AMD Ryzen 3 7320C vs Intel Xeon 6315P Comparison

The Intel Xeon 6315P and AMD Ryzen 3 7320C are both 4-core processors, but they target entirely different segments of the market. The Xeon is a server/workstation part on Intel Socket 1700 with a 55 W TDP, while the Ryzen is a 15 W mobile chip on AMD Socket FT6. Benchmark data shows the Xeon winning 14 of 17 head-to-head tests, yet the Ryzen claims three notable PassMark victories, making the choice between them heavily dependent on workload and platform requirements.

FAQ

Q: Which processor has the higher single-thread performance?

A: The Intel Xeon 6315P is decisively ahead in single-core tests. In Cinebench R23 single-core, it scores 1430 versus the AMD Ryzen 3 7320C's 991, a 44.3% advantage. PassMark single-thread also favors Intel at 3795 versus 2439, a 55.6% lead.

Q: Does the AMD Ryzen 3 7320C ever win any benchmarks?

A: Yes, it wins three PassMark tests: data compression (144465 vs 118313, an 18.1% lead), integer math (32247 vs 27046, a 16.1% lead), and random string sorting (16973 vs 14487, a 14.6% lead). These are all memory or integer-heavy workloads.

Q: How do the core and thread counts compare?

A: Both have 4 physical cores, but the AMD Ryzen 3 7320C supports 8 threads via SMT, while the Intel Xeon 6315P has 4 threads with no multithreading. Despite this, the Xeon wins all multi-core Cinebench tests by roughly 44%.

Q: What is the difference in memory support?

A: The Intel Xeon 6315P supports DDR4 and DDR5 memory in dual-channel mode and includes ECC support. The AMD Ryzen 3 7320C supports only LPDDR5 in dual-channel mode with 88.0 GB/s bandwidth and lacks ECC.

Q: Which processor has the larger cache?

A: The Intel Xeon 6315P has significantly more cache: 1.25 MB L2 per core and 12 MB shared L3. The AMD Ryzen 3 7320C has 512 KB L2 per core and only 4 MB shared L3.

Q: Do both processors have integrated graphics?

A: No. The Intel Xeon 6315P has no integrated graphics (N/A), while the AMD Ryzen 3 7320C includes a Radeon 610M iGPU. This makes the Ryzen more suitable for systems without a discrete GPU.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Xeon 6315P is built on Raptor Lake architecture, specifically the Raptor Lake-R codename, using a 10 nm process from Intel's own foundry. It belongs to the Xeon 6 (Raptor Lake Refresh) generation and is manufactured on a 163 mm² die. The AMD Ryzen 3 7320C uses Zen 2 architecture with the Mendocino codename, fabricated by TSMC on a 6 nm process with a 100 mm² die.

Core configuration differs despite matching core counts. The Intel part offers 4 cores and 4 threads, meaning no simultaneous multithreading. The AMD part provides 4 cores and 8 threads, effectively doubling thread count. This is a critical architectural distinction: Intel relies on higher clock speeds, while AMD uses SMT to increase throughput.

Clock speeds reinforce this divergence. The Xeon 6315P has a 2.80 GHz base clock and a 4.70 GHz boost clock. The Ryzen 3 7320C operates at 2.40 GHz base and 4.10 GHz boost. Intel's clocks are substantially higher, which explains its dominance in single-threaded benchmarks.

Cache hierarchies are also starkly different. Intel allocates 80 KB L1 per core, 1.25 MB L2 per core, and 12 MB shared L3. AMD provides 64 KB L1 per core, 512 KB L2 per core, and just 4 MB shared L3. Intel's 12 MB L3 is three times larger than AMD's 4 MB.

Platform features diverge widely. The Xeon uses Intel Socket 1700, supports DDR4 and DDR5 memory, includes ECC, and offers PCIe Gen 5 with 16 CPU lanes. The Ryzen uses AMD Socket FT6, supports only LPDDR5 with 88.0 GB/s bandwidth, lacks ECC, and has PCIe Gen 3 with just 4 CPU lanes. The Ryzen is also a mobile part with a 15 W TDP, compared to the Xeon's 55 W server/workstation TDP.

