, making it the superior part for general-purpose compute tasks.

The AMD A8-7670K has zero benchmark wins in this comparison. However, the data suggests it is not without its own characteristics. It has a higher base clock (3.60 GHz vs 1800.00 MHz), which could theoretically benefit workloads that run at a constant frequency rather than boosting. It also has an unlocked multiplier, which is a feature for enthusiasts, although the performance impact cannot be quantified from the data provided. The AMD chip's integrated Radeon R7 graphics and its desktop platform are differentiators, but the benchmark results do not cover graphics performance. In terms of CPU compute as measured by Cinebench, the AMD A8-7670K has no wins. The Intel Core i3-1110G4 is the clear victor in all measured aspects of CPU performance.
