AMD Ryzen 5 3500X vs Intel Core i7-7700 Comparison

The AMD Ryzen 5 3500X and Intel Core i7-7700 present a generational clash, with the data showing a decisive sweep. Across the 19 head-to-head benchmark comparisons, the Ryzen 5 3500X wins every single test, registering a 19-0 victory. The average benchmark score for the AMD part is 12000, while the Intel i7-7700 trails at 11914, a difference of 0.7%. While the overall average scores are close, the individual workload results reveal where each chip's architecture flexes its muscles, and the gaps are often dramatic.

Head-to-Head Benchmarks

The most striking victories for the Ryzen 5 3500X come in heavily threaded and specialized workloads. In the PassMark find prime numbers test, the AMD chip scores 130 against Intel's 28, a staggering 364.3% advantage. This points to a fundamental throughput advantage in raw integer calculation. Similarly, the data encryption benchmark shows a 144.7% delta, with the Ryzen scoring 7276 versus 2974 for the i7-7700, indicating a major edge in cryptographic workloads. The PassMark physics test also shows a massive gap, with the Ryzen 5 3500X scoring 1234 compared to 588, a 109.9% lead.

The Cinebench suite reinforces this trend across the board. In Cinebench R23 multi-core, the Ryzen 5 3500X scores 11196, while the i7-7700 manages 7344, a 52.5% delta. This pattern is consistent across R15, R20, and R23, with multi-core deltas hovering around 52.4% to 52.5%. Single-core performance in Cinebench also strongly favors AMD, with a 52.9% delta in R15 (159 vs 104) and a 52.5% delta in R23 (1580 vs 1036). This is not just a multi-threaded story; the Zen 2 architecture delivers a substantial single-threaded advantage in this rendering workload.

Geekbench results show a more nuanced picture, though AMD still wins. In multi-core, the Ryzen 5 3500X scores 6331 versus 4640 for the i7-7700, a 36.4% lead. The single-core delta is much smaller at 12.4%, with scores of 1539 and 1369 respectively. This suggests that in more general-purpose integer and floating-point tasks, the per-core performance gap narrows considerably. The PassMark single-thread test confirms this, showing a minimal 2.5% delta, with the Ryzen 5 3500X scoring 2502 and the i7-7700 scoring 2442. The PassMark random string sorting test also shows a close race, with a 4.9% delta (16263 vs 15509), indicating that memory latency-sensitive, single-threaded operations are much closer.

Architecture Differences

The architectural divide between these two processors explains the benchmark results. The AMD Ryzen 5 3500X is built on the Zen 2 architecture (codename Matisse) using a 7 nm process from TSMC, featuring 3,800 million transistors on a 74 mm² die. In contrast, the Intel Core i7-7700 uses the Kaby Lake architecture on Intel's 14 nm process. This node advantage is a primary driver of the performance gap, allowing AMD to pack more compute into a smaller, more efficient space.

Core and thread counts differ significantly. The Ryzen 5 3500X offers 6 cores and 6 threads, while the i7-7700 provides 4 cores and 8 threads. While Intel relies on Hyper-Threading to reach 8 threads, AMD's 6 physical cores provide a raw throughput advantage that is visible in multi-threaded benchmarks. Cache hierarchies also differ substantially: the Ryzen 5 3500X has 512 KB of L2 cache per core and a large 32 MB shared L3 cache, whereas the i7-7700 has 256 KB of L2 per core and only 8 MB of shared L3. This 4x difference in L3 cache is likely a key factor in the massive deltas seen in data encryption and prime number tests.

Memory bandwidth is another differentiator. The AMD chip supports dual-channel DDR4 with a theoretical bandwidth of 51.2 GB/s, while the Intel part also supports dual-channel DDR4 but caps out at 38.4 GB/s. This 33% bandwidth advantage helps the Ryzen 5 3500X in memory-intensive workloads. Platform support also diverges: the Ryzen 5 3500X uses the AMD Socket AM4 and supports PCIe Gen 4 with 24 lanes, while the i7-7700 uses Intel Socket 1151 and is limited to PCIe Gen 3 with 16 lanes. The Ryzen 5 3500X also has an unlocked multiplier, whereas the i7-7700 is locked.

Where Each One Wins

The data is unambiguous: the AMD Ryzen 5 3500X wins in every single benchmark category. There is no workload in the FACT PACK where the Intel Core i7-7700 comes out ahead. This means the Ryzen 5 3500X is the superior choice for all tested scenarios, from heavily threaded rendering to lightly threaded single-core tasks. The largest wins for AMD are in specialized compute tasks like prime number finding (364.3% delta), data encryption (144.7%), and physics simulation (109.9%). These tasks clearly benefit from the combination of more physical cores, a larger cache, and higher memory bandwidth.

The Intel i7-7700 comes closest in single-threaded, low-complexity tasks. The PassMark single-thread test shows only a 2.5% delta, and the random string sorting test shows a 4.9% delta. These results suggest that for very basic, latency-bound operations, the older Kaby Lake architecture is nearly competitive. However, even in these cases, the Ryzen 5 3500X still wins. The i7-7700 has a higher boost clock at 4.20 GHz compared to 4.10 GHz on the AMD part, but this 0.1 GHz advantage is insufficient to overcome the architectural efficiency of Zen 2. The i7-7700 also includes integrated graphics (HD 630), which the Ryzen 5 3500X lacks, but this does not affect the CPU benchmark results.

The Verdict

The benchmark data is clear: the AMD Ryzen 5 3500X is the superior processor in every measured workload. With a 19-0 record in head-to-head tests, there is no scenario where the Intel Core i7-7700 offers better performance. The Ryzen 5 3500X delivers a 52.5% advantage in Cinebench R23 multi-core rendering, a 144.7% advantage in data encryption, and even a 2.5% advantage in single-threaded PassMark tests. The architecture differences, including the 7 nm process, 6 physical cores, larger caches, and higher memory bandwidth, all contribute to this comprehensive victory.

Anyone choosing between these two CPUs should select the AMD Ryzen 5 3500X. It offers better performance across all benchmark categories, from heavily threaded productivity to lightly threaded responsiveness. The Intel Core i7-7700, despite its higher boost clock and integrated graphics, cannot match the Zen 2 architecture's efficiency. The data suggests that even with fewer threads, the AMD chip's superior IPC and memory subsystem make it the definitive choice. The only scenario where the i7-7700 is competitive is in the narrow band of PassMark single-thread tests, where the delta is just 2.5%, but it still loses. For any user, the Ryzen 5 3500X is the clear winner based on the benchmark results.
