AMD Ryzen 7 2800H vs Intel Core i5-1145GRE Comparison

The Verdict

The benchmark data is unambiguous: the Intel Core i5-1145GRE wins every single head-to-head benchmark against the AMD Ryzen 7 2800H, taking all 6 recorded tests. The margins are narrow, ranging from 1.0% to 1.1% across Cinebench R15, R20, and R23 in both single-core and multi-core workloads. Neither chip separates itself from the pack in the broader database, as both sit at the 45th percentile among all CPUs. The Intel part edges out the AMD part in average benchmark score, 2025 versus 2002, a difference of roughly 1.1%.

For a user choosing between these two, the Intel Core i5-1145GRE is the clear pick if raw CPU performance is the only criterion. It wins in every recorded test, and its advantage is consistent rather than workload-specific. The AMD Ryzen 7 2800H, however, is not far behind, and its lower 15W TDP compared to Intel's 28W TDP suggests it may fit into thermally constrained designs where the Intel part cannot. The data does not measure power draw directly, but the TDP figures in the database indicate that AMD's chip is rated for substantially lower power consumption.

The verdict for most buyers: choose the Intel Core i5-1145GRE if you want the fastest Cinebench scores in this pairing. Choose the AMD Ryzen 7 2800H if the platform's lower TDP rating matters more than the small performance gap, since the benchmark deltas are within a percentage point or two in every test.

Where Each One Wins

The Intel Core i5-1145GRE wins in every category measured. In multi-core workloads, it leads by 1.1% in Cinebench R15 (705 vs. 697), R20 (2940 vs. 2907), and R23 (7001 vs. 6922). In single-core tests, it leads by 1.0% in R15 (99 vs. 98) and R20 (414 vs. 410), and by 1.1% in R23 (988 vs. 977). The consistency of these margins suggests the Intel part has a slight architectural edge that applies uniformly across rendering workloads, regardless of thread count.

The AMD Ryzen 7 2800H does not win a single benchmark in the head-to-head data. Its closest result is in Cinebench R15 single-core, where it scores 98 versus Intel's 99, a 1% gap. The largest gap is also just 1.1%, so the AMD part is never embarrassed, but it is never ahead either.

Where the AMD part does "win" is in the power envelope. The database lists the Ryzen 7 2800H with a TDP of 15W, whereas the Intel Core i5-1145GRE is rated at 28W. For thin-and-light laptops or passively cooled designs, that TDP difference could be decisive, even though the benchmark scores do not capture thermal behavior directly. The AMD chip also uses a larger die (246 mm²) and a 14 nm process, which may influence platform-level design choices.

Architecture Differences

The two processors come from fundamentally different design eras and philosophies. The Intel Core i5-1145GRE is built on Intel's 10 nm process and uses the Tiger Lake-U architecture with Willow Cove cores. It has 4 cores and 8 threads, with a base clock of 1.50 GHz and a boost clock of 4.10 GHz. The AMD Ryzen 7 2800H uses GlobalFoundries' 14 nm process and the Zen architecture (Raven Ridge codename), also with 4 cores and 8 threads, but with a higher base clock of 3.40 GHz and a lower boost clock of 3.80 GHz.

Cache configurations differ significantly. The Intel part has 80 KB of L1 per core, 1.25 MB of L2 per core, and 8 MB of shared L3. The AMD part has 128 KB of L1 per core, 512 KB of L2 per core, and only 4 MB of shared L3. The Intel chip's larger L3 cache likely contributes to its slight benchmark advantage, while the AMD chip's larger L1 and per-core L2 may help in other unmeasured scenarios.

Integrated graphics differ as well. Intel uses Iris Xe Graphics G7 with 80 execution units, while AMD uses Radeon RX Vega 11. The database does not provide graphics benchmarks, so no performance comparison is possible here. Memory support also differs: Intel supports DDR4 and LPDDR4X, while AMD supports only DDR4. Both use dual-channel memory buses. The Intel part supports ECC memory, while the AMD part does not. Intel's PCIe implementation is Gen 4 with 4 lanes (CPU only), while the AMD part has no PCIe data listed.

The Intel chip sits in an Intel BGA 1449 socket, while AMD uses AMD Socket FP5. Both are mobile-market parts, and both are listed as Active in production. The Intel part launched in September 2020 with a launch MSRP of $362; the AMD part launched in May 2018 with no launch MSRP recorded.

FAQ

Q: Which processor is faster in multi-core workloads?

A: The Intel Core i5-1145GRE wins all three multi-core Cinebench tests: R15 (705 vs. 697), R20 (2940 vs. 2907), and R23 (7001 vs. 6922), each by 1.1%.

Q: Which processor is faster in single-core workloads?

A: The Intel Core i5-1145GRE also wins all three single-core tests: R15 (99 vs. 98), R20 (414 vs. 410), and R23 (988 vs. 977), by 1.0% to 1.1%.

Q: Do the two processors have the same number of cores and threads?

A: Yes, both have 4 cores and 8 threads. The Intel part has a 1.50 GHz base and 4.10 GHz boost; the AMD part has a 3.40 GHz base and 3.80 GHz boost.

Q: Which chip has a lower TDP?

A: The AMD Ryzen 7 2800H is rated at 15W TDP, while the Intel Core i5-1145GRE is rated at 28W TDP, a substantial difference in the database's power specifications.

Q: How do their average benchmark scores compare?

A: The Intel Core i5-1145GRE has an average benchmark score of 2025, while the AMD Ryzen 7 2800H scores 2002. Both sit at the 45th percentile among all CPUs.

Head-to-Head Benchmarks

The head-to-head data covers six Cinebench tests, and the Intel Core i5-1145GRE wins all of them. The largest margins are 1.1%, appearing in Cinebench R15 multi-core (705 vs. 697), R20 multi-core (2940 vs. 2907), R23 multi-core (7001 vs. 6922), and R23 single-core (988 vs. 977). The smallest margins are 1.0%, in R15 single-core (99 vs. 98) and R20 single-core (414 vs. 410).

The multi-core results are particularly telling because both chips have identical core and thread counts, so the Intel advantage comes from clock behavior, cache, or architecture efficiency rather than raw parallelism. Intel's boost clock is 4.10 GHz versus AMD's 3.80 GHz, which likely explains part of the single-core lead. The Intel part's 8 MB of shared L3 versus AMD's 4 MB may also help in rendering workloads that reuse data across cores.

The Cinebench R23 scores are the most modern test in the set and show the same pattern: Intel leads by 1.1% in both single-core and multi-core. The AMD part's higher base clock (3.40 GHz vs. 1.50 GHz) does not translate into a benchmark win, suggesting that sustained boost behavior and IPC differences matter more than the base clock figure.

Overall, the benchmark picture is clear: the Intel Core i5-1145GRE is the faster processor in every recorded test, but the AMD Ryzen 7 2800H remains competitive within a narrow margin. No benchmark shows a blowout, and the 45th percentile ranking for both chips places them in the same performance tier within the broader database.
