AMD Ryzen Threadripper 2950X vs Intel Core i9-7980XE Comparison

Head-to-Head Benchmarks

The head-to-head data shows a clear sweep for the Intel Core i9-7980XE, winning all eight recorded benchmark comparisons. However, the margin of victory varies dramatically depending on the workload. In the Cinebench suite, the two processors are effectively tied, with the Intel part taking razor-thin leads of 0.2% or less. The largest gap in that suite is the Cinebench R15 multicore test, where the Intel scores 2527 against AMD's 2523, a delta of just 0.2%. The R20 multicore test shows 10530 versus 10516, a 0.1% edge, and the R23 multicore test records 25072 against 25040, again a 0.1% difference. Single-core results in Cinebench are nearly identical as well: R15 shows a perfect tie at 356, while R20 and R23 show Intel leading by 0.1% each time.

The story changes completely in Geekbench. The Intel Core i9-7980XE posts a multicore score of 11198 against AMD's 8469, a decisive 32.2% advantage. That is the single largest delta recorded in the head-to-head data. The single-core Geekbench result also favors Intel, with 1435 versus 1255, a 14.3% lead. The data indicates that Geekbench is far more sensitive to the architectural differences between these two processors than Cinebench is. In Cinebench, the extra two cores and four threads of the Intel chip appear to be offset by the AMD part's higher base clock, resulting in near parity. In Geekbench, the Intel architecture holds a commanding edge that the AMD part cannot overcome.

Across all eight tests, the Intel Core i9-7980XE wins every comparison, but the meaningful performance separation is concentrated in the Geekbench results. The Cinebench results suggest that for rendering workloads, users would see virtually identical performance from either processor. The Geekbench results, meanwhile, point to a substantial Intel advantage in tasks that exercise the CPU in ways that align with that benchmark's methodology.

Architecture Differences

The two processors come from fundamentally different design lineages. The Intel Core i9-7980XE is built on the Skylake architecture, specifically the Skylake-X codename, and falls into the Core i9 Extreme generation of the X-Series 7th Gen lineup. It uses a 14 nm process node manufactured by Intel, with a die size of 484 mm². The AMD Ryzen Threadripper 2950X uses the Zen+ architecture under the Colfax codename and belongs to the Ryzen Threadripper generation. It is built on a 12 nm process at GlobalFoundries, with a die size of 2x 213 mm² and a transistor count of 9,600 million.

The core counts differ, with the Intel part offering 18 cores and 36 threads, while the AMD part offers 16 cores and 32 threads. Cache layouts are organized differently as well. The Intel chip provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and a shared 24.75 MB L3 cache. The AMD chip provides 96 KB of L1 per core, 512 KB of L2 per core, and a 32 MB shared L3 cache. The larger per-core L2 on the Intel side and the larger shared L3 on the AMD side reflect their respective design priorities.

Memory bandwidth also differs despite both using quad-channel DDR4. The AMD processor records 93.9 GB/s of memory bandwidth, while the Intel processor records 85.3 GB/s. The Intel chip supports 44 PCIe Gen 3 lanes from the CPU, whereas the AMD chip supports 60 PCIe Gen 3 lanes, giving the AMD platform more room for expansion devices. Neither processor includes integrated graphics, and neither supports ECC memory. The AMD part is manufactured with 9,600 million transistors spread across two dies, while the Intel part uses a single monolithic die of 484 mm². The Intel chip is marked as end-of-life, while the AMD chip remains active in production.

Specification Differences

The two processors differ across several specification fields. The Intel Core i9-7980XE has 18 cores and 36 threads, while the AMD Ryzen Threadripper 2950X has 16 cores and 32 threads.

Where Each One Wins

The Intel Core i9-7980XE wins every head-to-head benchmark in the recorded data, but the nature of those wins matters for real-world use. In Geekbench multicore, the Intel part is 32.2% ahead, which is a substantial margin that indicates a strong advantage in workloads that scale with the architectural efficiency measured by that test. The Geekbench single-core result also favors Intel by 14.3%, suggesting that the Intel core design holds an edge in lightly threaded tasks that depend on per-core performance.

The AMD Ryzen Threadripper 2950X wins no direct benchmark comparisons, but the Cinebench results show that it is effectively tied with the Intel part in rendering workloads. The 0.1% to 0.2% deltas in the Cinebench suite are within noise territory, meaning users running Cinebench-style workloads would see no practical difference between the two. The AMD part also offers 60 PCIe lanes versus Intel's 44, which is a specification advantage for systems needing more expansion slots or storage devices. The AMD chip records higher memory bandwidth at 93.9 GB/s versus 85.3 GB/s, which could matter in memory-bandwidth-sensitive applications.

The AMD part has a higher base clock of 3.50 GHz against Intel's 2.60 GHz, which helps close the gap in multi-threaded rendering despite having two fewer cores. The Intel part compensates with 18 cores against 16, plus a larger per-core L2 cache. For users prioritizing Geekbench-style performance, the Intel part is clearly superior. For users prioritizing rendering throughput in Cinebench, the choice between the two makes no measurable difference.

The Verdict

The data points to the Intel Core i9-7980XE as the stronger performer overall, with an average benchmark score of 7018 against the AMD part's 6647. The Intel chip wins all eight head-to-head tests, and its Geekbench multicore lead of 32.2% is the defining gap in the comparison. Users who rely on applications that resemble Geekbench workloads should choose the Intel part without hesitation.

The AMD Ryzen Threadripper 2950X is the better pick for users who value the specifications where it leads: 60 PCIe lanes, higher memory bandwidth at 93.9 GB/s, a higher base clock at 3.50 GHz, and a more modern 12 nm process. Its Cinebench performance is statistically indistinguishable from the Intel part, so rendering workloads will not favor either chip. The AMD part also remains active in production, while the Intel part is end-of-life, and the AMD launch MSRP of $899 is lower than the Intel launch MSRP of $1999. Users who need Geekbench-class performance should take the Intel Core i9-7980XE. Users who want comparable rendering performance with more PCIe expansion capability and an active production status should take the AMD Ryzen Threadripper 2950X.
