Architecture Differences

The two processors come from different eras of AMD's lineup and use fundamentally different silicon. The Ryzen 7 PRO 3700 belongs to the 3000 series and uses the Zen 2 architecture with the Matisse codename, built on TSMC's 7 nm process. It packs 3,800 million transistors into a 74 mm² die. In contrast, the Threadripper 1920X is from the 1000 series, uses the original Zen architecture with the Whitehaven codename, and is manufactured by GlobalFoundries on a 14 nm process. Its transistor count is 9,600 million spread across two 213 mm² dies.

The core layouts differ significantly. The Ryzen 7 PRO 3700 has 8 cores and 16 threads, while the Threadripper 1920X offers 12 cores and 24 threads. Each core in the Ryzen 7 PRO 3700 has 64 KB of L1 cache and 512 KB of L2 cache; the Threadripper's cores have 96 KB of L1 cache and 512 KB of L2 cache. Both share a 32 MB L3 cache, so the Ryzen 7 PRO 3700 actually offers a larger L3 pool relative to its core count.

The sockets and platforms are entirely different. The Ryzen 7 PRO 3700 uses AMD Socket AM4, while the Threadripper 1920X uses AMD Socket SP3r2. Memory architecture also diverges: the Ryzen 7 PRO 3700 runs dual-channel DDR4 with 51.2 GB/s of bandwidth, whereas the Threadripper 1920X runs quad-channel DDR4 with 85.3 GB/s. Neither processor supports ECC memory according to the recorded specs.

PCIe capabilities show a notable generational gap. The Ryzen 7 PRO 3700 provides PCIe Gen 4 with 24 CPU lanes, while the Threadripper 1920X uses PCIe Gen 3 with 60 CPU lanes. Threadripper offers far more lanes, but the Ryzen 7 PRO 3700 has the newer standard.

Power characteristics differ sharply. The Ryzen 7 PRO 3700 has a 65 W TDP, while the Threadripper 1920X is rated at 180 W. The Threadripper's higher core count and older 14 nm process explain the much larger power envelope. Clock speeds also favor the newer chip: the Ryzen 7 PRO 3700 has a 3.60 GHz base and 4.40 GHz boost, versus 3.50 GHz base and 4.00 GHz boost for the Threadripper.

Both processors have an unlocked multiplier, making them flexible for overclocking. The Ryzen 7 PRO 3700 was released in 2019, while the Threadripper 1920X launched in 2017. Both are still marked as Active in production status.

Head-to-Head Benchmarks

The head-to-head results tell a consistent story across all six Cinebench comparisons. The Threadripper 1920X wins every single test, though by narrow margins. In Cinebench R15 multi-core, the Threadripper scores 1,979 against the Ryzen 7 PRO 3700's 1,955, a 1.2% lead. The single-core R15 test shows 279 versus 275, a 1.4% edge for the Threadripper.

Moving to Cinebench R20, the pattern holds. Multi-core sees the Threadripper at 8,248 and the Ryzen 7 PRO 3700 at 8,146, again a 1.2% difference. Single-core R20 gives the Threadripper 1,164 against 1,149, a 1.3% margin.

Cinebench R23 repeats the same arithmetic. Multi-core: 19,640 for the Threadripper versus 19,397 for the Ryzen 7 PRO 3700, a 1.2% gap. Single-core: 2,772 versus 2,738, a 1.2% gap. The Threadripper wins all six recorded head-to-head matchups.

These margins are remarkably consistent, hovering around 1.2% to 1.4% across every test. The Threadripper's 12-core advantage in multi-core workloads should theoretically produce a larger gap, but the Ryzen 7 PRO 3700's newer Zen 2 architecture and higher boost clock of 4.40 GHz clearly close the distance. The Threadripper's older Zen cores need more cores just to stay ahead.

The average benchmark scores put the Ryzen 7 PRO 3700 ahead overall, at 5,610 versus 5,306 for the Threadripper. This reflects the fact that the Ryzen 7 PRO 3700 sits at the 61st percentile of all CPUs, while the Threadripper sits at the 60th. The Ryzen 7 PRO 3700's nearest rival in the database is the Intel Core i7-12700T with an average score of 5,606 (0.1% difference), followed by the Intel Atom x7433RE at 5,601 (0.2%) and the Intel Core i9-11900KB at 5,587 (0.4%). The Threadripper's closest comparison is the AMD EPYC 7281 at 5,315 (0.2% ahead), the Intel Core i9-9900X at 5,301 (0.1% behind), and the Intel Core i9-10900KF at 5,316 (0.2% behind).

The Geekbench results, only recorded for the Threadripper, show 7,178 multi-core and 1,185 single-core. No direct Geekbench comparison exists in the database for the Ryzen 7 PRO 3700.

The Verdict

The data presents an unusual picture. The Threadripper 1920X wins every direct head-to-head benchmark, but the margins are so small that the victories feel almost symbolic rather than practical. A 1.2% lead in Cinebench R23 multi-core, going from 19,397 to 19,640, is within run-to-run variance for most testing scenarios. The Threadripper's 12 cores and 24 threads should dominate a 8-core, 16-thread part in heavily threaded workloads, yet the Ryzen 7 PRO 3700's Zen 2 architecture and 4.40 GHz boost clock nearly erase that advantage.

The Ryzen 7 PRO 3700 is the more efficient choice by a wide margin. Its 65 W TDP versus 180 W means far lower power draw, and it still delivers within 1.2% of the Threadripper in multi-core Cinebench tests. The newer 7 nm process, the smaller 74 mm² die, and the higher clock speeds all point to a more modern and refined design.

The Threadripper 1920X makes sense only for a specific user. Its quad-channel memory with 85.3 GB/s bandwidth is a real advantage for memory-intensive workloads, and its 60 PCIe Gen 3 lanes offer far more expansion capability than the Ryzen 7 PRO 3700's 24 Gen 4 lanes. The launch MSRP for the Threadripper 1920X is $799. Users who need massive memory bandwidth, extensive PCIe connectivity, or the Threadripper platform itself will find the 12-core part compelling.

For everyone else, the Ryzen 7 PRO 3700 is the better overall processor. It matches the Threadripper in benchmark performance within a couple of percentage points, uses dramatically less power, and represents the newer architecture generation. The database's average benchmark scores confirm this: 5,610 for the Ryzen 7 PRO 3700 versus 5,306 for the Threadripper, putting the Ryzen 7 PRO 3700 at a higher percentile of all CPUs.
