AMD Ryzen 5 4680U vs Intel Core i5-1155G7 Comparison

The Intel Core i5-1155G7 and AMD Ryzen 5 4680U are both mobile processors aimed at thin-and-light laptops, but they represent different design philosophies. The database records an average benchmark score of 2496 for the Intel part, placing it in the 49th percentile of all CPUs. The AMD part averages 2424, sitting in the 48th percentile. Their head-to-head results show a clear split between older and newer Cinebench versions, which dictates where each processor excels.

The Verdict

The AMD Ryzen 5 4680U wins three of the four recorded head-to-head tests, taking Cinebench R15 multi-core, R15 single-core, and R23 single-core. The Intel Core i5-1155G7 wins only the R23 multi-core test, but it does so by a substantial 15.3% margin. For users running modern multi-threaded workloads like current rendering engines, the Intel part is the better pick. For legacy applications or tasks that favor the older R15 benchmark, the AMD part holds a commanding lead. The AMD also offers a lower 15W TDP against Intel's 28W, making it the efficiency choice. The Intel is still in active production, while the AMD is end-of-life. The Intel carries a launch MSRP of $309, while the AMD has no recorded launch MSRP. The 49th percentile for Intel and 48th for AMD place them within a single percentile of each other, indicating that the average user will see similar overall performance despite the divergent benchmark results.

Architecture Differences

The two chips are built on different nodes and foundries. Intel uses a 10 nm process from its own foundry, while AMD uses a 7 nm process from TSMC. The Intel die measures 144 mm², and the AMD die measures 156 mm². AMD packs 9,800 million transistors into that die, a figure not recorded for Intel. The core layouts differ significantly: Intel provides 4 cores and 8 threads, while AMD provides 6 cores and 12 threads. Cache hierarchies also diverge. Intel allocates 80 KB of L1 and 1.25 MB of L2 per core, while AMD allocates 64 KB of L1 and 512 KB of L2 per core. Both share 8 MB of L3 cache. Memory support differs, with Intel supporting DDR4 and LPDDR4X, while AMD supports LPDDR4. The AMD has a recorded memory bandwidth of 34.1 GB/s, while Intel does not have a listed bandwidth. PCIe connectivity favors Intel, which offers Gen 4 with 16 lanes, while AMD offers Gen 3. Integrated graphics are the Iris Xe-LP G7 80EU on Intel and Radeon Graphics 448SP on AMD. Sockets are Intel BGA 1449 and AMD Socket FP6.

Head-to-Head Benchmarks

The recorded head-to-head data shows a stark contrast between Cinebench R15 and R23. In R15 multi-core, the AMD scores 1291 against Intel's 822, a 36.3% deficit for Intel. In R15 single-core, the AMD scores 170 against Intel's 115, a 32.4% deficit. The R23 results flip the multi-core narrative. Intel scores 8155 against AMD's 7073, a 15.3% lead for Intel. In R23 single-core, the AMD edges out Intel with 1163 against 1151, a 1% difference. This shift suggests the Intel architecture scales better with the newer R23 workload, despite having fewer cores. The database also records Intel scores in Cinebench R20 and Geekbench, with 3425 and 4246 in multi-core, and 483 and 1574 in single-core, respectively, though AMD has no corresponding entries in those tests. Looking at overall averages, Intel's 2496 places it 0.1% ahead of the Intel Core i5-9500T, while AMD's 2424 is exactly level with the Intel Core i5-8500B. Intel's nearest rivals also include the Xeon E5-2630 v3 at 2507, a 0.4% gap, and the Xeon E5-2643 v3 at 2511, a 0.6% gap. AMD's nearest rivals include the Core i7-9850HE at 2421, a 0.1% gap, and the Ryzen 3 PRO 4450U at 2413, a 0.5% gap.

Where Each One Wins

The AMD Ryzen 5 4680U wins in Cinebench R15 multi-core and single-core, and in R23 single-core. This makes it the stronger choice for legacy multi-threaded applications and for single-threaded tasks where the 1% margin in R23 SC is negligible. The Intel Core i5-1155G7 wins in R23 multi-core, indicating a stronger showing in modern multi-threaded workloads. The AMD's lower TDP of 15W versus Intel's 28W makes it more suitable for fanless or ultra-portable designs. The Intel's higher boost clock of 4.50 GHz against AMD's 4.00 GHz, combined with PCIe Gen 4 support, gives it an edge in peak single-thread burst performance and modern storage or GPU connectivity. The Intel is also the only one of the two still in active production, which may matter for long-term availability.
