AMD Ryzen 7 4700U vs Intel Core i5-1345UE Comparison

The AMD Ryzen 7 4700U and Intel Core i5-1345UE are both 15 W mobile processors aimed at thin-and-light laptops, but they represent very different design philosophies and generations. The AMD part relies on eight full Zen 2 cores, while the Intel chip uses a hybrid Raptor Lake layout with a higher core count and a faster boost clock. Benchmark data shows a split decision: the AMD wins older Cinebench tests, while the Intel wins newer ones, making the choice highly dependent on workload.

FAQ

Q: Which processor has more cores?

A: The Intel Core i5-1345UE has 10 cores, while the AMD Ryzen 7 4700U has 8 cores. However, the AMD part has 8 threads matching its core count, whereas the Intel part has 12 threads, which is fewer than its core count due to its hybrid architecture.

Q: How do their single-core Cinebench R23 scores compare?

A: The Intel Core i5-1345UE scores 1317 in Cinebench R23 single-core, which is 7.3% higher than the AMD Ryzen 7 4700U’s score of 1220.5. This indicates a clear Intel advantage in lightly-threaded performance.

Q: Which chip has the larger L3 cache?

A: The Intel Core i5-1345UE has a 12 MB shared L3 cache, which is 50% larger than the 8 MB shared L3 cache found on the AMD Ryzen 7 4700U. This larger cache can benefit workloads that access the same data repeatedly.

Q: What is the difference in their process nodes?

A: The AMD Ryzen 7 4700U is built on a 7 nm process by TSMC, while the Intel Core i5-1345UE uses a 10 nm process from Intel. The AMD chip also integrates 9,800 million transistors on a 156 mm² die, whereas the Intel chip’s transistor count and die size are not listed.

Q: Do both processors support the same memory types?

A: No. The AMD Ryzen 7 4700U only supports DDR4 memory, while the Intel Core i5-1345UE supports both DDR4 and DDR5. Both use a dual-channel memory bus, but the AMD part has a stated memory bandwidth of 51.2 GB/s, while the Intel part does not list a bandwidth figure.

Q: Which processor has a higher boost clock?

A: The Intel Core i5-1345UE has a boost clock of 4.60 GHz, which is higher than the 4.10 GHz boost clock of the AMD Ryzen 7 4700U. The AMD part does have a higher base clock at 2000 MHz versus the Intel’s 1400 MHz.

Architecture Differences

The architectural split between these two mobile CPUs is stark. The AMD Ryzen 7 4700U is based on the Zen 2 architecture, codenamed Renoir, and is manufactured on a 7 nm process by TSMC. It packs 8 cores and 8 threads, meaning it lacks simultaneous multithreading. The chip integrates 9,800 million transistors on a 156 mm² die and uses an AMD Socket FP6. Its cache hierarchy consists of 64 KB of L1 per core, 512 KB of L2 per core, and 8 MB of shared L3 cache.

The Intel Core i5-1345UE, in contrast, uses the Raptor Lake architecture, specifically Raptor Lake-U, and is built on Intel’s 10 nm process. It features 10 cores and 12 threads, which indicates a hybrid design with performance and efficiency cores. It is mounted on Intel BGA 1744. Its cache configuration is different as well: 80 KB of L1 per core, 1.25 MB of L2 per core, and a larger 12 MB of shared L3 cache. The Intel chip also supports PCIe Gen 4 with 8 lanes for the CPU, whereas the AMD part only supports PCIe Gen 3.

Both processors integrate graphics, but they differ significantly. The AMD Ryzen 7 4700U has Radeon Graphics with 448 shader processors, while the Intel Core i5-1345UE has Iris Xe Graphics with 80 execution units. Neither chip supports ECC memory, and both have a 15 W TDP. The AMD part was released in January 2020, while the Intel part came out three years later in January 2023.

Head-to-Head Benchmarks

The head-to-head data reveals a fascinating generational shift in benchmark priorities. In Cinebench R15 multi-core, the AMD Ryzen 7 4700U scores 1094.5 against the Intel’s 940, giving AMD a decisive 16.4% win. The margin is even larger in Cinebench R15 single-core, where the AMD scores 180 versus the Intel’s 132, a 36.4% advantage. These are substantial victories for the older AMD chip.

