CPU Comparison

The AMD Ryzen 3 1200 and Intel Xeon E5630 are both quad-core processors, but they target different eras and use cases. The data shows the Ryzen 3 1200 wins the majority of head-to-head comparisons, taking 2 out of 3 benchmarks, while the Xeon E5630 claims one decisive victory in a modern multi-threaded workload. The Ryzen 3 1200 is the clear choice for single-threaded performance and general desktop responsiveness, while the Xeon E5630’s sole win hints at sustained multi-core throughput. Neither processor holds a significant overall advantage, as both sit at the 31st percentile among all CPUs, and their average benchmark scores are nearly identical (1116 vs 1110). The Ryzen 3 1200 is the better pick for users prioritizing per-core speed and modern platform features, while the Xeon E5630 appeals to those needing consistent multi-threaded output, provided they can work within its older platform constraints.

The Verdict

From the benchmark data, the AMD Ryzen 3 1200 is the superior processor for most workloads. It delivers an 83.3% higher single-core score in Cinebench R23 (834 vs 455) and a 48.1% higher multi-core score in Cinebench R15 (480 vs 324). These are substantial margins that indicate a generational leap in per-core efficiency. The Ryzen 3 1200 is the right pick for anyone running applications that rely on single-threaded performance, such as older games, general productivity, or lightly threaded software. Its active production status and modern AM4 socket also mean it remains a viable current platform choice.

The Intel Xeon E5630, despite being end-of-life and from a 2010 release, wins the Cinebench R23 multi-core test with a score of 3226, beating the Ryzen 3 1200’s 3013 by 6.6%. This is its only victory, but it is not trivial. The Xeon’s 8 threads, enabled by Hyper-Threading, allow it to pull ahead in a modern, heavily multi-threaded benchmark. This makes it a niche option for users who run specific multi-threaded workloads and have access to cheap legacy hardware. However, its 80W TDP, triple-channel DDR3 memory, and locked multiplier make it less attractive for new builds. The data suggests the Ryzen 3 1200 is the more balanced, future-proof option, while the Xeon E5630 is a specialist for multi-core throughput on a budget legacy platform.

Architecture Differences

The two processors come from fundamentally different architectural eras. The AMD Ryzen 3 1200 is built on the Zen architecture, codenamed Summit Ridge, using a 14nm process node fabricated by GlobalFoundries. It integrates 4,800 million transistors on a 213 mm² die. The Intel Xeon E5630 uses the Westmere architecture, specifically Westmere-EP, on a 32nm Intel process, with 1,170 million transistors on a 239 mm² die. This explains the Ryzen’s massive transistor count advantage, over four times as many, packed into a slightly smaller die.

Cache configurations also differ significantly. The Ryzen 3 1200 provides 96 KB of L1 and 512 KB of L2 per core, plus an 8 MB shared L3 cache. The Xeon E5630 offers less L1 (64 KB per core) and L2 (256 KB per core) but compensates with a larger 12 MB shared L3 cache. The Ryzen’s larger per-core cache is likely a key factor in its superior single-core scores. Memory support is another major divergence: the Ryzen uses dual-channel DDR4 with a stated bandwidth of 42.7 GB/s, while the Xeon uses triple-channel DDR3 without a listed bandwidth figure. The Ryzen also features PCIe Gen 3 with 16 CPU lanes, whereas the Xeon has PCIe Gen 2. Both support ECC memory, but the Ryzen has an unlocked multiplier while the Xeon is locked. The Ryzen’s socket is AM4, the Xeon’s is 1366.

Where Each One Wins

The AMD Ryzen 3 1200 wins decisively in single-threaded workloads. Its Cinebench R23 single-core score of 834 is 83.3% higher than the Xeon’s 455. This indicates a massive advantage in tasks that cannot utilize multiple cores, such as many legacy applications, web browsing, and office productivity. The Ryzen also wins the older Cinebench R15 multi-core test, scoring 480 against the Xeon’s 324, a 48.1% lead. This suggests that in less modern multi-threaded tests, the Ryzen’s higher clock speeds and newer architecture dominate.

The Intel Xeon E5630 claims victory in the Cinebench R23 multi-core test, scoring 3226 versus the Ryzen’s 3013. This is a 6.6% advantage. The Xeon’s 8 threads versus the Ryzen’s 4 threads are the likely reason, allowing it to scale better in a highly parallel, modern rendering workload. The Xeon also has a larger 12 MB L3 cache, which may help in certain data-heavy scenarios. However, this is a single win, and the Ryzen’s wins are far more substantial in percentage terms. The data indicates the Ryzen is better for mixed workloads, while the Xeon is only preferable for specific, heavily multi-threaded tasks that favor its thread count.

Head-to-Head Benchmarks

The head-to-head data reveals a clear pattern of generational dominance countered by a thread-count advantage. The largest win for the AMD Ryzen 3 1200 comes in the Cinebench R23 single-core test. Here, the Ryzen scores 834, while the Xeon E5630 manages only 455. This results in a delta of 83.3%, the most significant performance gap in the entire comparison. This benchmark is a direct measure of per-core capability, and the Ryzen’s 3.10 GHz base and 3.40 GHz boost clocks, combined with the Zen architecture, utterly outclass the Xeon’s 2.53 GHz base and 2.80 GHz boost.

The Ryzen also wins the Cinebench R15 multi-core test, scoring 480 to the Xeon’s 324. This is a 48.1% advantage. Although both processors have 4 cores, the Ryzen’s lack of extra threads is not a penalty here; its superior IPC and clock speed allow it to finish well ahead. This older benchmark appears less sensitive to thread count than the newer R23.

The Intel Xeon E5630’s sole victory comes in the Cinebench R23 multi-core test. The Xeon scores 3226, beating the Ryzen’s 3013 by 6.6%. This is a surprising reversal given the R15 result. The likely explanation is that Cinebench R23 scales more effectively with the Xeon’s 8 threads. The Xeon’s additional threads allow it to overcome its lower per-core performance in this heavily parallelized, modern workload. Despite this win, the aggregate data still favors the Ryzen, which holds a 2-1 record in head-to-head benchmarks and wins by significantly larger margins overall.

Specification Differences

The specifications diverge sharply across almost every metric, reflecting their different release eras and market segments. The AMD Ryzen 3 1200 was released in 2017 and is still in active production, while the Intel Xeon E5630 was released in 2010 and is end-of-life. The Ryzen is a desktop part with a 65W TDP, while the Xeon is a server/workstation part with an 80W TDP. The Ryzen’s base clock is 3.10 GHz, boosting to 3.40 GHz, whereas the Xeon runs at 2.53 GHz base and 2.80 GHz boost. The Ryzen is built on a 14nm process, the Xeon on a 32nm process.

Memory and I/O also differ. The Ryzen uses dual-channel DDR4 with a memory bandwidth of 42.7 GB/s; the Xeon uses triple-channel DDR3 with no listed bandwidth. The Ryzen has PCIe Gen 3 with 16 lanes, while the Xeon has PCIe Gen 2. The cache hierarchy is different: the Ryzen has 96 KB L1 and 512 KB L2 per core, plus 8 MB shared L3; the Xeon has 64 KB L1 and 256 KB L2 per core, plus 12 MB shared L3. The Ryzen’s transistor count is 4,800 million on a 213 mm² die, while the Xeon has 1,170 million on a 239 mm² die. The Ryzen has an unlocked multiplier; the Xeon’s is locked. The Ryzen’s launch MSRP was $109, and its part number is YD1200BBM4KAEYD1200BBAEBOX, while the Xeon’s part number is SLBVB. Both support ECC memory and lack integrated graphics.
