AMD Ryzen 3 4300G vs Intel Xeon 6315P Comparison

The Intel Xeon 6315P and AMD Ryzen 3 4300G are both quad-core processors, but they target opposite ends of the computing spectrum. The data is remarkably one-sided in traditional CPU benchmarks, with the Xeon 6315P winning 13 of 17 head-to-head tests, yet the Ryzen 3 4300G counters with decisive victories in specific workloads that reveal a distinct architectural philosophy. The Xeon 6315P is the clear performance leader in most metrics, but the Ryzen 3 4300G has a narrow, specialized edge that makes it the better choice for certain tasks.

Head-to-Head Benchmarks

The most striking pattern is the Xeon 6315P's near-sweep of the Cinebench suite. Across all six Cinebench iterations (R15, R20, and R23, both single-core and multi-core), the Intel part wins with a remarkably consistent margin of roughly 20.8%. For instance, in Cinebench R23 multi-core, the Xeon scores 10134 against the Ryzen's 8387, a 20.8% advantage. Single-core performance tells the same story: 1430 vs 1184 in R23 single-core, also a 20.8% gap. This consistency suggests a fundamental clock-speed and IPC advantage rather than workload-specific optimization.

The PassMark suite reinforces this dominance in several areas. The Xeon 6315P's single-thread score of 3795 crushes the Ryzen's 2425, a 56.5% lead. Floating-point math is another blowout: 33496 vs 17577, a 90.6% advantage for Intel. The physics test shows the largest gap outside of prime numbers, with the Xeon scoring 1156 against the Ryzen's 454, a 154.6% differential. Extended instructions also favor Intel, 10539 vs 9148, a 15.2% win. The find-prime-numbers test is an outlier in magnitude: the Xeon scores 150 versus the Ryzen's 20, a 650% difference that highlights a massive disparity in this specific algorithmic workload.

However, the Ryzen 3 4300G wins four tests, and these are not trivial victories. Data compression is a clear win for AMD: 137681 vs 118313, a 14.1% margin. Data encryption is even more decisive, with the Ryzen scoring 8176 against the Xeon's 5470, a 33.1% lead. Integer math also goes to AMD, 29737 vs 27046, a 9% advantage. The closest contest is random string sorting, where the Ryzen edges out the Xeon by a negligible 0.1% (14503 vs 14487). The overall multi-thread PassMark score still favors Intel, 11923 vs 9849, a 21.1% win, showing that the Xeon's single-thread and floating-point strengths outweigh the Ryzen's integer and encryption advantages in aggregate.

Where Each One Wins

The Xeon 6315P wins in any workload that relies on raw clock speed, floating-point math, or single-threaded performance. Its 56.5% single-thread lead over the Ryzen makes it the better choice for lightly-threaded applications, legacy software, and tasks like spreadsheet calculations or web browsing where one core dominates. The 90.6% advantage in floating-point math suggests a strong fit for scientific simulations, 3D rendering, or any numerical analysis that uses FPU-heavy code. The physics test result, a 154.6% lead, points to particular strength in physics-based simulations or certain engineering applications. The 650% prime-number advantage indicates the Xeon is far superior for cryptographic key generation or primality testing, though this is a niche use case.

The Ryzen 3 4300G wins where the workload involves data compression, encryption, or integer-heavy logic. Its 33.1% encryption advantage makes it the better option for VPN servers, disk encryption, or secure communications processing. The 14.1% data compression win suggests it excels in file archiving, database compression, or network packet processing. The 9% integer math lead means the Ryzen is better suited for general business logic, financial calculations, or any application that processes large amounts of whole numbers rather than decimals. The near-tie in random string sorting (0.1% apart) indicates both processors handle sorting tasks equivalently, so neither has a meaningful edge there.

The Ryzen's integrated Radeon Vega 6 graphics gives it a capability the Xeon completely lacks, as the Intel part has no integrated graphics. This means the Ryzen can power a display without a discrete GPU, making it viable for budget desktops or office PCs, while the Xeon requires a separate graphics card.

Specification Differences

The core counts are identical at 4 cores, but the Ryzen 3 4300G has 8 threads versus the Xeon's 4, meaning the Ryzen supports simultaneous multithreading while the Xeon does not. The clock speeds differ significantly: the Xeon has a 2.80 GHz base and 4.70 GHz boost, while the Ryzen has a 3.80 GHz base and 4.00 GHz boost. The Xeon's boost is 0.70 GHz higher, but its base is 1.00 GHz lower. Thermal design power differs, with the Xeon rated at 55W and the Ryzen at 65W. The Xeon uses Intel Socket 1700, while the Ryzen uses AMD Socket AM4.

