AMD Ryzen Threadripper 1950X vs AMD Ryzen Threadripper 2950X Comparison

The AMD Ryzen Threadripper 1950X and the AMD Ryzen Threadripper 2950X are both formidable 16-core desktop processors, but the benchmark data separates them clearly. The 2950X wins every single recorded benchmark head-to-head, while the 1950X trails by a consistent margin across all tests. This is a straightforward generational upgrade, but the specifics of where and how the 2950X pulls ahead are worth examining for anyone deciding between them.

Where Each One Wins

The data is unambiguous on this front: the AMD Ryzen Threadripper 2950X wins all eight recorded benchmark comparisons. There are zero wins for the 1950X in the head-to-head results. The 2950X takes every Cinebench R15, R20, and R23 test, both single-core and multi-core, as well as both Geekbench tests.

That said, the 1950X still holds a position in the database as a capable 16-core processor. Its average benchmark score of 6231 places it in the 62nd percentile of all CPUs. The 2950X also sits in the 62nd percentile, but with a higher average score of 6647. The practical difference is that the 1950X is a solid workstation chip for heavily threaded workloads, while the 2950X is a refined version of the same idea.

The 2950X is the clear choice for anyone optimizing for raw performance in rendering, encoding, or any multi-threaded application. The 1950X, despite being older and slower, still offers the same 16-core, 32-thread topology, meaning it will not be left behind in core-count-heavy tasks. The wins are all with the 2950X, but the 1950X remains a relevant baseline for comparison.

FAQ

Q: Which processor has the higher boost clock?

A: The AMD Ryzen Threadripper 2950X boosts up to 4.40 GHz, while the 1950X reaches 4.00 GHz. The 2950X also has a higher base clock at 3.50 GHz compared to 3.40 GHz on the 1950X.

Q: Are both processors on the same socket?

A: Yes, both use the AMD Socket SP3r2. This means they are physically compatible with the same platform, though the 2950X is a later release with a different architecture.

Q: What is the biggest performance difference between them in multi-core tests?

A: The largest multi-core gap is in Geekbench, where the 2950X scores 8469 versus 7989 for the 1950X, a delta of 5.7%. In all Cinebench multi-core tests, the 2950X is consistently 6.4% ahead.

Q: Do both processors have the same amount of cache?

A: Yes, both have 96 KB of L1 cache per core, 512 KB of L2 cache per core, and a total of 32 MB of L3 cache. The cache configuration is identical.

Q: Is the 2950X more power-efficient?

A: Both processors have the same TDP of 180 watts. The 2950X delivers higher performance within that same power envelope due to its newer manufacturing process and architecture.

Q: Which processor has a higher average benchmark score?

A: The 2950X has an average benchmark score of 6647, compared to 6231 for the 1950X. This places the 2950X about 6.7% higher in overall average performance.

Head-to-Head Benchmarks

The head-to-head data shows a consistent pattern of the 2950X outperforming the 1950X by nearly the same percentage across all Cinebench tests. In Cinebench R15 multi-core, the 1950X scores 2362 against 2523 for the 2950X, a 6.4% deficit. The single-core R15 test shows a similar story: 333 versus 356, a 6.5% gap.

Moving to Cinebench R20, the multi-core scores are 9844 for the 1950X and 10516 for the 2950X, again a 6.4% difference. The R20 single-core test yields 1389 versus 1484, also a 6.4% delta. Cinebench R23 follows the same trend: multi-core scores are 23440 and 25040, while single-core scores are 3309 and 3535, both showing a 6.4% advantage for the 2950X.

The Geekbench results show a slightly smaller but still decisive gap. In Geekbench multi-core, the 1950X scores 7989, and the 2950X scores 8469, a 5.7% difference. Geekbench single-core shows 1183 versus 1255, also a 5.7% delta. Across all eight tests, the 2950X wins by a margin between 5.7% and 6.5%, with no test where the 1950X comes out ahead.

The consistency of these deltas is notable. It suggests the performance advantage is not workload-specific but rather a fundamental improvement in execution efficiency. The 2950X does not win because of a higher core count or more cache, it wins because each core can do more work per clock cycle.

Specification Differences

The two processors share many core specifications, but the key differences are in clock speeds and memory bandwidth. The 1950X has a base clock of 3.40 GHz and a boost clock of 4.00 GHz. The 2950X raises both to 3.50 GHz base and 4.40 GHz boost. This higher boost clock is the primary driver of the single-core performance advantage.

Memory bandwidth also differs. The 1950X has a recorded memory bandwidth of 85.3 GB/s, while the 2950X achieves 93.9 GB/s. Both support DDR4 memory in quad-channel mode, but the 2950X moves data faster, which can help in memory-sensitive workloads.

The PCIe configuration is listed for the 2950X as "Gen 3, 60 Lanes (CPU only)", while the 1950X has no PCIe data recorded in the database. This suggests the 2950X offers more explicit PCIe connectivity, though the exact lane count for the 1950X is not specified.

The release dates differ, with the 1950X launching on August 9, 2017, and the 2950X on August 30, 2018. The launch MSRP also differs: $999 for the 1950X and $899 for the 2950X. The part numbers are distinct, YD195XA8UGAAE for the 1950X and YD295XA8UGAAF for the 2950X.

Architecture Differences

The fundamental architectural difference is the process node and core design. The 1950X uses the Zen architecture on a 14 nm process from GlobalFoundries. The 2950X moves to the Zen+ architecture on a 12 nm process, also from GlobalFoundries. This shrink allows for higher clock speeds without increasing the 180 watt TDP.

The codenames reflect this change: the 1950X is from the Zen (Whitehaven) generation, while the 2950X is from the Zen+ (Colfax) generation. Despite the architectural update, both processors use two dies, each with a die size of 213 mm², and both have 9,600 million transistors. The cache layout is identical: 96 KB L1 per core, 512 KB L2 per core, and 32 MB of L3 total.

The 2950X benefits from the Zen+ refinements, which include improved clock ramping and lower latencies. This is why it can sustain higher boost clocks and achieve better single-core scores. The 1950X, being a first-generation Zen part, does not have these optimizations. Both are unlocked for overclocking, and both lack integrated graphics, relying on discrete GPUs.

The memory bus remains quad-channel for both, but the 2950X's higher bandwidth figure indicates a more efficient memory controller. Neither supports ECC memory according to the database. The socket is the same, SP3r2, meaning the 2950X is a drop-in replacement for systems designed for the 1950X, assuming the BIOS is updated.

The Verdict

The data points to a clear recommendation: choose the AMD Ryzen Threadripper 2950X if you want the best performance available in this 16-core class. It wins every benchmark by a margin of 5.7% to 6.5%, and it does so with the same TDP and cache configuration. The higher clock speeds and refined Zen+ architecture deliver a measurable improvement across both single-threaded and multi-threaded workloads.

The 1950X is not a poor processor, it is simply an older one. Its 16 cores and 32 threads still place it in the 62nd percentile of all CPUs, and its average benchmark score of 6231 is respectable. For users who already own a 1950X, the upgrade to the 2950X offers a consistent 6% performance uplift, which is meaningful but not transformative. For new buyers, the 2950X is the better purchase, especially given its higher memory bandwidth and faster boost clock.

If the use case is heavily multi-threaded rendering or encoding, the 2950X's multi-core lead of 6.4% in Cinebench R23 translates to real time savings. If the workload is more mixed, the single-core advantage of 6.5% in Cinebench R15 ensures snappier response in less parallel tasks. There is no scenario in the recorded data where the 1950X is the better choice. The verdict is simple: the 2950X is the superior processor, and the 1950X remains a capable but superseded option.
