AMD Ryzen 5 4500U vs Intel Core i7-5775R Comparison

The AMD Ryzen 5 4500U and Intel Core i7-5775R represent two very different eras of processor design, yet they land in the same performance tier overall. The data shows both chips sit at the 45th percentile among all CPUs, with the Ryzen 5 4500U averaging a benchmark score of 2035 and the Core i7-5775R averaging 2031. That 0.2% gap in average score is negligible, but the individual benchmark results reveal starkly different strengths. The Ryzen 5 4500U wins three of the four head-to-head tests, while the Core i7-5775R takes one, and the margins vary from a narrow 6.9% to a decisive 93.3%.

Head-to-Head Benchmarks

The most lopsided result in this comparison comes from Cinebench R15 single-core testing. The AMD Ryzen 5 4500U scores 174, while the Intel Core i7-5775R manages only 90, giving AMD a 93.3% advantage. This is a massive gap in single-threaded performance, reflecting the generational leap between the Zen 2 architecture and the older Broadwell design. The Ryzen 5 4500U also leads in Cinebench R15 multi-core, scoring 892 against the Intel chip’s 641, a 39.2% margin. In that test, the Ryzen’s six cores and higher boost clock of 4.00 GHz prove decisive against the Intel part’s four cores and 3.80 GHz boost.

The single-core advantage persists in the newer Cinebench R23 benchmark, though the margin narrows. The Ryzen 5 4500U scores 1152, while the Core i7-5775R scores 897, giving AMD a 28.4% lead. This suggests that while the Broadwell architecture falls further behind in older workloads, it closes some of the gap in newer rendering tasks. The one win for Intel comes in Cinebench R23 multi-core, where the Core i7-5775R scores 6360 against the Ryzen 5 4500U’s 5920, a 6.9% advantage. This result is notable because it flips the multi-core narrative established by Cinebench R15. The Intel chip’s eight threads, via Hyper-Threading on four cores, appear to scale better in this particular workload, even though it has fewer physical cores.

Across the four head-to-head tests, the Ryzen 5 4500U’s wins are larger in aggregate. Its 93.3% and 39.2% margins in Cinebench R15 dwarf Intel’s 6.9% win in Cinebench R23 multi-core. The single-core delta of 28.4% in R23 further cements AMD’s overall dominance in this matchup, even as the average benchmark scores suggest near-parity. The data indicates the Ryzen 5 4500U is the stronger all-around performer, with the Core i7-5775R retaining a niche advantage in one specific multi-threaded workload.

FAQ

Q: Which processor has the higher single-core performance in Cinebench R23?

A: The AMD Ryzen 5 4500U scores 1152 in Cinebench R23 single-core, which is 28.4% higher than the Intel Core i7-5775R’s 897. This represents the largest modern single-threaded gap between the two, though it is smaller than the 93.3% delta seen in Cinebench R15 single-core.

Q: Does the Intel Core i7-5775R win any benchmark against the AMD Ryzen 5 4500U?

A: Yes. In Cinebench R23 multi-core, the Core i7-5775R scores 6360 versus 5920 for the Ryzen 5 4500U, a 6.9% advantage. This is the only head-to-head test where Intel comes out ahead, despite having fewer physical cores.

Q: How do the two processors compare in overall average benchmark score?

A: The AMD Ryzen 5 4500U has an average benchmark score of 2035, while the Intel Core i7-5775R averages 2031. This puts them within 0.2% of each other, and both occupy the 45th percentile among all CPUs.

Q: What is the core and thread configuration for each processor?

A: The AMD Ryzen 5 4500U has 6 cores and 6 threads, meaning no simultaneous multithreading. The Intel Core i7-5775R has 4 cores and 8 threads, using Hyper-Threading to double the thread count.

Q: Which processor has the higher boost clock speed?

A: The AMD Ryzen 5 4500U boosts up to 4.00 GHz, while the Intel Core i7-5775R boosts up to 3.80 GHz. However, the Intel chip has a higher base clock of 3.30 GHz compared to the AMD’s 2.30 GHz.

Q: Are both processors still in production?

A: No. The AMD Ryzen 5 4500U is listed as active in production, while the Intel Core i7-5775R is marked as end-of-life.

Architecture Differences

The two processors come from fundamentally different design philosophies and manufacturing eras. The AMD Ryzen 5 4500U is built on TSMC’s 7 nm process node, while the Intel Core i7-5775R uses Intel’s 14 nm node. This process advantage allows AMD to pack 9,800 million transistors into a 156 mm² die, whereas the Intel chip has a larger 182 mm² die with transistor count not specified in the data. The smaller node and denser transistor layout contribute to the Ryzen’s superior efficiency, as reflected in its 15 W TDP against the Intel part’s 65 W TDP.

Architecturally, the Ryzen 5 4500U uses Zen 2 under the codename Renoir, part of the 4000 series. The Core i7-5775R uses the older Broadwell architecture, which is also its codename. This generational gap is evident in the cache hierarchy. Both share 64 KB of L1 cache per core, but the Ryzen has 512 KB of L2 per core versus 256 KB on the Intel. For L3, the AMD part offers 8 MB shared, while the Intel has 6 MB shared. These larger caches on the Ryzen help explain its substantial single-core lead.

Memory support differs significantly. The Ryzen 5 4500U supports DDR4 and LPDDR4 memory over a dual-channel bus, delivering 51.2 GB/s of bandwidth. The Core i7-5775R is limited to DDR3, also dual-channel, but with only 29.9 GB/s of bandwidth. This 71% bandwidth advantage for AMD is another factor in its favor for memory-sensitive workloads. Neither processor supports ECC memory.

The integrated graphics also diverge. The Ryzen 5 4500U features Radeon Graphics with 384 shader processors, while the Intel part uses Iris Pro Graphics 6200. The Ryzen is a mobile-focused part on the AMD Socket FP6, whereas the Core i7-5775R is a desktop chip on Intel BGA 1364. PCIe support is similar in generation, with both offering Gen 3, but Intel provides 16 lanes versus AMD’s 12 lanes. The Ryzen 5 4500U was released on 2020-01-05, while the Core i7-5775R launched earlier on 2015-05-14. The Intel chip has a launch MSRP of $384; the AMD part has no listed launch MSRP.

The Verdict

The benchmark data points to a clear winner for most use cases. The AMD Ryzen 5 4500U takes three of four head-to-head tests, with its single-core performance being particularly dominant. A 93.3% lead in Cinebench R15 single-core and a 28.4% lead in Cinebench R23 single-core indicate that the Zen 2 architecture is vastly superior for lightly-threaded tasks. The Ryzen also wins multi-core in Cinebench R15 by 39.2%, showing that its six physical cores outperform the Intel’s four cores plus Hyper-Threading in that workload.

The Intel Core i7-5775R is not without merit, however. Its win in Cinebench R23 multi-core, by 6.9%, suggests that certain modern multi-threaded workloads can leverage its eight threads more effectively. The near-identical average benchmark scores, 2035 versus 2031, reinforce that neither chip is dramatically faster overall. Still, the Ryzen 5 4500U’s wins are larger in magnitude, and its active production status makes it a more viable option for current systems. The Core i7-5775R, being end-of-life, is a legacy part with a narrower appeal.

For users prioritizing single-threaded responsiveness or running older multi-threaded applications, the Ryzen 5 4500U is the better choice. For specific modern multi-threaded tasks where Cinebench R23 multi-core is representative, the Core i7-5775R holds a slight edge. The data does not support recommending the Intel chip as a general-purpose performer; its single win is too narrow and its losses too wide. The Ryzen 5 4500U is the stronger overall processor.
