AMD EPYC 7351P vs Intel Core i7-11700B Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep in the head-to-head benchmark suite, with the AMD EPYC 7351P winning all six comparisons against the Intel Core i7-11700B. The margin is remarkably consistent across every test, with the EPYC 7351P holding a 22.2% advantage in each of the Cinebench R15, R20, and R23 workloads, both single-core and multi-core variants.

In Cinebench R15 multi-core, the EPYC 7351P scores 2231 against 1826 for the Intel part, a 22.2% lead. The single-core result follows the same pattern: 314 versus 257, again a 22.2% delta. This uniformity across workloads is notable. It suggests the performance gap is not workload-dependent but rather a consistent architectural edge.

Moving to Cinebench R20, the EPYC 7351P posts 9296 in multi-core, compared to 7609 for the i7-11700B. The single-core test shows 1312 versus 1074. Both results again reflect the same 22.2% difference. The Cinebench R23 results continue the trend: 22135 against 18119 in multi-core, and 3125 against 2558 in single-core.

The data indicates the AMD part's advantage is not limited to heavily threaded workloads. Its single-core wins are equally decisive, which is noteworthy given the Intel part's higher boost clock. The EPYC 7351P has a boost clock of 2.90 GHz, while the i7-11700B boosts to 4.80 GHz. Despite that 1.90 GHz difference in favor of Intel, the AMD chip still wins every single-core test by the same 22.2% margin. This points to a fundamental difference in per-clock efficiency, not just raw frequency.

The average benchmark score for the EPYC 7351P is 5469, while the i7-11700B averages 5241. That is a 4.3% difference in the overall average, though the head-to-head tests show a much larger gap. The discrepancy arises because the EPYC 7351P's average includes Geekbench results (4607 multi-core, 733 single-core), which are not part of the head-to-head comparison. The Intel part lacks Geekbench entries in the database.

Looking at the nearest rivals for each part provides context. The EPYC 7351P sits within 0.5% of the Intel Xeon W-1290P (5443 average) and 0.8% of the AMD Ryzen Threadripper 1920 (5425). It trails the Intel Core i9-10900X by 1.5% and the Intel Celeron G6900 by 1.7%. The i7-11700B is essentially tied with the Intel Core i9-10850K (5240, 0% delta) and the Intel Core i5-14401E (5253, -0.2%). It also sits within 0.3% of the Intel Xeon E5-2699A v4 and 0.6% ahead of the Intel Core i5-13400T.

The percentile rankings place both parts close together: the EPYC 7351P is at the 61st percentile of all CPUs, while the i7-11700B is at the 60th. Despite the EPYC's clean sweep in direct comparisons, the broader database positions them nearly identically. This is because the EPYC's weaker Geekbench scores drag its overall standing, while the Intel part's absence of Geekbench data means its average is computed purely from its stronger Cinebench results.

The Verdict

From the recorded measurements, the AMD EPYC 7351P is the clear winner in every direct benchmark comparison. It outperforms the Intel Core i7-11700B by 22.2% across all six Cinebench tests, covering both single-threaded and multi-threaded workloads. The consistency of this margin makes the result easy to interpret: the EPYC 7351P is simply faster in these rendering workloads.

However, the intended usage contexts differ sharply. The EPYC 7351P is a server and workstation part, built for AMD Socket SP3 with a 170 W TDP and eight-channel DDR4 memory support. The i7-11700B is a mobile processor on Intel BGA 1787, with a 65 W TDP and dual-channel memory. These are not competing in the same physical or thermal envelope. The EPYC's 170 W TDP versus the Intel's 65 W TDP explains part of the performance gap, but the single-core results show the AMD architecture is also more efficient per clock.

Who should choose which? From the data, the EPYC 7351P is the pick for anyone running Cinebench-class workloads where the 22.2% advantage translates directly into reduced render times. Its 16 cores and 32 threads, combined with 64 MB of shared L3 cache, position it for multi-threaded server tasks. The i7-11700B, with 8 cores and 16 threads, is a mobile chip for systems where the 65 W TDP and integrated UHD Graphics (Xe-LP) matter more than raw benchmark scores. The Intel part is end-of-life per the database, while the EPYC remains active in production.

