Where Each One Wins

The head-to-head benchmark set is split evenly. The AMD Ryzen 7 3750H takes cinebench R15 multi-core, cinebench R15 single-core, and cinebench R23 single-core. The Intel Core i5-4670K wins cinebench R23 multi-core, Geekbench multi-core, and Geekbench single-core.

A closer look at the margin in each win shows the AMD part's advantages are mostly in the older Cinebench R15 suite and in single-core R23. The largest AMD win is in cinebench R15 single-core, where it scores 144 against the Intel's 67, a 114.9% advantage. The largest Intel win is in cinebench R23 multi-core, where it scores 4751 versus 3897, a 18% lead.

Architecture Differences

The Ryzen 7 3750H is built on a 12 nm process at GlobalFoundries, with 4,940 million transistors on a 210 mm² die. It uses the Zen+ microarchitecture, codenamed Picasso. The Core i5-4670K uses Intel's 22 nm process, with 1,400 million transistors on a 177 mm² die, and is based on the Haswell architecture.

The cache layouts show the different design goals of the two chips. The AMD chip provides 96 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3. The Intel chip provides 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3. The AMD part has a larger L1 and L2 per core, while the Intel chip has a larger shared L3 pool.

The integrated graphics also differ. The AMD Ryzen 7 3750H includes Radeon Vega 10 graphics, while the Intel Core i5-4670K includes Intel HD 4600 graphics. Both support DDR4 and DDR3 respectively, and both use a dual-channel memory bus.

Specification Differences

The two processors differ in several key specification fields. The AMD Ryzen 7 3750H is a mobile processor with a base clock of 2.30 GHz and a boost clock of 4.00 GHz, with a TDP of 35 W. The Intel Core i5-4670K is a desktop chip with a base clock of 3.40 GHz and a boost of 3.80 GHz, with a TDP of 84 W.

The AMD part is a Socket FP6 chip with a 12 nm process. The Intel part is a Socket 1150 chip with a 22 nm process. The AMD supports DDR4 memory, while the Intel supports DDR3. Both use dual-channel memory buses.

The Ryzen 7 3750H integrates Radeon Vega 10 graphics. The Core i5-4670K integrates Intel HD 4600.

Head-to-Head Benchmarks

The Cinebench R15 multi-core test shows the AMD Ryzen 7 3750H with a score of 734, which is 53.6% higher than the 478 scored by the Core i5-4670K. In R15 single-core, the Ryzen 7 3750H scores 144, a 114.9% lead over the 67 of the Intel chip.

Cinebench R23 flips the multi-core result. Here, the Intel Core i5-4670K scores 4751 versus the AMD Ryzen 7 3750H's 3897, an 18.0% margin for the desktop part. The single-core R23 test returns to the AMD side: the Ryzen 7 3750H scores 971, which is 44.9% higher than the Intel's 670.

Geekbench multi-core continues the Intel trend, with the Core i5-4670K scoring 3700 versus 3446 for the Ryzen 7 3750H, a 6.9% margin. The single-core Geekbench goes back to Intel, with the i5-4670K scoring 1302 against 950 for the AMD Ryzen, a 27.0% difference.

The scoreboard is balanced at three wins each. The AMD Ryzen 7 3750H has a larger boost clock, higher single-core performance in both Cinebench suites, and a higher power efficiency. The Intel Core i5-4670K has a higher base clock and a larger shared L3 cache, and wins the multi-core R23 and both Geekbench tests. These scores indicate that the modern mobile AMD chip closes much of the generational performance gap, while the desktop Intel chip retains advantages in multi-threaded workloads and classic IPC, despite its older architecture.
