Intel Core i5-4670K vs Intel Core i7-4810MQ Comparison

The Verdict

The benchmark data splits this pairing cleanly along workload type. The Intel Core i7-4810MQ wins six of eight head-to-head tests, sweeping every Cinebench R15, R20, and R23 run by margins between 6.9% and 7.6%. The Intel Core i5-4670K counters with two decisive Geekbench wins, taking the multi-core test by 15.5% and the single-core test by 17.7%. For sustained multi-threaded rendering, the i7-4810MQ is the clear choice. For Geekbench-style workloads, the i5-4670K is meaningfully faster. The average benchmark scores are nearly identical — 1656 for the i5-4670K versus 1651 for the i7-4810MQ — and both sit at the 40th percentile of all CPUs. The i5-4670K is the pick for desktop builders who want an unlocked multiplier and a socket that allows overclocking. The i7-4810MQ is the pick for mobile users who need eight threads in a 47 W envelope. Neither dominates outright; the data shows a workload-dependent split.

Architecture Differences

Both processors share the same Haswell architecture, 22 nm process node, and Intel foundry. Each uses 1,400 million transistors on a 177 mm² die. The cache layouts are identical: 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3. Both support DDR3 memory over a dual-channel bus, and both integrate Intel HD 4600 graphics with PCIe Gen 3 connectivity. The core difference is threading. The i5-4670K offers 4 cores and 4 threads, while the i7-4810MQ offers 4 cores and 8 threads via Hyper-Threading. Clock speeds differ at the base level — 3.40 GHz for the i5-4670K versus 2.80 GHz for the i7-4810MQ — but both boost to 3.80 GHz. The i5-4670K is a desktop part on Intel Socket 1150 with an unlocked multiplier; the i7-4810MQ is a mobile part on Intel Socket G3 with a locked multiplier. The i7-4810MQ lists a launch MSRP of $378. The i5-4670K has no launch MSRP listed. The i7-4810MQ is marked end-of-life, while the i5-4670K has no production status listed. Memory bandwidth is specified only for the i7-4810MQ at 25.6 GB/s. Both lack ECC support. The i7-4810MQ's PCIe implementation is noted as Gen 3, 16 Lanes (CPU only); the i5-4670K simply lists Gen 3.

Head-to-Head Benchmarks

The i7-4810MQ establishes its lead early in the Cinebench suite. In Cinebench R15 multi-core, the i7-4810MQ scores 516 against the i5-4670K's 478, a 7.4% gap. The single-core R15 result follows the same pattern: 72 versus 67, a 6.9% edge for the mobile chip. Moving to Cinebench R20, the i7-4810MQ posts 2154 multi-core and 304 single-core, beating the i5-4670K's 1995 and 281 by 7.4% and 7.6%, respectively. Cinebench R23 shows the most consistent margins of the entire comparison: the i7-4810MQ scores 5129 multi-core and 724 single-core, against 4751 and 670 for the i5-4670K. Both R23 deltas sit at 7.4% and 7.5%. The pattern is uniform — the i7-4810MQ outperforms by roughly 7% across every Cinebench iteration, regardless of core count or workload scaling.

The Geekbench results flip the script. The i5-4670K scores 3700 in multi-core, beating the i7-4810MQ's 3203 by a substantial 15.5%. In single-core, the i5-4670K posts 1302 against 1106, a 17.7% advantage. These are the largest margins in either direction across the entire head-to-head set. The i5-4670K wins two tests; the i7-4810MQ wins six. But the magnitude of the Geekbench wins is roughly double the magnitude of the Cinebench wins. The i7-4810MQ's Cinebench edge hovers in the 7% range, while the i5-4670K's Geekbench edge approaches 18%. This suggests the i5-4670K's higher base clock — 3.40 GHz versus 2.80 GHz — matters more in Geekbench's latency-sensitive workloads, while the i7-4810MQ's extra threads drive its Cinebench advantage.