However, the tables turn completely in Cinebench R23. In multi-core, the Intel Core i5-1345UE scores 9329, which is 20.9% higher than the AMD’s 7378. This is a massive reversal, showing the Intel chip’s newer architecture and higher core count pay off in modern multi-threaded rendering workloads. In single-core R23, the Intel also wins, scoring 1317 against the AMD’s 1220.5, a 7.3% lead.

The overall benchmark averages tell a similar story of parity. The AMD Ryzen 7 4700U has an average benchmark score of 2722, while the Intel Core i5-1345UE sits at 2698. The AMD part’s nearest rival is the Intel Xeon E5-2628L v3 with an average score of 2724, a delta of -0.1%, meaning the AMD is essentially tied with that Xeon. The Intel chip’s nearest rival is the Intel Core i7-8700T at 2701, a delta of -0.1% as well. Both CPUs sit at the 50th percentile among all CPUs, indicating they are mid-pack performers.

Specification Differences

The specification sheets for these two processors show several key differences beyond the core counts. The most obvious is the process node: the AMD uses 7 nm TSMC, while the Intel uses 10 nm Intel. The AMD chip has a base clock of 2000 MHz and a boost clock of 4.10 GHz, whereas the Intel has a lower base of 1400 MHz but a higher boost of 4.60 GHz.

Memory support is another differentiator. The AMD Ryzen 7 4700U is limited to DDR4, while the Intel Core i5-1345UE supports both DDR4 and DDR5. The AMD part lists a memory bandwidth of 51.2 GB/s, while the Intel part does not provide a bandwidth number. Both use dual-channel memory buses.

The cache structures differ in size and organization. The AMD has 64 KB L1 and 512 KB L2 per core, with 8 MB shared L3. The Intel has 80 KB L1 and 1.25 MB L2 per core, with 12 MB shared L3. This gives the Intel chip more total cache, particularly at the L3 level.

PCIe support also differs. The Intel Core i5-1345UE supports PCIe Gen 4 with 8 CPU lanes, while the AMD Ryzen 7 4700U only supports PCIe Gen 3. The integrated graphics are different as well: AMD’s Radeon Graphics with 448 shader processors versus Intel’s Iris Xe Graphics with 80 execution units. The sockets are not interchangeable, with AMD using FP6 and Intel using BGA 1744. The AMD part has a listed part number of 100-000000083, while the Intel part has none listed.

Where Each One Wins

The AMD Ryzen 7 4700U is the clear winner in older Cinebench R15 tests. It beats the Intel by 16.4% in multi-core and by a massive 36.4% in single-core. This suggests that for legacy applications or specific workloads optimized for that benchmark generation, the AMD chip offers significantly better performance. Its higher base clock of 2000 MHz likely contributes to its dominance in these scenarios, as does its simpler 8-core/8-thread design without hybrid scheduling overhead.

The Intel Core i5-1345UE wins in the more modern Cinebench R23 tests, which are more representative of current rendering workloads. It leads by 20.9% in multi-core and 7.3% in single-core. The Intel’s 10 cores and 12 threads, combined with its higher 4.60 GHz boost clock and larger 12 MB L3 cache, give it a clear advantage in contemporary multi-threaded applications. The Intel chip also supports newer DDR5 memory and PCIe Gen 4, which are advantages for system-level performance in new laptops.

For general productivity, the Intel chip’s higher R23 scores suggest it will handle modern video editing, 3D rendering, and code compilation better. The AMD chip’s R15 wins suggest it may still be competitive in older software or in scenarios where its higher base clock provides consistent performance. The average benchmark scores are nearly identical, with the AMD at 2722 and the Intel at 2698, so neither chip has a decisive edge in overall synthetic performance.

The Verdict

The data points to a clear recommendation based on workload age and type. The AMD Ryzen 7 4700U should be chosen by users who prioritize compatibility and performance in legacy applications, as evidenced by its 36.4% lead in Cinebench R15 single-core and 16.4% lead in R15 multi-core. Its 7 nm process and 8-core design also make it a capable choice for users who prefer AMD’s platform.

The Intel Core i5-1345UE is the better pick for modern workloads. Its 20.9% advantage in Cinebench R23 multi-core and 7.3% lead in R23 single-core show it is stronger in current rendering and productivity tasks. The support for DDR5 and PCIe Gen 4, along with a higher boost clock and larger L3 cache, make it the more future-proof option. Users running contemporary software should favor the Intel chip, while those stuck on older applications may find the AMD chip faster. Both sit at the 50th percentile, so neither is a high-end part, but the Intel chip’s newer architecture gives it the edge for today’s software.
