Intel Core i5-4570R vs Intel Core i5-8365UE Comparison

Head-to-Head Benchmarks

The benchmark data presents a consistent and unambiguous picture: the Intel Core i5-8365UE wins every recorded head-to-head comparison, taking all six tests in the database. The Intel Core i5-4570R does not record a single victory in any of the measured workloads.

In Cinebench R15 multicore, the i5-8365UE scores 474 against the i5-4570R's 390, a delta of -17.7% from the perspective of the older chip. The single-core R15 test shows a similar gap: 66 versus 54, a -18.2% delta. Moving to Cinebench R20, the i5-8365UE posts 1978 multicore and 279 single-core, while the i5-4570R manages 1629 and 229 respectively, with deltas of -17.6% and -17.9%. Cinebench R23 repeats the pattern: 4710 versus 3879 in multicore (-17.6%) and 665 versus 547 in single-core (-17.7%).

The consistency of these deltas, all clustering between -17.6% and -18.2%, suggests a uniform performance advantage rather than workload-specific strengths. The i5-8365UE is not merely faster in one type of application; it maintains roughly an 18% lead across every rendering benchmark recorded.

The average benchmark score in the database reinforces this. The i5-8365UE sits at 1362, while the i5-4570R averages 1318. That places the newer chip in the 36th percentile of all CPUs tracked, versus the 35th percentile for the older part. The nearest rivals for the i5-8365UE include the Intel Core i5-6500T at an identical 1362 (delta 0%), the Intel Core i7-3820QM at 1366 (-0.3%), and the Intel Xeon D-1521 at 1367 (-0.4%). The i5-4570R's closest comparators include the Intel Celeron G6900E at 1321 (-0.2%), the Intel Celeron G6900T at 1321 (-0.2%), the Intel Core i7-3770T at 1314 (0.3%), and the AMD Athlon Gold 7220U at 1311 (0.5%).

The single-core advantage is particularly notable given the architectural differences. The i5-8365UE achieves a 21.6% higher single-core R23 score (665 vs 547) despite being a 15W mobile part. This indicates that IPC improvements in the Whiskey Lake architecture are substantial enough to overcome the power envelope disadvantage.

Architecture Differences

The two processors come from different eras and design philosophies. The Intel Core i5-4570R uses the Haswell architecture, codenamed Crystal Well, built on a 22 nm process with 1,700 million transistors on a 260 mm² die. It belongs to the Core i5 Haswell generation. The Intel Core i5-8365UE, in contrast, uses the Whiskey Lake architecture, codenamed Whiskey Lake-U, built on a 14 nm process. Its transistor count and die size are not recorded in the database.

Both chips have 4 physical cores. The critical difference lies in threading: the i5-4570R supports 4 threads total, while the i5-8365UE supports 8 threads through Hyper-Threading. This doubling of thread count partially explains the multicore performance gap, although the single-core lead shows the newer architecture also improves per-thread efficiency.

Cache configurations also differ. Both share 64 KB of L1 cache per core and 256 KB of L2 per core. The L3 cache, however, is 4 MB shared on the i5-4570R versus 6 MB shared on the i5-8365UE. That 50% increase in last-level cache gives the newer part more room for frequently accessed data.

Memory support diverges as well. The i5-4570R uses DDR3 with dual-channel support and a recorded memory bandwidth of 25.6 GB/s. The i5-8365UE uses DDR4, also dual-channel, but with a substantially higher memory bandwidth of 38.4 GB/s. That represents a 50% improvement in theoretical bandwidth, which can benefit memory-intensive workloads.

The integrated graphics differ significantly. The i5-4570R carries Intel Iris Pro 5200, a higher-end GPU for its era, while the i5-8365UE uses UHD Graphics 620. The database does not record benchmark scores for these iGPUs, so direct comparison is not possible from the available data.

The power envelopes are dramatically different. The i5-4570R has a TDP of 65W, typical of a desktop-class part, while the i5-8365UE is rated at 15W, a mobile ultra-low-power design. The i5-8365UE achieves its performance lead despite consuming less than a quarter of the power budget. This speaks to the efficiency gains from the 14 nm process and architectural refinements.

Both processors use the same PCIe configuration: Gen 3 with 16 lanes, CPU only. Neither supports ECC memory. Both have locked multipliers, meaning no overclocking from the user. The sockets differ: the i5-4570R uses Intel BGA 1364, while the i5-8365UE uses Intel BGA 1528, so they are not interchangeable in any system.

The market segments reflect their intended use cases. The i5-4570R is classified as a desktop part, released on 2013-06-01 and now end-of-life. The i5-8365UE is a mobile part, released on 2019-04-15 and still active in production. The i5-8365UE carries a launch MSRP of $297, while the i5-4570R has no recorded launch MSRP.

The Verdict

The data points to a clear winner for almost any workload: the Intel Core i5-8365UE. It wins all six head-to-head benchmarks, achieves a higher average score (1362 vs 1318), and sits at a higher percentile of all CPUs (36th vs 35th). The performance gap is consistent across single-core and multicore tests, with deltas ranging from -17.6% to -18.2%.

The i5-8365UE achieves this while consuming 15W versus 65W, making it the superior choice for any power-constrained system. It also supports newer DDR4 memory with 38.4 GB/s bandwidth versus 25.6 GB/s, has 6 MB of L3 cache versus 4 MB, and offers 8 threads versus 4. Every measurable specification favors the newer chip except for the integrated graphics, where the Iris Pro 5200 may offer different capabilities than UHD Graphics 620, though no benchmark data exists in the database to quantify this.

The i5-4570R is a legacy desktop part from 2013, now end-of-life. Its only advantages are historical: it belongs to a different era of Intel's product line and uses an older socket. For a user building or maintaining a system around the BGA 1364 socket, the i5-4570R remains a functional 4-core processor. But for anyone choosing between these two CPUs for a new system, the i5-8365UE is the rational selection based on the recorded performance data.

Those who must stick with the i5-4570R, perhaps due to an existing motherboard or thermal constraints in a legacy chassis, should note that it still performs in the same general range as the Intel Core i7-3770T (0.3% delta) and the AMD Athlon Gold 7220U (0.5% delta). It is not an unusable chip, but it is measurably behind the i5-8365UE in every recorded test.
