AMD Ryzen 5 5500X3D vs Intel Core 5 320 Comparison

The AMD Ryzen 5 5500X3D and the Intel Core 5 320 occupy very different corners of the processor market, yet their benchmark results offer a clear comparison of what each design prioritizes. The AMD part is a desktop-focused 6-core processor built on a mature 7 nm process, while the Intel part is a mobile-oriented 6-core chip on a 3 nm node. The recorded data shows an 8 to 3 split in head-to-head wins, but the individual workloads tell a more nuanced story about threading, cache, and clock speed.

Head-to-Head Benchmarks

The most decisive victory for the AMD Ryzen 5 5500X3D comes in the physics test, where it scores 2282 against the Intel Core 5 320’s 1221. That is a 86.9% advantage, the largest margin in the entire comparison. This workload is heavily multi-threaded and cache-sensitive, and the AMD chip’s combination of 12 threads and 96 MB of shared L3 cache delivers a massive lead. A similar pattern emerges in integer math, where the AMD part scores 60033 versus 32323, a 85.7% difference. Integer operations often scale with core count and cache capacity, so the AMD processor’s dual-thread-per-core setup and large L3 pool provide a clear edge.

The data compression benchmark also favors the AMD Ryzen 5 5500X3D heavily. It records 230392 points against Intel’s 148779, a 54.9% win. Compression algorithms benefit from both high memory bandwidth and large caches, and the AMD chip’s 96 MB L3 cache appears to be the deciding factor. The find prime numbers test shows a 54.5% lead for AMD (170 vs 110), another workload that responds well to cache size and thread count. Random string sorting gives AMD a 31.3% advantage (23675 vs 18038), and the multithread score shows a 31.8% lead (20363 vs 15450). These results indicate that the AMD processor consistently wins in tasks that can use more than six threads or that benefit from a large shared cache.

Data encryption is another win for AMD, though by a smaller margin. The Ryzen 5 5500X3D scores 13967 against Intel’s 10984, a 27.2% difference. Extended instructions also go to AMD, with 15925 versus 13262, a 20.1% lead. These workloads rely on both raw integer throughput and efficient instruction handling, and the AMD chip’s older but well-proven Zen 3 architecture holds up well.

The Intel Core 5 320 takes the single-thread tests decisively. Its score of 4045 in passmark_single_thread beats AMD’s 2941, a 27.3% advantage. The same gap appears in the duplicate singlethread entry, also 4045 vs 2941. This is the clearest area of Intel superiority. The Core 5 320 has a boost clock of 4.60 GHz compared to AMD’s 4.00 GHz, and it operates on a newer 3 nm process, which allows higher frequencies per watt. The floating point math test is the other Intel win, with a score of 42440 versus AMD’s 34511, an 18.7% margin. Floating point throughput often tracks with vector unit efficiency and clock speed, so the Intel chip’s higher boost clock and newer design give it an edge here.

Overall, the AMD Ryzen 5 5500X3D wins eight of the eleven recorded benchmarks, with all of its victories coming in multi-threaded or cache-heavy workloads. The Intel Core 5 320 wins three tests, all of which favor high clock speeds and single-core execution.

Where Each One Wins

The AMD Ryzen 5 5500X3D is the stronger choice for workloads that scale across threads or that repeatedly access large datasets. Its 12 threads versus Intel’s 6 threads provide a natural advantage in rendering, scientific computing, and heavy multitasking. The 96 MB of shared L3 cache is the standout feature here; it is 16 times larger than the Intel chip’s 6 MB L3 cache, and the benchmark data reflects that in compression, prime number finding, and physics simulations. The multithread score of 20363 versus 15450 confirms that the AMD part is the better option for any application that can use more than six threads. Data compression and encryption also favor AMD, so file archiving and some security workloads will run faster on the Ryzen 5 5500X3D.

