AMD Ryzen 5 5600F vs Intel Core 3 305 Comparison

Head-to-Head Benchmarks

The recorded data shows a clear split between these two processors, with the AMD Ryzen 5 5600F taking seven of the eleven shared benchmark tests while the Intel Core 3 305 claims four. The margins vary widely, from a near-tie in prime number generation to a dominant 83.7% lead in integer math for the AMD part.

Starting with the AMD’s strongest showing, the Ryzen 5 5600F scores 232,836 in data compression against the Intel’s 146,857, a 58.5% advantage. This is the largest gap in the entire head-to-head set. The integer math test tells a similar story: 59,339 versus 32,295, an 83.7% lead. Those two workloads reward the AMD’s higher sustained multi-threaded throughput and larger shared cache. The random string sorting test also goes to AMD, 23,422 versus 17,623, a 32.9% margin, which again points to a strong memory subsystem and thread-handling capability.

The encryption test shows a 25.6% win for AMD (13,839 versus 11,019), and the extended instructions benchmark gives AMD a 20.1% edge (16,266 versus 13,543). The multithread score, a broad measure of parallel performance, lands at 19,236 for AMD versus 15,439 for Intel, a 24.6% difference. Even the closest contest, find prime numbers, goes to AMD by a slim 4.3% (120 versus 115). These results collectively indicate that the Ryzen 5 5600F, with its 12 threads against Intel’s 6, consistently outpaces the Core 3 305 in any workload that scales with thread count or benefits from a large shared L3 cache.

The Intel Core 3 305, however, dominates where single-thread speed and specific math operations matter. The single-thread test shows Intel at 3,977 against AMD’s 2,872, a 27.8% advantage. This is the second-largest gap in the dataset, and it appears twice in the results (the singlethread test repeats the same figures). The floating point math test gives Intel a 42,284 score versus AMD’s 34,548, an 18.3% lead. The physics test, which often reflects a mix of single-thread and moderate parallel load, also favors Intel: 1,233 versus 1,043, a 15.4% edge. These wins show that Intel’s higher boost clock of 4.30 GHz, compared to AMD’s 4.00 GHz, translates into faster per-core execution in scenarios where the workload does not saturate all available threads.

The overall benchmark averages reinforce this division. The AMD Ryzen 5 5600F carries an average benchmark score of 36,945, placing it in the 85th percentile among all CPUs. The Intel Core 3 305 averages 18,302, sitting in the 72nd percentile. That difference of roughly double the average score is consistent with the multithread-heavy wins for AMD, but the percentile gap also reflects the fact that the Intel part is a mobile-focused chip with a much lower power envelope.

Where Each One Wins

The data points to a clear use-case split. The AMD Ryzen 5 5600F wins in data compression, encryption, extended instruction workloads, integer math, multithreaded tasks, random string sorting, and prime number generation. These are all workloads where having 12 threads instead of 6, plus a 32 MB shared L3 cache, provides a distinct advantage. For example, data compression often relies on multiple threads to process blocks in parallel, and the AMD’s 32 MB cache can hold more working data than Intel’s 6 MB shared L3. Integer math similarly scales with thread count, and the 83.7% margin suggests the AMD part is nearly twice as fast in that specific operation.

The Intel Core 3 305 wins in single-thread performance, floating point math, and the physics test. The single-thread win, with a 27.8% lead, is the most straightforward: the Intel chip boosts to 4.30 GHz, and with only 6 threads to manage, each core can draw more power and run closer to that ceiling for longer. The floating point win is more nuanced, as it does not always scale perfectly with threads; the Intel’s 42,284 score versus AMD’s 34,548 indicates that its per-core floating point throughput is higher, possibly due to a more modern instruction pipeline on the 3 nm node. The physics test, which often combines ray tracing or rigid body calculations with some parallelism, also favors Intel, suggesting that the workload’s single-thread component dominates the result.

