Architecture Differences

The two processors come from different manufacturers, process nodes, and architectural lineages. The Intel Core i7-1185GRE uses the Tiger Lake-U architecture with Willow Cove cores, built on Intel's 10 nm process. The AMD Ryzen 5 7520C uses the Zen 2 architecture under the Mendocino codename, built on TSMC's 6 nm process. This process difference is notable: the AMD chip uses a smaller node, while the Intel chip uses a larger node but a different core design.

Core counts are identical: both have 4 cores and 8 threads. The base clock differs, with the Intel running at 1800 MHz and the AMD at 2800 MHz. The boost clock is closer: 4.40 GHz for the Intel and 4.30 GHz for the AMD. The AMD chip starts at a higher base frequency but has a slightly lower boost ceiling.

Cache hierarchies diverge significantly. The Intel Core i7-1185GRE has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 12 MB of shared L3 cache. The AMD Ryzen 5 7520C has 64 KB of L1 per core, 512 KB of L2 per core, and only 4 MB of shared L3 cache. That is a threefold difference in L3 capacity: 12 MB versus 4 MB.

Memory support differs. The Intel chip supports DDR4 and LPDDR4X, while the AMD chip supports LPDDR5. Both use a dual-channel memory bus, but the AMD chip has a recorded memory bandwidth of 88.0 GB/s; the Intel chip has no bandwidth figure recorded. ECC memory is supported on the Intel chip but not on the AMD chip.

PCI Express generation also differs: the Intel Core i7-1185GRE supports Gen 4 with 4 CPU-only lanes, while the AMD Ryzen 5 7520C supports Gen 3 with 4 CPU-only lanes.

Integrated graphics are different: the Intel chip has Iris Xe-LP Graphics G7 with 96 execution units, while the AMD chip has Radeon 610M graphics.

Sockets are not interchangeable: Intel uses BGA 1449, and AMD uses Socket FT6.

Head-to-Head Benchmarks

The recorded benchmark data shows a consistent pattern: the AMD Ryzen 5 7520C outperforms the Intel Core i7-1185GRE in every single head-to-head test. This is a clean sweep, with the AMD chip winning all six recorded comparisons.

Starting with Cinebench R15, the AMD chip scores 741 in multi-core versus Intel's 668, a delta of -9.9%. In single-core R15, the AMD scores 104 versus Intel's 94, a delta of -9.6%. Both margins are close to ten percent.

Moving to Cinebench R20, the AMD chip scores 3089 in multi-core versus Intel's 2786, a delta of -9.8%. In single-core R20, the AMD scores 435 versus Intel's 393, a delta of -9.7%.

In Cinebench R23, the AMD chip scores 7355 in multi-core versus Intel's 6635, a delta of -9.8%. In single-core R23, the AMD scores 1038 versus Intel's 936, a delta of -9.8%.

The consistency is striking. Every test shows the AMD chip ahead by roughly 9.6% to 9.9%. The margins are nearly identical across all six tests, suggesting a uniform performance advantage rather than a workload-specific one. The Intel chip's higher boost clock of 4.40 GHz does not translate into a win in any test, despite being 100 MHz higher than the AMD's 4.30 GHz boost.

The Geekbench results are only recorded for the Intel chip, not the AMD chip, so they cannot be compared directly. The Intel Core i7-1185GRE scores 4060 in Geekbench multi-core and 1848 in single-core, but no corresponding AMD scores exist in the database for a head-to-head comparison.

The rival data provides context. The Intel Core i7-1185GRE sits within 0.2% of the AMD Ryzen 5 3409GE and Intel Core i5-1145G7E, and within 1% of the Intel Core i7-5950HQ. The AMD Ryzen 5 7520C sits within 0.2% of the Intel Core i7-1160G7, within 0.3% of the Intel Atom C5125, and within 0.4% of the AMD Ryzen 3 5300U and Intel Core i5-9400T. Both chips are closely clustered with their nearest rivals, but the AMD chip is faster in direct comparison.

The Verdict

The data is unambiguous. The AMD Ryzen 5 7520C is the faster processor in every recorded benchmark comparison. Across Cinebench R15, R20, and R23, in both single-core and multi-core tests, the AMD chip leads by margins between 9.6% and 9.9%. The Intel Core i7-1185GRE does not win a single head-to-head test.

The Intel chip does have strengths in non-benchmark areas: a larger L3 cache (12 MB versus 4 MB), ECC memory support, PCIe Gen 4 support, and a higher boost clock (4.40 GHz versus 4.30 GHz). But none of those features translate into a performance win in the recorded data.

The average benchmark scores tell a slightly different story at the aggregate level. The Intel Core i7-1185GRE has a higher average score (2178 versus 2127) and a higher percentile ranking (47th versus 46th). This is because the Intel chip has additional Geekbench scores in the database that are not available for the AMD chip, and those scores pull its average upward.

Buyers who prioritize raw CPU performance in Cinebench workloads should choose the AMD Ryzen 5 7520C. Buyers who need ECC memory support, PCIe Gen 4, or a larger L3 cache should choose the Intel Core i7-1185GRE. The Intel chip also has a recorded launch MSRP of $490, while the AMD chip has no recorded launch MSRP.

Where Each One Wins

AMD Ryzen 5 7520C wins in all recorded CPU benchmark tests. The head-to-head data shows six wins out of six for the AMD chip. Every Cinebench test, from R15 to R23, in both single-core and multi-core modes, favors the AMD Ryzen 5 7520C. The margins are consistent at approximately 9.6% to 9.9%. This makes the AMD chip the clear choice for workloads measured by Cinebench, which typically reflect general CPU rendering and compute performance.

Intel Core i7-1185GRE wins in platform features. The Intel chip supports ECC memory, which the AMD chip does not. The Intel chip has PCIe Gen 4 support, while the AMD chip only has Gen 3. The Intel chip has a larger L3 cache (12 MB versus 4 MB) and a higher boost clock (4.40 GHz versus 4.30 GHz). The Intel chip also has a higher average benchmark score (2178 versus 2127) and a higher percentile rank (47th versus 46th), though this is partly because Geekbench scores exist for the Intel chip but not the AMD chip in the database.

AMD Ryzen 5 7520C wins in process technology and memory bandwidth. The AMD chip is built on a smaller 6 nm process at TSMC, has a smaller die (100 mm² versus 144 mm²), and supports faster LPDDR5 memory with a recorded bandwidth of 88.0 GB/s. The Intel chip uses a 10 nm process and supports DDR4/LPDDR4X with no bandwidth figure recorded.

Intel Core i7-1185GRE wins in release timing and pricing data. The Intel chip was released in September 2020 and has a recorded launch MSRP of $490. The AMD chip was released in May 2023 and has no launch MSRP recorded.

For applications that are heavily threaded and measured by Cinebench, the AMD Ryzen 5 7520C is the better choice. For systems requiring ECC memory, PCIe Gen 4 connectivity, or maximum L3 cache capacity, the Intel Core i7-1185GRE is the better choice despite its lower benchmark scores in the head-to-head comparison.
