AMD Ryzen 3 3300X vs Intel Xeon D-1548 Comparison

Head-to-Head Benchmarks

The recorded head-to-head data covers two Cinebench R15 workloads, and in both cases the AMD Ryzen 3 3300X posts the higher score. The most lopsided result is in the single-core test, where the Ryzen 3 3300X scores 195 against the Xeon D-1548's 109, a delta of 44.1 percent. That is a massive gap for a single-threaded workload, and it reflects the fundamental difference in clock behavior between the two parts: the AMD chip boosts to 4.30 GHz while the Intel part tops out at 2.60 GHz.

The multicore result is closer but still favors AMD. The Ryzen 3 3300X scores 1071 in Cinebench R15 multicore, while the Xeon D-1548 scores 777, a delta of 27.5 percent. This is notable because the Intel processor has twice the core count (8 cores versus 4) and twice the thread count (16 threads versus 8). Despite having half the physical resources, the Ryzen 3 3300X wins by over a quarter, which indicates that per-core throughput and higher clocks overcome the core deficit in this particular workload.

Looking beyond the direct head-to-head, the broader benchmark database shows a similar pattern. The Xeon D-1548 has a Cinebench R20 multicore score of 3239 and a single-core score of 457, while its R23 results are 7713 multicore and 1089 single-core. The Ryzen 3 3300X does not have R20 or R23 entries in the database, so direct comparisons in those newer workloads are not possible from the recorded data. However, the Geekbench results for the AMD part (5772 multicore, 1555 single-core) suggest that its single-thread advantage carries into other test suites.

The average benchmark scores place the two chips close together in the overall standings. The Xeon D-1548 averages 2231 across its recorded tests, while the Ryzen 3 3300X averages 2148. The Intel part sits at the 47th percentile of all CPUs, and the AMD part also sits at the 47th percentile. So while the direct head-to-head shows a clear AMD victory in both shared tests, the aggregate picture is nearly identical. The Xeon D-1548's nearest rivals include the Intel Xeon E5-4648 v3 (average score 2227, delta 0.2 percent) and the Intel Xeon D-1715TER (average score 2238, delta 0.3 percent behind). The Ryzen 3 3300X's nearest rivals include the Intel Core i5-10200H (average score 2154, delta 0.3 percent behind) and the Intel Core i7-5950HQ (average score 2158, delta 0.4 percent behind). Neither chip has a decisive overall edge in the database's average scoring.

The Cinebench R15 data is the only direct comparison available, and it is unambiguous. The Ryzen 3 3300X wins both tests, with a 27.5 percent margin in multicore and a 44.1 percent margin in single-core. That single-core delta is among the largest recorded in the database for comparable processors, and it is the single clearest differentiator between these two SKUs.

The Verdict

The data points to a straightforward conclusion for anyone choosing between these two processors. For workloads that rely on single-threaded performance, the AMD Ryzen 3 3300X is the clear choice, as it outperforms the Intel Xeon D-1548 by 44.1 percent in Cinebench R15 single-core. Even in multicore, where the Intel chip has twice as many cores and threads, the Ryzen 3 3300X leads by 27.5 percent. That means the AMD part is faster in every shared benchmark test in the database.

However, the verdict is not purely about raw speed. The Xeon D-1548 targets the server and workstation segment, while the Ryzen 3 3300X is a desktop part. The Intel chip supports ECC memory, the AMD chip does not. The Xeon D-1548 uses a BGA 1667 socket, meaning it is soldered to the board, while the Ryzen 3 3300X uses Socket AM4 and has an unlocked multiplier for overclocking. The Xeon D-1548 also carries a launch MSRP of $555, while the Ryzen 3 3300X carries a launch MSRP of $120.

From the recorded data alone, the Ryzen 3 3300X wins on performance in both shared tests and offers a lower launch MSRP. The Xeon D-1548 wins on platform attributes: ECC support, a server-grade socket, and a higher core count. The database shows both chips at the 47th percentile of all CPUs, so neither is an outlier in overall performance. The choice depends on whether the workload favors the AMD part's clock speed or the Intel part's server features.

Where Each One Wins

The AMD Ryzen 3 3300X wins in every benchmark where the two are directly compared. In Cinebench R15 single-core, its 195 versus 109 gives it a 44.1 percent lead. In Cinebench R15 multicore, its 1071 versus 777 gives it a 27.5 percent lead. This means for any application that is primarily limited by single-thread speed, such as older games or lightly threaded productivity tools, the Ryzen 3 3300X is the stronger option. Its 4.30 GHz boost clock versus the Xeon's 2.60 GHz is the obvious driver of this advantage.