For a user running heavily threaded productivity tasks, video encoding, or compilation, the AMD Ryzen 5 5600F is the clear choice based on the multithread, integer, and compression scores. For single-threaded applications, legacy software, or workloads that are heavily floating-point dependent, such as certain scientific simulations or audio processing, the Intel Core 3 305 shows a measurable edge. The physics win is notable for gaming, as many game engines have a primary physics thread that benefits from high single-thread clocks, but the overall gaming picture is mixed given that the AMD part has more threads for background tasks.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 5600F uses the Zen 3 architecture, codenamed Vermeer, built on a 7 nm process at TSMC. It has 6 cores and 12 threads, with a base clock of 3.00 GHz and a boost clock of 4.00 GHz. The thermal design power is 65 watts, and it fits the AMD Socket AM4. The cache layout is per-core L1 at 64 KB, per-core L2 at 512 KB, and a shared L3 at 32 MB. That 32 MB shared pool is a hallmark of the Zen 3 design, allowing all cores to access a large, low-latency cache for data that is frequently reused across threads. The chip also supports DDR4 memory in a dual-channel configuration, with a memory bandwidth of 51.2 GB/s, and it supports ECC memory. It offers PCIe Gen 4 with 20 lanes from the CPU, and it has no integrated graphics. The multiplier is unlocked, meaning overclocking is possible on supported motherboards.

The Intel Core 3 305 uses the Wildcat Lake codename, built on a 3 nm process at Intel’s own fabs. It has 6 cores but only 6 threads, so no hyperthreading or simultaneous multithreading. The base clock is notably low at 1.50 GHz, but the boost clock reaches 4.30 GHz, the highest in this comparison. The thermal design power is just 15 watts, reflecting its mobile market segment and BGA 1516 socket, which is soldered rather than socketed. The cache structure is reported as 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3, which is a much smaller L3 than the AMD part. Memory support includes DDR5 and LPDDR5X, but the memory bus is single-channel, which is unusual for a desktop-class chip; the memory bandwidth is 59.7 GB/s, slightly higher than the AMD’s 51.2 GB/s despite the single channel, due to higher-speed memory types. ECC memory is not supported. The Intel part has only 6 PCIe Gen 4 lanes from the CPU, and it includes integrated graphics: Intel Xe3 Graphics with 1 Xe core. The multiplier is locked, so no user overclocking.

The process node difference is substantial: 7 nm for AMD versus 3 nm for Intel. That explains why the Intel part can achieve a 4.30 GHz boost clock at only 15 watts TDP, while the AMD part needs 65 watts to reach 4.00 GHz. However, the AMD part compensates with a much larger cache and double the thread count. The single-channel memory bus on the Intel part is a notable limitation for memory-heavy workloads, as it halves the effective memory parallelism compared to the AMD’s dual-channel configuration, even though the raw bandwidth figure is higher due to DDR5/LPDDR5X support.

The Verdict

The data supports a straightforward verdict based on workload type. The AMD Ryzen 5 5600F wins seven of the eleven head-to-head benchmarks, with decisive margins in integer math (83.7%), data compression (58.5%), random string sorting (32.9%), encryption (25.6%), multithread (24.6%), and extended instructions (20.1%). Its average benchmark score of 36,945 places it in the 85th percentile, far above the Intel’s 18,302 average and 72nd percentile. For any user who cares about parallel throughput, large L3 cache, or memory bandwidth via dual-channel DDR4, the AMD part is the superior choice.

The Intel Core 3 305 wins the remaining four benchmarks, but its victories are concentrated in single-thread and floating point areas. The 27.8% single-thread lead and 18.3% floating point lead are significant for specific applications, but the overall average score is less than half of the AMD’s. The Intel part also carries a 15-watt TDP, making it far more power-efficient, which matters for mobile or fanless designs. Its integrated graphics, a feature the AMD part lacks entirely, could be a deciding factor for systems without a discrete GPU.

Given the data, the AMD Ryzen 5 5600F is the choice for desktop builds focused on multi-threaded productivity, content creation, or any workload that can use 12 threads. The Intel Core 3 305 is the choice for mobile platforms, single-threaded application performance, or systems where power consumption is critical and integrated graphics are required. The 65-watt TDP of the AMD part versus the 15-watt TDP of the Intel part is a stark difference that should not be ignored, but for raw performance across the measured benchmarks, the AMD part delivers more consistent wins.
