Intel Core i3-1005G1 vs Intel Core i5-3570 Comparison

The Intel Core i5-3570 and Intel Core i3-1005G1 represent two very different eras of Intel silicon: a 2012 desktop quad-core versus a 2019 mobile dual-core. Benchmark results show a clear split: the older i5 dominates multi-threaded workloads, while the newer i3 takes a decisive lead in single-threaded Geekbench performance. Data from the FACT PACK shows the i5-3570 wins 7 of 8 head-to-head tests, but the one loss is substantial.

Head-to-Head Benchmarks

The i5-3570’s advantage is most pronounced in Geekbench multicore, where it scores 2251 against the i3-1005G1’s 1978 — a 13.8% lead. This is the largest delta in either direction across all tests. The margin shrinks in Cinebench suites: the i5 leads by 2.7% in R15 multicore (421 vs 410), 2.9% in R20 multicore (1758 vs 1709), and 2.9% in R23 multicore (4187 vs 4070). These are consistent, if modest, wins. The pattern is clear: the i5’s four physical cores give it a structural edge in parallel workloads, even against a newer architecture.

Single-core Cinebench results tell a similar story, with the i5 ahead by 3.5% in R15 (59 vs 57), 2.9% in R20 (248 vs 241), and 3% in R23 (591 vs 574). These are small but repeatable margins. The i5-3570’s 3.80 GHz boost clock, combined with its older but higher-power design, keeps it competitive in lightly threaded tasks within the Cinebench suite.

The one reversal is dramatic. In Geekbench single-core, the i3-1005G1 scores 1083 versus the i5’s 770, a 28.9% advantage for the i3. This is a massive swing, far exceeding any other delta in the comparison. It reflects the generational leap in IPC (instructions per clock) from Ivy Bridge to Ice Lake. The i3’s 10 nm process and Sunny Cove architecture extract far more performance per clock, even at a much lower 1200 MHz base clock. The i5’s higher boost clock of 3.80 GHz cannot compensate for the architectural deficit in this specific test.

The average benchmark scores place both processors at the 35th percentile of all CPUs, with the i5 averaging 1286 and the i3 averaging 1265. The i5’s nearest rivals include the Intel Core i5-4670R (deltaPct 0), AMD Opteron 6272 (deltaPct -0.1), and Intel Core i7-3630QM (deltaPct -0.3). The i3’s nearest rivals include the Intel Xeon W-2102 (deltaPct 0.1) and AMD Athlon 200GE (deltaPct 0.4). Both chips sit in the same performance tier overall, but their strengths are distributed very differently.

The Verdict

From the data, the Intel Core i5-3570 is the better choice for multi-threaded desktop workloads. It wins every Cinebench multicore test and the Geekbench multicore test, with deltas ranging from 2.7% to 13.8%. Anyone running applications that scale across cores — video encoding, 3D rendering, compilation — will see a measurable benefit from the i5’s four cores.

The Intel Core i3-1005G1 is the pick for single-threaded Geekbench performance, where it is 28.9% faster. Its 10 nm architecture delivers superior per-core efficiency, which matters for lightly threaded tasks that rely on raw IPC. However, this advantage does not appear in the Cinebench single-core tests, where the i5 still holds a 3% edge.

If you are constrained to one of these two platforms, the decision hinges on workload. The i5-3570 is a desktop part with a 77 W TDP, socketed in Intel Socket 1155, and is end-of-life. The i3-1005G1 is a mobile part with a 15 W TDP, soldered in Intel BGA 1526, and is still active. The i5 is for a builder with an existing LGA 1155 board; the i3 is for a laptop or compact mobile system. The benchmark data favors the i5 for all-around productivity, but the i3’s single-core lead is too large to ignore for specific use cases.

Specification Differences

The two processors differ sharply in core count, clock speeds, power, and platform. The i5-3570 has 4 cores and 4 threads, with a base clock of 3.40 GHz and a boost clock of 3.80 GHz. The i3-1005G1 has 2 cores and 4 threads, with a base clock of 1200.00 MHz and a boost clock of 3.40 GHz. The i5 has a TDP of 77 W, while the i3 has a TDP of 15 W — a five-fold difference in power envelope.

The i5 uses Intel Socket 1155 and is a desktop part, while the i3 uses Intel BGA 1526 and is a mobile part. The i5 supports DDR3 memory with dual-channel bandwidth of 25.6 GB/s; the i3 supports DDR4 with dual-channel bandwidth of 51.2 GB/s. This gives the i3 double the memory bandwidth. The i5 has 16 PCIe Gen 3 lanes (CPU only), while the i3 lists PCIe Gen 3 without a lane count. The i5’s integrated graphics are Intel HD 2500; the i3’s are UHD Graphics. The i5 was released in 2012 and is end-of-life; the i3 was released in 2019 and is active. The i5 has a launch MSRP of $194; the i3 has no listed launch MSRP.

Architecture Differences

The architectural gap spans three nodes and seven years. The i5-3570 is built on Intel’s 22 nm process with 1,400 million transistors and a die size of 160 mm². Its architecture is Ivy Bridge, with a codename of Ivy Bridge. The i3-1005G1 uses the 10 nm process with a die size of 123 mm², based on the Ice Lake architecture with the codename Ice Lake-U. The i3’s transistor count is not listed.

Cache layouts differ as well. Both have 64 KB L1 per core and 256 KB L2 per core, but the i5 has 6 MB of shared L3 cache, while the i3 has 4 MB of shared L3 cache. The i3’s smaller cache is partially offset by its newer architecture.

The generation labels confirm the divide: the i5 is Core i5 (Ivy Bridge), while the i3 is Core i3 (Sunny Cove-U). Both have locked multipliers. The i5’s part number is SR0T7; the i3’s is SRG0SSRGKF. Neither supports ECC memory.

Where Each One Wins

The Intel Core i5-3570 is the clear winner for multi-threaded desktop applications. Its 13.8% lead in Geekbench multicore and consistent 2.7–2.9% margins in all Cinebench multicore tests make it the better option for rendering, encoding, and any workload that uses all available cores. Its 77 W TDP and desktop socket indicate a system designed for sustained performance, not battery life.

The Intel Core i3-1005G1 wins decisively in Geekbench single-core, with a 28.9% advantage. This makes it the better choice for applications that are heavily dependent on a single thread and benefit from the newer Sunny Cove architecture’s higher IPC. Its 15 W TDP and mobile socket also make it the only viable choice for a thin-and-light laptop. The i3’s 51.2 GB/s memory bandwidth, double the i5’s 25.6 GB/s, is another area where the newer part pulls ahead, even if benchmark scores do not directly isolate this.

In practical terms: the i5-3570 is for a fixed desktop build where multi-core throughput matters and power draw is not a concern. The i3-1005G1 is for a portable system where single-threaded responsiveness and efficiency are priorities. The benchmark data supports the i5 as the overall faster processor in 7 out of 8 tests, but the i3’s single-core dominance is a critical caveat for specific software.
