AMD Ryzen 5 7520C vs Intel Core i7-5950HQ Comparison

The AMD Ryzen 5 7520C and Intel Core i7-5950HQ are both quad-core, eight-thread mobile processors, yet they represent vastly different eras of design. The data shows a clean sweep in raw compute benchmarks for the newer AMD part, but the Intel chip’s legacy advantages in platform connectivity and graphics remain relevant. This analysis breaks down the benchmark results, architectural shifts, and the specific use cases where each processor retains a foothold.

Head-to-Head Benchmarks

The benchmark results are unambiguous: the AMD Ryzen 5 7520C wins every single test in the comparison suite. Across all six Cinebench iterations, the AMD part holds a consistent performance advantage, with deltas ranging from -11.3% to -11.5% (where a negative delta indicates the AMD chip is faster).

In multi-threaded workloads, the Ryzen 5 7520C posts scores of 741 in Cinebench R15, 3089 in R20, and 7355 in R23. The Intel Core i7-5950HQ trails with 656, 2736, and 6516 respectively. This translates to a lead of roughly 11.4-11.5% for AMD in these all-core tests. The margin is remarkably uniform, suggesting a consistent architectural efficiency advantage rather than a workload-specific quirk.

Single-threaded performance tells a similar story. The AMD part scores 104 in Cinebench R15 single-core, 435 in R20, and 1038 in R23. The Intel part manages 92, 386, and 920 respectively. The delta here is also approximately 11.3-11.5% in favor of AMD. This is notable because the Intel chip has a base clock of 2.90 GHz and a boost of 3.80 GHz, while the AMD chip has a lower base of 2.80 GHz but a much higher boost of 4.30 GHz. The data suggests the higher boost ceiling on the Ryzen 5 7520C effectively overcomes its lower base frequency in these bursty single-threaded tests.

Looking at the broader picture, the average benchmark score for the Ryzen 5 7520C is 2127, placing it in the 46th percentile of all CPUs. The Intel Core i7-5950HQ has an average score of 2158, which sits in the 47th percentile. Despite losing every head-to-head test, the Intel chip has a slightly higher average score. This is because the Intel data set includes Geekbench results (4601 multi-core, 1353 single-core), which are not present for the AMD part. These Geekbench scores boost Intel's average, illustrating how benchmark composition can affect aggregate rankings.

The nearest rivals for the Ryzen 5 7520C include the Intel Core i7-1160G7 (deltaPct 0.2%), Intel Atom C5125 (deltaPct 0.3%), AMD Ryzen 3 5300U (deltaPct -0.4%), and Intel Core i5-9400T (deltaPct -0.4%). For the Intel Core i7-5950HQ, the closest competitors are the Intel Core i5-10200H (deltaPct 0.2%), Intel Core i5-7640X (deltaPct -0.4%), AMD Ryzen 3 3300X (deltaPct 0.5%), and Intel Core i5-1145G7E (deltaPct -0.7%). These figures confirm that both chips are closely matched with a broad swath of mid-range processors from their respective eras.

Architecture Differences

The two processors are built on fundamentally different foundations. The Intel Core i7-5950HQ uses the Broadwell-H architecture, manufactured on Intel’s 14 nm process with a die size of 182 mm². The AMD Ryzen 5 7520C is based on the Zen 2 architecture, specifically the Mendocino codename, and is fabricated by TSMC on a 6 nm process with a die size of 100 mm². This process advantage is a primary driver behind the AMD chip’s ability to deliver higher performance while consuming significantly less power.

The cache hierarchies differ substantially. Both chips have 64 KB of L1 cache per core. However, the Intel part has 256 KB of L2 per core, while the AMD part doubles this to 512 KB per core. The shared L3 cache is larger on the Intel chip: 6 MB versus 4 MB. This suggests Intel was relying on a larger last-level cache to mitigate its older process node, while AMD’s design leans more on the per-core L2 and the efficiency of Zen 2.

