AMD Ryzen 3 PRO 2300U vs Intel Core i5-4670 Comparison

The Verdict

The recorded data shows a consistent, if modest, advantage for the AMD Ryzen 3 PRO 2300U across every measured Cinebench workload. It wins all six head-to-head benchmark comparisons, with margins ranging from 1.5% to 2.5%. The Intel Core i5-4670, while a capable desktop part from the Haswell generation, trails in every single test.

The Ryzen 3 PRO 2300U is the clear pick for anyone prioritizing raw Cinebench performance, especially given its mobile market segment and 15 TDP. The data shows it delivers higher multi-core and single-core scores while drawing significantly less power. The Intel part, with its 84 TDP and desktop socket, offers no performance advantage in these tests; its only redeeming feature is its older platform, which may appeal to those with existing Socket 1150 motherboards.

For a new build, the database points squarely at the Ryzen. For an upgrade on an existing Haswell platform, the i5-4670 remains a functional option, but it is not the faster part. The verdict is straightforward: the AMD Ryzen 3 PRO 2300U is the superior processor based on the available benchmark data.

Architecture Differences

The two processors come from different architectural eras and design philosophies. The Intel Core i5-4670 uses the Haswell architecture, built on a 22 nm process at Intel's foundry. It packs 1,400 million transistors on a 177 mm² die. In contrast, the AMD Ryzen 3 PRO 2300U uses the Zen architecture, codenamed Raven Ridge, built on a 14 nm process at GlobalFoundries. This newer process allows AMD to fit 4,950 million transistors on a 210 mm² die, a much denser and more complex chip.

Both have 4 cores and 4 threads, so there is no difference in raw core count. Cache configurations, however, differ. The Intel chip has 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3 cache. The AMD chip has 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The AMD part has more L1 and L2 per core, but less shared L3.

Memory support also separates them. The i5-4670 supports DDR3 with a dual-channel bus. The Ryzen 3 PRO 2300U supports DDR4 with a dual-channel bus and a recorded memory bandwidth of 38.4 GB/s. The integrated graphics differ: Intel uses HD 4600, while AMD uses Radeon Vega 6. The AMD part also offers PCIe Gen 3 with 8 lanes (CPU only), while the Intel part lists PCIe Gen 3 without a lane count. The Ryzen is a mobile part on Socket FP5, while the Intel is a desktop part on Socket 1150. The Intel chip is not multiplier unlocked, and neither processor supports ECC memory.

Where Each One Wins

The head-to-head benchmark data is unambiguous: the AMD Ryzen 3 PRO 2300U wins every recorded test. There are no benchmark wins for the Intel Core i5-4670 in the database. The AMD part takes all six Cinebench tests, both multi-core and single-core, across R15, R20, and R23 versions.

This means in pure compute workloads, the Ryzen is the better choice. For multi-threaded tasks like rendering, the Ryzen leads by 2.2% to 2.3% in R20 and R23 multicore tests, and by 2.3% in R15 multicore. For single-threaded tasks, the margins are similar: 1.5% in R15, 2.5% in R20, and 2.4% in R23, all favoring AMD.

The Intel part's only potential advantage is platform-level, not performance-level. It is a desktop processor with a higher TDP (84 versus 15), suggesting it may sustain boost clocks longer under sustained loads in a desktop chassis with adequate cooling. However, the recorded benchmarks do not show any such advantage; the data shows AMD winning all tests. For those with an existing LGA 1150 motherboard, the i5-4670 is a drop-in option, but the measured performance is consistently lower.
