AMD Ryzen Threadripper 1920 vs Intel Core i7-11700B Comparison

The AMD Ryzen Threadripper 1920 and Intel Core i7-11700B occupy different corners of the processor market, yet the database places them close enough in average score to invite direct comparison. The Threadripper is a 12-core desktop part built on AMD's Zen architecture, while the Core i7-11700B is an 8-core mobile chip from Intel's Tiger Lake-H family. The recorded Cinebench results show a consistent, narrow advantage for the AMD processor across every test in the comparison set.

Where Each One Wins

The head-to-head data is unambiguous: the AMD Ryzen Threadripper 1920 wins all six recorded Cinebench tests. The Intel Core i7-11700B does not win a single benchmark in the comparison. The margins are small, ranging from 3.4% to 3.5%, but they are uniform. This means the Threadripper is not merely faster in one workload class; it holds the lead in both multi-threaded and single-threaded rendering tests.

For multi-threaded workloads, the Threadripper's 12 cores and 24 threads provide a structural advantage over the Intel chip's 8 cores and 16 threads. In Cinebench R23 multi-core, the AMD part scores 18,756 against 18,119 for the Intel part, a 3.5% lead. The R20 multi-core test shows 7,877 versus 7,609, also 3.5%. The R15 multi-core test shows 1,890 versus 1,826, again 3.5%.

For single-threaded workloads, the Intel chip's higher boost clock of 4.80 GHz versus 3.80 GHz might suggest an advantage, but the data contradicts that expectation. The Threadripper leads in every single-core test: 266 versus 257 in R15, 1,111 versus 1,074 in R20, and 2,647 versus 2,558 in R23. The single-core margins are 3.5%, 3.4%, and 3.5% respectively.

The use-case split is therefore simple. Users running Cinebench-style rendering workloads, whether multi-threaded or single-threaded, will see better scores on the Threadripper. The Intel part is not without merit in other dimensions, but within this benchmark suite it trails across the board.

Architecture Differences

The two processors come from different architectural lineages with distinct design priorities. The AMD Ryzen Threadripper 1920 uses the Zen architecture, specifically the Whitehaven generation, built on a 14 nm process at GlobalFoundries. It contains 9,600 million transistors across a dual-die design with each die measuring 213 mm². The Intel Core i7-11700B uses the Tiger Lake-H architecture on Intel's 10 nm process, with a single die of 190 mm².

Core counts differ substantially. The Threadripper has 12 cores and 24 threads, while the Core i7-11700B has 8 cores and 16 threads. That is a 50% core advantage for the AMD part, which explains its multi-threaded lead despite the Intel chip's higher boost clock.

Cache configurations also differ. The Threadripper has 96 KB of L1 cache per core, 512 KB of L2 per core, and 32 MB of L3 cache. The Intel chip has 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3. The Intel part has more L2 per core, but the AMD part has more total L3.

Memory support is another differentiator. Both support DDR4, but the Threadripper uses a quad-channel memory bus with 85.3 GB/s of bandwidth, while the Core i7-11700B uses a dual-channel bus with 51.2 GB/s. The AMD part has substantially more memory bandwidth available, which can matter in memory-intensive workloads.

PCIe connectivity differs as well. The Threadripper offers PCIe Gen 3 with 60 lanes from the CPU, while the Intel chip offers PCIe Gen 4 with 20 lanes. The Intel part has a newer PCIe generation but far fewer lanes.

The Threadripper has no integrated graphics, while the Core i7-11700B includes UHD Graphics based on Xe-LP. The Intel chip is also a mobile-market part with a BGA 1787 socket, whereas the Threadripper is a desktop part on Socket SP3r2.

The Threadripper has an unlocked multiplier, while the Intel chip is locked. The Intel part was released on May 10, 2021, while the Threadripper's release date is not recorded in the database. Both are end-of-life products.

Head-to-Head Benchmarks

The database records six Cinebench comparisons between these two processors. The AMD Ryzen Threadripper 1920 wins all six. The margins are consistent, which suggests a stable performance relationship rather than test-specific noise.

In Cinebench R15 multi-core, the Threadripper scores 1,890 against 1,826 for the Intel chip, a 3.5% lead. In R15 single-core, the Threadripper scores 266 against 257, also 3.5%.

In Cinebench R20 multi-core, the Threadripper scores 7,877 against 7,609, a 3.5% lead. In R20 single-core, the scores are 1,111 versus 1,074, a 3.4% lead. This is the smallest margin in the set, though still a win for the AMD part.

In Cinebench R23 multi-core, the Threadripper scores 18,756 against 18,119, a 3.5% lead. In R23 single-core, the scores are 2,647 versus 2,558, again 3.5%.

The consistency of the 3.5% margin across five of the six tests is notable. The only exception is R20 single-core at 3.4%. This uniformity suggests the Threadripper's advantage is structural rather than workload-specific.

Looking at the broader database context, the Threadripper 1920 has an average benchmark score of 5,425, placing it at the 60th percentile of all CPUs. Its nearest rivals include the Intel Xeon W-1290P at 5,443 (0.3% behind), the AMD EPYC 7351P at 5,469 (0.8% behind), the Intel Core i9-13900TE at 5,342 (1.5% ahead), and the Intel Core i9-10900KF at 5,316 (2.1% ahead).

The Core i7-11700B has an average benchmark score of 5,241, also at the 60th percentile. Its nearest rivals include the Intel Core i9-10850K at 5,240 (essentially tied), the Intel Core i5-14401E at 5,253 (0.2% behind), the Intel Xeon E5-2699A v4 at 5,259 (0.3% behind), and the Intel Core i5-13400T at 5,210 (0.6% ahead).

The average score difference between the two processors is 5,425 versus 5,241, a gap of about 3.5%, which aligns with the head-to-head margins.

The Verdict

The data points to a clear, if narrow, winner. The AMD Ryzen Threadripper 1920 outperforms the Intel Core i7-11700B in every recorded Cinebench test, with margins of 3.4% to 3.5%. The Threadripper's 12 cores and 24 threads give it a structural advantage in multi-threaded workloads, while its single-core performance is also slightly ahead despite the Intel chip's higher boost clock.

The Threadripper also offers substantially more memory bandwidth (85.3 GB/s versus 51.2 GB/s) and more PCIe lanes (60 versus 20), which matters for systems with many expansion cards or high-bandwidth peripherals. The Intel chip counters with a newer PCIe generation (Gen 4 versus Gen 3), integrated graphics, and a much lower TDP of 65 W versus 140 W.

For users building a desktop workstation with heavy multi-threaded rendering workloads, the Threadripper 1920 is the better choice based on the recorded data. For users who need integrated graphics, a lower power envelope, or a mobile form factor, the Core i7-11700B has clear advantages, though it trails in raw Cinebench performance.

The average benchmark scores reinforce this: 5,425 for the Threadripper versus 5,241 for the Core i7-11700B. Both sit at the 60th percentile of all CPUs, but the AMD part holds a consistent edge in the database's measurements.