The Intel Core 5 320 wins where single-thread performance and clock speed matter most. Its 4.60 GHz boost clock is 0.60 GHz higher than AMD’s 4.00 GHz, and the newer 3 nm process contributes to better frequency scaling. The single-thread score of 4045 is a full 37.5% higher than AMD’s 2941, which makes the Intel chip the better fit for lightly threaded applications like many games, web browsing, and office tasks that rely on one or two cores. The floating point math win also suggests that the Intel part handles vector math and some scientific workloads more efficiently, though the margin is smaller. The Intel chip’s integrated Xe3 Graphics also gives it a capability that AMD lacks entirely in this comparison, though the benchmark data does not include graphics scores.

Architecture Differences

The two processors come from different design philosophies and different process nodes. The AMD Ryzen 5 5500X3D uses the Zen 3 architecture, codenamed Vermeer, built on a 7 nm process at TSMC. It has 6 cores and 12 threads, meaning each core can handle two threads simultaneously. The base clock is 3.00 GHz and the boost clock is 4.00 GHz. The cache layout is unusual: 64 KB of L1 per core, 512 KB of L2 per core, and a massive 96 MB of shared L3 cache. That L3 cache is the defining characteristic of the X3D variant, and it is what drives many of the multi-threaded benchmark wins. The processor consumes 105 watts of TDP and fits into AMD Socket AM4. It supports DDR4 memory in a dual-channel configuration with a memory bandwidth of 51.2 GB/s. ECC memory is supported, and the processor provides 20 PCIe Gen 4 lanes. The chip has no integrated graphics, so a discrete GPU is required.

The Intel Core 5 320 uses the Wildcat Lake codename and is built on a 3 nm process at Intel. It has 6 cores but only 6 threads, so there is no simultaneous multithreading. The base clock is 1.50 GHz, which is very low, but the boost clock reaches 4.60 GHz. The cache is much smaller: 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. This is a mobile processor designed for power efficiency, reflected in its 15 watt TDP. It uses Intel BGA 1516 socket, which means it is soldered to the motherboard and not upgradeable. Memory support includes DDR5 and LPDDR5X, but the memory bus is single-channel, which limits memory bandwidth to 59.7 GB/s despite the faster memory types. ECC memory is not supported. The processor provides only 6 PCIe Gen 4 lanes. A major difference is the integrated Intel Xe3 Graphics with 2 Xe cores, which makes the Intel chip a complete system-on-chip solution. The AMD part has no integrated graphics at all.

The process node difference is significant: 3 nm versus 7 nm. That allows Intel to pack more transistors per area and run at higher clocks with lower power, which explains the 4.60 GHz boost clock on a 15 watt TDP. The Intel chip’s base clock of 1.50 GHz is half of AMD’s 3.00 GHz, but in practice the boost clock matters more for burst workloads. The AMD part’s 105 watt TDP is seven times higher than Intel’s, which reflects its desktop design and the overhead of maintaining a large L3 cache.

The Verdict

The data points to a clear split based on workload type. The AMD Ryzen 5 5500X3D is the stronger processor for multi-threaded tasks, cache-heavy workloads, and applications that can use 12 threads. Its 96 MB of L3 cache and dual-thread-per-core design deliver decisive wins in physics, integer math, data compression, and multithreaded benchmarks. It also holds the higher average benchmark score of 37018, placing it in the 85th percentile of all CPUs. The Intel Core 5 320 has an average score of 18023 and sits in the 72nd percentile.

The Intel Core 5 320 is the better choice for single-thread performance and power efficiency. Its 27.3% lead in single-thread tests and 18.7% lead in floating point math make it suitable for lightly threaded applications and vector-heavy tasks. The 15 watt TDP is a fraction of AMD’s 105 watts, so the Intel chip is designed for battery-powered or thermally constrained systems. The integrated graphics is another practical advantage for systems without a discrete GPU.

For a desktop builder with access to AM4 motherboards and DDR4 memory, the AMD Ryzen 5 5500X3D offers superior multi-threaded performance and a massive cache. For a compact mobile system or a user prioritizing single-core speed and low power draw, the Intel Core 5 320 is the data-backed pick. The benchmark results do not show a single winner across all tests; they show two processors optimized for different environments, and the correct choice depends on whether the workload uses many threads or relies on high clock speeds.