The Verdict

The Intel Xeon 6315P is the clear performance winner in nearly every CPU-bound task. It leads by 44.2% in Cinebench R15 multi-core, 44.3% in R20 and R23 multi-core, and 44.3% in PassMark multithread. Single-core margins are even larger: 45.5% in R15, 44.2% in R20, 44.3% in R23, and 55.6% in PassMark single-thread. For any workload relying on raw CPU computation, the Xeon is the obvious choice.

The AMD Ryzen 3 7320C wins in three specific PassMark areas: data compression, integer math, and random string sorting. These wins are substantial, with leads of 18.1%, 16.1%, and 14.6% respectively. Additionally, the Ryzen includes a Radeon 610M iGPU, supports LPDDR5 memory, and draws only 15 W, making it suitable for low-power mobile systems.

The verdict depends on platform context. For a server or workstation where ECC memory, PCIe Gen 5, and maximum CPU performance are required, the Intel Xeon 6315P is the only sensible pick. For a thin-and-light laptop or embedded system where power efficiency, integrated graphics, and memory bandwidth are prioritized, the AMD Ryzen 3 7320C fills that role. The data shows no scenario where the Ryzen outperforms the Xeon in general computing; its wins are confined to specialized memory and integer workloads.

Head-to-Head Benchmarks

The Intel Xeon 6315P dominates the Cinebench suite with remarkable consistency. In Cinebench R15 multi-core, it scores 1021 against the Ryzen's 708, a 44.2% advantage. Single-core R15 shows 144 versus 99, a 45.5% lead. This pattern repeats across every Cinebench version: R20 multi-core (4256 vs 2950, +44.3%), R20 single-core (600 vs 416, +44.2%), R23 multi-core (10134 vs 7025, +44.3%), and R23 single-core (1430 vs 991, +44.3%). The consistency of the margin suggests a fundamental clock speed and IPC advantage for Intel.

PassMark multithread and single-thread results align with Cinebench. The Xeon scores 11923 in multithread versus 8265 for the Ryzen, a 44.3% lead. Single-thread is even more lopsided: 3795 versus 2439, a 55.6% advantage. Extended instructions show a massive 187.7% lead for Intel (10539 vs 3663), and floating-point math gives Intel a 138% edge (33496 vs 14071). Prime number finding is nearly one-sided: 150 versus 18, a 733.3% difference.

The AMD Ryzen 3 7320C claims three wins. Data compression is its strongest: 144465 versus 118313, an 18.1% lead. Integer math shows 32247 versus 27046, a 16.1% advantage. Random string sorting comes in at 16973 versus 14487, a 14.6% margin. Data encryption is nearly tied, with Intel edging out 5470 versus 5443, a mere 0.5% difference. Physics simulation also favors Intel heavily: 1156 versus 500, a 131.2% lead.

Where Each One Wins

The Intel Xeon 6315P wins in all rendering and compute-intensive scenarios. Cinebench R15, R20, and R23 results, both single and multi-core, favor Intel by roughly 44%. This makes it superior for 3D rendering, video encoding, and any task that scales with core clock speed. PassMark multithread, floating-point math, extended instructions, and prime number finding all show Intel with leads ranging from 44.3% to 733.3%. Physics simulation also belongs to Intel with a 131.2% margin.

The AMD Ryzen 3 7320C wins in three specific memory-related tasks. Data compression, integer math, and random string sorting are all workloads that benefit from its LPDDR5 memory bandwidth of 88.0 GB/s. These are not typical CPU performance tests but rather measure throughput in data manipulation. In these areas, the Ryzen outperforms the Xeon by 14.6% to 18.1%.

The Xeon also wins data encryption by a narrow 0.5% margin, making that test effectively a tie. For general productivity, the Intel part is the clear winner across the board. The Ryzen's wins are niche but real, suggesting its memory subsystem is better optimized for certain data-centric workloads.

For a server or workstation user, the choice is straightforward: the Xeon 6315P offers superior performance in 14 of 17 benchmarks, ECC memory support, PCIe Gen 5, and a 55 W TDP suitable for sustained loads. For a mobile user, the Ryzen 3 7320C provides integrated graphics, a 15 W TDP, and wins in data compression and integer math, making it viable for specific low-power applications. The data does not support choosing the Ryzen for raw compute, but its specialized wins and platform characteristics define its niche.