Cache configurations are notably different. The Xeon has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 12 MB of shared L3 cache. The Ryzen has 64 KB L1 per core, 512 KB L2 per core, and only 4 MB of shared L3. The Xeon's 12 MB L3 is three times larger than the Ryzen's 4 MB. Memory support also diverges: the Xeon supports both DDR4 and DDR5 in dual-channel mode, while the Ryzen is limited to DDR4. The Ryzen has a stated memory bandwidth of 51.2 GB/s, while the Xeon's bandwidth is not specified in the data. ECC memory is supported by the Xeon but not the Ryzen.

The Xeon is a server/workstation part with a launch MSRP of $213, while the Ryzen is a desktop part with no listed MSRP. The Ryzen has an unlocked multiplier; the Xeon does not.

Architecture Differences

The Xeon 6315P is built on Intel's Raptor Lake architecture, specifically the Raptor Lake-R refresh, and is part of the Xeon 6 generation. It uses a 10 nm process node manufactured by Intel, with a die size of 163 mm². The Ryzen 3 4300G uses AMD's Zen 2 architecture under the Renoir codename, part of the 4000 series. It is built on a 7 nm process from TSMC, with a die size of 156 mm² and 9,800 million transistors. The process node difference (10 nm vs 7 nm) and foundry difference (Intel vs TSMC) are fundamental architectural divergences.

The Xeon's 12 MB shared L3 cache versus the Ryzen's 4 MB is the most significant cache difference, likely contributing to the Xeon's advantages in floating-point and physics tests. The Xeon's larger per-core L2 cache (1.25 MB vs 512 KB) also indicates a different cache hierarchy design. The Ryzen's 8 threads versus the Xeon's 4 threads means the Ryzen can handle more concurrent threads, yet the Xeon still wins multi-core benchmarks by about 21%, suggesting the Xeon's per-core efficiency and higher boost clock outweigh the Ryzen's thread-count advantage. The Xeon's support for both DDR4 and DDR5 memory gives it future-proofing potential, while the Ryzen is locked to DDR4. The Xeon's PCIe Gen 5 support is two generations ahead of the Ryzen's PCIe Gen 3. The Xeon's ECC memory support and server/workstation market segment highlight its enterprise orientation, while the Ryzen's integrated Radeon Vega 6 graphics and unlocked multiplier position it as a consumer desktop part.

The Verdict

The data is unambiguous: the Intel Xeon 6315P is the faster processor in the vast majority of tests. It wins 13 of 17 benchmarks, including all six Cinebench tests, all multi-thread PassMark tests, and every single-thread test. Its 20.8% lead across the Cinebench suite and 56.5% single-thread advantage make it the clear choice for anyone prioritizing raw CPU performance, floating-point math, or single-core speed. The Xeon's 650% win in prime-number finding and 154.6% win in physics further cement its status as the superior compute engine. The Xeon also offers ECC memory support and PCIe Gen 5, features that matter for server and workstation reliability.

However, the AMD Ryzen 3 4300G is not without its reasons to exist. It wins data encryption by 33.1% and data compression by 14.1%, making it the better option for encryption-heavy workloads or compression tasks. Its 9% integer math advantage suggests it handles general business logic more efficiently. The Ryzen's integrated Radeon Vega 6 graphics means it can function without a discrete GPU, which is a capability the Xeon entirely lacks. The Ryzen also has an unlocked multiplier, allowing for overclocking, and its 51.2 GB/s memory bandwidth is explicitly documented. For a desktop user who needs a complete system without a separate graphics card, or for workloads dominated by encryption and compression, the Ryzen is the practical pick.

For anyone building a server, workstation, or a system where maximum CPU throughput is the priority, the Intel Xeon 6315P is the decisive winner. Its benchmark dominance across nearly every category, combined with ECC memory support and PCIe Gen 5, makes it the superior choice. The Ryzen 3 4300G should be selected only when its specific strengths — encryption, compression, integer math, or integrated graphics — align with the workload, or when the lower power draw of a 65W TDP with an integrated GPU is preferable. The average benchmark scores are nearly identical (14574 vs 14503, a 0.5% difference), but that overall parity masks a very different performance profile. Choose the Xeon for raw power, choose the Ryzen for its specialized wins and integrated graphics.