Memory support is another major divergence. The Intel Core i7-5950HQ uses dual-channel DDR3 with a peak bandwidth of 29.9 GB/s. The AMD Ryzen 5 7520C uses dual-channel LPDDR5 with a much higher bandwidth of 88.0 GB/s. This nearly threefold increase in memory bandwidth is crucial for integrated graphics performance and memory-intensive applications. Neither chip supports ECC memory.

The integrated graphics solutions are also from different generations. The Intel chip features Iris Pro Graphics 6200, which was a high-end iGPU for its time. The AMD chip features Radeon 610M, a modern entry-level solution. While the benchmark data does not include graphics tests, the memory bandwidth figures suggest the AMD platform has a theoretical advantage for GPU tasks.

Platform connectivity shows a clear generational gap. The Intel Core i7-5950HQ offers PCIe Gen 3 with 16 lanes (CPU only), while the AMD Ryzen 5 7520C offers PCIe Gen 3 with only 4 lanes (CPU only). This is a critical distinction for users who plan to connect discrete GPUs or multiple NVMe drives. The Intel chip provides four times the PCIe lanes for expansion. The AMD chip is clearly designed for a more integrated, low-power laptop environment where expansion is minimal.

Power consumption is the starkest difference. The Intel part has a TDP of 47 W, while the AMD part has a TDP of just 15 W. This 32 W gap means the AMD chip generates significantly less heat and requires less cooling, making it suitable for thinner, fanless or low-noise designs. The Intel chip, with its higher TDP, belongs to a class of performance-oriented mobile processors from the mid-2010s.

Where Each One Wins

The AMD Ryzen 5 7520C is the clear winner in raw CPU compute. All six Cinebench tests point to AMD. This makes the Ryzen 5 7520C the better choice for CPU-bound productivity tasks like video encoding, 3D rendering, and software compilation. The 11.4% lead in multi-core R23 (7355 vs 6516) is significant for these workloads. The higher boost clock of 4.30 GHz also gives it an edge in single-threaded responsiveness, which matters for everyday tasks like web browsing and office applications.

The Intel Core i7-5950HQ wins on platform capability. The 16 PCIe Gen 3 lanes are a massive advantage over the 4 lanes on the AMD part. This makes the Intel chip the only viable option in this comparison for a system that requires a discrete graphics card or multiple high-speed storage devices. The larger 6 MB L3 cache and support for DDR3 are less relevant to modern users, but the PCIe bandwidth is a functional differentiator. Intel’s Iris Pro Graphics 6200 is also a notable asset, though the lack of comparative graphics benchmarks prevents a definitive performance claim.

The AMD Ryzen 5 7520C wins decisively on efficiency. Its 15 W TDP, compared to Intel’s 47 W, means it can sustain performance in thermally constrained chassis. The data shows it does so while being faster in every CPU test. The 6 nm process node and 100 mm² die size underscore its modern, power-optimized design. For any user prioritizing battery life and low heat output, the AMD part is the logical choice.

The Verdict

The data is clear: the AMD Ryzen 5 7520C is the superior CPU in every measurable compute benchmark. It is faster in all six Cinebench tests, with margins of about 11.4%. It achieves this while having a TDP of just 15 W compared to Intel’s 47 W. For any workload that relies on the CPU cores, the AMD part is the one to pick.

The Intel Core i7-5950HQ’s only redeeming factors are its platform features. The 16 PCIe Gen 3 lanes are a decisive advantage for a system builder who needs to install a discrete GPU or use multiple expansion cards. The Intel chip is the only option here for that kind of expandable mobile workstation.

However, the AMD Ryzen 5 7520C’s combination of higher performance and dramatically lower power consumption makes it the better choice for the vast majority of modern laptop use cases. The Intel chip is an end-of-life product from 2015, while the AMD chip is an active product from 2023. The benchmark data reflects this generational gap. The verdict is straightforward: choose the AMD Ryzen 5 7520C for its performance and efficiency, unless the specific need for 16 PCIe lanes forces a choice of the older Intel platform.
