Both CPUs sit at the 35th percentile among all CPUs, meaning they are in the lower-middle range of the database's recorded processors.

Architecture Differences

Both chips are built on Intel's Haswell architecture, but they are not identical underneath. The i5-4570R carries the codename Crystal Well, while the i5-4670R is plain Haswell. This distinction shows up in the physical design and feature set.

The process node is the same: 22 nm, fabricated by Intel. However, the transistor counts differ significantly. The i5-4570R packs 1,700 million transistors on a 260 mm² die, while the i5-4670R has 1,400 million transistors on a much smaller 177 mm² die. The extra transistors and larger die on the i5-4570R are tied to its Crystal Well design, which includes a larger integrated graphics solution. The i5-4570R features Intel Iris Pro 5200 graphics, while the i5-4670R lists Intel Iris? Pro 5200, with a question mark in the database indicating uncertainty about the exact graphics branding.

Core and cache configurations are identical: both have 4 cores and 4 threads, with 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 4 MB of shared L3 cache. Memory support is DDR3 on both, and neither supports ECC memory. The i5-4570R has a dual-channel memory bus with 25.6 GB/s bandwidth, while the i5-4670R does not have memory bus or bandwidth data recorded. The i5-4570R lists PCIe Gen 3 with 16 lanes (CPU only), while the i5-4670R has no PCIe data recorded.

Clock speeds are a major differentiator. The i5-4570R runs at 2.70 GHz base and 3.20 GHz boost, while the i5-4670R runs at 3.00 GHz base and 3.70 GHz boost. That 300 MHz base and 500 MHz boost advantage explains the consistent benchmark gap. Both have a 65 W TDP and use the Intel BGA 1364 socket.

One notable feature difference: the i5-4670R has an unlocked multiplier, while the i5-4570R does not. This means the i5-4670R can be overclocked, whereas the i5-4570R is locked. The i5-4570R has a part number of SR18P, while the i5-4670R has no part number recorded. The i5-4570R is marked as end-of-life production status, while the i5-4670R is listed as active. Both were released on the same date in June 2013.

The Verdict

The data points to a clear winner for any workload measured. The Intel Core i5-4670R is faster in every single benchmark recorded, with a consistent 12.8% to 14.3% advantage across Cinebench R15, R20, and R23, in both multi-core and single-core tests. The higher base clock of 3.00 GHz versus 2.70 GHz and boost clock of 3.70 GHz versus 3.20 GHz directly translate into that performance lead.

The i5-4670R also offers an unlocked multiplier, giving it an overclocking headroom that the locked i5-4570R cannot match. For anyone choosing between these two, the i5-4670R is the better pick on raw performance and flexibility.

The i5-4570R does have some compensating features. Its Crystal Well design includes a larger die and more transistors (1,700 million versus 1,400 million), which supports the Intel Iris Pro 5200 graphics. It also has recorded memory bandwidth of 25.6 GB/s and PCIe Gen 3 with 16 lanes, details that are missing for the i5-4670R. However, those features do not show up in the CPU benchmark scores.

The i5-4570R is end-of-life, while the i5-4670R remains active, which could matter for long-term availability. But from a pure performance standpoint, the i5-4670R wins every comparison. The 35th percentile ranking for both chips places them in the same overall performance tier, but within that tier, the i5-4670R is clearly the stronger part.

Where Each One Wins

The Intel Core i5-4670R wins in every measured CPU benchmark category. It outperforms the i5-4570R in multi-core Cinebench R15 (448 versus 390), R20 (1868 versus 1629), and R23 (4448 versus 3879). It also wins in single-core Cinebench R15 (63 versus 54), R20 (263 versus 229), and R23 (627 versus 547). This makes it the choice for any CPU-bound work, whether that is rendering, compiling, or general responsiveness.

The i5-4670R also wins on overclocking capability, since its multiplier is unlocked and the i5-4570R's is not. That gives the i5-4670R additional performance headroom beyond its already higher stock clocks. Its active production status also makes it the more available option going forward.

The Intel Core i5-4570R has no benchmark wins in the recorded data, but it does have some distinct advantages in its feature profile. Its Crystal Well design includes a larger die and more transistors, which likely supports a more robust integrated graphics solution (Intel Iris Pro 5200). It has documented memory bandwidth of 25.6 GB/s and PCIe Gen 3 with 16 lanes, while those fields are not recorded for the i5-4670R. For a system relying heavily on the integrated GPU, the i5-4570R's graphics capabilities may be the deciding factor, though the database does not include iGPU benchmark scores to confirm this.

For pure CPU compute, the choice is simple: the i5-4670R is faster in every test. For a compact, BGA-based system where integrated graphics matter more than raw CPU speed, the i5-4570R's Crystal Well design and larger transistor budget could make it a more balanced part. But based strictly on the recorded benchmark data, the i5-4670R is the superior processor.