The Ryzen 3 3300X also benefits from a newer architecture and process node. It uses Zen 2 on a 7 nm process from TSMC, while the Xeon D-1548 uses Broadwell on Intel's 14 nm process. The AMD chip has a smaller die (74 mm² versus 246 mm²) but more transistors (3,800 million versus 3,200 million), which reflects the denser 7 nm manufacturing. It also supports PCIe Gen 4 with 16 lanes, while the Xeon D-1548 supports PCIe Gen 3 with 24 lanes. For desktop users with modern GPUs or NVMe drives, the PCIe 4 support is a tangible benefit.

The Intel Xeon D-1548 wins in areas that are not captured by the Cinebench scores. It has 8 cores and 16 threads, double the Ryzen 3 3300X's 4 cores and 8 threads. In a hypothetical workload that scales perfectly with core count, the Xeon would have a theoretical advantage, but the recorded Cinebench R15 multicore result shows that advantage is not realized in that test. The Xeon also supports ECC memory, which is critical for servers and workstations that need error correction. Its memory support includes both DDR3 and DDR4, whereas the Ryzen 3 3300X supports only DDR4. The Xeon's memory bandwidth is not listed in the database, but the Ryzen 3 3300X has a recorded memory bandwidth of 51.2 GB/s.

The Xeon D-1548 has a lower TDP at 45 watts versus 65 watts for the Ryzen 3 3300X. That makes the Intel part more power-efficient on paper, which matters in dense server deployments. The Xeon also has a larger L3 cache allocation per core (1.5 MB per core), while the Ryzen 3 3300X has a shared 16 MB L3 cache. The Ryzen's cache is larger in total, but the Xeon's per-core allocation is higher.

Architecture Differences

The two processors come from different eras and design philosophies. The Intel Xeon D-1548 is based on the Broadwell architecture, specifically the Broadwell-DE variant for Xeon D, and was released in late 2015. It is built on Intel's 14 nm process at Intel's own foundry, with 3,200 million transistors on a 246 mm² die. The AMD Ryzen 3 3300X is based on Zen 2 (Matisse) and was released in early 2020. It is built on TSMC's 7 nm process, with 3,800 million transistors on a much smaller 74 mm² die. The smaller die with more transistors is a direct result of the denser 7 nm node.

The core configurations differ sharply. The Xeon D-1548 has 8 cores and 16 threads, with a base clock of 2.00 GHz and a boost clock of 2.60 GHz. The Ryzen 3 3300X has 4 cores and 8 threads, with a base clock of 3.80 GHz and a boost clock of 4.30 GHz. The AMD chip runs at nearly double the clock speed in both cases, which explains its single-core dominance.

Cache layouts also differ. The Xeon D-1548 has 64 KB of L1 per core, 256 KB of L2 per core, and 1.5 MB of L3 per core. The Ryzen 3 3300X has 64 KB of L1 per core, 512 KB of L2 per core, and a shared 16 MB L3 cache. The Ryzen's L2 is double per core, and its total L3 is larger at 16 MB shared versus the Xeon's per-core allocation. The Xeon's L3 is not listed as a total, so a direct comparison of total L3 is not possible from the database.

Memory support also separates the two. The Xeon D-1548 supports both DDR3 and DDR4, with a dual-channel memory bus, and has ECC capability. The Ryzen 3 3300X supports only DDR4, also with a dual-channel bus, and has a recorded memory bandwidth of 51.2 GB/s. The Xeon's memory bandwidth is not listed. The Xeon does not support ECC on the AMD side, which is a notable feature gap for server use.

PCIe connectivity differs by generation and lane count. The Xeon D-1548 provides PCIe Gen 3 with 24 lanes (CPU only), while the Ryzen 3 3300X provides PCIe Gen 4 with 16 lanes (CPU only). The newer PCIe 4 standard offers double the bandwidth per lane, so the AMD part's 16 lanes may outperform the Intel part's 24 Gen 3 lanes in bandwidth-sensitive applications.

The sockets are incompatible. The Xeon D-1548 uses Intel BGA 1667, a soldered embedded-style socket, while the Ryzen 3 3300X uses AMD Socket AM4, a standard desktop socket. The Xeon is not multiplier-unlocked, while the Ryzen 3 3300X has an unlocked multiplier for overclocking. The Xeon's market segment is server and workstation, while the Ryzen's is desktop. Both are listed as active in production status.

The TDP figures are 45 watts for the Xeon D-1548 and 65 watts for the Ryzen 3 3300X. The Xeon's lower TDP aligns with its server role, where power density and cooling are more constrained. The Ryzen's higher TDP reflects its higher clock speeds and desktop orientation. Neither chip has integrated graphics, so both require a discrete GPU.