The database shows the EPYC 7351P at the 61st percentile versus the i7-11700B's 60th. That near-parity in percentile, despite the head-to-head sweep, means the Intel part is not a poor performer overall. It is competitive with mainstream desktop chips like the Core i9-10850K. But in direct comparison, the AMD server chip wins every measured test.

Architecture Differences

The two processors come from different design philosophies and manufacturing nodes. The AMD EPYC 7351P uses the Zen architecture on the Naples codename, built on a 14 nm process at GlobalFoundries. It packs 4,800 million transistors into a 213 mm² die. The Intel Core i7-11700B uses the Tiger Lake architecture (Tiger Lake-H codename) on Intel's 10 nm process, with a 190 mm² die size. The database does not list a transistor count for the Intel part.

Core counts differ substantially. The EPYC 7351P offers 16 cores and 32 threads, while the i7-11700B provides 8 cores and 16 threads. Base clocks are 2.40 GHz for the AMD and 3.20 GHz for the Intel. Boost clocks are 2.90 GHz and 4.80 GHz respectively. The Intel part has the higher clocks, yet the AMD part wins all benchmarks, indicating the Zen cores deliver more work per clock cycle in these tests.

Cache hierarchies are also distinct. The EPYC 7351P has 96 KB of L1 cache per core, 512 KB of L2 per core, and a large 64 MB shared L3 cache. The i7-11700B has 80 KB of L1 per core, a larger 1.25 MB of L2 per core, but only 24 MB of shared L3. The AMD part's 64 MB L3 is a significant advantage for workloads that benefit from a large shared cache pool.

Memory subsystems differ by design intent. The EPYC 7351P supports eight-channel DDR4 memory with a peak bandwidth of 170.6 GB/s. The i7-11700B supports dual-channel DDR4 with 51.2 GB/s bandwidth. This is a 3.3x difference in theoretical memory bandwidth, which matters for server workloads. The AMD part also supports ECC memory, while the Intel part does not. PCIe support also differs: the EPYC uses Gen 3, while the i7-11700B supports Gen 4 with 20 CPU-only lanes.

The Intel part includes integrated graphics (UHD Graphics, Xe-LP architecture), while the EPYC 7351P has no integrated graphics in the database. The AMD part has an unlocked multiplier, whereas the Intel part is locked. The EPYC is also a server/workstation product on Socket SP3, while the Intel is a mobile chip on BGA 1787.

Process nodes differ: 14 nm for the AMD versus 10 nm for the Intel. The smaller Intel node did not translate into a performance win in the recorded benchmarks. The EPYC's larger die (213 mm² versus 190 mm²) and higher transistor count (4,800 million versus not listed) reflect its more complex server-oriented design.

Where Each One Wins

The AMD EPYC 7351P wins in every benchmark category recorded in the database. Its six head-to-head victories cover Cinebench R15, R20, and R23, each in both single-core and multi-core variants. The 22.2% margin is uniform across all six tests. For server or workstation workloads that rely on Cinebench-class rendering, the EPYC 7351P is the stronger choice. Its 16 cores, 32 threads, and 64 MB of L3 cache support heavy multi-threaded loads. The eight-channel memory interface with 170.6 GB/s bandwidth suits memory-intensive server applications. The ECC memory support adds reliability for data-center use cases.

The Intel Core i7-11700B does not win any head-to-head benchmark in the database. Its advantages lie outside the measured scores. It draws significantly less power, with a 65 W TDP versus the EPYC's 170 W. It includes integrated UHD Graphics, which the EPYC lacks entirely. Its dual-channel memory and 51.2 GB/s bandwidth are lower, but appropriate for a mobile platform. The 10 nm process node and BGA 1787 socket target compact, power-constrained systems. The i7-11700B is also end-of-life, while the EPYC remains active.

For users comparing these two, the decision rests on workload and platform. The EPYC 7351P is a server/workstation processor for socket SP3 motherboards with eight-channel memory support. The i7-11700B is a mobile processor soldered to BGA 1787 boards. The benchmark data gives no scenario where the Intel part wins a performance test. Its value is in its lower power envelope, integrated graphics, and mobile form factor. The EPYC 7351P is the performance pick in every measured metric, but it demands a server-class platform with appropriate cooling and power delivery. The Intel part is the choice for embedded or mobile systems where the 65 W TDP and integrated graphics are prerequisites, accepting the 22.2% performance deficit in Cinebench workloads.
