AMD Ryzen 5 5500 vs Intel Core i5-11600K Comparison

The Intel Core i5-11600K and AMD Ryzen 5 5500 are both six-core, twelve-thread desktop processors, but they represent fundamentally different design philosophies. The data shows a clear pattern: the Intel part dominates synthetic 3DMark and Geekbench testing, while the AMD chip fights back in specific PassMark workloads. With the Intel winning 22 of 25 head-to-head benchmarks, the overall scoreboard is lopsided, but the margins tell a more nuanced story than the win count suggests.

Head-to-Head Benchmarks

The 3DMark suite is where the Intel Core i5-11600K delivers its most decisive victories. In the 16-thread test, Intel scores 6247 against AMD’s 5386, a 16% advantage. The margin shrinks slightly in the 8-thread test (5268 vs 4593, a 14.7% lead), but the single-thread result shows the same story: 967 versus 836, a 15.7% gap. These are not marginal differences; they represent a substantial performance tier separation in threaded simulation workloads.

Geekbench follows the same trajectory. The multicore score favors Intel at 9238 versus 7976, a 15.8% margin, while the single-core result shows 1973 against 1730, a 14% lead. For applications that rely on bursty single-threaded performance, this is a meaningful gap. The Ryzen 5 5500’s lower base and boost clocks (3.60 GHz and 4.20 GHz versus 3.90 GHz and 4.90 GHz) likely explain this consistent deficit.

The Cinebench tests tell a completely different story. Here, the two processors are nearly inseparable. In Cinebench R23 multicore, Intel scores 16552 and AMD scores 16429, a razor-thin 0.7% difference. The R20 multicore result is similarly tight: 6951 versus 6900, again a 0.7% gap. Even the R15 single-core test shows only a 0.9% difference (235 vs 233). This suggests that in pure rendering workloads, the architectural efficiency of AMD’s Zen 3 nearly neutralizes Intel’s clock speed advantage.

The PassMark suite produces the only AMD victories. Data encryption is the standout: AMD scores 14851 against Intel’s 12212, a massive 17.8% win. Data compression also goes to AMD (245533 vs 242740, a 1.1% margin), and integer math follows with 65001 versus 64664, a 0.5% edge. These wins indicate that the Ryzen 5 5500 has specific strengths in cryptography and integer-heavy tasks. Intel’s PassMark wins are more modest: floating-point math (38269 vs 36815, a 3.9% lead), physics (944 vs 896, a 5.4% edge), and random string sorting (27870 vs 24757, a 12.6% margin). The single-thread PassMark result favors Intel by 9.4% (3344 vs 3058).

Architecture Differences

The Intel Core i5-11600K is built on Rocket Lake, a 14 nm process from Intel’s own foundry. The die size is 276 mm². In contrast, the AMD Ryzen 5 5500 uses Zen 3 architecture on a 7 nm process from TSMC, with a smaller 180 mm² die and 10,700 million transistors. This process node advantage is a key differentiator, allowing AMD to pack more efficiency into a smaller area.

Cache layouts differ significantly. Intel uses 80 KB of L1 cache per core and 256 KB of L2 per core, with 12 MB of shared L3 cache. AMD counters with 64 KB of L1 per core, 512 KB of L2 per core, and a larger 16 MB of L3 cache. The larger L3 on the Ryzen part likely contributes to its strong performance in compression and encryption workloads, where larger working sets can stay resident in cache.

The platform requirements diverge sharply. Intel uses Socket 1200, while AMD uses Socket AM4. Both support dual-channel DDR4 memory with identical 51.2 GB/s bandwidth, and neither supports ECC memory. However, PCIe connectivity is a major split: Intel offers Gen 4 with 20 lanes from the CPU, while AMD is limited to Gen 3. This means the Intel platform can support faster NVMe SSDs and newer GPUs at full bandwidth, assuming the motherboard supports it.

The integrated graphics situation is also stark. Intel includes UHD Graphics 750, while AMD ships no integrated GPU at all. This makes the Ryzen 5 5500 a non-starter for builds without a discrete graphics card. Intel’s TDP is 125 W versus AMD’s 65 W, a significant power envelope difference that affects cooling requirements and electricity costs. Production status reflects their ages: Intel is end-of-life, while AMD is still active. The release dates are roughly a year apart (March 2021 for Intel, April 2022 for AMD).

Where Each One Wins

The Intel Core i5-11600K wins in scenarios that stress raw multi-threaded throughput with high clock speeds. The 3DMark 16-thread and max-thread results, showing 16% and 15.9% leads respectively, indicate this CPU is better suited for physics simulations and complex 3D rendering tasks that scale with thread count. The Geekbench multicore advantage of 15.8% reinforces this pattern. For users running CPU-bound gaming benchmarks or content creation applications that utilize many threads, Intel is the stronger choice.

The single-thread performance gap is equally important. With a 15.7% lead in 3DMark single-thread, a 14% lead in Geekbench single-core, and a 9.4% lead in PassMark single-thread, the Intel chip is faster for everyday responsiveness and lightly-threaded applications. This includes older games, spreadsheet operations, and general desktop use where single-core speed dominates.

The AMD Ryzen 5 5500 has a narrower but real set of wins. PassMark data encryption shows a 17.8% advantage, making it the clear pick for cryptographic workloads, VPN servers, or disk encryption scenarios. Data compression also favors AMD by a small margin, which matters for file archiving and database operations. Integer math performance is slightly better, suggesting an edge in certain financial or scientific computations. The Ryzen also wins on platform efficiency: at 65 W TDP versus 125 W, it requires less cooling and draws less power, which can be decisive for small form factor builds or low-noise systems.

A: Intel offers PCIe Gen 4 with 20 CPU lanes, while AMD is limited to PCIe Gen 3. This affects the maximum bandwidth available for modern GPUs and NVMe drives.

Q: What are the cache differences?

A: Intel has 80 KB L1 and 256 KB L2 per core with 12 MB shared L3. AMD has 64 KB L1 and 512 KB L2 per core with 16 MB shared L3. AMD’s larger L3 cache likely contributes to its compression and encryption wins.

The Verdict

The data points to the Intel Core i5-11600K as the more capable processor for general and threaded performance. It wins 22 of 25 benchmarks, with particularly strong showings in 3DMark and Geekbench where it holds double-digit percentage leads. If the workload involves 3D rendering, physics simulation, or any task that benefits from high clock speeds across multiple threads, Intel is the clear choice. The integrated UHD Graphics 750 also provides a fallback display output that AMD lacks.

However, the Ryzen 5 5500 is not without merit. Its encryption performance is exceptional, beating Intel by 17.8%, and its compression and integer math wins show it can handle specific server or workstation tasks more efficiently. The 65 W TDP makes it a far more power-efficient option, which translates to lower cooling requirements and quieter operation. For builders prioritizing power draw or building in compact cases, the Ryzen part has a genuine appeal.

The choice ultimately depends on the workload. For a gaming or content creation rig where single-thread speed and 3D performance dominate, the Intel Core i5-11600K is the better pick. For a system dedicated to encryption, compression, or integer-heavy computation, the AMD Ryzen 5 5500 offers competitive or superior performance at less than half the power consumption. The Intel chip is end-of-life while AMD remains active, which matters for long-term availability. Neither processor is a bad choice, but the benchmark data gives the edge to Intel for most users.
