Intel Core i3-1005G1 vs Intel Core i5-4670R Comparison

The Intel Core i5-4670R and the Intel Core i3-1005G1 occupy the same performance percentile, but they achieve it through radically different designs. The data is unambiguous: across all six shared Cinebench tests, the older Haswell-based i5-4670R wins every single comparison, with a consistent margin of roughly 9-10% over the Ice Lake-based i3-1005G1. However, the i3-1005G1 counters with a drastically lower 15W TDP, a newer 10nm process, and support for modern DDR4 memory, making the choice a stark trade-off between raw compute and platform efficiency.

Head-to-Head Benchmarks

The benchmark results show a clear and consistent pattern of victory for the i5-4670R. In the Cinebench R15 multicore test, the i5-4670R scores 448 against the i3-1005G1's 410, a 9.3% advantage. The single-core test tells a similar story, with the i5-4670R at 63 versus 57 for the i3-1005G1, marking a 10.5% lead — the largest single-test margin in the comparison.

The trend holds across newer benchmark versions. In Cinebench R20 multicore, the i5-4670R posts 1868 while the i3-1005G1 manages 1709, again a 9.3% delta. The single-core R20 results show 263 against 241, a 9.1% edge for the i5-4670R. Moving to Cinebench R23, the multicore scores are 4448 for the i5-4670R and 4070 for the i3-1005G1, maintaining the exact 9.3% advantage seen in both R15 and R20 multicore tests. The R23 single-core test rounds out the sweep with 627 versus 574, a 9.2% difference.

The consistency of these deltas is notable. Across six benchmarks, the winning margin never deviates far from the 9-10% band, indicating that the performance gap is structural rather than workload-specific. The i5-4670R's four physical cores give it a sustained advantage over the i3-1005G1's two cores, even though both parts support four threads. The i3-1005G1's higher base clock of 1200 MHz is misleading, as the i5-4670R's 3.00 GHz base and 3.70 GHz boost clock provide substantially higher sustained throughput.

The average benchmark scores reflect this overall picture. The i5-4670R carries an average score of 1286, placing it in the 35th percentile of all CPUs, with its closest rival being the Intel Core i5-3570 at a 0% delta. The i3-1005G1's average score of 1265 also lands in the 35th percentile, with its nearest rival being the Intel Xeon W-2102 at a 0.1% delta. This means that despite the i5-4670R winning every head-to-head test, the two processors are statistically adjacent in the broader CPU landscape, separated by less than 2% in average score.

Architecture Differences

The architectural gulf between these two processors is enormous, spanning six years of Intel design evolution. The i5-4670R is built on the Haswell architecture using a 22nm process node, fabricated by Intel with 1,400 million transistors on a 177 mm² die. It features four cores and four threads, with a base clock of 3.00 GHz and a boost clock of 3.70 GHz. Its thermal design power is 65W, and it uses the Intel BGA 1364 socket. Memory support is limited to DDR3, and the integrated graphics are Intel Iris Pro 5200.

The i3-1005G1 represents a much newer design based on the Ice Lake architecture, specifically the Sunny Cove-U core generation. It is manufactured on a 10nm process node, also by Intel, with a smaller 123 mm² die size — the transistor count is not listed. It has only two cores but still supports four threads via Hyper-Threading. Its base clock is listed as 1200.00 MHz (effectively 1.20 GHz), with a boost clock of 3.40 GHz. The TDP is dramatically lower at 15W, suited for mobile platforms, and it uses the Intel BGA 1526 socket. Memory support is DDR4 with dual-channel operation and a memory bandwidth of 51.2 GB/s. It also features PCIe Gen 3 support and integrated UHD Graphics.

The cache hierarchy is one area where the two chips align. Both have 64 KB of L1 cache per core and 256 KB of L2 cache per core, and both share 4 MB of L3 cache. This means the i3-1005G1's two cores get the same total L3 capacity as the i5-4670R's four cores, giving the newer chip a per-core cache advantage despite its lower core count.

