CPU Comparison

The Intel Core 5 320 and AMD Ryzen 5 3600XT are six-core processors that occupy different corners of the market, yet their average benchmark scores sit within 0.7% of each other. The Intel part, a mobile Wildcat Lake chip on a 3 nm process, trades heavily on single-thread efficiency and integrated graphics, while the AMD chip is a desktop Zen 2 part with twelve threads and a much larger cache. The data shows a clear split: the AMD Ryzen 5 3600XT dominates multi-threaded and throughput-oriented workloads, while the Intel Core 5 320 takes the crown in specific math and single-thread tasks.

Where Each One Wins

The benchmark results paint a decisive picture in favor of the AMD Ryzen 5 3600XT for most compute-heavy scenarios. Out of 17 head-to-head tests, the Ryzen wins 12, including all Cinebench multi-core runs, all PassMark throughput tests except one, and several single-core Cinebench iterations. This makes it the obvious choice for rendering, video encoding, compression, encryption, and any workload that scales with thread count or sustained memory bandwidth.

The Intel Core 5 320 wins 5 tests, but its victories are concentrated and significant. It dominates PassMark single-thread performance with a 47% lead, and it wins PassMark floating-point math by 40.8%. It also edges out the Ryzen in Cinebench R15 single-core by 23.2% and PassMark physics by 0.9%. This pattern suggests the Intel chip is better suited for lightly threaded applications, legacy single-threaded software, and workloads that rely heavily on floating-point arithmetic, such as certain scientific simulations or financial modeling.

In practical terms, the Ryzen 5 3600XT is the workhorse for productivity and content creation. The Intel Core 5 320 is the specialist for snappy response in single-threaded apps and for tasks that leverage its floating-point unit. The average benchmark scores reflect this near-parity: the Intel chip averages 18023 versus 17891 for the AMD part, a 0.7% difference that masks the vastly different performance profiles.

Architecture Differences

The two chips are built on fundamentally different foundations. The Intel Core 5 320 uses the Wildcat Lake codename and a 3 nm process node, fabricated by Intel itself. It is a mobile part with a 15 W TDP, soldered to an Intel BGA 1516 socket. Its six cores run with six threads, meaning no simultaneous multithreading. The base clock is 1.50 GHz with a boost of 4.60 GHz. Cache is arranged as 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. Memory support includes DDR5 and LPDDR5X over a single-channel bus, delivering 59.7 GB/s of bandwidth. The chip also features integrated Intel Xe3 Graphics with 2 Xe cores and PCIe Gen 4 with 6 CPU lanes.

The AMD Ryzen 5 3600XT belongs to the 3000 series, built on Zen 2 architecture with the codename Matisse 2. It uses a 7 nm process from TSMC, with 3,800 million transistors on a 74 mm² die. The desktop part has a 95 W TDP and fits into AMD Socket AM4. It provides six cores and twelve threads, with a base clock of 3.80 GHz and boost of 4.50 GHz. Cache is organized as 64 KB of L1 per core, 512 KB of L2 per core, and a larger 32 MB of shared L3. Memory support is DDR4 over a dual-channel bus, yielding 51.2 GB/s of bandwidth. There is no integrated graphics, and the multiplier is unlocked for overclocking.

These differences explain the benchmark outcomes. The AMD chip has twice the threads and over five times the L3 cache, which directly boosts multi-threaded and data-heavy workloads. The Intel chip compensates with a higher boost clock, a newer process node, and faster memory types, which helps in single-thread and floating-point tasks. The absence of integrated graphics on the AMD part is a notable distinction for anyone building a system without a discrete GPU.

Head-to-Head Benchmarks

The largest single win for the AMD Ryzen 5 3600XT comes in Cinebench R23 multi-core, where it scores 15776 against the Intel’s 6197, a 60.7% advantage. That gap is massive and reflects the thread count and cache advantage. In Cinebench R15 multi-core, the AMD part scores 1590 versus 1054, a 33.7% lead. The R20 multi-core test shows a 17.6% lead for AMD, with scores of 6625 against 5462.

The AMD chip also wins the single-core Cinebench tests, albeit by smaller margins. In R20 single-core, it scores 935 versus 771, a 17.5% lead. In R23 single-core, the margin narrows to 13.5%, with scores of 2227 against 1926. The only single-core Cinebench test the Intel wins is R15, where it scores 276 versus 224, a 23.2% lead.

In PassMark tests, the AMD Ryzen 5 3600XT takes data compression (230645 vs 148779, a 35.5% lead), data encryption (14608 vs 10984, 24.8% lead), extended instructions (14585 vs 13262, 9.1% lead), integer math (51416 vs 32323, 37.1% lead), multithread (18562 vs 15450, 16.8% lead), and random string sorting (24960 vs 18038, 27.7% lead). The find prime numbers test is nearly a tie, with AMD ahead by just 2.7% (113 vs 110).

The Intel Core 5 320’s wins are more dramatic in percentage terms. PassMark single-thread shows 4045 versus 2752, a 47% lead. PassMark floating-point math shows 42440 versus 30149, a 40.8% lead. PassMark physics is a near tie, with Intel ahead by 0.9% (1221 vs 1210). These wins are significant but cover fewer workloads, making the AMD chip the more versatile performer.

The Verdict

The data supports a clear recommendation for the AMD Ryzen 5 3600XT for anyone building a desktop that prioritizes multi-threaded productivity. It wins 12 of 17 head-to-head tests, with especially large margins in Cinebench R23 multi-core (60.7% ahead) and PassMark integer math (37.1% ahead). Its 12 threads and 32 MB of L3 cache make it the superior choice for rendering, encoding, compression, and encryption. The unlocked multiplier adds flexibility for enthusiasts, and the lower launch MSRP of $249 versus $340 for the Intel part is notable.

The Intel Core 5 320 is the better pick only if your workload is dominated by single-threaded tasks or floating-point math. Its 47% lead in PassMark single-thread and 40.8% lead in floating-point math are substantial. The 15 W TDP and integrated graphics make it a strong candidate for a compact, low-power system or a laptop where battery life and portability matter. However, its 6 MB of L3 cache and lack of multithreading hold it back in almost every throughput-heavy test.

For most users, the AMD Ryzen 5 3600XT offers the better overall performance profile. The Intel Core 5 320 is a niche product that excels in specific areas but cannot match the AMD chip’s versatility. If you need a fast single-threaded mobile processor, the Intel part works. If you need a desktop CPU that handles everything, the AMD part is the data-backed winner.
