This analysis covers the numbers, the specification gaps, and the use cases each processor serves.

FAQ

Q: Which processor has higher multi-core performance?

A: The Intel Xeon E3-1285L v4 wins every multi-core Cinebench test. In Cinebench R15, it scores 693 against 649 for the Ryzen 3 2300X, a 6.8% lead. In R20, the scores are 2891 versus 2706, also 6.8%. In R23, Intel scores 6884 versus 6443, again 6.8%.

Q: Which processor has higher single-core performance?

A: Intel also leads in single-core. In Cinebench R15 single-core, Intel scores 97 versus 91, a 6.6% advantage. In R20 single-core, Intel scores 407 versus 381, a 6.8% lead. In R23 single-core, Intel scores 971 versus 909, a 6.8% margin.

Q: Which processor supports ECC memory?

A: The Intel Xeon E3-1285L v4 supports ECC memory. The AMD Ryzen 3 2300X does not.

Q: Which processor has integrated graphics?

A: The Intel Xeon E3-1285L v4 includes Intel Iris Pro P6300 integrated graphics. The AMD Ryzen 3 2300X has no integrated graphics, so a discrete GPU is required.

Q: Which processor has more threads?

A: The Intel Xeon E3-1285L v4 has 8 threads (4 cores with SMT). The AMD Ryzen 3 2300X has 4 threads (4 cores without SMT).

Q: Which processor has higher memory bandwidth?

A: The AMD Ryzen 3 2300X has a memory bandwidth of 46.9 GB/s, while the Intel Xeon E3-1285L v4 has 29.9 GB/s. This is due to the Ryzen's DDR4 support versus Intel's DDR3.

The Verdict

The data is unambiguous: the Intel Xeon E3-1285L v4 wins all six Cinebench benchmarks, with margins of 6.6% to 6.8%. Its 8 threads and higher per-core efficiency overcome the Ryzen's higher clock speeds (3.5/4.0 GHz versus 3.4/3.8 GHz). For any workload measured by Cinebench, the Intel part is the faster choice.

However, the Ryzen 3 2300X brings a modern platform: DDR4 memory, a higher memory bandwidth of 46.9 GB/s, and an unlocked multiplier. It also has a smaller process node (12 nm versus 14 nm) and a larger transistor count (4,800 million versus 1,400 million). But these advantages do not translate into higher Cinebench scores. The Intel part also offers ECC support and integrated graphics, which the Ryzen lacks.

For users who prioritize Cinebench performance, the Intel Xeon E3-1285L v4 is the clear pick. For those who need DDR4, higher memory bandwidth, or an unlocked multiplier, the Ryzen offers those features, but its benchmark scores are lower. The Intel part is end-of-life, while the Ryzen is active, but the recorded data shows Intel's performance edge.

Head-to-Head Benchmarks

The head-to-head results are one-sided. The Intel Xeon E3-1285L v4 wins all six tests, with no wins for the AMD Ryzen 3 2300X.

In Cinebench R15 multi-core, Intel scores 693 versus 649, a 6.8% advantage. In single-core, Intel scores 97 versus 91, a 6.6% lead. The R20 tests show the same pattern: multi-core 2891 versus 2706 (6.8%), single-core 407 versus 381 (6.8%). The R23 tests continue the trend: multi-core 6884 versus 6443 (6.8%), single-core 971 versus 909 (6.8%).

The consistency of the delta is notable. Every test except R15 single-core shows exactly 6.8% difference. This suggests a stable performance gap across different Cinebench versions and workload types. The Intel part's 8 threads give it a clear advantage in multi-threaded tests, while its single-core efficiency also outpaces the Ryzen despite the Ryzen's higher boost clock of 4.00 GHz versus 3.80 GHz.

Specification Differences

The two processors differ in nearly every specification except core count and TDP.

The Intel part has a higher thread count, ECC support, and integrated graphics. The AMD part has higher clocks, a smaller process node, more transistors, a larger die, more L1 and L2 cache per core, DDR4 support, higher memory bandwidth, and an unlocked multiplier.

Architecture Differences

The architectural gap is significant. The Intel Xeon E3-1285L v4 uses the Broadwell architecture on a 14 nm process, built by Intel. The AMD Ryzen 3 2300X uses the Zen architecture (specifically Zen+ Pinnacle Ridge) on a 12 nm process, built by GlobalFoundries.

The Intel part has 4 cores and 8 threads, thanks to SMT. The AMD part has 4 cores and 4 threads, no SMT. This thread advantage is a key reason for Intel's multi-core wins.

Cache layouts differ. Intel provides 64 KB L1 and 256 KB L2 per core, with 6 MB shared L3. AMD provides 96 KB L1 and 512 KB L2 per core, but only 4 MB shared L3. The larger L3 on Intel may help in some workloads, though the benchmark data does not isolate cache effects.

Memory support is a major divergence. Intel uses DDR3 with a dual-channel bus and 29.9 GB/s bandwidth. AMD uses DDR4 with a dual-channel bus and 46.9 GB/s bandwidth. The higher bandwidth on AMD does not translate into Cinebench wins, but it could benefit other memory-intensive tasks.

Intel includes an integrated GPU (Iris Pro P6300), while AMD has none. Intel also supports ECC memory, a feature absent on the Ryzen. The Intel part is a server/workstation product, while the Ryzen is a desktop part. The Intel part is end-of-life, while the Ryzen is active.

Where Each One Wins

Based on the recorded benchmarks, the Intel Xeon E3-1285L v4 wins every Cinebench test. For users who rely on Cinebench scores as a proxy for rendering or multi-threaded productivity, the Intel part is the superior choice. Its 8 threads and consistent 6.8% lead across R15, R20, and R23 make it the clear performance winner in these workloads.

The AMD Ryzen 3 2300X does not win any of the six head-to-head tests. However, it offers features that the Intel part lacks. Its DDR4 support and 46.9 GB/s memory bandwidth are significantly higher than Intel's 29.9 GB/s. The unlocked multiplier allows user-controlled frequency adjustments, though no overclocking results are recorded. The Ryzen also has a smaller process node and a larger transistor count, which may indicate better efficiency in other tasks, but the Cinebench data does not reflect that.

For users who need ECC memory or integrated graphics, the Intel part is the only option. For users who need DDR4, higher memory bandwidth, or an unlocked multiplier, the Ryzen provides those, but at the cost of lower Cinebench performance. The Ryzen also requires a discrete GPU, while the Intel part can output video through its Iris Pro P6300.

In summary, the Intel Xeon E3-1285L v4 wins on every measured benchmark. The AMD Ryzen 3 2300X wins on platform features and memory bandwidth, but not on Cinebench scores. The choice depends on whether benchmark performance or platform features matter more.