The multiplier status also differs: the i5-4670R has an unlocked multiplier, while the i3-1005G1 is locked. Neither processor supports ECC memory, and both carry a production status of "Active." The i5-4670R was released in 2013, while the i3-1005G1 arrived in 2019, and the i3-1005G1 has a listed part number of SRG0SSRGKF.

The Verdict

The data points to a straightforward conclusion for raw performance: the Intel Core i5-4670R is the faster processor in every measured benchmark. Its four physical cores deliver a consistent 9-10% advantage over the i3-1005G1 across all Cinebench versions, and its average benchmark score of 1286 tops the i3-1005G1's 1265. For anyone prioritizing compute throughput in multi-threaded applications, the i5-4670R is the clear choice.

However, the i3-1005G1's case rests entirely on efficiency and platform modernity. Its 15W TDP is less than a quarter of the i5-4670R's 65W TDP, a massive difference for mobile or compact systems. The 10nm process node and DDR4 memory support make it a more future-proof platform, and its smaller 123 mm² die suggests lower manufacturing costs per unit. The i3-1005G1 also adds PCIe Gen 3 support, which the i5-4670R lacks entirely.

The percentile data adds nuance. Both chips sit at the 35th percentile, and their average scores are within 2% of each other. The i5-4670R's nearest rival is the Intel Core i5-3570 at a 0% delta, while the i3-1005G1's nearest rival is the Intel Xeon W-2102 at 0.1%. This suggests that in the broader market, these processors are peers, and the choice between them should be driven by platform requirements rather than a quest for raw performance supremacy.

Specification Differences

The two processors differ in nearly every fundamental specification. The i5-4670R has 4 cores and 4 threads, while the i3-1005G1 has 2 cores and 4 threads. Base clocks are 3.00 GHz versus 1200.00 MHz, and boost clocks are 3.70 GHz versus 3.40 GHz. TDP is 65W versus 15W. The sockets are Intel BGA 1364 and Intel BGA 1526, respectively. Architecture names are Haswell versus Ice Lake, with codenames Haswell and Ice Lake-U. The process nodes are 22nm and 10nm. Die sizes are 177 mm² and 123 mm². Transistor counts are 1,400 million versus not listed.

Memory support differs: DDR3 for the i5-4670R, DDR4 for the i3-1005G1. The i3-1005G1 lists dual-channel memory with 51.2 GB/s bandwidth, while the i5-4670R has no listed memory bus or bandwidth. PCIe support appears only on the i3-1005G1 as Gen 3. Integrated graphics are Intel Iris Pro 5200 versus UHD Graphics. The i5-4670R has an unlocked multiplier, while the i3-1005G1 is locked. Release dates are 2013-06-01 and 2019-07-31. The i3-1005G1 has a part number (SRG0SSRGKF), while the i5-4670R does not. Market segments are Desktop versus Mobile.

Where Each One Wins

The i5-4670R wins decisively in all measured performance categories. It dominates every Cinebench test, from R15 single-core at 63 versus 57 to R23 multi-core at 4448 versus 4070. Its four physical cores provide a structural advantage that the i3-1005G1's two cores cannot overcome, even with equal thread counts. The unlocked multiplier on the i5-4670R also opens the door for overclocking, which the locked i3-1005G1 cannot offer. For desktop users with access to a 65W TDP budget and DDR3 memory, the i5-4670R is the stronger compute engine.

The i3-1005G1 wins in efficiency and platform features. Its 15W TDP makes it suitable for thin-and-light laptops or passively cooled systems where the i5-4670R's 65W envelope would be prohibitive. The 10nm process node represents a significant manufacturing advantage, and the 51.2 GB/s memory bandwidth of its DDR4 support is a generational leap over the i5-4670R's DDR3. PCIe Gen 3 support and a smaller 123 mm² die size further reinforce its position as the more modern, mobile-oriented part. The i3-1005G1 also has a later release date of 2019, meaning longer potential software support and driver optimization cycles.

In short, the i5-4670R wins on every benchmark score, while the i3-1005G1 wins on every efficiency metric. The choice depends entirely on whether the user needs maximum compute performance or maximum power efficiency and platform longevity.
