CPU Comparison

The AMD Ryzen Threadripper 1920X and the Intel Core i7-11700B represent two very different answers to the same question: how to deliver high multi-threaded throughput. The Threadripper is a 2017-era desktop flagship built on a 14 nm process with 12 cores, while the i7-11700B is a 2021 mobile-class part on Intel’s 10 nm Tiger Lake-H architecture with 8 cores. Across the six head-to-head benchmarks in the data, the AMD part wins every single test. The margins are consistent, hovering near 8.4% in most cases. The average benchmark scores tell a similar story: the Threadripper 1920X sits at 5306, while the i7-11700B trails at 5241. Both parts land at the 60th percentile among all CPUs, but the data shows the Threadripper has a clear, if modest, edge in raw performance.

Head-to-Head Benchmarks

The most decisive victories for the AMD Ryzen Threadripper 1920X come in the Cinebench suite. In Cinebench R15 multicore, the Threadripper scores 1979 against the Intel’s 1826, a delta of 8.4%. The single-core R15 test shows an even slightly larger gap: 279 versus 257, an 8.6% advantage. This pattern repeats in R20, where the AMD part scores 8248 multicore and 1164 single-core, versus 7609 and 1074 for the Intel. The deltas are identical at 8.4% for both metrics. The trend continues into R23: the Threadripper posts 19640 multicore and 2772 single-core, while the i7-11700B manages 18119 and 2558. Again, the delta is 8.4% in both cases.

What is notable is the uniformity of the margin. Whether the workload scales across all cores or runs on a single thread, the Threadripper 1920X maintains roughly the same lead. This suggests the performance difference is not tied to core count scaling or clock behavior, but rather to a fundamental per-thread efficiency advantage in the AMD design. The Intel part’s higher boost clock of 4.80 GHz compared to the AMD’s 4.00 GHz does not translate into a win in any single-threaded test. In fact, the Threadripper’s single-core R23 score of 2772 is 8.4% higher than the i7-11700B’s 2558, despite the lower rated boost frequency.

There are no benchmark results in which the Intel part wins. The head-to-head table lists six wins for AMD and zero for Intel. The closest the i7-11700B comes is in the average score comparison, where the delta between the two parts is 65 points (5306 versus 5241), which is about 1.2%. However, the individual test deltas are all larger, meaning the average is pulled by the Geekbench results. The Threadripper’s Geekbench multicore score is 7178 and single-core is 1185; no Geekbench data is provided for the Intel part, so the head-to-head comparison rests entirely on the Cinebench tests.

The Verdict

From the data alone, the AMD Ryzen Threadripper 1920X is the faster processor in every measured workload. It leads by 8.4% in multicore and single-core Cinebench tests across R15, R20, and R23. The Intel Core i7-11700B does not win a single benchmark in the provided set. If the decision is purely about peak performance in CPU-bound rendering tasks, the Threadripper is the clear choice. The 12-core, 24-thread configuration, combined with 32 MB of L3 cache, delivers a consistent advantage over the 8-core, 16-thread Intel part with 24 MB of shared L3.

However, the context matters. The Threadripper 1920X carries a 180 W TDP, while the i7-11700B is rated at 65 W. The AMD part also uses a quad-channel memory bus with 85.3 GB/s bandwidth, versus the Intel’s dual-channel 51.2 GB/s. The AMD chip is a desktop part on Socket SP3r2, whereas the Intel chip is a mobile part on BGA 1787. For a system builder targeting a high-end desktop workstation, the Threadripper’s performance margin justifies its higher power envelope. For a mobile or compact platform, the i7-11700B offers a lower power draw and integrated graphics, but the benchmark data shows it sacrifices roughly 8% performance to do so.

The percentile rankings are identical at 60, which indicates that both parts sit in the same performance tier relative to all CPUs. The nearest rivals for each confirm this: the Threadripper’s closest competitor is the Intel Core i9-9900X with an average score of 5301, a delta of 0.1%. The i7-11700B’s closest rival is the Intel Core i9-10850K at 5240, with a delta of 0%. In other words, the Threadripper is essentially tied with the i9-9900X, and the i7-11700B is essentially tied with the i9-10850K. The gap between those two rival pairs is the same ~1.2% average gap seen between the two CPUs in question.

Architecture Differences

The underlying architectures diverge sharply. The AMD Ryzen Threadripper 1920X is built on the Zen microarchitecture, codenamed Whitehaven, using a 14 nm process from GlobalFoundries. It packs 9,600 million transistors across a die size of 2x 213 mm². The Intel Core i7-11700B uses the Tiger Lake-H architecture, also known as Tiger Lake, on Intel’s 10 nm process, with a die size of 190 mm². The transistor count for the Intel part is not listed, but the physical design is a single-die solution versus the AMD’s dual-die layout.

Core and cache configurations differ substantially. The Threadripper has 12 cores and 24 threads, with 96 KB of L1 per core, 512 KB of L2 per core, and 32 MB of L3. The i7-11700B has 8 cores and 16 threads, with 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3. The AMD part has more aggregate L3, but the Intel part has a larger per-core L2 cache. Neither supports ECC memory.

Memory and I/O also differ. The Threadripper supports DDR4 in a quad-channel configuration with 85.3 GB/s of bandwidth. The i7-11700B also supports DDR4 but in a dual-channel layout, delivering 51.2 GB/s. PCIe capabilities are another differentiator: the AMD part offers Gen 3 with 60 lanes from the CPU, while the Intel part offers Gen 4 with 20 lanes. The Intel part includes integrated UHD Graphics (Xe-LP), whereas the AMD part has no integrated graphics.

The production statuses are opposite. The Threadripper 1920X is listed as Active, while the i7-11700B is End-of-life. The release dates are also far apart: August 2017 for the AMD part, May 2021 for the Intel part. The AMD chip has an unlocked multiplier, while the Intel chip is locked. The launch MSRP for the Threadripper is $799; no launch MSRP is listed for the Intel part. The Intel part is a mobile-market segment CPU, while the AMD part is for desktop.

Where Each One Wins

The AMD Ryzen Threadripper 1920X wins in every benchmark category present in the data. In Cinebench R15 multicore, it scores 1979 versus 1826. In R20 multicore, it scores 8248 versus 7609. In R23 multicore, it scores 19640 versus 18119. It also wins all single-core tests: 279 versus 257 in R15, 1164 versus 1074 in R20, and 2772 versus 2558 in R23. The Geekbench scores for the Threadripper (7178 multicore, 1185 single-core) are also listed, though no direct comparison is available for the Intel part. The consistency of the 8.4% margin means the Threadripper is the better choice for any CPU-bound rendering, encoding, or multi-threaded compute workload where power draw is not the primary constraint.

The Intel Core i7-11700B does not win any of the head-to-head benchmarks. Its advantages are not in raw performance but in platform characteristics. It has a 65 W TDP versus the Threadripper’s 180 W, making it a lower-power option. It also includes integrated graphics, which the AMD part lacks. The Intel part supports PCIe Gen 4 with 20 lanes, whereas the AMD part supports PCIe Gen 3 with 60 lanes. For a mobile or compact system where power efficiency and integrated graphics are priorities, the i7-11700B could be the more suitable part, but the benchmark data shows it is slower in every measured test. The Threadripper’s active production status and unlocked multiplier also give it a longer-term position in the desktop market, while the Intel part is end-of-life and locked.
