Intel Core i5-5675R vs Intel Core i7-8560U Comparison

The Intel Core i5-5675R and Intel Core i7-8560U are both 14nm quad-core Intel parts, but they serve completely different market segments. The i5-5675R is a desktop Broadwell chip with a 65W TDP, while the i7-8560U is a Whiskey Lake mobile processor with a 15W TDP. Despite the power envelope discrepancy, the benchmark data shows a clear performance hierarchy, with the newer, lower-power mobile chip winning every single head-to-head test. The i7-8560U leads by a consistent margin of roughly 16% across all Cinebench workloads, making it the stronger processor in raw compute, even though it was designed for thin-and-light laptops.

Head-to-Head Benchmarks

The head-to-head results are unambiguous: the Intel Core i7-8560U wins all six benchmark comparisons. In Cinebench R15 multicore, the i7-8560U scores 568 against the i5-5675R's 476, a delta of -16.2% for the i5. The single-core R15 test shows the same pattern: 80 for the i7 versus 67 for the i5, again a -16.2% difference. These are not narrow victories; the mobile chip holds a substantial lead in both threaded and lightly-threaded workloads.

Moving to Cinebench R20, the gap remains nearly identical. The i7-8560U posts 2369 in multicore, while the i5-5675R manages 1987, a -16.1% delta. Single-core R20 sees the i7 at 334 and the i5 at 280, a -16.2% margin. The consistency of these deltas across different Cinebench versions suggests the performance difference is structural rather than workload-specific. It is not a matter of one test favoring a particular feature; the i7-8560U is simply faster across the board.

The latest Cinebench R23 results reinforce this narrative. In multicore, the i7-8560U scores 5641 versus the i5-5675R's 4733, a -16.1% delta. Single-core R23 shows 796 for the i7 and 668 for the i5, a -16.1% gap. The R23 numbers are particularly telling because they represent the most modern and demanding workload in the data set. Even with the i5's desktop-class 65W TDP, it cannot overcome the architectural and clock speed advantages of the i7-8560U.

It is importantly the i5-5675R has Geekbench results in the data — 3738 multicore and 1234 single-core — but the i7-8560U does not have corresponding Geekbench scores, so those cannot be compared directly. The Cinebench suite, however, provides a complete picture, and it is uniformly favorable to the i7-8560U. The i5-5675R wins zero head-to-head tests, while the i7-8560U takes all six.

The Verdict

The data points to one conclusion: the Intel Core i7-8560U is the superior processor in every benchmark measured. It outperforms the i5-5675R by approximately 16% in both single-core and multi-core Cinebench R15, R20, and R23 tests. This is a decisive and consistent victory, not a marginal one. Anyone choosing between these two strictly on performance should select the i7-8560U, regardless of the fact that it is a mobile chip with a lower TDP.

That said, the i5-5675R is not without its own context. It sits in the 40th percentile of all CPUs, with an average benchmark score of 1648. Its nearest rivals include the Intel Core i7-4810MQ (avg score 1651, delta -0.2%), Intel Core i7-5700HQ (avg score 1645, delta 0.2%), AMD Opteron 6380 (avg score 1643, delta 0.3%), and AMD Ryzen 5 3550H (avg score 1653, delta -0.3%). These are all very close scores, meaning the i5-5675R is essentially on par with a range of older high-end mobile and desktop chips. The i7-8560U, by contrast, sits in the 39th percentile with an average score of 1631, and its nearest rivals include the Intel Xeon E5-2623 v3 (avg score 1630, delta 0.1%), Intel Pentium Gold G7400T (avg score 1628, delta 0.2%), AMD Ryzen 3 PRO 2200G (avg score 1640, delta -0.6%), and Intel Core i3-9100T (avg score 1620, delta 0.7%).

Interestingly, despite the i7-8560U winning every head-to-head, its average benchmark score (1631) is actually slightly lower than the i5-5675R's (1648). This is because the average includes the Geekbench results that only the i5 has, which skew its average upward. The head-to-head Cinebench data is the more reliable comparison, and it clearly favors the i7-8560U.

Architecture Differences

The two processors come from different generations and design philosophies. The i5-5675R is based on the Broadwell architecture, released in 2015, and uses the Intel BGA 1364 socket. It is a desktop part with a 65W TDP. The i7-8560U is based on Whiskey Lake, released in 2018, and uses the Intel BGA 1528 socket. It is a mobile part with a much lower 15W TDP, designed for ultraportable laptops.

Both CPUs have 4 physical cores, but the i7-8560U supports 8 threads via Hyper-Threading, while the i5-5675R has only 4 threads. This is a significant architectural difference that partially explains the multicore performance gap. The i7 also has a much higher boost clock: 4.60 GHz compared to the i5's 3.60 GHz. The base clocks are also very different, with the i5 at 3.10 GHz and the i7 at 1800.00 MHz (1.80 GHz), but the i7's boost clock is what matters for real-world performance.

Cache configurations differ as well. Both have 64 KB L1 and 256 KB L2 per core, but the i7-8560U has 8 MB of shared L3 cache, double the i5-5675R's 4 MB. The i7 also supports both DDR3 and DDR4 memory, while the i5 only supports DDR3. Memory bandwidth is higher on the i7 at 38.4 GB/s versus 29.9 GB/s on the i5. The integrated graphics differ too: the i5 has Iris Pro Graphics 6200, while the i7 has UHD Graphics 620.

The process node is the same for both — 14nm from Intel — but the die size is only listed for the i5 at 182 mm². The i7's die size is not provided. The i5 is marked as "Active" production status, while the i7 is "End-of-life." The i5 has a launch MSRP of $265, which can be stated once as the launch MSRP, but the i7 has no launch MSRP listed.

Where Each One Wins

The Intel Core i7-8560U wins in every performance category measured. It is faster in single-core and multi-core workloads across Cinebench R15, R20, and R23. This makes it the clear choice for any application that depends on raw CPU throughput, whether that is rendering, encoding, or general productivity. Its 4.60 GHz boost clock and 8 threads give it a decisive edge in both lightly-threaded and heavily-threaded tasks.

The i5-5675R's only advantages are contextual rather than performance-based. It has a higher TDP of 65W, which means it is designed for desktop systems where power draw is less of a concern. It is also in "Active" production status, suggesting it may still be available for purchase, whereas the i7-8560U is end-of-life. The i5 also has a larger die size (182 mm²) and a launch MSRP of $265, though the i7 has no listed MSRP for comparison.

For a desktop builder who needs a CPU that is still in production and has a specific socket (Intel BGA 1364), the i5-5675R is the only option of the two. But for anyone who can use the i7-8560U's mobile platform (Intel BGA 1528), the performance data is unambiguous: the i7 is faster by a consistent 16% margin. The i7 also offers more L3 cache (8 MB vs 4 MB), higher memory bandwidth, and support for DDR4 memory.
