AMD Ryzen 3 1200 vs Intel Core i5-3550S Comparison

The Verdict

The data presents a clear but nuanced picture. The AMD Ryzen 3 1200 wins the majority of head-to-head benchmarks, taking 3 out of 4 tests, but the Intel Core i5-3550S delivers one decisive counterpunch. If you prioritize modern single-threaded performance and the flexibility of an unlocked multiplier, the Ryzen 3 1200 is the obvious choice. Its single-core scores are dramatically higher, and it even leads in Cinebench R15 multi-core. However, the i5-3550S strikes back hard in Cinebench R23 multi-core, where it leads by 26.4%. This means the choice depends heavily on which workload generation you care about. For older software and classic multi-threaded rendering, the Intel part holds its ground; for newer applications and general responsiveness, the AMD part is superior. The Ryzen 3 1200 also benefits from being a much newer design with modern platform support, making it the more practical recommendation for a new build today.

Architecture Differences

These two processors come from completely different eras and design philosophies. The Intel Core i5-3550S is built on the Ivy Bridge architecture using Intel's 22 nm process, featuring a transistor count of 1,400 million on a 160 mm² die. The AMD Ryzen 3 1200, in contrast, uses the Zen architecture fabricated by GlobalFoundries on a 14 nm process, packing 4,800 million transistors into a 213 mm² die. That is a massive difference in transistor density and count, reflecting the generational gap between 2012 and 2017 designs.

Both CPUs feature 4 cores and 4 threads, so there is no difference in raw thread count. However, the memory ecosystems are entirely different. The i5-3550S supports DDR3 memory, while the Ryzen 3 1200 supports DDR4 with a specified memory bandwidth of 42.7 GB/s. The Ryzen also supports ECC memory, which the Intel chip does not. Cache hierarchies differ too: the Intel part has 64 KB of L1 and 256 KB of L2 per core, with 6 MB of shared L3. The AMD part has 96 KB of L1 and 512 KB of L2 per core, with a larger 8 MB of shared L3. The Ryzen 3 1200 has an unlocked multiplier, while the i5-3550S is locked. The Intel chip includes integrated graphics (Intel HD 2500), while the Ryzen has none. Both use PCIe Gen 3 with 16 lanes from the CPU, but they sit on different sockets: Intel Socket 1155 versus AMD Socket AM4.

FAQ

Q: Can I overclock the AMD Ryzen 3 1200?

A: Yes, the Ryzen 3 1200 has an unlocked multiplier, so overclocking is supported. The Intel Core i5-3550S has a locked multiplier and does not offer this flexibility.

Q: Are both CPUs in the same performance percentile?

A: Yes, both processors are at the 31st percentile versus all CPUs according to benchmark data. Their average benchmark scores are nearly identical: 1118 for the Intel and 1116 for the AMD.

Q: Which CPU has integrated graphics?

A: Only the Intel Core i5-3550S has integrated graphics, specifically Intel HD 2500. The AMD Ryzen 3 1200 has no integrated graphics, so a discrete GPU is required.

Specification Differences

The two chips differ in nearly every specification category. The Intel Core i5-3550S uses a 22 nm process node, while the AMD Ryzen 3 1200 uses a larger 14 nm node. Transistor counts differ substantially: 1,400 million for Intel versus 4,800 million for AMD. Die size is 160 mm² for Intel and 213 mm² for AMD. Base clocks are 3.00 GHz versus 3.10 GHz in favor of AMD, but boost clocks favor Intel at 3.70 GHz versus 3.40 GHz.

Memory support is a major differentiator: Intel uses DDR3, AMD uses DDR4 with a rated bandwidth of 42.7 GB/s. ECC memory is supported only on the AMD chip. Cache configurations differ across all levels: L1 is 64 KB per core on Intel versus 96 KB per core on AMD; L2 is 256 KB per core versus 512 KB per core; L3 is 6 MB shared versus 8 MB shared. The AMD Ryzen 3 1200 has an unlocked multiplier; the Intel chip does not. Integrated graphics are present only on the Intel part. The release dates are 2012-04-28 for Intel and 2017-07-26 for AMD. The AMD chip has a launch MSRP of $109 and is still marked as Active in production status, while the Intel part has no specified production status.

Head-to-Head Benchmarks

The benchmark results reveal a fascinating split between older and newer test versions. In Cinebench R15 multi-core, the AMD Ryzen 3 1200 scores 480 against the Intel's 383, a 20.2% advantage for AMD. The single-core R15 test is even more lopsided: AMD scores 135 versus Intel's 54, a 60% difference. These are massive margins that show the Zen architecture's superior instruction efficiency and per-core performance.

However, the tables turn in Cinebench R23. In the multi-core test, the Intel Core i5-3550S scores 3808 versus AMD's 3013, giving Intel a 26.4% lead. This is a remarkable reversal. The Intel chip, despite being older and having a lower base clock, outperforms in this newer rendering workload. But in R23 single-core, AMD again dominates with a score of 834 versus Intel's 537, a 35.6% margin.

The overall win count is 3 wins for AMD and 1 win for Intel. The average benchmark scores are nearly identical: 1118 for Intel and 1116 for AMD, with a delta of just 0.2%. This near-parity in aggregate benchmarks, combined with wildly different individual test results, suggests that workload characteristics matter enormously here. The Intel chip appears to scale well with multi-threaded workloads that benefit from its architecture, while the AMD chip excels at per-thread performance. The fact that Intel wins R23 multi-core by 26.4% after losing R15 multi-core by 20.2% indicates that the newer test suite favors the Ivy Bridge design's strengths, possibly due to different instruction mixes or memory access patterns.

Where Each One Wins

The AMD Ryzen 3 1200 is the clear winner for single-threaded performance across all tested generations. It leads by 60% in Cinebench R15 single-core and by 35.6% in Cinebench R23 single-core. This translates to snappier everyday responsiveness, faster single-threaded application performance, and better performance in games or software that rely heavily on one or two threads. The Ryzen also wins in Cinebench R15 multi-core by 20.2%, which suggests it handles older multi-threaded workloads efficiently. Combined with its DDR4 memory support, ECC capability, and unlocked multiplier, the Ryzen 3 1200 is the better choice for a modern, flexible system where overclocking and newer memory standards are desired.

The Intel Core i5-3550S wins decisively in Cinebench R23 multi-core, leading by 26.4% with a score of 3808 versus 3013. This is a significant margin that suggests the Ivy Bridge architecture handles the newer R23 workload particularly well, possibly due to better cache utilization or instruction scheduling. If your primary application is a modern multi-threaded renderer that resembles R23, the Intel chip would be the stronger performer. The i5-3550S also includes integrated graphics, which means it can function without a discrete GPU for basic display output. Its higher boost clock of 3.70 GHz may also give it an edge in bursty workloads that benefit from short boosts.

For sheer benchmark dominance, the Ryzen 3 1200 wins 3 out of 4 tests. The Intel part wins only one test, but that one test is by a large margin. If you are building a system for modern productivity and gaming, the data clearly favors the AMD chip. If you have a specific workload that matches the R23 multi-core pattern and you want to avoid buying a discrete GPU, the Intel chip has a compelling case. The near-identical average benchmark scores (1118 versus 1116) mean that for general mixed usage, neither CPU will feel dramatically faster than the other in aggregate. The choice comes down to your specific workload priorities and platform preferences.
