AMD Ryzen 5 7520U vs Intel Core i7-5775R Comparison

Head-to-Head Benchmarks

The benchmark data splits evenly at three wins apiece, but the margins tell a more nuanced story. The AMD Ryzen 5 7520U dominates in Cinebench R15 and Cinebench R23 single-core tests, while the Intel Core i7-5775R takes the newer multi-core workloads and both Geekbench tests. The biggest single gap is in Cinebench R15 single-core, where the AMD part scores 168.8 against Intel’s 90, a 87.6% advantage. That is a massive generation-leap effect. The AMD processor also leads Cinebench R15 multi-core by 30.1%, scoring 834 versus 641, and Cinebench R23 single-core by 30.5%, scoring 1171 against 897.

The Intel chip fights back in Cinebench R23 multi-core, where it scores 6360 versus AMD’s 5149, a 19% deficit for the AMD part. Geekbench results favor Intel as well, but by smaller margins: 3996 versus 3766 in multi-core (5.8% ahead) and 1218 versus 1185 in single-core (2.7% ahead). The pattern is clear. The AMD Ryzen 5 7520U wins decisively in older Cinebench versions and single-threaded R23, while the Intel Core i7-5775R wins the modern multi-threaded Cinebench R23 and both Geekbench tests, though with narrower deltas in Geekbench.

The average benchmark score for the AMD part is 2046, while the Intel part sits at 2031. Both CPUs land at the 45th percentile among all CPUs in the database. The AMD chip’s nearest rivals include the Intel Xeon E3-1270 v5 at 2048 (0.1% behind AMD), the Intel Core i7-7820HK at 2048 (0.1% behind), the Intel Xeon E3-1275 v5 at 2043 (0.1% ahead of AMD), and the Intel Core i7-7700T at 2039 (0.4% ahead).

The Verdict

The data points to a split decision based on workload. The AMD Ryzen 5 7520U is the clear choice for single-threaded tasks and older Cinebench benchmarks. Its Cinebench R15 single-core score of 168.8 is nearly double the Intel part’s 90, and it holds a 30.5% lead in Cinebench R23 single-core. It also wins Cinebench R15 multi-core by 30.1%. Anyone running legacy benchmark suites or lightly threaded applications should favor the AMD part.

The Intel Core i7-5775R takes the modern multi-core crown. Its Cinebench R23 multi-core score of 6360 beats AMD’s 5149 by 19%. Geekbench results also favor Intel, with a 5.8% multi-core lead and a 2.7% single-core lead. For users who rely on current rendering workloads or Geekbench-style tests, the Intel chip is the stronger option.

The average benchmark scores are nearly identical: 2046 for AMD versus 2031 for Intel. Both sit at the 45th percentile. The verdict is workload-dependent, not a clear overall winner. The AMD part excels in single-threaded and older multi-threaded tests, while the Intel part wins the newer Cinebench R23 multi-core and Geekbench tests. Neither CPU dominates the other across the full suite.

Where Each One Wins

The AMD Ryzen 5 7520U wins in scenarios that favor single-threaded performance or older benchmark suites. Its Cinebench R15 single-core score of 168.8 is 87.6% ahead of the Intel part, and its Cinebench R23 single-core score of 1171 is 30.5% ahead. It also wins Cinebench R15 multi-core by 30.1%, scoring 834 versus 641. This makes it the better choice for legacy applications, lightly threaded workloads, and any software that relies on high boost clocks. The AMD part’s higher boost clock of 4.30 GHz supports this advantage. Its 15 W TDP also indicates a power-efficient design, though no power consumption measurements are in the data.

The Intel Core i7-5775R wins in modern multi-threaded and Geekbench workloads. Its Cinebench R23 multi-core score of 6360 beats AMD’s 5149 by 19%. Geekbench multi-core is 3996 versus 3766, a 5.8% lead, and Geekbench single-core is 1218 versus 1185, a 2.7% lead. This makes it the stronger option for current rendering tasks, multi-threaded productivity, and Geekbench-style synthetic tests. The Intel part’s larger 6 MB L3 cache likely contributes to its multi-threaded advantage. Its base clock of 3.30 GHz is higher than AMD’s 2.80 GHz, which helps in sustained multi-core loads.

The overall split is three wins each. The AMD part dominates in single-threaded and older benchmarks. The Intel part wins the newer multi-threaded benchmark and both Geekbench tests. The average scores are nearly tied, so the choice depends entirely on which benchmark set matters more to the user. The AMD part is better for single-core and legacy workloads. The Intel part is better for modern multi-core and Geekbench tests.
