AMD Ryzen AI 7 345 vs Intel Core 7 253PE Comparison

Head-to-Head Benchmarks

The Intel Core 7 253PE dominates the recorded benchmark data against the AMD Ryzen AI 7 345, winning all 15 head-to-head comparisons. The largest margin appears in Cinebench R23 multi-core, where Intel scores 24,880 against AMD's 11,461, a 53.9% deficit. This gap reflects the Intel part's higher thread count and boost clock, and it is consistent across compute-heavy workloads.

Single-core performance also favors Intel decisively. In Cinebench R23 single-core, the Core 7 253PE posts 3,512 versus the Ryzen AI 7 345's 1,818, a 48.2% difference. The Cinebench R15 results tell the same story: Intel leads 354 to 271 in single-core (23.4% ahead) and 2,507 to 1,712 in multi-core (31.7% ahead). These margins indicate that the Intel processor holds a substantial advantage in both lightly threaded and fully threaded rendering tasks.

The PassMark suite reinforces the pattern. In integer math, Intel scores 114,158 against AMD's 63,475, a 44.4% lead. Floating-point math shows a 47.3% gap (80,870 vs. 42,621). Prime number finding is particularly lopsided: Intel produces 138 versus AMD's 62, a 55.1% deficit for the AMD chip. Data compression favors Intel by 30% (339,133 vs. 237,484), while data encryption shows a 35.7% gap (18,385 vs. 11,814).

The closest contest is PassMark single-thread, where Intel's 3,955 narrowly edges AMD's 3,875, a 2% difference. This suggests that in purely single-threaded, non-rendering tasks, the two processors are nearly equivalent, with the AMD part's Zen 5 architecture closing much of the gap that appears in Cinebench. However, the AMD chip wins no category outright. Even in physics simulation, where AMD's 1,089 trails Intel's 1,845 by 41%, the margin is substantial.

Random string sorting shows Intel ahead by 22.4% (32,777 vs. 25,435), and extended instructions favor Intel by 22% (21,806 vs. 17,003). The overall average benchmark score places the Intel part at 40,557 versus 29,461 for AMD, a 37.6% difference. The percentile rankings reflect this: Intel sits in the 87th percentile of all CPUs, while AMD ranks in the 81st.

Where Each One Wins

The Intel Core 7 253PE wins every measured workload category, but the size of the margin varies by task type. For heavily parallel workloads such as Cinebench R23 multi-core, 3D rendering, and integer math, the Intel part's 10 cores and 20 threads deliver a commanding lead. The 53.9% multi-core rendering advantage and 44.4% integer math edge make it the clear choice for content creation, compilation, and scientific computing.

In memory-intensive tasks like data compression and encryption, Intel also leads by 30% and 35.7%, respectively. These results suggest that the Intel processor handles large data sets and cryptographic workloads with greater efficiency. The 41% physics simulation gap further supports Intel's dominance in simulation and modeling tasks.

The AMD Ryzen AI 7 345, despite losing every benchmark, shows its closest performance in single-threaded PassMark tests. The 2% deficit there indicates that for everyday desktop responsiveness, web browsing, and light office work, the two processors would feel nearly identical. The AMD part's lower TDP of 28 watts versus Intel's 65 watts also positions it for thin-and-light mobile designs where thermal headroom is limited.

For workloads that rely heavily on single-core Cinebench performance, though, the Intel part's 48.2% lead in R23 single-core shows a significant architectural advantage in that specific rendering engine. Users running applications that depend on Cinebench-style single-thread performance would see a much larger difference than the PassMark single-thread results suggest.

Specification Differences

The two processors differ in nearly every core specification. The AMD Ryzen AI 7 345 has 6 cores and 12 threads, while the Intel Core 7 253PE has 10 cores and 20 threads. Base clocks are 2.00 GHz for AMD and 2.50 GHz for Intel; boost clocks are 4.60 GHz and 5.50 GHz, respectively.

Thermal design power differs substantially: AMD is rated at 28 watts, Intel at 65 watts. The AMD part uses socket FP8, while Intel uses Socket 1700. The AMD processor is built on a 4 nm process by TSMC, whereas Intel uses a 10 nm process at its own fabs. Cache configurations also diverge: both have 80 KB L1 per core, but AMD has 1 MB L2 per core and 4 MB L3, while Intel has 2 MB L2 per core and 33 MB shared L3.

Memory support differs as well. AMD supports DDR5 and LPDDR5X memory, while Intel supports DDR4 and DDR5. Both use dual-channel memory buses with 89.6 GB/s bandwidth. ECC memory is supported on Intel but not on AMD. PCIe capabilities favor Intel: it offers Gen 5 with 16 lanes, while AMD offers Gen 4 with 14 lanes.

The integrated graphics differ: AMD uses Radeon 840M, Intel uses UHD Graphics 730. Market segments also differ, with AMD targeting mobile and Intel targeting desktop. The AMD part has a release date of January 2025, while Intel's release date is March 2026. The Intel part has a launch MSRP of $384; the AMD part has no recorded launch MSRP.

Architecture Differences

The AMD Ryzen AI 7 345 uses the Krackan Point codename and belongs to the Ryzen AI 300 generation, which combines Zen 5 and Zen 5c cores. The Intel Core 7 253PE uses the Bartlett Lake codename and belongs to the Core 7 generation. The process node difference is notable: AMD uses TSMC's 4 nm process, while Intel uses its own 10 nm process.

The core count difference (6 vs. 10) and thread count difference (12 vs. 20) reflect distinct design philosophies. AMD's hybrid approach with Zen 5 and Zen 5c cores likely prioritizes power efficiency, consistent with its 28-watt TDP. Intel's 10-core design with a 65-watt TDP emphasizes raw throughput, which the benchmark data confirms.

Cache architecture differs significantly. AMD allocates 1 MB L2 per core and a small 4 MB shared L3, while Intel allocates 2 MB L2 per core and a large 33 MB shared L3. The larger L3 cache on Intel likely contributes to its advantages in data compression and random string sorting, workloads that benefit from larger pools of fast-access memory.

The integrated graphics differ in branding and likely capability: AMD's Radeon 840M versus Intel's UHD Graphics 730. The AMD part supports LPDDR5X memory, which is common in mobile designs, while Intel supports DDR4 and DDR5, reflecting its desktop orientation. Intel's support for ECC memory and PCIe Gen 5 with 16 lanes positions it for workstation-style use, while AMD's PCIe Gen 4 with 14 lanes and mobile socket target portable systems.
