AMD EPYC 7452 vs Intel Core i7-1185G7 Comparison

The Verdict

The recorded data presents a decisive outcome: the AMD EPYC 7452 wins every single head-to-head benchmark in the database, taking all six comparisons. The Intel Core i7-1185G7 does not record a single victory in any tested workload. For users seeking maximum multi-threaded throughput, the EPYC 7452 is the clear choice, delivering scores that are roughly four to five times higher than the Intel part across all Cinebench tests. The Intel Core i7-1185G7, despite being a mobile processor with a higher boost clock, cannot match the EPYC 7452's raw computational output in any measured category.

The EPYC 7452 sits at the 66th percentile of all CPUs in the database, while the Core i7-1185G7 sits at the 67th percentile. These near-identical percentile rankings are misleading given the massive benchmark gaps; the EPYC's average benchmark score of 11279 is actually lower than the Intel's 11697, yet the EPYC dominates in every head-to-head test. This discrepancy reflects that the average benchmark score includes a broader set of workloads where the Intel part's strengths in single-threaded and mobile-specific tasks balance out the EPYC's huge multicore advantage.

For a mobile workstation user needing portability and integrated graphics, the Core i7-1185G7 is the only option with a built-in GPU, as the EPYC 7452 has no integrated graphics at all. However, for server or workstation deployment where core count and memory bandwidth matter most, the EPYC 7452 is the unambiguous winner. The data shows no scenario in the head-to-head results where the Intel chip outperforms the AMD chip, making the EPYC 7452 the superior choice for any workload represented in these benchmarks.

Architecture Differences

The architectural divide between these two processors is substantial. The Intel Core i7-1185G7 uses the Tiger Lake architecture, specifically the Tiger Lake-U codename, built on a 10 nm process node at Intel's foundry. It features 4 cores and 8 threads, with a base clock of 3.00 GHz and a boost clock of 4.80 GHz. The chip has a die size of 144 mm² and includes 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 12 MB of shared L3 cache. This is a mobile processor with a 28 W TDP, designed for thin-and-light laptops, and it integrates Iris Xe-LP Graphics G7 96EU.

The AMD EPYC 7452 belongs to the EPYC 7002 series, using the Zen 2 architecture with the Rome codename. It is built on a 7 nm process at TSMC, featuring 32 cores and 64 threads. Its base clock is 2.20 GHz with a boost clock of 3.35 GHz, and it has a TDP of 155 W, reflecting its server-class design. The EPYC 7452 contains 3,800 million transistors on a 74 mm² die, with 96 KB of L1 cache per core, 512 KB of L2 cache per core, and a massive 128 MB of shared L3 cache. It supports eight-channel DDR4 memory with a bandwidth of 204.8 GB/s, while the Intel chip supports dual-channel DDR4 and LPDDR4X memory without a listed bandwidth figure.

The manufacturing process differences are notable: Intel's 10 nm process versus TSMC's 7 nm process. The EPYC's smaller die size of 74 mm² compared to Intel's 144 mm², despite having eight times the cores, highlights the efficiency of the Zen 2 architecture. The Intel chip uses the BGA 1449 socket, while the EPYC uses the SP3 socket. The Intel chip supports PCIe Gen 4 with 4 lanes from the CPU, while the EPYC supports PCIe Gen 4 without a lane count specified. ECC memory is supported on the EPYC 7452 but not on the Intel Core i7-1185G7. The Intel chip is marked as end-of-life production status, while the EPYC remains active.

Head-to-Head Benchmarks

The database records six head-to-head benchmark comparisons, all won by the AMD EPYC 7452. In Cinebench R15 multicore, the EPYC scores 3930 against the Intel's 848, a delta of -78.4% for the Intel chip. The EPYC is approximately 4.6 times faster. In Cinebench R15 singlecore, the EPYC scores 554 against 119, a delta of -78.5%, making the EPYC roughly 4.7 times faster.

Cinebench R20 multicore shows the EPYC at 16377 versus the Intel at 3534, delta of -78.4%, a 4.6 times advantage. Cinebench R20 singlecore shows 2312 versus 498, delta of -78.5%, a 4.6 times advantage. Cinebench R23 multicore shows 38993 versus 8416, delta of -78.4%, a 4.6 times advantage. Cinebench R23 singlecore shows 5505 versus 1188, delta of -78.4%, a 4.6 times advantage.

The consistency of the delta percentages across all tests, ranging from -78.4% to -78.5%, indicates a uniform performance gap regardless of workload type. The EPYC's advantage holds in both multicore and singlecore tests, which is remarkable given the Intel chip's higher boost clock of 4.80 GHz versus 3.35 GHz. The EPYC's larger cache hierarchy and greater core count overcome the clock speed disadvantage in every measured test.

The Intel Core i7-1185G7 does have additional benchmark scores not included in the head-to-head comparison, such as Geekbench multicore at 4816, Passmark multithread at 10115, and Passmark single thread at 2778. These scores contribute to its average benchmark score of 11697, which exceeds the EPYC's average of 11279. However, in the six directly comparable tests, the EPYC wins all of them by significant margins.

Where Each One Wins

Based strictly on the recorded head-to-head data, the AMD EPYC 7452 wins in every benchmark category tested. It is the superior choice for Cinebench R15, R20, and R23 workloads in both singlecore and multicore configurations. This makes it the preferred processor for rendering, simulation, and any compute-intensive task that relies on the Cinebench test suite as a proxy. The EPYC's 32 cores and 64 threads, combined with 128 MB of L3 cache and eight-channel memory bandwidth of 204.8 GB/s, provide the architectural foundation for these results.

The Intel Core i7-1185G7 records zero wins in the head-to-head benchmarks. However, the broader benchmark data shows areas where the Intel chip has strengths. Its average benchmark score of 11697 is higher than the EPYC's 11279, indicating that in non-Cinebench workloads, the Intel part performs competitively. The Intel chip's Passmark single thread score of 2778 and Geekbench singlecore score of 1591 suggest capable single-threaded performance for its class. The integrated Iris Xe-LP Graphics G7 96EU makes it the only option of the two with built-in display capabilities, which is essential for mobile systems without discrete GPUs.

The use-case split is clear: the EPYC 7452 is designed for server and workstation environments where multicore throughput, ECC memory support, and high memory bandwidth are priorities. The Intel Core i7-1185G7 is a mobile processor with a 28 W TDP, suited for laptops requiring integrated graphics and lower power consumption. For any workload in the head-to-head data, the EPYC wins. For mobile deployment where the integrated GPU is necessary, the Intel chip has a functional advantage that the EPYC cannot offer due to its lack of integrated graphics. The production status also favors the EPYC, which remains active, while the Intel chip is end-of-life.
