AMD Ryzen 7 4800HS vs Intel Core i5-1155G7 Comparison

Head-to-Head Benchmarks

The benchmark database pits the AMD Ryzen 7 4800HS against the Intel Core i5-1155G7 across four recorded tests, and the results paint a clear picture of two very different design philosophies. The AMD part wins three of the four head-to-head comparisons, and it does so by substantial margins in most cases.

The most lopsided result comes in the Cinebench R15 multi-core test. Here, the Ryzen 7 4800HS scores 1700.5 points against the Core i5-1155G7's 822 points. That is a 106.9% advantage for the AMD processor, meaning it more than doubles the Intel part's output in this heavily threaded workload. This is not a subtle difference; it is a generational-style gap in raw multi-threaded throughput.

The Geekbench multi-core test tells a similar story, though with a slightly smaller margin. The Ryzen 7 4800HS posts 7019 points versus 4246 points for the Intel Core i5-1155G7, a 65.3% lead. The pattern here is consistent: when all cores are engaged, the AMD chip's additional physical cores and threads translate into a commanding advantage.

Single-core results are where the narrative shifts, but only partially. In Cinebench R15 single-core, the Ryzen 7 4800HS still wins, scoring 186.5 against the Intel part's 115, a 62.2% margin. This is notable because single-core performance is typically where Intel's higher clock speeds shine. However, the Geekbench single-core test flips the script. Here, the Core i5-1155G7 takes the win with 1574 points versus 1320 points for the AMD chip, a 16.1% difference in Intel's favor.

The aggregate benchmark score confirms the overall hierarchy. The Ryzen 7 4800HS averages 2557 points across its recorded benchmarks, while the Core i5-1155G7 averages 2496 points. Both processors sit at the 49th percentile among all CPUs in the database, placing them in the same general performance tier despite their different core configurations.

Looking at the nearest rivals in the database provides additional context. The Ryzen 7 4800HS sits within 0.3% of the Intel Xeon E5-4640 v3's average score of 2550, and it is 0.5% ahead of the Xeon E5-1650 v3. The Intel Core i5-1155G7, meanwhile, is effectively tied with the Core i5-9500T at 2493 points, just 0.1% apart. Both chips are clustered in a dense performance band, but the AMD part sits at the upper edge of that band.

Architecture Differences

The architectural gap between these two mobile processors is substantial, and it explains the benchmark results better than any single specification. The AMD Ryzen 7 4800HS is built on TSMC's 7 nm process node, while the Intel Core i5-1155G7 uses Intel's 10 nm process. This process advantage gives AMD a significant efficiency and density edge, though Intel's architecture makes different tradeoffs.

The core counts diverge sharply. The Ryzen 7 4800HS packs 8 cores and 16 threads, while the Core i5-1155G7 offers 4 cores and 8 threads. This is the single most important factor in the multi-core benchmark results. The AMD part uses the Zen 2 architecture under the Renoir codename, while Intel employs the Willow Cove architecture within its Tiger Lake-U family. These are different generations of design philosophy, and the data reflects that.

Cache hierarchies also differ in structure. The AMD chip allocates 64 KB of L1 cache per core and 512 KB of L2 per core, with 8 MB of shared L3. The Intel part uses 80 KB of L1 per core and a much larger 1.25 MB of L2 per core, also with 8 MB of shared L3. The larger per-core L2 on the Intel side suggests an attempt to compensate for other architectural differences, but the shared L3 is identical at 8 MB.

Clock speeds tell a complementary story. The Ryzen 7 4800HS has a base clock of 2.90 GHz and a boost clock of 4.20 GHz. The Core i5-1155G7 starts lower at 2.50 GHz base but boosts higher to 4.50 GHz. This higher boost clock on the Intel part likely explains its Geekbench single-core victory, as that test rewards peak frequency more than sustained throughput.

Power envelopes differ as well. The AMD processor carries a 45 watt TDP, while the Intel chip is rated at 28 watts. This means the Ryzen 7 4800HS has more thermal headroom to sustain its core count, while the Core i5-1155G7 is designed for more power-constrained environments. The socket types reflect their different platforms: AMD Socket FP6 for the Ryzen, Intel BGA 1449 for the Core i5.

Memory support and I/O also distinguish the two. Both support dual-channel DDR4, but the AMD chip also supports LPDDR4, while Intel adds LPDDR4X to its list. The Ryzen 7 4800HS has a recorded memory bandwidth of 51.2 GB/s, while the Intel part's bandwidth is not recorded in the database. PCIe support differs: the AMD chip uses Gen 3, while the Intel part supports Gen 4 with 16 lanes for the CPU.

Integrated graphics present another contrast. The AMD processor includes Radeon Graphics with 448 shader processors, while Intel pairs the Core i5-1155G7 with Iris Xe-LP Graphics G7 featuring 80 execution units. The Intel solution is generally considered more capable for graphics tasks, though the database does not include iGPU benchmarks to quantify this.

The Verdict

The data supports a straightforward conclusion based on workload type. The AMD Ryzen 7 4800HS is the clear choice for multi-threaded applications. Its 106.9% lead in Cinebench R15 multi-core and 65.3% lead in Geekbench multi-core are decisive, and these are the tests that matter for rendering, compilation, and heavily parallel workloads. The 8-core, 16-thread configuration simply overwhelms the 4-core, 8-thread Intel part in these scenarios.

The Intel Core i5-1155G7 has one specific strength: Geekbench single-core performance. Its 16.1% advantage there indicates better peak frequency behavior, which can benefit lightly threaded applications and certain gaming scenarios. However, the Ryzen 7 4800HS still wins the Cinebench R15 single-core test by 62.2%, so the Intel advantage is not universal across single-threaded benchmarks.

For users who prioritize multi-core throughput, the Ryzen 7 4800HS is the obvious pick from the recorded data. For those who value the highest possible single-core score and operate within a 28 watt power envelope, the Core i5-1155G7 has its place. The 45 watt TDP of the AMD part versus 28 watts for the Intel chip also matters for system design: the Intel part fits in slimmer, cooler chassis, while the AMD part requires more robust cooling.

The average benchmark scores are close, 2557 versus 2496, but the distribution of performance is what separates them. The Ryzen 7 4800HS offers consistent multi-core dominance, while the Core i5-1155G7 offers a single-core edge in one test. Buyers should match the processor to their primary workload, as the data does not support a universal winner.
